Pressing concerns about how to integrate large amounts of renewable energy into the grid was the topic at the recently held Electricity Storage Association's Annual Meeting in California. At the meeting, leading companies, manufacturers, utilities and policy developers gathered under the motto "Electricity Storage: Predictable Power in a Cleantech World."

"Grid-scale storage is here now. Storage should be deployed now at the gigawatt (GW) scale...where capacity, ancillary services and energy time-shifting are clearly needed." -- Ed Cazalet, MegaWatt Storage Farms.
