Eversource Connecticut vs. United Illuminating for Businesses

Find the correct default supply category

PURA’s materials distinguish utility supply arrangements and third-party supplier participation. Its historical reporting describes Standard Service for smaller loads and Last Resort Service for larger commercial loads, but an actual decision requires current utility rules and the account’s classification. Do not apply a residential Standard Service rate to a larger business merely because both are served by the same utility.

Gather the bill’s utility, rate schedule, usage and demand determinants. For a leased property, establish whether the business or landlord is the customer of record. A comparison of tenant-only use at one property with whole-building service at another would misstate the result before any supplier or tariff difference is considered.

Compare business supply contracts on matched scope

Request actual offers for the relevant utility and class, with the same delivery period, energy assumptions and included components. Ask how capacity, transmission, losses or other supplier items are handled. If the applicable utility supply price resets during the proposed term, separate known values from planning assumptions.

Keep the delivery utility role distinct. A competitive supplier arrangement does not move the premises into the other distribution territory or eliminate the local network tariff. Demand and fixed charges may influence the effective bill even when the supplier energy rate is unchanged.

Hypothetical default-reset example

Assume 120,000 kWh evenly split across two six-month periods. A hypothetical default supply price of $0.11 for the first half and an assumed $0.09 for the second gives $6,600 plus $5,400, or $12,000. An invented annual fixed supplier price of $0.102 gives $12,240 before fees.

If the second default period instead equals $0.12, the modeled default total becomes $13,800. The future value is a scenario, not a current tariff or forecast. This example shows why extending one published six-month figure across a full year can produce a false comparison. Real seasonal use would also require different weighting.

Verify classification and preserve the quote file

Use current PURA and utility resources to confirm the business’s supply category and supplier eligibility. Retain the actual offer, entity, contract version, component schedule and renewal dates. Ask for clarification when a sales presentation relies on a residential comparison that does not match the bill.

Review enrollment timing and the first subsequent invoices after any authorized change. A sound decision may retain utility supply or choose a supplier depending on the actual costs and obligations. This guide gives no Eversource-versus-UI winner or current supply price; it helps the business align customer class, time period and tariff scope before comparing.
