EPA moves to rewrite limits for coal power plant wastewater

Vehicle-to-Grid (V2G) enables bidirectional charging, letting EV batteries supply smart grid services to large buildings, support renewable energy integration, reduce battery degradation, and optimize demand response for efficient, resilient power management.

Key Points

Vehicle-to-Grid (V2G) is bidirectional EV charging that feeds the grid and buildings while protecting battery health.

✅ Uses idle EVs to power buildings and support renewables

✅ Smart algorithms minimize lithium-ion battery degradation

✅ Provides grid services, demand response, and peak shaving

Stored energy from electric vehicles (EVs) can be used to power large buildings -- creating new possibilities for the future of smart, renewable energy -- thanks to ground-breaking battery research from WMG at the University of Warwick.

Dr Kotub Uddin, with colleagues from WMG's Energy and Electrical Systems group and Jaguar Land Rover, has demonstrated that vehicle-to-grid (V2G) technology can be intelligently utilised to take enough energy from idle EV batteries to be pumped into the grid and power buildings -- without damaging the batteries.

This new research into the potentials of V2G shows that it could actually improve vehicle battery life by around ten percent over a year.

For two years, Dr Uddin's team analysed some of the world's most advanced lithium ion batteries used in commercially available EVs -- and created one of the most accurate battery degradation models existing in the public domain -- to predict battery capacity and power fade over time, under various ageing acceleration factors -- including temperature, state of charge, current and depth of discharge.

Using this validated degradation model, Dr Uddin developed a 'smart grid' algorithm, which supports grid coordination and intelligently calculates how much energy a vehicle requires to carry out daily journeys, and -- crucially -- how much energy can be taken from its battery without negatively affecting it, or even improving its longevity.

The researchers used their 'smart grid' algorithm to see if they could power WMG's International Digital Laboratory -- a large, busy building which contains a 100-seater auditorium, two electrical laboratories, teaching laboratories, meeting rooms, and houses approximately 360 staff -- with vehicle-to-building charging from EVs parked on the University of Warwick campus.

They worked out that the number of EVs parked on the campus (around 2.1% of cars, in line with the UK market share of EVs) could spare the energy to power this building, acting as capacity on wheels for electricity networks -- and that in doing so, capacity fade in participant EV batteries would be reduced by up to 9.1%, and power fade by up to 12.1% over a year.

It has previously been thought that extracting energy from EVs with V2G technology causes their lithium ion batteries to degrade more rapidly.

Dr Uddin's group (along with collaborators from Jaguar Land Rover) have proved, however, that battery degradation is more complex -- and this complexity, in operation, can be exploited to improve a battery's lifetime.

Given that battery degradation is dependent on calendar age, capacity throughput, temperature, state of charge, current and depth of discharge, V2G is an effective tool that can be used to optimise a battery's conditions such that degradation is minimised. Hence, taking excess energy from an idle EV to power the grid actually keeps the battery healthier for longer.

Dr Uddin commented on the research:

"These findings reinforce the attractiveness of vehicle-to-grid technologies to automotive Original Equipment Manufacturers: not only is vehicle-to-grid an effective solution for grid support -- and subsequently a tidy revenue stream -- but we have shown that there is a real possibility of extending the lifetime of traction batteries in tandem.

"The results are also appealing to policy makers interested in grid decarbonisation and addressing grid challenges from rising EVs across power systems."

The research, 'On the possibility of extending the lifetime of lithium-ion batteries through optimal V2G facilitated by an integrated vehicle and smart-grid system' is published in Energy.

It was funded by the Engineering and Physical Sciences Research Council and the WMG centre High Value Manufacturing Catapult, in partnership with Jaguar Land Rover.

TransWest Express Power Line will deliver Wyoming wind energy to California via a 730-mile high-voltage corridor, integrating 3,000 MW from the Chokecherry and Sierra Madre project to strengthen the Western grid and decarbonization goals.

Key Points

A 730-mile line delivering up to 3,000 MW of Wyoming wind to Western states, improving clean energy reliability.

✅ 3,000 MW from Chokecherry and Sierra Madre turbines

✅ 730-mile route linking Wyoming to CA, AZ, NV markets

✅ Supports 60% by 2030, 100% by 2045 clean mandates

A conservative billionaire wants to build America's biggest wind farm in Wyoming and send the clean electricity to California.

