Leningrad II VVER-1200 Reactor Vessel assembly completed in Sosnovy Bor, with Rosenergoatom preparing for first criticality, hydraulic tests, and physical startup checks of neutron physics, control systems, and passive heat removal safety.

Key Points

Core vessel for Leningrad II Unit 1, completed, sealed, and prepared for hydraulic tests ahead of first criticality.

✅ Hydraulic tests to verify circuit integrity and equipment density

✅ Physical tests to refine neutron-physics of initial fuel loading

✅ Passive heat removal system testing completed; fuel loading began

Rosenergoatom has completed the assembly of the reactor vessel for unit 1 of the Leningrad Phase II nuclear power plant, which is in Sosnovy Bor in western Russia, even as it develops power lines to reactivate the Zaporizhzhia plant in a separate project. The nuclear power plant operator subsidiary of state nuclear corporation Rosatom said yesterday the VVER-1200 is now being prepared for first criticality this month.

Alexander Belyaev, chief engineer of Leningrad NPP, said in the company statement, noting industry-wide nuclear project milestones this year: "The reactor is fully assembled, sealed and ready for hydraulic tests of the first and second circuits, during which we will once again check the equipment of the reactor installation, and finally confirm its density. After that, it will be possible to start the reactor at the minimum controlled power level."

Belyaev said this preparatory phase "envisages a whole series of physical tests that will make it possible to refine the neutron-physical characteristics of the first fuel loading of the nuclear reactor, as well as prove the reliability of the entire control and safety system (in line with the US NRC's final safety evaluation for the NuScale SMR) of the reactor installation".

The existing Leningrad plant site has four operating RMBK-1000 units, while Leningrad II will have four VVER-1200 units, as projects like the Georgia nuclear expansion continue to take shape globally. Testing of the passive heat removal system of unit 1 of Leningrad II was completed in late August and fuel loading began in December, while a new U.S. reactor startup underscored the broader resurgence.

Zambia Mining Electricity Tariff Agreement signals a shift to a 9.33 cents/kWh flat rate for mining companies, as Zesco and the ERB steer power pricing talks, with backdating, copper output, and tariffs in focus.

Key Points

A policy to set a 9.33 cents/kWh flat rate for mines, with Zesco backdating terms still under negotiation.

✅ 9.33 cents/kWh flat tariff accepted by most mining houses

✅ Talks involve Zesco, ERB, First Quantum, Glencore, Vale, Vedanta

✅ Backdating to January remains under negotiation

Zambia is close to reaching an agreement with mining companies over its plans to increase electricity prices, in line with recent increases in Hong Kong seen elsewhere, Finance Minister Felix Mutati reports.

The government last month proposed introducing a flat tariff of 9.30 U.S. cents/kilowatt hour (kWh) backdated to January for mining companies, instead of individually negotiated rates that have averaged 6 U.S. cents/kWh, a structure echoing Manitoba's planned 2.5% yearly hikes over three years, but mining companies opposed the plan.

A team headed by the minister of energy was due to hold talks with mining companies this week, including First Quantum Minerals,.

"We have concluded with all the mining houses except for one. They have accepted our proposal to actually pay 9.33 cents/kwh," Mutati told Reuters in a move comparable to BC Hydro's 3.75% rate plan over two years.

However, an agreement has not yet been reached on backdating the higher tariffs to January as proposed by power firm Zesco Ltd, a point comparable to issues outlined in Nunavut's electricity price hike analysis, he said.

"It is part of the negotiations but ideally that is what the government is considering," Mutati said.

Other mining companies operating in Zambia, Africa's No. 2 copper producer, include Glencore of Switzerland, Brazil's Vale and London-listed Vedanta Resources .

Last week Zambia's Energy Regulation Board (ERB) approved a 75 percent increase in the price of electricity for retail customers, whereas utilities such as BC Hydro's $2 per month proposal in Canada have pursued more gradual adjustments.

Three Mile Island closure highlights Exelon's nuclear plant losses as cheap natural gas, grid auctions, and renewable energy credits undercut profitability in Pennsylvania, prompting bailout debates over subsidies, reliability, carbon emissions, and local jobs.

Key Points

The Three Mile Island closure is Exelon's plan to shut the plant after gas losses, failed grid bids, and no state aid.

✅ Cheap natural gas undercuts nuclear profitability

✅ Plant missed capacity market awards in grid auctions

✅ Exelon seeks subsidies; Pennsylvania debates costs

Cheap natural gas could do what the worst commercial nuclear power accident in U.S. history could not: put Three Mile Island out of business.

Three Mile Island’s owner, Exelon Corp., announced Tuesday that the plant, now at the center of an energy debate over whether to let struggling nuclear plants close or save them, will close in 2019 unless the state of Pennsylvania comes to its financial rescue.

Nuclear power plants around the U.S. have been struggling in recent years, even as nuclear generation costs hit a ten-year low, to compete with generating stations that burn plentiful and inexpensive natural gas to produce electricity.

