Five summers and two sweeping national energy laws ago, a few overgrown trees tripped power lines in Ohio, cascading into a blackout for much of the northeastern U.S. and Canada. Yet the nation's electric grid is still in drastic need of an overhaul.

The problems abound: increasing demand for electricity consistently strains the aging network. When planning system upgrades, power companies find themselves burdened by regulatory details and local opposition. Deregulation of the utility industry in the past two decades has fractured investment in transmission lines.

There's help on the way. Start-ups, big utilities and government have unleashed a wave of investment to make the electric grid smarter and more efficient, in spite of (and perhaps because of) underinvestment in transmission. The reason? Potentially enormous profits associated with getting more out of the network that's already in place.

"More generators just congest the system," says Roland Schoettle, founder and chief executive of Optimal Technologies International, a Raleigh, N.C.-based company that is scrambling to get in on the energy efficiency game.

In May the company commercially unveiled technology to measure the performance throughout the power grid, making congestion points more transparent. Optimal says its product could eradicate blackouts. That remains to be seen, though the company received $25 million in funding from Goldman Sachs, and California's grid operator has already successfully tested the system.

Of course, the "grid" is not actually a single web of infrastructure spanning the country, and efficiency gains are localized, often at the utility level. The grid itself is a network of about 10,000 power plants and power lines that runs within three different interconnections - in the West, the East and in Texas. Distribution of electricity is the responsibility of local utilities.

The big coup for start-ups, obviously, lies in turning utilities into customers. A good example: Virginia-based GridPoint, which recently announced partnerships with Duke Energy and Xcel Energy. Duke and GridPoint in March tested a technology that allows utilities to reduce stress on the grid caused by plug-in hybrid electric vehicles. Two months later, the start-up said Xcel will use GridPoint technology as it builds the nation's first "SmartGridCity" in Boulder, Colo.

In fact, the SmartGridCity is a massive energy efficiency project unto itself and a good example of how major utilities are getting in on the action. Think of it as a "Tomorrowland" for electricity, a prototype community that allows customers to determine when and how they'll use energy. Scheduled to be completed in 2009, it will include advanced meters, a network upgrade and the ability for local power sources to link up to the grid.

Known as "distributed generation," this localized power production is a key factor - and possibly the Achilles' heel - in the evolution of the smart grid. The idea behind distributed generation is to produce electricity near homes and businesses (usually from natural gas, small wind turbines or solar energy systems), thus alleviating the strain on power lines. In some cases, distributed power connections can sell energy back into the grid.

One quickly growing component of the distributed generation world is solar energy. Although it now provides less than 0.1% of the electricity generated in the U.S., solar power could account for 10% of the nation's power needs by 2025, according to a new study by the research firm Clean Edge. Already, companies such as Google and eBay are installing solar panels on their offices to reduce their reliance on the grid for power.

But here's the rub: Not all distributed generation is created equally. Local power sources frequently don't have the same voltage standards as electricity that comes from a centralized source, such as a coal-fired power plant. If a distributed generator goes out of service, it could prove a weak spot in the grid if it has no backup. The group that monitors grid reliability for federal regulators, the North American Electric Reliability Corp., doesn't have jurisdiction over local power lines. That's up to the utilities.

"If distributed generation is not integrated properly, it could have negative impacts," says Steve Hauser, president of the GridWise Alliance, a group pushing for a smarter grid, and a vice president at GridPoint.

So far, there hasn't been a major problem. And it looks as if Uncle Sam is keen to help the smart grid develop so catastrophe doesn't occur. The energy law passed by Congress last December calls for the U.S. Department of Energy to create a program to help cover the cost of smart-grid investments. It also requires the agency to report to lawmakers annually on the grid's evolution.

But some of the most meaningful action will probably come at the local level. Earlier this year, the Federal Energy Regulatory Commission announced that it's starting a "collaborative dialogue" with state regulators to begin the transition to a smarter grid.

