A lightning strike to a north central Wisconsin power plant will carry a hefty price: $34 million.

The tab for Wisconsin Public Service Corp. breaks down to $8.3 million for repairs to the plant and $26 million in higher costs for power the utility must purchase to replace that generated by the plant, near Wausau. The Oct. 6 strike was the second time in two years that the plant was knocked out of service because of a lightning strike.

Wisconsin Public Service Corp., based in Green Bay, said the damage was worse than it first projected. A detailed inspection of the plant revealed damage to the power plant's turbine and generator rotors, said Terry Jensky, vice president of energy supply operations at Wisconsin Public Service.

The plant is expected to be out of service until late 2007 or early 2008, instead of this month.

The plant generates 321 megawatts of electricity, or enough to power more than 160,000 homes. In August 2006, the same power plant was struck by lightning, resulting in appeals by the utility for customers to curtail electricity use in the Wausau, Minocqua and Rhinelander areas.

The utility also cut off power supply to large manufacturing customers. The plant returned to service within a few days, a utility spokeswoman said.

If there's any bright side to the second lightning strike, Jensky said, "at least we were through the summer when peak demand for air-conditioning loads can create an increased electric reliability issue." The damage came despite installation last year of "a state-of-the-art lightning suppression" system that was in operation at the time of the latest strike, the utility says in a letter filed with regulators.

State regulators have authorized the utility to seek to recover the $26 million from its customers at a later date. A request to recover the repair costs of $8.3 million is pending.

In a letter to state regulators, the utility says the lightning strike would reduce profit by 0.5% in 2007 - which would translate to 7 cents a share in lower earnings for the company's parent company, Integrys Energy Group Inc. of Chicago. That financial hit wouldn't reduce earnings if the state Public Service Commission approves the utility's proposal seeking to recover those costs from customers at a later date.

The calls to conserve power last summer after the lightning strike and a fire at the plant provided a stark reminder of the problems experienced by the state's power grid in the past decade. The state experienced widespread electricity shortages in the late 1990s that spawned construction of power plants and high-voltage transmissions lines.

That building boom includes two Wausau-area projects: a $750 million coal-fired power plant that will open next year near the plant struck by lightning, and a controversial 345,000-volt, $420 million power line that will extend from Wausau to Duluth, Minn. Both projects are expected to be generating and distributing power by next summer.

Germany - A needed nuclear option for climate change

Germany Nuclear Debate Amid Energy Crisis highlights nuclear power vs coal and natural gas, renewables and hydropower limits, carbon emissions, energy security, and baseload reliability during Russia-related supply shocks and winter demand.

 

Key Points

Germany Nuclear Debate Amid Energy Crisis weighs reactor extensions vs coal revival to bolster security, curb emissions.

✅ Coal plants restarted; nuclear shutdown stays on schedule.

✅ Energy security prioritized amid Russian gas supply cuts.

✅ Emissions likely rise despite renewables expansion.

 

Peel away the politics and the passion, the doomsaying and the denialism, and climate change largely boils down to this: energy. To avoid the chances of catastrophic climate change while ensuring the world can continue to grow — especially for poor people who live in chronically energy-starved areas — we’ll need to produce ever more energy from sources that emit little or no greenhouse gases.

It’s that simple — and, of course, that complicated.

Zero-carbon sources of renewable energy like wind and solar have seen tremendous increases in capacity and equally impressive decreases in price in recent years, while the decades-old technology of hydropower is still what the International Energy Agency calls the “forgotten giant of low-carbon electricity.”

And then there’s nuclear power. Viewed strictly through the lens of climate change, nuclear power can claim to be a green dream, even as Europe is losing nuclear power just when it really needs energy most.

Unlike coal or natural gas, nuclear plants do not produce direct carbon dioxide emissions when they generate electricity, and over the past 50 years they’ve reduced CO2 emissions by nearly 60 gigatonnes. Unlike solar or wind, nuclear plants aren’t intermittent, and they require significantly less land area per megawatt produced. Unlike hydropower — which has reached its natural limits in many developed countries, including the US — nuclear plants don’t require environmentally intensive dams.

As accidents at Chernobyl and Fukushima have shown, when nuclear power goes wrong, it can go really wrong. But newer plant designs reduce the risk of such catastrophes, which themselves tend to garner far more attention than the steady stream of deaths from climate change and air pollution linked to the normal operation of conventional power plants.

