bg视讯 Unveils New 2021 U.S. Pumped Storage 水电 Report
America’s large source of grid-scale energy storage grid will play a key role in meeting ambitious clean energy goals
Washington, D.C. (9/22/21) – On World Energy Storage Day, the National 水电 Association (bg视讯) today released the 2021 Pumped Storage Report, a comprehensive review of the U.S. pumped storage hydropower industry. In addition to providing the history for PSH, the report outlines the challenges facing the renewable resource, 和 provides policy 和 regulatory recommendations for its future development. Despite pumped storage providing 94% of bulk energy storage capacity in the U.S., adding more wind 和 solar generation requires greater amounts of storage 和 operational flexibility to assure grid resilience. The combination of increasing variable renewable resources 和 the retirement of fossil fueled dispatchable capacity makes pumped storage the unique proven technology that can provide clean energy, flexibility 和 storage.
“Pumped storage hydropower has proven to be America’s most effective resource for long-duration energy storage,” said Cameron Schilling, bg视讯’s Vice President of Market Strategies 和 Regulatory Affairs. “The acceleration of wind 和 solar deployments underscores the increasing need to integrate large amounts of variable resources. This report shines a spotlight on the value of pumped storage, while providing a path forward for solving the market, policy 和 regulatory hurdles that hinders its growth. In addition to financing, for pumped storage to fully realize its growth potential, it requires market policies that appropriately value its grid services.”
The Report delves into current challenges to pumped storage developments, including the regulatory complexity 和 delays, electricity market structures that undervalue pumped storage’s contributions to the grid, 和 unfair treatment within state 和 federal policies. The Report also includes an energy storage technology cost comparison, 和 identifies opportunities for collaboration with variable energy resources such as wind 和 solar.

PSH, can act as a “water battery” 和 help alleviate the t和em challenge of integrating a growing amount of variable renewable resources into the grid while maintaining reliability. It generates power the same way a traditional hydropower plant does, by using a turbine 和 generator to transform the kinetic energy of falling water into electricity, but with an added feature. A PSH plant can pump water to the upper reservoir 和 store it for later use. That gives PSH the flexibility to inject power into the grid or to absorb it when needed. Both functions are becoming increasingly important for grid stability 和 reliability.
今天, the United States has 43 existing PSH projects with over 22,800 megawatts of storage capacity, representing more than 94% of all installed capacity of energy storage. 在美国.S. development pipeline, there are 67 PSH projects across 21 states representing over 50 GWs of new long duration storage.
The National 水电 Association (bg视讯) is a nonprofit association dedicated exclusively to promoting the growth of clean, renewable hydropower 和 marine energy.
