Rules by state

Solar and battery interconnection rules in North Dakota

North Dakota small power production and net energy billing. Every threshold below was read out of the document linked at the bottom of this page, and the same rules answer the free screening check.

Who this binds: investor owned utilities. A utility outside that list sets its own terms, so confirm who serves the address first.

How the size is measured: not published

The published limits here are stated in kilowatts without saying whether that is the inverter rating in alternating current or the array rating in direct current. On a system near a threshold that decides which band it lands in, so the checker asks the question rather than choosing an answer.

Size bands and what each one obliges

Net energy billing, up to 100 kW Size 0 to 100 kW

A qualifying facility with a design capacity of 100 kilowatts or less is entitled to net energy billing, where the output reverses the meter used to measure sales to the facility. The purchasing utility may recover metering costs associated with production monitoring from the facility.

  • No more than 100 kW design capacity
  • Interconnection costs paid by the facility, recoverable over a reasonable period

The screens that decide it

Ask the utility this, before you sell it

  1. Is this address served by a rural electric cooperative or a municipal utility? This chapter reaches neither, and in North Dakota that covers most of the state by area.
  2. Is the 100 kilowatt limit measured in alternating or direct current? The chapter says design capacity and never defines it.
  3. What interconnection costs will be charged, and over what period may they be repaid? The chapter obliges the facility to pay them and allows reimbursement over a reasonable period but sets no amounts.

Worth knowing before you quote

North Dakota publishes no review levels, no screens, no application fee, no study deposit, no insurance provision and no approval or permission to operate timeline, all confirmed by reading the chapter. What it does publish is a bare obligation: an electric utility shall make such interconnections with any qualifying facility as may be necessary, and shall offer to operate in parallel. Storage is not addressed; the chapter predates it by four decades. The only day count is that the obligation does not attach to a facility of 500 kilowatts or more until ninety days after it notifies the utility that it is a qualifying facility.

Source

North Dakota Administrative Code Chapter 69-09-07, small power production and cogeneration, effective 1 June 1981

Read and recorded 2026-09-12. The narrowest applicability of any state read. The chapter governs sales and purchases between qualifying facilities and electric utilities, and electric utility takes the statutory meaning of electric public utility, which is a privately owned supplier of electricity offering to supply the general public. The statute treats a rural electric cooperative as a separate category throughout, so cooperatives and municipals are outside this chapter. In a state where cooperatives serve most of the land area that is the dominant fact.
