WGL Holdings history

In 1878, Thomas Edison introduced the incandescent lamp, a threat to the company.

In 1891, one of the gasometers exploded; the cause was attributed to a large storm.

Gas furnaces began to appear in 1915.

In 1947, the gas industry expanded to nearly 22 million customers nationwide.

In 1964, the Washington Gas Light Company sold development rights for the location in a deal that stipulated that the new structure would be supplied exclusively by the company.

In 1988, WGESystems (now WGL Energy) is organized as a division and subsidiary of Washington Gas, dedicated to energy conservation and providing renewable energy solutions such as solar power.

In 1997, in response to newly deregulated gas and energy markets, Washington Gas formed Washington Gas Resources Corp to serve as a holding company for non-utility subsidiaries.

In 2004, WGL added its one millionth energy customer.

WGL Holdings Chairman Terry McCallister rings the closing bell at the New York Stock Exchange in 2010 to celebrate the company’s 70th anniversary on the exchange.

WGL is honored by the Salvation Army in 2014 for its 30-year commitment to providing energy benefits to the Washington D.C. community through the Washington Area Fuel Fund.
