Smart electric grids will need even smarter cybersecurity to keep them safe from would-be hackers, an energy expert said at a scientific conference recently.

"A smart grid, by connecting the power industry to the Internet, opens the door for anyone who wants to mess with the power system in the U.S.," said Dr. Stephen Holditch, a professor at the Texas A&M Energy Engineering Institute.

CenterPoint Energy, which distributes electricity to Houston-area customers regardless of retail provider, has installed more than 100,000 smart meters, and other Texas utilities are installing them as well.

The meters are a component of smart grids that use the Internet and other information technology to monitor and control generation, delivery and consumption of electricity -- allowing customers to better track their power use and improving utilities' ability to identify and fix outages.

While smart grids are heralded as potentially saving the U.S. $130 billion over the next decade, the linking of the power grid with communications systems provides potential openings for hackers, Holditch said at the annual conference of the Academy of Medicine, Engineering & Science of Texas.

The need for a secure grid was among several topics raised as Holditch presented findings of last April's Texas Energy Summit.

Others included shale gas regulation, transportation, nuclear power and renewable energy.

Developing appropriate regulations to oversee shale gas production is one of the greatest energy challenges facing Texas, Holditch said, and he prefers keeping it close to home.

"We have to have rules and regulations on how to oversee the natural gas industry, but this should be done at the state level, not at the federal level," he said.

Holditch identified possible effects on water supplies and air pollution as the most pressing issues related to natural gas drilling.

Holditch also discussed scientific discoveries that could lead to production of ethanol from natural gas, rather than corn.

Celanese Corp. has developed a technology for converting natural gas to ethanol that would be more cost effective than using corn, according to the Energy Summit report.

"The current challenge is to increase the demand for natural gas so that prices are high enough to justify resource development," the report stated.

The federal government has subsidized corn-based ethanol, which is mixed into the gasoline supply to reduce tailpipe emissions of pollutants and greenhouse gases.

"Maybe we should save the corn to eat and drink -- as bourbon," Holditch said.

Cancelling Ontario's wind project could cost over $100M, company warns

White Pines Project cancellation highlights Ontario's wind farm contract dispute in Prince Edward County, involving IESO approvals, Progressive Conservatives' legislation, potential court action, and costs to ratepayers amid green energy policy shifts.

 

Key Points

The termination effort for Ontario's White Pines wind farm contract, triggering legal, legislative, and cost disputes.

✅ Contract with IESO dates to 2009; final approval during election

✅ PCs seek legislation insulating taxpayers from litigation

✅ Cancellation could exceed $100M; cost impact on ratepayers

 

Cancelling an eastern Ontario green energy project that has been under development for nearly a decade could cost more than $100 million, the president of the company said Wednesday, warning that the dispute could be headed to the courts.

Ontario's governing Progressive Conservatives said this week that one of their first priorities during the legislature's summer sitting would be to cancel the contract for the White Pines Project in Prince Edward County.

Ian MacRae, president of WPD Canada, the company behind the project, said he was stunned by the news given that the project is weeks away from completion.

"What our lawyers are telling us is we have a completely valid contract that we've had since 2009 with the (Independent Electricity System Operator). ... There's no good reason for the government to breach that contract," he said.

The government has also not reached out to discuss the cancellation, he said. Meanwhile, construction on the site is in full swing, he said.

"Over the last couple weeks we've had an average of 100 people on site every day," he said. "The footprint of the project is 100 per cent in. So, all the access roads, the concrete for the base foundations, much of the electrical infrastructure. The sub-station is nearing completion."

The project includes nine wind turbines meant to produce enough electricity to power just over 3,000 homes annually, even as Ontario looks to build on an electricity deal with Quebec for additional supply. All of the turbines are expected to be installed over the next three weeks, with testing scheduled for the following month.

MacRae couldn't say for certain who would have to pay for the cancellation, electricity ratepayers or taxpayers.

"Somehow that money would come from IESO and it would be my assumption that would end up somehow on the ratepayers, despite legislation to lower electricity rates now in place," he said. "We just need to see what the government has in mind and who will foot the bill."

Progressive Conservative house leader Todd Smith, who represents the riding where the project is being built, said the legislation to cancel the project will also insulate taxpayers from domestic litigation over the dismantling of green energy projects.

"This is something that the people of Prince Edward County have been fighting ... for seven years," he said. "This shouldn't have come as a surprise to anybody that this was at the top of the agenda for the incoming government, which has also eyed energy independence in recent decisions."

