• In early 2026, Sunrun reported that in 2025 it rapidly scaled its distributed power plant programs, enrolling more than 106,000 customers and dispatching nearly 18 gigawatt-hours of home battery energy across 17 programs to support stressed U.S. grids.
• This expansion signals Sunrun’s growing role as a source of flexible, dispatchable capacity comparable to fossil-fuel peaker plants, highlighting how residential solar-plus-storage is becoming integrated into mainstream grid reliability planning.
• We’ll now examine how Sunrun’s rapid growth in distributed power plant participation shapes the company’s investment narrative and future positioning.

What Is Sunrun's Investment Narrative?

For Sunrun, the core belief you’d need as a shareholder is that residential solar-plus-storage can evolve into a meaningful, grid-level capacity resource, not just a rooftop product. The 2025 distributed power plant results fit directly into that thesis: a fivefold jump to 106,000 participating customers and 18 gigawatt-hours dispatched shows Sunrun can aggregate and operate a large virtual fleet when grids are under strain. In the near term, that strengthens key catalysts already on the table, such as recurring grid services revenue, the new HASI joint venture, and utility partnerships in Texas and California. It may also slightly rebalance the risk profile. Sunrun’s limited cash runway and reliance on securitizations still matter, but execution risk around scaling and delivering reliable dispatch now sits more squarely alongside financing and policy risk.

However, this grid-services push also raises new questions around capital intensity and program profitability that investors should watch closely. The valuation report we've compiled suggests that Sunrun's current price could be quite moderate.