NTPC bags order to supply 300 MW electricity to Bangladesh

NTPC Bangladesh Power Supply Tender sees NVVN win 300 MW, long-term cross-border electricity trade to BPDB, enabled by 500 MW HVDC interconnection; rivals included Adani, PTC, and Sembcorp in the competitive bidding process.

 

Key Points

It is NTPC's NVVN win to supply 300 MW to Bangladesh's BPDB for 15 years via a 500 MW HVDC link.

✅ NVVN selected as L1 for short and long-term supply

✅ 300 MW to BPDB; delivery via India-Bangladesh HVDC link

✅ Competing bidders: Adani, PTC, Sembcorp

 

NTPC, India’s biggest electricity producer in a nation that is now the third-largest electricity producer globally, on Tuesday said it has won a tender to supply 300 megawatts (MW) of electricity to Bangladesh for 15 years.

Bangladesh Power Development Board (BPDP), in a market where Bangladesh's nuclear power is expanding with IAEA assistance, had invited tenders for supply of 500 MW power from India for short term (1 June, 2018 to 31 December, 2019) and long term (1 January, 2020 to 31 May, 2033). NTPC Vidyut Vyapar Nigam (NVVN), Adani Group, PTC and Singapore-bases Sembcorp submitted bids by the scheduled date of 11 January.

Financial bid was opened on 11 February, the company said in a statement, amid rising electricity prices domestically. “NVVN, wholly-owned subsidiary of NTPC Limited, emerged as successful bidder (L1), both in short term and long term for 300 MW power,” it said.

Without giving details of the rate at which power will be supplied, NTPC said supply of electricity is likely to commence from June 2018 after commissioning of 500 MW HVDC inter-connection project between India and Bangladesh, and as the government advances nuclear power initiatives to bolster capacity in the sector. India currently exports approximately 600 MW electricity to Bangladesh even as authorities weigh coal rationing measures to meet surging demand domestically.

WY Utility's First Wind Farm Faces Replacement

Foote Creek I Wind Farm Repowering upgrades Wyoming turbines with new nacelles, towers, and blades, cutting 68 units to 12 while sustaining 41.6 MW, under PacifiCorp and Rocky Mountain Power's Energy Vision 2020 plan.

 

Key Points

Replacement at Foote Creek Rim I, cutting to 12 turbines while sustaining about 41.6 MW using modern 2-4.2 MW units.

✅ 12 turbines replace 68, output steady near 41.6 MW

✅ New nacelles, towers, blades; taller 500 ft turbines

✅ Part of PacifiCorp Energy Vision 2020 and Gateway West

 

A Wyoming utility company has filed a permit to replace its first wind farm—originally commissioned in 1998, composed of over 65 turbines—amid new gas capacity competing with nuclear in Ohio, located at Foote Creek Rim I. The replacement would downsize the number of turbines to 12, which would still generate roughly the same energy output.

According to the Star Tribune, PacifiCorp’s new installation would involve new nacelles, new towers and new blades. The permit was filed with Carbon County.

 

New WY Wind Farm

The replacement wind turbines will stand more than twice as tall as the old: Those currently installed stand 200 feet tall, whereas their replacements will tower closer to 500 feet. Though this move is part of the company’s overall plan to expand its state wind fleet as some utilities respond to declining coal returns in the Midwest, the work going into the Foote Creek site is somewhat special, noted David Eskelsen, spokesperson for Rocky Mountain Power, the western arm of PacifiCorp.

“Foote Creek I repowering is somewhat different from the repowering projects announced in the (Energy Vision) 2020 initiative,” he said. “Foote Creek is a complete replacement of the existing 68 foundations, towers, turbine nacelles and rotors (blades).”

Currently, the turbines at Foote Creek have 600 kilowatts capacity each; the replacements’ maximum production ranges from 2 megawatts to 4.2 megawatts each, with the total output remaining steady at 41.4 megawatts, a scale similar to a 30-megawatt wind expansion in Eastern Kings, though there will be a slight capacity increase to 41.6 megawatts, according to the Star Tribune.

