Every year we do our best to determine at what point to set our rates to meet our estimated costs for electricity. However, changes in member usage or costs of wholesale power from our supplier might result in higher or lower costs to Meeker Cooperative Light and Power Assn.. A Power Cost Adjustment (PCA) is an adjustment in our retail rate schedules that allows the kilowatt hour cost to be raised or lowered slightly without having to request a completely new rate schedule. The PCA rate will fluctuate on your bill each month based on current cost of wholesale power as well as your varying energy usage.
