By Diane Cardwell, The New York Times. For GSS Energy Use chapter 10. Excerpt: ...As energy policies, technologies and markets shift to encourage the growth of renewable power plants, rooftop solar and decentralized systems like microgrids, storage is gaining more investment and interest while regulators are moving to require its inclusion in renewable energy developments and wholesale electricity markets. ...Whether to smooth out variations in the output from wind and solar farms, feed power to the grid at times of peak demand or store it for use when renewable plants or the grid go down, utilities, islands and big institutions like the military are experimenting with different battery systems and chemistries. ...Battery storage systems are still expensive — running more than $500 per kilowatt-hour installed, a price that government agencies estimate must fall to roughly $100 to $150 to spur widespread adoption. But they already make financial sense for certain customers in expensive markets like New York and California, as well as for utilities in states with high concentrations of wind and solar, said Paul Albertus, a program director who focuses on energy storage at the Advanced Research Projects Agency-Energy. ...National Grid is planning to work with Vionx in battery installations early next year at a high school with a wind turbine and at a solar farm the utility owns in Massachusetts....  http://www.nytimes.com/2015/10/26/business/energy-environment/energy-storage-industry-gaining-momentum.html