Smith questioned why Ontario's Independent Electricity System Operator gave the final approval for the project during the spring election campaign.

"There's a lot of questions about how this ever got greenlighted in the first place," he said. "This project was granted its notice to proceed two days into the election campaign ... when (the IESO) should have been in the caretaker mode."

Terry Young, the IESO's vice president of policy, engagement and innovation, said the agency could not comment because of the pending introduction of legislation to cancel the deal, following a recent auditor-regulator dispute that drew attention to oversight.

NDP Leader Andrea Horwath said the new Tory government is behaving like the previous Liberal government by cancelling energy projects and tearing up contracts amid ongoing debates over Ontario's hydro mess and affordability. She likened the Tory plan to the Liberal gas plant scandal that saw the government relocate two plants at a substantial cost to taxpayers.

Biggest offshore windfarm to start UK supply this week

Hornsea One Offshore Wind Farm delivers first power to the UK grid, scaling renewable energy with 1.2GW capacity, giant offshore turbines, and Yorkshire coast infrastructure to replace delayed nuclear and cut fossil fuel emissions.

 

Key Points

Hornsea One Offshore Wind Farm is a 1.2GW UK project delivering offshore renewable power to about 1 million homes.

✅ 174 turbines over 407 km2; Siemens Gamesa supply chain in the UK

✅ 1.2GW capacity can power ~1m homes; phases scale with 10MW+ turbines

✅ Supports UK grid, replaces delayed nuclear, cuts fossil generation

 

An offshore windfarm on the Yorkshire coast that will dwarf the world’s largest when completed is to supply its first power to the UK electricity grid this week, mirroring advances in tidal electricity projects delivering to the grid as well.

The Danish developer Ørsted, which has installed the first of 174 turbines at Hornsea One, said it was ready to step up its plans and fill the gap left by failed nuclear power schemes.

The size of the project takes the burgeoning offshore wind power sector to a new scale, on a par with conventional fossil fuel-fired power stations.

Hornsea One will cover 407 square kilometres, five times the size of the nearby city of Hull. At 1.2GW of capacity it will power 1m homes, making it about twice as powerful as today’s biggest offshore windfarm once it is completed in the second half of this year.

“The ability to generate clean electricity offshore at this scale is a globally significant milestone at a time when urgent action needs to be taken to tackle climate change,” said Matthew Wright, UK managing director of Ørsted, the world’s biggest offshore windfarm builder.

The power station is only the first of four planned in the area, with a green light and subsidies already awarded to a second stage due for completion in the early 2020s, and interest from Japanese utilities underscoring growing investor appetite.

The first two phases will use 7MW turbines, which are taller than London’s Gherkin building.

But the latter stages of the Hornsea development could use even more powerful, 10MW-plus turbines. Bigger turbines will capture more of the energy from the wind and should lower costs by reducing the number of foundations and amount of cabling firms need to put into the water, with developers noting that offshore wind can compete with gas in the U.S. as costs fall.

Henrik Poulsen, Ørsted’s chief executive, said he was in close dialogue with major manufacturers to use the new generation of turbines, some of which are expected to approach the height of the Shard in London, the tallest building in the EU.

The UK has a great wind resource and shallow enough seabed to exploit it, and could even “power most of Europe if it [the UK] went to the extreme with offshore”, he said.

Offshore windfarms could help ministers fill the low carbon power gap created by Hitachi and Toshiba scrapping nuclear plants, the executive suggested. “If nuclear should play less of a role than expected, I believe offshore wind can step up,” he said.

New nuclear projects in Europe had been “dramatically delayed and over budget”, he added, in comparison to “the strong track record for delivering offshore [wind]”.

The UK and Germany installed 85% of new offshore wind power capacity in the EU last year, according to industry data, with wind leading power across several markets. The average power rating of the turbines is getting bigger too, up 15% in 2018.

The turbines for Hornsea One are built and shipped from Siemens Gamesa’s factory in Hull, part of a web of UK-based suppliers that has sprung up around the growing sector, such as Prysmian UK's land cables supporting grid connections.

Around half of the project’s transition pieces, the yellow part of the structure that connects the foundation to the tower, are made in Teeside. Many of the towers themselves are made by a firm in Campbeltown in the Scottish highlands. Altogether, about half of the components for the project are made in the UK.

Ørsted is not yet ready to bid for a share of a £60m pot of further offshore windfarm subsidies, to be auctioned by the government this summer, but expects the price to reach even more competitive levels than those seen in 2017.