Federal officials have approved another section of the 730-mile TransWest Express power line, in line with a renewable transmission rule aimed at speeding upgrades, which would carry energy from Philip Anschutz's Chokecherry and Sierra Madre wind farm to potential customers in California, Arizona and Nevada. The 1,000-turbine, 3,000-megawatt wind project, which has been in the works for a decade, would be built in south-central Wyoming, in one of the windiest spots in the continental U.S.

Supporters say the massive power project would help California meet its clean energy goals, in part because Wyoming winds tend to blow strong into the evening, as the sun sets over the Pacific and the Golden State's many solar farms go offline, though expanding battery storage is starting to fill that gap. Under California law, electric utilities are required to get 50% of their power from renewable sources by 2030. The state Senate passed a bill Wednesday that would raise the clean energy mandate to 60% by 2030 and 100% by 2045.

The Denver-based Anschutz Corporation hasn't inked any contracts to sell the electricity its Wyoming wind farm would generate. But company officials are confident demand will materialize by the time they're ready to build turbines. Construction of roads and other project infrastructure started last year and picked back up in April after a winter hiatus.

The developer has already spent $100 million developing the wind farm and power line, and expects to spend a combined $8 billion on the two projects.

After an extensive environmental review, the U.S. Forest Service issued a permit Wednesday for portions of the TransWest Express transmission line that would cross through 19 miles of the Uinta-Wasatch-Cache and Manti-La Sal national forests in Utah.

"It's another step forward in the process of making this line a reality, and being able to provide a path that allows California, Arizona and Nevada to access the high volumes of renewable energy supplies that are available in Wyoming," said Kara Choquette, a spokesperson for the Anschutz subsidiaries developing the power project.

Between the Forest Service approval and a Bureau of Land Management permit issued in December, the developer now has the go-ahead to build about two-thirds of the 730-mile route, Choquette said, progress that comes as the U.S. grid overhaul for renewables accelerates nationwide. Company officials are reaching out to the roughly 450 private landowners along the proposed route. They must also apply for a state permit in Wyoming, and 14 county-level permits in Wyoming, Colorado, Utah and Nevada.

But Anschutz's Chokecherry and Sierra Madre wind farm is a reminder that Trump can't stop the ongoing transition from coal to cleaner sources of energy, which is being driven largely by market forces. Solar, wind and natural gas, which burns more cleanly than coal, are now the cheapest sources of new electricity across much of the country, even as Texas grid constraints sometimes force High Plains turbines to shut down during oversupply. Utility industry executives are abandoning coal and embracing renewable energy. And the American solar industry employs more people than coal or natural gas.

States and local governments in California, New York and elsewhere have also forged ahead with policies to reduce climate emissions, including New York's largest offshore wind project recently approved. So have major companies like Apple, Facebook and Google, which have invested billions of dollars in renewable energy.

"The (Trump) administration is so out of step with reality right now. The trend is powerful, whether it's coming the cities or corporations, or from the coastal states," said Don Furman, a former utility executive who now advocates for greater sharing of renewable energy across state lines in the West.

Clean energy advocates say the 3,000-megawatt Wyoming wind farm is an especially powerful example of the economic case for renewable energy, because its proprietor is Anschutz, a longtime fossil fuel magnate and major donor to Republican politicians.

"I don't think Philip Anschutz would be putting his money here if he thought this was a bad business bet," Furman said.

The Forest Service also issued a permit Wednesday for the 416-mile Energy Gateway South power line, which would run through Wyoming, Colorado and Utah, traversing nine miles of the same national forests TransWest Express would cross. Gateway South is part of the 1,900-mile Energy Gateway transmission project being developed by Warren Buffett's PacifiCorp utility, which serves customers across six western states.

PacifiCorp officials say the $6 billion transmission project is needed to meet growing electricity demand. They've also pitched the power lines as another opportunity to transmit wind power from Wyoming to California and other coastal states. Critics, though, see Energy Gateway as costly and unnecessary — and they're worried Californians would end up paying the price through higher electricity rates.

UPS Tesla Electric Semi Order marks the largest pre-order of all-electric Class-8 big rigs, advancing sustainable freight logistics with lower total cost of ownership, expanded charging infrastructure support, and competitive range versus diesel trucks.

Key Points

UPS's purchase of 125 Tesla all-electric Class-8 semis to cut costs, emissions, and modernize long-haul freight.

✅ Largest public pre-order: 125 electric Class-8 trucks

✅ Aims lower total cost of ownership vs diesel

✅ Includes charging infrastructure consulting by Tesla

United Parcel Service Inc. said on Tuesday it is buying 125 Tesla Inc. all-electric semi-trucks, the largest order for the big rig so far, as the package delivery company expands its fleet of alternative-fuel vehicles, including options like the all-electric Transit cargo van now entering the market.

