Tennessee Sen. Lamar Alexander offered a vision of the future for the Tennessee Valley Authority that includes more nuclear power generation and more energy conservation by consumers.

The chairman of the TVA congressional caucus said in a speech to a Tennessee municipal distributors group that nuclear should replace coal as TVA's major source of electric generation over the next 20 years, calling atomic power TVA's best option for "pollution-free, carbon-free," reliable generation.

The Senate's third-ranking Republican also said TVA, the nation's largest public utility, should do more to encourage energy conservation. Tennessee has the highest per capita use of electricity in the country.

Alexander offered his suggestions as the federal power agency begins a series of public hearings to develop a new Integrated Resource Plan to chart the agency's goals for the next two decades. The last plan was done in 1995. A draft for the new one is due next spring and a final version by early 2011.

TVA provides electricity to about 9 million consumers through 158 distributors in Tennessee and parts of Alabama, Mississippi, Kentucky, Georgia, North Carolina and Virginia.

Immediate public meetings are scheduled in Nashville, Chattanooga and Knoxville. Later sessions will be in Huntsville, Alabama, on July 28; Hopkinsville, Kentucky, on July 20; Starkville, Mississippi, on Aug. 4, and Memphis Tennessee on Aug. 6.

"We hope that we will get a large turnout of folks to discuss with us what options they think we should review in providing for future electric energy to the valley," TVA spokeswoman Barbara Martocci said, including suggestions on conservation and renewable energy.

Alexander attributed Tennessee's nation-leading electricity consumption to TVA's low residential rates, the region's high demand for air conditioning and possibly "that TVA and the distributors have not done as good a job in encouraging conservation and efficiency as other parts of the country."

Conservation "is really the low-hanging fruit. It is so much easier to have clean air and low costs if you use less," he said. "If we were just at the national average in terms of our individual use of electric power we could avoid building four nuclear power plants."

Alexander's recommendations for TVA also include eliminating virtually all greenhouse gas emissions from TVA's 11 coal-fired power plants or consider closing some plants, though "at the moment TVA needs all the capacity it has."

Alan Bradley, chief executive officer of Nashville Electric Service and president of the Tennessee municipal distributors group, praised Alexander's suggestions for a "cleaner vision of the future," but wondered what to tell customers convinced renewable solar and wind power should be in TVA's future.

Alexander, who drives a plug-in electric car in Washington, said wind power isn't reliable in the Southeast and solar power is still too expensive. But he hopes in 20 years solar will be affordable for most homeowners and electric cars will crowd the roads.

Scottish North Sea wind farm to resume construction after Covid-19 stoppage

NnG Offshore Wind Farm restarts construction off Scotland, backed by EDF Renewables and ESB, CfD 2015, 54 turbines, powering 375,000 homes, 500 jobs, delivering GBP 540 million, with Covid-19 safety measures and staggered workforce.

 

Key Points

A 54-turbine Scottish offshore project by EDF Renewables and ESB, resuming to power 375,000 homes and support 500 jobs.

✅ Awarded a CfD in 2015; 54 turbines off Scotland's east coast.

✅ Projected to power 375,000 homes and deliver GBP 540 million locally.

✅ Staggered workforce return with Covid-19 control measures and oversight.

 

Neart Na Gaoithe (NnG) Offshore Wind Farm, owned by  EDF Renewables and Irish firm ESB, stopped construction in March, even as the world's most powerful tidal turbine showcases progress in marine energy.

Project boss Matthias Haag announced last night the 54-turbine wind farm would restart construction this week, as the largest UK offshore wind farm begins supplying power, underscoring sector momentum.

Located off Scotland’s east coast, where wind farms already power millions of homes, it was awarded a Contract for Difference (CfD) in 2015 and will look to generate enough energy to power 375,000 homes.

It is expected to create around 500 jobs, and supply chain growth like GE's new offshore blade factory jobs shows wider industry momentum, while also delivering £540 million to the local economy.

