The payment is around $1.00 for every kWh your Powerwall shares during an event. The exact amount is set by the aggregator (Tesla) and can change over time. Events happen during peak demand, usually between 7:00 and 11:00 p.m., mainly from April to November, and last a few hours.

How to Activate CBES in Puerto Rico With Your Tesla Powerwall

Q: What is the CBES program?

CBES stands for Customer Battery Energy Sharing. It is a virtual power plant: instead of firing up a costly plant during peak demand, LUMA links thousands of residential batteries and draws a little energy from each one right when the grid needs it most. As the battery owner, you get paid for that stored energy.

Q: Does my Tesla Powerwall qualify?

In general you need a Powerwall connected to solar, enrollment in LUMA's Net Metering program, enrollment through Tesla (an approved LUMA aggregator), and only one aggregator at a time.

Q: How do I enroll with Tesla?

Confirm eligibility (Powerwall connected to solar and net metering with LUMA), enroll through Tesla as your aggregator (usually via the Tesla app or with help from your installer), set your reserve level, and start earning payments for the events your battery participates in.

Q: Will I lose my backup during an outage?

No. Only part of your energy is shared, and you set a minimum reserve level for your home. Events also happen during predictable peak hours, not during an outage or emergency.

If you have a Tesla Powerwall installed in Puerto Rico, there's a good chance you could be earning money with it — and many owners don't even know it. Through LUMA's Customer Battery Energy Sharing (CBES) program, your Powerwall can share a little energy during peak hours and get paid for it.

The essentials: Tesla is one of the approved aggregators for LUMA's CBES program. If your Powerwall is connected to a solar system and you're on net metering, you can enroll — at no cost — and earn around $1.00 per kWh shared.

What is the CBES program?

CBES stands for Customer Battery Energy Sharing. It's a virtual power plant: instead of firing up a costly plant during moments of peak demand, LUMA links thousands of residential batteries and asks each for a little energy at a time, right when the grid needs it most. You, the battery owner, get paid for that energy you already have stored.

Does my Tesla Powerwall qualify?

Generally speaking, to participate you need:

Requirement	Detail
Powerwall connected to solar	Your Powerwall must be connected to a photovoltaic system (solar panels).
Net metering	Be enrolled in LUMA's Net Metering program.
Through Tesla	Tesla is one of LUMA's approved aggregators; your Powerwall enrolls through Tesla's program.
A single enrollment	You can't be enrolled with two aggregators at the same time.

How much can I earn?

The payment runs around $1.00 for every kWh your Powerwall shares during an event. The exact amount is set by the aggregator — in this case Tesla — and can change over time, so it's worth confirming the current rate. Events happen during peak-demand hours, generally between 7:00 and 11:00 p.m., mainly from April to November, and last a few hours.

Let's be clear: your yearly total depends on the size of your system and how often the program is activated. It's extra income for energy you already have stored — not a fixed, guaranteed figure. Always verify the current terms with Tesla or a certified installer.

How do I enroll with Tesla?

The process, in simple steps:

Step	What happens
1. Confirm eligibility	That your Powerwall is connected to solar and that you're on net metering with LUMA.
2. Enroll with Tesla	Enrollment is done through Tesla as your aggregator — usually from the Tesla app or with help from your installer.
3. Set your reserve	You decide how much energy you allow to be shared and how much you keep as backup for your home.
4. Start earning	You accumulate payments for the events your battery takes part in.

If you're not sure whether you're already enrolled, or whether you're getting the right rate, a certified installer can review your account and activate you — at no cost and with no obligation.

Will I lose my backup during an outage?

No. Only part of your energy is shared, and you set a minimum reserve level for your home. Plus, events happen during expected peak hours — not during an outage or an emergency.
