    Energy Modeling Guidelines for Estimating Incremental Generation

    I. STANDARD MODEL FOR USE AT SITES WITHDAMS ON RIVERS (NOT CONDUITS)

    Develop a numerical model, preferably Excel-based o Preferred: Daily dispatch using average daily gauge flows for the period of record o Alternative for simple projects (single unit or multiple identical units) with no seasonal

    changes in operation: Flow duration analysis may be acceptable Hydrology

    o Prefer 30-yr period of record longer, if available o Prorated to drainage area of the project o If river/stream is ungauged or period of record is less than 20 years consider two or more

    surrogate gauges with 30+ years of record to synthesize flow data Headwater and tailwater relationship as a function of flow

    o If not available, assume tailwater rises twice as fast as headwater Environmental requirements, known or best estimates for:

    o Minimum flow releases o Fishery releases o Operating restrictions o Other

    Model each hydro-turbine generating unit, existing and proposed o Operating range for each turbine o Equipment efficiencies (turbines, speed increasers, generators & transformers) o Develop a dispatch table (priority and loading of units on and off) o Headlosses (canal, intake, racks, penstock, pressure case, draft tube & tailrace) as a function

    of flow. Calculate headlosses, measure net head or conservatively estimate full load headloss and then develop relationship for headloss as a function of turbine flow squared.

    o Exception: For simple projects with a single unit or multiple identical units, it may be possible to model the entire plant as a single unit.

    Calibration o If baseline conditions include existing units, calibrate modeled generation to historic

    production o Take into account outages and station service losses o If period of record is short, consider calibrating on a monthly basis o If there are no historic data to calibrate to, consider one or more additional steps

    Have a qualified party perform a second, independent model study (ideal, but not required by MassCEC)

    Have a qualified party independently confirm key model inputs (headwater, tailwater, flows, efficiencies, headlosses, etc.) and the energy calculations

    Perform an annual flow duration analysis with 100 data points and compare results to daily dispatch model

    Run calibrated model over the period of record and calculate annual average to establish baseline production

    Revise the calibrated model to simulate upgraded plant conditions and run over period of record to establish production of upgraded facility

    Compare average annual production of upgraded facility to baseline production

    II. CONDUIT ENERGY MODEL FOR USE WITH CONDUITS ONLY

    Numerical, Excel-based daily dispatch model (capture the difference in flows: weekdays, weekends & holidays)

    Daily flow data for period of record of the conduit o Develop trend line of average daily flow to help identify long term changes in conduit

    usage Head/flow relationship Equipment parameters

    o Flow range o Equipment efficiencies o Headlosses as a function of flow

    Calibration, hand calculations to verify and check model results

    Instructions for Completing Feasibility Budget Form

    Each application must contain a detailed budget (cost proposal), identifying all Allowable Expenses associated with activities required to achieve project goals. Expenses not identified in the budget may not be eligible for subsequent reimbursement. MassCEC reserves the right to reject any application without further review if the budget is not prepared in compliance with the following instructions.

    GENERAL INSTRUCTIONS

    1. The budget must be completed using MassCEC's Standard Feasibility Budget Form (an Excel workbook) and should be submitted as a functional Excel file.

    2. Indicate in the top portion of the form the Applicant's name, the facility name, and a brief descriptive title of the proposed project (e.g., Trash rack replacement feasibility study).

    3. White and green cells are entry cells; yellow cells are calculation cells. In general, do not edit yellow cells unless entering lump-sum costs for services.

    4. Do not include any expenses that may be incurred prior to the award of a grant by MassCEC, as they will not be eligible for reimbursement.

    All budget information must be described in reasonable detail. Use the Supporting Schedule tab in the Excel file to provide detail on budget items (e.g., explanation of labor rate escalation; proposed vendor, quantity needed, unit cost, basis for cost for Direct Materials). Each of the instruction sections below corresponds to a section of the budget form.

    SECTION A: DIRECT LABOR AND RELATEDPARTY LABOR

    This section is for project costs related to labor performed by employees of the Applicant or employees of Related Parties (see Solicitation for definition of Related Party). The individuals, categories, or types of labor shown on this worksheet should correspond with the team described in the Application.

    1. List each task or role and the individual, or type of labor category (e.g., Senior Engineer, Geologist) that will be required to complete the task. Identify employees of related parties, where applicable.

    2. Indicate the number of hours expected of each individual, category, or type of labor. 3. Enter the actual labor rate for each individual, category, or type of labor. Labor must be valued at

    fair market value. Hourly rates may include gross wages, Employers Responsibility Federal Insurance Contributions Act (ER FICA) taxes, Employers Responsibility Medicare taxes, State Unemployment Insurance (SUI), and Federal Unemployment Tax Act (FUTA) taxes. Hourly rates should not include fringe benefits, other overhead expenses, or a profit margin.

    4. If an escalation in labor rates is anticipated, enter additional lines for the labor to be worked at the higher rates.

    5. Direct and Related-Party Labor is limited to a combined 50% of total project costs for Feasibility Study Grants. Note that this percentage will be auto-calculated in the Budget Summary section.

    Note: If audited, Grantee may be required to provide MassCEC with a copy of the payroll register which coincides with direct labor paid. It should include the title or labor category, and the hourly rate, for each employee who worked on the project.

    SECTION B: CONTRACTORS/CONSULTANT

    This section is for project costs related to project services provided to the Applicant on a contract basis by individuals, organizations or companies who are contractors or consultants to the Applicant.

    1. List each task or role and the individual, or type of labor category (e.g., Senior Engineer, Geologist) that will be required to complete the task.

    2. Enter the contractor/consultant quoted or anticipated rate per hour and number of hours for each consultant. If no quoted rate is available, or if the contractor/consultant has proposed a lump sum for the service, enter the lump sum or estimated total cost of the service in the last column (yellow cell).

    3. No more than 20% of th
