Located in the remote Diavik Diamond Mine, approximately 220 kilometers south of the Arctic Circle, Rio Tinto's off-grid solar power plant represents a technological feat in harnessing renewable energy in challenging environments. The plant is designed to reduce reliance on diesel fuel, traditionally used to power the mine's operations, and mitigate carbon emissions associated with mining activities.

The decision to build the solar power plant aligns with Rio Tinto's broader sustainability goals and commitment to reducing its environmental footprint. By integrating renewable energy sources like solar power, a strategy that renewable developers say leads to better, more resilient projects, the company aims to enhance energy efficiency, lower operational costs, and contribute to global efforts to combat climate change.

The Diavik Diamond Mine, jointly owned by Rio Tinto and Dominion Diamond Mines, operates in a remote region where access to traditional energy infrastructure is limited, and where, despite lagging solar demand in Canada, off-grid solutions are increasingly vital for reliability. Historically, diesel generators have been the primary source of power for the mine's operations, posing logistical challenges and environmental impacts due to fuel transportation and combustion.

Rio Tinto's investment in the off-grid solar power plant addresses these challenges by leveraging abundant sunlight in the Northwest Territories to generate clean electricity directly at the mine site. The solar array, equipped with advanced photovoltaic technology, which mirrors deployments such as Arvato's first solar plant in other sectors, is capable of producing a significant portion of the mine's electricity needs during peak solar hours, reducing reliance on diesel generators and lowering overall carbon emissions.

Moreover, the completion of the largest off-grid solar power plant in Canada's Northwest Territories underscores the feasibility and scalability of renewable energy solutions, from rooftop arrays like Edmonton's largest rooftop solar to off-grid systems in remote and resource-intensive industries like mining. The success of this project serves as a model for other mining companies seeking to enhance sustainability practices and operational resilience in challenging geographical locations.

Beyond environmental benefits, Rio Tinto's initiative is expected to have positive economic and social impacts on the local community. By reducing diesel consumption, the company mitigates air pollution and noise levels associated with mining operations, improving environmental quality and contributing to the well-being of nearby residents and wildlife.

Looking ahead, Rio Tinto's investment in renewable energy at the Diavik Diamond Mine sets a precedent for responsible resource development and sustainable mining practices in Canada, where solar growth in Alberta is accelerating, and globally. As the mining industry continues to evolve, integrating renewable energy solutions like off-grid solar power plants will play a crucial role in achieving long-term environmental sustainability and operational efficiency.

In conclusion, Rio Tinto's completion of the largest off-grid solar power plant in Canada's Northwest Territories marks a significant milestone in the mining industry's transition towards renewable energy. By harnessing solar power to reduce reliance on diesel generators, the company not only improves operational efficiency and environmental stewardship but also adds to momentum from corporate power purchase agreements like RBC's Alberta solar deal, setting a positive example for sustainable development in remote regions. As global demand for responsible mining practices grows, initiatives like Rio Tinto's off-grid solar project demonstrate the potential of renewable energy to drive positive change in resource-intensive industries.

British Columbia electricity rate increase will raise BC Hydro bills 3.75% over 2025-2026 to fund infrastructure, Site C, and clean energy, balancing affordability, reliability, and energy security while keeping prices below the North American average.

Key Points

BC will raise BC Hydro rates 3.75% in 2025-2026, about $3.75/month, to fund grid upgrades, Site C, and clean energy.

✅ 3.75% over 2025-2026; about $3.75/month on $100 average bill

✅ Funds Site C, grid maintenance, and clean energy capacity

✅ Keeps BC Hydro rates below North American averages

British Columbia's electricity rates will experience a 3.75% increase over the next two years, following an earlier 3% rate increase approval that set the stage, as confirmed by the provincial government on March 17, 2025. The announcement was made by Minister of Energy and Climate Solutions, Adrian Dix, who emphasized the decision's necessity for maintaining BC Hydro’s infrastructure while balancing affordability for residents.

For most households, the increase will amount to an additional $3.75 per month, based on an average BC Hydro bill of $100, though some coverage framed an earlier phase as a BC Hydro $2/month proposal that later evolved. While this may seem modest, the increase reflects a broader strategy to stabilize the utility's rates amidst economic challenges and ensure long-term energy security for the province.

Reasons Behind the Rate Hike

The rate increase comes during a period of rising costs in both global markets and local economies. According to Dix, the economic uncertainty stemming from trade dynamics and inflation has forced the government to act. Despite these pressures, and after a prior B.C. rate freeze to moderate impacts, the increase remains below cumulative inflation over the last several years, a move designed to shield consumers from the full force of these economic changes.

