I. EXECUTIVE SUMMARY

This report presents the findings of the energy audit conducted for:

Entity: Howell Township Board of Education

Facilities: Adelphia Elementary School Aldrich Elementary School Edith M. Griebling Elementary School Greenville Elementary School Land O’ Pines Elementary School Newbury Elementary School Ramtown Elementary School Taunton Elementary School Middle School North Middle School South Memorial Middle School Southard School

Municipal Contact Person: Ronald Sanasac, Business Administrator Facility Contact Person: Jeffrey Sharp, Director, Buildings and Grounds

This audit is performed in connection with the New Jersey Clean Energy - Local Government Energy Audit Program for Howell Township Public Schools. The purpose of this analysis is to provide the township insight into the energy savings potential that exists within facilities at Howell Township School District. Energy Efficiency changes and upgrades requires support from the building occupants, operations personnel and the administrators of the school district in order to maximize the savings and overall benefit. The efficiency improvement of public buildings provides a benefit for the environment and the residence of New Jersey. Through this report it has been demonstrated that there is a great potential for energy savings and infrastructure improvements at Howell Township School District. Fast Payback Energy Conservation Measures: The Energy Conservation Measures (ECMs) identified within the reports represent the potential annual savings at each facility. It is recommended to consider all ECMs as part of the township’s initiative to save energy, reduce emissions, and lower operating costs. Several ECMs shown within this report represent significant savings relative to the cost to implement. The ECMs shown with a simple payback of 10 years and less are considered very cost effective for a public entity such as Howell Township and should be considered a high priority for Howell Township Schools. The following ECMs are highly recommended throughout the schools.



Lighting Upgrades (All facilities) Lighting retrofits throughout the school district buildings are a straight forward conservation measure that is prescriptive in nature and provides substantial savings for the investment. Lighting retrofits are a good example of ECMs that can be implemented with “in house” staff to reduce the installation cost and further reduce paybacks. In many facilities such as the Classrooms and Libraries, the measure includes replacing existing 700 series T-8 fluorescent lamps with new higher efficiency T-8 lamps. In other facilities, a whole fixture replacement provides much more energy savings. Overall lighting upgrades represent one of the most easily implemented ECMs and are highly recommended throughout all Howell Schools.

Lighting Controls (Aldrich, Griebling, Land O’ Pines, Newbury, Ramtown, Taunton, Middle School North, Middle School South and Memorial Middle School)

Similar to lighting upgrades, lighting controls are very prescriptive in nature and can save considerable energy. Lighting controls do not require replacement of the fixture and typically can save more energy than lighting fixture upgrades. For the purpose of this energy audit, each ECM is calculated as stand-alone ECMs. The maximum savings can be achieved through the implementation of both the lighting upgrades and lighting controls ECMs. Lighting controls will automatically turn off lights when spaces and rooms are not occupied. It is important to note that ECMs are calculated as stand-alone ECMs and therefore the total savings will be slightly less than the sum of both individual ECMs (Lighting Upgrade and Lighting Controls). The discrepancy between additive ECMs is within the tolerances for this level of analysis (+/- 20%). Lighting controls provide the maximum savings in spaces that have changing occupancy schedules throughout the day. Offices with standard operating hours will also see substantial savings because all spaces are not occupied continuously. Lighting controls throughout Howell Schools is highly recommended in addition to the lighting upgrade ECMs.

Computer Monitor Replacement (All facilities) Plug loads within buildings is becoming a larger and larger portion of the total energy use for commercial facilities. Plug loads are most dominant in combination with computers and computer equipment. Modern computer monitors are flat screen LCD panels that are far more efficiency than older style cathode ray-tube (CRT) monitors. Typical energy use of a flat screen monitor is approximately 1/3 of the energy used by a CRT monitor. The majority of computer monitors within the facilities are LCD style monitors. However, almost all of the Howell Schools utilize some CRT monitors. It is highly recommended to replace the existing CRT monitors with flat screen monitors to take advantage of the energy savings as well as other ergonomic benefits of modern LCD monitors.

Computer Power Management (All facilities) It was noticed that computers were left ON due to long booting times of the older computers. Many personal computers (PC) came equipped with automatic Stand-by or Hibernate (power down) features. Normally computers boot up from Stand-by or Hibernate modes much faster



than powering up from Shut Down position. It is recommended to set up the PCs at this facility to switch into Stand-by Mode after a short period of inactivity and Hibernate mode after a long period of inactivity.

High Efficiency Domestic Hot Water Heaters Older and outdated gas fired domestic hot water heaters can be replaced with high efficiency condensing hot water heaters. In addition, electric domestic hot water heaters cost over three (3) times more than gas fired domestic hot water heaters. It is recommended to upgrade older inefficient domestic hot water heaters. Capital Improvement Energy Conservation Measures: The ECMs that have much longer paybacks are considered capital improvement ECMs. These ECMs typically have high installation costs that are more difficult to justify the savings based solely on the energy savings associated with the improvement. Despite the long paybacks, these ECMs in many cases provide valuable and much needed infrastructure improvements for the facility. These ECMs include boiler upgrades, HVAC equipment upgrades, control system upgrades, unit ventilator upgrades as well as other large HVAC equipment replacements. The savings identified for the following ECMs provides additional incentive for Howell BOE’s capital improvement projects.