Mr Haag, NnG project director, said the wind farm build would resume with a small, staggered workforce return in line social distancing rules, and with broader energy sector conditions, including Hinkley Point C setbacks that challenge the UK's blueprint.

He added: “Initially, we will only have a few people on site to put in place control measures so the rest of the team can start work safely later that week.

“Once that’s happened we will have a reduced workforce on site, including essential supervisory staff.

“The arrangements we have put in place will be under regular review as we continue to closely monitor Covid-19 and follow the Scottish Government’s guidance.”

NnG wind farm, a 54-turbine projects, was due to begin full offshore construction in June 2020 before the Covid-19 outbreak, at a time when a Scottish tidal project had just demonstrated it could power thousands of homes.

EDF Renewables sold half of the NnG project to Irish firm ESB in November last year, and parent company EDF recently saw the Hinkley C reactor roof lifted into place, highlighting progress alongside renewables.

The first initial payment was understood to be around £50 million.

NEW Hydro One shares down after Ontario government says CEO, board out

Hydro One Leadership Shakeup unsettles investors as Ontario government ousts CEO and board, pressuring shares; analysts cite political and regulatory risk, stock volatility, trimmed price targets, and dividend stability at the regulated utility.

 

Key Points

An abrupt CEO exit and board overhaul at Hydro One, driving share declines and raising political and regulatory risk.

✅ Shares fall as CEO retires and board resigns under provincial pressure.

✅ Analysts cut price targets; warn of political, regulatory risks.

✅ New board to pick CEO; province consults on compensation.

 

Hydro One Ltd. shares slid Thursday with some analysts sounding warnings of greater uncertainty after the new Ontario government announced the retirement of the electrical utility's chief executive and the replacement of its board of directors.

 After sagging by almost eight per cent in early trading on the Toronto Stock Exchange, following news that Q2 profit plunged 23% amid weaker electricity revenue, shares of the company were later down four per cent, or 81 cents, at $19.36 as of 11:42 a.m. ET.

On Wednesday, after stock markets had closed for the day, Ontario Premier Doug Ford announced the immediate retirement of Hydro One CEO Mayo Schmidt. He leaves with a $400,000 payout in lieu of post-retirement benefits and allowances, Hydro One said.

Doug Ford's government forces out Hydro One '$6-million man'

During the recent provincial election campaign, Ford vowed to fire Schmidt, who earned $6.2 million last year and whose salary wouldn't be reduced despite calls to cut electricity costs.

Paul Dobson, Hydro One's chief financial officer, will serve as acting CEO until a new top executive is selected.

Ford also said the entire board of directors of the utility would resign. Hydro One said a new board — four members of which will be nominated by the province — will select the company's next CEO, and the province will be consulted on the next leader's compensation.

A new board is expected to be formed by mid-August.

The provincial government is the largest single investor in Hydro One, holding a 47 per cent stake. The company was partly privatized by the former Liberal government in 2015, while the NDP has proposed to make hydro public again in Ontario to change course.

 

Doug Ford promises to keep Pickering nuclear plant open until 2024

In response to the government's move to supplant the utility's board and CEO, some analysts cautioned investors about too many unknowns in the near-term outlook, citing raised political or regulatory risks.

Analyst Jeremy Rosenfield of iA Securities cut his rating on Hydro One shares to hold from buy, and reduced his 12-month price target for the stock to $24 from $26.

Rosenfield said the stock is still a defensive investment supported by stable earnings and cash flows, good earnings growth and healthy dividend.

However, he said in a research note that "the heightened potential for further political interference in the province's electricity market and regulated utility framework represent key risk factors that are likely to outweigh Hydro One's fundamentals over the near term."

 

Potential challenge to find new CEO

Laurentian Bank Securities analyst Mona Nazir said in a research note that the magnitude of change all at once was "surprising but not shocking."