Dix also noted that, when adjusted for inflation, electricity rates in British Columbia in 2025 are effectively at the same price they were four decades ago. This stability, he argued, underscores the provincial government’s commitment to keeping rates as low as possible for residents, even as operating costs rise.

“We must take urgent action to protect British Columbians from the uncertainty posed by rising costs while building a strong, resilient electricity system for the long-term benefit of B.C.’s energy independence,” Dix said. He also highlighted the government's approach to minimizing the financial burden on consumers by keeping electricity costs well below the North American average.

Infrastructure and Maintenance Costs

The primary justification for the rate increase is to allow BC Hydro to continue its critical infrastructure development, including the Site C hydroelectric project, which is expected to become operational in the coming years. The increased costs of maintaining and upgrading the province's electricity grid also contribute to the need for higher rates.

The Site C project, a massive hydroelectric dam under construction on the Peace River, is expected to provide a substantial increase in clean, renewable energy capacity. However, such large-scale projects require significant investment and maintenance, both of which have contributed to the increased operating costs for BC Hydro.

A Strategic Move for Rate Stability

The provincial government has been clear that the rate increase will allow for a continuation of infrastructure development while keeping the rates manageable for consumers. The 3.75% increase will be spread across two years, with the first hike scheduled for April 1, 2025, reflecting the typical April rate changes BC Hydro implements, and the second for April 1, 2026.

Dix confirmed that the rate hike would still keep electricity costs among the lowest in North America, noting that British Columbians pay about half of what residents in Alberta pay for electricity. This is part of a broader effort by the provincial government to provide stable energy pricing while bolstering the transition to clean energy solutions, such as the Site C project and other renewable energy initiatives.

Addressing Public Concerns

Although the government has framed the increase as a necessary measure to ensure the province's long-term energy independence and reliability, the rate hikes are likely to face scrutiny from residents, particularly those already struggling with the rising cost of living, even as provinces like Ontario face their own Ontario hydro rate increase pressures this fall.

Public reactions to utility rate increases are often contentious, as residents feel the pressure of rising prices across various sectors, from housing to healthcare. However, the government has promised that the new rates will remain manageable, especially considering the relatively low rate increases compared to inflation and other regions where Manitoba Hydro scaled back a planned increase to temper impacts.

Furthermore, the increase comes as part of a broader strategy that aims to keep the overall impact on consumers as low as possible. Minister Dix emphasized that these rate increases were intended to ensure the continued reliability of BC Hydro’s services, without overwhelming ratepayers.

Long-Term Goals

Looking ahead, the province's strategy centers on not only maintaining affordable electricity rates but also reinforcing the importance of renewable energy, while some jurisdictions consider a 2.5% annual increase plan over multiple years to stabilize their grids. As climate change becomes an increasingly pressing issue, BC’s investments in clean energy projects like Site C aim to provide sustainable power for generations to come.

The government’s long-term vision involves building a resilient, energy-independent province that can weather future economic and environmental challenges. In this context, the rate increases are framed not just as a response to immediate inflationary pressures but as a necessary step in preparing BC’s energy infrastructure for the future.

The 3.75% rate increase set for 2025 and 2026 represents a balancing act between managing the financial health of BC Hydro and protecting consumers from higher costs. While the increase will have a modest effect on household bills, the long-term goal is to build a more robust and sustainable electricity system for British Columbia’s future. Through investments in clean energy and strategic infrastructure development, the province aims to keep electricity rates competitive while positioning itself as a leader in energy independence and climate action.

PJM and MISO Electricity-Market Reforms promise consumer savings by enabling renewables, wind, solar, and storage participation in wholesale markets, enhancing grid flexibility, reliability services, and real-time pricing across the Midwest, Great Lakes, and Mid-Atlantic.

Key Points

Market rule updates enabling renewables and storage, improving reliability and lowering consumer costs.

✅ Removes barriers to renewables, storage, demand response

✅ Improves intermarket links and real-time price signals

✅ Rewards flexible resources and reliability services

Electricity-market reforms to enable more renewables generation and storage in the Midwest, Great Lakes, and Mid-Atlantic could save consumers in the US and Canada more than $6.9 billion a year, according to a new report.

The findings may have major implications for consumer groups, large industrial companies, businesses, and homeowners in those regions, said the Wind-Solar Alliance, (WSA), which commissioned the Customer Focused and Clean report.

