Bill
HSB 81
Creates a community solar program letting utility customers subscribe to solar facilities, earn bill credits, with IUB rules and updated tariffs by 2026.
Status and timeline
- Introduced: January 23, 2025
- Committee actions: Subcommittee recommendation for passage (Jan 27, 2025); Committee report recommending amendment and passage (Feb 11, 2025); Committee report approving bill and renumbering as HF 404 (Feb 13, 2025)
- Current status: Committee-approved bill, renumbered HF 404
- Jurisdiction: Commerce/Utilities (Iowa)
Purpose and intent
- Establish a community solar facility program to encourage solar energy generation and broaden participation for electric public utility customers.
- Allow customers who cannot or prefer not to install on-site solar to participate in and benefit from solar projects through a “subscription” model.
Key definitions
- Subscriber: a customer of an electric utility who owns at least one share of a subscription to a community solar facility.
- Subscriber organization: a for-profit or nonprofit entity that owns or operates one or more community solar facilities.
- Subscription: a proportional contractual interest in a community solar facility.
Core provisions and requirements
- Program establishment: Creates a framework to facilitate community solar projects and participation by utility customers.
- Billing: Electric utilities must bill subscribers using methods established under Code section 476.49.
- Interconnection review: Utilities must review interconnection processes with community solar facilities to ensure adequacy, efficiency, and cost-effectiveness; investor-owned utilities may recover reasonable interconnection costs.
- Metering and participation: A subscriber may include all of the subscriber’s electric meters in the community solar facility (broadening how a customer can participate).
- Ownership: A community solar facility may be owned by investors (i.e., investor-owned entities can own facilities).
- Administration of credits and data: The bill sets specific procedures and requirements for administering bill credits and managing subscriber information.
- Regulation and rulemaking: The Iowa Utilities Board (IUB) is tasked with adopting rules implementing the bill’s provisions.
- Tariffs: Electric utilities must file new or updated tariffs, if applicable, by January 1, 2026, to implement changes resulting from the bill.
Affected parties
- Electric utilities (including investor-owned utilities)
- Solar facility developers and owners (including investor-owned or nonprofit entities)
- Subscribers (utility customers who own a subscription)
- Subscriber organizations (owners/operators of community solar facilities)
- Iowa Utilities Board (rulemaking and oversight)
Procedural and timeline highlights
- Tariff filings: Required by January 1, 2026, to reflect the program’s changes.
- Rulemaking: IUB to adopt implementing rules.
- Ongoing governance: Program design, credits administration, and interconnection processes will be guided by future rules and tariffs.
Potential impacts
- Expanded access to solar energy for utility customers who cannot install on-site systems.
- Increased participation in solar through subscriptions, with credits tied to utility billing.
- Utility interconnection processes may be standardized and potentially streamlined; interconnection costs may be recoverable for investor-owned utilities.
- Investment activity in community solar facilities could rise due to investor ownership eligibility.
- Requires utilities to update tariffs and align billing practices with the new program.
Next steps for readers
- Monitor IUB rulemaking and tariff filings slated for 2026 to understand how credits, interconnection, and interutility charges will be implemented.
- Stakeholders may engage in the submittal of comments during rulemaking to shape program details.
