Petition of Bay State Gas Company, d/b/a Columbia Gas of Massachusetts for approval of its Revenue Decoupling Adjustment Factors for the 2019 Off-Peak Period, May 1, 2019 through October 31, 2019.

On January 30, 2019, 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, 2019.
This filing was made pursuant to Bay State Gas Company, D.P.U. 15-50 (2016) 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. 19-14.

The Company proposes RDAFs of $0.0649 per therm for residential customers,
$0.0589 per therm for low annual commercial and industrial customers (“C&I”), $0.0274 per therm for medium annual C&I customers, $0.0158 per therm for high annual C&I customers, and $0.0080 per therm for extra high annual C&I customers. As a result of the proposed changes to the RDAF, the average residential heating customer using 29 therms per month during the off-peak period will experience a bill increase of $0.38 or 0.87 percent as compared to the previously effective off-peak RDAF. Bay State Gas states that the average monthly bill impact for all rate classes at each class’s average use will range from an increase of 0.59 percent to 1.29 percent as compared to last year’s off-peak period RDAF.  For specific bill impacts, please contact the Company as shown below.
