New pollution figures confirm the need to shut Ontario's coal-fuelled generating stations as soon as possible, a watchdog group says.

Greenhouse gas emissions from the coal stations increased by more than 90 per cent from 1995 to 2005, according to a report from the Ontario Clean Air Alliance, a coalition of environment, energy, consumer and health organizations.

They now account for 40 per cent of the province's emissions of carbon dioxide – the main greenhouse gas – from industrial sources.

The stations continue to contribute a large proportion of many other air pollutants, including those that create smog, as well as large quantities of ash that contains mercury, arsenic and other toxic metals.

"The amount of pollution created by Ontario Power Generation's... plants is staggering. For many pollutants (they) tower above thousands of other facilities in the province," the report says. And, it argues, attempts to combat one type of pollution almost invariably lead to increases in others.

The report, "OPG: Ontario's Pollution Giant," was compiled using 2005 figures from the federal government's National Pollutants Release Inventory and its Greenhouse Gas Emissions Reporting Program, which track major industrial sources.

Its calculations show that, when it comes to air pollution, the coal-fuelled stations also account for:

- 22 per cent of Ontario's emissions that create smog and acid rain. Those pollutants include tiny particles, nitrogen oxides and sulphur dioxide.

- 24 per cent of emissions of the chemicals classified as toxic under the Canadian Environmental Protection Act. Many of these chemicals are believed to interfere with human reproduction and development. That includes 36 per cent of the mercury, which can damage the nervous system in humans.

As well, the coal stations produce about 3.4 million kilograms of toxic wastes contained in ash that's either landfilled on site or shipped elsewhere – mainly to kilns used to make cement at Bath and St. Mary's, Ont., and in Michigan, where it is burned as a fuel.

The alliance doesn't know whether these solid wastes pose a health threat, but there are concerns, particularly with kiln emissions, said alliance chair Jack Gibbons. "Kilns are significant sources of mercury."

Once again, in 2005, OPG's Nanticoke generating station, on the north shore of Lake Erie, was the province's biggest single source of carbon dioxide, particulates, nitrogen oxides and mercury. Nanticoke was second as a source of sulphur dioxide.

OPG operated five coal-fuelled stations until April 2005 when Lakeview, in southern Mississauga, was closed. The others are near Sarnia and in the Northern Ontario communities of Thunder Bay and Atikokan.

OPG spokesperson John Earl said the agency will continue to run the stations as efficiently as possible, and according to regulatory guidelines.

Ontario government wants new gas plants to boost electricity production

Ontario Gas Plant Expansion aims to boost grid reliability as nuclear refurbishments proceed, using natural gas to meet electricity demand, despite critics urging renewables, energy storage, and efficiency to reduce carbon emissions, protecting investment growth.

 

Key Points

Ontario plan to expand gas plants for reliability during nuclear outages, sparking debate on emissions and clean options.

✅ IESO data: gas share rose from 4% (2017) to 10.4% (2022).

✅ Government cites nuclear refurbishments and demand growth.

✅ Critics propose storage, wind, solar, and efficiency.

 

The Ontario government is preparing to expand gas-fired power plants in Ontario; a move critics say will make the province's electricity system dirtier and could eventually leave taxpayers on the hook.

The province is currently soliciting bids for additional gas-fired electricity generation, which means new gas plants get built, or existing gas plants get expanded. 

It's poised to be Ontario's biggest increase in the gas-fired power supply in more than a decade since the previous Liberal government scrapped two gas plants, in Mississauga and Oakville, at a cost the auditor general pegged at around $1 billion. 

Doug Ford's energy minister, Todd Smith, says Ontario needs gas plants now to help meet an expected surge in demand for electricity as the province faces a supply shortfall in the coming years and to provide power while some units of the province's nuclear stations are down for refurbishment. 

"It's really important to have natural gas as an insurance policy to keep the lights on and provide the reliability that we need," Smith said in an interview. 

"We need natural gas for the short term, especially to get us through these refurbishments."

The portion of Ontario's electricity supply that comes from natural gas matters for the environment and the province's economy. Manufacturing companies increasingly seek clean power that emits as little carbon dioxide as possible. 

The portion of Ontario's electricity supply that comes from natural gas matters for the environment and the province's economy. Manufacturing companies increasingly seek a power supply that emits as little carbon dioxide as possible. 

