The disastrous coal ash flood at a Tennessee Valley Authority power plant should be a "wake-up call" for greater environmental and regulatory oversight, Tennessee Sen. Bob Corker said.

The Chattanooga Republican took a helicopter tour over the site near Harriman where 1.1 billion gallons of ash sludge surged from a collapsed retention pond two weeks ago. He was briefed by TVA officials and met with affected residents.

Later he told a news conference that TVA has no plans to use that holding pond again, though the federal utility hasn't decided how it will dispose of fly ash in the future at the 1950s-era Kingston Fossil Plant.

Corker said it was too soon to say if "bad luck or malfeasance" was to blame, but he pressed TVA to make things right for the victims, including not only the three homeowners whose houses were destroyed but a broader population of retirees and lake lovers drawn to the idyllic banks of the vast Tennessee River system.

"Whether it was the heavy amounts of rain, whether it was something else that an engineer should have caught but didn't" that caused the dike to breach, he said, the result is "this is a devastated area now."

"I think it is wake-up call for both the federal government and state entities that are involved in inspecting these particular facilities to make sure that we do everything we can to make sure the integrity is there," he said.

Gov. Phil Bredesen has promised to review state regulatory practices and the federal Environmental Protection Agency has suggested taking greater oversight of these coal waste piles. Corker said he was talking with both the governor and EPA about the issue.

State, EPA and TVA staff have been monitoring air, water and soil for toxins up to 4 miles from the 300-acre waste area since the mishap on December 22, and those efforts are continuing.

State Environment and Conservation Department spokeswoman Tisha Calabrese-Benton said new tests of 22 private wells found all within drinking water standards. The state continues to sample water intakes for the towns of Rockwood and Kingston and "no problem has been found with any municipal water supply," she said.

Despite those assurances, Corker said when he was handed a cup of tap water to drink during his tour he hesitated. "I did drink it," he said after a pause. "And I feel pretty good."

TVA spokeswoman Barbara Martocci said the Knoxville-based federal utility has yet to put a price tag on the cleanup, which currently involves 150 people, 40 contractors and 74 pieces of heavy equipment.

Corker said he doubted TVA, a self-supporting federal corporation "is going to be coming to the federal government" for help paying for the spill. "They need to solve this within the boundaries of their own entity," he said. He wouldn't rule out a TVA electric rate increase.

TVA will open an outreach center for victims on Tuesday in Kingston and will hold another public meeting in Harriman Tuesday evening with citizens on the cleanup effort.

The U.S. Senate Environment and Public Works Committee plans a hearing on the spill in Washington on Thursday. TVA President Tom Kilgore and critic Steve Smith of the Southern Alliance for Clean Energy are to testify.

"I am sure there will be people in our country that will feel (the spill) says a lot about" the environmental problems with coal-generated electricity, including mountaintop removal mining practices, Corker said.

"But I think coal is going to be here for a while," he said.

"In the interim, I think we need to be focused on making sure that as we use it, it is used in a clean way and a responsible way, and certainly that these types of issues do not happen again."

Knoxville-based TVA supplies electricity to Tennessee, Mississippi, Alabama, Kentucky, Georgia, North Carolina and Virginia.

Energy storage poised to tackle grid challenges from rising EVs as mobile chargers bring new flexibility

EV Charging Grid Readiness addresses how rising EV adoption, larger batteries, and fast charging affect electric utilities, using vehicle-to-grid, energy storage, mobile and temporary chargers, and smart charging to mitigate distribution stress.

 

Key Points

Planning and tech to manage EV load growth with V2G, storage and smart charging to avoid overloads on distribution grids.

✅ Lithium-ion costs may drop 60%, enabling new charger models

✅ Mobile and temporary chargers buffer local distribution peaks

✅ Smart charging and V2G defer transformer and feeder upgrades

 

The impacts of COVID-19 likely mean flat electric vehicle (EV) sales this year, but a trio of new reports say the long-term outlook is for strong growth — which means the electric grid and especially state power grids will need to respond.

