Sustainable Marine tidal energy delivers in-stream power to Nova Scotia's grid from Grand Passage, proving low-impact, renewable generation and advancing a floating tidal array at FORCE and Minas Passage in the Bay of Fundy.

 

Key Points

The first in-stream tidal project supplying clean power to Nova Scotia's grid, proven at Grand Passage.

✅ First to deliver in-stream tidal power to Canada's grid

✅ Demonstration at Grand Passage informs FORCE deployments

✅ Low-impact design and environmental monitoring validated

 

Sustainable Marine has officially powered up its tidal energy operation in Canada and is delivering clean electricity to the power system in Nova Scotia, on the country’s Atlantic coast, as the province moves to increase wind and solar projects in the years ahead. The company’s system in Grand Passage is the first to deliver in-stream tidal power to the grid in Canada, following provincial approval to harness Bay of Fundy tides that is spurring further development.

The system start-up is the culmination of more than a decade of research, development and testing, including lessons from Scottish tidal projects in recent years and a powerful tidal turbine feeding onshore grids, managing the technical challenges associated with operating in highly energetic environments and proving the ultra-low environmental impact of the tidal technology.

Sustainable Marine is striving to deliver the world’s first floating tidal array at FORCE (Fundy Ocean Research Centre for Energy). This project will be delivered in phases, drawing upon the knowledge gained and lessons learned in Grand Passage, and insights from offshore wind pilots like France’s first offshore wind turbine in Europe. In the coming months the company will continue to operate the platform at its demonstration site at Grand Passage, gradually building up power production, while New York and New England clean energy demand continues to rise, to further prove the technology and environmental monitoring systems, before commencing deployments in the Minas Passage – renowned as the Everest of tidal energy.

The Bay of Fundy’s huge tidal energy resource contains more than four times the combined flow of every freshwater river in the world, with the potential to generate approximately 2,500 MW of green energy, underscoring why independent electricity planning will be important for integrating marine renewables.

Warren Buffett-linked company to build $200M wind power farm in Alberta

Rattlesnake Ridge Wind Project delivers 117.6 MW in southeast Alberta for BHE Canada, a Berkshire Hathaway Energy subsidiary, using 28 turbines near Medicine Hat under a long-term PPA, supplying renewable power to 79,000 homes.

 

Key Points

A 117.6 MW Alberta wind farm by BHE Canada supplying 79,000 homes via 28 turbines and a long-term PPA.

✅ 28 turbines near Medicine Hat, 117.6 MW capacity

✅ Long-term PPA with a major Canadian corporate buyer

✅ Developed with RES; no subsidies; competitive pricing

 

A company linked to U.S. investor Warren Buffett says it will break ground on a $200-million, 117.6-megawatt wind farm in southeastern Alberta next year.

In a release, Calgary-based BHE Canada, a subsidiary of Buffett's Berkshire Hathaway Energy, says its Rattlesnake Ridge Wind project will be located southwest of Medicine Hat and will produce enough energy to supply the equivalent of 79,000 homes.

"We felt that it was time to make an investment here in Alberta," said Bill Christensen, vice-president of corporate development for BHE Canada, in an interview with the Calgary Eyeopener.

"The structure of the markets here in Alberta, including frameworks for selling renewable energy, make it so that we can invest, and do it at a profit that works for us, and at a price that works for the off-taker," Christensen explained.

Berkshire Hathaway Energy also owns AltaLink, the regulated transmission company that supplies electricity to more than 85 per cent of the Alberta population.

BHE Canada says an unnamed large Canadian corporate partner has signed a long-term power purchase agreement, similar to RBC's solar purchase arrangements, for the majority of the energy output generated by the 28 turbines at Rattlesnake Ridge.

"If you look at just the raw power price that power is going for in Alberta right now, it's averaged around $55 a megawatt hour, or 5.5 cents a kilowatt hour. And we're selling the wind power to this customer at substantially less than that, reflecting wind power's competitiveness in the market, and there's been no subsidies," Christensen said.

 

Positive energy outlook

Christensen said he sees a good future for Alberta's renewable energy industry, not just in wind but also in solar power growth, particularly in the southeast of the province.

But he says BHE Canada is interested in making investments in traditional energy in Alberta, too, as the province is a powerhouse for both green energy and fossil fuels overall.

"It's not a choice of one or the other. I think there is still opportunity to make investments in oil and gas," he said.

"We're really excited about having this project and hope to be able to make other investments here in Alberta to help support the economy here, amid a broader renewable energy surge across the province."

The project is being developed by U.K.-based Renewable Energy Systems, part of a trend where more energy sources make better projects for developers, which is building two other Alberta wind projects totalling 134.6 MW this year and has 750 MW of renewable energy installed or currently under construction in Canada.

