TVA, which has an increased emphasis on clean energy, renewable energy and energy efficiency, has two contracts for renewable energy with Waste Management in Tennessee.

TVA has just signed a 20-year contract with Waste Management to buy 4.8 megawatts of power from a landfill-biogas facility at Camden in West Tennessee. That contract is the first in TVA's new renewable standard offer initiative.

TVA pays a set price — or a "standard offer" — for renewable power based on the time of day the electricity is available to the TVA power grid. TVA's Renewable Standard Offer initially will be limited to a total of 100 megawatts from all participants, with no single renewable technology representing more than 50 megawatts of the total.

The Chestnut Ridge facility along the Knox-Anderson county line has been providing electricity for about 1,600 homes that are KUB customers. TVA and Waste Management have been partners in the Chestnut Ridge power contract for nearly 20 years.

TVA also buys power — 3 megawatts — from methane facilities at Middle Point Landfill in Murfreesboro, Tenn., and 8 megawatts from the city of Memphis wastewater treatment plant.

TVA spokesman Mike Bradley said the agency does not discuss pricing for the renewable energy contracts, citing the information as "business sensitive."

TVA, which also gets renewable energy from wind, solar and biomass and customers, has an agreement with the state of Tennessee to buy up to 5 megawatts of electricity from a solar farm being built in Haywood County in West Tennessee. The University of Tennessee and the state are developing that facility.

The agency has added 1,625 megawatts of wind energy — 300 megawatts from an Illinois company and 29 megawatts from the Buffalo Mountain turbines near Oliver Springs.

TVA's Generation Partners program — for very small power producers — includes more than 560 participants that produce about 65 megawatts of power from solar biomass, wind and low-impact hydro generation.

Energy crisis: EU outlines possible gas price cap strategies

EU Gas Price Cap Strategies aim to curb inflation during an energy crisis by capping wholesale gas and electricity generation costs, balancing supply and demand, mitigating subsidies, and safeguarding supply security amid Russia-Ukraine shocks.

 

Key Points

Temporary EU measures to cap gas and power prices, curb inflation, manage demand, and protect supply security.

✅ Flexible temporary price limits to secure gas supplies

✅ Framework cap on gas for electricity generation with demand checks

✅ Risk: subsidies, higher demand, and market distortions

 

The European Commission has outlined possible strategies to cap gas prices as the bloc faces a looming energy crisis this winter. 

Member states are divided over the emergency measures designed to pull down soaring inflation amid Russia's war in Ukraine. 

One proposal is a temporary "flexible" limit on gas prices to ensure that Europe can continue to secure enough gas, EU energy commissioner Kadri Simson said on Tuesday. 

Another option could be an EU-wide "framework" for a price cap on gas used to generate electricity, which would be combined with measures to ensure gas demand does not rise as a result, she said.

EU leaders are meeting on Friday to debate gas price cap strategies amid warnings that Europe's energy nightmare could worsen this winter.

Last week, France, Italy, Poland and 12 other EU countries urged the Commission to propose a broader price cap targeting all wholesale gas trade. 

But Germany -- Europe's biggest gas buyer -- and the Netherlands are among those opposing electricity market reforms within the bloc.

Russia has slashed gas deliveries to Europe since its February invasion of Ukraine, with Moscow blaming the cuts on Western sanctions imposed in response to the invasion, as the EU advances a plan to dump Russian energy across the bloc.

Since then, the EU has agreed on emergency laws to fill gas storage and windfall profit levies to raise money to help consumers with bills. 

Price cap critics
One energy analyst told Euronews that an energy price cap was an "unchartered territory" for the European Union. 

The EU's energy sector is largely liberalised and operates under the fundamental rules of supply and demand, making rolling back electricity prices complex in practice.

"My impression is that member states are looking at prices and quantities in isolation and that's difficult because of economics," said Elisabetta Cornago, a senior energy researcher at the Centre for European Reform.

"It's hard to picture such a level of market intervention This is uncharted territory."

The energy price cap would "quickly start costing billions" because it would force governments to continually subsidise the difference between the real market price and the artificially capped price, another expert said. 