As part of the wind farm repowering initiative, PacifiCorp is to become full owner and operator of the Foote Creek site. When the farm was originally built, an Oregon-based water and electric board was 21 percent owner; 37 percent of the project’s output was tied into a contract with the Bonneville Power Administration.

Otherwise, PacifiCorp is moving to further expand its state wind fleet in line with initiatives like doubling renewable electricity by 2030 in Saskatchewan, with the addition of three new wind farms—to be located in Carbon, Albany and Converse counties—which may add up to 1,150 megawatts of power.

According to PacifiCorp, the company has more than 1,000 megawatts of owned wind generation capability, along with long-term purchase agreements for more than 600 megawatts from other wind farms owned by other entities. Energy Vision 2020 refers to a $3.5 billion investment and company move that is looking to upgrade the company's existing wind fleet with newer technology, adding 1,150 megawatts of new wind resources by 2020 and a a new 140-mile Gateway West transmission segment in Wyoming, comparable to a transmission project in Missouri just energized.

Opinion: Cleaning Up Ontario's Hydro Mess - Ford government needs to scrap the Fair Hydro Plan and review all options

Ontario Hydro Crisis highlights soaring electricity rates, costly subsidies, nuclear refurbishments, and stalled renewables in Ontario. Policy missteps, weak planning, and rising natural gas emissions burden ratepayers while energy efficiency and storage remain underused.

 

Key Points

High power costs and subsidies from policy errors, nuclear refurbishments, stalled efficiency and renewables in Ontario.

✅ $5.6B yearly subsidy masks electricity rates and deficits

✅ Nuclear refurbishments embed rising costs for decades

✅ Efficiency, storage, and DERs stalled amid weak planning

 

By Mark Winfield

While the troubled Site C and Muskrat Falls hydroelectric dam projects in B.C. and Newfoundland and Labrador have drawn a great deal of national attention over the past few months, Ontario has quietly been having a hydro crisis of its own.

One of the central promises in the 2018 platform of the Ontario Progressive Conservative party was to “clean up the hydro mess,” and then-PC leader Doug Ford vowed to fire Hydro One's leadership as part of that effort. There certainly is a mess, with the costs of subsidies taken from general provincial revenues to artificially lower hydro rates nearing $7 billion annually. That is a level approaching the province’s total pre-COVID-19 annual deficit. After only two years, that will also exceed total expected cost overruns of the Site C and Muskrat Falls projects, currently estimated at $12 billion ($6 billion each).

There is no doubt that Doug Ford’s government inherited a significant mess around the province’s electricity system from the previous Liberal governments of former premiers Dalton McGuinty and Kathleen Wynne. But the Ford government has also demonstrated a remarkable capacity for undoing the things its predecessors had managed to get right while doubling down on their mistakes.

The Liberals did have some significant achievements. Most notably: coal-fired electricity generation, which constituted 25 per cent of the province’s electricity supply in the early 2000s, was phased out in 2014. The phaseout dramatically improved air quality in the province. There was also a significant growth in renewable energy production. From  virtually zero in 2003, the province installed 4,500 MW of wind-powered generation, and 450 MW of solar photovoltaic by 2018, a total capacity more than double that of the Sir Adam Beck Generating Stations at Niagara Falls.

At the same time, public concerns over rising hydro rates flowing from a major reconstruction of the province’s electricity system from 2003 onwards became a central political issue in the province. But rather than reconsider the role of the key drivers of the continuing rate increases – namely the massively expensive and risky refurbishments of the Darlington and Bruce nuclear facilities, the Liberals adopted a financially ruinous Fair Hydro Plan. The central feature of the 2017 plan was a short-term 25 per cent reduction in hydro rates, financed by removing the provincial portion of the HST from hydro bills, and by extending the amortization period for capital projects within the system. The total cost of the plan in terms of lost revenues and financing costs has been estimated in excess of $40 billion over 29 years, with the burden largely falling on future ratepayers and taxpayers.