Like other international energy companies, Ørsted has put in place contingency planning in event of a no-deal Brexit – but the hope is that will not come to pass. “We want a Brexit deal that will facilitate an orderly transition out of the union,” said Poulsen.

Huge offshore wind turbine that can power 18,000 homes

Siemens Gamesa SG 14-222 DD advances offshore wind with a 14 MW direct-drive turbine, 108 m blades, a 222 m rotor, optional 15 MW boost, powering about 18,000 homes; prototype 2021, commercial launch 2024.

 

Key Points

A 14 MW offshore wind turbine with 108 m blades and a 222 m rotor, upgradable to 15 MW, targeting commercial use in 2024.

✅ 14 MW direct-drive, upgradable to 15 MW

✅ 108 m blades, 222 m rotor diameter

✅ Powers about 18,000 European homes annually

 

Siemens Gamesa Renewable Energy (SGRE) has released details of a 14-megawatt (MW) offshore wind turbine, as offshore green hydrogen production gains attention, in the latest example of how technology in the sector is increasing in scale.

With 108-meter-long blades and a rotor diameter of 222 meters, the dimensions of the SG 14-222 DD turbine are significant.

In a statement Tuesday, SGRE said that one turbine would be able to power roughly 18,000 average European households annually, while its capacity can also be boosted to 15 MW if needed. A prototype of the turbine is set to be ready by 2021, and it’s expected to be commercially available in 2024, as forecasts suggest a $1 trillion business this decade.

As technology has developed over the last few years, the size of wind turbines has increased, and renewables are set to shatter records globally.

Last December, for example, Dutch utility Eneco started to purchase power produced by the prototype of GE Renewable Energy’s Haliade-X 12 MW wind turbine. That turbine has a capacity of 12 MW, a height of 260 meters and a blade length of 107 meters.

The announcement of Siemens Gamesa’s new turbine plans comes against the backdrop of the coronavirus pandemic, which is impacting renewable energy companies around the world, even as wind power sees growth despite Covid-19 in many markets.

Earlier this month, the European company said Covid-19 had a “direct negative impact” of 56 million euros ($61 million) on its profitability between January and March, amid factory closures in Spain and supply chain disruptions. This, it added, was equivalent to 2.5% of revenues during the quarter.

The pandemic has, in some parts of the world, altered the sources used to power society. At the end of April, for instance, it was announced that a new record had been set for coal-free electricity generation in Great Britain, where UK offshore wind growth has accelerated, with a combination of factors — including coronavirus-related lockdown measures — playing a role.

On Tuesday, the CEO of another major wind turbine manufacturer, Danish firm Vestas, sought to emphasize the importance of renewable energy in the years and months ahead, and the lessons the U.S. can learn from the U.K. on wind deployment.

“I think we have actually, throughout this crisis, also shown to all society that renewables can be trusted,” Henrik Andersen said during an interview on CNBC’s Street Signs.

“But we both know ... that that transformation of energy sources is not going to happen overnight, it’s not going to happen from a quarter to a quarter, it’s going to happen by consistently planning year in, year out.”

Biden calls for 100 percent clean electricity by 2035. Here’s how far we have to go.

Biden Clean Energy Plan 2035 accelerates carbon-free electricity with renewables, nuclear, hydropower, and biomass, invests $2T in EVs, grid and energy efficiency, and tightens fuel economy standards beyond the Clean Power Plan.

 

Key Points

A $2T U.S. climate plan for carbon-free power by 2035, boosting renewables, nuclear, EVs, efficiency, and grid upgrades.

✅ Targets a zero-carbon electric grid nationwide by 2035

✅ Includes renewables, nuclear, hydropower, and biomass in standard

✅ Funds EVs, grid modernization, weatherization, and fuel economy rules

 

This month the Democratic presumptive presidential nominee, Joe Biden, outlined an ambitious plan, including Biden’s solar plan to expand clean energy, for tackling climate change that shows how far the party has shifted on the issue since it controlled the White House.

President Barack Obama’s Clean Power Plan had called for the electricity sector to cut its carbon pollution 32 percent by 2030, and did not lay out a trajectory for phasing out oil, coal or natural gas production.

This year, Democratic 2020 hopefuls such as Sen. Bernie Sanders (I-Vt.) went much further, suggesting the United States should derive all of its electricity from renewable sources by 2030, moving to 100% renewables as part of a $16.3 trillion plan to wean the nation away from fossil fuels. Many other congressional Democrats have embraced the Green New Deal — the nonbinding resolution calling for a carbon-free power sector by 2030 and more energy efficient buildings and vehicles, along with a massive investment in electric vehicles and high-speed rail.

