Connecticut: Build a month-by-month exposure map
Start with EIA: supply, demand, weather and storage price drivers. The table below links this decision to the represented gas companies in Connecticut. It does not establish service or supplier availability for every account.
Use weighted prices
For each month, multiply projected therms by that month’s assumed supply price. Add applicable fixed fees separately. An unweighted average gives a low-volume summer month the same influence as a high-volume heating month.
Separate price exposure from operating exposure
A fixed commodity component does not establish firm transportation or remove a curtailment obligation. Ask operations to review notice and response requirements independently of finance’s price scenario.
Connecticut utility application
| Gas service company | Seasonal cost and service exposure | Primary reference |
|---|---|---|
| Southern Connecticut Gas | PURA approval, utility-active marketer and accepted start date | Official program / tariff |
| Yankee Gas / Eversource | PURA approval, utility-active marketer and accepted start date | Official program / tariff |
| Connecticut Natural Gas | PURA approval, utility-active marketer and accepted start date | Official program / tariff |
| Norwich Public Utilities | NPU commercial terms and any available supplier arrangement | Official program / tariff |
Southern Connecticut Gas: the program detail behind this decision
PURA describes firm transportation for commercial and industrial customers. The state’s approved gas-marketer information and the actual distribution company’s active enrollment requirements answer different questions. The town roster identifies the gas distributor separately from interstate transmission pipelines. Program Connecticut.
Apply the evidence to an account file
In the monthly budget, keep Marketer supply, utility transportation and any metering or data charges visible. Obtain the service response for PURA approval, utility-active marketer and accepted start date before assuming that a winter price arrangement also guarantees the required operating flexibility.
Worked check: an average can hide the heating load
Assume a hypothetical two-month illustration uses 3,000 therms at $1.00 and 1,000 therms at $0.60. The commodity total is $3,600 and the usage-weighted price is $0.90 per therm. The simple average price is $0.80; applying it to 4,000 therms understates the illustration by $400. No fees or delivery charges are included. This is arithmetic, not a claim about which local months or prices will be higher. Use all twelve actual delivery months for the real budget.
Turn the review into a calculation
Build a monthly weighted budget. Enter documented assumptions in matching energy units. Keep any charge outside both supply offers separate; the result does not establish eligibility or an available quote.
Read the Connecticut utility guide for the wider service-company distinctions. Convert billed gas units using the bill’s heat-content factor when moving from volume to energy.
