Clean Electricity Production & Investment Credits – Price/Demand-Based Extension (S4175)

Current understanding

S4175 would amend the Internal Revenue Code to extend the clean electricity production credit (IRC §45Y) and clean electricity investment credit (IRC §48E) — both enacted under the Inflation Reduction Act — by tying continued eligibility to increases in electricity prices and demand rather than the current emissions-based phaseout schedule. Under current law, these technology-neutral credits begin phasing down once U.S. power-sector greenhouse gas emissions fall to 25% of 2022 levels or in 2032, whichever is later. If enacted, clean electricity developers and investors would benefit from a longer or more predictable credit window in periods of rising electricity costs and load growth; the fiscal cost would fall on general revenues.
