Commercial Electricity Rate Report: Q3 2026

Capacity costs, storm-driven spikes, and global market swings have pushed commercial electricity rates well past what a standard annual escalator accounts for. This Commercial Electricity Rate Report takes a tariff-level look at what drove electricity costs through the first half of 2026. It turns that analysis into key takeaways for building a 2027 budget, starting with separating what's predictable and controllable from what needs to be hedged.

Arcadia’s Rate Report covers:

• What drove commercial rates up in H1 2026. A look at the specific drivers behind the increase, from structural costs to weather events.
• How much of your bill is predictable. Rates vary widely by location and tariff, but when you break a bill into its components, most of the cost is set by forward markets, published tariffs, and filed rate cases — leaving only a few pieces that are truly variable.
• Know which lever to pull, and when. Five key takeaways for building a 2027 budget, from retiring the flat-escalator model to knowing when to hedge and when to optimize your tariff.

Behind the Data

For this report, we modeled costs across 20 commercial building profiles — from small offices to large hospitals — at a geographically diverse sample of US utilities, with each result broken down by individual charge components. Every calculation runs directly through Arcadia's tariff engine, drawing on a database of 30,000+ North American tariffs, giving this update a detailed, comparable picture of how electricity costs actually shift across building types, utilities, and rate structures.
