Fixed, Variable, And Firm Energy Rates

Rate labels matter. A fixed plan, variable plan, firm product, introductory term, or pass-through provision can change the risk a customer accepts.

Evidence boundary

Plan labels vary; confirm current terms and rules. Educational context is not legal advice or live pricing.

Key takeaways

  • Fixed and variable labels should match the contract language, not just the sales headline.
  • Pass-through clauses, change-in-law language, and introductory terms can affect customer risk.
  • Commercial customers should review product structure with the actual contract and current state rules.

Why plan labels need context

Contract labels can be shaped by state rules and supplier documents, so a label alone is not enough to evaluate a plan.

Read the current plan terms and official guidance instead of relying on an older supplier announcement or a generic definition.

The labels to slow down on

  • Fixed: confirm whether the rate is fixed for the whole term and whether exceptions exist.
  • Variable: understand how and when the rate can change.
  • Introductory: check what happens after the intro period ends.
  • Firm or firm variable: review the exact state and supplier definition before relying on the label.
  • Pass-through or change-in-law: ask what charges can move through to the customer.

The practical review

A good plan review should look beyond the headline rate. It should capture the term, early termination fee, monthly fee, renewal treatment, product label, source date, plan documents, and the customer's current default-service benchmark.

For business accounts, a thorough review also captures usage, demand, rate class, contract end date, and whether the customer needs a custom quote rather than a simple online plan.

Direct answers

What is a fixed energy rate?

A fixed energy rate generally means the supply rate is intended to stay the same for a stated term. The contract still needs review for fees, exceptions, pass-through provisions, change-in-law language, and what happens after the term ends.

What is a variable energy rate?

A variable rate can change under the plan terms. The customer should understand how often it can change, what drives the change, whether notice is required, and whether there is a cancellation fee.