As EV adoption grows, newer vehicles will put greater stress on the electric grid due to their larger batteries and capacity for faster charging, according to Rhombus Energy Solutions, while a DOE lab finds US electricity demand could rise 38% as EV adoption scales. A new white paper from the company predicts the cost of lithium-ion batteries will drop by 60% over the next decade, helping enable a new set of charging solutions.

Meanwhile, mobile and temporary EV charging will grow from 0.5% to 2% of the charging market by 2030, according to new Guidehouse research. The overall charging market is expected to reach reach almost $16 billion in revenues in 2020 and more than $60 billion by 2030. ​A third report finds long-range EVs are growing their share of the market as well, and charging them could cause stress to electric distribution systems. 

"One can expect that the number of EVs in fleets will grow very rapidly over the next ten years," according to Rhombus' report. But that means many fleet staging areas will have trouble securing sufficient charging capacity as electric truck fleets scale up.

"Given the amount of time it takes to add new megawatt-level power feeds in most cities (think years), fleet EVs will run into a significant 'power crisis' by 2030," according to Rhombus.

"Grid power availability will become a significant problem for fleets as they increase the number of electric vehicles they operate," Rhombus CEO Rick Sander said in a statement. "Integrating energy storage with vehicle-to-grid capable chargers and smart [energy management system] solutions as seen in California grid stability efforts is a quick and effective mitigation strategy for this issue."

Along with energy storage, Guidehouse says a new, more flexible approach to charger deployment enabled by grid coordination strategies will help meet demand. That means chargers deployed by a van or other mobile stations, and "temporary" chargers that can help fleets expand capacity. 

According to Guidehouse, the temporary units "are well positioned to de-risk large investments in stationary charging infrastructure" while also providing charge point networks and service providers "with new capabilities to flexibly supply predictable changes in EV transportation behaviors and demand surges."

"Mobile charging is a bit of a new area in the EV charging scene. It primarily leverages batteries to make chargers mobile, but it doesn't necessarily have to," Guidehouse Senior Research Analyst Scott Shepard told Utility Dive. 

"The biggest opportunity is with the temporary charging format," said Shepard. "The bigger units are meant to be located at a certain site for a period of time. Those units are interesting because they create a little more scale-ability for sites and a little risk mitigation when it comes to investing in a site."

"Utilities could use temporary chargers as a way to provide more resilient service, using these chargers in line with on-site generation," Shepard said.

Increasing rates of EV adoption, combined with advances in battery size and charging rates, "will impact electric utility distribution infrastructure at a higher rate than previously projected," according to new analysis from FleetCarma.

The charging company conducted a study of over 3,900 EVs, illustrating the rapid change in vehicle capabilities in just the last five years. According to FleetCarma, today's EVs use twice as much energy and draw it at twice the power level. The long-range EV has increased as a proportion of new electric vehicle sales from 14% in 2014 to 66% in 2019 in the United States, it found.

Long-range EVs "are very different from older electric vehicles: they are driven more, they consume more energy, they draw power at a higher level and they are less predictable," according to FleetCarma.

Guidehouse analysts say grid modernization efforts and energy storage can help smooth the impacts of charging larger vehicles. 

Mobile and temporary charging solutions can act as a "buffer" to the distribution grid, according to Guidehouse's report, allowing utilities to avoid or defer some transmission and distribution upgrade costs that could be required due to stress on the grid from newer vehicles.

"At a high level, there's enough power and energy to supply EVs with proper management in place," said Shepard. "And in a lot of different locations, those charging deployments will be built in a way that protects the grid. Public fast charging, large commercial sites, they're going to have the right infrastructure embedded."

"But for certain areas of the grid where there is low visibility, there is the potential for grid disruption and questions about whether the UK grid can cope with EV demand," said Shepard. "This has been on the mind of utilities but never realized: overwhelming residential transformers."

As EVs with higher charging and energy capacities are connected to the grid, Shepard said, "you are going to start to see some of those residential systems come under pressure, and probably see increased incidences of having to upgrade transformers." Some residential upgrades can be deferred through smarter charging programs, he added.

