EIA lists a utility in a county when it has customers anywhere in it, so this is everyone with a presence, ordered by commercial customers across California, not a statement about any one address.

What businesses in Ontario pay
Across California, businesses paid an average 27.00¢ per kWh over the 12 months to August 2026, 94.7% above the U.S. average of 13.87¢, and up 5.4% on the 12 months before. That ranks California 2 of 51, where 1 is the highest price. In 2025 the average commercial account in the state used 5,360 kWh a month, about $1,402 a month at the state price; that is a mean pulled up by a few very large users, so most small businesses use less.
A city has no price of its own: two businesses on the same street can pay very different amounts per kWh, because the rate schedule, the size of the peak and, where it is allowed, the supply contract matter more than the location. The California page has the state’s price history since 2010 and every utility with at least 500 commercial customers.
Choosing a supplier in Ontario
California is not an ordinary retail choice market. Direct Access is capped and administered by allocation, and Community Choice Aggregation is determined by location rather than by shopping. For most commercial accounts the controllable cost sits in rate schedule selection, time-of-use windows and demand charges.
Where prices are heading
EIA does not forecast single states. For the Pacific census division, which includes California, its November 2026 Short-Term Energy Outlook puts the average commercial price at 21.53¢ per kWh for 2026 and 22.11¢ for 2027, up 7.5% from 20.56¢ in 2025. The forecast for every region.

Common questions
- Who provides electricity to businesses in Ontario?
- EIA lists Southern California Edison, PG&E, City of Colton and Bear Valley Electric Service and 7 more as electric utilities in San Bernardino County. Which one serves a given address depends on the street; the utility on an existing bill is the definitive answer, and a utility can confirm service for a new site.
- What is the average commercial electricity rate in Ontario?
- There is no official figure for a city. EIA publishes prices by state and by utility: Southern California Edison averaged 22.94¢ per kWh for its commercial customers in 2025, and California averaged 27.00¢ over the 12 months to August 2026. A business’s own price depends on its rate schedule, its demand and, where it can choose, its supply contract.
- Can a business in Ontario choose its electricity supplier?
- California is not an ordinary retail choice market. Direct Access is capped and administered by allocation, and Community Choice Aggregation is determined by location rather than by shopping. For most commercial accounts the controllable cost sits in rate schedule selection, time-of-use windows and demand charges. The state page for California explains how it works and who regulates it.
Averages describe Ontario; a bill describes your business. A person can read yours: rate schedule, demand, riders, contract window. Nobody calls unless you ask.
