On January 31, 2020, Bay State Gas Company d/b/a Columbia Gas of Massachusetts (“Company”) filed a petition with the Department of Public Utilities (“Department”) for approval of its revenue decoupling adjustment factors (“RDAFs”), for effect May 1, 2020. This filing was made pursuant to: Bay State Gas Company, D.P.U. 15-50 (2016); Reduction in Federal Income Tax Rates, D.P.U. 18-15-A (2018); and the Company’s revenue decoupling adjustment clause (“RDAC”) tariff, M.D.P.U. No. 285A. The RDAC allows the Company to modify, on a semi-annual basis, its base distribution rates as a result of changes in customer usage, in order to promote the efficient deployment of demand resources. Bay State Gas Company, D.P.U. 09-30, at 25-26, 87 (2009). The Department has docketed this petition as D.P.U. 20-10.
