WINNIPEG — Manitoba Hydro faces a detailed public examination starting Monday as the Public Utilities Board begins six weeks of hearings into the Crown corporation’s 10-year integrated resource plan and a proposal that includes $3 billion in natural gas-fired combustion turbines.
What’s at stake
The hearings come as Hydro grapples with an ageing system, a projected capacity shortfall and mounting debt. The utility has signalled it may need to add about 1,760 megawatts of capacity over the next decade with an eye toward a net-zero grid by 2035. At the same time, Hydro’s balance sheet shows a debt load of roughly $25 billion.
The regulator will examine Hydro’s analysis of future demand, the timing and mix of new resources, and whether the proposed plan represents the most prudent and least-cost approach for customers. The Public Utilities Board will later provide recommendations to government on the combustion turbines and the broader plan.
Stakeholders gearing up
Seven parties were granted intervener status to present evidence and challenge Hydro’s assumptions. Among them is the Consumers Coalition, represented by the Public Interest Law Centre, which has retained experts to scrutinize the utility’s modelling and options.
“Independent expert evidence suggests Manitoba Hydro’s plan falls short of best practice IRP (integrated resource plan) and may lead to building too much too soon,” said Katrine Dilay, an attorney with the Public Interest Law Centre.
The Consumers Coalition acts to protect residential customers and has signalled it will press for alternatives that could include greater emphasis on conservation, demand-side measures, and different resource mixes.
Key figures in the plan
| Metric | Value |
|---|---|
| Projected shortfall in firm capacity by 2030 | ~600 MW |
| Proposed combustion turbine cost | $3 billion |
| Planned capacity additions | 1,760 MW |
| Debt (approx.) | $25 billion |
| Net-zero target for grid | 2035 |
Areas of contention
Critics say the plan may favour overbuilding and lock the province into carbon-emitting infrastructure at substantial cost. Proponents, including Manitoba Hydro spokespeople, argue the plan balances reliability, affordability and environmental considerations using the best available information.
Hydro projects a potential shortfall in firm electricity capacity of about 600 megawatts by the end of 2030. That projected gap underpins the urgency behind proposals such as the combustion turbines and discussions around enhanced wind and other renewable resources, including partnerships with Indigenous communities.
- Reliability: Hydro emphasises the need to ensure electricity remains dependable during extreme weather and peak demand.
- Cost control: The scale and timing of new builds will shape future rate pressures for residential and commercial customers.
- Environment: The province’s net-zero goal by 2035 raises questions about adding gas-fired generation versus renewables and conservation measures.
Next steps and public interest
The PUB hearings will run for approximately six weeks, during which interveners and Hydro will present evidence and cross-examine experts. The board’s findings and recommendations to government will be closely watched by municipalities, industry, First Nations and residents concerned about future rates and energy security.
Beyond technical modelling, the debate will involve practical choices: whether to prioritise rapid additions of dispatchable capacity such as turbines, invest more heavily in energy efficiency, accelerate Indigenous-led wind projects, or pursue a different combination of resources. The outcome will shape Manitoba’s electricity landscape for decades and influence provincial finances and climate commitments.
As the hearings unfold, consumers and community groups will have opportunities to follow the process and submit concerns through the PUB. The board’s assessment will be pivotal in determining whether Hydro’s preferred path is adopted, modified or replaced with alternatives recommended by interveners.
This review marks a critical moment for Manitoba’s energy future — balancing the immediate need to avoid capacity shortfalls with longer-term goals around affordability and decarbonisation.
