Energy service in St. George works a little differently than in many other cities. Instead of a single statewide utility serving every home, Washington County is served by a mix of municipal power departments, a member-owned electric cooperative, wholesale power agencies, natural gas utilities, and propane suppliers. Which provider you use often depends on exactly where you live.
Understanding these suppliers helps residents and businesses plan for service, compare options, and make informed energy decisions. This guide highlights ten energy suppliers that power St. George and the surrounding communities.
How Energy Service Works in St. George
For electricity, the City of St. George Energy Services Department serves much of the city north of the Virgin River, while Dixie Power serves many areas south of the river. Nearby cities such as Washington, Hurricane, and Santa Clara operate their own municipal power departments.
Natural gas is delivered by Enbridge, while propane suppliers serve areas without natural gas lines. Behind the scenes, wholesale suppliers provide the power that local utilities distribute to customers.
