2 Regional Context - ISO NE ANNUAL ENERGY USE (GWh) With and without EE and PV Savings SUMMER PEA DEMAND (MW) With and without EE and PV Savings 2

3 Regional Context - ISO NE MW 28,000 26,000 24,000 22,000 20,000 18,000 16,000 14, ISO NE Load Duration Curve 6% of hours represent over 25% of the load The inefficient use of demand has real cost implications Reducing usage during ISO peak demand has two main benefits Reduce ICAP tags Reduce installed capacity requirement More than 4,200 megawatts (MW) will have shut down between 2012 and 2020 an amount equal to almost 15% of the region s current generating capacity Over 5,500 MW of additional oil and coal capacity are at risk for retirement in coming years 12,000 10,000 8,000 0% 3% 6% 9% 13% 16% 19% 22% 25% 28% 31% 34% 38% 41% 44% 47% 50% 53% 56% 59% 63% 66% 69% 72% 75% 78% 81% 85% 88% 91% 94% 97% 3

11 $350 Lessons Learned From Running Both C&I and Residential Programs Work with aggregators in the C&I space Leverage Energy Efficiency Programs Cost per kw per Year $150 $75 Cost control is crucial for residential programs Benefits C&I Program Costs Currently 215 MW Currently 230 Customers Today s Resi Program Costs Currently 2 MW Currently 4,500 Customers Next Year s Resi Program Costs 11

12 Cape Light Compact Municipal aggregator & energy efficiency program administrator (PA) Oldest aggregation in U.S. Comprised of and serves the 21 towns on Cape Cod and Martha s Vineyard 205,000 EE customers 138,000 power supply customers Only non-utility PA in MA

13 CLC s DR Landscape kwh Sales MA law requires acquisition of all costeffective energy efficiency & demand reduction resources Serve mostly residential customers & load Significant amount of seasonal commercial customers/load C&I Residential # Customers Largest percentage of second homes in MA C&I How do we engage residential customers in load management? How do we manage commercial peak load during a short busy season? Residential

14 Residential DR Engaging residential customers in load management: Behavior Initiative Began in 2009, gave participants near-real time usage/demand visibility Participants successfully shifted and reduced load voluntarily using energy insights provided DR Demonstration Offering built on experience from Behavior Initiative to include DLC for air conditioning Wi-Fi thermostats and mini-split controls

15 Small Commercial DR Seasonal businesses are focused on summer customers not summer load Less likely to make behavioral changes or accept DLC that affects operation or customer comfort Storage as DR may be most effective Thermal storage targets A/C Load Exploring battery storage deployment Storage dispatch has no customer-facing impact on operations or comfort Images courtesy of Ice Energy

16 DR beyond 2018 Expand DR Demonstration Offering Leverage growing installed base of Wi-Fi thermostats Deploy additional thermal storage Explore additional load management opportunities/technologies Increasing number of connected devices/appliances present new opportunities for residential engagement/load management Decreasing cost of battery storage may allow for non-disruptive DR for seasonal businesses (and res. customers) Outcome of MA grid modernization proceedings currently under review may provide better tools/incentives for customers to participate in DR
