• Measure Data Collection Background • Measure Detail – Summary • Measure Detail - State Level • Measure Detail – Focus on • Energy, Demand, and Cost by Measure

ISO-NE PUBLIC 2 Disclaimer • This presentation and data representation are not intended to be used as cost effectiveness tests for Energy efficiency programs. The ISO has no position regarding cost effectiveness. • Measure data is sourced from Program Administrator submissions over the past energy efficiency Forecast data collection cycles. • The dataset is not complete, particularly in the area of dollars spent per measure type. Therefore, analysis is only presented where complete data are available. • All assumptions and conclusions from these representations are preliminary and for informational purpose only.

ISO-NE PUBLIC 3 Background on Measure Data • 2012 Forecast – PA data collection process included request to report the measures in each program for 2008-2010, where available. • 2013 Forecast – PA data collection process included a request to report the relative percentage of energy savings for the 10 top measures in each program year 2011, where available. • 2014 Forecast – PA data collection process included a request to report the relative percentages of energy savings, demand savings, and dollars spent for the 10 top measures in each program for years 2008 – 2012, where available. • 2015-2021 Forecasts – PA measure data collection request the same as 2014 forecast.
