(ADPnews) - Dec 17, 2010 - Gridflex Energy LLC, a US developer of bulk energy storage projects for clean energy, plans to build a 300 MW wind energy storage project in the US state of Hawaii.
The Lanai Pumped Storage Project is expected to enable the grid of the island state to absorb some 400 MW of wind power although its peak demand capacity is only 1,200 MW.
The pumped-storage technology pumps water from a lower reservoir into an upper one, creating potential power during periods of low demand. During high-demand periods, the water is released down through a turbine to produce energy.
Gridflex will use the ocean as a lower reservoir in its project, thus saving a considerable sum on building a reservoir.
