Powering the Future

This session explains new U.S. Department of Energy efficiency standards for future distribution transformers and examines how those requirements affect electricity costs and emissions. The presentation visualizes U.S. transformer market research, highlighting key demand drivers, material constraints and supply-chain impacts. It also presents modeling results that show how higher efficiency requirements change transformer designs, including size, materials and performance tradeoffs. Finally, the session quantifies the cost of inefficiency in both financial and emissions terms, detailing annual impacts as well as total cost of ownership.
