Berkshire Gas Forecast and Supply Plan
In 2014-2015, Berkshire Gas in Massachusetts placed a moratorium on new services in part of its territory after identifying distribution capacity constraints and insufficient supply resources. On July 8, 2016, Berkshire Gas filed a petition with the Department of Public Utilities seeking approval of its Long-Range Forecast and Supply Plan (F&SL) under D.P.U. 16-103. The company based its plan on analysis of various resource options to increase access to natural gas for the region as a precursor to lifting the moratorium.
On behalf of the Town of Montague, Synapse reviewed and assessed the reasonableness of Berkshire Gas’s F&SL. Our review of the resource plan revealed that while the plan included energy efficiency and demand response as options, it gave little attention to such resources. Instead, the company recommended investment in extensive and expensive new infrastructure options. We concluded that the company could lift the moratorium by implementing a few simple steps: (a) re-establish curtailable agreements with two large customers that already have dual-fuel capability, and (b) change the way it estimates impacts from current and future energy efficiency programs. We also identified additional demand-side resource potential by analyzing the historical performance of gas energy efficiency programs in New England, current program offerings, and a new gas demand-response program based on internet-connected thermostats. Our analysis concluded that with these expanded demand-side resources, the company could expect future peak load to decline from today’s level over the next five years. Furthermore, the future load forecast could be even lower if it incorporated potential impacts from emerging technologies and other factors. Specifically, electric heat pumps and the state’s existing climate change policies are highly likely to lead to substantial electrification in various sectors and to lower overall gas consumption.