Last year, 38 percent of U.S. electricity generated came from clean sources, according to a Washington Post analysis of data from the U.S. Energy Information Administration, and in April renewables hit a record 28% nationwide.

Biden’s new plan, which carries a price tag of $2 trillion, would eliminate carbon emissions from the electric sector by 2035, impose stricter gas mileage standards, fund investments to weatherize millions of homes and commercial buildings, and upgrade the nation’s transportation system. To reach its 2035 carbon-free electricity goal, the campaign includes wind, solar and several forms of energy, acknowledging why the grid isn’t yet 100% renewable while balancing reliability, that are not always counted in state renewable portfolio standards, such as nuclear, hydropower and biomass.

“A great appeal of the Biden proposal is that it is much closer to targeting carbon directly, which is the ultimate enemy, and plays fewer favorites with particular technologies,” said Michael Greenstone, who directs the University of Chicago’s Energy Policy Institute. “This will reduce the costs to consumers and give more carbon bang for the buck.”

But some environmentalists, such as Friends of the Earth President Erich Pica, question the idea of including more controversial carbon-free technologies. “There is no role for nuclear in a least-cost, low carbon world. Including these dinosaurs in a clean energy standard is going to incentivize industry efforts to keep aging, dangerous facilities online,” Pica said in an email.

Hydropower, which relies on a system of moving water that constantly recharges, is defined as renewable by the Environmental Protection Agency. Biomass is often considered as carbon neutral because even though it releases carbon dioxide when it is burned, the plants capture nearly the same amount of CO2 while growing.


Both forms of energy have come under fire for their environmental impacts, however. Damming streams and rivers can destroy fish habitat and make it more difficult for them to spawn, and it also seems unlikely that hydropower will expand its current 6 percent share of the nation’s electrical grid.

Many experts argue that classifying biomass energy as carbon neutral provides an incentive to cut down trees that would otherwise remain standing and sequester carbon. “If burning this wood were good for the climate, then we should not recycle paper, we should burn it,” noted Tim Searchinger, a research scholar at the Princeton School of Public and International Affairs.

Illinois lead the nation in the amount of electricity generated from nuclear power

More than half of the country — 30 states, Washington, and three territories — have adopted a renewable portfolio standard (RPS), according to the National Conference of State Legislatures, and seven states and one territory have set renewable energy goals. While 14 states, along with the District, Puerto Rico and the Virgin Islands, have established requirements of 50 percent or more carbon-free electricity, nearly as many have set theirs at 15 percent or less.

Maine Gov. Janet Mills (D), who has called for 100% renewable electricity in the state, has pushed clean electricity aggressively since taking office in 2019, lifting a wind energy moratorium imposed by her predecessor and signing bills aimed at expanding the state’s carbon-free energy sources. Biomass accounts for a quarter of the state’s electricity, more than any other state.

New York has one of the country’s most ambitious climate targets, which it scaled up last year. It aims to obtain 70 percent of its power from renewable sources within a decade, a period when renewables surpassed coal in U.S. generation, and eliminate carbon altogether by 2040, even as the state is in the process of shutting down a major nuclear plant near New York City, Indian Point, which is slated to cease operating on April 30, 2021.

... while other states are weakening theirs

Last year, Ohio weakened its renewable energy standard from a target of 12.5 percent in 2027 to 8.5 percent by 2026, even as renewables topped coal nationwide for the first time in over a century, without setting any future goals, and jettisoned its energy efficiency standard. West Virginia — which established modest renewable requirements in 2009 — repealed them altogether in 2015, the year they were set to take effect.

Nova Scotia can't order electric utility to lower power rates, minister says

Nova Scotia Power Rate Regulation explains how the privately owned utility is governed by the Utility Review Board, limiting government authority, while COVID-19 relief measures include suspended disconnections, waived fees, payment plans, and emergency assistance.

 

Key Points

URB oversight where the board, not the province, sets power rates, with COVID-19 relief pausing disconnections and fees.

✅ Province lacks authority to order rate cuts

✅ URB regulates Nova Scotia Power rates

✅ Relief: no disconnections, waived fees, payment plans

 

The province can't ask Nova Scotia Power to lower its rates to ease the financial pressure on out-of-work residents because it lacks the authority to take that kind of action, even as the Nova Scotia regulator approved a 14% hike in a separate proceeding, the provincial energy minister said Thursday.