The WSA is a non-profit organisation supporting the growth of renewables. American Wind Energy Association CEO Tom Kiernan is listed as WSA secretary, amid ongoing debates about the US wind market today.

"Consumers are looking for clean energy, affordable and reliable energy that will keep their monthly electricity bills low," said Kristin Munsch, president of the Board of the Consumer Advocates of the PJM States, which represents over 65 million consumers in 13 states.

"There is great potential to achieve those goals with the cost-effective integration of wind, solar and battery storage plants into our wholesale power markets."

The report found the average residential customer in the PJM and Midcontinent Independent System Operator (MISO) regions, covering 29 US states and the Canadian province of Manitoba, could each save up to $48 a year as lower wholesale electricity prices materialize with significantly more wind, solar and storage on the grid.

The average annual home electricity, for example in New Jersey, in the PJM region, was just over $106 in 2018, according to the US Energy Information Administration.

The latest report quantifies the findings of a previous one for the WSA, published in November 2018, which found that outdated wholesale market rules in the US were preventing full participation by renewable energy, including wind power.

Outdated rules

"The existing wholesale power market rules were largely developed for slower-to-react conventional generators, such as coal and nuclear plants," said Michael Milligan, president of Milligan Grid Solutions and co-author of the new report.

"This report demonstrates the benefits of updating the rules to better accommodate the characteristics and potential contributions of wind and solar and other newer sources of low-cost generation."

With more renewables generation on the grid, customers would benefit the most from increasing power-system flexibility through market structures, the new report concluded. It called for the removal of artificial barriers preventing renewables, storage and demand response from participating in markets.

The report also advocated improving the connections between markets, thereby lowering transaction costs of imports and exports between neighbouring systems.

"There are currently artificial barriers that are preventing the full participation of renewables, storage and other new technologies in the PJM and MISO markets," said Michael Goggin, vice president of Grid Strategies and co-author of the report.

"Providing consumers with a real-time price signal that allows them to adjust their demand, rewarding flexible resources for their capabilities through improved market design, and allowing renewable and storage resources to participate in reliability-services markets would yield the greatest consumer benefits," he said.

PJM and MISO, which incorporate some of the windiest areas of the country, are currently reviewing their market designs as part of a broader grid overhaul underway.

China Renewable Energy Law drives growth in wind power, solar thermal, and photovoltaic capacity, supporting grid integration and five-year plans, even as China leads CO2 emissions, with policy incentives, compliance inspections, and national resource assessments.

Key Points

A legal framework that speeds wind, solar thermal, and PV growth in China via mandates, incentives, and grid rules.

✅ 2018 renewables: 1.87T kWh, 26.7% of national power

✅ Over 100 State Council policies enabling deployment

✅ Law inspections and regional oversight across six provinces

China leads renewable energies, installing more wind power, solar thermal and photovoltaic than any other country, as seen in the China solar PV growth reported in 2016, but also leads CO2 emissions, and much remains to be done.

The effective application of Chinas renewable energy law has boosted the use of renewable energy in the country and facilitated the rapid development of the sector, as solar parity across Chinese cities indicates, a report said.

The report on compliance with renewable energy law was presented today at the current bimonthly session of the Standing Committee of the National Peoples Assembly (APN).

Electricity generated by renewable energy amounted to about 1.87 trillion kilowatts per hour in 2018, representing 26.7 percent of Chinas total energy production in the year, aligning with trends where wind and solar doubling globally over five years, the report said.

Ding Zhongli, vice president of the NPC Standing Committee, presented the report to the legislators at the second plenary meeting of the session.

An inspection of the law enforcement was carried out from August to November, as U.S. renewables hit 28% record showed momentum elsewhere. A total of 21 members of the NPC Standing Committee and the NPC Environmental Protection and Resource Conservation Committee, as well as national legislators, traveled to six regions at the provincial level on inspection visits. Twelve legislative bodies at the provincial level inspected the law enforcement efforts in their jurisdictions.

The relevant State Council agencies have implemented more than 100 regulations and policies to foster a good policy environment for the development of renewable energy, as seen in markets where U.S. renewable electricity surpassed coal in 2022. Local regulations have also been formulated based on local conditions, according to the report.

In accordance with the law, a thorough investigation of the national conditions of renewable energy resources was undertaken.

In 2008 and 2014 atlas of solar energy resources and wind energy evaluation of China were issued. The relevant agencies of the State Council have also implemented five-year plans for the development of renewable energy, which have provided guidance to the sector, while countries like Ireland's one-third green power target remain in focus within four years.

