Questar is no more.

The company that provides natural-gas service to more than 1 million customers in Utah and parts of Wyoming and Idaho officially became Dominion Energy on Monday.

Over the weekend, a sign reflecting the new name was hoisted into place high on the south-facing wall of company headquarters at 333 S. State, readily visible to northbound traffic on State Street.

The name first will appear on customers' bills in July, said Craig Wagstaff, president of Dominion Energy's Salt Lake City-based Western gas operations, although a flier explaining the change will be tucked into June bills.

"Changing our name to Dominion Energy more closely describes our purpose in the communities where we live and work. … The name reflects the business we're in — energy," he added. "One thing that's not going to change is our commitment to you."
