Ontario Pumped Storage advances as Ontario's largest energy storage project, delivering clean electricity, long-duration capacity, and grid reliability for peak demand, led by TC Energy and Saugeen Ojibway Nation, with IESO review underway.
Key Points
A long-duration storage project in Meaford storing clean power for peak demand, supporting Ontario's emission-free grid.
✅ Stores clean electricity to power 1M homes for 11 hours
✅ Partnership: TC Energy and Saugeen Ojibway Nation
✅ Pending IESO review and OEB regulation decisions
In a bid to accelerate the province's ambitions for clean economic growth, TC Energy Corporation has announced significant progress in the development of the Ontario Pumped Storage Project. The Government of Ontario in Canada has unveiled a plan to address growing energy needs as a sustainable road map aimed at achieving an emission-free electricity sector, and as part of this plan, the Ministry of Energy is set to undertake a final evaluation of the proposed Ontario Pumped Storage Project. A decision is expected to be reached by the end of the year.
Ontario Pumped Storage is a collaborative effort between TC Energy and the Saugeen Ojibway Nation. The project is designed to be Ontario's largest energy storage initiative, capable of storing clean electricity to power one million homes for 11 hours. As the province strives to transition to a cleaner electricity grid by embracing clean power across sectors, long duration storage solutions like Ontario Pumped Storage will play a pivotal role in providing reliable, emission-free power during peak demand periods.
The success of the Project hinges on the approval of TC Energy's board of directors and a fruitful partnership agreement with the Saugeen Ojibway Nation. TC Energy is aiming for a final investment decision in 2024, as Ontario confronts an electricity shortfall in the coming years, with the anticipated in-service date being in the early 2030s, pending regulatory and corporate approvals.
“Ontario Pumped Storage will be a critical component of Ontario’s growing clean economy and will deliver significant benefits and savings to consumers,” said Corey Hessen, Executive Vice-President and President, TC Energy, Power and Energy Solutions. “Ontario continues to attract major investments that will have large power needs — many of which are seeking zero-emission energy before they invest. We are pleased the government is advancing efforts to recognize the significant role that long duration storage plays — firming resources, including new gas plants under provincial consideration, will become increasingly valuable in supporting a future emission-free electricity system.”
The Municipality of Meaford also expressed its support for the project, recognizing the positive impact it could have on the local economy and the overall electricity system of Ontario. Additionally, various stakeholders, including LiUNA OPDC, LiUNA Local 183, and the Ontario Chamber of Commerce, lauded the potential for job creation, training opportunities, and resilient energy infrastructure as Ontario seeks new wind and solar power to ease a coming electricity supply crunch.
The timeline for Ontario Pumped Storage's progress includes a final analysis by the Independent Electricity System Operator (IESO) to confirm its role in Ontario's electricity system and in balancing demand and emissions during the transition, to be completed by 30 September 2023. Concurrently, the Ministry of Energy will engage in consultations on the potential regulation of the Project via the Ontario Energy Board, while debates over clean, affordable electricity intensify ahead of the Ontario election, with a final determination scheduled for 30 November 2023.
BC Hydro electricity demand decline reflects COVID-19 impacts across British Columbia, with reduced industrial load, full reservoirs, strategic spilling, and potential rate increases, as hydropower plants adjust operations at Seven Mile, Revelstoke, and Site C.
Key Points
A 10% COVID-19-driven drop in BC power use, prompting reservoir spilling, plant curtailment, and potential rate hikes.
✅ 10% load drop; industrial demand down 7% since mid-March
✅ Reservoirs near capacity; controlled spilling to mitigate risk
✅ Possible rate hikes; Site C construction continues
Elecricity demand is down 10 per cent across British Columbia, an unprecedented decline in commercial electricity consumption sparked by the COVID-19 pandemic, according to a BC Hydro report.
Power demand across hotels, offices, recreational facilities and restaurants have dwindled as British Columbians self isolate, and bill relief for residents and businesses was introduced during this period.
The shortfall means there's a surplus of water in reservoirs across the province.
"This drop in load in addition to the spring snow melt is causing our reservoirs to reach near capacity, which could lead to environmental concerns, as well as public safety risks if we don't address the challenges now," said spokesperson Tanya Fish.
Crews will have to strategically spill reservoirs to keep them from overflowing, a process that can have negative impacts on downstream ecosystems. Excessive spilling can increase fish mortality rates.
Spilling is currently underway at the Seven Mile and Revelstoke reservoirs. In addition, several small plants have been shut down.
Site C and hydro rates According to the report, titled Demand Dilemma, the decline could continue into April 2021 and drop by another two per cent, even as a regulator report alleged BC Hydro misled oversight bodies.