The main provisions of the law have been met, the law has been effectively applied and the purpose of the legislation has been met, and this momentum is echoed abroad, with U.S. renewables near one-fourth according to projections, Ding said.

San Juan Generating Station eyed for $1 coal-plant sale, as Farmington and Acme propose CCS retrofit, meeting emissions caps and renewable mandates by selling captured CO2 for enhanced oil recovery via a nearby pipeline.

Key Points

A New Mexico coal plant eyed for $1 and a CCS retrofit to cut emissions and sell CO2 for enhanced oil recovery.

✅ $400M-$800M CCS retrofit; 90% CO2 capture target

✅ CO2 sales for enhanced oil recovery; 20-mile pipeline gap

✅ PNM projects shutdown savings; renewable and emissions mandates

One dollar. That’s how much an aging New Mexico coal plant is worth. And by some estimates, even that may be too much.

Acme Equities LLC, a New York-based holding company, is in talks to buy the 847-megawatt San Juan Generating Station for $1, after four of its five owners decided to shut it down. The fifth owner, the nearby city of Farmington, says it’s pursuing the bargain-basement deal with Acme to avoid losing about 1,600 direct and indirect jobs in the area amid a broader just transition debate for energy workers.

We respectfully disagree with the notion that the plant is not economical

Acme’s interest comes as others are looking to exit a coal industry that’s been plagued by costly anti-pollution regulations. Acme’s plan: Buy the plant "at a very low cost," invest in carbon capture technology that will lower emissions, and then sell the captured CO2 to oil companies, said Larry Heller, a principal at the holding group.

By doing this, Acme “believes we can generate an acceptable rate of return,” Heller said in an email.

Meanwhile, San Juan’s majority owner, PNM Resources Inc., offers a distinctly different view, echoing declining coal returns reported by other utilities. A 2022 shutdown will push ratepayers to other energy alternatives now being planned, saving them about $3 to $4 a month on average, PNM has said.

“We could not identify a solution that would make running San Juan Generating Station economical,” said Tom Fallgren, a PNM vice president, in an email.

The potential sale comes as a new clean-energy bill, supported by Governor Lujan Grisham, is working its way through the state legislature. It would require the state to get half of its power from renewable sources by 2030, and 100 percent by 2045, even as other jurisdictions explore small modular reactor strategies to meet future demand. At the same time, the legislation imposes an emissions cap that’s about 60 percent lower than San Juan’s current levels.

In response, Acme is planning to spend $400 million to $800 million to retrofit the facility with carbon capture and sequestration technology that would collect carbon dioxide before it’s released into the atmosphere, Heller said. That would put the facility into compliance with the pending legislation and, at the same time, help generate revenue for the plant.

The company estimates the system would cut emissions by as much as 90 percent, and the captured gas could be sold to oil companies, which uses it to enhance well recovery. The bottom line, according to Heller: “A winning financial formula.”

It’s a tricky formula at best. Carbon-capture technology has been controversial, even as new coal plant openings remain rare, expensive to install and unproven at scale. Additionally, to make it work at the San Juan plant, the company would need to figure out how to deliver the CO2 to customers since the nearest pipeline is about 20 miles (32 kilometers) away.

Reducing costs

Acme is also evaluating ways to reduce costs at San Juan, Heller said, including approaches seen at operators extending the life of coal plants under regulatory scrutiny, such as negotiating a cheaper coal-supply contract and qualifying for subsidies.

Farmington’s stake in the plant is less than 10 percent. But under terms of the partnership, the city — population 45,000 — can assume full control of San Juan should the other partners decide to pull out, mirroring policy debates over saving struggling nuclear plants in other regions. That’s given Farmington the legal authority to pursue the plant’s sale to Acme.

At the end of the day, nobody wants the energy

“We respectfully disagree with the notion that the plant is not economical,” Farmington Mayor Nate Duckett said by email. Ducket said he’s in better position than the other owners to assess San Juan’s importance “because we sit at Ground Zero.”

The city’s economy would benefit from keeping open both the plant and a nearby coal mine that feeds it, according to Duckett, with operations that contribute about $170 million annually to the local area.

While the loss of those jobs would be painful to some, Camilla Feibelman, a Sierra Club chapter director, is hard pressed to see a business case for keeping San Juan open, pointing to sector closures such as the Three Mile Island shutdown as evidence of shifting economics. The plant isn’t economical now, and would almost certainly be less so after investing the capital to add carbon-capture systems.

Canada Economic Crossroads highlights bank earnings trends, interest rates, loan delinquencies, EV tariffs on Chinese imports, domestic manufacturing, Algoma Steel decarbonization, sustainability, and housing market risks shaping growth, investment, consumer prices, and climate policy.

