MURRAY — The Murray City Power utility plans to raise its rates by 5 percent beginning in July and another 5 percent in October.

The increase will affect both base customer costs and charges per kilowatt hour. Average homes would end up paying about $3 more monthly during the summer and about $6 more monthly during the fall and winter. The total average bill would be about $64 per month.

Murray officials chose to increase the rates in two tiers to help customers paying high energy costs for air conditioning, said Murray City Power general manager Blaine Haacke.

In coming years, the power company plans regular increases of 3 percent annually. The change is a direct representation of Murray having to pay more for the power it receives, Haacke said.

The Murray City Council held a meeting on the proposed increase Tuesday, but no residents attended. The council is likely to approve the rate changes when it approves the 2008-09 budget in coming weeks.