"If you are successful and prices are low and you still get gas, consumers will increase their demand: low price means high demand. Especially now that winter is coming," said Bram Claeys, a senior advisor at the Regulatory Assistance Project.

Ireland: We are the global leaders in taking renewables onto the grid

Ireland 65% Renewable Grid Capability showcases world leading integration of intermittent wind and solar, smart grid flexibility, EU-SysFlex learnings, and the Celtic Interconnector to enhance stability, exports, and energy security across the European grid.

 

Key Points

Ireland can run its isolated power system with 65% variable wind and solar, informing EU grid integration and scaling.

✅ 65% system non-synchronous penetration on an isolated grid

✅ EU-SysFlex roadmap supports large-scale renewables integration

✅ Celtic Interconnector adds 700MW capacity and stability

 

Ireland is now able to cope with 65% of its electricity coming from intermittent electricity sources like wind and solar, as highlighted by Ireland's green electricity outlook today – an expertise Energy Minister Denish Naugthen believes can be replicated on a larger scale as Europe moves towards 50% renewable power by 2030.

Denis Naughten is an Irish politician who serves as Minister for Communications, Climate Action and Environment since May 2016.

Naughten spoke to editor Frédéric Simon on the sidelines of a EURACTIV event in the European  Parliament to mark the launch of EU-SysFlex, an EU-funded project, which aims to create a long-term roadmap for the large-scale integration of renewable energy on electricity grids.

What is the reason for your presence in Brussels today and the main message that you came to deliver?

The reason that I’m here today is that we’re going to share the knowledge what we have developed in Ireland, right across Europe. We are now the global leaders in taking variable renewable electricity like wind and solar onto our grid.

We can take a 65% loading on to the grid today – there is no other isolated grid in the world that can do that. We’re going to get up to 75% by 2020. This is a huge technical challenge for any electricity grid and it’s going to be a problem that is going to grow and grow across Europe, even as Europe's electricity demand rises in the coming years, as we move to 50% renewables onto our grid by 2030.

And our knowledge and understanding can be used to help solve the problems right across Europe. And the sharing of technology can mean that we can make our own grid in Ireland far more robust.

What is the contribution of Ireland when it comes to the debate which is currently taking place in Europe about raising the ambition on renewable energy and make the grid fit for that? What are the main milestones that you see looking ahead for Europe and Ireland?

It is a challenge for Europe to do this, but we’ve done it Ireland. We have been able to take a 65% loading of wind power on our grid, with Irish wind generation hitting records recently, so we can replicate that across Europe.

Yes it is about a much larger scale and yes, we need to work collaboratively together, reflecting common goals for electricity networks worldwide – not just in dealing with the technical solutions that we have in Ireland at the fore of this technology, but also replicating them on a larger scale across Europe.

And I believe we can do that, I believe we can use the learnings that we have developed in Ireland and amplify those to deal with far bigger challenges that we have on the European electricity grid.

Trialogue talks have started at European level about the reform of the electricity market. There is talk about decentralised energy generation coming from small-scale producers. Do you see support from all the member states in doing that? And how do you see the challenges ahead on a political level to get everyone on board on such a vision?

I don’t believe there is a political problem here in relation to this. I think there is unanimity across Europe that we need to support consumers in producing electricity for self-consumption and to be able to either store or put that back into the grid.

The issues here are more technical in nature. And how you support a grid to do that. And who actually pays for that. Ireland is very much a microcosm of the pan-European grid and how we can deal with those challenges.

What we’re doing at the moment in Ireland is looking at a pilot scheme to support consumers to generate their own electricity to meet their own needs and to be able to store that on site.

I think in the years to come a lot of that will be actually done with more battery storage in the form of electric vehicles and people would be able to transport that energy from one location to another as and when it’s needed. In the short term, we’re looking at some novel solutions to support consumers producing their own electricity and meeting their own needs.

So I think this is complex from a technical point of view at the moment, I don’t think there is an unwillingness from a political perspective to do it, and I think working with this particular initiative and other initiatives across Europe, we can crack those technical challenges.

To conclude, last year, the European Commission allocated €4 million to a project to link up the Irish electricity grid to France. How is that going to benefit Ireland? And is that related to worries that you may have over Brexit?