Key Points

An overview of how bank earnings, EV tariffs, and Algoma Steel's transition shape Canada's economy.

✅ Higher rates lift margins but raise delinquencies and housing risks

✅ EV tariffs aid domestic makers but pressure consumer prices

✅ Algoma invests to decarbonize, boosting efficiency and compliance

In a complex economic landscape, recent developments have brought attention to several pivotal issues affecting Canada's business sector. The Globe and Mail’s latest report delves into three major topics: the latest bank earnings, the implications of new tariffs on Chinese electric vehicles (EVs), and Algoma Steel’s strategic maneuvers. These factors collectively paint a picture of the challenges and opportunities facing Canada's economy.

Bank Earnings Reflect Economic Uncertainty

The recent financial reports from major Canadian banks have revealed a mixed picture of the nation’s economic health. As the Globe and Mail reports, earnings results show robust performances in some areas while highlighting growing concerns in others. Banks have generally posted strong quarterly results, buoyed by higher interest rates which have improved their net interest margins. This uptick is largely attributed to the central bank's monetary policies aimed at combating inflation and stabilizing the economy.

However, the positive earnings are tempered by underlying economic uncertainties. Rising loan delinquencies and a slowing housing market are areas of concern. Increased interest rates, while beneficial for banks’ margins, have also led to higher borrowing costs for consumers and businesses. This dynamic has the potential to impact overall economic growth and consumer confidence.

Tariffs on Chinese EVs: A Strategic Shift

Another significant development is the imposition of new tariffs on Chinese electric vehicles. This move is part of a broader strategy to protect domestic automotive industries and address trade imbalances, aligning with public support for tariffs in key sectors. The tariffs are expected to increase the cost of Chinese EVs in Canada, which could have several implications for the market.

On one hand, the tariffs might provide a temporary boost to Canadian and North American manufacturers by reducing competition from lower-priced Chinese imports. This protectionist measure could encourage investments in local production and innovation, mirroring tariff threats boosting support for energy projects in other sectors. However, the increased cost of Chinese EVs may also lead to higher prices for consumers, potentially slowing the adoption of electric vehicles—a critical goal in Canada’s climate strategy.

The tariffs come at a time when the Canadian government is keen on accelerating the transition to electric mobility to meet its environmental targets, even as a critical crunch in electrical supply raises questions about grid readiness. Balancing the protection of domestic industries with the broader goal of reducing emissions will be a significant challenge moving forward.

Algoma Steel’s Strategic Evolution

In the steel industry, Algoma Steel has been making headlines with its strategic initiatives aimed at transforming its operations, in a broader shift toward clean grids and industrial decarbonization. The Globe and Mail highlights Algoma Steel's efforts to modernize its production processes and shift towards more sustainable practices. This includes significant investments in technology and infrastructure to enhance production efficiency and reduce environmental impact.

Algoma's focus on reducing carbon emissions aligns with broader industry trends towards sustainability. The company’s efforts are part of a larger push within the steel sector to address climate change and meet regulatory requirements. As one of Canada’s leading steel producers, Algoma’s actions could set a precedent for the industry, showcasing how traditional manufacturing sectors can adapt to evolving environmental standards.

Implications and Future Outlook

The interplay of these developments reflects a period of significant transition for Canada's economy, shaped in part by U.S. policy where Biden is seen as better for Canada's energy sector by some analysts. For banks, the challenge will be to navigate the balance between profitability and potential risks from a changing economic environment. The new tariffs on Chinese EVs represent a strategic shift with mixed implications for the automotive market, potentially influencing both domestic production and consumer prices. Meanwhile, Algoma Steel’s push towards sustainability could serve as a model for other industries seeking to align with environmental goals.

As these issues unfold, stakeholders across sectors will need to stay informed and adaptable. For policymakers, the challenge will be to support domestic industries while fostering innovation and sustainability, including the dilemma over electricity rates and innovation they must weigh. For businesses, the focus will be on navigating financial pressures and leveraging opportunities for growth. Consumers, in turn, will face the impact of these developments in their daily lives, from the cost of borrowing to the price of electric vehicles.

In summary, Canada’s current economic landscape is characterized by a blend of financial resilience, strategic adjustments, and evolving industry practices, amid policy volatility such as a tariff threat delaying Quebec's green energy bill earlier this year. As the country navigates these crossroads, the outcomes of these developments will play a crucial role in shaping the future economic environment.