Major industry — forestry, mining and oil and gas — accounts for about 30 per cent of BC Hydro's overall electricity load. Energy demand from these customers has dropped by seven per cent since mid-March, while in Manitoba a Consumers Coalition has urged rejection of proposed rate increases.
BC Hydro says a prolonged drop in demand could have an impact on future rates, which could potentially go up as the power provider looks to recoup deferred operating costs and financial losses.
In Manitoba, Manitoba Hydro's debt has grown significantly, underscoring the financial risks utilities face during demand shocks.
Fish said the crown corporation still expects there to be increased demand in the long-term. She said construction of the Site C Dam is continuing as planned to support clean-energy generation in the province. There are currently nearly 1,000 workers on-site.
ITER Nuclear Fusion advances tokamak magnetic confinement, heating deuterium-tritium plasma with superconducting magnets, targeting net energy gain, tritium breeding, and steam-turbine power, while complementing laser inertial confinement milestones for grid-scale electricity and 2025 startup goals.
Key Points
ITER Nuclear Fusion is a tokamak project confining D-T plasma with magnets to achieve net energy gain and clean power.
✅ Tokamak magnetic confinement with high-temp superconducting coils
✅ Deuterium-tritium fuel cycle with on-site tritium breeding
✅ Targets net energy gain and grid-scale, low-carbon electricity
It sounds like the stuff of dreams: a virtually limitless source of energy that doesn’t produce greenhouse gases or radioactive waste. That’s the promise of nuclear fusion, often described as the holy grail of clean energy by proponents, which for decades has been nothing more than a fantasy due to insurmountable technical challenges. But things are heating up in what has turned into a race to create what amounts to an artificial sun here on Earth, one that can provide power for our kettles, cars and light bulbs.
Today’s nuclear power plants create electricity through nuclear fission, in which atoms are split, with next-gen nuclear power exploring smaller, cheaper, safer designs that remain distinct from fusion. Nuclear fusion however, involves combining atomic nuclei to release energy. It’s the same reaction that’s taking place at the Sun’s core. But overcoming the natural repulsion between atomic nuclei and maintaining the right conditions for fusion to occur isn’t straightforward. And doing so in a way that produces more energy than the reaction consumes has been beyond the grasp of the finest minds in physics for decades.
But perhaps not for much longer. Some major technical challenges have been overcome in the past few years and governments around the world have been pouring money into fusion power research as part of a broader green industrial revolution under way in several regions. There are also over 20 private ventures in the UK, US, Europe, China and Australia vying to be the first to make fusion energy production a reality.
“People are saying, ‘If it really is the ultimate solution, let’s find out whether it works or not,’” says Dr Tim Luce, head of science and operation at the International Thermonuclear Experimental Reactor (ITER), being built in southeast France. ITER is the biggest throw of the fusion dice yet.
Its $22bn (£15.9bn) build cost is being met by the governments of two-thirds of the world’s population, including the EU, the US, China and Russia, at a time when Europe is losing nuclear power and needs energy, and when it’s fired up in 2025 it’ll be the world’s largest fusion reactor. If it works, ITER will transform fusion power from being the stuff of dreams into a viable energy source.
Constructing a nuclear fusion reactor ITER will be a tokamak reactor – thought to be the best hope for fusion power. Inside a tokamak, a gas, often a hydrogen isotope called deuterium, is subjected to intense heat and pressure, forcing electrons out of the atoms. This creates a plasma – a superheated, ionised gas – that has to be contained by intense magnetic fields.
The containment is vital, as no material on Earth could withstand the intense heat (100,000,000°C and above) that the plasma has to reach so that fusion can begin. It’s close to 10 times the heat at the Sun’s core, and temperatures like that are needed in a tokamak because the gravitational pressure within the Sun can’t be recreated.
When atomic nuclei do start to fuse, vast amounts of energy are released. While the experimental reactors currently in operation release that energy as heat, in a fusion reactor power plant, the heat would be used to produce steam that would drive turbines to generate electricity, even as some envision nuclear beyond electricity for industrial heat and fuels.
Tokamaks aren’t the only fusion reactors being tried. Another type of reactor uses lasers to heat and compress a hydrogen fuel to initiate fusion. In August 2021, one such device at the National Ignition Facility, at the Lawrence Livermore National Laboratory in California, generated 1.35 megajoules of energy. This record-breaking figure brings fusion power a step closer to net energy gain, but most hopes are still pinned on tokamak reactors rather than lasers.