Decision-making around the electricity system became deeply politicized, and a secret cabinet forecast of soaring prices intensified public debate across Ontario. Legislation adopted by the Wynne government in 2016 eliminated the requirement for the development of system plans to be subject to any form of meaningful regulatory oversight or review. Instead, the system was guided through directives from the provincial cabinet. Major investments like the Darlington and Bruce refurbishments proceeded without meaningful, public, external reviews of their feasibility, costs or alternatives.

The Ford government proceeded to add more layers to these troubles. The province’s relatively comprehensive framework for energy efficiency was effectively dismantled in March, 2019, with little meaningful replacement. That was despite strong evidence that energy efficiency offered the most cost-effective strategy for reducing greenhouse gas emissions and electricity costs.

The Ford government basically retained the Fair Hydro Plan and promised further rate reductions, later tabling legislation to lower electricity rates as well. To its credit, the government did take steps to clarify real costs of the plan. Last year, these were revealed to amount to a de facto $5.6 billion-per-year subsidy coming from general revenues, and rising. That constituted the major portion of the province’s $7.4 billion pre-COVID-19 deficit. The financial hole was deepened further through November’s financial statement, with the addition of a further $1.3 billion subsidy to commercial and industrial consumers. The numbers can only get worse as the costs of the Darlington and Bruce refurbishments become embedded more fully into electricity rates.

The government also quietly dispensed with the last public vestige of an energy planning framework, relieving itself of the requirement to produce a Long-Term Energy Plan every three years. The next plan would normally have been due next month, in February.

Even the gains from the 2014 phaseout of coal-fired electricity are at risk. Major increases are projected in emissions of greenhouse gases, smog-causing nitrogen oxides and particulate matter from natural gas-fired power plants as the plants are run to cover electricity needs during the Bruce and Darlington refurbishments over the next decade. These developments could erode as much as 40 per cent of the improvements in air quality and greenhouse gas emission gained through the coal phaseout.

The province’s activities around renewable energy, energy storage and distributed energy resources are at a standstill, with exception of a few experimental “sandbox” projects, while other jurisdictions face profound electricity-sector change and adapt. Globally, these technologies are seen as the leading edge of energy-system development and decarbonization. Ontario seems to have chosen to make itself an energy innovation wasteland instead.

The overall result is a system with little or no space for innovation that is embedding ever-higher costs while trying to disguise those costs at enormous expense to the provincial treasury and still failing to provide effective relief to low-income electricity consumers.

The decline in electricity demand associated with the COVID-19 pandemic, along with the introduction of a temporary recovery rate for electricity, gives the province an opportunity to step back and consider its next steps with the electricity system. A phaseout of the Fair Hydro Plan electricity-rate reduction and its replacement with a more cost-effective strategy of targeted relief aimed at those most heavily burdened by rising hydro rates, particularly rural and low-income consumers, as reconnection efforts for nonpayment have underscored the hardship faced by many households, would be a good place to start.

Next, the province needs to conduct a comprehensive, public review of electricity options available to it, including additional renewables – the costs of which have fallen dramatically over the past decade – distributed energy resources, hydro imports from Quebec and energy efficiency before proceeding with further nuclear refurbishments.

In the longer term, a transparent, evidence-based process for electricity system planning needs to be established – one that is subject to substantive public and regulatory oversight and review. Finally, the province needs to establish a new organization to be called Energy Efficiency Ontario to revive its efforts around energy efficiency, developing a comprehensive energy-efficiency strategy for the province, covering electricity and natural gas use, and addressing the needs of marginalized communities.

Without these kinds of steps, the province seems destined to continue to lurch from contradictory decision after contradictory decision as the economic and environmental costs of the system’s existing trajectory continue to rise.

