Nova Scotia’s coal plants are shutting down. As the province shifts to wind and solar, it needs backup power that can ramp up fast when the wind dies or demand spikes on a cold January night. It also needs something to keep the grid physically stable as the heavy spinning turbines in coal plants go offline. These are real needs.
IESO Nova Scotia’s answer is two 300 MW natural gas plants in Pictou County, locked in for 25 years.
Community members and ratepayers deserve to know what that actually means and whether cleaner, cheaper options exist.
IESO Nova Scotia plans to build two fossil fuel plants in Pictou County — one at Marshdale, one at Salt Springs, 20 km apart. Nova Scotia ratepayers will pay for them through their electricity bills for the next 20 to 27 years. The operator’s profit is guaranteed whether the plants run or not. All fuel costs, all carbon costs, and all interconnection overruns are passed to ratepayers. The pricing is confidential and may never be published.
Each plant would extract up to 175,000 litres of groundwater per hour from rural wells, emit 325,594 tonnes of CO² per year, store 9 million litres of diesel fuel on site, and discharge treated wastewater into local watercourses. The proponent’s own modelling shows that 18–42% of pumping at Marshdale could come from depleting Cameron Brook. Per unit of electricity generated, these plants emit over 8× the federal emissions standard and can only operate because of a planned unit exemption in Canada’s Clean Electricity Regulations.
Both projects were approved by the Minister of Environment in a single sentence, after 129 public submissions — every one opposed. The approval conditions contain no limits on water extraction, air emissions, noise, or hours of operation. Those will be determined later, in processes that have not yet begun.
The proposed technology uses water injection for emissions control, requiring 14–19 production wells at Marshdale. The EARD's own modelling shows 18–42% of pumping could come from depleting Cameron Brook. Alternative technologies exist that use near-zero water.
Read about the water →Under the Tolling Agreement, the plant operator receives a fixed capacity payment every month whether or not the plant generates any electricity. All fuel costs are passed through to ratepayers at 100%. If gas prices spike, ratepayers cover the increase.
Read about the risk →These plants emit over 8× more CO2 per GWh than the federal standard. They can only operate because of a "planned unit" loophole in Canada's Clean Electricity Regulations - an exemption that required a rushed timeline to qualify.
Read about the exemption →Grid-forming battery storage can provide the same synchronous condenser services these plants offer. NRStor's proposed 150 MW Trenton BESS project in Nova Scotia is shovel-ready, 50% Mi'kmaw owned, and designed for exactly this purpose.
Read about BESS →KMK, the Mi’kmaw consultation body, stated that the province declined to meet its consultation obligations under the Constitution Act. The project has significant potential to impact salmon, moose, and black ash — species tied to established Mi’kmaq fishing, hunting, and harvesting rights. The EARD was released without a completed Mi’kmaq Ecological Knowledge Study.
Read the KMK submission →Nova Scotia has zero gas production and zero storage. These plants depend on a pipeline through New England — where gas is scarcest in winter cold snaps, exactly when peakers are needed. Two plants consuming 155% of current provincial gas demand create a government-guaranteed market that makes the case for domestic fracking.
Read about the supply chain →Both projects went through a public comment period over the holidays (December 22, 2025 – February 9, 2026). Despite the short window and the timing, Nova Scotians showed up. The response was overwhelming — and universally opposed.
Submissions came from residents living near the sites, Nova Scotians across the province, and six organizations: the Sierra Club Canada Foundation, the Ecology Action Centre, the Canadian Association of Physicians for the Environment, the Margaree Environmental Association, Pictou Landing First Nation, and Kwilmu’kw Maw-Klusuaqn (KMK).
