How Prologis Warehouse Rooftops Are Powering Community Solar in California

June 22, 2026

Summary

Prologis is expanding community solar projects across the U.S., helping income-eligible households access renewable energy and lower electricity costs without installing rooftop solar at home.
In partnership with Clean Power Alliance and Ava Community Energy, Prologis has been developing rooftop solar portfolios in Southern and Northern California, totaling more than 16 megawatts of solar capacity.
By turning warehouse rooftops into local power sources, Prologis is helping bring more energy to communities and the grid.

A warehouse roof may not look like energy infrastructure, but Prologis has been using its rooftops to generate power close to where it’s needed.

In Oakland, California, Prologis and Ava Community Energy partnered on a new rooftop solar array — the first completed project in a five-site portfolio. In Southern California, a warehouse rooftop in Carson is helping power Clean Power Alliance’s community solar program. Across Prologis’ global portfolio, properties are located near major population centers, consumption hubs and areas where energy demand is high — creating opportunities for energy solutions where market conditions, customer needs and policy frameworks align.

Why Community Solar Programs Matter

Community solar is one way Prologis uses warehouse rooftops to support local energy needs. The company installs solar panels on select rooftops, supplying the power through local energy providers to eligible residents.

The model can be especially helpful for renters and residents in multifamily buildings who may not be able to install solar where they live. For participating households, community solar can lower monthly energy bills. For the grid, it adds generation closer to where electricity is used, helping support a more resilient energy system as demand grows.

Clean Power Alliance Partnership in Southern California

In Carson, Prologis and Clean Power Alliance recently completed and switched on a rooftop community solar project at Prologis’ South Bay 20 facility. The project will provide 100% renewable energy at reduced rates to approximately 500 local households. Discounted energy will also be provided to the City of Carson, helping reduce energy costs at City Hall. The project is part of Clean Power Alliance’s Power Share program, which is tied to California’s Disadvantaged Communities Green Tariff initiative.

Through the broader program, Prologis has executed power purchase agreements with Clean Power Alliance to install rooftop solar across 10 warehouse properties in Southern California. Together, these projects represent more than 9 megawatts of solar capacity and will serve about 4,670 homes. Those residents, spanning 38 communities, will see an estimated 20% savings on electricity bills.

This project is a powerful example of how collaboration between public agencies, private industry and community stakeholders can deliver meaningful results. This program makes clean energy savings accessible to renters and working families who have too often been excluded from the benefits of the clean energy economy.

Ava Community Energy Partnership in Northern California

In Northern California, Prologis’ partnership with Ava Community Energy includes projects in Oakland, Hayward, San Leandro and Tracy, totaling approximately 7.28 megawatts of solar capacity. The first completed project will help eligible East Bay households access 100% renewable power and electricity bill savings.

At Ava, our work is about making clean energy local, affordable and accessible. This project shows how we can bring new renewable generation online in the communities we serve while delivering real savings to eligible customers. Our partnership with Prologis is a practical example of how local energy programs, public policy and private-sector partners can work together to benefit residents.

Expanding community solar through partnership

Scaling distributed energy takes the right mix of policy, partners and real estate. State programs create the opportunity. Players like Ava Community Energy and Clean Power Alliance lead the community solar programs. Prologis brings the real estate platform, capital discipline and energy development capabilities to help turn that opportunity into operating projects.

Community solar is one example of how logistics real estate can do more than support the movement of goods. With the right partners and policy frameworks, existing rooftops can become local energy infrastructure, generating power close to where it is needed and providing more households access to renewable energy.