Derek Mombourquette said he is in "constant contact" with the privately owned utility.

"The conversations are ongoing with Nova Scotia Power," he said after a cabinet meeting.

When asked if the Liberal government would order the utility to lower electricity rates as households and businesses struggle with the financial fallout from the COVID-19 pandemic, Mombourquette said there was nothing he could do.

"We don't have the regulatory authority as a government to reduce the rates," he told reporters during a conference call.

"They're independent, and they are regulated through the (Nova Scotia Utility Review Board). My conversations with Nova Scotia Power essentially have been to do whatever they can to support Nova Scotians, whether it's residents or businesses in this very difficult time."

Asked if the board would take action, the minister said: "I'm not aware of that," despite the premier's appeals to regulators in separate rate cases.

However, the minister noted that the utility, owned by Emera Inc., has suspended disconnections for bill non-payment for at least 90 days, a step similar to reconnection efforts by Hydro One announced in Ontario.

It has also relaxed payment timelines and waived penalties and fees, while some jurisdictions offered lump-sum credits to help with bills.

Nova Scotia Power CEO Wayne O'Connor has also said the company is making additional donations to a fund available to help low-income individuals and families pay their energy bills.

In late March, Ontario cut electricity rates for residential consumers, farms and small businesses in response to a surge in people forced to work from home as a result of the pandemic, alongside bill support measures for ratepayers.

Premier Doug Ford said there would be a 45-day switch to off-peak rates, later moving to a recovery rate framework, which meant electricity consumers would be paying the lowest rate possible at any time of day.

The change was expected to cost the province about $162 million.

Some in Tennessee could be without power for weeks after strong storms hit

Middle Tennessee Power Outages disrupt 100,000+ customers as severe thunderstorms, straight-line winds, downed trees, and debris challenge Nashville crews, slow restoration amid COVID-19, and threaten more hail, flash flooding, and damaging gusts.

 

Key Points

Blackouts across Nashville after severe storms and winds, leaving customers without power and facing restoration delays.

✅ Straight-line winds 60-80 mph toppled trees and power lines

✅ 130,000+ customers impacted; some outages may last 1-2 weeks

✅ Restoration slowed by debris, COVID-19 protocols, and new storms

 

Some middle Tennessee residents could be without electricity for up to two weeks after strong thunderstorms swept through the area Sunday, knocking out power for more than 100,000 customers, a scale comparable to Los Angeles outages after a station fire.

"Straight line winds as high as 60-80 miles per hour knocked down trees, power lines and power polls, interrupting power to 130,000 of our 400,000+ customers," Nashville Electric said in a statement Monday. The utility said the outage was one of the largest on record, though Carolina power outages recently left a quarter-million without power as well.

"Restoration times will depend on individual circumstances. In some cases, power could be out for a week or two" as challenges related to coronavirus and the need for utilities adapt to climate change complicated crews' responses and more storms were expected, the statement said. "This is unfortunate timing on the heels of a tornado and as we deal with battling COVID-19."

Metropolitan Nashville and Davidson County Mayor John Cooper also noted that the power outages were especially inconvenient, a challenge similar to Hong Kong families without power during Typhoon Mangkhut, as people were largely staying home to slow the spread of coronavirus. He also pointed out that the storms came on the two month anniversary of the Nashville tornado that left at least two dozen people dead.

"Crews are working diligently to restore power and clear any debris in neighborhoods," Cooper said.

He said that no fatalities were reported in the county but sent condolences to Spring Hill, whose police department reported that firefighter Mitchell Earwood died during the storm due to "a tragic weather-related incident" while at his home and off duty. He had served with the fire department for 10 years.

The Metro Nashville Department of Public Works said it received reports of more than 80 downed trees in Davidson County.

Officials also warn that copper theft can be deadly when electrical infrastructure is damaged after storms.

The National Weather Service Nashville said a 72 mph wind gust was measured at Nashville International Airport — the fifth fastest on record.

The weather service warned that strong storms with winds of up to 75 mph, large hail, record-long lightning bolt potential seen in the U.S., and isolated flash flooding could hit middle Tennessee again Monday afternoon and night.

"Treat Severe Thunderstorm Warnings the same way you would Tornado Warnings and review storm safety tips before you JUST TAKE SHELTER," the NWS instructs. "70 mph is 70 mph whether it's spinning around in a circle or blowing in a straight line."
