Berkeley Electric Cooperative commercial electricity prices, 2015 to 2025

In 2015 Berkeley Electric Cooperative billed its commercial customers an average of 12.75¢ per kWh. In 2025 the figure was 8.27¢, so it fell 35% over 10 years. The average for all commercial customers in South Carolina rose 9.5% over the same period. The highest year was 2018, at 12.94¢. Between 2024 and 2025 it rose 16%.

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 Berkeley Electric Cooperative

In 2025 the average commercial price at Berkeley Electric Cooperative was 49% below the residential figure and 35% below 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 Berkeley Electric Cooperative’s commercial rates are set

Berkeley Electric Cooperative is a cooperative, owned by the members it serves. Its board sets its rates, and in some states the state commission reviews them as well. 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 South Carolina, so the levers are the schedule, the peak and the amount used.

Meters, time-varying rates and net metering at Berkeley Electric Cooperative

EIA counts 18,847 commercial meters at Berkeley Electric Cooperative in 2025, and 18,847 of them (100%) are advanced meters (AMI), which record use at least hourly and report it to the utility at least daily. An advanced meter is what makes interval data possible, and interval data is what shows when a building’s peak demand happens.

At Berkeley Electric Cooperative, 360 commercial customers were on a time-varying rate in 2025, about 1.9% of its commercial customers. A time-varying rate charges more in some hours than in others, so when a business uses power matters as well as how much. The kinds Berkeley Electric Cooperative reports offering commercial customers are time-of-use pricing.

EIA records 12 commercial net-metered generating systems at Berkeley Electric Cooperative in 2025, with 0.40 MW of capacity between them: about 0.6 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 Berkeley Electric Cooperative’s electric service?

Berkeley Electric Cooperative customers went without power for an average of 93 minutes in 2025, excluding major storms, with about 1.10 interruptions per customer. The average across U.S. utilities reporting the same way is 124 minutes. With major storms counted the figure was 114 minutes. These are averages over every customer of every class, so they describe the system and not any one street.

Where Berkeley Electric Cooperative serves

EIA records Berkeley Electric Cooperative serving customers in 3 South Carolina counties: Berkeley, Charleston, Dorchester. 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 Santee Cooper as its balancing authority, the body that keeps supply and demand matched minute by minute across the area.

Other utilities in South Carolina

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

• Dominion Energy South Carolina (12.90¢)
• Duke Energy Carolinas (9.68¢)
• Duke Energy Progress (11.02¢)
• Santee Cooper (10.82¢)
• Horry Electric Cooperative (14.15¢)
• Palmetto Electric Cooperative (13.56¢)

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 Berkeley Electric Cooperative’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 South Carolina 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.
