Evaluation of LIPA’s Efficiency Long Island & Renewable Technology Programs Presented to: LIPA Board of Trustees By: Bill Norton Chief Operating Officer – Opinion Dynamics Corp. June 27, 2013

1 Agenda Review of Evaluated Results for 2012 Program Year Review Portfolio Level Results (ELI and Renewable Energy) ► Impacts, Cost Effectiveness, Economic and Environmental Benefits Review Program Level Results ► Impacts, Cost Effectiveness, Economic and Environmental Benefits Summary

2 Evaluation Overview This is the fourth evaluation cycle completed by the Opinion Dynamics Evaluation Team – findings reflect 2012 program year activities Impact evaluation is similar in scope to 2011 – produced evaluated demand and energy savings and cost effectiveness results. Cumulative evaluated results for 2009, 2010 and 2011 were 87.2 MW and 432,274 MWh from ELI and 13.2 MW and 32,859 MWh from Renewable portfolio. The evaluation again found that ELI and Renewable Energy programs are delivered in a cost effective manner. The evaluated demand and energy savings from all ELI and Renewable programs in 2012 was MW and 257,012 MWh (93% of demand goal and 97% of energy goal, while spending 86% of budget).

3 Evaluation Overview (continued) The evaluation team updated the economic Input-Output (I-O) model of the Long Island regional economy, developed by the team in 2011, and its inputs to estimate economic impacts attributable to LIPA’s investment ELI and Renewable energy programs  LIPA’s investment in ELI and renewable energy programs in 2012 yielded a combined $87M in total economic benefits to the regional economy, including employment benefits of 646 FTEs  Economic benefits inclusive of the direct benefits of LIPA’s investment  FTEs are one year benefits

Efficiency Long Island Program Achievements in 2012 Processed over 4,000 commercial applications Completed 171 energy efficiency projects in over 150 schools, totaling nearly $5 million in rebates Recycled over 9,700 refrigerators Rebated over 24,000 Energy Star refrigerators Continued rebating compact fluorescent lamps while making transition to encourage the installation of 250,000 residential LED lights Received Awards ► Sustainable Excellence for Home Performance with Energy Star ► Green Classroom High Performance Learning Partner Award ► Smart Growth Award for Clean Energy Programs ► Award from the Long Island Chapter of the US Green Building Council 4

Efficiency Long Island Program Achievements in 2012 (cont.) Achieved 93% of energy efficiency goal despite the impact of Superstorm Sandy peak demand savings of 51.3 MW was 50% higher than Evaluated results are consistent with program tracking data provided to the board in January as program planning estimates and tracking data are in close alignment. Efficiency Long Island is now beyond the ramp-up phase and reaching full potential. Solution Provider (TRC) and Small Business Direct Install Contractor (LIME Energy) are now at full strength and meeting 2013 goals. 5

8 ELI Portfolio - Benefit/Cost & Levelized Cost 2012 results indicate that all program efforts are cost effective from LIPA perspective compared to supply alternatives (B/C >1). The 2012 levelized cost results for ELI programs compare favorably to LIPA’s marginal cost of generation at the portfolio and segment (residential and commercial) level. Program Program Administrator (B/C) * Levelized Cost ($/kW-yr) Capacity * Levelized Cost ($/kWh) Energy * Commercial3.1$190.76$0.047 Efficient Products (EEP)4.2$162.65$0.023 Existing Residential1.4$312.51$0.220 Residential with EEP2.7$213.73$0.044 ELI Portfolio2.9$199.39$0.046 * Evaluated results – using 5.643% nominal discount rate

9 ELI Portfolio – Environmental Benefits Evaluated demand and energy savings attributable to the 2012 ELI portfolio equate to environmental benefits ► Displacement of 154,500 tons of carbon dioxide ► Displacement of 536 tons of sulfur dioxide ► Displacement of 166 tons of nitrous oxides Equivalent to removing roughly 26,000 cars from the road and fuel savings of more than 326,000 barrels of oil Since inception in 2009, evaluated ELI savings equate to: ► Displacement of roughly 427,500 tons of carbon dioxide ► Displacement of roughly 1,486 tons of sulfur dioxide ► Displacement of roughly 461 tons of nitrous oxides

10 Renewable Portfolio Evaluated MW and MWh Impacts

11 Renewable Portfolio Benefit/Cost & Levelized Cost 2012 levelized cost (excluding net-metering costs) is $0.126 per kWh, and costs for solar are trending down.

12 Renewable Portfolio – Environmental Benefits Evaluated demand and energy savings attributable to the 2012 Renewable portfolio equate to environmental benefits ► Displacement of more than 7,500 tons of carbon dioxide ► Displacement of nearly 13 tons of sulfur dioxide ► Displacement of nearly 8 tons of nitrous oxides Equivalent to removing roughly 1,200 cars from the road and fuel savings of more than 16,000 barrels of oil Since 2009, Renewable program savings equate to: ► Displacement of 26,500 tons of carbon dioxide ► Displacement of 43 tons of sulfur dioxide ► Displacement of 28 tons of nitrous oxides

Evaluated Results – Economic Impacts ELI ► 2012 First Year Impacts: LIPA’s $75M investment returned $82M in economic benefits to the regional economy, including 609 new FTEs ► Year Impacts: LIPA’s 2012 investment will continue to accrue benefits through customer bill savings Over 10 years, 2012 investment expected to return $142M (in 2012 $) in economic benefits, including 1,086 new FTEs Renewable Energy Programs ► 2012 First Year Impacts: LIPA’s $21M investment returned $5M in economic benefits to the regional economy, including 37 new FTEs ► Year Impacts: Over 10 years, 2012 investment expected to return $13M (in 2012 $) in economic benefits, including 101 new FTEs

Conclusions Opinion Dynamics has evaluated LIPA’s Efficiency Long Island (ELI), and Renewable Programs for the past four years. Programs are well managed and results have increased substantially in recent years with ELI achieving a cumulative 138 MW through LIPA has leveraged evaluation results to improve program design and operations. Programs are cost effective with an overall benefit/cost ratio of nearly 3.0 Programs yield positive impacts on the Long Island economy and environmental benefits. 16