Global: Nuclear power: what the ‘green industrial revolution’ means for the next three waves of reactors

UK Nuclear Energy Ten Point Plan outlines support for large reactors, SMRs, and AMRs, funding Sizewell C, hydrogen production, and industrial heat to reach net zero, decarbonize transport and heating, and expand clean electricity capacity.

 

Key Points

A UK plan backing large, small, and advanced reactors to drive net zero via clean power, hydrogen, and industrial heat.

✅ Funds large plants (e.g., Sizewell C) under value-for-money models

✅ Invests in SMRs for factory-built, modular, lower-cost deployment

✅ Backs AMRs for high-temperature heat, hydrogen, and industry

 

The UK government has just announced its “Ten Point Plan for a Green Industrial Revolution”, in which it lays out a vision for the future of energy, transport and nature in the UK. As researchers into nuclear energy, my colleagues and I were pleased to see the plan is rather favourable to new nuclear power.

It follows the advice from the UK’s Nuclear Innovation and Research Advisory Board, pledging to pursue large power plants based on current technology, and following that up with financial support for two further waves of reactor technology (“small” and “advanced” modular reactors).

This support is an important part of the plan to reach net-zero emissions by 2050, as in the years to come nuclear power will be crucial to decarbonising not just the electricity supply but the whole of society.

This chart helps illustrate the extent of the challenge faced:

Efforts to reduce emissions have so far only partially decarbonised the electricity generation sector. Reaching net zero will require immense effort to also decarbonise heating, transport, as well as shipping and aviation. The plan proposes investment in hydrogen production and electric vehicles to address these three areas – which will require, as advocates of nuclear beyond electricity argue, a lot more energy generation.

Nuclear is well-placed to provide a proportion of this energy. Reaching net zero will be a huge challenge, and industry leaders warn it may be unachievable without nuclear energy. So here’s what the announcement means for the three “waves” of nuclear power.

Who will pay for it?
But first a word on financing. To understand the strategy, it is important to realise that the reason there has been so little new activity in the UK’s nuclear sector since the 1990s is due to difficulty in financing. Nuclear plants are cheap to fuel and operate and last for a long time. In theory, this offsets the enormous upfront capital cost, and results in competitively priced electricity overall.

But ever since the electricity sector was privatised, governments have been averse to spending public money on power plants. This, combined with resulting higher borrowing costs and cheaper alternatives (gas power), has meant that in practice nuclear has been sidelined for two decades. While climate change offers an opportunity for a revival, these financial concerns remain.

Large nuclear
Hinkley Point C is a large nuclear station currently under construction in Somerset, England. The project is well-advanced, with its first reactor installed and due to come online in the middle of this decade. While the plant will provide around 7% of current UK electricity demand, its agreed electricity price is relatively expensive.

The government’s new plan states: “We are pursuing large-scale new nuclear projects, subject to value-for-money.” This is likely a reference to the proposed Sizewell C in Suffolk, on which a final decision is expected soon. Sizewell C would be a copy of the Hinkley plant – building follow-up identical reactors achieves capital cost reductions, and setbacks at Hinkley Point C have sharpened delivery focus as an alternative funding model will likely be implemented to reduce financing costs.

Other potential nuclear sites such as Wylfa and Moorside (shelved in 2018 and 2019 respectively for financial reasons) are also not mentioned, their futures presumably also covered by the “subject to value-for-money” clause.

Small nuclear
The next generation of nuclear technology, with various designs under development worldwide are smaller, cheaper, safer Small Modular Reactors (SMRs), such as the Rolls Royce “UK SMR”.

Reactors small enough to be manufactured in factories and delivered as modules can be assembled on site in much shorter times than larger designs, which in contrast are constructed mostly on site. In so doing, the capital costs per unit (and therefore borrowing costs) could be significantly lower than current new-builds.

The plan states “up to £215 million” will be made available for SMRs, Phase 2 of which will begin next year, with anticipated delivery of units around a decade from now.

