NEPA Reform and the SPEED Act: Accelerating Clean Energy Permitting in the U.S.

NEPA Reform and the SPEED Act: Accelerating Clean Energy Permitting in the U.S.

The National Environmental Policy Act (NEPA), enacted in 1970, has long served as the foundation of U.S. environmental law, requiring federal agencies to assess the environmental impacts of significant projects before approval. While the law has ensured stronger environmental accountability, its processes have often been criticized for being lengthy and complex. At a time when the U.S. aims to scale up renewable energy and modernize the electric grid, these delays pose a significant challenge. The proposed Standardizing Permitting for Expediting Economic Development (SPEED) Act represents a bipartisan effort to reform permitting timelines, streamline reviews, and support faster energy development. This blog examines what these reforms could mean for utilities, businesses, and the broader clean energy transition.

NEPA Reform and the SPEED Act: Accelerating Clean Energy Permitting in the U.S.

The Case for Reform

Permitting reform has emerged as a critical element of U.S. climate and energy policy. According to federal data, the average Environmental Impact Statement (EIS) under NEPA takes approximately 4.5 years to complete, with some cases extending beyond a decade. These delays often stall projects essential for decarbonization, including renewable generation facilities and new transmission lines. Electric utilities, represented by groups such as the Edison Electric Institute (EEI) and the National Rural Electric Cooperative Association (NRECA), have expressed strong support for reforms that would make timelines more predictable and efficient. For corporations pursuing ambitious Scope 2 emissions targets, permitting delays directly limit the availability of clean energy options, raising both costs and risks in power procurement strategies.

What the SPEED Act Proposes

The SPEED Act is designed to simplify and accelerate permitting without entirely discarding environmental safeguards. Its key provisions include setting statutory deadlines of two years for Environmental Impact Statements and one year for Environmental Assessments. It also seeks to narrow the definition of federal actions that trigger NEPA review, thereby exempting smaller or lower-risk projects from full-scale assessments. Additionally, the bill proposes stricter limits on judicial review timelines to minimize litigation-related delays. While utilities and bipartisan lawmakers argue this would help address the infrastructure bottleneck, legal scholars note that the Council on Environmental Quality (CEQ) already issued updated NEPA guidance in 2023, raising questions about whether additional reforms are necessary or duplicative.

Opportunities and Risks for the Clean Energy Transition

Streamlined permitting could present major opportunities for the clean energy sector. Faster approvals may reduce uncertainty and unlock capital for renewable projects, ultimately leading to more affordable corporate power purchase agreements (PPAs). The SPEED Act could also accelerate transmission development, which is vital for integrating renewable energy at scale. However, critics warn that accelerating reviews risks undermining the thoroughness of environmental assessments and reducing opportunities for public participation. There is also concern that rushing projects could lead to legal disputes, especially given recent Supreme Court rulings that affect administrative authority. The challenge lies in finding a balance where permitting is expedited without eroding the environmental and social safeguards that give projects legitimacy and community support.

Conclusion

Permitting reform sits at the heart of U.S. energy and climate policy. The SPEED Act highlights bipartisan recognition that current processes are too slow to support the pace of clean energy deployment required to meet national goals. Yet, the ultimate test of reform will be whether it can deliver faster approvals while maintaining trust, accountability, and rigorous environmental protections. For utilities, corporations, and policymakers alike, the future of NEPA reform will determine how quickly the U.S. can expand renewable generation, strengthen its grid, and reduce Scope 2 emissions. The path forward requires striking the right balance between speed and responsibility.
