Middle Georgia could be home to the state's first new coal-fired power plant in two decades if state environmental officials approve a $2.1 billion project in Washington County.

In January, POWER4Georgians, a consortium of 10 electric cooperatives, applied for environmental permits to build and operate the proposed Plant Washington. It would generate about 850 megawatts of power a day on a 1,200-acre site about eight miles north of Sandersville.

Another new coal-fired power plant is also planned west of Albany by a different company, but that project is mired in court. As coal-fired power faces increasing opposition for its contributions to smog, soot and global warming, the Plant Washington proposal is being fought by environmental groups.

"I can't even tell you how it took the breath out of me to hear they were looking to build a new coal plant on the Oconee River," said Deborah Sheppard, executive director of the Altamaha Riverkeeper group.

"As long as our state and country continue to eek electricity through new plants, it will only increase the demand for more new plants, and that will only increase stresses on our water and air."

Sandersville Mayor Jimmy Evans said locals have questioned the effect of truck and rail traffic on neighbors and impacts to the groundwater table, but they seem to generally support the effort.

The plant, to be located on former farmland with few immediate neighbors, will bring about130 permanent jobs and a substantial but as-yet-undetermined boost to the county tax base. Local electricity provider Washington EMC is one of the 10 cooperatives that teamed to create POWER4Georgians, which would own the plant.

The cooperatives would sell the electricity. Other Middle Georgia partners include Central Georgia EMC and Upson EMC.

But some of the biggest players, such as Cobb EMC, are in fast-growing areas outside the region. POWER4Georgians maintains that without the plant, customers would soon have to pay perhaps twice as much for electricity, and the state would experience power shortages.

Most of the cooperatives had contracts with private utilities such as Georgia Power to provide some of their electricity. These contracts are expiring soon and cannot be renewed at affordable prices, said Dean Alford, whose Conyers company, Allied Energ Services, is the primary developer of the plant.

Oglethorpe Power was created by the state's electricity cooperatives in 1974 to deal with the same problem. But Oglethorpe has its plate full with the effort to add two nuclear reactors to Plant Vogtle, a joint project with Georgia Power and others.

Alford said some cooperatives can't wait.

By 2015, Alford said, growing population will mean the partners in POWER4Georgians need one-third more base power capacity than they have now. Critics say power companies should focus on energy efficiency and developing "green" power sources such as solar energy.

Alford said POWER4Georgians is involved in both these efforts, but "there's just no way around needing new generation."

POWER4Georgians needs at least six environmental permits for the plant: an air pollution permit, groundwater and surface water withdrawal permits, a water discharge permit for used water that goes back into the Oconee River, a permit for the storm water running off from the plant, and a permit for storing the solid waste such as gypsum and fly ash generated by the plant.

The state Environmental Protection Division is talking with the company and its experts. After satisfying any concerns, the EPD would then issue draft permits and let people comment on them. Public meetings and hearings must be held during this process.

Jack Capp, permitting manager for the EPD's air branch, said draft permits could be issued by the end of the year. Plant developers already held a public meeting in Sandersville days after filing the permit applications, and Alford has been meeting with community groups since then, he said.

New power plants are required to install the "best available pollution control technology" to limit air pollution.

Plant Washington is proposed to be the first in the state installed with wet scrubbers and other advances.

Power plants are some of the biggest contributors to ground-level ozone, the primary component of smog, and to fine particle pollution, such as soot that can be absorbed deep in the lungs. Both types cause heart and lung problems.

Macon is in a federal nonattainment zone for having dangerous levels of fine particle pollution, and it is expected to fall back into nonattainment for its ozone pollution under new federal rules. (Athens and Augusta, also not far from Sandersville, are also expected to fail the new ozone standard.) Scientists and regulators have identified Georgia Power's nearby Plant Scherer, the largest coal-fired power plant in the country, as one of the prime culprits for Macon's air pollution.

Washington County and neighboring Wilkinson County already struggle with unsafe levels of fine particle pollution. They have not yet been designated a nonattainment zone, but without improvements they probably will be, state regulators have said.

