THEIR FIRST LIFE
WAS ON THE ROAD.
THE NEXT ONE POWERS CARE.
The distinctive innovation at Tamalpais Pediatrics is a 200 kWh storage system made from previously used electric-vehicle batteries. RePurpose Energy evaluates and repurposes suitable batteries for stationary energy storage, extending their useful life beyond transportation.
Paired with the clinic's 60 kW solar carport, these second-life batteries demonstrate a practical approach to circular energy. Grid Titans delivered the specialized electrical construction and integration needed to connect the system into the facility's energy infrastructure.

02 / THE CHALLENGE
CARE CAN'T
WAIT FOR
THE GRID.
Reliable electricity helps protect medical refrigeration, communication systems and the continuity of daily healthcare operations.
For Tamalpais Pediatrics, the solution integrates a 60 kW solar carport with 200 kWh of second-life electric-vehicle battery storage. Developed with RePurpose Energy through a California Energy Commission-supported demonstration, the project shows how EV batteries can have a productive second life beyond transportation.
Grid Titans was engaged to finish the remaining electrical construction, control integration and interconnection work required to bring the project into service.

A SECOND LIFE.
A STRONGER FUTURE.
A completed microgrid serving a real pediatric healthcare facility.
A completed healthcare microgrid pairing 60 kW of solar generation with 200 kWh of storage made from previously used EV batteries.
Grid Titans announced completion in July 2026. By integrating second-life electric-vehicle batteries with on-site solar, electrical distribution, and microgrid controls, the project demonstrates an alternative to sending useful EV battery modules straight to recycling. Grid Titans helped turn an innovative storage concept into installed energy infrastructure for a real pediatric clinic.
