Longview works on 2,000-MW pumped storage project in Arizona

Longview Energy Exchange LLC told the Federal Energy Regulatory Commission on April 30 that it is making progress with the 2,000-MW Longview Pumped Storage Hydroelectric Project in Arizona.

Longview Energy Exchange filed with the commission its fourth six-month update report on this project under a preliminary permit issued by FERC in April 2012. During the most recent six-month period, Longview said it has completed or continued the following development activities:

  • Developed, based on existing preliminary-level layouts of the project site, a preferred alternative for sizing of reservoirs and dams, dam type, basic alignment of tunnels, powerhouse location, and number of pump-generator units.
  • Developed construction cost estimates based on the preferred alternative.
  • Presented a symposium to Arizona and California utilities, prospective project-partners, and utility regulators on April 9-10, 2014, to provide information on project status and opportunities. Symposium presentation materials are attached to the April 30 FERC filing. The attendance list for the symposium shows officials from Southern California Edison, Tucson Electric Power, the Imperial Irrigation District and the Los Angeles Department of Water and Power as among those attending.
  • Attended the California Energy Summit in December 2013 to gain knowledge of the California market, regulations, and key players.
  • Attended California Public Utility Commission Pumped Storage Workshop Jan. 16, 2014, to gain knowledge of pumped storage technologies and current projects.
  • Maintained and grew the Integrated Project Team comprised of hydropower and transmission engineering, utility, energy market, regulatory, environmental, and legal experts.

Over the next six months, the company plans to:

  • Explore detailed agreements with identified project-partners.
  • Continue engineering assessment of project design and configuration.
  • Continue assessment of transmission integration.

The project site is in Yavapai County, Arizona. The project conceptually consists of: six to eight variable speed pumped storage units with a total generation capacity of 2,000 MW; two or three transmission lines interconnecting the project to the existing 500-kV grid; and a daily operational cycle of generating for 10 hours and pumping water uphill for 12-14 hours to be ready for more generation. The presentation indicates the company wants this project in operation in 2021.

The project contact is: Longview Energy Exchange LLC, Mitchell Wexler, Manager, 314-292-5333.