Combined Project Approach: Although individual projects with a simple payback of 10 years and less are considered financially self-sustaining, it is important to consider how multiple projects can be combined together. When ECMs are aggregated into a single project, the lower cost ECMs provides valuable savings to offset the higher cost ECMs. Likewise when multiple facilities are aggregated together into a single entity energy efficiency project, the same benefits are seen on a larger scale. The Energy Savings Improvement Program (ESIP) allows for financing of any combination of energy efficiency projects across multiple facilities into one large project. The term of the financing must be under 15 years and the savings provides the revenue for the financing cost. The combination of all facilities into one large energy efficiency project provides Howell BOE with the opportunity to implement all ECMs identified within this report with an overall simple payback of 13 years. This option allows Howell BOE to implement much needed infrastructure improvements. The program financing allows for the implementation with no upfront cost for Howell BOE. Implementation of an ESIP provides significant benefits and should be strongly considered for Howell. The Total Entity Project Summary table below shows the savings, costs, incentives and paybacks for all ECMs at Howell Township Public Schools.

Howell BOE has the option to utilize the Direct Install program for their Aldrich Elementary, Griebling Elementary, Taunton Elementary and Southard School facilities. These facilities fall within the Direct Install program’s 150 kW maximum peak demand requirement and have projects that can utilize the program’s generous 70% state incentive to further reduce the project costs. When utilizing Direct Install in lieu of the Smart Start incentive for eligible measures, the BOE is eligible for a $75,000 maximum incentive.. The eligibility of the ECMs are dependent on the facility evaluation through the program and must be verified through the program contractor. This approach maximizes the savings for Howell BOE and will aid in reducing the overall project payback. It is highly recommended to utilize all available incentives including Direct Install by contacting the Direct Install Contractor to perform the site evaluation for the noted facilities.

Implementation of all ECMs identified within the ESIP - Entity Total Project Summary table represents a total annual savings of approximately $345,857 for Howell Schools. The individual facility project summaries are shown within each facility energy audit report.



Other Considerations:

Maintenance and Operational Measures In addition to the ECMs, there are maintenance and operational measures that can provide significant energy savings and provide immediate benefit. The ECMs listed above represent investments that can be made to the facility which are justified by the savings seen overtime. However, the maintenance items and small operational improvements below are typically achievable with onsite staff or maintenance contractors and in turn have the potential to provide substantial operational savings compared to the costs associated. The following are recommendations which should be considered a priority when moving forward with energy efficiency upgrades: 1. Chemically clean condenser and evaporator coils periodically to optimize efficiency. Poorly

maintained heat transfer surfaces can reduce efficiency 5-10%. 2. Maintain all weather stripping on entrance doors to limit unnecessary infiltration. 3. Clean all light fixtures to maximize light output to provide better light output and avoid the

use of task lighting where otherwise not necessary. 4. Provide more frequent air filter changes to decrease overall system power usage and maintain

better IAQ.

Renewable Energy Measures Renewable Energy Measures (REMs) were also reviewed for implementation at Howell Schools. CEG utilized a combination of roof mounted solar arrays and canopy style parking lot solar arrays to house PV systems throughout the school buildings. The total solar electric production potential for these systems is approximately 3,434,685 kWh, which would reduce school district’s grid purchased electric energy by 35%. The system’s calculated simple payback of approximately 8.8 years is within the standard 10 year simple payback threshold; in addition, with alternative funding this payback could be lessened. Concord Engineering recommends the Owner review all funding options available with the implementation of this renewable energy measure. Overall Assessment: Overall, most of the Howell Schools are maintained and operating below the average efficiency of similar type of facilities. There are numerous ECMs that can be implemented to reduce energy use and save on the individual facility’s operating costs. The total energy cost of $2,210,059 could be reduced by approximately 15.6% through the implementation of the ECMs recommended in this audit. The Howell Township Board of Education is in a unique position to implement energy efficiency improvements and still include large capital projects. Since the total project is capable of being funded through the savings, CEG highly recommends the Board to take advantage of this opportunity.



