OEC rate expert breaks down Power Cost Adjustment

Many factors can contribute to fluctuations in electric bills. The first, and most obvious, is the weather. We expect our electric bills to be reflective of the different seasons and the changes in routine each one brings. Other events, such as adding members to our household, a leaking water well or the addition of a pool, can cause an increase in costs as well. But what happens when our bills are noticeably higher when we've made no sizable changes? The answer can likely be found in the Cost Adjustment.

What is a cost adjustment?

"Rather than generating our own power, OEC purchases the power at wholesale cost and delivers it safely to members' homes and businesses," said Key Accounts and Advocacy Specialist and rate expert Tim Ferree. "The Cost Adjustment is a separate line-item on each bill that reflects the increases and decreases of the power we purchase from Western Farmers Electric Cooperative (WFEC)." 5507115302

Why does the cost adjustment fluctuate?

The fluctuation in the Cost Adjustment is caused by changes in the cost of fuel for electric generation, mainly natural gas. Natural gas prices were above $9 in 2022, $2.13 last August. It is currently around $3 per MMBtu, but has been over $4 most of 2025.

A portion of OEC’s cost of power is already included in the energy charge, or kilowatt hour (kWh) charge. When the cost of power is greater than the amount included in the energy charge, the Cost Adjustment reflects that increase. When the cost of power purchased is less, the Cost Adjustment appears as a credit on electric bills.

Who is affected by the cost adjustment?

For about a three years now, the electric industry has experienced record highs in the cost of generating electricity.

These increases are caused mostly by the record high natural gas prices but supply and demand, the economy, seasons and weather, storage costs or alternative energy cost shifts play a role.

Essentially, all electric consumers are affected by these events and are experiencing increases in their costs of power.

"Despite these hardships, WFEC is a leader in the integration of renewable energy that benefits all OEC members," said Ferree. "WFEC has been able to maintain a reliable supply of wholesale electric service across their region. They understand the importance of a diverse portfolio of resources in today's energy market."

OEC prices remain below the national average price of electricity, and we continually work with WFEC to ensure that remains the case.

What can I do in the meantime?