“Contrary to the statement in your previous letter that ‘the nature of this project is not likely to lead to appreciable adverse impacts to credibly asserted or established Mi’kmaq Aboriginal or Treaty rights,’ it is the understanding of the KMK that this project has significant potential to impact salmon, moose and black ash, at a minimum. Accordingly, it has the potential to cause appreciable adverse impacts to the Mi’kmaq’s established and asserted fishing, hunting and harvesting rights.” — Kwilmu’kw Maw-Klusuaqn (KMK), Director of Consultation
“With Pictou Landing being the nearest Mi’kmaw Community and having a dark history of large-scale industrial developments adjacent to their community, such as the Boat Harbor Project, it is imperative that the local Mi’kmaw Communities are adequately informed well in advance of large-scale projects such as this.” — Kwilmu’kw Maw-Klusuaqn (KMK)
“Across multiple issue areas, the assessment exhibits a consistent and material pattern: potential adverse effects are systematically understated, not because evidence demonstrates they are insignificant, but because key analytical steps are deferred, scoped narrowly, or based on assumptions that are neither defined nor tested within the EA record itself.” — Sierra Club Canada Foundation
“We have been here for 40+ years, raised a family and have never had an issue with our well, even with this past year of extreme drought. … Should private wells go dry it appears that homeowners will be tasked to prove this project is the root of the problem.” — Anonymous couple, Salt Springs
“If provincial approval processes can override municipal zoning restrictions to permit major industrial facilities in residential areas, then no rural community in Nova Scotia possesses meaningful protection against similar impositions.” — Anonymous commenter, within 1 km of Salt Springs site
The Minister’s response to all of this:
“I am satisfied that any adverse effects or significant environmental effects of the undertaking can be adequately mitigated through compliance with the attached terms and conditions.” — Minister Timothy Halman, February 19, 2026 — identical single-sentence decision for both projects
The conditions contain no limits on water, air, noise, or operations — they require IESO to submit plans to do that work after the approval.
Nova Scotia faces real grid challenges as coal retires. The province needs fast-acting capacity and grid stability services. The question is not whether something needs to be built — it’s whether these peaker plants are the best answer... and it looks like they might not be.
The case for the gas plants rests on NS Power’s 2022/2023 Evergreen Integrated Resource Plan, which used a PLEXOS model run by consulting firm E3. That model has a structural assumption that determines its conclusion: battery storage was modelled exclusively as 4-hour energy storage. Grid-forming BESS — the technology that can replace synchronous condensers for grid stability — was not an available resource type in the model. The optimizer was structurally forced to select gas turbines or synchronous condensers for inertia, not because batteries lost a fair comparison, but because the alternative didn’t exist as an input at the time.
The strongest evidence that grid-forming BESS can replace gas-plus-synchronous-condenser combinations was published after the IRP modelling was complete. The IESO is now procuring gas based on a model that didn’t — and couldn’t — consider the alternative.
When NS Power finalized its Evergreen IRP in August 2023, grid-forming BESS at transmission scale hadn’t been demonstrated delivering full stability services. If NS Power had moved straight to procurement, gas plant contracts could have been signed before the cleaner alternative existed in any operational form anywhere in the world.
That procurement didn’t happen. In April 2024, Nova Scotia passed Bill 404 and transferred procurement responsibility from NS Power to a brand-new Independent Energy System Operator. The IESO, as a new organization, took some time to get up to speed. The first gas peaker procurement call for interest didn’t go out until October 2025 — more than two years after the IRP recommended the gas plants.
In that two-year gap, grid-forming BESS went from “promising lab demonstration” to “operational at transmission scale.” Blackhillock went live in March 2025. The ESIG/GridLab study confirming GFM BESS meets grid-forming specifications was published the same month. Kilmarnock South followed in January 2026. By the time the IESO’s draft gas RFP landed in March 2026, the cleaner, cheaper alternative that wasn't part of the IRP model had become a proven, deployed technology.
NS Power had an opportunity to incorporate the new evidence. One month after Blackhillock went operational, NS Power published its April 2025 IRP Action Plan Update — and continued to recommend gas combustion turbines, citing the same 2023 modelling unchanged. Six months later, the IESO issued the gas RFEoI on that basis.
The original gas procurement delay accidentally created the Leapfrog Opportunity. Nova Scotia can now skip past legacy gas peaker technology entirely and go directly to grid-forming BESS — the same way some countries skipped landlines and went straight to mobile phones. The technology matured during the delay and the case for going back to gas no longer exists.
Grid-forming battery storage provides the same inertia, frequency response, and voltage regulation as the synchronous condensers these plants would operate as 70%+ of the time — without burning fuel, extracting water, or emitting CO². A 2025 ESIG/GridLab study confirmed all tested GFM BESS passed NERC grid-forming specifications.
Read the evidence →Europe’s largest BESS went operational in March 2025 at Blackhillock, Scotland, providing grid stability for offshore wind integration and replacing services previously provided by fossil fuel plants. A second 300 MW installation at Kilmarnock South followed in January 2026 — exactly the scale of each proposed NS gas plant.
Read the case study →A 150 MW / 600 MWh battery project proposed for Trenton, Pictou County — on industrially-zoned land with an existing grid connection. 50% Mi’kmaw owned through all 13 Nova Scotia First Nations. Zero water, zero emissions, zero fuel cost risk. Built by the team behind Canada’s largest BESS (Oneida, 250 MW, operational May 2025).
Read about NRStor →The RFP is still in draft. Your voice matters now — before contracts are signed and ratepayers are locked in for 25 years.
