Fixed versus variable business energy rates

What a fixed rate actually fixes

Check the term, price unit, included services, and exceptions. A fixed energy price can leave capacity, transmission, ancillary services, gas basis, or delivery charges outside its scope. Even a broad fixed supply product still multiplies price by actual consumption and can contain provisions for extraordinary changes. Ask for the specific clauses that permit repricing. If a salesperson says everything is fixed, require the executed agreement to define precisely what that means for your account.

How variable pricing differs from an index

A variable price may reset monthly according to the supplier’s stated discretion or formula. An indexed product instead identifies a market reference and settlement method, though it can have variable adders. Do not assume those structures are identical. Request a sample calculation, historical reset information where available, and the method for communicating future changes. Watch for an introductory fixed period that converts to a variable holdover price, especially if renewal notices go to a former employee.

Compare risk as well as expected cost

Fixed pricing trades exposure to some future market increases for the obligation to pay the agreed price if markets decline. Variable pricing retains more upside and downside depending on the formula. Model a high-cost month and consider liquidity, not just a favorable average case. A business with thin operating margins may place a higher value on predictable defined costs. Termination fees, monthly fees, and usage restrictions can also overturn a small headline price advantage.

Hypothetical bill sensitivity

At 30,000 kWh, a hypothetical fixed supply rate of $0.085/kWh gives $2,550 before other charges. A variable price of $0.075/kWh gives $2,250, while $0.115/kWh gives $3,450. That is a $900 increase over the fixed example in the high-price month. If consumption rises at the same time, the dollar exposure grows further. These values are scenarios rather than forecasts. Include all product fees and unpriced components before presenting an annual comparison.

Practical review checklist

• List fixed components and every contractual adjustment exception before approving the quoted rate.
• Identify variable reset frequency, reference index if any, notice method, and post-term pricing.
• Test combined high-price and high-usage periods against available cash and budget limits.
• Compare cancellation and renewal obligations as carefully as the initial supply price.