II. INTRODUCTION The comprehensive energy audit covers the following Schools in Howell Township:

Adelphia Elementary School Aldrich Elementary School Edith M. Griebling Elementary School Greenville Elementary School Land O’ Pines Elementary School Newbury Elementary School Ramtown Elementary School Taunton Elementary School Middle School North Middle School South Memorial Middle School Southard School

This audit is performed in connection with the New Jersey Clean Energy - Local Government Energy Audit Program. The energy audit is conducted to promote the mission of the office of Clean Energy, which is to use innovation and technology to solve energy and environmental problems in a way that improves the State’s economy. This can be achieved through the wiser and more efficient use of energy. Electrical and natural gas utility information is collected and analyzed for one full year’s energy use of each building. The utility information allows for analysis of the building’s operational characteristics; calculate energy benchmarks for comparison to industry averages, estimated savings potential, and baseline usage/cost to monitor the effectiveness of implemented measures. A computer spreadsheet is used to calculate benchmarks and to graph utility information (see the utility profiles below). The Energy Use Index (EUI) is established for the building. Energy Use Index (EUI) is expressed in British Thermal Units/square foot/year (BTU/ft2/yr), which is used to compare energy consumption to similar building types or to track consumption from year to year in the same building. The EUI is calculated by converting the annual consumption of all energy sources to BTU’s and dividing by the area (gross square footage) of the building. Blueprints (where available) are utilized to verify the gross area of the facility. The EUI is a good indicator of the relative potential for energy savings. A low EUI indicates less potential for energy savings, while a high EUI indicates poor building performance therefore a high potential for energy savings. Existing building architectural and engineering drawings (where available) are utilized for additional background information. The building envelope, lighting systems, HVAC equipment, and controls information gathered from building drawings allow for a more accurate and detailed review of the building. The information is compared to the energy usage profiles developed from utility data. Through the review of the architectural and engineering drawings a building



profile can be defined that documents building age, type, usage, major energy consuming equipment or systems, etc. The preliminary audit information is gathered in preparation for the site survey. The site survey provides critical information in deciphering where energy is spent and opportunities exist within a facility. The entire site is surveyed to inventory the following to gain an understanding of how each facility operates:

Building envelope (roof, windows, etc.) Heating, ventilation, and air conditioning equipment (HVAC) Lighting systems and controls Facility-specific equipment

The building site visit is performed to survey all major building components and systems. The site visit includes detailed inspection of energy consuming components. Summary of building occupancy schedules, operating and maintenance practices, and energy management programs provided by the building manager are collected along with the system and components to determine a more accurate impact on energy consumption.



III. METHOD OF ANALYSIS

This audit is consistent with an ASHRAE level 2 audit. The cost and savings for each measure is ± 20%. The evaluations are based on engineering estimations and industry standard calculation methods. More detailed analyses would require engineering simulation models, hard equipment specifications, and contractor bid pricing. Post site visit work includes evaluation of the information gathered, researching possible conservation opportunities, organizing the audit into a comprehensive report, and making recommendations on HVAC, lighting and building envelope improvements. Data collected is processed using energy engineering calculations to anticipate energy usage for each of the proposed energy conservation measures (ECMs). The actual building’s energy usage is entered directly from the utility bills provided by the owner. The anticipated energy usage is compared to the historical data to determine energy savings for the proposed ECMs. It is pertinent to note, that the savings noted in this report are not additive. The savings for each recommendation is calculated as standalone energy conservation measures. Implementation of more than one ECM may in some cases affect the savings of each ECM. The savings may in some cases be relatively higher if an individual ECM is implemented in lieu of multiple recommended ECMs. For example implementing reduced operating schedules for inefficient lighting will result in a greater relative savings. Implementing reduced operating schedules for newly installed efficient lighting will result in a lower relative savings, because there is less energy to be saved. The project / Entity summary tables are based on the implementation of multiple measures. The analysis is reviewed and determined if the nature of the ECMs will cause a major conflict of the overall savings. When additive measures do not cause a major effect on the overall savings the ECMs are included. Where a major conflict is identified, the combined savings is evaluated appropriately to ensure the overall estimates are ± 20%. ECMs are determined by identifying the building’s unique properties and deciphering the most beneficial energy saving measures available that meet the specific needs of the facility. The building construction type, function, operational schedule, existing conditions, and foreseen future plans are critical in the evaluation and final recommendations. Energy savings are calculated base on industry standard methods and engineering estimations. Energy consumption is calculated based on manufacturer’s cataloged information when new equipment is proposed. Cost savings are calculated based on the actual historical energy costs for the facility. Installation costs include labor and equipment costs to estimate the full up-front investment required to implement a change. Costs are derived from Means Cost Data, industry publications, and local contractors and equipment suppliers. The NJ Smart Start Building® program incentives savings (where applicable) are included for the appropriate ECM’s and subtracted from the installed cost. Maintenance savings are calculated where applicable and added to the energy savings for each ECM. The life-time for each ECM is estimated based on the typical life of the equipment being replaced or altered. The costs and savings are applied and a simple payback, simple lifetime savings, and simple return on investment are calculated. See below for calculation methods:

