New Brunswick’s energy transition has moved from an abstract discussion to a very concrete decision at the Belledune Generating Station. The Belledune coal conversion is now moving from planning into execution, and the public-interest test is whether it can preserve reliable electricity while delivering credible emissions reductions, sustainable fuel sourcing and reasonable long-term costs.
On September 17, NB Power announced that its plan to convert Belledune from coal to sustainably sourced advanced pellets had moved from planning into execution. The utility’s board approved the project in August, and NB Power has now signed agreements with Canadian suppliers covering the majority of the fuel it expects to need.
That matters because Belledune is not a small or peripheral part of the provincial electricity system. The Belledune Generating Station has a capacity of 467 megawatts and NB Power describes it as an important source of dependable and predictable electricity, particularly when demand is high. At the same time, it is currently the most greenhouse-gas-intensive generating station in NB Power’s fleet.
Those two facts explain both the attraction and the difficulty of the project. New Brunswick needs to move away from coal, but it also needs reliable electricity. Keeping an existing 467-MW station available while changing its fuel could offer a practical bridge between those goals. But calling the new fuel renewable cannot be the end of the public-interest test.
The Belledune coal conversion is moving beyond the experimental stage
The idea of operating Belledune on advanced pellets has already gone through several years of testing. NB Power began introducing advanced wood pellets to the boiler in March 2024 and says the station successfully operated twice on 100 per cent advanced pellets. A second round of testing followed in November 2024 to help refine the estimated cost of a full conversion.
The current project schedule shows that the fuel-supply strategy was finalized in May 2026 and the final investment decision was completed in August. NB Power is targeting September 2027 for a construction permit, with another test burn planned during 2026–27. Full biomass conversion is currently expected sometime between 2028 and 2030, although the exact timing remains to be determined.
The September announcement is therefore more significant than another feasibility study. NB Power says Canadian supply agreements now cover the majority of the fuel requirement. The utility describes the planned fuel as advanced pellets made from wood and agricultural hemp biomass.
That gives New Brunswick something concrete to evaluate: not whether biomass might theoretically work at Belledune, but whether this particular conversion can provide dependable electricity at an acceptable environmental and financial cost.
Reliability is a legitimate public concern
It would be easy to frame the debate as coal versus renewable energy and stop there. Electricity systems are more complicated.
New Brunswick has winter peaks, industrial demand and periods when variable generation cannot supply everything the province needs. A generating station that can be called upon predictably has real value. Retaining useful existing infrastructure may also avoid some of the cost and disruption involved in replacing hundreds of megawatts of dependable capacity all at once.
That does not mean the reliability argument should simply be accepted without evidence. NB Power should clearly report how Belledune is expected to operate after conversion: its dependable capacity, anticipated annual generation, fuel requirements, operating costs and expected role alongside Point Lepreau, hydroelectric generation, wind, imports and future generation projects.
If keeping Belledune substantially reduces the amount of new firm capacity New Brunswick would otherwise need to build or purchase, residents should be able to see that value in the numbers. This is the same broader public-interest question I raised when looking at how major Canadian infrastructure investment should be measured: public support and major capital decisions should produce transparent, durable public value.
Renewable does not automatically mean impact-free
The most important environmental question is not whether advanced pellets can legally or technically be described as renewable. It is what their full lifecycle impact will be.
Biomass emissions depend on where the feedstock comes from, what would otherwise have happened to that material, how it is harvested, processed and dried, how far it travels, what energy is used in pellet production and transportation, and how forests or agricultural sources are managed over time.
The provincial government says Belledune’s fuel will come through established Canadian forestry and wood-processing supply chains and will have to meet recognized sustainability standards and applicable regulatory requirements. NB Power also says the advanced pellets will come from sustainable existing sources rather than requiring new large-scale forestry operations.
Those are important commitments, but they should become measurable public requirements rather than reassuring phrases.
Lifecycle accounting matters because the environmental impact of a fuel extends beyond what happens at the point of combustion. Public reporting on Belledune should account for sourcing, processing, transportation and land-use assumptions, not simply compare the labels “coal” and “renewable.”
NB Power should publish the sustainability standards used for every major supply contract and report the estimated lifecycle greenhouse-gas intensity of the fuel. Residents should be able to compare the converted station not only with coal, but with realistic alternatives for supplying the same dependable electricity.
The $65-million price tag is only the beginning of the cost discussion
The provincial government estimates the conversion itself will cost about $65 million. For a project retaining hundreds of megawatts of existing generation, that headline capital cost deserves attention.
But ratepayers ultimately pay for more than conversion equipment.
