Ontario is looking to build greater flexibility and resiliency into its power system with the addition of new projects to test storage technologies. Ontario's grid operator, the Independent Electricity System Operator (IESO), has selected storage technologies from five companies that can offer ancillary services to support increased reliability and efficiency of the grid. The five companies are Canadian Solar Solutions Inc., Convergent Energy and Power LLC, Dimplex North America LTD, Hecate Energy and Hydrogenics Corp.
By procuring storage, Ontario will get a head start on testing new technologies to help manage the changing conditions on the power system. The IESO will take the learnings from these new projects, totalling 34 megawatts (MW), to understand how to better manage the day-to-day operation of the power grid using electricity storage.
"Storage facilities on the grid are a real game changer," said Bruce Campbell, President and CEO of the IESO. "Our electricity system was built on the concept that you can't store large amounts of electricity - we produce electricity at the same time as we consume it. Energy storage projects will provide more flexibility and offer more options to manage the system efficiently."
Energy storage can provide considerable flexibility. It can help relieve localized congestion in the transmission system, as well as maximize the output from wind and solar power generators, storing energy when it's available to be used later when it is needed most. It can also correct small variations in electric frequency on the power system and support voltages.