She said the agreement that will see Hydro One consult with the provincial government on matters involving executive pay could have an impact on the hiring of a new CEO for the utility.

"Given the government's open and public criticism of the company and a potential ceiling on compensation, it may be challenging to attract top talent to the position," she wrote.

Laurentian cut its rating on the Hydro One to hold and reduced its price target to $21 from $24.

Analysts at CIBC World Markets said investors face an uncertain future, noting parallels with debates at Manitoba Hydro over political direction.

"In particular, we are are concerned about the government meddling in with [power] rates," wrote Robert Catellier and Archit Kshetrapal in a research note, adding they believe the new provincial government is aiming for a 12 per cent reduction in customers' power bills.

CIBC reduced its price target on Hydro One's shares to $20.50 from its previous target of $24.

Canada and Manitoba invest in new turbines

Manitoba Clean Electricity Investment will upgrade hydroelectric turbines, expand a 230 kV transmission network, and deliver reliable, affordable low-carbon power, reducing greenhouse gas emissions and strengthening grid reliability across Portage la Prairie and Winnipeg River.

 

Key Points

Joint federal-provincial funding to upgrade hydro turbines and build a 230 kV grid, boosting reliable, low-carbon power.

✅ $314M for new turbines at Pointe du Bois (+52 MW capacity)

✅ $161.6M for 230 kV transmission in Portage la Prairie

✅ Cuts Brandon Generating Station emissions by ~37%

 

The governments of Canada and Manitoba have announced a joint investment of $475.6 million to strengthen Manitoba’s clean electricity grid that can support neighboring provinces with clean power and ensure continued supply of affordable and reliable low-carbon energy.

This federal-provincial investment provides $314 million for eight new hydroelectric turbines at the 75 MW Pointe du Bois Generating Station on the Winnipeg River, as well as $161.6 million to build a new 230 kV transmission network in the Portage la Prairie area, bolstering power sales to SaskPower and regional reliability.

The $314 million joint investment in the Pointe du Bois Renewable Energy Project includes $114.1 million from the Government of Canada and nearly $200 million from the Government of Manitoba. The joint investment will enable Manitoba Hydro to replace eight generating units that are at the end of their lifecycle, amid looming new generation needs for the province. The new, more efficient units will increase the capacity of the Pointe du Bois generating station by 52 MW.

The $161.6 million joint investment in the Portage Area Capacity Enhancement project includes $70.9 million from the Government of Canada and $90.6 million from the Government of Manitoba. The joint investment will support the construction of a new transmission line to enhance reliability for customers across southwest Manitoba and help Manitoba Hydro meet increasing demand, with projections that demand could double over the next two decades. By decreasing Manitoba’s reliance on its last grid-connected fossil-fuel generating station, this investment will reduce greenhouse gas emissions at the Brandon Generating Station by about 37%.

The federal government’s total contribution of $184.9 million is provided through the Green Infrastructure Stream of the Investing in Canada Plan, alongside efforts to improve interprovincial grid integration such as NB Power agreements with Hydro-Quebec that strengthen regional reliability. This federal funding is conditional on meeting Indigenous consultation requirements, as well as environmental assessment obligations. Including today’s announcement, the Green Infrastructure Stream has supported 38 infrastructure projects in Manitoba, for a total federal contribution of more than $766.8 million and a total provincial contribution of over $658.4 million.

“A key part of our economic plan is making Canada a clean electricity superpower. Today’s announcement in Manitoba will deliver clean, reliable, and affordable electricity to people and businesses across the province—and we will continue working to expand our clean electricity grid and create great careers for people from coast to coast to coast,” said Deputy Prime Minister and Finance Minister Chrystia Freeland.

The federal government will continue to invest in making Canada a clean electricity superpower, supporting provincial initiatives like Hydro-Quebec's fossil-free strategy that complement these investments to ensure Canadians from coast to coast to coast have the affordable and reliable clean electricity they need today and for generations to come.

