Overview
The Public Service Commission of the District of Columbia (DCPSC) is overseeing Formal Case No. 1180, which involves Washington Gas Light Company’s (WGL) application to increase rates and charges for natural gas services in the District. WGL's proposal aims to adjust its revenue to cover the costs of maintaining and upgrading its infrastructure.
Background
WGL submitted an application on August 5, 2024, to increase its total revenue by approximately $257.2 million, which would mean a weather-adjusted annual increase of $45.6 million. This includes $11.7 million from previously approved infrastructure projects known as PROJECTpipes, resulting in an effective net increase of $33.9 million — or roughly an 11.9% increase over current rates. WGL's plan also includes a tool called the Weather Normalization Adjustment that’s designed to even out customer bills during extreme weather fluctuations.