So you might imagine that those who see climate change as an unparalleled existential threat would cheer the development of new nuclear plants and support the extension of nuclear power already in service.

In practice, however, that’s often not the case, as recent events in Germany underline.

When is a Green not green?
The Russian war in Ukraine has made a mess of global energy markets, but perhaps no country has proven more vulnerable than Germany, reigniting debate over a possible resurgence of nuclear energy in Germany among policymakers.

At the start of the year, Russian exports supplied more than half of Germany’s natural gas, along with significant portions of its oil and coal imports. Since the war began, Russia has severely curtailed the flow of gas to Germany, putting the country in a state of acute energy crisis, with fears growing as next winter looms.

With little natural gas supplies of the country’s own, and its heavily supported renewable sector unable to fully make up the shortfall, German leaders faced a dilemma. To maintain enough gas reserves to get the country through the winter, they could try to put off the closure of Germany’s last three remaining nuclear reactors temporarily, which were scheduled to shutter by the end of 2022 as part of Germany’s post-Fukushima turn against nuclear power, and even restart already closed reactors.

Or they could try to reactivate mothballed coal-fired power plants, and make up some of the electricity deficit with Germany’s still-ample coal reserves.

Based on carbon emissions alone, you’d presumably go for the nuclear option. Coal is by far the dirtiest of fossil fuels, responsible for a fifth of all global greenhouse gas emissions — more than any other single source — as well as a soup of conventional air pollutants. Nuclear power produces none of these.

German legislators saw it differently. Last week, the country’s parliament, with the backing of members of the Green Party in the coalition government, passed emergency legislation to reopen coal-powered plants, as well as further measures to boost the production of renewable energy. There would be no effort to restart closed nuclear power plants, or even consider a U-turn on the nuclear phaseout for the last active reactors.

“The gas storage tanks must be full by winter,” Robert Habeck, Germany’s economy minister and a member of the Green Party, said in June, echoing arguments that nuclear would do little to solve the gas issue for the coming winter.

Partially as a result of that prioritization, Germany — which has already seen carbon emissions rise over the past two years, missing its ambitious emissions targets — will emit even more carbon in 2022.

To be fair, restarting closed nuclear power plants is a far more complex undertaking than lighting up old coal plants. Plant operators had only bought enough uranium to make it to the end of 2022, so nuclear fuel supplies are set to run out regardless.

But that’s also the point. Germany, which views itself as a global leader on climate, is grasping at the most carbon-intensive fuel source in part because it made the decision in 2011 to fully turn its back on nuclear for good at the time, enshrining what had been a planned phase-out into law.

BC Hydro Expects To See Electricity Usage Rise This Holiday Season

BC Hydro Holiday Electricity Usage is set to rise as energy demand increases during peak 4-10 pm on Christmas and Boxing Day, driven by larger gatherings, more cooking, and eased COVID-19 restrictions province-wide.

 

Key Points

Expected rise in power demand on Christmas and Boxing Day evenings versus 2020, driven by larger gatherings and cooking.

✅ Peak hours 4-10 pm expected to rise in provincial load.

✅ 2020 saw 4% and 7% drops vs 2019 on Christmas and Boxing Day.

✅ Holiday lighting adds ~3% to use; switching to LED can save ~$40.

 

BC Hydro data showed residential electricity load in the Cariboo and throughout the province, even as drought affects generation dynamics heading into winter, dropped on Christmas Day and Boxing Day in 2020.

Northern Community Relations Manager, Bob Gammer, said the decrease was due in part to more people following the COVID-19 restrictions and not getting together for big meals, even though 2018 Earth Hour usage increased elsewhere illustrates how behavior can sometimes raise demand.

However, this year Gammer said between 4 and 10 pm on those two days, BC Hydro does expect to see a change in overall usage, aligning with all-time high demand trends reported recently in B.C.

“On Christmas Day and Boxing Day, we expect to see increases through those hours and a little bit more so between 4 and 10 pm we should see the amount of power being consumed across the province, as record-breaking 2021 demand indicated earlier, going up compared to what it was on those two days last year.”

In 2020 on Christmas Day evening hydro usage dropped by over 4 percent and Boxing Day evening decreased by 7 percent compared to 2019, whereas regions like Calgary's winter demand have seen spikes during extreme cold.

Gammer added after BC Hydro surveyed their customers and introduced a winter payment plan, they expect to see a lot more cooking happening on Christmas Day and Boxing Day this year as people are intending to have larger gatherings and visit friends.

