What This Means for Your Business
- It changes on United Illuminating's schedule, not yours. A fixed price from a licensed supplier locks the number for the term you choose.
- What it's worth: Every 1¢ per kWh a supplier can beat the default price by is worth about $50 a month, or $600 a year, for a business using 5,000 kWh a month.
- It's a benchmark, not a quote. Licensed suppliers price your actual account. Whether an offer beats it depends on your usage, start date, and term.
- Capacity matters for bigger accounts. United Illuminating is in ISO New England, where capacity costs are part of what you pay. Check how any contract handles them.
- January to June 2026 the price was 13.695¢. Connecticut's standard service price changes every January 1 and July 1.
- Business, time-of-use, and electric heat rates differ; check your latest bill.