Evans said he feels comfortable that the new coal-fired plant won't put the county in jeopardy for nonattainment.

Alford said the plant is being designed to release zero measurable fine particles, and its technology will make ozone contributions far less than those of nearby power plants like Scherer. Capp said the EPD can't approve the plant if it will cause or contribute to violations of a national air standard.

That means it can't diminish a county's air quality enough to put the area in a nonattainment zone, and it can't contribute significantly to air pollution in an existing nonattainment area. However, there is a threshold for allowing some additional pollution, he said.

POWER4Georgians must provide computer modeling showing the effect of its air pollution on a broad area, and the state will do some of its own modeling, Capp said. The company has not yet specifically addressed its effects on Macon's air quality, Capp said. Alford said POWER4Georgians is not proposing a larger plant because that would require much more work to reduce harm to air and water.

"And I can assure you this will not be expanded in the future," he said.

Coal-fired power plants also emit mercury, which eventually accumulates in fish tissue. As a neurotoxin, mercury can damage fetuses and cause developmental problems in children.

Chandra Brown, the Ogeechee Riverkeeper, said the state already warns the public to limit consumption of fish from the Ogeechee River because of its mercury levels. "Any addition of mercury is just unacceptable," she said.

Like all coal-fired power plants, Plant Washington would use large amounts of water for its cooling towers. But POWER4Georgians' plan is unusual for its partial reliance on groundwater, as well as a 30-mile pipeline from the plant to its primary water source.

The plant is requesting to use 16 million gallons of water a day from the Oconee River.

Alford said the distance prevents any harm to wetlands and puts it near a major electricity transmission line.

Sheppard, with the Altamaha Riverkeeper, said the Oconee River already is under major stress from development in the Athens area, and it receives significant industrial pollution downstream. The less water in the river, the less there is to dilute the pollution.

"Is it fair to be using water in the Oconee to create energy for north Cobb County?" Sheppard asked. "There's serious equity issues here." However, Alford noted that at least all the power generated by Plant Washington would be used in Georgia - unlike power from some of the larger Georgia Power plants or the other proposed new coal-fired plant, Plant Longleaf.

During times when the Oconee River is low, POWER4Georgians wants approval to withdraw 16 million gallons a day from 16 ground water wells. Wells would be located at intervals along the plant's pipeline to the river and would tap into the Cretaceous aquifer, Alford said.

Having multiple wells reduces the impact on the water table at each site, said Bill Frechette, coordinator for the EPD groundwater permitting unit. All public water systems in Washington County - including the more than 6,000 households in Sandersville - rely on the same aquifer, and rural residents get their water from private wells, Evans said.

But he said the area has not experienced water shortages during the current drought.

"It's true the aquifer contains a lot of water," Frechette said. "On the other hand, there are a significant amount of users in Washington and Wilkinson counties and also the kaolin operations. We will be concerned about impacts on other users."

Alford said Plant Washington would probably rely on groundwater 40 percent of the time. He said the company's analysis shows this would have a negligible effect on the water table - but if anyone's well went dry, POWER4Georgians would replace it.

Frechette said that if the groundwater permit is granted, the plant will easily be among the top 25 groundwater users out of the 475 permitted in the state.

Alford said the company will augment its water supply by reusing storm water at the plant and reclaiming 4 million to 6 million gallons of water a day from local kaolin mines.

Brown praised the effort to use kaolin wastewater but voiced some questions about its effects. She noted that the state doesn't regulate the use of water in kaolin mining.

"We don't know anything about how much there is being used and what the impacts would be on the streams if that water goes somewhere else," she said. Alford said POWER4Georgians has been monitoring kaolin water use for almost a year to determine how much would be available for the power plant.

He declined to say which kaolin companies have been involved. The plant would return a million to 4 million gallons of water to the Oconee River daily, Alford said.

The EPD has already received comments from some groups about the proposed plants, most of them urging denial of the permits. Rick and Jennifer Johnson, Washington County property owners who live in Big Canoe, in north Georgia, wrote that "Washington County does not need a new source of air pollution.... We do not need another contributor to asthma cases, chronic bronchitis a d other health problems."