Tesla is trying to convince the trucking community it can build an affordable electric big rig with the range and cargo capacity to compete with relatively low-cost, time-tested diesel trucks. This is the largest public order of the big rig so far, Tesla said.

The Tesla trucks will cost around $200,000 each for a total order of about $25 million. UPS expects the semi-trucks, the big rigs that haul freight along America's highways, will have a lower total cost of ownership than conventional vehicles, which run about $120,000.

Tesla has received pre-orders from such major companies as Wal-Mart, fleet operator J.B. Hunt Transport Services Inc. and food service distributor Sysco Corp.

Prior to UPS, the largest single pre-order came from PepsiCo Inc, for 100 trucks. 

UPS said it has provided Tesla with real-world routing information as part of its evaluation of the vehicle's expected performance.

"As with any introductory technology for our fleet, we want to make sure it's in a position to succeed," Scott Phillippi, UPS senior director for automotive maintenance and engineering for international operations, told Reuters.

Phillippi said the 125 trucks will allow UPS to conduct a proper test of their abilities. He said the company was still determining their routes, but the semis will "primarily be in the United States." Tesla will provide consultation and support on charging infrastructure, as electric truck fleets will need a lot of power to operate at scale.

"We have high expectations and are very optimistic that this will be a good product and it will have firm support from Tesla to make it work," Phillippi said.

The UPS alternative fuel fleet already includes trucks propelled by electricity, natural gas, propane and other non-traditional fuels, and interest in electric mail trucks underscores how delivery fleets are evolving.

About 260,000 semis, or heavy-duty Class-8 trucks, are produced in North America annually, according to FTR, an industry economics research firm.

Including the UPS order, Tesla has at least 410 pre-orders in hand, according to a Reuters tally.

Navistar International Corp. and Volkswagen AG hope to launch a smaller, electric medium-duty truck by late 2019, while rival Daimler AG has delivered the first of a smaller range of electric trucks to customers in New York, and Volvo Trucks planned a complete range of electric trucks in Europe by 2021.

Tesla unveiled its semi last month, following earlier plans to reveal the truck in October, and expects the truck to be in production by 2019.

Revolution Wind Massachusetts will assemble turbine foundations in New Bedford, Fall River, or Somerset, building a local offshore wind supply chain, creating regional jobs, and leveraging pumped storage and an offshore transmission backbone.

Key Points

An offshore wind project assembling MA foundations, building a local supply chain, jobs, and peak clean power.

✅ 400 MW offshore wind; local fabrication of 1,500-ton foundations

✅ 300+ direct jobs, 600 indirect; MA crew vessel builds and operations

✅ Expandable offshore transmission; pumped storage for peak power

Deepwater Wind will assemble the wind turbine foundations for its Revolution Wind in Massachusetts, and it has identified three South Coast cities – New Bedford, Fall River and Somerset – as possible locations for this major fabrication activity, the company is announcing today.

Deepwater Wind is committed to building a local workforce and supply chain for its 400-megawatt Revolution Wind project, now under review by state and utility officials as Massachusetts advances projects like Vineyard Wind statewide.

“No company is more committed to building a local offshore wind workforce than us,” said Deepwater Wind CEO Jeffrey Grybowski. “We launched America’s offshore wind industry right here in our backyard. We know how to build offshore wind in the U.S. in the right way, and our smart approach will be the most affordable solution for the Commonwealth. This is about building a real industry that lasts.”

#google#

The construction activity will involve welding, assembly, painting, commissioning and related work for the 1,500-ton steel foundations supporting the turbine towers. This foundation-related work will create more than 300 direct jobs for local construction workers during Revolution Wind’s construction period. An additional 600 indirect and induced jobs will support this effort.

In addition, Deepwater Wind is now actively seeking proposals from Massachusetts boat builders for the construction of purpose-built crew vessels for Revolution Wind. Several dozen workers are expected to build the first of these vessels at a local boat-building facility, and another dozen workers will operate this specialty vessel over the life of Revolution Wind. (Deepwater Wind commissioned America’s only offshore wind crew vessel – Atlantic Wind Transfer’s Atlantic Pioneer – to serve the Block Island Wind Farm.)

The company will issue a formal Request for Information to local suppliers in the coming weeks. Deepwater Wind’s additional wind farms serving Massachusetts will require the construction of additional vessels, as will growth along Long Island’s South Shore in the coming years.

