In a heartwarming development for clean energy advocates and homeowners alike, two industry leaders are teaming up to bring sustainable power to tens of thousands of American families. HASI (HA Sustainable Infrastructure Capital) and Sunrun have announced the successful launch of an innovative joint venture that promises to transform how homes across the country access and use energy.

The partnership, which officially closed in December 2025, will see HASI investing up to $500 million over the next 18 months to support the installation of home solar panels and battery storage systems. The result? More than 40,000 households will gain access to cleaner, more reliable energy while contributing over 300 megawatts of renewable capacity to the nation's power grid.

What makes this collaboration particularly exciting is how it builds on a strong foundation of trust and success. HASI and Sunrun first began working together back in 2018, and this new venture represents the natural evolution of that relationship. Marc Pangburn, HASI's Chief Revenue and Strategy Officer, emphasized the mutual benefits, noting that together they're "accelerating the development of essential infrastructure through home-based energy systems that improve grid reliability and address growing power demand."

For homeowners, this partnership means greater access to solar and battery storage solutions that can provide energy independence, cost savings, and peace of mind during power outages. Sunrun, already America's largest provider of home battery storage and solar systems, pioneered the no-upfront-cost subscription model that has made clean energy accessible to families who might not have thousands of dollars available for installation costs.

Danny Abajian, Sunrun's Chief Financial Officer, celebrated the innovative nature of the financing structure, calling it "a first-of-kind for residential storage and solar financing." This creative approach to funding means that more resources can flow directly into expanding clean energy access rather than being tied up in traditional financing constraints.

Beyond individual homes, this venture represents a significant step toward a more resilient and sustainable energy future for entire communities. Home-based energy systems don't just benefit the families who install them—they also support the broader electrical grid by providing on-demand, dispatchable power that enhances reliability for everyone.

HASI brings impressive credentials to the partnership, with more than $15 billion in managed assets across various sustainable infrastructure projects, including utility-scale solar, wind, and energy efficiency initiatives. Their deep expertise in energy markets combined with Sunrun's proven track record in residential energy systems creates a powerhouse team positioned to make real, lasting impact.

As our nation works toward a cleaner energy future, partnerships like this one demonstrate that progress is not just possible—it's happening right now, one rooftop at a time. For the 40,000+ families who will benefit from this initiative, it means taking control of their energy future while contributing to a healthier planet for generations to come.