In June 2021, China’s Experimental Advanced Superconducting Tokamak (EAST) reactor maintained a plasma for 101 seconds at 120,000,000°C. Before that, the record was 20 seconds. Ultimately, a fusion reactor would need to sustain the plasma indefinitely – or at least for eight-hour ‘pulses’ during periods of peak electricity demand.
A real game-changer for tokamaks has been the magnets used to produce the magnetic field. “We know how to make magnets that generate a very high magnetic field from copper or other kinds of metal, but you would pay a fortune for the electricity. It wouldn’t be a net energy gain from the plant,” says Luce.
One route for nuclear fusion is to use atoms of deuterium and tritium, both isotopes of hydrogen. They fuse under incredible heat and pressure, and the resulting products release energy as heat
The solution is to use high-temperature, superconducting magnets made from superconducting wire, or ‘tape’, that has no electrical resistance. These magnets can create intense magnetic fields and don’t lose energy as heat.
“High temperature superconductivity has been known about for 35 years. But the manufacturing capability to make tape in the lengths that would be required to make a reasonable fusion coil has just recently been developed,” says Luce. One of ITER’s magnets, the central solenoid, will produce a field of 13 tesla – 280,000 times Earth’s magnetic field.
The inner walls of ITER’s vacuum vessel, where the fusion will occur, will be lined with beryllium, a metal that won’t contaminate the plasma much if they touch. At the bottom is the divertor that will keep the temperature inside the reactor under control.
“The heat load on the divertor can be as large as in a rocket nozzle,” says Luce. “Rocket nozzles work because you can get into orbit within minutes and in space it’s really cold.” In a fusion reactor, a divertor would need to withstand this heat indefinitely and at ITER they’ll be testing one made out of tungsten.
Meanwhile, in the US, the National Spherical Torus Experiment – Upgrade (NSTX-U) fusion reactor will be fired up in the autumn of 2022, while efforts in advanced fission such as a mini-reactor design are also progressing. One of its priorities will be to see whether lining the reactor with lithium helps to keep the plasma stable.
Choosing a fuel Instead of just using deuterium as the fusion fuel, ITER will use deuterium mixed with tritium, another hydrogen isotope. The deuterium-tritium blend offers the best chance of getting significantly more power out than is put in. Proponents of fusion power say one reason the technology is safe is that the fuel needs to be constantly fed into the reactor to keep fusion happening, making a runaway reaction impossible.
Deuterium can be extracted from seawater, so there’s a virtually limitless supply of it. But only 20kg of tritium are thought to exist worldwide, so fusion power plants will have to produce it (ITER will develop technology to ‘breed’ tritium). While some radioactive waste will be produced in a fusion plant, it’ll have a lifetime of around 100 years, rather than the thousands of years from fission.
At the time of writing in September, researchers at the Joint European Torus (JET) fusion reactor in Oxfordshire were due to start their deuterium-tritium fusion reactions. “JET will help ITER prepare a choice of machine parameters to optimise the fusion power,” says Dr Joelle Mailloux, one of the scientific programme leaders at JET. These parameters will include finding the best combination of deuterium and tritium, and establishing how the current is increased in the magnets before fusion starts.
The groundwork laid down at JET should accelerate ITER’s efforts to accomplish net energy gain. ITER will produce ‘first plasma’ in December 2025 and be cranked up to full power over the following decade. Its plasma temperature will reach 150,000,000°C and its target is to produce 500 megawatts of fusion power for every 50 megawatts of input heating power.
“If ITER is successful, it’ll eliminate most, if not all, doubts about the science and liberate money for technology development,” says Luce. That technology development will be demonstration fusion power plants that actually produce electricity, where advanced reactors can build on decades of expertise. “ITER is opening the door and saying, yeah, this works – the science is there.”
Seattle City Light Energy Efficiency Programs help 93,000 residents cut bills with rebates, home energy audits, weatherization, conservation workshops, and sustainability tools, reducing electricity use and greenhouse gas emissions across Seattle communities.

In a noteworthy achievement for both residents and the environment, Seattle City Light has successfully helped more than 93,000 customers reduce their electricity bills through various energy efficiency programs. This initiative not only alleviates financial burdens for many households, amid concerns about pandemic-era shut-offs that heightened energy insecurity, but also aligns with the city’s commitment to sustainability and responsible energy use.
The Drive for Energy Efficiency
Seattle City Light, the city’s publicly owned electric utility, has been at the forefront of promoting energy efficiency among its customers. Recognizing that energy costs can strain household budgets, the utility has developed a range of programs and tracks emerging utility rate designs to help residents lower their energy consumption and, consequently, their bills.