B. Energy Use Index (EUI) Energy Use Index (EUI) is a measure of a building’s annual energy utilization per square foot of building. This calculation is completed by converting all utility usage consumed by a building for one year, to British Thermal Units (BTU) and dividing this number by the building square footage. EUI is a good measure of a building’s energy use and is utilized regularly for comparison of energy performance for similar building types. The Oak Ridge National Laboratory (ORNL) Buildings Technology Center under a contract with the U.S. Department of Energy maintains a Benchmarking Building Energy Performance Program. The ORNL website determines how a building’s energy use compares with similar facilities throughout the U.S. and in a specific region or state. Source use differs from site usage when comparing a building’s energy consumption with the national average. Site energy use is the energy consumed by the building at the building site only. Source energy use includes the site energy use as well as all of the losses to create and distribute the energy to the building. Source energy represents the total amount of raw fuel that is required to operate the building. It incorporates all transmission, delivery, and production losses, which allows for a complete assessment of energy efficiency in a building. The type of utility purchased has a substantial impact on the source energy use of a building. The EPA has determined that source energy is the most comparable unit for evaluation purposes and overall global impact. Both the site and source EUI ratings for the building are provided to understand and compare the differences in energy use. The site and source EUI for this facility is calculated as follows:

C. EPA Energy Benchmarking System The United States Environmental Protection Agency (EPA) in an effort to promote energy management has created a system for benchmarking energy use amongst various end users. The benchmarking tool utilized for this analysis is entitled Portfolio Manager. The Portfolio Manager tool allows tracking and assessment of energy consumption via the template forms located on the ENERGY STAR website (www.energystar.gov). The importance of benchmarking for local government municipalities is becoming more important as utility costs continue to increase and emphasis is being placed on carbon reduction, greenhouse gas emissions and other environmental impacts. Based on information gathered from the ENERGY STAR website, Government agencies spend more than $10 billion a year on energy to provide public services and meet constituent needs. Furthermore, energy use in commercial buildings and industrial facilities is responsible for more than 50 percent of U.S. carbon dioxide emissions. It is vital that local government municipalities assess facility energy usage, benchmark energy usage utilizing Portfolio Manager, set priorities and goals to lessen energy usage and move forward with priorities and goals. In accordance with the Local Government Energy Audit Program, CEG has created an ENERGY STAR account for the municipality to access and monitoring the facility’s yearly energy usage as it compares to facilities of similar type. The login page for the account can be accessed at the following web address; the username and password are also listed below:

V. RENEWABLE/DISTRIBUTED ENERGY MEASURES Globally, renewable energy has become a priority affecting international and domestic energy policy. The State of New Jersey has taken a proactive approach, and has recently adopted in its Energy Master Plan a goal of 30% renewable energy by 2020. To help reach this goal New Jersey created the Office of Clean Energy under the direction of the Board of Public Utilities and instituted a Renewable Energy Incentive Program to provide additional funding to private and public entities for installing qualified renewable technologies. A renewable energy source can greatly reduce a building’s operating expenses while producing clean environmentally friendly energy. CEG has assessed the feasibility of installing renewable energy measures (REM) for the municipality utilizing renewable technologies and concluded that there is potential for solar energy generation. Solar Generation Solar energy produces clean energy and reduces a building’s carbon footprint. This is accomplished via photovoltaic panels which are mounted on all south and southwestern facades of the building. Flat roof, as well as sloped areas can be utilized; flat areas will have the panels turned to an optimum solar absorbing angle. (A structural survey of the roof would be necessary before the installation of PV panels is considered). Parking lots can also be utilized for the installation of a solar array. A truss system can be installed that is high enough to park vehicles under the array and no parking lot area is lost. The state of NJ has instituted a program in which one Solar Renewable Energy Certificate (SREC) is given to the Owner for every 1000 kWh of generation. SREC’s can be sold anytime on the market at their current market value. The value of the credit varies upon the current need of the power companies. The average value per credit used in our financial calculations is $204 per MWH. This equates to $0.204 per kWh generated. CE has reviewed the existing roof area potential of the facilities included in this audit for the purposes of determining a potential for a photovoltaic system.. Some areas were not included due to potential shading from campus buildings and surrounding trees. A depiction of the area utilized at each facility is shown in Renewable / Distributed Energy Measures Calculation Appendices in the building reports. The system sizes are shown below for each building where installation of a solar PV system is feasible. The total KWH production for all facilities combined is 3,434685 kWh annually, reducing the overall utility bill for the school district by approximately 35% percent. A detailed financial analysis can be found in the Renewable / Distributed Energy Measures Calculation Appendix within each facility report. This analysis illustrates the payback of the system over a 15 year period. The eventual degradation of the solar panels and the price of accumulated SREC’s are factored into the payback.