We asked Gammer about hydro usage when it comes to homes decked out for the holidays, and how that compares to newer loads like crypto mining activity in B.C.

“The Christmas lighting displays people have, not just indoors but outdoors as well, what we’re seeing is about a 3 percent increase in electricity consumption overall through the Christmas season. If people switch, if you still have older lights that are incandescent, switch those over to LED, and through the season it could wind up saving you $40 in electricity just switching over about 8 strings of lights to LED.”

Customers on the hook for $5.5 billion in deferred BC Hydro operating costs: report

BC Hydro Deferred Regulatory Assets detail $5.5 billion in costs under rate-regulated accounting, to be recovered from ratepayers, highlighting B.C. Utilities Commission oversight, audit scrutiny, financial reporting impacts, and public utility governance.

 

Key Points

BC Hydro defers costs as regulatory assets to recover from ratepayers, influencing rates and financial reporting.

✅ $5.5B in deferred costs recorded as net regulatory assets

✅ Rate impacts tied to B.C. Utilities Commission oversight

✅ Auditor General to assess accounting and governance

 

Auditor General Carol Bellringer says BC Hydro has deferred $5.5 billion in expenses that it plans to recover from ratepayers in the future, as rates to rise by 3.75% over two years.

Bellringer focuses on the deferred expenses in a report on the public utility's use of rate-regulated accounting to control electricity rates for customers.

"As of March 31, 2018, BC Hydro reported a total net regulatory asset of $5.455 billion, which is what ratepayers owe," says the report. "BC Hydro expects to recover this from ratepayers in the future. For BC Hydro, this is an asset. For ratepayers, this is a debt."

She says rate-regulated accounting is used widely across North America, but cautions that Hydro has largely overridden the role of the independent B.C. Utilities Commission to regulate rates.

"We think it's important for the people of B.C. and our members of the legislative assembly to better understand rate-regulated accounting in order to appreciate the impact it has on the bottom line for BC Hydro, for government as a whole, for ratepayers and for taxpayers, especially following a three per cent rate increase in April 2018," Bellringer said in a conference call with reporters.

Last June, the B.C. government launched a two-phase review of BC Hydro to find cost savings and look at the direction of the Crown utility, amid calls for change from advocates.

The review came shortly after a planned government rate freeze was overturned by the utilities commission, which resulted in a three per cent rate increase in April 2018.

A statement by BC Hydro and the government says a key objective of the review due this month is to enhance the regulatory oversight of the commission.

Bellringer's office will become BC Hydro's auditor next year — and will be assessing the impact of regulation on the utility's financial reporting.

"It is a complex area and confidence in the regulatory system is critical to protect the public interest," wrote Bellringer.

Biden administration pushes to revitalize coal communities with clean energy projects

Coal-to-Clean Energy Hubs leverage Bipartisan Infrastructure Law and Inflation Reduction Act funding to repurpose mine lands with microgrids, advanced nuclear, carbon capture, and rare earth processing, boosting energy security, jobs, and grid modernization.

 

Key Points

They are federal projects converting coal communities and mine lands into clean energy hubs, repurposing infrastructure.

✅ DOE demos on mine lands: microgrids, nuclear, carbon capture.

✅ Funding from BIL, CHIPS and IRA targets energy communities.

✅ Rare earths from coal waste bolster EV supply chains.

 

The Biden administration is channeling hundreds of millions of dollars in clean energy funding from recent legislation into its efforts to turn coal communities into clean energy hubs, the White House said.

The administration gave an update on its push across agencies to kick-start projects nationwide with funding Congress approved during Biden’s first two years in office. The effort includes $450 million from the Bipartisan Infrastructure Law that the Department of Energy will allocate to an array of new clean energy demonstration projects on former mine lands.

“These projects could focus on a range of technologies from microgrids to advanced nuclear to power plans with carbon capture,” Energy Secretary Jennifer Granholm said on a call with reporters Monday. “They’ll prove out the potential to reactivate or repurpose existing infrastructure like transmission lines and substations across an aging U.S. power grid, and these projects could spur new economic development in these communities.”

Among the projects the White House highlighted, it said $16 million from the infrastructure law will go to the University of North Dakota and West Virginia University to create design studies for the first-ever full-scale refinery facility in the U.S. that could extract and separate rare earth elements and minerals from coal mine waste streams. The materials are critical for electric vehicle-battery components that are currently heavily sourced from outside the U.S.

