Ontario to test storage technologies

Ontario’s grid operator will test storage technologies from five companies in an effort to build greater flexibility and resiliency into Canada’s second largest provincial power system.

After an “impartial” and transparent” selection process, the Independent Electricity System Operator (IESO) opted to test technologies from Canadian Solar Solutions, Convergent Energy and Power,  Dimplex North America, Hecate Energy and Hydrogenics Corp.

IESO will take lessons learned from the projects totaling 34MW to understand how to better manage the day-to-day operation of the power grid using electricity storage.

"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," says IESO chief executive Bruce Campbell.

The projects include facilities connected to the high voltage transmission network in southern and northern Ontario, and those linked to the distribution system in southern Ontario.

All successful projects must provide at least one ancillary service to the power grid. These could include regulation service and/or reactive support and voltage control service.

The Ontario government's Long-Term Energy Plan identified the need to move forward with 50MW of energy storage.  The Ontario Power Authority will follow this procurement by the IESO to obtain the remainder of the 50 MW target.
