Undated (KELO-AM) MidAmerican Energy is seeking rate increases for natural gas and electric customers in South Dakota.
MidAmerican Spokeswoman Ruth Comer says its been ten years since the company has asked for a gas rate increase and 20 years for electric.
Comer says the average monthly gas bill would increase $1, while electric customers would pay an additional $9.65 a month. She says customers will be advised of the proposed changes with their bills.
The South Dakota Public Service Commission has six months to review and approve the proposals.
MidAmerican serves about 88,000 gas customers and about 4,600 electric customers in South Dakota.
