At a cost of $30 million, an electrical generator proposed for Marshfield's Yellowstone Industrial Park looks like a reasonably priced insurance policy.

Do the math.

A megawatt is 1,000 kilowatts, the standard of measure for the sale of electricity to consumers. The plant will produce 55,000 kilowatts for an estimated 500 hours a year - or 27.5 million kilowatt hours annually.

If the debt on the plant was retired over 30 years, it'd cost 3.6 cents a kilowatt hour to pay for construction costs. That's a competitive rate in anyone's book, less than half the Wisconsin average.

Add in the fuel and people to run the facility.

Marshfield Utilities generator would be a peaking unit, meaning it'd be switched on only when electricity demand surpassed the capacity of big generators that run 24/7.

Because it'd burn natural gas, with diesel fuel as a backup, Marshfield Utilities' peaking plant would be expensive to operate, with a fuel cost per kilowatt hour higher than a base load plant.

Taking that into account, the premium on Marshfield Utilities' electrical generating plant gets more costly.

There's a fairly complicated financing mechanism, though, that includes selling bonds to raise the $30 million and then paying them back with credits the utility gets because it has the ability to add electricity to the power grid when it's needed.

But is this like a free lunch?

Not if you consider the nitrogen and sulfur dioxide emissions or the depletion of the earth's fossil fuels. No fuel-burning power plants are entirely green, meaning that they don't have any negative effects on the environment, and Marshfield Utilities' plant wouldn't be an exception.

Natural gas is cleaner burning than coal, the fuel that fires the boilers at Wisconsin Public Service Corp.'s big generators south of Wausau, which are the largest in our region. It's not pollution-free, however.

Power plants make noise. There's a din - a constant, annoying noise - coming from the Wausau-area power plants. In the winter it's not too bad unless you live close. In the summer, it's annoying to nearby residential neighborhoods.

That's why Marshfield Utilities' generator would be built in an industrial park. And if it runs only 500 hours a year and then during peak consumption, it'll be switched off all but about 21 days a year, and even when it runs it'll be mostly during daytime, when usage spikes.

Still, Marshfield is on a path toward declaring itself a sustainable community. If it does, it'll look for ways to reduce its reliance on products and technology that harm the environment. There was a Renewable Energy 101 workshop in January at the University of Wisconsin-Marshfield/Wood County. The Groundwater Guardians seek to protect water resources.

The construction of a fossil fuel power plant flies in the face of those initiatives.

But then again, if Marshfield doesn't have a reliable source of electricity, what good are all those compact fluorescent lights anyway? And a peaking unit is all about strengthening the power grid's reliability.

When the environmental impact statement is done, there'll be more to consider than the cost per kilowatt hour or who will pay off the utility revenue bonds. The Public Service Commission is required to weigh it all before approving or denying permits to build the plant.

As citizens, it's our responsibility to hold the commission and Marshfield Utilities accountable, because there's more riding on this ruling than whether the electricity that runs your refrigerator comes from Kewaunee or is made in Marshfield.

Tesla CEO Elon Musk slams Texas energy agency as unreliable: "not earning that R"

ERCOT Texas Power Grid Crisis disrupts millions amid a winter storm, with rolling blackouts, power outages, and energy demand; Elon Musk criticizes ERCOT as Tesla owners use Camp Mode while wind turbines face icing

 

Key Points

A Texas blackout during a winter storm, exposing ERCOT failures, rolling blackouts, and urgent grid resilience measures.

✅ Millions without power amid record cold and energy demand

✅ Elon Musk criticizes ERCOT over grid reliability failures

✅ Tesla Camp Mode aids warmth during extended outages

 

Tesla CEO Elon Musk on Wednesday slammed the Texas agency responsible for a statewide blackout amid a U.S. grid with frequent outages that has left millions of people to fend for themselves in a freezing cold winter storm.

Musk tweeted that Texas’ power grid manager, the Electricity Reliability Council of Texas (ERCOT), is not earning the “R” in the acronym, highlighting broader grid vulnerabilities that critics have noted.

Musk moved to Texas from California in December and is building a new Tesla factory in Austin. His critique of the state’s electrical grid operator came after multiple Tesla owners in the state said they had slept in their vehicles to keep warm amid the lingering power outage.

In 2019, Tesla released a vehicle with a “Camp Mode,” which enables owners to use the vehicle’s features – like lights and climate control – without significantly depleting the battery.

“We had the power go out for 6 hours last night. Our house does not have gas, and we ran out of firewood... what are we going to do,” one Reddit user wrote on “r/TeslaMotors.”

