Washington Gas

What Washington Gas does

Washington Gas Light Company is a regulated natural gas utility founded in 1848 and headquartered in Washington, D.C., serving more than 1.2 million residential, commercial, industrial, builder, and government customers across the District of Columbia, Maryland, and Virginia. The company operates as a local distribution company (LDC) under franchise agreements approved by three state public utility commissions (DC PSC, Maryland PSC, Virginia SCC), with rates set through regulated tariff proceedings. Its core product is natural gas delivery through a company-owned underground pipeline network that provides heating, cooking, water heating, and other energy services to end-users, with the company positioning its infrastructure as an independent alternative to congested electric grids—an increasingly relevant value proposition as data center load grows in the DMV region.

The business model is subscription/recurring revenue under regulated tariffs, with revenue recovered through base rates approved by regulatory commissions. Customer-facing infrastructure includes the MyAccount online portal, the My Washington Gas mobile app (iOS/Android), AutoPay, eBill paperless billing, a Budget Plan averaging program, and SMS text alerts. The company complements its core utility service with rebate programs (Washington Gas Rebates via WG Smart Savings), builder incentives (Multifamily Incentive Program), home repair plans via HomeServe partnership, and customer assistance programs (Washington Gas Cares, Washington Area Fuel Fund). Capital allocation is overseen by a dedicated SVP of Capital Delivery across the Mid-Atlantic. Washington Gas is an indirect, wholly-owned subsidiary of AltaGas Ltd. (a publicly traded Canadian energy infrastructure company), through the WGL Holdings, Inc. holding company, which also owns WGL Energy (competitive energy retail) and Hampshire Gas (natural gas storage serving Washington Gas).
