House Energy panel asks PUC to propose revised 'single plant' definition for S 50, sets November report deadline

Wolf Meck, House Energy and Digital Infrastructure, opened the April 17 meeting by proposing an addition to S 50 asking the Public Utility Commission to develop and submit a proposed amended definition of “plant.”

Ellen Tchaikovsky, Legislative Council staff, read draft language that would require the PUC "on or before 11/01/2025, and with input from stakeholders, [to] submit a proposed amended definition of plant in 30 DSA section 8002 18 to the House Committee on Energy and Digital Infrastructure and the Senate Committee on Natural Resources and Energy." Tchaikovsky said the commission should consider "the land use benefits of colocation of energy generation facilities, the ability to ensure comprehensive review of colocated facilities, and the potential impacts to rate payers associated with colocated facilities."

The directive would make the PUC’s proposal a starting point for the committee to consider in the next session. "Whatever the PUC comes back with on November 1...simply becomes the starting point for another round of testimony and conversation," said a committee member.

Why it matters: The single-plant definition determines when multiple generation projects on the same site are reviewed together or separately. That distinction affects required infrastructure, permitting, program eligibility and, potentially, ratepayer costs. Committee members and stakeholders said they want a clear definition that encourages co-location of renewables where appropriate while preventing program “gaming.”

Key details from the meeting

- Draft language and deadline: Tchaikovsky read draft 4.1, which asks the PUC to submit recommended statutory language and to report on its stakeholder process by Nov. 1, 2025. The committee asked the PUC to include an explanation of how it arrived at the recommendation.

- Considerations for the PUC: The committee asked the PUC to evaluate land-use benefits of co-location, how to ensure comprehensive review for cumulative impacts when multiple projects share a site, and potential ratepayer impacts tied to program size limits.

- Stakeholder process: A PUC representative said the commission will notify stakeholders, hold workshops (virtual or in person), and accept written comments. "We can...notify all the players in this, all the stakeholders," the PUC representative said, adding the agency regularly runs workshops on energy subjects.

- Industry concerns about specificity: Peter Sterling of Renewable Energy told the committee the proposed directive is a "solid foundation" but "unfortunately a little too vague as far as legislative direction goes," arguing the PUC needs clearer statutory guidance to produce the intended results. Sterling suggested the PUC be given objective criteria, such as facilitating colocation up to a stated cumulative capacity (he referenced "up to 10 megawatt in cumulative capacity" as an example) and minimizing redundant infrastructure.

- Batteries and other equipment: Committee members asked whether battery storage would be included in the single-plant definition. A PUC representative answered that battery projects file CPGs and have a separate review path under a different chapter, and typically are not currently considered part of the single-plant definition used for solar facilities.

Committee direction and next steps

- The committee asked Legislative Council to insert the PUC report-back language into S 50. Ellen Tchaikovsky agreed to add a few words asking the PUC to include an explanation of its process and supporting data.

- The committee scheduled a final committee vote on the bill next Friday and indicated the bill would be posted and shared with the Senate; the chair said she will serve as floor reporter and requested time to prepare.

Ending

The committee concluded that asking the PUC to develop recommended statutory language and to report back with stakeholder input would allow the panel to take up a more detailed proposal in the next session. Members set a committee markup vote for next Friday and said they would post the final draft and notify the Senate before the bill moves to the floor.