Advanced nuclear
The third proposed wave of nuclear will be the Advanced Modular Reactors (AMRs). These are truly innovative technologies, with a wide range of benefits over present designs and, like the small reactors, they are modular to keep prices down.

Crucially, advanced reactors operate at much higher temperatures – some promise in excess of 750°C compared to around 300°C in current reactors. This is important as that heat can be used in industrial processes which require high temperatures, such as ceramics, which they currently get through electrical heating or by directly burning fossil fuels. If those ceramics factories could instead use heat from AMRs placed nearby, it would reduce CO₂ emissions from industry (see chart above).

High temperatures can also be used to generate hydrogen, which the government’s plan recognises has the potential to replace natural gas in heating and eventually also in pioneering zero-emission vehicles, ships and aircraft. Most hydrogen is produced from natural gas, with the downside of generating CO₂ in the process. A carbon-free alternative involves splitting water using electricity (electrolysis), though this is rather inefficient. More efficient methods which require high temperatures are yet to achieve commercialisation, however if realised, this would make high temperature nuclear particularly useful.

The government is committing “up to £170 million” for AMR research, and specifies a target for a demonstrator plant by the early 2030s. The most promising candidate is likely a High Temperature Gas-cooled Reactor which is possible, if ambitious, over this timescale. The Chinese currently lead the way with this technology, and their version of this reactor concept is expected soon.

In summary, the plan is welcome news for the nuclear sector, even as Europe loses nuclear capacity across the continent. While it lacks some specifics, these may be detailed in the government’s upcoming Energy White Paper. The advice to government has been acknowledged, and the sums of money mentioned throughout are significant enough to really get started on the necessary research and development.

Achieving net zero is a vast undertaking, and recognising that nuclear can make a substantial contribution if properly supported is an important step towards hitting that target.

How the dirtiest power station in western Europe switched to renewable energy

Drax Biomass Conversion accelerates renewable energy by replacing coal with wood pellets, sustainable forestry feedstock, and piloting carbon capture and storage, supporting the UK grid, emissions cuts, and a net-zero pathway.

 

Key Points

Drax Biomass Conversion is Drax's shift from coal to biomass with CCS pilots to cut emissions and aid UK's net-zero.

✅ Coal units converted to biomass wood pellets

✅ Sourced from sustainable forestry residues

✅ CCS pilots target lifecycle emissions cuts

 

A power station that used to be the biggest polluter in western Europe has made a near-complete switch to renewable energy, mirroring broader shifts as Denmark's largest energy company plans to end coal by 2023.

The Drax Power Station in Yorkshire, England, used to spew out millions of tons of carbon dioxide a year by burning coal. But over the past eight years, it has overhauled its operations by converting four of its six coal-fired units to biomass. The plant's owners say it now generates 15% of the country's renewable power, as Britain recently went a full week without coal power for the first time.

The change means that just 6% of the utility's power now comes from coal, as the wider UK coal share hits record lows across the national electricity system. The ultimate goal is to stop using coal altogether.

"We've probably reduced our emissions more than any other utility in the world by transforming the way we generate power," Will Gardner, CEO of the Drax Group, told CNN Business.

Subsidies have helped finance the switch to biomass, which consists of plant and agricultural matter and is viewed as a promising substitute for coal, and utilities such as Nova Scotia Power are also increasing biomass use. Last year, Drax received £789 million ($1 billion) in government support.

 

Is biomass good for the environment?

While scientists disagree over the extent to which biomass as a fuel is environmentally friendly, and some environmentalists urge reducing biomass use amid concerns about lifecycle emissions, Drax highlights that its supplies come from from sustainably managed and growing forests.

Most of the biomass used by Drax consists of low-grade wood, sawmill residue and trees with little commercial value from the United States. The material is compressed into sawdust pellets.

Gardner says that by purchasing bits of wood not used for construction or furniture, Drax makes it more financially viable for forests to be replanted. And planting new trees helps offset biomass emissions.

Forests "absorb carbon as they're growing, once they reach maturity, they stop absorbing carbon," said Raphael Slade, a senior research fellow at Imperial College London.