“So my wife my dog and my newborn daughter slept in the garage in our Model3 all nice and cozy. If I didn't have this car, it would have been a very rough night.”

More than two dozen people have died in the extreme weather this week, some while struggling to find warmth inside their homes. In the Houston area, one family succumbed to carbon monoxide from car exhaust in their garage. Another perished as they used a fireplace to keep warm.

Utilities from Minnesota to Texas and Mississippi have implemented rolling blackouts to ease the burden on power grids straining to meet extreme demand for heat and electricity, as longer, more frequent outages hit systems nationwide.

More than 3 million customers remained without power in Texas, Louisiana and Mississippi, more than 200,000 more in four Appalachian states, and nearly that many in the Pacific Northwest, according to poweroutage.us, which tracks utility outage reports, and advocates warn that millions could face summer shut-offs without protections.

ERCOT said early Wednesday that electricity had been restored to 600,000 homes and businesses by Tuesday night, though nearly 3 million homes and businesses remained without power, as California turns to batteries to help balance demand. Officials did not know when power would be restored.

ERCOT President Bill Magness said he hoped many customers would see at least partial service restored soon but could not say definitively when that would be.

Magness has defended ERCOT’s decision, saying it prevented an “even more catastrophic than the terrible events we've seen this week."

Utility crews raced Wednesday to restore power to nearly 3.4 million customers around the U.S. who were still without electricity in the aftermath of a deadly winter storm, even as officials urge residents to prepare for summer blackouts that could tax systems further, and another blast of ice and snow threatened to sow more chaos.

The latest storm front was expected to bring more hardship to states that are unaccustomed to such frigid weather — parts of Texas, Arkansas and the Lower Mississippi Valley — before moving into the Northeast on Thursday.

"There's really no letup to some of the misery people are feeling across that area," said Bob Oravec, lead forecaster with the National Weather Service, referring to Texas.

Sweden, known for its brutally cold climate, has offered some advice to Texans unaccustomed to such freezing temperatures, as Canadian grids are increasingly exposed to harsh weather that strains reliability. Stefan Skarp of the Swedish power company told Bloomberg on Tuesday: “The problem with sub-zero temperatures and humid air is that ice will form on the wind turbines.”

“When ice freezes on to the wings, the aerodynamic changes for the worse so that wings catch less and less wind until they don't catch any wind at all,” he said.

Why rolling back European electricity prices is tougher than appears

EU Energy Price Crisis drives soaring electricity bills as natural gas sets pay-as-clear power prices; leaders debate price caps, common gas purchasing, market reform, renewables, and ETS changes amid Ukraine war supply shocks.

 

Key Points

A surge in gas-driven power costs linked to pay-as-clear pricing, supply shocks, and policy rifts across the EU market.

✅ Gas sets marginal power price via pay-as-clear mechanism

✅ Spain pushes decoupling and temporary price caps

✅ EU weighs joint gas buying, efficiency, more renewables

 

Nothing grabs politicians' attention faster than angry voters, and they've had plenty to be furious about as natural gas and electricity bills have soared to stomach-churning levels in recent months, as this UK natural gas analysis illustrates across markets.

That's led to a scramble to figure out ways to get those costs down, with emergency price-limiting measures under discussion — but that's turning out to be very difficult, so the likeliest result is that EU leaders meeting later this week won't come up with any solutions.

“There is no single easy answer to tackle the high electricity prices given the diversity of situations among Member States. Some options are only suitable for specific national contexts,” the European Commission said on Wednesday. “They all carry costs and drawbacks.” 

The initial problem was a surge in gas demand in Asia last year coupled with lower-than-normal Russian gas deliveries that left European gas storage at unusually low levels. Now the war in Ukraine is making matters even worse, as pressure grows for the bloc to rapidly cut its imports of Russian oil, coal and natural gas — although some national leaders reject the economic costs that would entail.

"We will end this dependence as quickly as we can, but to do that from one day to the next would mean plunging our country and all of Europe into a recession," German Chancellor Olaf Scholz warned on Wednesday.

The problem for the bloc is that its liberalized electricity market is tightly tied to the price of natural gas; power prices are set by the final input needed to balance demand — called pay-as-clear — which in most cases is set by natural gas. That's led to countries with large amounts of cheaper renewable or nuclear energy seeing sharp spikes in power prices thanks to the cost of that final bit of gas-fired electricity.

A Spanish-led coalition that includes Portugal, Belgium and Italy wants deep reforms to the EU price model, fueling a broader electricity market revamp debate in Brussels.

Others, such as the Netherlands and Germany, strongly oppose such an approach, echoing how nine countries oppose reforms at the EU level, and want to focus on cushioning the effects of the high prices on consumers and businesses, while letting the market operate. 