One of the main aspects of this initiative is the emphasis on education and awareness. By providing customers with tools and resources to understand their energy usage, City Light empowers residents to make informed choices that can lead to substantial savings and prepare for power outage events as well.
Key Programs and Services
Seattle City Light offers a variety of programs aimed at reducing energy consumption. Among the most popular are:
Energy Efficiency Rebates: Customers can receive rebates for purchasing energy-efficient appliances, such as refrigerators, washing machines, and HVAC systems. These appliances are designed to consume less electricity than traditional models, resulting in lower energy bills over time.
Home Energy Audits: Free energy audits are available for residential customers. During these audits, trained professionals assess homes for energy efficiency and provide recommendations on improvements. This personalized service allows homeowners to understand specific changes that can lead to savings.
Weatherization Assistance: This program is particularly beneficial for low-income households. By improving insulation, sealing air leaks, and enhancing overall energy efficiency, residents can maintain comfortable indoor temperatures without over-relying on heating and cooling systems.
Community Workshops: Seattle City Light conducts workshops that educate residents about energy conservation strategies. These sessions cover topics such as smart energy use, seasonal tips for reducing consumption, and the benefits of renewable energy sources, highlighting examples of clean energy engagement in other cities.
The Impact on Households
The impact of these initiatives is profound. By assisting over 93,000 customers in lowering their electricity bills, Seattle City Light not only provides immediate financial relief but also encourages a long-term commitment to energy conservation. This collective effort has resulted in significant reductions in overall energy consumption, contributing to a decrease in greenhouse gas emissions—a critical step in the fight against climate change.
Additionally, the programs have been particularly beneficial for low-income households. By targeting these communities, Seattle City Light ensures that the benefits of energy efficiency reach those who need them the most, promoting equity-focused regulation and access to essential resources.
Looking Ahead: Challenges and Opportunities
While the success of these initiatives is commendable, challenges remain. Fluctuating energy prices can still pose difficulties for many households, especially those on fixed incomes, as some utilities explore minimum charges for low-usage customers in their rate structures. Seattle City Light recognizes the need for ongoing support and resources to help residents navigate these financial challenges.
The utility is committed to expanding its programs to reach even more customers in the future. This includes enhancing outreach efforts to ensure that residents are aware of the available resources, even as debates like utility revenue in a free-electricity future shape planning, and potentially forming partnerships with local organizations to broaden the impact of its initiatives.
PG&E Wildfire Blackouts highlight California power shutoffs as high winds and suspected transmission line faults trigger evacuations, CPUC investigations, and grid safety reviews, with utilities weighing risk, compliance, and resilience during Santa Ana conditions.
Key Points
PG&E Wildfire Blackouts are outages during wind-driven fire threats linked to power lines, spurring CPUC investigations.
✅ Wind and line faults suspected amid Lafayette evacuations
✅ CPUC to probe shutoffs, notifications, and compliance
✅ Utilities plan more outages as Santa Ana winds return
Pacific Gas & Electric Co. power lines may have started two wildfires over the weekend in the San Francisco Bay Area, the utility said Monday, even though widespread blackouts were in place to prevent downed lines from starting fires during dangerously windy weather.
The fires described in PG&E reports to state regulators match blazes that destroyed a tennis club and forced evacuations in Lafayette, about 20 miles (32 kilometres) east of San Francisco.
The fires began in a section of town where PG&E had opted to keep the lights on. The sites were not designated as a high fire risk, the company said.
Powerful winds were driving multiple fires across California and forcing power shut-offs intended to prevent blazes, even as electricity prices are soaring across the state as well.
More than 900,000 power customers -- an estimated 2.5 million people -- were in the dark at the height of the latest planned blackout, nearly all of them in PG&E's territory in Northern and central California. By Monday evening a little less than half of those had their service back. But some 1.5 million people in 29 counties will be hit with more shut-offs starting Tuesday because another round of strong winds is expected, a reminder of grid stress during heat waves that test capacity, the utility said.
Southern California Edison had cut off power to 25,000 customers and warned that it was considering disconnecting about 350,000 more as power supply lapses and Santa Ana winds return midweek.
PG&E is under severe financial pressure after its equipment was blamed for a series of destructive wildfires and its 2018 Camp Fire guilty plea compounded liabilities during the past three years. Its stock dropped 24% Monday to close at $3.80 and was down more than 50% since Thursday.
The company reported last week that a transmission tower may have caused a Sonoma County fire that has forced 156,000 people to evacuate.
PG&E told the California Public Utilities Commission that a worker responded to a fire in Lafayette late Sunday afternoon and was told firefighters believed contact between a power line and a communication line may have caused it.