The Chicago-based energy company’s announcement came after what it called more than five years of losses at the single-reactor plant and Three Mile Island’s recent failure to be selected as a guaranteed supplier of power to the regional electric grid.

Exelon wants Pennsylvania to give nuclear power the kind of preferential treatment and premium payments that are extended to renewable forms of energy, such as wind and solar. It has not said how much it wants.

Pennsylvania Gov. Tom Wolf has made no commitment to a bailout. In a statement Tuesday, Wolf said he is concerned about layoffs at Three Mile Island and open to discussions about the future of nuclear power in the state. Exelon employs 675 people at the plant, whose license does not expire until 2034.

Nuclear bailouts have won approval in Illinois and New York, but the potential for higher utility bills in Pennsylvania is generating resistance from rival energy companies, manufacturers and consumer advocates.

The control room seen at the Three Mile Island nuclear power plant. The site has struggled to compete in an electricity market booming with inexpensive gas.

David Hughes, president of the Pittsburgh-based consumer group Citizen Power, said the notion that nuclear power is clean energy, as the industry argues, is laughable.

“It’s a myth, and they’re trying any way they can to get more money out of ratepayers,” he said.

In addition to contending that nuclear power can help fight climate change and enable net-zero emissions better than gas or coal, Exelon and other energy companies have argued that their plants are big employers and sources of tax revenue.

“Like New York and Illinois before it, the commonwealth has an opportunity to take a leadership role by implementing a policy solution to preserve its nuclear energy facilities and the clean, reliable energy and good-paying jobs they provide,” Chris Crane, Exelon president and CEO, said in a statement.

Around the U.S., nuclear plants have been hammered by the natural gas boom.

In December, Illinois approved $235 million a year for Exelon to prop up nuclear plants in the Quad Cities and Clinton, six months after the company threatened to shut them down.

FirstEnergy Corp. has said it could decide next year to sell or close its three nuclear plants — Davis-Besse and Perry in Ohio and Beaver Valley in Pennsylvania. PSEG of New Jersey, which owns all or parts of four nuclear plants, has said it won’t operate ones that are long-term money losers.

Built during a golden age for nuclear power, Three Mile Island’s Unit 1 went online in 1974 and Unit 2 in 1978, coughing steam into the air above its sliver of land in the Susquehanna River, about 10 miles from Harrisburg.

In March 1979, equipment failure and operator errors led to a partial core meltdown of Unit 2, leading to several days of fear and prompting 144,000 people to flee their homes amid conflicting or ill-informed information from utility and government officials.

Scientists worried at one point that a hydrogen bubble forming inside the reactor would explode with catastrophic consequences.

Experts have come to no firm conclusion about the health effects or the amount of radiation released, though government scientists have said the maximum individual dosage was not enough to cause health problems.

Regardless, the accident badly undermined support for nuclear power. No nuclear plant that was proposed after the accident has been successfully completed and put into operation in the U.S.

The damaged reactor has been mothballed, but the other reactor is still in use. Exelon says the operating costs for just the one unit are high, further straining Three Mile Island’s financial health.

Pennsylvania is the nation’s No. 2 nuclear power state, after Illinois.

Closing Three Mile Island would have little or no effect on electricity bills, analysts say. But the power may be replaced by electricity generated by carbon-emitting fuels such as coal or gas.

Because of the flood of natural gas on the market, a lot of it from the Northeast’s Marcellus Shale formation, dozens of new gas-fired plants are coming online or planned. At the same times, states are putting more emphasis on renewable energy and efficiency.

Alberta Renewable Energy Auction invites bids as AESO adds wind and solar capacity, targeting 5,000 MW by 2030, with 400 MW online by 2019 to replace coal, stabilize prices, and cut greenhouse gas emissions.

Key Points

A program to procure wind and solar for Alberta’s grid, replacing coal and scaling to 5,000 MW by 2030.

✅ 400 MW online by 2019 to backfill retiring coal units

✅ Timed additions to avoid price distortion on the grid

✅ Targets 5,000 MW of renewables by 2030

The operator of Alberta's electricity grid will start taking bids at the end of this month from companies interested in generating and selling renewable energy in the province.

The provincial government wants to add 5,000 megawatts of renewable electricity, supporting new jobs across the province by 2030.

The renewables, including wind power and solar power, will replace coal-fired power plants, which will be shutting down as part of the province's strategy to lower greenhouse gas emissions.

Energy Minister Marg McCuaig-Boyd announced Friday the first competition will be for 400 megawatts, which is enough to power about 170,000 houses.

"We're known as the energy hub of Canada, and make no mistake, green energy is a big part of that," she said.

Mike Deising with the Alberta Electric System Operator (AESO) says the new green power has to be developed gradually.

"We don't want to put on too much generation because what we're going to see is, if we have too much generation all at once, we're going to drive down the market price and it's going to distort the electricity market that we have," he said.

Deising says from their perspective as the grid operator, they want to make sure the addition of new capacity is timed with when they are losing capacity.

AESO wants the 400 megawatts of new green power including solar generation to go onto the grid by the end of 2019 to replace electricity from coal-fired plants that will start shutting down by late 2020.

