Prioritizing nuclear power and natural gas over renewable energy is a risky move for Ontario’s energy future

Norman W. Park, The Conversation, 11 Feb 25

The demand for electricity is growing rapidly as the world transitions from fossil fuels to low carbon-emitting forms of energy. However, making this transition will be difficult.

Ontario is projected to require 75 per cent more electricity by 2050, spurred by increasing demand from the industrial sector, data centres, electric vehicle (EV) adoption and households, according to the Independent Electricity System Operator (IESO).

To meet this demand, Ontario Energy Minister Stephen Lecce has proposed transforming the province into an “energy superpower” by aggressively expanding nuclear energy and natural gas while cutting support for wind and solar renewable energy.

This plan was spelled out in a policy directive from Lecce instructing the IESO to consider bids from all energy sources, opening the door to allow bids from natural gas and nuclear energy.

This is a departure from previous policies. Previously, under former Energy Minister Todd Smith, the IESO had stipulated bids for the electrical grid should only be from wind, solar, hydro or biomass.

The Ontario government should reconsider these plans. Non-renewable energy sources are costly, rely on new, expensive technologies, ignore the harm to human health and ignore the consequences for global warming.

Expanding nuclear

A central pillar of the Ontario government’s energy plan is the aggressive expansion of nuclear power. The province has committed to refurbishing 14 CANDU reactors at Bruce, Darlington and Pickering, and has proposed constructing new reactors at Bruce.

Ontario is also the first jurisdiction in the world to contractually build a BWRX–300 small modular reactor project at Darlington, despite not knowing its projected cost.

The cost of this small modular reactor may be much higher than similarly sized solar, wind and natural gas projects. This is unsurprising, given that the costs of nuclear projects are often much higher than projected.

Ontario encountered a similar issue when the Darlington nuclear generating station was constructed. The actual costs of nuclear projects were more than double projected costs and took almost six years longer to complete than projected.

Given these historical challenges and uncertainties, the province’s push for nuclear expansion is a cause for concern.

Opposition to wind and solar

Despite significant cost reductions in utility-scale wind and solar farms, which makes them less expensive than nuclear and fossil fuels in many parts of the world, Ontario’s recent policy directive reduced support for these non-emitting renewable energy sources…………………………………………………………..

Reconsidering Ontario’s energy transition

Ontario’s energy transition must involve supplying more energy to an expanding electrical grid while ensuring it remains reliable and resilient. The current government’s plans to turn the province into an “energy superpower” will commit Ontario to decades of costly expenditures and relies on unproven new technologies.

The government’s proposal to increase natural gas to supply the electricity grid and new buildings will increase the risk of premature death and serious illness to Ontarians and will increase greenhouse gas emission, undermining efforts to combat global warming.

Lecce should reconsider his current policy directive to the IESO. Future bids for the electrical grid should instead be evaluated for their impacts on the health of Ontario residents and climate change.

Ontario’s energy policies should also be guided by knowledgeable experts outside of government, rather than solely by politicians. Establishing a blue-ribbon committee comprising energy scientists and environmental specialists would provide needed oversight and ensure the province’s energy strategy is cost-effective, technologically sound and aligned with climate goals.

Ontario has an opportunity to lead by example in balancing energy needs with environmental and health priorities.  https://theconversation.com/prioritizing-nuclear-power-and-natural-gas-over-renewable-energy-is-a-risky-move-for-ontarios-energy-future-246289
