Tacoma Power commercial electricity prices, 2015 to 2025

In 2015 Tacoma Power billed its commercial customers an average of 8.31¢ per kWh. In 2025 the figure was 10.65¢, so it rose 28% over 10 years. The average for all commercial customers in Washington rose 33% over the same period. The latest year, 2025, is the highest of the 11 on record here. Between 2024 and 2025 it rose 3.4%.

Average use and average bill are the utility’s commercial sales and revenue divided by its commercial customers and by twelve. The bill is an all-in figure: energy, delivery, demand and fixed charges together. A few very large customers pull both averages up, so most businesses use and pay less than the average.

Residential, commercial and industrial prices at Tacoma Power

In 2025 the average commercial price at Tacoma Power was 7.0% below the residential figure and 36% above the industrial one. Larger customers take power at a higher voltage and use it more steadily, so at most utilities the average falls from residential to commercial to industrial. Which class an account falls in is the utility’s decision, and the line between commercial and industrial is drawn differently from one utility to the next.

How Tacoma Power’s commercial rates are set

Tacoma Power is owned by the community it serves. Its rates are set locally, by the city council or a utility board, and in most states the state commission does not set them. A commercial account is billed on a rate schedule, chosen by the size of the account and the voltage it takes power at, and a schedule usually combines a fixed monthly charge, a charge per kWh and, above a certain size, a demand charge on the highest rate of draw in the month. The schedule code is printed on the bill. There is no competitive supply market for ordinary commercial accounts in Washington, so the levers are the schedule, the peak and the amount used.

Meters, time-varying rates and net metering at Tacoma Power

EIA counts 19,574 commercial meters at Tacoma Power in 2025 and reports no advanced (AMI) meters among them. Of those, 19,574 are standard meters. Without an advanced meter a business generally has no interval data, so its peak demand is read from the meter’s own register.

EIA records 81 commercial net-metered generating systems at Tacoma Power in 2025, with 1.89 MW of capacity between them: about 4.0 for every 1,000 commercial customers. Net metering credits a customer for power its own system sends to the grid; the terms are in the utility’s tariff.

How reliable is Tacoma Power’s electric service?

Tacoma Power customers went without power for an average of 70 minutes in 2025, excluding major storms, with about 0.68 interruptions per customer. The average across U.S. utilities reporting the same way is 124 minutes. With major storms counted the figure was 172 minutes. These are averages over every customer of every class, so they describe the system and not any one street.

Where Tacoma Power serves

EIA records Tacoma Power serving customers in 4 Washington counties: King, Lewis, Mason, Pierce. A county can be shared between utilities, so this does not tell you who serves a given address. The utility that serves an address is the one named on its bill.

EIA lists Tacoma Power as its balancing authority, the body that keeps supply and demand matched minute by minute across the area.

Other utilities in Washington

The average each billed its commercial customers in 2025. The Washington page has the state’s own figures and every utility with 500 or more commercial customers.

• Puget Sound Energy (15.66¢)
• Seattle City Light (12.48¢)
• Snohomish County PUD (9.90¢)
• Avista (14.30¢)
• Clark Public Utilities (8.76¢)
• Pacific Power (13.21¢)

What these figures can and cannot tell you

• They are averages over every commercial customer. A utility whose commercial customers are mostly large averages fewer cents per kWh than one serving mostly small shops, so a lower figure can mean larger customers and not a lower rate.
• They are not a rate schedule. None of these figures is a charge printed in Tacoma Power’s tariff, and nothing here works out a bill from one. The tariff index lists the utilities whose filed schedules are quoted on this site.
• They are annual and final. EIA publishes utility figures once a year. The Washington page carries the state’s trailing 12 months, which is more recent and still preliminary.

For one building, the cost estimator gives a range by building type, size and state, and price by utility sets every utility side by side. Commercial vs residential vs industrial compares the classes in every state.
