Solar and battery interconnection rules in Florida

Florida PSC net metering tiers (investor owned utilities). 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

gross power rating: the AC nameplate generating capacity of the renewable generation system, which for inverter based systems the rule computes as the installed DC nameplate capacity multiplied by 0.85. The inverter rating does not determine the tier, and storage is not renewable generation so it is not counted here.

Size bands and what each one obliges

Tier 1 Size 0 to 10 kW

The simplest path. At a gross power rating of 10 kW or less the utility cannot require further design review, testing, or additional equipment beyond what the rule already specifies. Remember the rating is computed from the array DC nameplate times 0.85, not from the inverter.

  • Standard interconnection agreement
  • Proof of general liability insurance as specified in the rule
Tier 2 Size 10.001 to 100 kW

Above 10 kW and up to 100 kW. Still a standard path with no additional design review required beyond the rule, but the insurance and agreement terms step up.

  • Standard interconnection agreement
  • Higher general liability insurance limit than Tier 1
Tier 3 Size 100.001 to 2000 kW

Above 100 kW and up to 2 MW. The utility may determine that an interconnection study is necessary. Where it does, it must execute the standard agreement within 90 days of a completed application.

  • Standard interconnection agreement
  • Possible interconnection study
  • Highest insurance limit of the three tiers

The screens that decide it

Ask the utility this, before you sell it

  1. Confirm the gross power rating you will assign this system, since the tier follows from it.
  2. Which interconnection tier and application form applies to this system size?
  3. What general liability insurance limit and additional insured wording do you require at this tier?
  4. Is there an application fee or study deposit, and what is the current queue time?

Worth knowing before you quote

Applies to investor owned utilities under PSC jurisdiction. Municipals and cooperatives set their own terms and are deliberately excluded from this set.

Florida Administrative Code Rule 25-6.065, Interconnection and Metering of Customer-Owned Renewable Generation

Read and recorded 2026-09-12. Binds investor owned utilities under Public Service Commission jurisdiction. Municipal utilities and rural electric cooperatives are not bound by this rule.

What to do with this

Check a real address

The rules below are the general case. Run the free check to see which utility serves a specific address, which tier the system lands in, and what to ask.
