The Brandon dispatchable capacity project
Manitoba Hydro's name for roughly 750 MW of natural-gas combustion turbines at Brandon, for about $3 billion, in service for 2030. Here is what it is, why it is before the Public Utilities Board, and which parts are genuinely contested.

What it is
The Brandon dispatchable capacity project is Manitoba Hydro's proposal to add combustion turbine units at the existing Brandon generating station, together with transmission and distribution upgrades and a new natural-gas pipeline right-of-way to bring fuel from TC Energy's Canadian Mainline. Hydro's 2025 Integrated Resource Plan recommended 750 MW of combustion turbine capacity, and the project carries a capital cost of roughly $3 billion.
Hydro describes the plant as drought protection and capacity insurance rather than everyday generation: it expects the turbines to run less than 5% of an average year, covering the coldest winter mornings and drought conditions when reservoir output is constrained.
Why it is being reviewed
Manitoba Hydro projects a firm winter capacity shortfall of about 600 megawatts by 2030 in a drought year. The shortfall is real and not in dispute here. The project is before the Public Utilities Board for a Major New Facilities Review, which tests the need, the alternatives and the rate impact before the Board advises cabinet.
What is contested
Three things, and none of them is whether Manitoba needs the capacity.
Cold-weather performance
Under questioning at the Board, Manitoba Hydro agreed that it had derated the existing Brandon turbines during three of the top ten multi-day winter peak events of the past decade. Capacity insurance is judged on whether it pays out when claimed, and that record is the reason the alternatives deserve the same scrutiny the gas plan receives.
Cost per planning-case kilowatt
At nameplate, $3 billion for 750 MW is about $4,000 per kilowatt. A portfolio of recovered heat, batteries, residual demand response and interties is $1.95B / 688 MW = $2,834 per planning-case kW gross, and $2,180 net if the federal Clean Technology investment tax credit is confirmed. Those denominators are not the same: one is a planning stack, the other is nameplate.
What is left out
Hydro's recommended plan already pairs the turbines with roughly 600 MW of wind, 550 MW of efficiency and 310 MW of demand response. What it does not include is recovered heat from Winnipeg's North End plant — which is being rebuilt right now, the one moment those heat taps are cheap to install.
This filing does not ask the Board to reject the project. It asks for the two plans to be tested the same way before any capital certificate is granted: head-to-head modelling, an independent cold-weather reliability audit using identical accreditation rules for both, and machine-readable cost models from both parties.
Check any of this
Every figure above is in a public registry with its evidence class and source, pinned by automated tests you can run yourself. If a number is wrong, the forum is where to say so.
Where to go next
The rest of this filing, in the order a stranger tends to need it: what is being proposed, whether it has already been decided, whether the case for it holds, and how to be heard before 4 September 2026.