Greenlaw, a firm of environmental advocacy lawyers, filed comments on behalf of 15 environmental organizations, saying POWER4Georgians has failed to sufficiently analyze the health risks of the plant.

"It's the worst modeling our experts have ever seen," said Justine Thompson, executive director of Greenlaw. Greenlaw also has appealed permits for the proposed Plant Longleaf.

Some environmental groups contend that the state also should limit the amount of carbon dioxide released by the new plant. The federal government doesn't regulate carbon dioxide, the primary "greenhouse gas" responsible for global warming, although Congress is now debating legislation that would change that. Thompson said if both Plant Washington and Plant Longleaf are approved by the state, they will contribute carbon dioxide equivalent to driving 2.5 million new cars about 12,000 miles annually.

According to the POWER4Georgians Web site, Plant Washington will require less than two-thirds the amount of coal and emit less than two-thirds the amount of carbon dioxide as traditional coal-fired power plants.

Electricity prices in Germany nearly doubled in a year

Germany Energy Price Hikes are driving electricity tariffs, gas prices, and heating costs higher as wholesale markets surge after the Ukraine invasion; households face inflationary pressure despite relief measures and a renewables levy cut.

 

Key Points

Germany Energy Price Hikes reflect surging power and gas tariffs from wholesale spikes, prompting relief measures.

✅ Electricity tariffs to rise 19.5% in Apr-Jun

✅ Gas tariffs up 42.3%; heating and fuel costs soar

✅ Renewables levy ends July; saves €6.6 billion yearly

 

Record prices for electricity and gas in Germany will continue to rise in the coming months, the dpa agency, citing estimates from the consumer portal Verivox.

According to him, electricity suppliers and local utilities, in whose area of ​​responsibility there are 13 million households, made an announcement of tariff increases in April, May and June by 19.5%. Gas tariffs increased by an average of 42.3%.

According to Verivox, electricity prices in Germany have approximately doubled over the year - a pattern seen as European electricity prices rose more than double the EU average - if previously a household with a consumption of 4,000 kWh paid 1,171 euros a year, now the amount has risen to 1,737 euros. Gas prices have risen even more, though European gas prices later returned to pre-Ukraine war levels: last year, a household with a consumption of 20,000 kWh paid 1,184 euros in annual terms, and now it is 2,787 euros. 

Energy costs for the average German household are 52 percent higher than a year ago, adding to EU inflation pressures, according to energy contract sales website Check24. In a press release, the company said the wholesale electricity price was at €122.93 per megawatt-hour in February 2022, compared to €49 this time last year, while in the United States US electricity prices climbed at the fastest pace in 41 years. In addition, electricity prices on the power exchange haven been rising rapidly since Russian troops invaded Ukraine, comparison portal Strom Report said. Costs for heating rose the most, triggered by the high gas price (105 euros per megawatt-hour on the wholesale market) and around 100 USD per barrel of oil – its highest price since 2014. Driving also became more expensive with costs for petrol up 25 percent and diesel 30 percent, Check24 said.

The German government has decided on relief measures for low-income households, including a 200 billion euro energy shield, in response to high consumer energy costs. In July, it will abolish the renewables levy on the power price, saving consumers around €6.6 billion annually. In a reform proposal released this week, the ministry for economy and climate also detailed how it will legally oblige power suppliers to reduce their power bills when the levy is abolished.

Parisians vote to ban rental e-scooters from French capital by huge margin

Paris E-Scooter Ban: Voters back ending rental scooters after a public consultation, citing road safety, pedestrian clutter, and urban mobility concerns; impacts Lime, Dott, and Tier operations across the capital.

 

Key Points

A citywide prohibition on rental e-scooters, approved by voters, to improve safety, order, and walkability.

✅ Non-binding vote shows about 90% support citywide.

✅ About 15,000 rental scooters from Lime, Dott, Tier affected.

✅ Cites 2022 injuries, fatalities, and sidewalk clutter.

