1 Case Study: DR at Defense Intelligence Agency Gregg Dixon, SVP, EnerNOC Jonathan Crittenden, Mechanical Engineer, PE, Defense Intelligence Agency July 14, 2009

2 EnerNOC Overview Founded in 2001, EnerNOC is the largest demand response (DR) provider focused exclusively on the commercial and industrial sector. BILATERAL CONTRACTS – REGULATED UTILITIES Burlington Electric Department (VT) 10 MW, 4 year contract Idaho Power 65 MW, 5 year contract Maryland IOUs Allegheny Power, Baltimore Gas & Electric, Delmarva Power, Pepco 250 MW, 4 year contracts Pacific Gas & Electric 40 MW, 5 year contract Public Service Company of New Mexico 30 MW, 10 year contract Puget Sound Energy Pilot Program, 2 year contract Salt River Project 50 MW, 3 year contract San Diego Gas & Electric 25 MW, 10 year contract 25 MW expansion (pending regulatory approval) Southern California Edison 40 MW, 2 year contract 110 MW extension (pending regulatory approval) Tampa Electric Company 35 MW, 4 year contract Tennessee Valley Authority 110 MW, 3 year contract Xcel Energy (Colorado) 44 MW, 8 year contract ISO-New England (ISO-NE) PJM Interconnection (PJM) New York ISO (NYISO) Ontario Power Authority (OPA) Electric Reliability Council of Texas (ERCOT) PROGRAMS IN RESTRUCTURED MARKETS

3 Demand Response and the Federal Government

4 Demand Response Annual Energy Demand 50% 100% WinterSpringSummerFall 75% 90% 25%

5 Demand Response benefits EconomicOperational Reliability Community

6 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.

7 GSAs 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.

8 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. Larry Fratis, Head of the Electricity Branch for DESC Representative Federal / Military DR Customers (totaling 55 MW): Pentagon National Reconnaissance Office US Naval Academy Fort Detrick, MD Fort Belvoir, VA Defense Intelligence Agency National Maritime Intelligence Center US Navy Weapons Station, VA USMC Henderson Hall, VA Fort Totten, NY General Services Administration Department of Transportation

9 Demand Response at Defense Intelligence Agency

10 Demand Response – DIA Motivation Greening Initiative Goals Reduce 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.

11 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.

12 Participating in DR program provides economic benefit while helping DIA meet initiative goals Case Study: Defense Intelligence Administration DR DR Supports Greening DIA Initiative By contributing toward grid stability, DIA participation in demand response supports over-arching goals of energy independence and natural resource conservation. Location Washington, DC Program EnerNOC Demand Response / PJM DR Strategy Curtailment only Curtailment Strategies Air handler temperature and fan speed changes VAV units Lighting changes Shut down redundant elevators Shut down other non-essential processes
