Solar and battery interconnection rules in PR

The screens that decide it

• Interconnection deposit, by the codified fee formula

  The statute sets the interconnection deposit at $0.05 per watt of AC capacity, capped at whichever is less: $250 for a residential account, $1,000 for commercial, $2,000 for industrial. This figure is stated as AC capacity in the statute text, unlike the 25 kW threshold on LUMA’s own program, which is not qualified either way.

Ask the utility this, before you sell it

1. Is there a distinct net metering eligibility cap separate from the interconnection technical limit? The materials read did not distinguish the two.

Worth knowing before you quote

Net metering for a new customer today is full retail, the same as a legacy customer, and is not scheduled to move to a lower net billing credit: Act 10-2024 bars the Puerto Rico Energy Bureau from restudying the program before January 2030 at the earliest, with any resulting change taking effect no sooner than twelve months after the Bureau acts. That lock is itself being challenged in court by the island’s Financial Oversight and Management Board, so treat the current program as durable rather than permanently settled. The consolidated interconnection regulation covers any generating facility or microgrid seeking to interconnect, excluding only islanded systems, and replaced two prior PREPA regulations that used to be split by distribution versus transmission level. Puerto Rico has no counties; permit offices in this platform are seeded one per municipio, the Census Bureau’s county equivalent for the territory, and which municipios hold independent permitting authority versus route through the central permitting office, OGPe, has not been confirmed. Ask the specific municipio which applies before assuming either way.
