Ontario is working toward filling all of the province’s quickly growing electricity needs with emissions-free sources, including a plan to secure new renewable generation, but isn’t quite ready to commit to a moratorium on natural gas.
Energy Minister Todd Smith announced Monday a strategy to prepare the grid for 2030 to 2050 – the Independent Electricity System Operator projects Ontario’s electricity demand could double by mid-century – and next steps involve looking for new wind, solar and hydroelectric power.
“While we may not need to start building today, government and those in the energy sector need to start planning immediately, so we have new clean, zero-emissions projects ready to go when we need them,” Smith said in Windsor, Ont.
The strategy also includes two nuclear projects announced last week – a new, large-scale nuclear plant at Bruce Power on the shore of Lake Huron and three new small modular reactors at the site of the Darlington nuclear plant east of Toronto.
Those projects, enough to power six million homes, will help Ontario end its reliance on natural gas to generate electricity, said Smith, but committing to a moratorium in 2027 and eliminating natural gas by 2050 is contingent on the federal government helping to speed up the new nuclear facilities.
“Today’s report, the Powering Ontario’s Growth plan, commits us to working towards a 100 per cent clean grid,” Smith said in an interview.
“Hopefully the federal government can get on board with our intentions to build this clean generation as quickly as possible … That will put us in a much better position to use our natural gas facilities less in the future, if we can get those new projects online.”
The IESO has said that natural gas is required to ensure supply and stability in the short to medium term, but that it will also increase greenhouse gas emissions from the electricity sector.
The last round of procurements Smith announced for electricity generation involved both natural gas and battery storage projects. The new planned procurement of green power, including wind, solar, hydroelectric and biogas, will pair well with recent energy storage procurements, Smith said, so that power generated by solar panels, for example, can be stored and injected into the system when needed.
Ontario is also looking at two new pump storage projects, in which water is pumped into a reservoir when electricity demand is low, then released through a turbine to generate electricity when demand is higher. Pump storage can dispatch energy for eight hours, versus four for current battery storage, Smith said.
Critics say Ontario wouldn’t be in as much of an electricity supply crunch if the Progressive Conservative government hadn’t cancelled 750 green energy contracts during its first term.
Smith said it was a necessary move at the time.
“We had to cancel those projects when we did,” he said. “We had an oversupply of electricity. Demand in the province was flat for 18 years. We were bleeding manufacturing jobs to other jurisdictions and we were paying way over the market price for those projects.”
Anger over rising hydro bills was high when the former Liberal government lost the election in 2018, going from a majority to not enough seats needed for official party status in the legislature.
The Liberals had given power producers long-term contracts at above-market rates in order to ensure a steady supply, but it meant that rates for consumer rose dramatically while the average electricity market price dropped.