“Manitoba Hydro is extremely pleased to be receiving this federal funding through the Green Infrastructure Stream of the Investing in Canada Infrastructure Program. The investments we are making in both these critical infrastructure projects will help provide Manitobans with energy for life and power our province’s economic growth with clean, reliable, renewable hydroelectricity. These projects build on our legacy of investments in renewable energy over the past 100 years, as we work towards a lower carbon future for all Manitobans,” said Jay Grewal, president and chief executive officer of Manitoba Hydro.

About 97% of Manitoba’s electricity is generated from clean hydro, with most of the remaining 3% coming from wind generation. Manitoba’s abundant clean electricity has resulted in Manitobans paying 9.455 ¢/kWh — the second-lowest electricity rate in Canada, though limits on serving new energy-intensive customers have been flagged recently.

Ontario’s Electricity Future: Balancing Demand and Emissions 

Ontario Electricity Transition faces surging demand, GHG targets, and federal regulations, balancing natural gas, renewables, battery storage, and grid reliability while pursuing net-zero by 2035 and cost-effective decarbonization for industry, EVs, and growing populations.

 

Key Points

Ontario Electricity Transition is the province's shift to a reliable, low-GHG grid via renewables, storage, and policy.

✅ Demand up 75% by 2050; procurement adds 4,000 MW capacity.

✅ Gas use rises to 25% by 2030, challenging GHG goals.

✅ Tripling wind and solar with storage can cut costs and emissions.

 

Ontario's electricity sector stands at a pivotal crossroads. Once a leader in clean energy, the province now faces the dual challenge of meeting surging demand while adhering to stringent greenhouse gas (GHG) reduction targets. Recent developments, including the expansion of natural gas infrastructure and proposed federal regulations, have intensified debates about the future of Ontario's energy landscape, as this analysis explains in detail.

Rising Demand and the Need for Expansion

Ontario's electricity demand is projected to increase by 75% by 2050, equivalent to adding four and a half cities the size of Toronto to the grid. This surge is driven by factors such as industrial electrification, population growth, and the transition to electric vehicles. In response, as Ontario confronts a looming shortfall in the coming years, the provincial government has initiated its most ambitious energy procurement plan to date, aiming to secure an additional 4,000 megawatts of capacity by 2030. This includes investments in battery storage and natural gas generation to ensure grid reliability during peak demand periods.

The Role of Natural Gas: A Controversial Bridge

Natural gas has become a cornerstone of Ontario's strategy to meet immediate energy needs. However, this reliance comes with environmental costs. The Independent Electricity System Operator (IESO) projects that by 2030, natural gas will account for 25% of Ontario's electricity supply, up from 4% in 2017. This shift raises concerns about the province's ability to meet its GHG reduction targets and to embrace clean power in practice. 

The expansion of gas-fired plants, including broader plans for new gas capacity, such as the Portlands Energy Centre in Toronto, has sparked public outcry. Environmental groups argue that these expansions could undermine local emissions reduction goals and exacerbate health issues related to air quality. For instance, emissions from the Portlands plant have surged from 188,000 tonnes in 2017 to over 600,000 tonnes in 2021, with projections indicating a potential increase to 1.65 million tonnes if the expansion proceeds as planned. 

Federal Regulations and Economic Implications

The federal government's proposed clean electricity regulations aim to achieve a net-zero electricity sector by 2035. However, Ontario's government has expressed concerns that these regulations could impose significant financial burdens. An analysis by the IESO suggests that complying with the new rules would require doubling the province's electricity generation capacity, potentially adding $35 billion in costs by 2050, while other estimates suggest that greening Ontario's grid could cost $400 billion over time. This could result in higher residential electricity bills, ranging from $132 to $168 annually starting in 2033.

