Federal Government Sites and DR Challenges

• Security is paramount

• Administrative infrastructure– “Red Envelope” vs bill

credits

• Site uptime typically a matter of strategic national importance– As opposed to a more straight forward ‘business decision’ in other

settings

• Integration across buildings, campuses, EMS systems, etc.

GSA’s National Security Guidance for Federal Agencies and Federal Building Operators

Public Utility Service Emergency Planning and Operations

• Code 1 – “Normal Operations.” As implied, at this level the building can be run normally.

• Code 2 – “High Demand Possible.” This means the regional power grid is expecting a higher than normal load.

• Code 3 – “High Demand Warning.” When this alert is received, low-impact curtailments should be implemented, i.e., measures that have been identified as having minimal effect on the tenants.

• Code 4 – “Demand Curtailment.” At this stage, building load reductions should be implemented. Tenants should be notified and asked for their cooperation.

• Code 5 – “Maximum Effort.” At this level, building operators and their tenants should be doing everything possible to reduce electric load, particularly in the afternoons.

DESC and Demand Response

DESC encourages federal and military installations to do their part to use energy

more efficiently, and demand response programs are a great way to meet that

objective.

Demand Response at Defense Intelligence Agency

Demand Response – DIA Motivation

Greening Initiative GoalsReduce energy intensity by 5,000 BTU/SF annually (2.5%)

Reduce water intensity by 2.0 GAL/SF (2,500 KGAL) by FY2010

Reduce greenhouse gas emissions by 5,000 MTCE by FY2013

Quadruple recycling by increasing FY2010 output to 100 tons

“Greening DIA” Initiative - Internal program implemented to support the long-term cause of energy independence and natural resource conservation by increasing energy efficiency of enterprise operations.

Demand Response – DIA Experience

• Challenges– Secure, mission-driven 24x365

facility

– Multiple EMCS vendors

– Reliant on local authorities for DC ELRP rules of engagement (air permitting)

– Real-time monitoring

• Process– DIA reviewed multiple DESC compliant vendors across selection

criteria (Fall 2008) before choosing EnerNOC (Jan 2009).

– Multiple follow up meetings with EnerNOC personnel to scope curtailment strategies and work through potential challenges.

Participating in DR program provides economic benefit while helping DIA meet initiative goals
