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.

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.

EPA Wastewater Rule Rollback signals a move to rewrite 2015 Clean Water Act guidelines for coal-fired power plants, easing wastewater rules as heavy metals, mercury, lead, arsenic, and selenium threaten rivers, lakes, public health.

Key Points

A planned EPA rewrite of 2015 wastewater limits for coal plants, weakening protections against toxic heavy metals.

✅ Targets 2015 Clean Water Act wastewater guidelines

✅ Affects coal-fired steam electric power plants

✅ Raises risks from mercury, lead, arsenic, selenium

The Environmental Protection Agency says it plans to scrap an Obama-era measure limiting water pollution from coal-fired power plants, mirroring moves to replace the Clean Power Plan elsewhere in power-sector policy.

A letter from EPA Administrator Scott Pruitt released Monday as part of a legal appeal and amid a broader rewrite of NEPA rules said he will seek to revise the 2015 guidelines mandating increased treatment for wastewater from steam electric power-generating plants.

Acting at the behest of energy groups and electric utilities who opposed the stricter standards, Pruitt first moved in April to delay implementation of the new guidelines. The wastewater flushed from the coal-fired plants into rivers and lakes typically contains traces of such highly toxic heavy metals as lead, arsenic, mercury and selenium.

“After carefully considering your petitions, I have decided that it is appropriate and in the public interest to conduct a rulemaking to potentially revise (the regulations),” Pruitt wrote in the letter addressed to the pro-industry Utility Water Act Group and the U.S. Small Business Administration.

Pruitt’s letter, dated Friday, was filed Monday with the Fifth Circuit U. S. Court of Appeals in New Orleans, which is hearing legal challenges of the wastewater rule. With Pruitt now moving to rewrite the standards, EPA has asked to court to freeze the legal fight.

While that process moves ahead, EPA’s existing guidelines from 1982 remian in effect. Those standards were set when far less was known about the detrimental impacts of even tiny levels of heavy metals on human health and aquatic life.

“Power plants are by far the largest offenders when it comes to dumping deadly toxics into our lakes and rivers,” said Thomas Cmar, a lawyer for the legal advocacy group Earthjustice. “It’s hard to believe that our government officials right now are so beholden to big business that they are willing to let power plants continue to dump lead, mercury, chromium and other dangerous chemicals into our water supply.”

EPA estimates that the 2015 rule, if implemented, would reduce power plant pollution, consistent with new pollution limits proposed for coal and gas plants, by about 1.4 billion pounds a year. Only about 12 per cent of the nation’s steam electric power plants would have to make new investments to meet the higher standards, according to the agency.

Utilities would need to spend about $480 million on new wastewater treatment systems, resulting in about $500 million in estimated public benefits, such as fewer incidents of cancer and childhood developmental defects.

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.

Renewable Energy Market Reform aligns solar and wind with modern grid pricing, tackling intermittency via batteries and demand response, stabilizing wholesale power prices, and enabling capacity markets to finance flexible supply for deep decarbonization.

Key Points

A market overhaul that integrates variable renewables, funds flexibility, and stabilizes grids as solar and wind grow.

✅ Dynamic pricing rewards flexibility and demand response

✅ Capacity markets finance reliability during intermittency

✅ Smart grids, storage, HV lines balance variable supply

ALMOST 150 years after photovoltaic cells and wind turbines were invented, they still generate only 7% of the world’s electricity. Yet something remarkable is happening. From being peripheral to the energy system just over a decade ago, they are now growing faster than any other energy source and their falling costs are making them competitive with fossil fuels. BP, an oil firm, expects renewables to account for half of the growth in global energy supply over the next 20 years. It is no longer far-fetched to think that the world is entering an era of clean, unlimited and cheap, abundant electricity for all. About time, too. 

There is a $20trn hitch, though. To get from here to there requires huge amounts of investment over the next few decades, to replace old smog-belching power plants and to upgrade the pylons and wires that bring electricity to consumers. Normally investors like putting their money into electricity because it offers reliable returns. Yet green energy has a dirty secret. The more it is deployed, the more it lowers the price of power from any source. That makes it hard to manage the transition to a carbon-free future, during which many generating technologies, clean and dirty, need to remain profitable if the lights are to stay on. Unless the market is fixed, subsidies to the industry will only grow.

Policymakers are already seeing this inconvenient truth as a reason to put the brakes on renewable energy. In parts of Europe and China, investment in renewables is slowing as subsidies are cut back, even as Europe’s electricity demand continues to rise. However, the solution is not less wind and solar. It is to rethink how the world prices clean energy in order to make better use of it.

Shock to the system

At its heart, the problem is that government-supported renewable energy has been imposed on a market designed in a different era. For much of the 20th century, electricity was made and moved by vertically integrated, state-controlled monopolies. From the 1980s onwards, many of these were broken up, privatised and liberalised, so that market forces could determine where best to invest. Today only about 6% of electricity users get their power from monopolies. Yet everywhere the pressure to decarbonise power supply has brought the state creeping back into markets. This is disruptive for three reasons. The first is the subsidy system itself. The other two are inherent to the nature of wind and solar: their intermittency and their very low running costs. All three help explain why power prices are low and public subsidies are addictive.