These commitments are in addition to Deepwater Wind’s previously-announced plans to use the New Bedford Marine Commerce Terminal for significant construction and staging operations, and to pay $500,000 per year to the New Bedford Port Authority to use the facility. During construction, the turbine marshaling activity in New Bedford is expected to support approximately 700 direct regional construction jobs.

“Deepwater Wind is building a sustainable industry on the South Coast of Massachusetts,” said Matthew Morrissey, Deepwater Wind Vice President Massachusetts. “With Revolution Wind, we are demonstrating that we can build the industry in Massachusetts while enhancing competition and keeping costs low.”

The Revolution Wind project will be built in Deepwater Wind’s federal lease site, under the BOEM lease process, southwest of Martha’s Vineyard. If approved, local construction work on Revolution Wind would begin in 2020, with the project in operations in 2023. Survey work is already underway at Deepwater Wind’s offshore lease area.

Revolution Wind will deliver “baseload” power, allowing a utility-scale renewable energy project for the first time to replace the retiring fossil fuel-fired power plants closing across the region, a transition echoed by Vineyard Wind’s first power milestones elsewhere.

Revolution Wind will be capable of delivering clean energy to Massachusetts utilities when it’s needed most, during peak hours of demand on the regional electric grid. A partnership with FirstLight Power, using its Northfield Mountain hydroelectric pumped storage in Northfield, Massachusetts, makes this peak power offering possible. This is the largest pairing of hydroelectric pumped storage and offshore wind in the world.

The Revolution Wind offshore wind farm will also be paired with a first-of-its-kind offshore transmission backbone. Deepwater Wind is partnering with National Grid Ventures on an expandable offshore transmission network that supports not just Revolution Wind, but also future offshore wind farms, as New York’s biggest offshore wind farm moves forward across the region, even if they’re built by our competitors.

This cooperation is in the best interest of Massachusetts electric customers because it will reduce the amount of electrical infrastructure needed to support the state’s 1,600 MW offshore wind goal. Instead of each subsequent developer building its own standalone cable network, other offshore wind companies could use expandable infrastructure already installed for Revolution Wind, reducing project costs and saving ratepayers money.

US Shift From Coal to Renewables accelerates as natural gas, solar, and wind power gain market share, driven by the Paris climate agreement, clean energy mandates, smart grid upgrades, and energy efficiency.

Key Points

An industry trend where power producers replace coal with natural gas, solar, and wind to meet clean energy goals.

✅ Shareholders and customers demand cleaner power portfolios

✅ Natural gas, solar, and wind outcompete coal on cost and risk

✅ Smart grid and efficiency investments reduce emissions further

President Trump once again promised to revive the U.S. coal industry when he announced his intention to withdraw the U.S. from the Paris climate agreement.

But that reversal seems as unlikely as ever as electric power producers, the biggest consumers of coal in the U.S., continue to shift to natural gas and renewable energy sources like solar and wind power. In 2016, natural gas became the leading fuel for U.S. electricity generation for the first time, responsible for 33.8% of the output, compared with 30.4% for coal, according to the U.S. Energy Information Administration, even as coal-fired generation was projected to rise in 2021 in the short term.

Nick Akins, the CEO of American Electric Power, one of the largest utilities in the U.S., says the preference for gas, renewables and energy efficiency, will only grow in response to increasing demands from shareholders and customers for cleaner energy, regardless of changes in national energy policy.

With 5.4 million customers in 11 states, AEP plans to spend $1.5 billion on renewable energy from 2017 through 2019, and $13 billion on transmission and distribution improvements, including new “smart” technologies that will make the grid more resilient and efficient, AEP says.

We spoke with Akins on Thursday, just after Trump’s announcement. The transcript is edited for length and clarity.

What do you think of Trump’s decision to pull the U.S. from the climate agreement?

I don’t think it’s unexpected. He obviously made the point that he’s willing to renegotiate or have further dialogue about it. That’s a good sign. From our perspective, we’re going to continue along the path we’re already on toward a cleaner energy economy.

AEP and the U.S. electric power industry in general have been moving away from coal in favor of natural gas and renewable energy. Will this decision by the Trump administration have any impact on that trend?

If you look at our resource plans in all of the states we serve, they are focused on renewables, natural gas and transmission, as declining returns from coal generation pressure investment choices across the industry. And big-data analytics improves the efficiency of the grid, so energy efficiency is obviously a key component, as Americans use less electricity overall.

Our carbon dioxide emissions in 2016 were 44% below 2000 levels, and that progress will continue with the additions of more renewables, energy efficiency and natural gas.

