Committee debates SB418 microgrid tax credit; bill held for possible tax package

Senators and witnesses spent more than an hour on Senate Bill 4 18, a measure that would create a qualified-microgrid tax credit and other legal definitions intended to accelerate construction of localized power systems. Sponsor Senator Padilla described the bill as a tool to “incentivize the construction and installation of microgrids in underserved communities” and said the credit amount in the draft is $100,000 per microgrid.

The bill’s committee substitute incorporated multiple edits requested by investor-owned electric utilities and by committee members. Those changes removed distribution cooperatives from eligibility, added an explicit authorization for electric public utilities to acquire self-source generation resources (while preserving existing Public Regulation Commission approval processes), clarified definitions for “self-source generation resources,” and added a net-zero emissions standard for qualified microgrids by 2050. Sponsor Padilla and bill counsel said the intent is that the bill “complements” and does not amend the Energy Transition Act (ETA).

Supporters said the credit would help secure private investment and bring power online more quickly for major economic projects. Alicia Keys, a Borderplex Digital partner and former New Mexico Economic Development secretary, said the bill would provide the “legal certainty” needed for a recently announced $5 billion Borderplex project and argued the microgrids would be paid for by industry rather than ratepayers. Utility witnesses including Rico Gonzalez of El Paso Electric, Mike D’Antonio of Xcel Energy and Carlos Lucero of the Public Service Company of New Mexico told the committee they supported the substitute after the utility-driven clarifications were added.

Opponents — including Sierra Club Rio Grande chapter director Camilla Feibelman, energy engineer Athena Cristadulu, and Richard Barish — warned the measure could be used to support new fossil-fuel baseload plants or other nonrenewable infrastructure if offsets and “net-zero” language are interpreted to allow fossil emissions plus later offsets. Feibelman said “we cannot just look at 2050; we have to make sure we look at the journey along the way” and urged tighter restrictions on new fossil infrastructure. Committee members repeatedly pressed sponsors and experts to clarify how the bill would interact with the ETA and with Public Regulation Commission (PRC) jurisdiction when private microgrids sell excess power back to an investor-owned utility.

Committee debate produced several technical amendments and a proposal from Senator Figueroa to add PRC review language. The committee accepted two clarifying edits to make PRC oversight explicit for any sale into the public grid and to finalize the net-zero sentence punctuation; a separate suggestion to replace “net zero” with a numeric percentage failed. Senator Bergman moved the committee substitute for discussion. The sponsor and witnesses emphasized the bill would not exempt qualifying microgrids from the ETA: “All electrons that go to a public utility are still subject to the ETA,” bill counsel said.

Outcome: Committee members did not take a final vote to report SB418 for passage; the chair said the measure is being held for possible inclusion in a later tax package. The record shows a committee substitute was moved for discussion, and the bill was left pending.

Why this matters: Supporters say microgrids could speed power availability for large economic-development projects and increase local renewable deployment; opponents worry the draft could be used to justify new fossil infrastructure through offsetting schemes and therefore weaken the ETA’s goals. The committee’s actions preserved the bill for later negotiation while adding clarifications about PRC review and emissions standards.

Provenance: Transcript excerpts: “I essentially, s b 4 18 establishes the micro qualified microgrid bridal tax credit…provides eligibility criteria…the tax credit amount of $100,000 per microgrid” (Senator Padilla presentation); “we added a net 0 requirement…by the year 2050…the total direct greenhouse gas emissions reduced or produced by qualified microgrids shall achieve a net 0 standard” (committee substitute explanation); “all electrons that go to a public utility are still subject to the ETA” (bill counsel).
