General Electric (GE) says it will supply Convergent Energy + Power with a 7 megawatt-hour (MWh) battery energy storage system for the Ontario Independent Electricity System Operator (IESO). The system includes GE’s Mark VI plant control system with SCADA, inverters, packaged lithium ion battery modules, medium-voltage transformers and switchgear integration.

“The project utilizes reliable GE equipment and products ranging from enclosures through the point of utility interconnection,” says Frank Genova, COO of Convergent Energy + Power.

The system is expected to help the IESO balance longer-duration voltage and frequency irregularities. While it was engineered primarily to provide ancillary power services—including voltage control, reactive power support, frequency regulation and ramp rate control—the control system also offers energy-related services such as peak shaving and load shifting, depending on the IESO’s needs.

GE recently expanded its energy storage portfolio. This deal marks the second system to use its lithium ion battery modules, which includes delivery of all equipment and installation support plus GE performance guarantees. Commercial operation is expected to start in the fall of 2016.