Peter Sutherland Sr. Generating Station delivers 28 MW hydroelectric, renewable energy in Ontario via an Indigenous partnership, on-budget and ahead of schedule, supplying the provincial grid near the Abitibi River at New Post Creek.

Key Points

An OPG-Indigenous hydropower plant generating 28 MW in northern Ontario, feeding the provincial grid from New Post Creek.

✅ 28 MW hydropower on Abitibi River at New Post Creek.

✅ OPG and Taykwa Tagamou Nation partnership, on-budget and ahead of schedule.

✅ $300 million project delivers jobs, skills, and long-term revenue to community.

Ontario Power Generation, which has also partnered on new nuclear technology with TVA, says a new hydroelectric plant in the northern part of the province is now online, and the First Nation it has partnered with stands to benefit.

In a written release issued Friday, OPG announced the completion of the Peter Sutherland Sr. Generating Station on New Post Creek. The project is a partnership between the provincial power company and Coral Rapids Power, an Indigenous-owned company of the Taykwa Tagamou Nation, near Cochrane.

"This project has gone well due to the relationship we've built on a foundation of respect and trust," Coral Rapids President Wayne Ross was quoted as saying in the OPG release.

"There have been many benefits for our community including good paying jobs, transferable skills and a long term revenue stream."

The generating station, which is located about 80 kilometres north of Smooth Rock Falls, near where New Post Creek meets the Abitibi River, is named after a respected elder of the Taykwa Tagamou Nation. It generates 28 megawatts of power for the provincial grid, according to OPG, complementing modernization at the Niagara Falls powerhouse upgrade as well.

The project was finished ahead of schedule and on-budget, OPG said, as other Ontario initiatives like a pumped storage project advance.

According to the announcement and recent financial results, the project cost around $300 million.

SaskPower Geothermal Power aims to deliver renewable baseload energy in Saskatchewan, complementing wind and solar. With DEEP's 5 MW pilot near Estevan tapping aquifers, it supports grid reliability alongside LED streetlights and flare gas.

Key Points

SaskPower Geothermal Power is a baseload plan using DEEP's aquifers to deliver zero-emission power in Saskatchewan.

✅ 5 MW DEEP pilot near Estevan targets hot sedimentary aquifers

✅ Provides 24/7 renewable baseload, complementing wind and solar

✅ Higher upfront costs and timelines challenge rapid deployment

It would be a first for Saskatchewan and Canada.

SaskPower‘s efforts to double renewable electricity by 2030 could potentially include geothermal power stations.

 Regina and Saskatoon areas were selected to provide a range of settings to test the new LED streetlights SaskPower is piloting. SaskPower pilot project converting streetlights to LED

“If projections hold true, we’re going to need to find over 2,000 megawatts of renewable power,” Kirsten Marcia, president and CEO of Deep Earth Energy Production (DEEP), said.

“Geothermal is not the only solution here, but we hope to have a very significant place at the table.”

With a power purchase agreement with SaskPower signed in May, and ongoing initiatives such as purchasing power from Flying Dust First Nation to diversify supply, DEEP hopes to build a five megawatt, zero emission power plant near Estevan, where subterranean water is the warmest in Saskatchewan.

Typically, geothermal operations use the water for heat, as in Manitoba's geothermal homes initiative where thousands of residences would be converted; however DEEP’s plant will pass water through an exchanger to create steam, which will drive a turbine and generate energy.

“You think of our potash resources, our oil and gas resources, and at the very bottom of those sedimentary units is thick, 150 metre deep aquifer,” Marcia said. “We could drill it here in Saskatoon, but it’s too shallow to be hot enough, and the same aquifer continues to deepen as we go towards the United States, it’s about 3.4 kilometers in depth, so that’s what gives it the heat.”

But is investment in geothermal power generation worth it for the province? Experts say they’re cautiously optimistic, but initial costs may drive away potential interest, which is why SaskPower is also planning to buy more electricity from Manitoba Hydro as a complementary measure.

“The payback period is going to be much longer,” said Grant Ferguson, an associate professor of geological engineering at the University of Saskatchewan. “So we’re going to run into problems with risk and financing and these sorts of things that might not be in play with something like a wind or solar project.”

Time is also a factor.

Each unit is expected to generate between five and 10 megawatts of power; multiple unites would be required to generate the amount of power needed in Saskatchewan. Nearly a decade of work has gone into DEEP’s first station.

“If we’re looking towards 2030 and we’re taking 10 years for one, then it’s going to take a while to pull all this off,” Ferguson said.

“Maybe if it's on the space of two or three years then we can build these things up.”

The benefit geothermal electricity has over solar and wind generated power? Electricity is consistently being generated, even during record power demand events in Saskatchewan.

“Ideally, this becomes a baseload power supply,” Marcia said, “so unlike wind and solar, which provide an intermittent power supply, geothermal is the only renewable that provides power 24 hours a day, seven days a week.”

DEEP’s first plant is expected to be built in two years. It’s expected the aquifer will be able to support a capacity of roughly 200 megawatts.