The plan, which is called the Celtic Interconnector, is to link France with the Irish electricity grid. It’s going to have a capacity of about 700MW. It allows us to provide additional stability on our grid and enables us to take more renewables onto the grid. It also allows us to export renewable electricity onto the main European grid as well, and provide stability to the French network.

So it’s a benefit to both individual networks as well as allowing far more renewables onto the grid. We’ve been working quite closely with RTE in France and with both regulators. We’re hoping to get the support of the European Commission to move it now from the design stage onto the construction stage. And I understand discussions are ongoing with the Commission at present with regard to that.

And that is going to diversify potential sources of electricity coming in for Ireland in a situation which is pretty uncertain because of Brexit, correct?

Well, I don’t think there is uncertainty because of Brexit in that we have agreements with the United Kingdom, we’re still going to be part of the broader energy family in relation to back-and-forth supply across the Irish Sea, with grid reinforcements in Scotland underscoring reliability needs.  But I think it is important in terms of meeting the 15% interconnectivity that the EU has set in relation to electricity.

And also in relation of providing us with an alternative support in relation to electricity supply outside of Britain. Because Britain is now leaving the European Union and I think this is important from a political point of view, and from a broader energy security point of view. But we don’t see it in the short term as causing threats in relation to security of supply.

Investor: Hydro One has too many unknowns to be a good investment

Hydro One investment risk reflects Ontario government influence, board shakeup, Avista acquisition uncertainty, regulatory hearings, dividend growth prospects, and utility M&A moves in Peterborough, with stock volatility since the 2015 IPO.

 

Key Points

Hydro One investment risk stems from political control, governance turnover, regulatory outcomes, and uncertain M&A.

✅ Ontario retains near-50% stake, affecting autonomy and policy risk

✅ Board overhaul and CEO exit create governance uncertainty

✅ Avista deal, OEB hearings, local utility M&A drive outcomes

 

Hydro One may be only half-owned by the province on Ontario but that’s enough to cause uncertainty about the company’s future, thus making for an investment risk, says Douglas Kee of Leon Frazer & Associates.

Since its IPO in November of 2015, Hydro One has seen its share of ups and downs, including a Q2 profit decline earlier this year, mostly downs at this point. Currently trading at $19.87, the stock has lost 11 per cent of its value in 2018 and 12 per cent over the last 12 months, despite a one-time gain boosting Q2 profit that followed a court ruling.

This year has been a turbulent one, to say the least, as newly elected Ontario premier Doug Ford made good this summer on his campaign promise re Hydro One by forcing the resignation of the company’s 14-person board of directors along with the retirement of its chief executive, an event that saw Hydro One shares fall amid the turmoil. An interim CEO has been found and a new 10-person board and chairman put in place, but Kee says it’s unclear what impact the shakeup will ultimately have, other than delaying a promising-looking deal to purchase US utility Avista Corp, with the companies moving to ask the U.S. regulator to reconsider the order.

 

Douglas Kee’s take on Hydro One stock

“We looked at Hydro One a couple of times two years ago and just decided that with the Ontario government’s still owning a big chunk of the company … there are other public companies where you get the same kind of yield, the same kind of dividend growth, so we just avoided it,” says Kee, managing director and chief investment officer with Leon Frazer & Associates, to BNN Bloomberg.

“The old board versus the new board, I’m not sure that there’s much of an improvement. It was politics more than anything,” he says. “The unfortunate part is that the acquisition they were making in the United States is kind of on hold for now. The regulatory procedures have gone ahead but they are worried, and I guess the new board has to make a decision whether to go ahead with it or not.”

“Their transmissions side is coming up for regulatory hearings next year, which could be difficult in Ontario,” says Kee. “The offset to that is that there are a lot of municipal distributions systems in Ontario that may be sold — they bought one in Peterborough recently, which was a good deal for them. There may be more of that coming too.”

Last month, Hydro One reached an agreement with the City of Peterborough to buy its Peterborough Distribution utility which serves about 37,000 customers for $105 million. Another deal to purchase Orillia Power Distribution Corp for $41 million has been cancelled after an appeal to the Ontario Energy Board was denied in late August. Hydro One’s sought-after Avista Corp acquisition is reported to be worth $7 billion.