BHE Canada and RES are also looking for power purchase partners for the proposed Forty Mile Wind Farm in southeastern Alberta. They say that with generation capacity of 398.5 MW, it could end up being the largest wind power project in Canada.

OEB issues decision on Hydro One's first combined T&D rates application

OEB Hydro One Rate Decision 2023-2027 sets approved transmission and distribution rates in Ontario, with a settlement reducing revenue requirement, modest bill impacts, higher productivity factors, inflation certainty, DVA credits, and First Nations participation measures.

 

Key Points

OEB-approved Hydro One 2023-2027 transmission and distribution rates settlement, lowering costs and limiting bill impacts.

✅ $482.7M revenue reductions vs. original proposal

✅ Avg bill impact: +$0.69 trans., +$2.43 distr. per month

✅ Faster DVA refunds; productivity and efficiency incentives

 

The Ontario Energy Board (OEB) issued its Decision and Order on an application filed by Hydro One Networks Inc. (Hydro One) on August 5, 2021 seeking approval for changes to the rates it charges for electricity transmission and distribution, beginning January 1, 2023 and for each subsequent year through to December 31, 2027. 

The proceeding resulted in the filing of a settlement proposal that the OEB has now approved after concluding that it is in the public interest. 

The negotiated reductions in Hydro One's transmission and distribution revenue requirements over the 2023 to 2027 period total $482.7 million compared to the requests made by Hydro One in its application.

The OEB found that the reductions in Hydro One's proposed capital expenditure and operating, maintenance and administration costs were reasonable, and should not compromise the safety and reliability of Hydro One's transmission and distribution systems. It also concluded that the estimated bill impacts for both transmission and distribution customers are reasonable, and that the January 1, 2023 implementation and effective date of the new rates is appropriate.

In the broader Canadian context, pressures on utility finances at other companies, such as Manitoba Hydro's debt provide additional background for stakeholders.

 

Bill Impacts

This proceeding related to both transmission and distribution operations.

 

Transmission

The new transmission revenue requirement will affect Ontario electricity consumers across the province because it will be incorporated into updated transmission rates, which are paid by electricity distributors and other large consumers connected directly to the transmission system, and distributors then pass this cost on to their customers.

As a result of the settlement approved on the transmission portion of the application, it is estimated that for a typical Hydro One residential customer with a monthly consumption of 750 kWh, the total bill impact averaged over the 2023-2027 period will be an increase of $0.69 per month or 0.5%, which follows the 2021 electricity rate reductions that affected many businesses.

 

Distribution

The new OEB-approved distribution rates will affect Hydro One's distribution customers, including areas served through acquisitions such as the Peterborough Distribution sale which expanded its customer base.

As a result of the settlement reached on the distribution portion of the application, it is estimated that for a typical residential distribution customer of Hydro One with a monthly consumption of 750 kWh, the total bill impact averaged over the 2023-2027 period will be an increase of $2.43 per month or 1.5%.
This proceeding included 24 approved intervenors representing a wide variety of customer classes and other interests. Representatives of 18 of those intervenors participated in the settlement conference. Having this diversity of perspective enriches the already thorough examination of evidence and argument that the OEB routinely undertakes when considering an application.

Other features of the settlement proposal include:

  • A commitment by Hydro One to include, in future operational and capital investment plans, a discussion of how the proposed spending will directly support the achievement of Hydro One's climate change policy.
  • Eliminating further updates to reflect changes to inflation in 2022 and 2023 as originally proposed, to provide Hydro One's customers with greater certainty as to the potential impacts of inflation on their bills.
  • Increases in the productivity factors and supplemental stretch factors for both the distribution and transmission business segments which will provide Hydro One with additional incentives to achieve greater efficiencies during the 2023 to 2027 period.
  • Undertaking certain measures to seek economic participation or equity investment opportunities from First Nations.
  • Disposition of net credit balances in deferral and variance accounts (DVAs) owed to customers will be returned over a shorter period of time:
  • Transmission DVA – $22.5M over a one-year period in 2023 (versus five years)
  • Distribution DVA – $85.9M over a three-year period – 2023-2025 (versus five years)
  • Undertaking certain measures to continue examining cost-effective transmission and distribution line losses
  • In the decision, the OEB acknowledged the efforts involved by parties to participate in this entire proceeding, including the settlement conference, considering the number of participants, the complexity of the issues, and the challenging logistics of a "virtual" proceeding. The OEB commended the parties and OEB staff for achieving a comprehensive settlement on all issues.

NB Power signs three deals to bring more Quebec electricity into the province

NB Power and Hydro-Québec Electricity Agreements expand clean hydroelectric exports, support Mactaquac dam refurbishment, add grid interconnections, and advance decarbonization, climate goals, reliability, and transmission capacity across Atlantic Canada and U.S. markets through 2040.

