How much does LUMA pay for my Enphase battery?

Q: How much does it pay exactly?

The incentive is around $1.00 per kWh your battery delivers during a program event. According to Enphase, a system of about 15 kWh of usable capacity can be eligible to earn more than $1,000 a year in incentives. The actual figure depends on the size of your system and how often the program is triggered.

Q: When and how often is it triggered?

Events generally happen during peak-demand evenings, between 7:00 and 11:00 p.m., most frequently from April to November. Enphase indicates they can occur between 75 and 100 times a year, lasting on average about two hours (four at most). Events depend on the grid's needs and are not a fixed number, so our simulator uses a more conservative estimate (~35 events a year) to avoid inflating the figures.

Q: Will I be left without backup power?

No. You can adjust your battery's discharge limit to reserve energy. Enphase suggests, for example, setting it around 20% to balance your earnings with a backup reserve for your home. Events happen during expected peak hours, not during an outage.

If you have an Enphase IQ battery in Puerto Rico, you can get paid for sharing part of your energy with the grid through LUMA's Customer Battery Energy Sharing (CBES) program. Here we explain how much it pays, who qualifies, and how to enroll.

The essentials: Through the CBES program, an Enphase battery can earn around $1.00 per kWh shared. Enphase estimates that a system of about 15 kWh (three IQ Battery 5P units) can earn more than $1,000 a year.

How much does it pay exactly?

The incentive is around $1.00 per kWh your battery delivers during a program event. According to Enphase, a system of approximately 15 kWh of usable capacity can be eligible to earn more than $1,000 a year in incentives. The actual figure depends on the size of your system and how often the program is triggered.

An honest note: the rate and conditions are set by the program and can change over time. Treat the $1.00 per kWh and the $1,000-a-year estimate as figures published by Enphase, not as a fixed promise. Always confirm the current terms before you count on that income.

Who qualifies?

Requirement	Detail
Net metering	Be a residential or small commercial customer enrolled in LUMA's Net Metering program.
Enphase battery with solar	Have an Enphase IQ battery installed and interconnected, connected to a solar photovoltaic system.
Interconnection agreement	Have an interconnection agreement that covers both the solar system and the battery.

How do I enroll?

Once your system has Permission to Operate, enrollment is done through the Enphase Enrollment Portal, where you provide your name, email, address, phone, LUMA account number, and premise ID. Applications are usually accepted or rejected within two to three weeks.

If you prefer not to navigate the process alone, a certified installer can confirm your eligibility and handle the enrollment for you, at no cost.

Will I be left without backup power?

No. You can adjust your battery's discharge limit to reserve energy. Enphase suggests, for example, setting it around 20% to balance your earnings with a backup reserve for your home. Events happen during expected peak hours, not during an outage.