A third group, largely in Central Europe, wants to use the price spike to revamp or scrap the bloc's Emissions Trading System and to rethink its Fit for 55 climate legislation.

The European Commission has been holding the middle ground — arguing that the current market model makes sense, but encouraging countries to boost the amount of renewable electricity, in a wake-up call to ditch fossil fuels for Europe, to cut energy use and increase efficiency.

In draft conclusions of this week's European Council summit, seen by POLITICO, EU leaders, amid a France-Germany tussle over reform, call for things like a common approach to buying gas, aimed at preventing countries from competing against each other. But there's no big movement on electricity prices.

“It does not seem realistic to expect a result on the energy discussion at this European Council,” one diplomat said, stressing that the governments will need to see more analysis before committing to any more steps.

Looking for action
Spain wanted a much more robust response. Madrid has been arguing since last summer for “decoupling” gas from the electricity market; together with Portugal, it also mulled limiting the wholesale price of electricity to €180 per megawatt-hour — a proposal that Spain abandoned under fire from industry and consumer groups. 

Now Madrid is pushing to get a specific permission in the summit's final conclusions that would allow countries to voluntarily apply certain short-term solutions such as gas price cap strategies, according to a draft with track changes seen by POLITICO.

The issue with a cap is if gas prices are higher than the cap, Spain might not be able to buy any gas.

Independent power project announced by B.C. Hydro now in limbo

Siwash Creek Hydroelectric Project faces downsizing under a BC Hydro power purchase agreement, with run-of-river generation, high grid interconnection costs, First Nations partnership, and surplus electricity from Site C reshaping clean energy procurement.

 

Key Points

A downsized run-of-river plant in BC, co-owned by Kanaka Bar and Green Valley, selling power via a BC Hydro PPA.

✅ Approved at 500 kW under a BC Hydro clean-energy program

✅ Grid interconnection initially quoted at $2.1M

✅ Joint venture: Kanaka Bar and Green Valley Power

 

A small run-of-river hydroelectric project recently selected by B.C. Hydro for a power purchase agreement may no longer be financially viable.

The Siwash Creek project was originally conceived as a two-megawatt power plant by the original proponent Chad Peterson, who holds a 50-per-cent stake through Green Valley Power, with the Kanaka Bar Indian Band holding the other half.

The partners were asked by B.C. Hydro to trim the capacity back to one megawatt, but by the time the Crown corporation announced its approval, it agreed to only half that — 500 kilowatts — under its Standing Order clean-energy program.

“Hydro wanted to charge us $2.1 million to connect to the grid, but then they said they could reduce it if we took a little trim on the project,” said Kanaka Bar Chief Patrick Michell.

The revenue stream for the band and Green Valley Power has been halved to about $250,000 a year. The original cost of running the $3.7-million plant, including financing, was projected to be $273,000 a year, according to the Kanaka Bar economic development plan.

“By our initial forecast, we will have to subsidize the loan for 20 years,” said Michell. “It doesn’t make any sense.”

The Kanaka Band has already invested $450,000 in feasibility, hydrology and engineering studies, with a similar investment from Green Valley.

B.C. Hydro announced it would pursue five purchase agreements last March with five First Nations projects — including Siwash Creek — including hydro, solar and wind energy projects, as two new generating stations were being commissioned at the time. A purchase agreement allows proponents to sell electricity to B.C. Hydro at a set price.

However, at least ten other “shovel-ready” clean energy projects may be doomed while B.C. Hydro completes a review of its own operations and its place in the energy sector, where legal outcomes like the Squamish power project ruling add uncertainty, including B.C.’s future power needs.

With the 1,100-megawatt Site C Dam planned for completion in 2024, and LNG demand cited to justify it, B.C. Hydro now projects it will have a surplus of electricity until the early 2030s.

Even if British Columbians put 300,000 electric vehicles on the road over the next 12 years, amid BC Hydro’s first call for power, they will require only 300 megawatts of new capacity, the company said.

A long-term surplus could effectively halt all small-scale clean energy development, according to Clean Energy B.C., even as Hydro One’s U.S. coal plant remains online in the region.

“(B.C. Hydro) dropped their offer down to 500 kilowatts right around the time they announced their review,” said Michell. “So we filled out the paperwork at 500 kilowatts and (B.C. Hydro) got to make its announcement of five projects.”

In the new few weeks, Kanaka and Green Valley will discuss whether they can move forward with a new financial model or shelve the project, he said.

B.C. Hydro declined to comment on the rationale for downsizing Siwash Creek’s power purchase agreement.