Increasing the amount of gas-fired generation in the electricity system puts Ontario's ability to attract such investments at risk as it complicates balancing demand and emissions across the grid, says Evan Pivnick, program manager with Clean Energy Canada, a think tank. 

"Building new natural gas (power plants) in Ontario today should be seen as an absolute last resort for meeting our energy needs," said Pivnick in an interview. 

Ontario's electricity system has among the lowest rates of CO2 emissions in North America, with roughly half of the annual supply provided by nuclear power, one-quarter from hydro dams, and one-tenth from wind turbines. 

However, Ontario's gas plants have produced a growing amount of electricity in recent years, despite an early report exploring a gas halt by the minister, and that trend will continue if new gas plants are built. 

In 2017, gas- and oil-fired generation provided just four percent of Ontario's electricity supply, according to figures from the provincial agency that manages the grid, the Independent Electricity System Operator (IESO). 

By 2022, that figure reached 10.4 percent. 

Ontario doesn't need new gas plants to meet the electricity demand, says Bryan Purcell, vice president of policy and programs at The Atmospheric Fund. This agency invests in low-carbon projects in the Greater Toronto and Hamilton Area. 

"We're quite concerned about where Ontario's electric grid is going," said Purcell. "Thankfully, there's still time to adjust course and look at other options." 

According to Purcell and Pivnick, those options to avoid gas could include power storage (in which excess generated energy is stored for later use when electricity demand rises), wind and solar projects, or energy efficiency and conservation programs.

Putting Africa on the path to universal electricity access

West and Central Africa Electricity Access hinges on utility reform, renewable energy, off-grid solar, mini-grids, battery storage, and regional grid integration, lowering costs, curbing energy poverty, and advancing SDG7 with sustainable, reliable power solutions.

 

Key Points

Expanding reliable power via renewables, grid trade, and off-grid systems to cut energy poverty and unlock inclusive growth.

✅ Utility reform lowers costs and improves service reliability

✅ Regional grid integration enables clean, least-cost power trade

✅ Off-grid solar and mini-grids electrify remote communities

 

As commodity prices soar and leaders around the world worry about energy shortages and prices of gasoline at the pump, millions of people in Africa still lack access to electricity.  One-half of the people on the continent cannot turn on a fan when temperatures go up, can’t keep food cool, or simply turn the lights on. This energy access crisis must be addressed urgently.

In West and Central Africa, only three countries are on track to give every one of their people access to electricity by 2030. At this slow pace, 263 million people in the region will be left without electricity in ten years.  West Africa has one of the lowest rates of electricity access in the world; only about 42% of the total population, and 8% of rural residents, have access to electricity.

These numbers, some far too big, others far too small, have grave consequences. Electricity is an important step toward enhancing people’s opportunities and choices. Access is key to boosting economic activity and contributes to improving human capital, which, in turn, is an investment in a country’s potential.  

Without electricity, children can’t do their schoolwork at night. Businesspeople can’t get information on markets or trade with each other. Worse, as the COVID-19 pandemic has shown so starkly, limited access to energy constrains hospital and emergency services, further endangering patients and spoiling precious medicine.  

What will it take to power West and Central Africa?  
As the African continent recovers from COVID-19 impacts, now is the critical time to accelerate progress towards universal energy access to drive the region’s economic transformation, promote socio-economic inclusion, and unlock human capital growth. Without reliable access to electricity, the holes in a country’s social fabric can grow bigger, those without access growing disenchanted with inequality.  

Tackling the Africa region’s energy access crisis requires four bold approaches. 

First, this involves making utilities financially viable. Many power providers in the region are cash-strapped, operate dilapidated and aging generation fleet and infrastructure. Therefore, they can’t deliver reliable and affordable electricity to their customers, let alone deliver electricity to those that currently must rely on inadequate alternatives to electricity. Overall, fewer than half of the utilities in Sub-Saharan Africa recover their operating costs, resulting in GDP losses as high as four percent in some countries.

Improving the performance of national utilities and greening their power generation mix is a prerequisite to lowering the costs of supply, thus expanding electricity access to those currently unelectrified, usually lower-income and often remote households. 

In that effort — and this a critical second point — West and Central African countries need to look beyond their borders and further integrate their national utilities and grids to other systems in the region. The region has an abundance of affordable clean energy sources — hydropower in Guinea, Mali, and Cote d’Ivoire; high solar irradiation in the Sahel — but the regional energy market is fragmented. 

