Fixed vs Variable Electricity Rates for Ohio Businesses
The short answer
A fixed-rate contract locks the generation price per kWh for the term, so you know your budget. A variable product changes month to month — either at the supplier's discretion or tied to an index such as PJM hourly prices. Most Ohio small businesses choose fixed prices for certainty; larger, flexible users sometimes save with index or blended products. In 2026 the biggest difference between products is often how capacity is handled, not the energy price.
Product types compared
| Product | How the price works | Budget certainty | Typical fit |
|---|---|---|---|
| Fixed, all-in | One ¢/kWh including energy and capacity for the term | High | Small and mid-size businesses, thin-margin operators |
| Fixed with capacity pass-through | Fixed energy price; capacity billed at cost from your capacity tag | Medium | Sites that can cut load during summer peaks |
| Supplier variable | Supplier sets price monthly | Low | Short-term bridge only; read terms carefully |
| Index (hourly/day-ahead) + adder | PJM market price plus a fixed adder | Low | Large, flexible loads with controls and a risk policy |
| Block and index | A fixed block covers baseload; remaining usage floats on index | Medium | Mercantile accounts with steady baseload |
| Layered (hedged in tranches) | Buy portions of future usage at several points in time | Medium–high | Larger portfolios wanting to average entry prices |
What capacity prices mean for your choice
PJM capacity prices are now known for three years ahead: $329.17/MW-day for June 2026–May 2027, $333.44 for 2027/28 and $325.00 for 2028/29. Because they're known, a fixed price that includes capacity isn't a bet on capacity — it simply bundles a cost that's already set. A pass-through structure makes sense when you can reduce your capacity tag by cutting load during PJM's summer peak hours: at 2026/27 prices each kW of tag is worth roughly $120 a year.
Fixed-rate fine print that matters
- Bandwidth. How much your usage can change before volume true-ups apply.
- Pass-through clauses. Which costs can be added later (transmission, "change in law," new PJM charges).
- Renewal. Under HB 15 (2025), suppliers must notify you twice before a fixed contract rolls to a variable rate; many contracts still auto-renew on variable terms if you do nothing.
- Early termination. Usually a formula based on remaining volume and market prices.
See red-flag contract clauses.
When variable or index can make sense
- You have a written risk policy and someone watching the market.
- Your load is flexible (pre-cooling, storage, shiftable production).
- You're bridging a few months to a planned move, sale or aggregation start.
Index prices spike during heat waves and cold snaps; an unhedged index product can erase a year's savings in a week.
FAQ
Is a fixed or variable electricity rate better for a small business in Ohio?
Most small businesses are better served by a fixed price that includes capacity, because it matches monthly budgeting and 2026–2029 capacity costs are already known.
What happens when my fixed contract ends?
Unless you sign a new contract, many agreements roll to a month-to-month variable price. HB 15 requires two advance notices; calendar your end date anyway.
Can I switch from variable to fixed at any time?
Usually yes for supplier variable products, subject to the contract's notice terms and the next meter-read date.
What is a block-and-index product?
You fix the price for a block of steady baseload and buy the rest at market index prices — common for larger accounts with predictable baseload.