But John Sterman, a professor at MIT's Sloan School of Management, says that in the short term burning wood pellets adds more carbon to the atmosphere than burning coal.

That carbon can be absorbed by new trees, but Sterman says the process can take decades.

"If you're looking at five years, [biomass is] not very good ... If you're looking at a century-long time scale, which is the sort of time scale that many foresters plan, then [biomass] can be a lot more beneficial," says Slade.

 

Carbon capture

Enter carbon capture and storage technology, which seeks to prevent CO2 emissions from entering the atmosphere and has been touted as a possible solution to the climate crisis.

Drax, for example, is developing a system to capture the carbon it produces from burning biomass. But that could be 10 years away.

 

The Coal King is racing to avoid bankruptcy

The power station is currently capturing just 1 metric ton of CO2 emissions per day. Gardner says it hopes to increase this to 10,000 metric tons per day by the mid to late 2020s.

"The technology works but scaling it up and rolling it out, and financing it, are going to be significant challenges," says Slade.

The Intergovernmental Panel on Climate Change shares this view. The group said in a 2018 report that while the potential for CO2 capture and storage was considerable, its importance in the fight against climate change would depend on financial incentives for deployment, and whether the risks of storage could be successfully managed. These include a potential CO2 pipeline break.

In the United Kingdom, the government believes that carbon capture and storage will be crucial to reaching its goal of achieving net-zero greenhouse gas emissions by 2050, even as low-carbon generation stalled in 2019 according to industry analysis.

It has committed to consulting on a market-based industrial carbon capture framework and in June awarded £26 million ($33 million) in funding for nine carbon capture, usage and storage projects, amid record coal-free generation on the British grid.

New England takes key step to 1.2 GW of Quebec hydro as Maine approves transmission line

NECEC Clean Energy Connect advances with Maine DEP permits, Hydro-Québec contracts, and rigorous transmission line mitigation, including tapered vegetation, culvert upgrades, and forest conservation, delivering low-carbon power, broadband fiber, and projected ratepayer savings.

 

Key Points

A Maine transmission project delivering Hydro-Québec power with strict DEP mitigation, lower bills, and added broadband.

✅ DEP permits mandate tapered vegetation, culvert upgrades, land conservation

✅ Hydro-Québec to supply 9.55 TWh/yr via MA contracts; bill savings 2-4%

✅ Added broadband fiber in Somerset and Franklin; local tax benefits

 

The Maine DEP reviewed the Clean Energy Connect project for more than two years, while regional interest in cross-border transmission continued to grow, before issuing permits that included additional environmental mitigation elements.

"Collectively, the requirements of the permit require an unprecedented level of environmental protection and compensatory land conservation for the construction of a transmission line in the state of Maine," DEP said in a May 11 statement.

Requirements include limits on transmission corridor width, forest preservation, culvert replacement and vegetation management projects, while broader grid programs like vehicle-to-grid integration enhance clean energy utilization across the region.

"In our original proposal we worked hard to develop a project that provided robust mitigation measures to protect the environment," NECEC Transmission CEO Thorn Dickinson said in a statement. "And through this permitting process, we now have made an exceedingly good project even better for Maine."

NECEC will be built on land owned or controlled by Central Maine Power. The 53 miles of new corridor on working forest land will use a new clearing technique for tapered vegetation, while the remainder of the project follows existing power lines.

Environmentalists said they agreed with the decision, and the mitigation measures state regulators took, noting similar momentum behind new wind investments in other parts of Canada.

"Building new ways to deliver low-carbon energy to our region is a critical piece of tackling the climate crisis," CLF Senior Attorney Phelps Turner said in a statement. "DEP was absolutely right to impose significant environmental conditions on this project and ensure that it does not harm critical wildlife areas."

Once complete, Turner said the transmission line will allow the region "to retire dirty fossil fuel plants in the coming years, which is a win for our health and our climate."

The Massachusetts Department of Public Utilities in June 2019 advanced the project by approving contracts for the state's utilities to purchase 9,554,940 MWh annually from Hydro-Quebec. Officials said the project is expected to provide approximately 2% to 4% savings on monthly energy bills.

