Definitive Solar Institute

A community for solar development professionals.

Utility-Scale Electricity Storage Systems

Tuesday, October 11, 2011 11:00am - 11:30am EDT  
Host: Definitive Solar Institute
By: Tom Mason, CEO, Gravity Power

Gravity Power will discuss its energy storage power plants in comparison to combustion turbine plants and other storage for peaking and ancillary services power. The “Gravity Power Module” (GPM) hydraulically lifts a massive piston inside a deep vertical shaft to store energy, and releases the piston on demand to force water through a hydro turbine. Early units will supply 40-150 MW for 4 hours or more. The Company plans to sell turnkey plants, operate and maintain and joint venture or license technology in strategic markets. It is working with developers in Texas, California, New York, the Mid-East, South Africa, India, China, Turkey, France, Germany and Mexico to progress demonstration projects and commercial installations, the first to be completed in 2013.