POWER PRODUCTION SUMMARY - PHOTOVOLTAIC SYSTEM PER FACILITY

FACILITY PRODUCTION SUMMARY

The proposed photovoltaic array layouts are designed based on the specifications for the Sun Power SPR-230 panel. This panel has a “DC” rated full load output of 230 watts, and has a total panel conversion efficiency of 18%. Although panels rated at higher wattages are available through Sun Power and other various manufacturers, in general most manufacturers who produce commercially available solar panels produce a similar panel in the 200 to 250 watt range. This provides more manufacturer options to the public entity if they wish to pursue the proposed solar recommendation without losing significant system capacity. The array system capacity was sized based on available roof space or canopy style system area available at each existing facility. Estimated solar array generation is calculated based on the National Renewable Energy Laboratory PVWatts Version 1.0 Calculator. In order to calculate the array generation an appropriate location with solar data on file must be selected. In addition the system DC rated kilowatt (kW) capacity must be inputted, a DC to AC de-rate factor, panel



tilt angle, and array azimuth angle. The DC to AC de-rate factor is based on the panel nameplate DC rating, inverter and transformer efficiencies (95%), mismatch factor (98%), diodes and connections (100%), dc and ac wiring(98%, 99%), soiling, (95%), system availability (95%), shading (if applicable), and age(new/100%). The overall DC to AC de-rate factor has been calculated at an overall rating of 81%. The PVWatts Calculator program then calculates estimated system generation based on average monthly solar irradiance and user provided inputs. The monthly energy generation and offset electric costs from the PVWatts calculator is shown in the Renewable/Distributed Energy Measures Calculation Appendix within each facility report. The proposed solar array for each facility is qualified by the New Jersey Board of Public Utilities Net Metering Guidelines as a Class I Renewable Energy Source. These guidelines allow onsite customer generation using renewable energy sources such as solar and wind with a capacity of 2 megawatts (MW) or less. This limits a customer system design capacity to being a net user and not a net generator of electricity on an annual basis. Although these guidelines state that if a customer does net generate (produce more electricity than they use), the customer will be credited those kilowatt-hours generated to be carried over for future usage on a month to month basis. Then, on an annual basis if the customer is a net generator the customer will then be compensated by the utility the average annual PJM Grid LMP price per kilowatt-hour for the over generation. Due to the aforementioned legislation, the customer is at limited risk if they generate more than they use at times throughout the year. With the inefficiency of today’s energy storage systems, such as batteries, the added cost of storage systems is not warranted and was not considered in the proposed design. Direct purchase involves School District paying for 100% of the total project cost upfront in lieu of one of the methods noted in the Installation Funding Options section below. Calculations include a utility inflation rate as well as the degradation of the solar panels over time. The financial summary per facility is as follows:

FINANCIAL SUMMARY - PHOTOVOLTAIC SYSTEM PER FACILITY

FACILITY DIRECT PURCHASE FINANCIAL SUMMARY

CEG recommends Howell Township BOE review all options available for installation of solar PV systems at their facilities including a Power Purchase Agreement (PPA). This option utilizes providers who will own, operate, and maintain the system for a period of 15 years. During this time the PPA Provider would sell all of the electric generated by Solar Arrays to the district at a reduced rate compared to their existing electric rate. Wind Generation In addition to the Solar Analysis, CEG also conducted a review of the applicability of wind energy for the facility. Wind energy production is another option available through the Renewable Energy Incentive Program. Wind turbines of various types can be utilized to produce clean energy on a per building basis. Cash incentives are available per kWh of electric usage. Based on CEG’s review of the applicability of wind energy for the facility, it was determined that the average wind speed of 5 m/s is not adequate, and available space is very limited for



purchase of a commercial wind turbine. Therefore, wind energy is not a viable option to implement.



VI. ENERGY PURCHASING AND PROCUREMENT STRATEGY Load Profile: Load Profile analysis was performed to determine the seasonal energy usage of the facilities in the Howell Township BOE. Irregularities in the load profile will indicate potential problems within the facility. Consequently based on the profile a recommendation will be made to remedy the irregularity in energy usage. For this report, the individual facility’s energy consumption data was gathered in table format and plotted in graph form to create the load profile. Refer to the Electric and Natural Gas Usage Profiles included within the individual facility’s report to reference the respective electricity and natural gas usage load profiles. Electricity: The electricity usage profile demonstrates a steady yearlong load profile for facilities that have occupancy during the summer months. The average monthly usage for all accounts combined is 806,869 kWh. The historical usage profile is beneficial and will allow for more competitive energy prices when shopping for alternative suppliers mainly due to the relatively flat and higher winter usage load profile. Third Party Supplier (TPS) electric commodity contracts that offer’s a firm, fixed price for 100% of the facilities electric requirements and are lower than the JCPL’s BGS-FP default rate are recommended. Natural Gas: The Natural Gas Usage Profile demonstrates a very typical natural gas (heat load) profile for all facilities. The average monthly winter (Nov-Mar) consumption of all facilities is 104,236 therms and the average monthly summer (Apr-Oct) consumption is 24,498 therms. This load profile will yield less favorable natural gas fixed pricing when shopping for alternative suppliers. This is because the higher winter month consumption will yield higher pricing which will not be offset by the summer month consumption. Nymex commodity pricing is generally higher in the winter months of November – March and lower in the summer months of April – October. Obtaining a flat load profile, (usage is similar each month), will yield optimum natural gas pricing when shopping for alternative suppliers. Third Party Supplier (TPS) natural gas commodity contracts that offer a product structure to include either 1) a fixed basis rate with a market based Nymex/commodity rate or 2) a fixed basis rate with fixed Nymex/commodity winter rate (Nov – March) and market based Nymex/commodity rate for the summer months (April – October) for 100% of the facilities metered natural gas requirements are both recommended due to current market pricing.



