MASSACHUSETTS: A GREAT CLEAN ENERGY STORY—DERs AND THE NEXT CHAPTER 3 51ST STATE PERSPECTIVES Executive Summary The Commonwealth of Massachusetts has long better understand their location and behavior on been a leader in the deployment of clean energy. the grid. It was an early adopter of a renewable portfolio Beyond retail deregulation, the emergence of DERs standard (RPS) and energy efficiency targets. has not significantly altered the utility business Massachusetts currently has an RPS for “all retail model in Massachusetts. NEM has been in place electric suppliers” of 15% by 2020 and 25% by since 1982 with high levels of enrollment, and the 2030. Eversource Massachusetts and National Commonwealth has seen the same challenges Grid Massachusetts both achieved more than with NEM as have emerged elsewhere in terms of 3% savings through energy efficiency programs appropriate compensation for excess generation 1 as a percentage of their retail sales in 2016. and utility delivery charges. Massachusetts The Commonwealth has a significant penetration continues to operate under traditional cost of of distributed generation and robust enrollment in service ratemaking; however, some innovative net energy metering (NEM) programs. In addition, it proposals were approved in the recent Eversource has a target for electric vehicles (EVs) of 300,000, or rate case, including changes to NEM and approval 15%, of all registered vehicles by 2020. The state’s of performance-based ratemaking (PBR). target for storage is 200 megawatt hours (MWh), also by 2020, supported by additional programs The Commonwealth opened a proceeding on grid and funding. Massachusetts has focused on the modernization in 2014, and the utilities filed grid reduction of greenhouse gas (GHG) emissions, modernization plans in 2015. In May 2018, the and this is reflected in the various programs Massachusetts Department of Public Utilities (DPU) implemented during the last 30 years. issued an order that approved utility proposals for grid-focused upgrades but not advanced The Commonwealth went through retail metering infrastructure (AMI). Grid modernization deregulation in 1997, leaving the investor-owned investments will enhance automation and visibility utilities as wires-only businesses.
