Similar to last year’s impact evaluation, the 2017 Self-Generation Incentive Program (SGIP) Storage Impact Evaluation finds that, in general, SGIP storage projects, while successful at reducing system peak demand, system costs and customer demand overall, continue to result in a net increase in greenhouse gas (GHG) emissions and fall short of the efficiency goals of the program. These results are somewhat to be expected, as the main driver of this behavior — misalignment between retail rates and grid needs — has not materially changed between the two evaluation periods (2016 and 2017).
