The city's website, www.eaglemountaincity.com, includes a question-and-answer page, a utility cost-comparison calculator and information about current rates.
When the agreements are finalized, Pengra said the city will cut roughly $26 million in gas and electric bond debt, a reduction of more than 50%. Eagle Mountain would retain about $6 million in gas fund balance and the energy department building.
Questar will pay almost $12 million to acquire the 15-year-old gas system and its 126 miles of lines, said spokesman Darren Shepherd.
It's a good investment, said Craig Wagstaff, executive vice president of Questar Gas, noting Eagle Mountain has 6,000 homes and substantial room to grow. The city is the state's third largest geographically, covering 44 square miles.
"The purchase will provide Questar Gas with operational advantages and a good return on our investment," he said.
Eagle Mountain will shift its electric utility assets to the South Utah Valley district, which is publicly owned and provides power to cities in the county's southern end.
Adding Eagle Mountain strengthens the district by broadening its base, said chairman Blair Hamilton.