Niagara Falls Powerhouse Gets a Billion-Dollar Upgrade for the 21st Century

Sir Adam Beck I refurbishment boosts hydropower capacity in Niagara, upgrading turbines, generators, and controls for Ontario Power Generation. The billion-dollar project enhances grid reliability, clean energy output, and preserves heritage architecture.

 

Key Points

An OPG upgrade of the historic Niagara plant to replace equipment, add 150 MW, and extend clean power life.

✅ Adds at least 150 MW to Ontario's clean energy supply

✅ Replaces turbines, generators, transformers, and controls

✅ Creates hundreds of skilled construction and engineering jobs

 

Ontario's iconic Sir Adam Beck hydroelectric generating station in Niagara is set to undergo a massive, billion-dollar refurbishment. The project will significantly boost the power station's capacity and extend its lifespan, with efforts similar to revitalizing older dams seen across North America, ensuring a reliable supply of clean energy for decades to come.


A Century of Power Generation

The Sir Adam Beck generating stations have played a pivotal role in Ontario's power grid for over a century. The first generating station, Sir Adam Beck I, went online in 1922, followed by Sir Adam Beck II in 1954. A third station, the Sir Adam Beck Pump Generating Station, was added in 1957, highlighting the role of pumped storage in Ontario for grid flexibility, Collectively, they form one of the largest hydroelectric complexes in the world, harnessing the power of the Niagara River.


Preparing for Increased Demand

The planned refurbishment of Sir Adam Beck I is part of Ontario Power Generation's broader strategy, which includes the life extension at Pickering NGS among other initiatives, to meet the growing energy demands of the province. With the population expanding and a shift towards electrification, Ontario will need to increase its power generation capacity while also focusing on sustainable and clean sources of energy.


Billions to Secure Sustainable Energy

The project to upgrade Sir Adam Beck I carries a hefty price tag of over a billion dollars but is considered a vital investment in Ontario's energy infrastructure, and recent OPG financial results underscore the utility's capacity to manage long-term capital plans. The refurbishment will see the replacement of aging turbines, generators, and transformers, and a significant upgrade to the station's control systems. Following the refurbishment, the output of Sir Adam Beck I is expected to increase by at least 150 megawatts – enough to power thousands of homes and businesses.


Creating Green Jobs

In addition to securing the province's energy future, the upgrade presents significant economic benefits to the Niagara region. The project will create hundreds of well-paying construction and engineering jobs, similar to employment from the continued operation of Pickering Station across Ontario, during the several years it will take to implement the upgrades.


Commitment to Hydropower

Ontario Power Generation (OPG) has long touted the benefits of hydropower as a reliable, renewable, and affordable source of energy, even as an analysis of rising grid emissions underscores the importance of clean generation to meet demand. The Sir Adam Beck complex is a shining example and represents a significant asset in the fight against climate change while providing reliable power to Ontario's businesses and residents.


Balancing Energy Needs with Heritage Preservation

The refurbishment will also carefully integrate modern design with the station's heritage elements, paralleling decisions such as the refurbishment of Pickering B that weigh system needs and public trust. Sir Adam Beck I is a designated historic site, and the project aims to preserve the station's architectural significance while enhancing its energy generation capabilities.

Hydropower Plants to Support Solar and Wind Energy

Solar-Wind-Water West Africa integrates hydropower with solar and wind to boost grid flexibility, clean electricity, and decarbonization, leveraging the West African Power Pool and climate data modeling reported in Nature Sustainability.

 

Key Points

A strategy using hydropower to balance solar and wind, enabling reliable, low-carbon electricity across West Africa.

✅ Hydropower dispatch covers solar and wind shortfalls.

✅ Regional interconnection via West African Power Pool.

✅ Cuts CO2 versus gas while limiting new dam projects.