Tariff Analysis: Electricity: Every facility receives electrical service through JCP&L’s rate tariff, General Service Secondary (GSS). Some of the facilities are under a Third Party Supplier (TPS) to provide electric commodity service. These Facilities are Adelphia, Griebling, Greenville, Middle School North, Middle School South and Memorial Middle School. The rest of the schools are receiving electric distribution and electric commodity service directly from the utility. For electric supply (generation) service, the client has a choice to either use JCP&L’s default service rate BGS-FP or contract with a Third Party Supplier (TPS) to supply electric. Each year since 2002, the four New Jersey Electric Distribution Companies (EDCs) - Public Service Gas & Electric Company (PSE&G), Atlantic City Electric Company (ACE), Jersey Central Power & Light Company (JCP&L), and Rockland Electric Company (RECO) - have procured several billion dollars of electric supply to serve their Basic Generation Service (BGS) customers through a statewide auction process held in February. BGS refers to the service of customers who are not served by a third party supplier or competitive retailer. This service is sometimes known as Standard Offer Service, Default Service, or Provider of Last Resort Service. The Auction Process has consisted of two auctions that are held concurrently, one for larger customers on an hourly price plan (BGS-CIEP) and one for smaller commercial and residential customers on a fixed-price plan (BGS-FP). This facility’s rate structure is based on the fixed-price plan (BGS-FP). The utility, JCP&L will continue to be responsible for maintaining the existing network of wires, pipes and poles that make up the delivery system, which will serve all consumers, regardless of whom they choose to purchase their electricity or natural gas from. JCP&L’s Delivery Service rate includes the following charges: Customer Charge, Supplemental Customer Charge, Distribution Charge (kW Demand), kWh Charge, Non-utility Generation Charge, TEFA, SBC, SCC, Standby Fee and RGGI. Natural Gas: All facilities currently receive natural gas distribution service through New Jersey Natural Gas (NJNG) on rate schedules GSL (General Service Large). The facilities are currently receiving natural gas supply service from Hess Energy, a Third Party Supply Contractor. For natural gas supply service, the client has a choice to either use NJNG’s default service rate BGSS or contract with a Third Party Supplier (TPS) to supply natural gas. NJNG provides basic gas supply service (BGSS) to customers who choose not to shop from a Third Party Supplier (TPS) for natural gas commodity. The option is essential to protect the reliability of service to consumers as well as protecting consumers if a third party supplier



defaults or fails to provide commodity service. Please refer to the links below for a recap of monthly natural gas BGSS charges from NJNG. https://www.njng.com/pdf/Dec2011SmallComPrices.pdf https://www.njng.com/pdf/Dec2011LargeComPrices.pdf The utility, NJNG is responsible for maintaining the existing network of underground pipes that make up the delivery system, which will serve all consumers, regardless of whom they choose to purchase their natural gas from. NJNG’s delivery service rates include the following charges: Customer Service Charge, Delivery Charge, and Demand Charges.

Electric and Natural Gas Commodities Market Overview:

Current electricity and natural gas market pricing has remained relatively stable over the last year. Commodity pricing in 2008 marked historical highs in both natural gas and electricity commodity. Commodity pricing commencing spring of 2009 continuing through 2011, has decreased dramatically over 2008 historic highs and continues to be favorable for locking in long term (2-5 year) contracts with 3rd Party Supplier’s for both natural gas and electricity supply requirements.

It is important to note that both natural gas and electric commodity market prices are moved by supply and demand, political conditions, market technicals and trader sentiment. This market is continuously changing. Energy commodity pricing is also correlated to weather forecasts. Because weather forecasts are dependable only in the short-term, prolonged temperature extremes can really cause extreme price swings.

Short Term Energy Outlook - US Energy Information Administration (1/10/2012):

U.S. Natural Gas Prices. At this time last year, EIA had projected that the Henry Hub natural gas spot price would average $4.02 per MMBtu in 2011, rising to an average $4.50 per MMBtu in 2012. The final average Henry Hub spot price for 2011 was $4.00 per MMBtu. The current forecast for 2012 natural gas prices is significantly lower than at this time last year, as continued growth in production and a very warm start to the winter have contributed to record-high natural gas inventories. EIA now expects the Henry Hub spot price will average $3.53 per MMBTU in 2012. In 2013, the forecast spot price rises to an average of $4.14 per MMBtu. Natural gas futures prices for March 2012 delivery (for the 5-day period ending January 5, 2012) averaged $3.05 per MMBtu, and the average implied volatility was 40 percent. The lower and upper bounds for the 95-percent confidence interval for March 2012 contracts are $2.29 per MMBtu and $4.06 per MMBtu. At this time last year, the March 2011 natural gas futures contract averaged $4.39 per MMBtu and implied volatility averaged 43 percent. The corresponding lower and upper limits of the 95-percent confidence interval were $3.21 per MMBtu and $6.02 per MMBtu.