Pathways to a Sustainable Future

Experts advocate for a diversified approach to decarbonization that balances environmental goals with economic feasibility. Investments in renewable energy sources, such as new wind and solar resources, along with advancements in energy storage technologies, are seen as critical components of a sustainable energy strategy. Additionally, implementing energy efficiency measures and modernizing grid infrastructure can enhance system resilience and reduce emissions. 

The Ontario Clean Air Alliance proposes phasing out gas power by 2035 through a combination of tripling wind and solar capacity and investing in energy efficiency and storage solutions. This approach not only aims to reduce emissions but also offers potential cost savings compared to continued reliance on gas-fired generation. 

Ontario's journey toward a decarbonized electricity grid is fraught with challenges, including balancing reliability, clean, affordable electricity, and environmental sustainability. While natural gas currently plays a significant role in meeting the province's energy needs, its long-term viability as a bridge fuel remains contentious. The path forward will require careful consideration of technological innovations, regulatory frameworks, and public engagement to ensure a clean, reliable, and economically viable energy future for all Ontarians.

Big prizes awarded to European electricity prediction specialists

Electricity Grid Flow Prediction leverages big data, machine learning, and weather analytics to forecast power flows across smart grids, enhancing reliability, reducing blackouts and curtailment, and optimizing renewable integration under EU Horizon 2020 innovation.

 

Key Points

Short-term forecasting of power flows using big data, weather inputs, and machine learning to stabilize smart grids.

✅ Uses big data, weather, and ML for 6-hour forecasts

✅ Improves reliability, cuts blackouts and energy waste

✅ Supports smart grids, renewables, and grid balancing

 

Three European prediction specialists have won prizes worth €2 million for developing the most accurate predictions of electricity flow through a grid

The three winners of the Big Data Technologies Horizon Prize received their awards at a ceremony on 12th November in Austria.

The first prize of €1.2 million went to Professor José Vilar from Spain, while Belgians Sofie Verrewaere and Yann-Aël Le Borgne came in joint second place and won €400,000 each.

The challenge was open to individuals groups and organisations from countries taking part in the EU’s research and innovation programme, Horizon 2020.

Carlos Moedas, Commissioner for Research, Science and Innovation, said: “Energy is one of the crucial sectors that are being transformed by the digital grid worldwide.

“This Prize is a good example of how we support a positive transformation through the EU’s research and innovation programme, Horizon 2020.

“For the future, we have designed our next programme, Horizon Europe, to put even more emphasis on the merger of the physical and digital worlds across sectors such as energy, transport and health.”

The challenge for the applicants was to create AI-driven software that could predict the likely flow of electricity through a grid taking into account a number of factors including the weather and the generation source (i.e. wind turbines, solar cells, etc).

Using a large quantity of data from electricity grids, EU smart meters, combined with additional data such as weather conditions, applicants had to develop software that could predict the flow of energy through the grid over a six-hour period.

Commissioner for Digital Economy and Society Mariya Gabriel said: “The wide range of possible applications of these winning submissions could bring tangible benefits to all European citizens, including efforts to tackle climate change with machine learning across sectors.”

The decision to focus on energy grids for this particular prize was driven by a clear market need, including expanding HVDC technology capabilities.

Today’s energy is produced at millions of interconnected and dispersed unpredictable sites such as wind turbines, solar cells, etc., so it is harder to ensure that electricity supply matches the demand at all times.

This complexity means that huge amounts of data are produced at the energy generation sites, in the grid and at the place where the energy is consumed.

Being able to make accurate, short-term predictions about power grid traffic is therefore vital to reduce the risks of blackouts or, by enabling utilities to use AI for energy savings, limit waste of energy.

Reliable predictions can also be used in fields such as biology and healthcare. The predictions can help to diagnose and cure diseases as well as to allocate resources where they are most needed.

Ultimately, the winning ideas are set to be picked up by the energy sector in the hopes of creating smarter electricity infrastructure, more economic and more reliable power grids.
