Distributed Energy Resources Requirements
HB1225, titled the "Advancing Grid Resilience Using Distributed Energy Resources Act," makes a series of changes to Colorado law intended to speed deployment of distributed energy resources, especially community solar, dispatchable distributed generation, and energy storage. The bill’s legislative findings emphasize rising electricity demand, the need for grid reliability and affordability, and the role of distributed resources in serving customers who cannot install on-site generation, including low-income subscribers. It also cites federal tax policy changes and interconnection delays as reasons for updating state policy.
The bill would revise the community solar garden statutes to allow, beginning October 1, 2026, a subscriber organization to provide income-qualified subscribers with a fixed bill credit while other subscribers receive an annually changing credit. The fixed credit would be initially selected from one of the prior three years’ values and then adjusted over time by the Public Utilities Commission. The bill also clarifies definitions related to income-qualified subscribers and updates the treatment of dispatchable distributed generation to include standalone energy storage systems.
A major portion of the bill focuses on interconnection. It limits when utilities can require customers to pay for interconnection facilities and upgrades, allows utilities to recover prudently incurred costs for interconnection-related equipment, and requires large utilities to convene a working group to accelerate distributed generation interconnection. That working group must consider cluster or batch study processes, surety bonds instead of letters of credit or cash, and third-party interconnection studies and upgrade work. The bill also sets rules for third-party contractors, including utility approval, inspection, documentation, safety and reliability standards, and a clear allocation of liability and repair costs to the contractor rather than the utility or ratepayers.
HB1225 further directs the Public Utilities Commission to revise or clarify rules for aggregation and interconnection of retail distributed generation, including size and installation requirements for off-site renewable distributed generation or storage facilities used in net metering. It also requires the commission to evaluate those size and installation limitations in a future renewable energy standard compliance plan. The bill takes effect after the referendum period unless referred to voters.
The overall sentiment appears generally favorable, as reflected in strong committee and floor votes in both chambers and the bill’s advancement through the legislative process. At the same time, the recorded votes show some opposition, especially at the House Committee of the Whole stage and on third reading, suggesting disagreement over the scope of utility obligations, interconnection reforms, and ratepayer impacts. The main points of contention appear to be whether the bill appropriately balances faster deployment and consumer benefits against utility cost recovery, reliability, labor, and safety concerns, particularly with third-party contractors and changes to bill-credit structures for community solar subscribers.
The bill amends multiple provisions of Colorado’s electric utility statutes, including community solar gardens, retail distributed generation interconnection, dispatchable distributed generation, and renewable energy standards rules. It gives the Public Utilities Commission additional direction to update rules, requires large utilities to create an interconnection working group, changes how certain bill credits are structured for income-qualified community solar subscribers, and expands the definition of dispatchable distributed generation to include standalone storage. It also affects utilities, project developers, subscriber organizations, electricians, and interconnection customers by changing cost recovery, security, contractor, and compliance requirements.
The bill appears to have broad support for its goals of improving grid resilience, accelerating distributed energy deployment, and preserving benefits for low-income subscribers, as shown by its passage through committee and approval on third reading in both chambers. However, the non-unanimous votes indicate meaningful reservations among some legislators. The opposition likely reflects concerns about utility regulation, implementation complexity, cost allocation, and whether the bill’s interconnection and third-party contractor provisions could create reliability or safety risks.
The most notable disagreements center on interconnection reform and cost responsibility. Some legislators appear to have questioned the bill’s requirements for utilities to use third-party contractors, accept alternative forms of security, and delay charging customers for interconnection costs until shortly before those costs are incurred. Another area of tension is the bill-credit change for income-qualified subscribers, which is designed to preserve value over time but may raise questions about fairness, administrative complexity, and utility accounting. There is also likely concern about how the bill affects ratepayers, utility reliability obligations, and labor or technical standards for third-party work.
