If you live in Omaha, you might see utility prices jump in the next month. The Omaha Public Power District is considering a general rate increase of 6.9 percent. It would be the district's biggest rate increase in 10 years. Residential rates would rise 7.7 percent or $7.30 each month. Rates for commercial customers would rise 5 percent and rates for industrial customers would go up 8.5 percent. OPPD spokeswoman Paula Lukowski said Tuesday that OPPD's board is scheduled to discuss the proposal at its meeting Thursday and vote on it Dec. 13. OPPD is a customer-owned utility that serves more than 352,000 customers.
