CBES program payout

How much LUMA pays to share your battery

$1.00 / kWh shared

During CBES (Customer Battery Energy Sharing) program events, LUMA pays for the energy your battery sends back to the grid above your backup reserve. You decide how much energy you keep for outages.

*Illustrative estimate assuming $1.00/kWh and a conservative estimate of ~35 events per season (Apr–Nov); some aggregators like Enphase report up to 75–100. Events depend on the grid's needs — they're not a fixed number. Actual payout varies based on your equipment, your usage, and how many times the program is activated. This is not a promise.

How your energy flows

Solar → Battery → your home, even in an outage

By day your solar array charges the battery. When LUMA goes down, your battery keeps powering the essentials. When the grid is up, you share the surplus with the CBES program.

Illustrative diagram of the energy flow. Backup availability and CBES program payouts depend on your equipment, your reserve, and grid conditions. This is not a promise of uninterrupted service.