U.S. Electricity Retail Prices. After having risen by 2.1 percent between 2010 and 2011, EIA expects average U.S. residential electricity prices to rise only 0.6 percent in 2012 and then stay flat in 2013.



Pricing in the chart above includes both utility distribution and energy commodity charges.



Recommendations:

1. CEG recommends an aggregated approach for 3rd party commodity supply procurement strategies for electricity supply service at all of the facilities. Aggregating all Howell Township Board of Education facilities for electricity would allow for all facilities to achieve cost reductions on electricity supply costs. Energy commodities are among the most volatile of all commodities, however at this point and time, energy is extremely competitive. The facilities could realize up to a 30% reduction in energy supply costs, if it were to aggregate all facilities usage and take advantage of these current market prices quickly, before energy increases.

Overall, after review of the utility consumption, billing, and current commodity pricing outlook, CEG recommends that Howell BOE continue with the NJSBA “ACES” energy consortium or explore the utilization and advisement of their own 3rd party unbiased Energy Consulting Firm. This firm should be experienced in the procurement of electricity commodity, New Jersey procurement laws, aggregation of facilities and energy supply risk and commodity management. In addition, the firm should be able to provide full service advisement over the term of the contract to identify additional opportunities to further reduce costs. Many of these opportunities may include: energy rates; utility bill auditing; energy data analytics; and efficiency improvements.

It is important that a rational, defensible strategy for purchasing commodity in volatile markets is incorporated. Examples include:

Budgets that reflect sound market intelligence An understanding of BGS historical prices and trends Awareness of seasonal opportunities (e.g. shoulder months) Negotiation of fair contractual terms An aggressive, market based price

2. CEG recommends that the Howell BOE consider utilizing a third party utility billing-auditing service to further analyze historical utility invoices such as water, sewer, natural gas and electric for incorrect billings and rate tariff optimization services. This service can be based on a shared savings model with no cost to Howell BOE. The service could provide refunds on potential incorrect billings that may have been passed through by the utilities and or supplier and paid by Howell BOE.

3. CEG recommends that Howell BOE explore an aggregated Demand Response Program

that may be available in aggregate for its facilities. Demand response is the action of end users lowering their demand for electric (reducing consumption) in order to help balance supply and demand on the electric grid and ensure stability. The greatest need for demand response typically occurs during times of peak electricity demand, between the hours of 11 am and 6 pm, when extra strain is placed on the grid from situations such as increased air conditioning use on hot days or downed power lines resulting from a storm. Significant incentives are available for clients enrolled in demand response programs. It is strongly recommended that Howell BOE utilize an experienced 3rd party unbiased



energy consulting firm prior to initiating any demand response programs. This is recommended due to the potential conflicts with existing and/or future electric supply service agreements and transparency created by the evaluation of current programs and incentives available.

The recommendations and projected savings presented by CEG are based on current information provided by Howell BOE for its facilities utility usage. Any projected savings presented with these recommendations are estimates only based on that information. It is recommended that further analysis and review of more recent utility data and actual Third Party Suppler invoices and contracts be performed prior to performing any of the presented recommendations.



VII. INSTALLATION FUNDING OPTIONS CEG has reviewed various funding options for the facility owner to utilize in subsidizing the costs for installing the energy conservation measures noted within this report. Below are a few alternative funding methods: A. Incentive Programs: Pay For Performance The New Jersey Smart Start Pay for Performance program includes incentives based on savings resulted from implemented ECMs. The program is available for all buildings that were audited as part of the NJ Clean Energy’s Local Government Energy Audit Program. The facility’s participation in the program is assisted by an approved program partner. An “Energy Reduction Plan” is created with the facility and approved partner to shown at least 15% reduction in the building’s current energy use. Multiple energy conservation measures implemented together are applicable toward the total savings of at least 15%. No more than 50% of the total energy savings can result from lighting upgrades / changes.

Total incentive is capped at 50% of the project cost. The program savings is broken down into three benchmarks; Energy Reduction Plan, Project Implementation, and Measurement and Verification. Each step provides additional incentives as the energy reduction project continues. The benchmark incentives are as follows:

1. Energy Reduction Plan – Upon completion of an energy reduction

plan by an approved program partner, the incentive will grant $0.10 per square foot between $5,000 and $50,000, and not to exceed 50% of the facility’s annual energy expense. (Benchmark #1 is not provided in addition to the local government energy audit program incentive.)

2. Project Implementation – Upon installation of the recommended measures along with the “Substantial Completion Construction Report,” the incentive will grant savings per KWH or Therm based on the program’s rates. Minimum saving must be 15%. (Example $0.11 / kWh for 15% savings, $0.12/ kWh for 17% savings, … and $1.10 / Therm for 15% savings, $1.20 / Therm for 17% saving, …) Increased incentives result from projected savings above 15%.

