Rate Schedules & Tariff Analysis
SCG's bill splits into a regulated distribution (delivery) component set in the PURA tariff and a gas-supply (commodity) component that C&I customers can shop competitively. Published summary pages list rate codes and effective dates but not per-Ccf dollar figures, which live in the individual tariff sheets. EIA's Connecticut delivered-price series is a useful verified benchmark for total cost trends.
The Southern Connecticut Gas Company Rate Schedule List
| Schedule | Applicability |
|---|---|
| SGS — Small General Service | Smaller commercial; customer charge + per-Ccf distribution (tariff). |
| MGS — Medium General Service | Mid-size commercial; customer charge + per-Ccf distribution (tariff). |
| LGS — Large General Service | > 30,000 Ccf/yr with daily demand metering; customer/demand + per-Ccf distribution. |
| IS — Manual Interruptible Service | Curtailable/dual-fuel loads; interruptible distribution pricing. |
| TRS — Transportation Receipt Service | Third-party supply delivery; transportation + balancing. |

The Southern Connecticut Gas Company Data Access FAQ
How does a C&I customer get interval gas data from SCG?▾
Use the Energy Analyzer inside My Account. It provides hourly consumption with weather overlay and exports to PDF, CSV or XML, with 12-13 months of history. There is no Green Button export; for very large accounts, daily demand-metering data is available and custom requests can be made via Customer Care.
Can an energy consultant access an SCG account on the customer's behalf?▾
Yes. Under Connecticut's Gas Code of Conduct (16-47a-3) the customer signs a Customer Information Disclosure Authorization and adds the consultant as an authorized user in My Account. The consultant then logs in with their own credentials to view bills and export Energy Analyzer data.
Can a commercial customer choose its gas supplier?▾
Yes. Connecticut gas supply is competitive, so a C&I customer can buy the gas commodity from a registered marketer while SCG continues to provide regulated distribution. The distribution (delivery) charges in SCG's PURA-approved tariff still apply regardless of supplier.
Which rate class applies to a large commercial or industrial site?▾
SCG assigns class by usage/demand: Small General Service (SGS), Medium General Service (MGS) and Large General Service (LGS, generally >30,000 Ccf/yr with daily demand metering), plus Interruptible Service (IS). Exact distribution charges per Ccf and the monthly customer charge are set in the PURA-approved tariff (see the LGS/MGS rate sheets).
Does SCG publish an API for usage data?▾
No. There is no public developer API or Green Button Connect My Data. Programmatic-style access is limited to Energy Analyzer CSV/XML exports, the Marketer Services portal for enrolled suppliers, or custom data feeds requested through Customer Care or Transportation Services.
