Americans for a Clean Energy Grid (ACEG) is the only non-profit broad-based public interest advocacy coalition focused on the need to expand, integrate, and modernize the North American high-voltage grid.
Expanded high-voltage transmission will make America’s electric grid more affordable, reliable, and sustainable and allow America to tap all economic energy resources, overcome system management challenges, and create thousands of well-compensated jobs. But an insular, outdated and often short-sighted regional transmission planning and permitting system stands in the way of achieving those goals.
ACEG brings together the diverse support for an expanded and modernized grid from business, labor, consumer and environmental groups, and other transmission supporters to educate policymakers and key opinion leaders to support policy which recognizes the benefits of a robust transmission grid. ACEG is a 501(c)(3) organization.


ACEG’s mission is to educate stakeholders and the public to support policies and regulations favoring the expansion, modernization, and integration of the high-voltage electric transmission grid in order to achieve a clean energy economy—one that attains the scientifically-validated global objective of reducing greenhouse gas emissions by 80%.

ACEG’s diverse stakeholders uniformly recognize the necessity to continue momentum toward a sustainable, decarbonized economy, but also understand that the challenges facing the grid can only be met if there is broad public and policymaker recognition that its many benefits dramatically exceed its costs, and an opportunity to earn a return on the significant investments that will be required.


By 2035, ACEG envisions a grid bringing to reality the potential revealed in the National Renewable Energy Laboratory’s Interconnections Seam Study. Such an “American Super Grid” would save consumers more than $47 billion and return more than $2.50 for every dollar invested, according to the study. It would create a cleaner, more efficient, and more resilient high-voltage system for all Americans.
The development of an American Super Grid could, among other benefits:

  • Reliably provide 80 percent of America’s electricity from carbon-free sources—an objective which is technically and economically feasible using today’s technology.
  • Allow the growing number of electric utilities, corporate and institutional electricity buyers, and other consumers to meet carbon and clean energy goals affordably and reliably, potentially from currently remote resources.
  • Enable clean electrification of other sectors of the economy, create jobs (especially in rural areas), spur innovation, and create a broader, more transparent power market.

Achieving this vision will require creating a new policy and regulatory environment at the federal, regional and state levels which recognizes the substantial nationwide benefits of this Super Grid, plans for its development, ensures its permitting, and allocates its costs to all who benefit from it.