3. Measurement and Verification – Upon verification 12 months after implementation of all recommended measures, that actual savings have been achieved, based on a completed verification report, the incentive will grant additional savings per kWh or Therm based on the program’s rates. Minimum savings must be 15%. (Example $0.07 / kWh for 15% savings, $0.08/ kWh for 17% savings, … and



$0.70 / Therm for 15% savings, $0.80 / Therm for 17% saving, …) Increased incentives result from verified savings above 15%.

Direct Install Program The New Jersey Clean Energy’s Direct Install Program is a state funded program that targets small commercial and industrial facilities with peak demand of less than 150 kW. This turnkey program is aimed at providing owners a seamless, comprehensive process for analysis, equipment replacement and financial incentives to reduce consumption, lower utility costs and improve profitability. The program covers up to 70% of the cost for eligible upgrades including lighting, lighting controls, refrigeration, HVAC, motors, variable speed drives, natural gas and food service. Participating contractors (refer to www.njcleanenergy.com) conduct energy assessments in addition to your standard local government energy audit and install the cost-effective measures. The following measures are potential candidates for Direct Install:

Lighting Upgrade Lighting Controls NEMA Premium Efficiency Motors Rooftop Unit Replacement

Smart Start Program

Prescriptive Measures - The New Jersey Clean Energy’s Smart Start prescriptive measures incentives include unit pricing incentives for installation of energy efficient equipment and controls. Proposed equipment and controls must meet the minimum efficiency requirements as well as other application requirements. The Smart Start prescriptive incentives applicable for new construction, renovations, remodeling and equipment replacements, for a wide range of equipment including:

Electric Chillers Gas Cooling Electric Unitary HVAC Ground Source Heat Pumps Gas Heating Variable Frequency Drives Gas Water Heating Premium Motors Prescriptive Lighting Lighting Controls Technical Studies

Custom Measures - The New Jersey Clean Energy’s Smart Start prescriptive measures incentives include all measures not identified in the prescriptive measures category or measures that must have savings verified through additional analysis such as energy model simulations. Custom measures are intended to include savings as a result of unique



energy efficiency measures, which are typically facility specific such as waste heat recovery. Custom incentives are provided based on the amount of energy saved and minimum internal rate of return in order to be eligible.

CEG recommends the Owner review the use of the above-listed funding options in addition to utilizing their standard method of financing for facilities upgrades in order to fund the proposed energy conservation measures.



B. Financing Options: Municipal Bonds Municipal bonds are a bond issued by a city or other local government, or their agencies. Potential issuers of municipal bonds include cities, counties, redevelopment agencies, school districts, publicly owned airports and seaports, and any other governmental entity (or group of governments) below the state level. Municipal bonds may be general obligations of the issuer or secured by specified revenues. Interest income received by holders of municipal bonds is often exempt from the federal income tax and from the income tax of the state in which they are issued, although municipal bonds issued for certain purposes may not be tax exempt. Power Purchase Agreement Public Law 2008, Chapter 3 authorizes contracts of up to fifteen (15) years for energy purchase contracts commonly known as “power purchase agreements.” These are programs where the contracting unit (Owner) procures a contract for, in most cases, a third party to install, maintain, and own a renewable energy system. These renewable energy systems are typically solar panels, windmills or other systems that create renewable energy. In exchange for the third party’s work of installing, maintaining and owning the renewable energy system, the contracting unit (Owner) agrees to purchase the power generated by the renewable energy system from the third party at agreed upon energy rates. Energy Savings Improvement Program (ESIP): Public Law 2009, Chapter 4 authorizes government entities to make energy related improvements to their facilities and pay for the costs using the value of energy savings that result from the improvements. The “Energy Savings Improvement Program (ESIP)” law provides a flexible approach that can allow all government agencies in New Jersey to improve and reduce energy usage with minimal expenditure of new financial resources. This program provides public entities to make valuable facility infrastructure improvements that are associated with energy savings. All energy savings projects are eligible as long as the financing period does not extend beyond 15 years. The financing can be utilized for all aspects of energy efficiency project implementation including, energy savings plan development, engineering, construction management, construction management, commissioning, and measurement and verification. This program provides the much needed financing for energy efficiency projects without the burden of increased debt. The program allows for procurement of financing without voter approval or extending existing dept. The program requires evaluation to ensure a positive cash-flow through the entire 15 year financing period. The first phase of implementing an ESIP is the development of an Energy Savings Plan (ESP) to verify the energy savings, construction costs, and overall financial model. The underlining program requirement is the limitation of the project term to 15 years. The ESIP project size is open for multiple buildings to be included within one project. In addition all applicable incentive programs can also be utilized to help reduce the overall construction cost.



The following breakdown is an estimated project scope with the potential to qualify for the ESIP. An ESP is required to verify the costs and savings as part of an ESIP project.