Without efficient regional trade, many countries are highly dependent on one or two energy resources and heavily reliant on inefficient, polluting generation sources, requiring fuel imports linked to volatile international oil prices.

The vision of an integrated regional power market in countries of the Economic Community of West African States (ECOWAS) is coming a step closer to reality thanks to an ambitious program of cross-border interconnection projects. If countries take full advantage of this grid, the share of the region’s electricity consumption traded across borders would more than double from 8 percent today to about 17 percent by 2030. Overall, regional power trade could lower the lifecycle cost of West Africa’s power generation system by about 10 percent and provide greener energy by 2030. 

Third, electrification efforts need to be open to private sector investments and innovations, such as renewables like solar energy and battery storage, which have made a tremendous impact in enabling access for millions of poor and underserved households.  Specifically, off-grid solar systems and mini-grids have become a proven reliable way to provide affordable modern electricity services, powering homes in rural communities, healthcare facilities, and schools.

Burkina Faso, which enjoys one of the best solar radiation conditions in the region, is a successful example of leveraging the transformative impact of solar energy and battery storage. With support from the World Bank, the country is deploying solar energy to power its national grid, as well as mini-grids and individual household systems. Solar power with battery storage is competitive in Burkina Faso compared to other technologies and its government was successful in attracting private sector investments to support this technology.

Last, achieving universal electricity access will involve significant commitment from political leaders, especially developing policies and regulations that can attract high-quality investments.  

A significant step in that direction was achieved at the World Bank’s 2020 Annual Meetings with a commitment to set up the Powering Transformation Platform in each African country. Through the platform, each government will set their country-specific vision, goals and metrics, track progress, and explore and exchange innovative ideas and emerging best practices according to their own national energy needs and plans. 

This platform will bring together the elements needed to bring electricity to all in West and Central Africa and help attract new financing.

Over the last 3 years, the World Bank has doubled its investments to increase electricity access rates in Central and West Africa.  We have committed more than $7.8 billion to support 40 electricity access programs, of which more than half directly support new electricity connections. These operations are expected to provide access to 16 million people. The aim is to increase electricity access rates in West and Central Africa from 50 percent today to 64 percent by 2026.

However, World Bank’s financing alone is not enough. Our estimates show that nearly $20 billion are required for universal electrification across Sub-Saharan Africa, aligning with calls to quadruple power investment to meet demand, with about $10 billion annually needed for West and Central Africa. 

Closing the funding gap will require mobilizing traditional and new partners, especially the private sector, which is willing to invest if enabling conditions are in place, as well as philanthropic capital, that can fill in the space in areas not yet commercially attractive. The World Bank is ready to play a catalytical role in leveraging new investments. 

This is vital as less than a decade remains to reach the 2030 SDG7 goal of ensuring electricity for all through affordable, reliable, and modern energy services. As headlines worldwide focus on soaring energy prices in the developed world, we cannot lose sight of the vast populations in Africa that still cannot access basic energy services. This is the true global energy crisis.

Quebec shatters record for electricity consumption once again

Hydro Quebec Power Consumption Record surges amid extreme cold, peak demand, and grid stress, as Hydro-Quebec urges energy conservation, load management, and reduced heating during morning and evening peaks across Montreal and southern Quebec.

 

Key Points

Quebec's grid hit 40,300 MW during an extreme cold snap, setting a new record and prompting conservation appeals.

✅ Lower thermostats 1-2 C in unused rooms during peak hours

✅ Delay dishwashers, dryers, and hot water use to off-peak

✅ Peak windows: 6-9 a.m. and 4-8 p.m.; import power if needed

 

Hydro Quebec says it has once again set a new record for power consumption, echoing record-breaking demand in B.C. in 2021 as extreme cold grips much of the province.

An extreme cold warning has been in effect across southern Quebec since Friday morning, straining the system, just as Calgary's electricity use soared during a frigid February, as Quebecers juggle staying warm and working from home.

Hydro Québec recorded consumption levels reaching 40,300 megawatts as of 8 a.m. Friday, breaking a previous record of 39,000 MW (with B.C. electricity demand hit an all-time high during a similar cold snap) that was broken during another cold snap on Jan 11. 

The publicly owned utility is now asking Quebecers to reduce their electricity consumption as much as possible today and tomorrow, a move consistent with clean electricity goals under federal climate pledges, predicting earlier in the morning the province would again reach an all-time high.

