Governor Jared Polis of Colorado signed HB26-1226 this week—a landmark piece of legislation designed to shield the state from the escalating costs and pollution tied to the Trump administration's federal orders forcing coal plants to remain operational beyond their scheduled retirement dates. The bill, formally titled the Manage Emissions from Electric Generating Units law, represents one of the clearest state-level pushbacks against what environmental advocates are calling federal overreach into Colorado's energy future.
The context is urgent. The Trump administration has been issuing 202(c) orders nationwide that compel coal plants to stay online indefinitely, defying utilities' own retirement plans and state clean energy targets. According to a Sierra Club analysis, these orders have already cost Americans over $330 million, with those expenses landing directly on ratepayers and surrounding communities—many of them low-income and communities of color already burdened by coal plant pollution.
HB26-1226 operates on three fronts. First, it mandates transparency: utilities and operators must now clearly document the costs of keeping coal plants running beyond their intended retirement dates, preventing hidden expenses from silently accumulating on Coloradans' energy bills. Second, it requires the state's Public Utilities Commission to approve new resources that move Colorado toward its 2030 climate targets, ensuring the state has a roadmap to continue its clean energy transition even if some coal plants are forced to linger. Third, it sets a firm line: any coal plant still operating after 2033 must install modern pollution controls, sharply reducing emissions of harmful pollutants like nitrogen oxides and sulfur dioxide.
The Craig 1 coal unit offers a stark example of the stakes. Experts and utilities determined the unit was not needed to meet any genuine emergency demand, yet following two executive 202(c) orders, it has continued burning coal at unclear cost—and it remains uncertain who will ultimately pay the bill for power that wasn't actually needed. Sierra Club, Colorado's Attorney General, and two of Tri-State's owners have all filed lawsuits against what they call the illegal federal order.
For Colorado communities—especially those surrounding coal plants that have long endured disproportionate air pollution—the law promises immediate relief. Margaret Kran-Annexstein, Director of Colorado Sierra Club, emphasized that the legislation supports "a just transition that supports coal communities and local workers while reducing climate and air pollution." Rep. Meg Froelich, one of the bill's sponsors, put it plainly: "Coal isn't an energy affordability solution, and the Trump administration is only making this problem worse by forcing plants to stay open."
The bill's passage reflects a broader tension between state climate ambitions and federal intervention. Colorado has committed to clean energy goals and strategic coal retirements, investments that federal orders now threaten to undermine. By requiring transparency and mandating emissions controls, HB26-1226 doesn't block the federal orders—it can't—but it ensures Colorado doesn't absorb those costs passively and continues its path toward a clean energy economy despite Washington's interference.
As Paul Sherman of Conservation Colorado framed it, the state's action shows what leadership looks like when local decision-makers refuse to sacrifice their communities' air quality and energy affordability to protect coal industry profits. Governor Polis's signature this week signals that Colorado intends to keep rolling forward on its clean energy transition—federal orders or not.