“Those efforts will pave the way toward building a first of its kind facility that produces essential materials for solar panels, wind turbines, EVs and more while cleaning up polluted land and water and creating good-paying jobs for local workers,” Granholm said.

Biden created an interagency working group focused on revitalizing coal-power communities through federal investments when he took office. In 2021, the group selected 25 priority areas ranging from West Virginia to Wyoming to focus on development, as high natural gas prices strengthened the case for clean electricity. There are nearly 18,000 identified mine sites across 1.5 million acres in the United States, according to the White House.

The massive effort fits into a broader Biden administration push to both fight climate change and support communities that have lost economic activity during a transition away from fossil fuel sources such as coal. While Biden’s most ambitious clean energy plans fell flat in Congress in the face of opposition from Republicans and some Democrats after the previous administration’s power plant overhaul, three major laws still unlocked funding for his administration to deploy.

Many of the initiatives are made possible through the Bipartisan Infrastructure Law, Chips and Science Act and the Inflation Reduction Act, even without a clean electricity standard on the books. The task force aims to make sure communities most affected by the changing energy landscape are taking maximum advantage of the federal benefits.

“Those new and expanded operations are coming to energy communities and creating good paying jobs,” Biden’s senior advisor for clean energy innovation and implementation John Podesta said on the call. “These laws can provide substantial federal support to energy communities like capping abandoned oil and gas wells, extracting critical minerals, building battery factories and launching demonstration projects in carbon capture or green hydrogen.”

The administration touted the potential benefits of the Inflation Reduction Act, a bill passed by Democrats to spur clean energy investments last year, even as early assessments show mixed results to date. At the time, U.S. consumers were dealing with decades-high inflation fueled in part by an energy crisis and high gas prices that drove debate — a point Republicans emphasized as the plan moved through Congress.

Deputy Treasury Secretary Wally Adeyemo said the Inflation Reduction Act aims to both “lower the deficit, as well as promote our energy security, lowering energy costs for consumers and combatting climate change.”

“As the Treasury works to implement the law, we’re focused on ensuring that all Americans benefit from the growth of the clean energy economy, particularly those who live in communities that have been dependent on the energy sector for job for a long time,” Adeyemo told reporters. “Economic growth and productivity are higher when all communities are able to reach their full potential.”

Enel Starts Operations of 450 MW Wind Farm in U.S

High Lonesome Wind Farm powers Texas with 500 MW of renewable energy, backed by a 12-year PPA with Danone North America and a Proxy Revenue Swap, cutting CO2 emissions as Enel's largest project to date.

 

Key Points

A 500 MW Enel wind project in Texas, supplying renewable power via PPAs and hedged by a Proxy Revenue Swap.

✅ 450 MW online; expanding to 500 MW in early 2020

✅ 12-year PPA with Danone North America for 20.6 MW

✅ PRS hedge with Allianz and Nephila stabilizes revenues

 

Enel, through its US renewable subsidiary Enel Green Power North America, Inc. (“EGPNA”), has started operations of its 450 MW High Lonesome wind farm in Upton and Crockett Counties, in Texas, the largest operational wind project in the Group’s global renewable portfolio, alongside a recent 90 MW Spanish wind build in its European pipeline. Enel also signed a 12-year, renewable energy power purchase agreement (PPA) with food and beverage company Danone North America, a Public Benefit Corporation, for physical delivery of the renewable electricity associated with 20.6 MW, leading to an additional 50 MW expansion of High Lonesome that will increase the plant’s total capacity to 500 MW. The construction of the 50 MW expansion is currently underway and operations are due to start in the first quarter of 2020.

“The start of operations of Enel’s largest wind farm in the world marks a significant achievement for our company and reinforces our global commitment to accelerated renewable energy growth,” said Antonio Cammisecra, CEO of Enel Green Power, referencing the largest wind project constructed in North America as evidence of market momentum. “This milestone is matched with a new partnership with Danone North America to support their renewable goals, a reinforcement of our continued commitment to provide customers with tailored solutions to meet their sustainability goals.”

The agreement between Enel and Danone North America will provide enough electricity to produce the equivalent of almost 800 million cups of yogurt1 and over 80 million gallons2 of milk each year and support the food and beverage company’s commitment to securing 100% of its purchased electricity from renewable sources by 2030, in a market where North Carolina’s first wind farm is now fully operational and expanding access to clean power.