 

Parisians have voted to rid the streets of the French capital of rental electric scooters, with an overwhelming 90% of votes cast supporting a ban, official results show, amid a wider debate over the limits of the electric-car revolution and its real-world impact.

Paris was a pioneer when it introduced e-scooters, or trottinettes, in 2018 as the city’s authorities sought to promote non-polluting forms of urban transport, amid record EV adoption in France across the country.

But as the two-wheeled vehicles grew in popularity, especially among young people, and, with similar safety concerns prompting the TTC winter ban on lithium-ion e-bikes and scooters in Toronto, so did the number of accidents: in 2022, three people died and 459 were injured in e-scooter accidents in Paris.

In what was billed as a “public consultation” voters were asked: “For or against self-service scooters?”

Twenty-one polling stations were set up across the city and were open until 7pm local time. Although 1.6 million people are eligible to vote, turnout is expected to be low.

The ban won between 85.77% and 91.77% of the votes in the 20 Paris districts that published results, according to the City of Paris website on what was billed as a rare “public consultation” and prompted long queues at ballot boxes around the city. The vote was non-binding but city authorities have vowed to follow the result, echoing Britain's transport rethink that questions simple fixes.

Paris’s socialist mayor, Anne Hidalgo, has promoted cycling and bike-sharing but supported a ban on e-scooters, as France rolls out new EV incentive rules affecting Chinese manufacturers.

In an interview with Agence France-Presses last week, Hidalgo said “self-service scooters are the source of tension and worry” for Parisians and that a ban would “reduce nuisance” in public spaces, with broader benefits for air quality noted in EV use linked to fewer asthma ER visits in recent studies as well.

Paris has almost 15,000 e-scooters across its streets, operated by companies including Lime, Dott and Tier. Detractors argue that e-scooter users disrespect the rules of the road and regularly flout a ban on riding on pavements, even as France moves to discourage Chinese EV purchases to shape the broader mobility market. The vehicles are also often haphazardly parked or thrown into the River Seine.

In June 2021, a 31-year-old Italian woman was killed after being hit by an e-scooter with two passengers onboard while walking along the Seine.

“Scooters have become my biggest enemy. I’m scared of them,” Suzon Lambert, a 50-year-old teacher from Paris, told AFP. “Paris has become a sort of anarchy. There’s no space any more for pedestrians.”


Another Parisian told BFMTV: “It’s dangerous, and people use them badly. I’m fed up.”

Julian Sezgin, aged 15, said he often saw groups of two or three teenagers on e-scooters zooming past cars on busy roads. “I avoid going on e-scooters and prefer e-bikes as, in my opinion, they are safer and more efficient,” he told the Guardian.

Bianca Sclavi, an Italian who has lived in Paris for years, said the scooters go “too fast” and should be mechanically limited so they go slower. “They are dangerous because they zip in and out of traffic,” she said. “However, it is not as bad as when they first arrived … the most dangerous are the drunk tourists!”

Share of coal in UK's electricity system falls to record lows

UK Coal Phase-Out marks record-low coal generation as the UK grid shifts to renewable power, wind farms, and a net zero trajectory, slashing carbon emissions and supporting cleaner EV charging across the electricity system.

 

Key Points

UK Coal Phase-Out ends coal-fired electricity nationwide, powered by renewables and net zero policy to cut grid carbon.

✅ Coal's Q2 share fell to 0.7%, a record low

✅ Renewables up 12% with Beatrice wind farm

✅ EV charging grows cleaner as grid decarbonizes

 

The share of coal in the UK’s electricity system has fallen to record lows in recent months, alongside a coal-free power record, according to government data.

The figures show electricity generated by the UK’s most polluting power plants made up an average of 0.7% of the total in the second quarter of this year, a shift underway since wind first outpaced coal in 2016 across the UK. The amount of coal used to power the electricity grid fell by almost two-thirds compared with the same months last year.

A government spokesperson said coal-generated energy “will soon be a distant memory” as the UK moves towards becoming a net zero emissions economy, despite signs that low-carbon generation stalled in 2019 in some analyses.

