Enphase Energy to Pair with Arizona Public Service on Pilot Grid Services Program

Microinverter-based solar and battery systems maker Enphase Energy, will work with Arizona Public Service on that utility’s residential battery pilot grid services program.

The program offers homeowners with Enphase IQ Batteries in APS’s service territory two ways to participate and earn money through one-time, upfront incentives.

Customers who sign up for the program and simply share their data with APS, including basic information about them and their Enphase Energy System, will earn $500 per installed kilowatt of battery capacity with a cap of $2,500 per home.

Alternatively, homeowners can enroll in the program, share their data with APS, and allow the utility to use the stored energy from their batteries on demand. These customers will be eligible to earn the same $500 per installed kilowatt of battery capacity (up to $2,500 per home), plus an additional one-time payment of up to $1,250, for a total maximum incentive of $3,750 per home. Program participants will be enrolled for a term of three years with both options.

APS expects to call upon enrolled batteries for additional power to meet demand up to 100 times per year. Participants must be APS residential customers and be on a time-of-use (TOU) service plan or a grandfathered service plan with a solar energy rate rider. The program is designed for newly interconnected batteries. Customers with existing batteries are not eligible to enroll.
