Duke Energy Corp.'s 600,000 customers in South Carolina will soon see their bills go up.
The South Carolina Public Service Commission on Wednesday accepted the utility's request to increase overall rates by 6 percent.
Residential rates will go up about 7 percent, or about an additional $6 a month on typical bills. Commercial and industrial rates will increase about 5 percent.
In November, Duke cut its increase request from 15 percent. The Charlotte, N.C.-based utility has agreed to donate $4 million to AdvanceSC, which the utility created in 2004 to distribute grants for economic development and low-income assistance.
Customers had protested the increase, Duke's second in South Carolina since 2010. Duke plans to seek a third increase this year as it continues to pay for new power plants.
