And darkness shall have no dominion .... as long as Dominion Resources powers lights across the territory it serves. Dominion is one of the top energy players in the US. Dominion Generation manages regulated and non-regulated power plants. Through its Dominion Virginia Power unit, the company transmits and distributes electricity across 57,300 miles of electric distribution lines to 2.5 million customers, and natural gas to 1.3 million customers.