The Kanaka Bar Band successfully operates a 49.9-megawatt run-of-river plant on Kwoiek Creek with partners Innergex Renewable Energy.

Rio Tinto seeking solutions that transform heat from underground mines into electricity

Rio Tinto waste heat-to-electricity initiative captures underground mining thermal energy at Resolution Copper, Arizona, converting it to renewable power for cooling systems and microgrids, advancing decarbonization, energy efficiency, and the miner's 2050 carbon-neutral goal.

 

Key Points

A program converting underground thermal energy into on-site electricity to cut emissions and support mine cooling.

✅ Captures low-grade heat from rock and geothermal water.

✅ Generates electricity for ventilation, refrigeration, microgrids.

✅ Scalable, safe, and grid- or storage-ready for peak demand.

 

The world’s second-largest miner, Rio Tinto announced that it is accepting proposals for solutions that transform waste heat into electricity for reuse from its underground operations.

In a press release, the company said this initiative is aimed at drastically reducing greenhouse gas emissions, even as energy-intensive projects like bitcoin mining operations expand, so that it can achieve its goal of becoming carbon neutral by 2050.

Initially, the project would be implemented at the Resolution copper mine in Arizona, which Rio owns together with BHP (ASX, LON: BHP). At this site, massive electrically-driven refrigeration and ventilation systems, aligned with broader electrified mining practices, are in charge of cooling the work environment because of the latent heat from the underground rock and groundwater. 

THE INITIATIVE IS AIMED AT REDUCING GREENHOUSE GAS EMISSIONS SO THAT RIO CAN ACHIEVE ITS GOAL OF BECOMING CARBON NEUTRAL BY 2050

“When operating, the Resolution copper mine will be a deep underground block cave mine some 7,000 feet (~2 kilometres) deep, with ambient air temperatures ranging between 168°F to 180°F (76°C to 82°C), conditions that, during heat waves, when bitcoin mining power demand can strain local grids, further heighten cooling needs, and underground water at approximately 194°F (90°C),” the media brief states.

“Rio Tinto is seeking solutions to capture and reuse the heat from underground, contributing towards powering the equipment needed to cool the operations. The solution to capture and convert this thermal energy into electrical energy, such as emerging thin-film thermoelectrics, should be safe, environmentally friendly and cost-effective.”

The miner also said that, besides capturing heat for reuse, the solution should generate electrical energy from low range temperatures below the virgin rock temperature and/or from the high thermal water coming from the underground rock, similar to using transformer waste heat for heating in the power sector. 

At the same time, the solution should be scalable and easily transported through the many miles of underground tunnels that will be built to ventilate, extract and move copper ore to the surface.

Rio requires proposals to offer the possibility of distributing the electrical energy generated back into the electrical grid from the mining operation or stored and used at a later stage when energy is required during peak use periods, especially as jurisdictions aim to use more electricity for heat in colder seasons.

Kyiv warns of 'difficult' winter after deadly strikes

Ukraine Winter Energy Attacks strain the power grid as Russian missile strikes hit critical infrastructure, causing blackouts, civilian casualties, and damage in Kyiv, Kherson, and Kharkiv, underscoring air defense needs and looming cold-weather risks.

 

Key Points

Russian strikes on energy infrastructure cause outages, damage, and harm as Ukraine braces for freezing winter months.

✅ Russian missile barrage targets critical infrastructure nationwide.

✅ Power cuts reported in 400 localities; grid stability at risk.

✅ Kyiv seeks more air defenses as winter threats intensify.

 

Ukraine has warned that a difficult winter looms ahead after a massive Russian missile barrage targeted civilian infrastructure, killing three in the south and wounding many across the country.

Russia launched the strikes as Ukraine prepares for a third winter during Moscow's 19-month long invasion and as President Volodymyr Zelensky made his second wartime trip to Washington amid a U.S. end to grid support announcement.

"Most of the missiles were shot down. But only the majority. Not all," Zelensky said, calling for the West to provide Kyiv with more anti-missile systems to help keep the lights on this winter amid ongoing attacks.

The fresh attack came as Poland said it would honour pre-existing commitments of weapons supplies to Kyiv, a day after saying it would no longer arm its neighbour in a mounting row between the two allies.

Moscow hit cities from Rivne in western Ukraine to Kherson in the south, the capital Kyiv and cities in the centre and northeast of the country.

Kyiv also reported power cuts across the country -- in almost 400 cities, towns and villages -- as Russia targeted power plants across the grid, but said it was "too early" to tell if this was the start of a new Russian campaign against its energy sites.

Officials added that electricity reserves could limit scheduled outages if no new large-scale strikes occur.