 

Key Points

Deals for hydro exports, Mactaquac upgrades, and new interconnections to improve reliability and cut emissions.

✅ 47 TWh to NB by 2040 over existing transmission lines

✅ HQ expertise to address Mactaquac concrete swelling

✅ Talks on new interconnections for Atlantic and U.S. exports

 

NB Power and Hydro-Quebec have signed three deals that will see Quebec sell more electricity to New Brunswick and provide help with the refurbishment of the Mactaquac hydroelectric generating station.

Under the first agreement, Hydro-Quebec will export 47 terawatt hours of electricity to New Brunswick between now and 2040 over existing power lines — expanding on an agreement in place since 2012 and on related regional agreements such as the Churchill Falls deal in Newfoundland and Labrador.

The second deal will see Hydro-Quebec share expertise for part of the refurbishment of the Mactaquac dam to extend the useful life of the generating station until at least 2068, when the 670 megawatt facility on the St. John River will be 100 years old.

Since the 1980s, concrete portions of the facility have been affected by a chemical reaction that causes the concrete to swell and crack.

Hydro-Quebec has been dealing with the same problem, and has developed expertise in addressing the issue.

“This is why we have signed a technical collaboration agreement between Hydro-Quebec and us for part of the refurbishment of the Mactaquac generating station,” NB Power president Gaetan Thomas said Friday.

Eric Martel, CEO of Hydro-Quebec, said hydroelectric plants provide long-term clean power that’s important in the fight against climate change as the province has ruled out nuclear power for now.

“We understand how important it is to ensure the long term sustainability of these facilities and we are happy to share the expertise that Hydro-Quebec has acquired over the years,” Martel said.

The refurbishment of the Mactaquac generating station is expected to cost between $2.9 billion and $3.5 billion. Once the work begins, each of the facility’s six generators will have to be taken offline for months at a time, and Thomas said that’s where the increased power from Quebec, supported by Hydro-Quebec's capacity expansion in recent years, will come into use.

He expects the power could cost about $100 million per year but will be much cheaper than other sources.

The third agreement calls for talks to begin for the construction of additional power connections between Quebec and New Brunswick to increase exports to Atlantic Canada and the United States, where transmission constraints have limited incremental deliveries in recent years.

“Building new interconnections and allowing for increased power transfer between our systems could be mutually beneficial, even as historic tensions in Newfoundland and Labrador linger. More than ever, we are looking to the future,” Martel said.

“Partnering will permit us to seize new business opportunities together and pool our effort to support de-carbonization, including Hydro-Quebec's non-fossil strategy that is now underway, and fight against climate change, both here and in our neighbourhood market,” he said.

Irving Oil invests in electrolyzer to produce hydrogen from water

Irving Oil hydrogen electrolyzer expands green hydrogen capacity at the Saint John refinery with Plug Power technology, cutting carbon emissions, enabling clean fuel for buses, and supporting Atlantic Canada decarbonization and renewable grid integration.

 

Key Points

A 5 MW Plug Power unit at Irving's Saint John refinery producing low-carbon hydrogen via electrolysis.

✅ Produces 2 tonnes/day, enough to fuel about 60 hydrogen buses

✅ Uses grid power; targets cleaner supply via renewables and nuclear

✅ First Canadian refinery investing in electrolyzer technology

 

Irving Oil is expanding hydrogen capacity at its Saint John, N.B., refinery in a bid to lower carbon emissions and offer clean energy to customers.

The family-owned company said Tuesday it has a deal with New York-based Plug Power Inc. to buy a five-megawatt hydrogen electrolyzer that will produce two tonnes of hydrogen a day — equivalent to fuelling 60 buses with hydrogen — using electricity from the local grid and drawing on examples such as reduced electricity rates proposed in Ontario to grow the hydrogen economy.

Hydrogen is an important part of the refining process as it's used to lower the sulphur content of petroleum products like diesel fuel, but most refineries produce hydrogen using natural gas, which creates carbon dioxide emissions and raises questions explored in hydrogen's future for power companies in the energy sector.

"Investing in a hydrogen electrolyzer allows us to produce hydrogen in a very different way," Irving director of energy transition Andy Carson said in an interview.

"Instead of using natural gas, we're actually using water molecules and electricity through the electrolysis process to produce ... a clean hydrogen."

Irving plans to continue to work with others in the province to decarbonize the grid amid pressures like Ontario's push into energy storage as electricity supply tightens and ensure the electricity being used to power its hydrogen electrolyzer is as clean as possible, he said.

