Next generation energy storage site to enhance grid stabilisation


Enbridge Gas Distribution, together with Hydrogenics Corporation are now providing regulation services under a contract with the Independent Electricity System Operator (IESO) of Ontario, Canada.

This project was originally awarded as one of several technology applications selected by the IESO for power grid stability and reliability services in the province.

Regulation service is an important reliability function that corrects for short-term changes in electricity use and helps compensate for real-time supply and demand imbalances.

The Enbridge-Hydrogenics 2.5MW facility was designed and built on a 5MW scalable platform and features the PEM electrolyzer technology, which has the highest power density and smallest footprint of any such system in the world.

Daryl Wilson, president & CEO of Hydrogenics, stated, “We are very excited to have this latest, multi-megawatt Power-to-Gas facility up and running – here in our own back yard – providing the IESO with a fast-responding resource to enhance the flexibility and reliability of operating the grid. Drawing on our experience of providing large scale energy storage facilities in Europe, this new operation, managed with Enbridge, will be a showcase for our advanced technology in North America. With Markham up and running, Hydrogenics has now delivered over 25MW of energy storage capacity using our Power-to-Gas expertise.”

“I’ve worked in the energy sector my entire career and this is one of the most exciting projects in which I’ve ever been involved,” said Jim Sanders, president, Enbridge Gas Distribution. “I’m proud to see a Canadian company leveraging world-class Canadian technology to solve current energy challenges. Today is a major milestone for Enbridge and Ontario’s energy sector.”

This project is another example of how the company’s power-to-gas technology is transforming the energy sector through the production of renewable hydrogen for zero-emission fuel cell electric vehicles (train, bus and truck fleets) or other applications while providing grid services to System Operators.