“This new record low is a result of our world-leading low-carbon energy industry, which provided more than half of our energy last year and continues to go from strength to strength as we aim to end our contribution to climate change entirely by 2050,” the spokesperson said.

The UK electricity market is on track to end coal power after 142 years by the government’s target date of 2025.

This year three major energy companies have announced plans to close coal-fired power plants in the UK, which would leave only four remaining after the coming winter, ahead of the last coal power station going offline nationwide.

RWE said this month it would close the Aberthaw B power station in south Wales, its last UK coal plant, after the winter. SSE will close the Fiddler’s Ferry plant near Warrington, Cheshire, in March 2020, and EDF Energy will shutter the Cottam coal plant in September.

So far this year the UK has gone more than 3,000 hours without using coal for power, including a full week without coal earlier in the year – nearly five times more than the whole of 2017.

Meanwhile, the government’s data shows that renewable energy climbed by 12% from the second quarter of last year, boosted by the startup of the Beatrice windfarm in the Moray Firth in Scotland, and the UK leading the G20 in wind power share in recent assessments.

The cleaner power system could accelerate carbon savings from the UK’s roads, too, as more drivers opt for electric vehicles. A study by Imperial College London for the energy company Drax found that the UK’s increasingly low-carbon energy system meant electric cars were a greener option even when taking into account the carbon emissions produced by making car batteries.

Dr Iain Staffell, of Imperial College London, said: “An electric vehicle in the UK simply cannot be more polluting than its petrol or diesel equivalent – even when taking into account the upfront carbon cost of manufacturing their batteries. Any EV bought today could be emitting just a tenth of what a petrol car would in as little as five years’ time, as the electricity it uses to charge comes from an increasingly low-carbon mix.”

Hydro-Québec to Invest $750 Million in Carillon Generating Station

Hydro-Québec Carillon Refurbishment delivers a $750M hydropower modernization, replacing six turbines and upgrading civil works, water passageways, and grid equipment to extend run-of-river, renewable energy output for peak demand near Montréal.

 

Key Points

A $750M project replacing six units and upgrading civil, water and electrical systems to supply power for 50 years.

✅ Replaces six generating units with Andritz turbines.

✅ Upgrades civil works, water passageways, and electrical gear.

✅ Extends run-of-river output for 50 years; boosts peak supply.

 

Hydro-Québec will invest $750 million to refurbish its Carillon generating station with a major powerhouse upgrade that will mainly replace six generating units. The investment also covers the cost of civil engineering work, including making adjustments to water passageways, upgrading electrical equipment and replacing the station roof. Work will start in 2021, aligning with Hydro-Québec's capacity expansion plans for 2021, and continue until 2027.

Carillon generating station is a run-of-river power plant consisting of 14 generating units with a total installed capacity of 753 MW. Built in the early 1960s, it is a key part of Hydro-Québec's hydroelectric generating fleet, which includes the La Romaine complex as well. The station is close to the greater Montréal area and feeds power into the grid to support industrial demand growth during peak consumption periods.

The selected supplier, turbine manufacturer Andritz, has been asked to maximize the project's economic spinoffs in Québec, as Canada continues investing in new turbines across the country to modernize assets. Once the work is completed, the new generating units will be able to provide clean, renewable energy, supporting Hydro-Québec's strategy to reduce fossil fuel reliance for the next 50 years.

"Carillon generating station is a symbol of our hydroelectric development and plays a strategic role in our production fleet. However, most of the generating units' main components date back to the station's original construction from 1959 to 1962. Hydropower generating stations have long service lives - with this refurbishment, Carillon will be producing clean renewable energy for decades to come." said David Murray, Chief Innovation Officer and President, Hydro-Québec Production.

"In light of today's economic situation, this is an important announcement that clearly reaffirms Hydro-Québec's role in relaunching Québec's economy and strengthening interprovincial electricity partnerships that open new markets. Over 600,000 hours of work will be required for everything from the engineering work to component assembly, creating many new high-quality skilled jobs for Québec industries."

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.
