Fixed vs. Variable Utility Pricing

Jeff Clark

April 6, 2026

Choosing between an index (variable) and a fixed price energy contract can be confusing but it is a fundamental strategic decision. The decision resides in your appetite for risk versus your need for budget certainly. Below is an overview of how these two structures compare.

The Stability of Fixed Price Contracts

A fixed price contract offers the ultimate “peace of mind” by locking in a specific rate for a
specific term. This type of contract protects you from the inherent volatility of the energy
market, where prices can spike due to extreme weather, geopolitical tensions, or supply
disruptions.

For organizations with strict budget compliance needs, this type of contract makes long-term
budgeting simple and eliminates the risk of “bill shock” during high-demand seasons.

The Risk and Reward of Index Contracts

In contrast, an index contract or market-based contract aligns your price to the prevailing
market rate. The primary advantage of this type of contract has the potential for significant
savings; if market prices drop, your rate drops also.

However, this flexibility comes with substantial risk. If the market becomes bullish, your
energy costs can increase, leaving you exposed to price peaks that a fixed contract would
have shielded you from. When you buy directly from your service area utility company, this
is what you are getting.

Finding the Right Fit

Ultimately, the decision hinges on your financial flexibility and appetite for risk. Fixed price
contracts are generally preferred by those who value stability over potential savings,
acting as a form of insurance against market spikes. Index contracts are better suited for
those with the liquidity to absorb price swings in exchange for the chance to pay lower
“wholesale” prices. Some consumers even opt for a “hybrid” approach, fixing a portion of
their load while leaving the rest on the index to balance security with opportunity.

So, the choice is truly yours to decide and the experts here at AMRA are well positioned to
assist you in making an informed decision.