So, you don’t see coal making a comeback at AEP or other utilities?

No, I don’t think so. … You wouldn’t make a decision (to build a coal power plant) at this point because it’s heavily capital-intensive, and involves a longer-term process and risk to build. And, of course, you can add renewables that are very efficient and natural gas that’s efficient and much less expensive and risky, in terms of construction and operation.

Do you plan to close any more coal-powered plants soon? 

I suspect we’ll see some more retirements in the future, with coal and nuclear closures test just transition in many communities, and as we progress towards that cleaner energy economy, and consider the expectations of our customers and shareholders for us to mitigate risk, you’ll continue to see that happen.

But on the other hand, I want to make sure there’s an understanding that coal will remain a part of the portfolio, even though in rare cases new coal plants are still being built where options are limited, but it will be of a lesser degree because of these other resources that are available to us now that weren’t available to us just a few years ago.

Do you find yourself under more or less pressure from customers and shareholders to move to cleaner forms of energy?

I think there’s more pressure. Investors are looking for the sustainability of the company going forward and mitigation of risks … From a customer standpoint, we have some large customers interested in moving into our service territory who are looking for cleaner energy, and want to know if we’re focused on that. Some of them want to be supplied entirely by those clean sources. So, we’re clearly responding to our customers’ and our shareholders’ expectations.

What’s the solution for workers at coal mines and coal power plants who have lost their jobs?

Certainly, the skill sets of employees in mining and around machinery are transferable to other areas of manufacturing, like aerospace and defense. So, we’re really focusing on economic-development efforts in our service territories … particularly in the coal states … to bring coal miners back to work, not necessarily in coal mines but certainly (in manufacturing).

Electric Vehicle Market Growth accelerated as EV adoption hit 2 million in 2016, per IEA, led by China, Tesla momentum, policy incentives, charging infrastructure buildout, and diesel decline under Paris Agreement goals.

Key Points

EV adoption rose to 2 million in 2016, driven by policy, China, and charging buildout, yet still only 0.2% of cars.

✅ 2M EVs on roads in 2016; 60% YoY growth

✅ China led with >40% of global EV sales

✅ Policies target 30% share by 2030 via EVI

The number of electric vehicles on the road rocketed to 2 million in 2016 as the age of electric cars accelerates after being virtually non-existent just five years ago, according to the International Energy Agency.

Registered plug-in and battery-powered vehicles on roads worldwide rose 60% from the year before, according to the Global EV Outlook 2017 report from the Paris-based IEA. Despite the rapid growth, electric vehicles still represent just 0.2% of total light-duty vehicles even as U.S. EV sales continue to soar into 2024, suggesting a turning point.

“China was by far the largest electric car market, accounting for more than 40% of the electric cars sold in the world and more than double the amount sold in the United States,” the IEA wrote in the report published Wednesday. “It is undeniable that the current electric car market uptake is largely influenced by the policy environment.”

A multi government program called the Electric Vehicle Initiative on Thursday will set a goal for 30% market share for battery power cars, buses, trucks and vans by 2030, aligning with projections that driving electric cars within a decade could become commonplace, according to IEA. The 10 governments in the initiative include China, France, Germany, the UK and US.

India, which isn’t part of the group, said last month that it plans to sell only electric cars by the end of the next decade. Countries and cities are looking to electric vehicles to help tackle their air pollution problems.

In order to limit global warming to below 2 degrees Celsius (3.6 degrees Fahrenheit), the target set by the landmark Paris Agreement on climate change, the world will need 600 million electric vehicles by 2040, according to the IEA.

After struggling for consumer acceptance, Tesla Inc. has made electric vehicles cool and trendy, and is pushing into the mass market as the United States approaches a tipping point for mass adoption with the new Model 3 sedan.

Consumer interest and charging infrastructure, as well as declining demand for diesel cars in the wake of Volkswagen’s emissions scandal, has spurred massive investments in plug-in cars, and across Europe the share of electric cars grew during virus lockdown months, reinforcing this momentum. An electrical vehicle “cool factor” could spur sales to 450 million by 2035, according to BP chief economist Spencer Dale.

Volkswagen, the world’s largest automaker, plans to roll out four affordable electric vehicles in the coming years as part of a goal to sell more than 2 million battery-powered vehicles a year by 2025. Mercedes-Benz accelerated the introduction of ten new electric vehicles by three years to 2022 to take on Tesla as the dominance of the combustion engine gradually fades.