Reducing heating by just one or two degrees, especially in rooms that aren't being used, is one step that people can take to limit their consumption. They can also avoid using large appliances like the dishwasher and clothing dryer as often, and shortening the use of hot water. 

"They're small actions, but across millions of clients, it makes a difference," said Cendrix Bouchard, a spokesperson with Hydro Québec, while speaking with Tout un matin.

"We understand that asking this may pose challenges for some who are home throughout the day because they are working remotely, but if people are able to contribute, we appreciate it."

The best time to try and limit electricity usage is in the morning and evening, when electricity usage tends to peak, Bouchard said.

The province can import electricity from other regions if Quebec's system reaches its limits, even as the utility pursues selling to the United States as part of its long-term strategy, he added.

Temperatures dropped to –24 C in Montreal at 7 a.m., with a wind chill of –29 C. 

It will get colder across the south of the province through the evening and wind chills are expected to make it feel as cold as – 40 until Saturday morning, Environment Canada warned.

Those spending time outdoors are at a higher risk of frostbite and hypothermia.

"Frostbite can develop within minutes on exposed skin, especially with wind chill," Environment Canada said.

Conserving energy
Hydro-Québec has signed up 160,000 clients to a flexible billing plan similar to BC Hydro's winter payment plan that allows them to pay less for energy — as long as they use it during non-peak periods.

Quebec's energy regulator, the Régie de l'énergie, also forces crypto-currency mining operations to shut down for some hours  on peak-demand days, a topic where BC Hydro's approach to crypto mining has also drawn attention, Bouchard said.

Hydro-Québec says the highest consumption periods are usually between 6 a.m.-9 a.m. and 4 p.m.-8 p.m.

Vehicle-to-grid could be ‘capacity on wheels’ for electricity networks

Vehicle-to-Grid (V2G) enables EV batteries to provide grid balancing, flexibility, and demand response, integrating renewables with bidirectional charging, reducing peaker plant reliance, and unlocking distributed energy storage from millions of connected electric vehicles.

 

Key Points

Vehicle-to-Grid (V2G) lets EVs export power via bidirectional charging to balance grids and support renewables.

✅ Turns parked EVs into distributed energy storage assets

✅ Delivers balancing services and demand response to the grid

✅ Cuts peaker plant use and supports renewable integration

 

“There are already many Gigawatt-hours of batteries on wheels”, which could be used to provide balance and flexibility to electrical grids, if the “ultimate potential” of vehicle-to-grid (V2G) technology could be harnessed.

That’s according to a panel of experts and stakeholders convened by our sister site Current±, which covers the business models and technologies inherent to the low carbon transition to decentralised and clean energy. Focusing mainly on the UK grid but opening up the conversation to other territories and the technologies themselves, representatives including distribution network operator (DNO) Northern Powergrid’s policy and markets director and Nissan Europe’s director of energy services debated the challenges, benefits and that aforementioned ultimate potential.

Decarbonisation of energy systems and of transport go hand-in-hand amid grid challenges from rising EV uptake, with vehicle fuel currently responsible for more emissions than electricity used for energy elsewhere, as Ian Cameron, head of innovation at DNO UK Power Networks says in the Q&A article.

“Furthermore, V2G technology will further help decarbonisation by replacing polluting power plants that back up the electrical grid,” Marc Trahand from EV software company Nuvve Corporation added, pointing to California grid stability initiatives as a leading example.

While the panel states that there will still be a place for standalone utility-scale energy storage systems, various speakers highlighted that there are over 20GWh of so-called ‘batteries on wheels’ in the US, capable of powering buildings as needed, and up to 10 million EVs forecast for Britain’s roads by 2030.

“…it therefore doesn’t make sense to keep building expensive standalone battery farms when you have all this capacity on wheels that just needs to be plugged into bidirectional chargers,” Trahand said.

New president at Manitoba Hydro to navigate turmoil at Crown corporation

Jay Grewal Manitoba Hydro Appointment marks the first woman CEO at the Crown utility, amid debt, rate increase plans, privatization debate, and Metis legal challenge, following board turmoil and Premier Pallister's strained relations.

 

Key Points

The selection of Jay Grewal as Manitoba Hydro's first woman CEO amid debt, rate hikes, and legal disputes.

✅ First woman CEO of Manitoba Hydro

✅ Faces debt, rate hikes, and project overruns

✅ Amid privatization debate and Metis legal action

 

The Manitoba government has appointed a new president and chief executive officer at its Crown-owned energy utility.

