Solar and battery interconnection rules in Arkansas

Arkansas net metering and interconnection. 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, electric cooperatives. A utility outside that list sets its own terms, so confirm who serves the address first.

How the size is measured

kilowatts alternating current. The statute states both limits in alternating current, and the standard interconnection agreement collects the generator rating in DC and the inverter rating in AC separately, with the statutory test running on the AC figure.

Size bands and what each one obliges

Residential, up to 25 kW AC Size 0 to 25 kW

The limit is the lesser of 25 kW alternating current or 100 percent of the highest monthly usage in the previous twelve months, and the rule says plainly that whichever is lower applies. Arkansas publishes no insurance requirement and no aggregate program cap.

  • Lesser of 25 kW AC or 100 percent of highest monthly usage
  • Standard interconnection agreement filed at least 30 days ahead
  • One time review fee set in the utility tariff
Non residential, up to 5,000 kW AC Size 25.001 to 5000 kW

The limit is the lesser of 5,000 kW alternating current or 100 percent of highest monthly usage. A facilities study deposit may be charged at the amount in the utility tariff.

  • Lesser of 5,000 kW AC or 100 percent of highest monthly usage
  • Facilities study deposit per the utility tariff

The screens that decide it

Ask the utility this, before you sell it

  1. What was this customer highest monthly usage in the previous twelve months? Arkansas converts that to a facility size limit as the output that would meet usage in that same month of the year, and the lower of that and the statutory kilowatt cap controls. It is a monthly test, not an annual one, which is unusual.
  2. What is the one time interconnection review fee and the facilities study deposit in your tariff? Arkansas authorizes both but publishes no amounts.
  3. Is this address served by a municipal utility? If so this rule does not apply and the municipal governing body sets the terms.

Worth knowing before you quote

Arkansas publishes no insurance requirement and no prohibition, confirmed by searching the rule and the standard interconnection agreement. There is no aggregate program cap and no capacity tiers, and no 15 percent or minimum load screen: a facilities study is used instead of published screens. Timelines are in calendar days: 30 to review plans and respond, 30 for a preliminary site review with multiple reviews not exceeding 90 days, and reasonable efforts to complete a facilities study within 120 days. No permission to operate clock is published.

Read and recorded 2026-09-12. Applies to every electric utility jurisdictional to the Commission, and the statutory definition of electric utility expressly includes an electric cooperative, so cooperatives are covered. Municipal utilities are not: a municipal allows interconnection under ordinances set by its own governing body, and may only cut the size limit below the state figures after finding that is necessary for reliability or public safety.