Mariano Lozano, president and CEO of Danone North America, added:“This is an exciting and significant step as we continue to advance our 2030 renewable electricity goals. As a public benefit corporation committed to balancing the needs of our business with those of society and the planet, we truly believe that this agreement makes sense from both a business and sustainability point of view. We’re delighted to be working with Enel Green Power to expand their High Lonesome wind farm and grow the renewable electricity infrastructure, such as New York’s biggest offshore wind projects, here in the US.”

In addition, as more US wind projects come online, such as TransAlta’s 119 MW project, the energy produced by a 295 MW portion of the project will be hedged under a Proxy Revenue Swap (PRS) with insurer Allianz Global Corporate & Specialty, Inc.'s Alternative Risk Transfer unit (Allianz), and Nephila Climate, a provider of weather and climate risk management products. The PRS is a financial derivative agreement designed to produce stable revenues for the project regardless of power price fluctuations and weather-driven intermittency, hedging the project from this kind of risk in addition to that associated with price and volume.

Under the PRS agreement, and as other projects begin operations, like Building Energy’s latest plant, High Lonesome will receive fixed payments based on the expected value of future energy production, with adjustments paid depending on how the realized proxy revenue of the project differs from the fixed payment. The PRS for High Lonesome, which is the largest by capacity for a single plant globally and the first agreement of its kind for Enel, was executed in collaboration with REsurety, Inc.

The investment in the construction of the 500 MW plant amounts to around 720 million US dollars. The wind farm is due to generate around 1.9 TWh annually, comparable to a 280 MW Alberta wind farm’s output, while avoiding the emission of more than 1.2 million tons of CO2 per year.

N.S. approves new attempt to harness Bay of Fundy's powerful tides

Bay of Fundy Tidal Energy advances as Nova Scotia permits Jupiter Hydro to test floating barge platforms with helical turbines in Minas Passage, supporting renewable power, grid-ready pilots, and green jobs in rural communities.

 

Key Points

A Nova Scotia tidal energy project using helical turbines to generate clean power and create local jobs.

✅ Permits enable 1-2 MW prototypes near Minas Passage

✅ Floating barge platforms with patented helical turbines

✅ PPA at $0.50/kWh with Nova Scotia Power

 

An Alberta-based company has been granted permission to try to harness electricity from the powerful tides of the Bay of Fundy.

Nova Scotia has issued two renewable energy permits to Jupiter Hydro.

Backers have long touted the massive energy potential of Fundy's tides -- they are among the world's most powerful -- but large-scale commercial efforts to harness them have borne little fruit so far, even as a Scottish tidal project recently generated enough power to supply nearly 4,000 homes elsewhere.

The Jupiter application says it will use three "floating barge type platforms" carrying its patented technology. The company says it uses helical turbines mounted as if they were outboard motors.

"Having another company test their technology in the Bay of Fundy shows that this early-stage industry continues to grow and create green jobs in our rural communities," Energy and Mines Minister Derek Mombourquette said in a statement.

The first permit allows the company to test a one-megawatt prototype that is not connected to the electricity grid.

The second -- a five-year permit for up to two megawatts -- is renewable if the company meets performance standards, environmental requirements and community engagement conditions.

Mombourquette also authorized a power purchase agreement that allows the company to sell the electricity it generates to the Nova Scotia grid through Nova Scotia Power for 50 cents per kilowatt hour.

On its web site, Jupiter says it believes its approach "will prove to be the most cost effective marine energy conversion technology in the world," even as other regional utilities consider initiatives like NB Power's Belledune concept for turning seawater into electricity.

The one megawatt unit would have screws which are about 5.5 metres in diameter.

The project is required to obtain all other necessary approvals, permits and authorizations.

It will be located near the Fundy Ocean Research Center for Energy in the Minas Passage and will use existing electricity grid connections.

A study commissioned by the Offshore Energy Research Association of Nova Scotia says by 2040, the tidal energy industry could contribute up to $1.7 billion to Nova Scotia's gross domestic product and create up to 22,000 full-time jobs, a transition that some argue should be planned by an independent body to ensure reliability.

Last month, Nova Scotia Power said it now generates 30 per cent of its power from renewables, as the province moves to increase wind and solar projects after abandoning the Atlantic Loop.

The utility says 18 per cent came from wind turbines, nine per cent from hydroelectric and tidal turbines and three per cent by burning biomass across its fleet.

However, over half of the province's electrical generation still comes from the burning of coal or petroleum coke, even as environmental advocates push to reduce biomass use in the mix. Another 13 per cent come from burning natural gas and five per cent from imports.