 

Hydropower plants can support solar and wind power, rather unpredictable by nature, in a climate-friendly manner. A new study in the scientific journal Nature Sustainability has now mapped the potential for such "solar-wind-water" strategies for West Africa: an important region where the power sector is still under development, amid IEA investment needs for universal access, and where generation capacity and power grids will be greatly expanded in the coming years. "Countries in West Africa therefore now have the opportunity to plan this expansion according to strategies that rely on modern, climate-friendly energy generation," says Sebastian Sterl, energy and climate scientist at Vrije Universiteit Brussel and KU Leuven and lead author of the study. "A completely different situation from Europe, where power supply has been dependent on polluting power plants for many decades - which many countries now want to rid themselves of."

Solar and wind power generation is increasing worldwide and becoming cheaper and cheaper. This helps to keep climate targets in sight, but also poses challenges. For instance, critics often argue that these energy sources are too unpredictable and variable to be part of a reliable electricity mix on a large scale, though combining multiple resources can enhance project performance.

"Indeed, our electricity systems will have to become much more flexible if we are to feed large amounts of solar and wind power into the grid. Flexibility is currently mostly provided by gas power plants. Unfortunately, these cause a lot of CO2 emissions," says Sebastian Sterl, energy and climate expert at Vrije Universiteit Brussel (VUB) and KU Leuven. "But in many countries, hydropower plants can be a fossil fuel-free alternative to support solar and wind energy. After all, hydropower plants can be dispatched at times when insufficient solar and wind power is available."

The research team, composed of experts from VUB, KU Leuven, the International Renewable Energy Agency (IRENA), and Climate Analytics, designed a new computer model for their study, running on detailed water, weather and climate data. They used this model to investigate how renewable power sources in West Africa could be exploited as effectively as possible for a reliable power supply, even without large-scale storage, in line with World Bank support for wind in developing countries. All this without losing sight of the environmental impact of large hydropower plants.

"This is far from trivial to calculate," says Prof. Wim Thiery, climate scientist at the VUB, who was also involved in the study. "Hydroelectric power stations in West Africa depend on the monsoon; in the dry season they run on their reserves. Both sun and wind, as well as power requirements, have their own typical hourly, daily and seasonal patterns. Solar, wind and hydropower all vary from year to year and may be impacted by climate change, including projections that wind resources shift southward in coming years. In addition, their potential is spatially very unevenly distributed."

West African Power Pool

The study demonstrates that it will be particularly important to create a "West African Power Pool", a regional interconnection of national power grids to serve as a path to universal electricity access across the region. Countries with a tropical climate, such as Ghana and the Ivory Coast, typically have a lot of potential for hydropower and quite high solar radiation, but hardly any wind. The drier and more desert-like countries, such as Senegal and Niger, hardly have any opportunities for hydropower, but receive more sunlight and more wind. The potential for reliable, clean power generation based on solar and wind power, supported by flexibly dispatched hydropower, increases by more than 30% when countries can share their potential regionally, the researchers discovered.

All measures taken together would allow roughly 60% of the current electricity demand in West Africa to be met with complementary renewable sources, despite concerns about slow greening of Africa's electricity, of which roughly half would be solar and wind power and the other half hydropower - without the need for large-scale battery or other storage plants. According to the study, within a few years, the cost of solar and wind power generation in West Africa is also expected to drop to such an extent that the proposed solar-wind-water strategies will provide cheaper electricity than gas-fired power plants, which currently still account for more than half of all electricity supply in West Africa.

Better ecological footprint

Hydropower plants can have a considerable negative impact on local ecology. In many developing countries, piles of controversial plans for new hydropower plants have been proposed. The study can help to make future investments in hydropower more sustainable. "By using existing and planned hydropower plants as optimally as possible to massively support solar and wind energy, one can at the same time make certain new dams superfluous," says Sterl. "This way two birds can be caught with one stone. Simultaneously, one avoids CO2 emissions from gas-fired power stations and the environmental impact of hydropower overexploitation."

Global relevance

The methods developed for the study are easily transferable to other regions, and the research has worldwide relevance, as shown by a US 80% study on high variable renewable shares. Sterl: "Nearly all regions with a lot of hydropower, or hydropower potential, could use it to compensate shortfalls in solar and wind power." Various European countries, with Norway at the front, have shown increased interest in recent years to deploy their hydropower to support solar and wind power in EU countries. Exporting Norwegian hydropower during times when other countries undergo solar and wind power shortfalls, the European energy transition can be advanced.
