The Challenges

Major cities and regions, such as Toronto, Ontario, are facing the increasingly difficult challenge of generating more clean and efficient power for their growing population centers while maintaining the reliability of the grid. Coal and nuclear use are trending downwards, while the marketplace for renewables is growing rapidly. But how do you store and leverage renewables to bring stability to an increasingly stressed grid ?
That’s the challenge faced by the IESO, Ontario’s Independent Energy Systems Operator. IESO oversees the wholesale power market and manages the transmission system for Ontario province – matching supply and demand and providing balance and stability for the grid. The stakes are high. Ontario is home to Toronto, the largest city in Canada and the fourth largest in North America spanning 630 square kilometers.

  • Ontario has 35,221 MW of installed generation on its system.
  • Historic power combo of nuclear, hydro and natural gas.
  • Intermittent wind & solar are growing rapidly, adding 3,340 MW since 2010.
  • Renewables continue to expand, with total intermittent wind & solar to reach 7,730 MW in 2018, representing up to 30-50% of the active power supply at any time
  • The high-level intermittent power creates significant grid management challenges for IESO.

The Solution

Leclanché, in partnership with Deltro Energy (Canada), has completed the first of two phases of its BASIN-IESO project in 2018, representing 4 MW / 14 MWh of capacity. Leclanché supplied all battery energy storage systems, the power conversion systems and was the overall EPC contractor. After completion of Phase 2, the project will increase to 30 MW / 20 MWh.
The BASIN-IESO project storage capacity provides grid ancillary services (reactive power, voltage support and frequency regulation) to the IESO, Toronto Hydro and other market participants.

  • As known, the intermittent nature of renewable energy resources, such as wind and solar, can force electrical grids to operate in unfeasible conditions. In order to evaluate the best possible way to overcome this challenge and develop innovative grid solutions, the country founded the Swiss Competence Center of Electrical Infrastructure (SCCER-FURIES).

  • Commercial and Industrial (C&I) electricity customers worldwide are facing pressure to reduce their energy costs. In an increasingly competitive business environment, minimizing and optimizing energy consumption is paramount to being successful.

  • The 35.6MW solar energy plant and 44.2MWh battery storage facility is being built in the Basseterre Valley on the island of St. Kitts. SKELEC, St. Kitts electricity utility, is able to make the transition from diesel to renewables in part thanks to cutting-edge technologies.
