EnerSys opens energy management facility to utilities Energy Storage Journal

A demonstration site to show how utility scale energy storage operates is up and running in Burlington, Vermont, in the US.
The site houses OptiGrid, a turnkey MWh scale energy management system for utilities and large industrial applications, launched by EnerSys in late 2012.
EnerSys, the world’s largest battery maker and supplier, developed OptiGrid in a bid to capture a share of the large scale energy storage market, which could reach 4 GW by 2016 and could be worth $600 billion in the next 20 years.
The OptiGrid demonstrator was built with private funds from EnerSys and will show utilities that large battery storage installations are safe, stable and reliable. OptiGrid can be used for a range of applications, including peak shaving, time shifting, arbitrage as well as PV and wind power integration into the grid.
The Burlington plant is attached to a factory belonging to EnerSys’ inverter partner Dynapower and is able to provide power for the facility in times of high demand rather than the factory having to shut down operations for periods of time when electricity demand is high as part of energy curtailment practices. Enersys is able to focus on the DC side to ensure that the battery storage is being optimised and is safe while Dynapower is focusing on the AC side. The batteries used are valve regulated lead acid.
By supplying OptiGrid as a turnkey energy management system, Enersys will be able to use its track record in various battery chemistries and marry the appropriate battery-based storage to specific application’s electrical load profile. In the US utilities in different regions tend to have specific needs for storage. In the Midwest a big issue is integrating wind power into the grid smoothly, while in California, the integration of high concentrations of solar PV integration in some areas is placing pressure of the grid. On the east coast, though renewables integration is comparatively low, there is interest in using storage for peak shaving to shift power consumption demand. Utilities can visit the EnerSys demonstration to see large-scale energy storage and management in action.
There are several functions designed to ensure safety of OptiGrid’s battery components, including the system’s ability to disconnect on command into several strings for safety and maintenance as well as DC ground fault monitoring and protection. EnerSys also provides up to 100% project financing for OptiGrid and is able to lease OptiGrid to customers and users as part of a turnkey service that includes batteries, battery management systems and monitoring, shelter and financing.
