Connecticut Business Energy Bill Audit Guide

For a Connecticut business, identify whether the current electric account receives a third-party supply product or an applicable utility default service. Eversource and United Illuminating accounts can have different supply categories and pricing periods. A small-business Standard Service comparison should not be transferred automatically to a larger-load account.

Use the correct default-service context

PURA's October 7, 2026 procurement update concerns Standard Service for residential and small-business customers. Its supplier handbook also references the statutory framework for Standard Service and supplier-of-last-resort service. These references explain why the business's actual account classification matters more than a general statewide headline price.

Read the tariff/service designation and effective period on the utility's current information. If the business already buys competitive supply, the relevant starting point is its current agreement rather than an unrelated default-service number. Ask what the proposed offer replaces and which cost components it includes.

Match the period as well as the price

A supplier proposal may fix a price for a different period than the current baseline. Record the start and end dates of both, along with any renewal or notice provision. Today's utility default price cannot establish a fixed twelve-month baseline if it is scheduled to change during the modeled year.

For a business with electric heating, summer cooling or production cycles, use twelve monthly kWh values. Note changes in operating hours and equipment. A comparison based only on a low-use spring invoice can understate the significance of a rate difference and misrepresent the coming year's budget.

Keep gas review separate

An electric supplier's eligibility does not establish that the same business has a comparable retail gas option. Identify the gas utility, tariff and supplier arrangement independently. Where a gas supply quotation is available, record its price unit, transportation treatment and any separate fees before using the gas calculator.

Avoid combining the two fuels into one average energy price. A company managing an office's electricity and a kitchen's gas should retain separate account histories and proposed agreements, even when the same adviser reviews them together.

A Connecticut office comparison example

Consider a hypothetical office with 96,000 annual kWh. Equivalent entered supply prices of 12.0¢ and 11.3¢ create a $672 annual difference before separate fees. An additional $12 monthly supplier fee would reduce that modeled difference by $144, leaving $528. The values illustrate why the headline rate alone is incomplete; they are not current Eversource, UI or supplier rates.

If the current price applies for only part of the year, do not label this result a forecast. A reviewer needs the actual schedule and comparable effective periods to assess that issue. The constant-price tool can still show a clearly labeled scenario, with its limitations attached.

Questions to take into the review

Identify the account's default or competitive supply category, the components included in each rate and the treatment of recurring fees. Ask whether a price is conditional on usage or a particular start date. Keep written confirmation with the comparison so a later reader can reproduce the assumptions rather than relying on a screenshot of a quoted rate.

Use the result as a starting point

Once the current and offered components match, use the business bill checker to show the arithmetic. It holds entered prices constant, does not fetch live offers, and does not independently calculate utility demand, delivery or tariff charges. Use the optional twelve-month usage series when one month is unrepresentative.

For an account question, send your business, state, utility and the issue through the first-party review form. Keep bills and account identifiers out of the initial message; arrange document sharing after connecting. A listing in this guide is not a supplier-availability guarantee.