N.B. Power's electrical system includes 14 generating stations powered by hydro, coal, oil, wind, nuclear and diesel. The utility has committed to increasing its renewable energy sources and exploring innovations such as EV-to-grid integration piloted in Nova Scotia.

Irving said it will be the first oil refinery in Canada to invest in electrolyzer technology, as Ontario's Hydrogen Innovation Fund supports broader deployment nationwide.

The company said its goal is to offer hydrogen fuelling infrastructure in Atlantic Canada, complementing N.L.'s fast-charging network for EV drivers in the region.

"This kind of investment allows us to not just move to a cleaner form of hydrogen in the refinery. It also allows us to store and make hydrogen available to the marketplace," Carson said.

Federal watchdog warns Canada's 2030 emissions target may not be achievable
The hydrogen technology will help Irving "unlock pent up demand for hydrogen as an energy transition fuel for logistics organizations," he said.

Alberta also aims to expand its hydrogen production over the coming years, alongside British Columbia's $900 million hydrogen project moving ahead on the West Coast. 

Those plans lean on the development of carbon capture and storage (CCS) technology that aims to trap the emissions created when producing hydrogen from natural gas.

TransAlta Scraps Wind Farm as Alberta's Energy Future Blusters

Alberta Wind Energy Policy Changes highlight TransAlta's Riplinger cancellation amid UCP buffer zones for pristine viewscapes, regulatory uncertainty, and market redesign debates, reshaping Alberta's renewables investment climate and clean energy diversification plans.

 

Key Points

UCP rules and market shifts reshaping wind siting, permits, and finance, increasing uncertainty and delays for new projects.

✅ 35-km buffer near pristine viewscapes limits wind siting

✅ TransAlta cancels 300 MW Riplinger project

✅ Market redesign uncertainty chills renewables investment

 

The winds of change are blowing through Alberta's energy landscape today, and they're not necessarily carrying good news for renewable energy development. TransAlta, a major Canadian energy company, recently announced the cancellation of a significant wind farm project, citing a confluence of factors that create uncertainty for the future of wind power in the province. This decision throws a spotlight on the ongoing debate between responsible development and fostering a clean energy future in Alberta.

The scrapped project, the Riplinger wind farm near Cardston, Alberta, was envisioned as a 300-megawatt facility capable of providing clean electricity to the province. However, TransAlta pointed to recent regulatory changes implemented by the United Conservative Party (UCP) government, following the end of the renewable energy moratorium in Alberta, as a key reason for the project's demise. These changes include the establishment of a 35-kilometer buffer zone around designated "pristine viewscapes," which significantly restricts potential wind farm locations.

John Kousinioris, CEO of TransAlta, expressed frustration with the lack of clarity surrounding the future of renewable energy policy in Alberta. He highlighted this, along with the aforementioned rule changes, as major factors in the project's cancellation. TransAlta has also placed three other power projects on hold, indicating a broader concern about the current investment climate for renewable energy in the province.

The news has been met with mixed reactions. While some residents living near the proposed wind farm site celebrate the decision due to concerns about potential impacts on tourism and the environment, others worry about the implications for Alberta's clean energy ambitions, including renewable energy job growth in the province. The province, a major energy producer in Canada, has traditionally relied heavily on fossil fuels, and this decision might be seen as a setback for its goals of diversifying its energy mix.

The Alberta government defends its changes to renewable energy policy, arguing that they are necessary to ensure responsible development and protect sensitive ecological areas. However, the TransAlta decision raises questions about the potential unintended consequences of these changes. Critics argue that the restrictions might discourage investment in renewable energy and the province's ability to sell clean power to wider markets altogether, hindering Alberta's progress towards a more sustainable future.

Adding to the uncertainty is the ongoing process of redesigning Alberta's energy market. The aim is to incorporate more renewable energy sources, including solar energy expansion across the grid, but the details of this redesign remain unclear. This lack of transparency makes it difficult for companies like TransAlta to make sound investment decisions, further dampening enthusiasm for renewable energy projects.

The future of wind energy development in Alberta remains to be seen. TransAlta's decision to scrap the Riplinger project is a significant development, and it will be interesting to observe how other companies respond to the changing regulatory landscape, as a Warren Buffett-linked developer pursues a $200 million wind project in Alberta. Striking a balance between responsible development, protecting the environment, and fostering a clean energy future will be a crucial challenge for Alberta moving forward.

This situation highlights the complex considerations involved in transitioning to a renewable energy future, where court rulings on wind projects can influence policy and investment decisions. While environmental concerns are paramount, ensuring a stable and predictable investment climate is equally important. Open communication and collaboration between industry, government, and stakeholders will be key to navigating these challenges and ensuring Alberta can harness the power of wind energy for a sustainable future.
