A bill for an act relating to solar energy by establishing a community solar facility program.

HSB 629 establishes Iowa's community solar facility program, allowing residents and businesses to subscribe to shared solar projects and receive bill credits for the electricity generated. The bill defines key terms like "community solar facility" (capped at 5 megawatts, or 20 MW on brownfield sites) and requires facilities to have at least three subscribers, with 60% of capacity subscribed by customers using 40 kW or less. It clarifies that community solar does not count as a public utility or unnecessary duplication of infrastructure, and mandates utilities to provide bill credits that roll over monthly if they exceed a subscriber's bill. The program also sets a statewide 250-megawatt capacity limit until a new solar valuation method is adopted.