A worker went to another fire about an hour later and saw a fallen pole and transformer. Contra Costa Fire Department personnel on site told the worker they were looking at the transformer as a potential ignition source, a company official wrote.
Separately, the company told regulators that it had failed to notify 23,000 customers, including 500 with medical conditions, before shutting off their power earlier this month during windy weather.
Before a planned blackout, power companies are required to notify customers and take extra care to get in touch with those with medical problems who may not be able to handle extended periods without air conditioning or may need power to run medical devices.
PG&E said some customers had no contact information on file. Others were incorrectly thought to be getting electricity.
After that outage, workers discovered 43 cases of wind-related damage to power lines, transformers and other equipment.
Jennifer Robison, a PG&E spokeswoman, said the company is working with independent living centres to determine how best to serve people with disabilities.
U.S. Rep. Josh Harder, a Democrat from Modesto, said he plans to introduce legislation that would raise PG&E's taxes if it pays bonuses to executives while engaging in blackouts.
The Public Utilities Commission plans to open a formal investigation into the blackouts and the broader climate policy debate surrounding reliability within the next month, allowing regulators to gather evidence and question utility officials. If rules are found to be broken, they can impose fines up to $100,000 per violation per day, said Terrie Prosper, a spokeswoman for the commission.
The commission said Monday it also plans to review the rules governing blackouts, will look to prevent utilities from charging customers when the power is off and will convene experts to find grid improvements that might lessen blackouts during next year's fire season, as debates over rate stability in 2025 continue across PG&E's service area.
The state can't continue experiencing such widespread blackouts, "nor should Californians be subject to the poor execution that PG&E in particular has exhibited," Marybel Batjer, president of the California Public Utilities Commission, said in a statement.
Expanded Hoa Binh Hydropower Plant increases EVN capacity with 480MW turbines, commercial loan financing, grid stability, flood control, and Da River reliability, supported by PECC1 feasibility work and CMSC collaboration on site clearance.
Key Points
A 480MW EVN expansion on the Da River to enhance grid stability, flood control, and seasonal water supply in Vietnam.
✅ 480MW, two turbines, EVN-led financing without guarantees
✅ Improves frequency modulation and national grid stability
✅ Supports flood control and dry-season water supply
The extended Hoa Binh Hydropower Plant, which is expected to break ground in October 2020, is considered the largest power project to be constructed this year, even as Vietnam advances a mega wind project planned for 2025.
Covering an area of 99.2 hectares, the project is invested by Electricity of Vietnam (EVN). Besides, Vietnam Electricity Power Projects Management Board No.1 (EVNPMB1) is the representative of the investor and Power Engineering Consulting JSC 1 (EVNPECC1) is in charge of building the feasibility report for the project. The expanded Hoa Binh Hydro Power Plant has a total investment of VND9.22 trillion ($400.87 million), 30 per cent of which is EVN’s equity and the remaining 70 per cent comes from commercial loans without a government guarantee.
According to the initial plan, EVN will begin the construction of the project in the second quarter of this year and is expected to take the first unit into operation in the third quarter of 2023, a timeline reminiscent of Barakah Unit 1 reaching full power, and the second one in the fourth quarter of the same year.
Chairman of the Committee for Management of State Capital at Enterprises (CMSC) Nguyen Hoang Anh said that in order to start the construction in time, CMSC will co-operate with EVN to work with partners as well as local and foreign banks to mobilise capital, reflecting broader nuclear project milestones across the energy sector.
In addition, EVN will co-operate with Hoa Binh People’s Committee to implement site clearance, remove Ba Cap port and select contractors.
Once completed, the project will contribute to preventing floods in the rainy season and supply water in the dry season. The plant expansion will include two turbines with the total capacity of 480MW, similar in scale to the 525-MW hydropower station China is building on a Yangtze tributary, and electricity output of about 488.3 million kWh per year.
In addition, it will help improve frequency modulation capability and stabilise the frequency of the national electricity system through approaches like pumped storage capacity, and reduce the working intensity of available turbines of the plant, thus prolonging the life of the equipment and saving maintenance and repair costs.
Built in the Da River basin in the northern mountainous province of Hoa Binh, at the time of its conception in 1979, Hoa Binh was the largest hydropower plant in Southeast Asia, while projects such as China’s Lawa hydropower station now dwarf earlier benchmarks.
The construction was supported by the Soviet Union all the way through, designing, supplying equipment, supervising, and helping it go on stream. Construction began in November 1979 and was completed 15 years later in December 1994, when it was officially commissioned, similar to two new BC generating stations recently brought online.