Last winter many Ukrainians had to go without electricity and heating in freezing temperatures as Russia hit Kyiv's energy facilities.

"Difficult months are ahead: Russia will attack energy and critically important facilities," said Oleksiy Kuleba, the deputy head of Kyiv's presidential office.

Ukraine also said that it had struck a military airfield in Moscow-annexed Crimea, a claim denied by Russian-installed authorities.

'Ceilings fell down'
Russia's overnight strikes were deadliest in the southern Kherson, where three people were killed.

In Kyiv's eastern Darnitsky district, frightened residents of a dormitory woke up to their rooms with shattered windows and parked cars outside completely burnt out.

Communities have also adopted new energy solutions to cope with winter blackouts, from generators to shared warming points.

Debris from a downed missile in the capital wounded seven people, including a child.

"God, god, god," Maya Pelyukh, a cleaner who lives in the building, said as she looked at her living room covered in broken glass and debris on her bed.

Her windows and door were blown away, with the 50-year-old saying she crawled out from under a door frame.

Some residents outside were still in dressing gowns as they watched emergency workers put out a fire the authorities said had spread over 400 square meters (4,300 square feet).

In the northeastern city of Kharkiv seamstresses were clearing a damaged clothing factory, with a Russian missile hitting nearby.

"The ceilings fell down. Windows were blown out. There are chunks of the road inside," Yulia Barantsova said, as she cleared a sewing machine from dust and rubble.

Severe heat: 5 electricity blackout risks facing the entire U.S., not just Texas

Texas power grid highlights ERCOT reliability strains from extreme heat, climate change, and low wind, as natural gas and renewables balance tight capacity amid EV charging growth, heat pumps, and blackout risk across the U.S.

 

Key Points

Texas power grid is ERCOT-run and isolated, balancing natural gas and wind amid extreme weather and electrification.

✅ Isolated from other U.S. grids, limited import support

✅ Vulnerable to extreme heat, winter storms, low wind

✅ Demand growth from EVs and heat pumps stresses capacity

 

Texas has a unique state-run power grid facing a Texas grid crisis that has raised concerns, but its issues with extreme weather, and balancing natural gas and wind, hold lessons for an entire U.S. at risk for power outages from climate change.

Grid operator the Electric Reliability Council of Texas, or ERCOT, which has drawn criticism from Elon Musk recently, called on consumers to voluntarily reduce power use on Monday when dangerous heat gripped America’s second-most populous state.

The action paid off as the Texas grid avoided blackouts — and a repeat of its winter crisis — despite record or near-record temperatures that depleted electric supplies amid a broader supply-chain crisis affecting utilities this summer, and risked lost power to more than 26 million customers. ERCOT later on Monday lifted the call for conservation.

For sure, it’s a unique situation, as the state-run power grid system runs outside the main U.S. grids. Still, all Americans can learn from Texas about the fragility of a national power grid that is expected to be challenged more frequently by hot and cold weather extremes brought on by climate change, including potential reliability improvements policymakers are weighing.

The grid will also be tested by increased demand to power electric vehicles (EVs) and conversions to electric heat pumps — all as part of a transition to a “greener” future.

 

Why is Texas different?
ERCOT, the main, but not only, Texas grid, is unique in its state-run, and not regional, format used by the rest of the country. Because it’s an energy-rich state, Texas has been able to set power prices below those seen in other parts of the country, and its independence gives it more pricing authority, while lawmakers consider market reforms to avoid blackouts. But during unusual strain on the system, such as more people blasting their air conditioners longer to combat a record heat wave, it also has no where else to turn.

A lethal winter power shortage in February 2021, during a Texas winter storm that left many without power and water, notoriously put the state and its independent utility in the spotlight when ERCOT failed to keep residents warm and pipes from bursting. Texas’s 2021 outage left more than 200 people dead and rang up $20 billion in damage. Fossil-fuel CL00, 0.80% backers pointed to the rising use of intermittent wind power, which generates 23% of Texas’s electricity. Others said natural-gas equipment was frozen under the extreme conditions.

This week, ERCOT is asking for voluntary conservation between 2 p.m. and 8 p.m. local time daily due to record high electricity demand from the projected heat wave, and also because of low wind. ERCOT said current projections show wind generation coming in at less than 10% of capacity. ERCOT stressed that no systemwide outages are expected, and Gov. Greg Abbott has touted grid readiness heading into fall, but it was acting preemptively.

A report late last year from the North American Electric Reliability Corp. (NERC) said the Texas system without upgrades could see a power shortfall of 37% in extreme winter conditions. NERC’s outlook suggested the state and ERCOT isn’t prepared for a repeat of weather extremes.
