A commission’s consumer division is not a courtesy line. In most states a company must hold a disconnection while a formal complaint about that account is open, which is a different and stronger thing than asking the company to reconsider. Ring the utility first, then the commission if the answer is no.

This is where an electric disconnection physically happens, and it is also why the rules are written by a public utility commission rather than a legislature in a good many states: the commission regulates the company that owns this wire. “Residence service drop”, Chetvorno, CC0

Who it covers

Does the South Dakota rule cover your utility

The rule binds the utilities South Dakota Public Utilities Commission regulates. A household on a municipal system or a rural cooperative is covered by that system's own policy instead.

That means a rural electric cooperative and a municipal light or gas department in South Dakota answer to their own board or their own city council on this, not to South Dakota Public Utilities Commission. Many adopt a winter policy of their own that is as protective or more so, and the place to find it is the cooperative's or the town's own tariff.

The rule names electric and natural gas service.

Help with the bill

South Dakota pays part of the heating bill through Low Income Energy Assistance Program (LIEAP)

A shutoff rule and a heating grant are separate things, and in several states an approved grant application is itself what satisfies the filing the shutoff rule asks for. South Dakota Department of Social Services, Office of Energy Assistance runs it. The income test is The department publishes a three month gross income limit table for the 2025-2026 heating season rather than a stated percentage, and a household must be at or below the limit for its size..

A residential natural gas meter with its regulator and shutoff valve, mounted against pale house siding — A gas meter, which is the other half of the question and frequently the other half of the answer. A state rule can reach a regulated gas company and not reach the electric cooperative next door, or the reverse, so the protection you have often depends on which company sends which bill. “Gas meter”, RadRafe, Public domain