A new material made from carbon nanotubes can generate electricity by scavenging energy from its environment

Carbon Nanotube Solvent Electricity enables wire-free electrochemistry as organic solvents like acetonitrile pull electrons, powering alcohol oxidation and packed bed reactors, energy harvesting, and micro- and nanoscale robots via redox-driven current.

 

Key Points

Solvent-driven electron extraction from carbon nanotube particles generates current for electrochemistry.

✅ 0.7 V per particle via solvent-induced electron flow

✅ Packed bed reactors drive alcohol oxidation without wires

✅ Scalable for micro- and nanoscale robots; energy harvesting

 

MIT engineers have discovered a new way of generating electricity, alongside advances in renewable power at night that broaden what's possible, using tiny carbon particles that can create a current simply by interacting with liquid surrounding them.

The liquid, an organic solvent, draws electrons out of the particles, generating a current, unlike devices based on a cheap thermoelectric material that rely on heat, that could be used to drive chemical reactions or to power micro- or nanoscale robots, the researchers say.

"This mechanism is new, and this way of generating energy is completely new," says Michael Strano, the Carbon P. Dubbs Professor of Chemical Engineering at MIT. "This technology is intriguing because all you have to do is flow a solvent through a bed of these particles. This allows you to do electrochemistry, but with no wires."

In a new study describing this phenomenon, the researchers showed that they could use this electric current to drive a reaction known as alcohol oxidation—an organic chemical reaction that is important in the chemical industry.

Strano is the senior author of the paper, which appears today in Nature Communications. The lead authors of the study are MIT graduate student Albert Tianxiang Liu and former MIT researcher Yuichiro Kunai. Other authors include former graduate student Anton Cottrill, postdocs Amir Kaplan and Hyunah Kim, graduate student Ge Zhang, and recent MIT graduates Rafid Mollah and Yannick Eatmon.

Unique properties
The new discovery grew out of Strano's research on carbon nanotubes—hollow tubes made of a lattice of carbon atoms, which have unique electrical properties. In 2010, Strano demonstrated, for the first time, that carbon nanotubes can generate "thermopower waves." When a carbon nanotube is coated with layer of fuel, moving pulses of heat, or thermopower waves, travel along the tube, creating an electrical current that exemplifies turning thermal energy into electricity in nanoscale systems.

That work led Strano and his students to uncover a related feature of carbon nanotubes. They found that when part of a nanotube is coated with a Teflon-like polymer, it creates an asymmetry, distinct from conventional thermoelectric materials approaches, that makes it possible for electrons to flow from the coated to the uncoated part of the tube, generating an electrical current. Those electrons can be drawn out by submerging the particles in a solvent that is hungry for electrons.

To harness this special capability, the researchers created electricity-generating particles by grinding up carbon nanotubes and forming them into a sheet of paper-like material. One side of each sheet was coated with a Teflon-like polymer, and the researchers then cut out small particles, which can be any shape or size. For this study, they made particles that were 250 microns by 250 microns.

When these particles are submerged in an organic solvent such as acetonitrile, the solvent adheres to the uncoated surface of the particles and begins pulling electrons out of them.

"The solvent takes electrons away, and the system tries to equilibrate by moving electrons," Strano says. "There's no sophisticated battery chemistry inside. It's just a particle and you put it into solvent and it starts generating an electric field."

Particle power
The current version of the particles can generate about 0.7 volts of electricity per particle. In this study, the researchers also showed that they can form arrays of hundreds of particles in a small test tube. This "packed bed" reactor, unlike thin-film waste-heat harvesters for electronics, generates enough energy to power a chemical reaction called an alcohol oxidation, in which an alcohol is converted to an aldehyde or a ketone. Usually, this reaction is not performed using electrochemistry because it would require too much external current.

"Because the packed bed reactor is compact, it has more flexibility in terms of applications than a large electrochemical reactor," Zhang says. "The particles can be made very small, and they don't require any external wires in order to drive the electrochemical reaction."