Total net benefits to Massachusetts ratepayers over the 20-year contract, including both direct and indirect benefits, are expected to be approximately $4 billion, according to the state's estimates.

NECEC "will also deliver significant economic benefits to Maine and the region, including lower electricity prices, increased local real estate taxes and reduced energy costs with examples like battery-backed community microgrids demonstrating local resilience, expanded fiber optic cable for broadband service in Somerset and Franklin counties and funding of economic development for Western Maine," project developers said in a statement.​

Ontario to seek new wind, solar power to help ease coming electricity supply crunch

Ontario Clean Grid Plan outlines emissions-free electricity growth, renewable energy procurement, nuclear expansion at Bruce and Darlington, reduced natural gas, grid reliability, and net-zero alignment to meet IESO demand forecasts and EV manufacturing loads.

 

Key Points

A plan to expand emissions-free power via renewables and nuclear, cut natural gas use, and meet growing demand.

✅ Targets renewables, hydro, and nuclear capacity growth

✅ Aims to reduce reliance on gas for grid reliability

✅ Aligns with IESO demand forecasts and EV manufacturing loads

 

Ontario is working toward filling all of the province’s quickly growing electricity needs with emissions-free sources, including a plan to secure new renewable generation and clean power options, but isn’t quite ready to commit to a moratorium on natural gas.

Energy Minister Todd Smith announced Monday a plan to address growing energy needs for 2030 to 2050 — the Independent Electricity System Operator projects Ontario’s electricity demand could double by mid-century — and next steps involve looking for new wind, solar and hydroelectric power.

“While we may not need to start building today, government and those in the energy sector need to start planning immediately, so we have new clean, zero-emissions projects ready to go when we need them,” Smith said in Windsor, Ont.

The strategy also includes two nuclear projects announced last week — a new large-scale nuclear plant at Bruce Power on the shore of Lake Huron and three new small modular reactors at the site of the Darlington nuclear plant east of Toronto.

Those projects, enough to power six million homes, will help Ontario end its reliance on natural gas to generate electricity, said Smith, but committing to a natural gas moratorium in 2027 and eliminating natural gas by 2050 is contingent on the federal government helping to speed up the new nuclear facilities.

“Today’s report, the Powering Ontario’s Growth plan, commits us to working towards a 100 per cent clean grid,” Smith said in an interview.

“Hopefully the federal government can get on board with our intentions to build this clean generation as quickly as possible … That will put us in a much better position to use our natural gas facilities less in the future, if we can get those new projects online.”

The IESO has said that natural gas is required to ensure supply and stability in the short to medium term, as Ontario works on balancing demand and emissions across the grid, but that it will also increase greenhouse gas emissions from the electricity sector.

The province is expected to face increased demand for electricity from expanded electric vehicle use and manufacturing in the coming years, even as a $400-billion cost estimate for greening the grid is debated.

Keith Brooks, programs director for Environmental Defence, said the provincial plan could have been much more robust, containing firm timelines and commitments.

“This plan does not commit to getting emissions out of the system,” he said.

“It doesn’t commit to net zero, doesn’t set a timeline for a net zero goal or have any projection around emissions from Ontario’s electricity sector going forward. In fact, it’s not really a plan. It doesn’t set out any real goals and it doesn’t it doesn’t project what Ontario’s supply mix might look like.”

The Canadian Climate Institute applauded the plan’s focus on reducing reliance on gas-fired generation and emphasizing non-emitting generation, but also said there are still some question marks.

“The plan is silent on whether the province intends to construct new gas-fired generation facilities,” even as new gas plant expansions are proposed, senior research director Jason Dion wrote in a statement.

“The province should avoid building new gas plants since cost-effective alternatives are available, and such facilities are likely to end up as stranded assets. The province’s timeline for reaching net zero generation is also unclear. Canada and other G7 countries have set a target for 2035, something Ontario will need to address if it wants to remain competitive.”
