Fixed vs. Variable Utility Rates: Which to Pick

Sat, 07 Mar 2026 00:00:00 +0000

Quick Answer

A fixed rate locks the supply price for the term; a variable rate follows the market and can change — sometimes monthly. Fixed buys predictability (often at a small premium); variable is usually cheaper in flat markets but exposes you to spikes. Neither wins universally — the answer depends on the plans available at your address, their complete terms, and your own usage history.[1][2]

In deregulated states you shop competing offers on your state’s official portal (linked below); everywhere else, your utility’s own rate designs — tiered, time-of-use, or flat — are the menu, and the question becomes which of them fits your usage.

Quick Answer

A time-of-use plan changes the electricity price at defined times, but the periods, seasons, eligibility, and total bill effect are set by the specific utility tariff. DOE distinguishes time-of-use rates, which change by set amounts at set times, from dynamic rates tied to wholesale-market movement.[1]
