Using flywheel systems allows for load balancing - adding power when production levels fall below the demand for power, and then storing excess when the production level exceeds that demand. Otherwise, power utilities need to use other methods, such as gas turbine power plants to adjust the power level.
Beacon Power has installed its second megawatt-sized, flywheel-based energy storage system connected to the grid in New England, and is providing energy storage and load balancing for the New England ISO.
This first made news on EcoGeek a couple of years ago when Beacon first sought approvals for grid connection. Now, they have had one system installed and operating since last fall and have a second system now part of the grid infrastructure. At present, these represent only a tiny fraction of a percent of even just the production capacity of the New England grid. But these systems are proving their functional and economic viability, and more of them will find their way onto the forthcoming smart grid in the coming years.
