IA HSB81

Establishes a community solar facility program to encourage solar energy generation and allow electric utility customers to participate in and benefit from solar energy projects

Defines community solar facilities as distributed generation facilities up to 5 megawatts (or 1 megawatt with relaxed subscriber requirements) that generate electricity via solar photovoltaic devices and provide bill credits to subscribers

Requires electric utilities to provide bill credits to subscribers based on their proportional share of facility output, with excess credits carrying over indefinitely to future bills for at least 25 years from facility operation date

Sets facility requirements including minimum 3 subscribers, no single subscriber holding more than 40% interest, at least 60% capacity subscribed in portions of 40 kilowatts or less, and 1-mile spacing between facilities under common control

Requires the Iowa Utilities Commission to adopt implementation rules and mandates electric utilities file new or updated tariffs by January 1, 2026, while specifying that community solar facilities are not considered public utilities
