EnerSys recently announced that it is entering the large-scale energy storage market with its new OptiGrid Stored Energy Solutions, a turnkey megawatt hour scale energy management system for utilities and large industrial applications.
John D. Craig, company CEO, remarked that the opportunity comes from a forecast large-scale energy storage growth over the next 10 to 20 years of as much as US$200-600 billion, globally. He added that the company believed that it could reach two to four gigawatts as soon as 2016.
