What you need to know

The PCA is a per-kWh rate that represents changes in the base power cost. It allows increases and decreases in the wholesale power price to be passed through to our members on a more frequent basis.


You know you pay for the energy you use, but what are all those other items on your bill? Our Understanding Your Bill series helps break it down.

Power cost adjustment (PCA)

As a not-for-profit cooperative, we don't collect margins on certain costs. Instead, we pass them through directly to our members. One of these is the base power cost, which is the per-kilowatt-hour (kWh) wholesale price of the electricity we deliver to you.

However, markets fluctuate. Instead of changing our base power cost throughout the year in response to minor dips and rises, those differences are reflected in the Power Cost Adjustment line item on your bill, which can be a positive or negative rate.
