The United States’ renewable energy sector is entering a new phase as changes to federal tax credits impose tighter deadlines and stricter eligibility requirements for wind and solar projects, according to GlobalData.
GlobalData’s report, North and South America Renewable Energy Policy Handbook 2026, says the One Big Beautiful Bill Act, enacted in July 2025, introduced termination provisions for the Section 45Y Clean Electricity Production Credit and Section 48E Clean Electricity Investment Credit for applicable wind and solar facilities placed in service after December 31, 2027, subject to statutory exceptions.
Mohammed Ziauddin, Power Analyst at GlobalData, said the closure of the initial transition window has made construction schedules, project completion dates and compliance with supply-chain rules increasingly important for developers.
The July 4, 2026 deadline for meeting the beginning-of-construction requirements under the statutory transition provisions has passed. Projects that qualified by that date may retain eligibility under the applicable transition rules, subject to completion and continuity conditions. Other applicable projects generally need to be operational by December 31, 2027, to qualify for the relevant credits.
The revised framework also introduces restrictions concerning material assistance from prohibited foreign entities. Guidance issued by the US Treasury Department and the Internal Revenue Service in February 2026 outlines requirements affecting certain clean electricity facilities and energy storage technologies.
Developers must therefore assess not only construction and commissioning schedules but also ownership, equipment sourcing and other applicable compliance requirements.
GlobalData noted that federal tax credit changes operate alongside state-level renewable energy policies, including renewable portfolio standards, clean electricity requirements and procurement programs.
The changes apply specifically to the United States and do not establish common deadlines for Canada, Mexico or South American countries, which maintain their own renewable energy policy frameworks.
Ziauddin said developers must understand the interaction between federal tax provisions, project milestones and supply-chain compliance to assess eligibility and investment risks.