Jay Grewal becomes the first woman to head Manitoba Hydro, and takes over the top spot as the utility faces mounting financial challenges, rising electricity demand and turmoil.

Grewal has previously held senior roles at Capstone Mining Corp and B.C. Hydro, and is currently president of the Northwest Territories Power Corporation.

She will replace outgoing president Kelvin Shepherd, who recently announced he is retiring, on Feb. 4.

The utility was hit by the sudden resignations of nine of its 10 board members in March, who said they had been unable to meet with Premier Brian Pallister to discuss pressing issues like servicing energy-intensive customers facing the utility.

Manitoba Hydro is also in the middle of a battle between the Progressive Conservative government and the Manitoba Metis Federation over the cancellation of two agreements that would have given the Metis $87 million.

The federation has launched a legal challenge over one deal and says its likely going to do the same over the second agreement.

Grewal also takes over the utility at a time when it has racked up billions of dollars in debt building new generating stations and transmission lines. Manitoba Hydro has told the provincial regulatory agency it needs rate increases of nearly eight per cent a year for the next few years to help pay for the projects.

The utility also exports electricity, with deals such as SaskPower's purchase agreement expanding sales to Saskatchewan.

"Ms. Grewal is a proven leader, with extensive senior leadership experience in the utility, resource and consulting sectors," Crown Services Minister Colleen Mayer said in a written statement Thursday.

The Opposition New Democrats said Grewal's appointment is a sign the government wants to privatize Manitoba Hydro. Grewal's time at B.C. Hydro coincided with the privatization of some parts of that Crown utility, the NDP said.

The B.C. premier at the time, Gordon Campbell, was recently hired by Manitoba to review two major projects that ran over-budget and have added to the provincial debt.

NDP Leader Wab Kinew asked Pallister in the legislature Thursday to promise not to privatize Manitoba Hydro. Pallister would only point to a law that requires a referendum to be held before a Crown entity can be sold off.

"We stand by that (law)," Pallister said. "We believe Manitobans are the proper decision-makers in respect of any of the future structuring of Manitoba Hydro."

Canada to spend $2M on study to improve Atlantic region's electricity grid

Atlantic Clean Power Superhighway outlines a federally backed transmission grid upgrade for Atlantic Canada, adding 2,000 MW of renewable energy via interprovincial ties, improved hydro access from Quebec and Newfoundland and Labrador, with utility-regulator funding.

 

Key Points

A federal-provincial plan upgrading Atlantic Canada's grid to deliver 2,000 MW of renewables via interprovincial links.

✅ $2M technical review to rank priority transmission projects

✅ Target: add 2,000 MW renewable power to Atlantic grid

✅ Cost-sharing by utilities, regulators, and federal-provincial funding

 

The federal government will spend $2 million on an engineering study to improve the Atlantic region's electricity grid.

The study was announced Friday at a news conference held by 10 federal and provincial politicians at a meeting of the Atlantic Growth Strategy in Halifax, which includes ongoing regulatory reform efforts for cleaner power in Atlantic Canada.

The technical review will identify the most important transmission projects including inter-provincial ties needed to move electricity across the region.

Nova Scotia Premier Stephen McNeil said the results are expected in July.

Provinces will apply to the federal government for federal funding to build the infrastructure. Utilities in each province will be expected to pay some portion of the cost by applying to respective regulators, but what share falls to ratepayers is not known.

​Federal Intergovernmental Affairs Minister Dominic LeBlanc characterized the grid improvements as something that will cost hundreds of millions of dollars.

He said the study was the first step toward "a clean power superhighway across the region.

"We have a historic opportunity to quickly get to work on upgrading ultimately a whole series of transmission links of inter-provincial ties. That's something that the government of Canada would be anxious to work with in terms of collaborating with the provinces on getting that right."

Premier McNeil referred specifically to improving hydro access from Quebec and Newfoundland and Labrador.

For context, a massive cross-border hydropower line to New York is planned, illustrating the scale of projects under consideration.

 

Goal of 2,000 megawatts

McNeil said the goal was to bring an additional 2,000 megawatts of renewable electricity into the region.

"I can't stress to you enough how critical this will be for the future economic success and stability of Atlantic Canada, especially as Atlantic grids face intensifying storms," he said.

Federal Immigration Minister Ahmed Hussen also announced a pilot project to attract immigrant workers will be extended by two years to the end of 2021.

International graduate students will be given 24 months to apply under the program — a one-year increase.
