Ontario IESO to Install Energy Storage System

7 MWh Storage Project Slated to Help Ontario IESO Manage a Variety of Grid Conditions Complete Storage System Includes Batteries, Inverters, Controls, Transformers and Switchgear  

GE’s renewable energy business will supply Convergent Energy + Power with a 7 MW-7 MWh battery energy storage system for the Ontario Independent Electricity System Operator. The complete solution features GE’s Mark VI plant control system with SCADA, Brilliance MW Inverters, packaged lithium ion battery modules, medium-voltage transformers and switchgear integration.

The new system is expected to help the IESO balance longer duration voltage and frequency irregularities in the area. 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, and this deal marks the second system to utilize lithium ion battery modules. Last month, the company announced it would support Con Edison Development with an energy storage project in California.

The deal includes delivery of all equipment and installation support plus GE performance guarantees. Commercial operation is expected to begin in the fall of 2016.