The complete financial picture includes pellet prices, transportation, storage and handling, plant maintenance, equipment life, future upgrades, financing, regulatory costs and the terms of long-term fuel contracts. It should also identify any provincial or federal subsidies and explain who carries the risk if fuel prices or supply conditions change.
A relatively modest conversion cost could be an excellent investment if it preserves dependable capacity, reduces emissions and produces competitive long-term electricity costs. The opposite is also possible if the initial capital figure obscures expensive fuel commitments or future operating risks.
The public does not need commercially sensitive details that would genuinely harm suppliers. It does need enough information to understand the long-term cost per unit of electricity and how that compares with credible alternatives.
Northern New Brunswick should see more than a fuel change
The economic case for Belledune is potentially significant.
The province estimates the conversion could support 713 full-time-equivalent jobs annually across the Canadian supply chain and generate approximately $85 million in annual GDP activity by replacing imported coal with Canadian-produced pellets. The industries potentially involved include forestry, agriculture, trucking, rail and shipping.
Those are substantial claims. They should become the starting point for future accountability rather than numbers that disappear after the announcement.
Government and NB Power should report how many jobs actually materialize, where they are located, how much procurement stays in New Brunswick, how much activity occurs in the north, and whether the project creates durable employment rather than only temporary construction activity.
Indigenous participation should be visible and meaningful
One of the fuel-supply developments also gives the project an important Indigenous economic dimension.
A Belledune joint venture involving Pabineau First Nation, Eel River Bar First Nation, Arbec Forest Products and Airex Energy has announced a long-term biomass supply agreement with NB Power. The proposed facility at the Port of Belledune would transform sustainably sourced forestry residues into torrefied pellets for the generating station.
That is more meaningful than treating Indigenous communities solely as groups to be consulted after the major economic decisions have already been made. Participation in ownership, supply chains and long-term economic activity can create a different relationship to major infrastructure projects.
At the same time, economic participation does not replace the Crown’s obligations toward Indigenous rights-holders. NB Power says engagement with First Nations and stakeholders will continue throughout the project. That process should remain transparent and substantive as permitting, construction and long-term operation proceed.
Fuel security matters too
Belledune currently burns imported coal. Moving to Canadian-produced fuel potentially changes more than the station’s emissions profile.
A domestic supply chain can keep more spending within Canada and reduce exposure to some international fuel risks. But a new supply chain brings its own dependencies. Long-term reliability requires enough pellet-production capacity, transportation infrastructure, storage and competing supply options to keep a 467-MW generating station fuelled when it is needed most.
That makes the recently signed supply agreements important. It also means NB Power should eventually explain how diversified the supply chain is and what contingency plans exist if one producer or transportation route cannot deliver.
Energy security should mean more than replacing one dependence with another.
Five measures should define whether the project succeeds
Belledune’s conversion should be judged against a public scorecard rather than by whether the project is completed on schedule.
First, reliability. Does the converted station provide the dependable capacity and electricity NB Power says the province needs?
Second, affordability. What is the full long-term cost of generation after fuel, transportation, maintenance and capital expenses are included, and what does that mean for ratepayers?
Third, lifecycle emissions. How much greenhouse-gas reduction is actually achieved compared with coal, using transparent assumptions that account for sourcing, processing and transportation?
Fourth, sustainable sourcing. Are the pellets consistently produced from sources that meet clearly identified environmental standards without creating new pressure for unsustainable harvesting?
Fifth, regional and Indigenous benefits. Do the promised jobs, investment, contracts and economic opportunities actually reach northern New Brunswick and participating First Nations?
A practical transition still requires public proof
There is a reasonable case for converting Belledune rather than simply closing it in 2030. New Brunswick would retain a large source of dependable generation, move away from imported coal, build Canadian fuel supply chains and potentially preserve economic activity around an important northern New Brunswick industrial asset.
There are equally reasonable questions about biomass emissions, long-term fuel costs, forestry impacts and whether projected economic benefits will materialize.
Those questions do not make the project a bad idea. They make transparency essential.
New Brunswick’s energy transition will involve trade-offs. Residents should not be asked to choose between slogans about renewable energy and warnings about reliability. They should be given enough information to judge the actual results.
If Belledune can provide dependable electricity beyond 2030 at a competitive cost, while demonstrating credible lifecycle emissions reductions, sustainable fuel sourcing and durable benefits for northern and Indigenous communities, the conversion could become a practical piece of New Brunswick’s transition away from coal.
The standard should be straightforward: measure those promises, publish the results and let New Brunswickers see whether the project delivers.