In future work, Strano hopes to use this kind of energy generation to build polymers using only carbon dioxide as a starting material. In a related project, he has already created polymers that can regenerate themselves using carbon dioxide as a building material, in a process powered by solar energy and informed by devices that generate electricity at night as a complement. This work is inspired by carbon fixation, the set of chemical reactions that plants use to build sugars from carbon dioxide, using energy from the sun.

In the longer term, this approach could also be used to power micro- or nanoscale robots. Strano's lab has already begun building robots at that scale, which could one day be used as diagnostic or environmental sensors. The idea of being able to scavenge energy from the environment, including approaches that produce electricity 'out of thin air' in ambient conditions, to power these kinds of robots is appealing, he says.

"It means you don't have to put the energy storage on board," he says. "What we like about this mechanism is that you can take the energy, at least in part, from the environment."

Renewable energy now cheapest option for new electricity in most of the world: Report

Renewable Energy Cost Trends highlight IRENA data showing solar and wind undercut coal, as utility-scale projects drive lower levelized electricity costs worldwide, with the Middle East and UAE advancing mega solar parks.

 

Key Points

They track how solar and wind undercut new fossil fuels as utility-scale costs drop and investment accelerates.

✅ IRENA reports renewables cheapest for new installations

✅ Solar and wind LCOE fell sharply since 2010

✅ Middle East and UAE scale mega utility projects

 

Renewable energy is now the cheapest option for new electricity installation in most of the world, a report from the International Renewable Energy Agency (IRENA) on Tuesday said.

Renewable power projects have undercut traditional coal fuel plants, with solar and wind power costs in particular falling as record-breaking growth continues worldwide.

“Installing new renewables increasingly costs less than the cheapest fossil fuels. With or without the health and economic crisis, dirty coal plants were overdue to be consigned to the past, said Francesco La Camera, director-general of IRENA said in the report.

In 2019, renewables accounted for around 72 percent of all new capacity added worldwide, IRENA said, following a 2016 record year that highlighted the momentum, with lowering costs and technological improvements in solar and wind power helping this dynamic. For solar energy, IRENA notes that the cost for electricity from utility-scale plants fell by 82 percent in the decade between 2010 and 2019, as China's solar PV growth underscored in 2016.

“More than half of the renewable capacity added in 2019 achieved lower electricity costs than new coal, while new solar and wind projects are also undercutting the cheapest and least sustainable of existing coal-fired plants,” Camera added.

Costs for solar and wind power also fell year-on-year by 13 and 9 percent, respectively, with offshore wind costs showing steep declines as well. In 2019, more than half of all newly commissioned utility-scale renewable power plants provided electricity cheaper than the lowest cost of a new fossil fuel plant.

The Middle East

In mid-May, a report by UK-based law firm Ashurst suggested the Middle East is the second most popular region for renewable energy investment after North America, at a time when clean energy investment is outpacing fossil fuels.

The region is home to some of the largest renewable energy bets in the world, with Saudi wind expansion gathering pace. The UAE, for instance, is currently developing the Mohammed Bin Rashid Solar Park, the world’s largest concentrated solar power project in the world.

Around 26 percent of Middle East respondents in Ashurst’s survey said that they were presently investing in energy transition, marking the region as the most popular for current investment in renewables, while 11 percent added that they were considering investing.

In North America, the most popular region, 28 percent said that they were currently investing, with 11 percent stating they are considering investing.

Canadian nuclear projects bring economic benefits

Ontario Nuclear Refurbishment Economic Impact powers growth as Bruce Power's MCR and OPG's Darlington unit 2 refurbishment drive jobs, supply-chain spending, medical isotopes, clean baseload power, and lower GHG emissions across Ontario and Canada.

 

Key Points

It is the measured gains from Bruce Power's MCR and OPG's Darlington refurbishment in jobs, taxes, and clean energy.

