Washington Gas Light Co.

What Washington Gas Light Co. does

Washington Gas Light Company, founded in 1848 under a Congressional charter signed by President James K. Polk, is a regulated natural gas distribution utility serving more than 1.2 million residential, commercial, industrial, builder, and government customers across the District of Columbia, Maryland, and Virginia. The company is an indirect, wholly-owned subsidiary of AltaGas Ltd. (TSX: ALA), a Canadian energy infrastructure company, with WGL Holdings as the immediate parent. Washington Gas generates revenue primarily through tariff-based rates approved by the DC Public Service Commission, Maryland Public Service Commission, and Virginia State Corporation Commission, charging a fixed customer charge plus volumetric delivery charges (therm-based) under monthly subscription billing. The company runs a sales-led go-to-market for new service connections across residential, commercial, industrial, and builder/contractor segments, with self-service account management via the MyAccount web portal and the My Washington Gas mobile app.

Its product portfolio centers on natural gas distribution, layered with digital customer-service platforms (MyAccount, mobile app), payment and billing tools (AutoPay, eBill, Budget Plan), customer assistance programs (Washington Gas Cares, Washington Area Fuel Fund, Gift of Warmth), energy-efficiency rebates (WG Smart Savings), and infrastructure-modernization programs (District SAFE pipeline replacement, STRIDE in Maryland). Adjacent subsidiaries include WGL Energy (competitive electricity, renewable, and carbon offset retail offerings) and Hampshire Gas (gas storage in West Virginia). The company also pursues non-core initiatives, including a recent entry into data center backup power generation through colocated gas-fired generation agreements and partnerships with hardware retailers and food banks for community engagement. Operations are underpinned by pipeline safety and integrity management programs, a 24/7 emergency response function, and a capital program overseen by dedicated senior executives for capital delivery, regulatory affairs, and government affairs.