First, the splurge of public subsidy, of about $800bn since 2008, has distorted the market. It came about for noble reasons—to counter climate change and prime the pump for new, costly technologies, including wind turbines and solar panels. But subsidies hit just as electricity consumption in the rich world was stagnating because of growing energy efficiency and the financial crisis. The result was a glut of power-generating capacity that has slashed the revenues utilities earn from wholesale power markets and hence deterred investment.

Second, green power is intermittent. The vagaries of wind and sun—especially in countries without favourable weather—mean that turbines and solar panels generate electricity only part of the time. To keep power flowing, the system relies on conventional power plants, such as coal, gas or nuclear, to kick in when renewables falter. But because they are idle for long periods, they find it harder to attract private investors. So, to keep the lights on, they require public funds.

Everyone is affected by a third factor: renewable energy has negligible or zero marginal running costs—because the wind and the sun are free. In a market that prefers energy produced at the lowest short-term cost, wind and solar take business from providers that are more expensive to run, such as coal plants, depressing wholesale electricity prices, and hence revenues for all.

Get smart

The higher the penetration of renewables, the worse these problems get—especially in saturated markets. In Europe, which was first to feel the effects, utilities have suffered a “lost decade” of falling returns, stranded assets and corporate disruption. Last year, Germany’s two biggest electricity providers, E.ON and RWE, both split in two. In renewable-rich parts of America, power providers struggle to find investors for new plants, reflecting U.S. grid challenges that slow a full transition. Places with an abundance of wind, such as China, are curtailing wind farms to keep coal plants in business.

The corollary is that the electricity system is being re-regulated as investment goes chiefly to areas that benefit from public support. Paradoxically, that means the more states support renewables, the more they pay for conventional power plants, too, using “capacity payments” to alleviate intermittency. In effect, politicians rather than markets are once again deciding how to avoid blackouts. They often make mistakes: Germany’s support for cheap, dirty lignite caused emissions to rise, notwithstanding huge subsidies for renewables. Without a new approach the renewables revolution will stall.

The good news is that new technology can help fix the problem.  Digitalisation, smart meters and batteries are enabling companies and households to smooth out their demand—by doing some energy-intensive work at night, for example. This helps to cope with intermittent supply. Small, modular power plants, which are easy to flex up or down, are becoming more popular, as are high-voltage grids that can move excess power around the network more efficiently, aligning with common goals for electricity networks worldwide.

The bigger task is to redesign power markets to reflect the new need for flexible supply and demand. They should adjust prices more frequently, to reflect the fluctuations of the weather. At times of extreme scarcity, a high fixed price could kick in to prevent blackouts. Markets should reward those willing to use less electricity to balance the grid, just as they reward those who generate more of it. Bills could be structured to be higher or lower depending how strongly a customer wanted guaranteed power all the time—a bit like an insurance policy. In short, policymakers should be clear they have a problem and that the cause is not renewable energy, but the out-of-date system of electricity pricing. Then they should fix it.

Israel Coal Reduction accelerates the energy transition, cutting coal use in electricity production by 30% as IEC shifts to natural gas, retires Hadera units, and targets a 2030 phase-out to lower emissions.

Key Points

Plan to cut coal power by 30%, retire IEC units, and end coal by 2030, shifting electricity generation to natural gas.

✅ 30% immediate cut in coal use for electricity by IEC

✅ Hadera units scheduled for retirement and gas replacement by 2022

✅ Complete phase-out of coal and gasoil in power by 2030

Israel's Energy and Water and Environmental Protection Ministers have ordered an immediate 30% reduction in coal use for electricity production by state utility Israel Electric Corporation as the country increases its dependence on domestic natural gas.

IEC, which operates four coal power plants with a total capacity of 4,850 MW and imports thermal coal from Australia, Colombia, Russia and South Africa, has been planning, as part of the decision to reduce coal use, to shut one of its coal plants during autumn 2018, when demand is lowest.

Israel has already decided to shut the four units of the oldest coal power plant at Hadera by 2022, echoing Britain's coal-free week milestones, and replace the capacity with gas plants.

"By 2030 Israel will completely stop the use of coal and gasoil in electricity production," minister Yuval Steinmetz said.

Coal consumption peaked in 2012 at 14 million mt and has declined steadily, aligning with global trends where renewables poised to eclipse coal in power generation, with the coming on line of Israel's huge Tamar offshore gas field in 2013.

In 2015 coal accounted for more than 50% of electricity production, even as German renewables outpaced coal in generation across that market. Coal's share would decline to less than 30% under the latest decision.

Israel's coal consumption in 2016 totaled 8.7 million mt, as India rationed coal supplies amid surging demand, and was due to decline to 8 million mt last year.

Three years ago, the ministers ordered a 15% reduction in coal use, while Germany's coal generation share remained significant, and the following year a further 5% cut was added.