✅ CAD7.6B-10.6B impact in Ontario; CAD8.1B-11.6B nationwide.

✅ Supports 60% nuclear supply, jobs, and medical isotopes.

✅ MCR and Darlington cut GHGs, drive innovation and supply chains.

 

The 13-year Major Component Replacement (MCR) project being undertaken as part of Bruce Power's life-extension programme, which officially began with a reactor taken offline earlier this year, will inject billions of dollars into Ontario's economy, a new report has found. Meanwhile, the major project to refurbish Darlington unit 2 remains on track for completion in 2020, Ontario Power Generation (OPG) has announced.

The Ontario Chamber of Commerce (OCC) said its report, Major Component Replacement Project Economic Impact Analysis, outlines an impartial assessment of the MCR programme and related manufacturing contracts across the supply chain. The report was commissioned by Bruce Power.

"Our analysis shows that Bruce Power's MCR project is a fundamental contributor to the Ontario economy. More broadly, the life-extension of the Bruce Power facility will provide quality jobs for Ontarians, produce a stable supply of medical isotopes for the world's healthcare system, and deliver economic benefit through direct and indirect spending," OCC President and CEO Rocco Rossi said."As Ontario's energy demand grows, nuclear truly is the best option to meet those demands with reduced GHG [greenhouse gas] emissions. The Bruce Power MCR Project will not only drive economic growth in the region, it will position Ontario as a global leader in nuclear innovation and expertise."

According to the OCC's economic analysis, the MCR's economic impact on Ontario is estimated to be between CAD7.6 billion (USD5.6 billion) and CAD10.6 billion. Nationally, its economic impact is estimated to be between CAD8.1 billion and CAD11.6 billion. It estimates that the federal government will receive CAD144 million in excise tax and CAD1.2 billion in income tax, while the provincial government will receive CAD300 million and CAD437 million. Ontario’s municipal governments are estimated to receive a collective CAD192 million in tax.

The nuclear industry currently provides 60% of Ontario’s daily energy supply needs, with Pickering life extension plans bolstering system reliability, and is made up of over 200 companies and more than 60,000 jobs across a diversity of sectors such as operations, manufacturing, skilled trades, healthcare, and research and innovation, the report notes.

Greg Rickford, Ontario's minister of Energy, Northern Development and Mines, and minister of Indigenous Affairs, said continued use of the Bruce generating station which recently set an operating record would create jobs and advance Ontario’s nuclear industrial sector. "It is great to see projects like the MCR that help make Ontario the best place to invest, do business and find a job," he said.

The MCR is part of Bruce Power's overall life-extension programme, which started in January 2016. Bruce 6 will be the first of the six Candu units to undergo an MCR which will take 46 months to complete and give the unit a further 30-35 years of operational life. The total cost of refurbishing Bruce units 3-8 is estimated at about CAD8 billion, in addition to CAD5 billion on other activities under the life-extension programme, which is scheduled for completion by 2053.

 

Darlington milestones

OPG's long-term refurbishment programme at Darlington, alongside SMR plans for the site announced by the province, began with unit 2 in 2016 after years of detailed planning and preparation. Reassembly of the reactor, which was disassembled last year, is scheduled for completion this spring, and the unit 2 refurbishment project remains on track for completion in early 2020. At the same time, final preparations are under way for the start of the refurbishment of unit 3.

"We've entered a critical phase on the project," Senior Vice President of Nuclear Refurbishment Mike Allen said. "OPG and our project partners continue to work as an integrated team to meet our commitments on Unit 2 and our other three reactors at Darlington Nuclear Generating Station."

A 350-tonne generator stator manufactured by GE in Poland is currently in transit to Canada, where it will be installed in Darlington 3's turbine hall as the province also breaks ground on its first SMR this year.

The 10-year Darlington refurbishment is due to be completed in 2026, while the province plans to refurbish Pickering B to extend output beyond that date.
