You'd probably need more batteries than would be economically feasible in that precise setup. But a similar scheme is used with electric water pumps and hydroelectric turbines. It's called pumped hydro:

- maxerickson 9y agoGrid batteries are starting to come online. A somewhat special case is Fairbanks (which is isolated, so the economics kick in earlier): http://www.windpowerengineering.com/design/electrical/battery-stores-40-mw-for-ankorage-emergencies/ http://www.windpowerengineering.com/design/electrical/batter... A much larger installation is planned in China (different tech too): http://www.engineering.com/DesignerEdge/DesignerEdgeArticles/ArticleID/12312/Massive-800-MegaWatt-hour-Battery-to-Be-Deployed-in-China.aspx http://www.engineering.com/DesignerEdge/DesignerEdgeArticles... There are also some megawatt-hour scale lithium-ion experiments at substations.

- 205guy 9y agoThere is also a Tesla/SolarCity solar+battery plant in Hawaii that opened earlier this year and is currently operational. It is 13 GWh and 52 GW, thus it provides 13 GW of stored solar energy for 4 hours after the sun goes away. http://thegardenisland.com/business/energy/kiuc-opens-new-megawatt-hour-solar-farm/article_29e735ee-6cbc-5f64-b8d0-d34778144fb8.html?mode=jqm http://thegardenisland.com/business/energy/kiuc-opens-new-me...
