Six California cities, concerned about global warming and greenhouse gas emissions, are refusing to allow a third coal-fired generating unit to be built at the Intermountain Power Project near Delta.

Their action promises to pit California's tough new environmental laws and the state's commitment to rolling back greenhouse emissions against the interests of thousands of Utah consumers who eventually may need the electricity that a third generating unit could provide.

The six California cities take 75 percent of the electricity generated at the IPP. As a result, their votes far outweigh those of the 23 Utah municipal members, which are represented by the Utah Associated Municipal Power Systems, or UAMPS, and Rocky Mountain Power.

The whole matter could wind up in court, with the Utah municipalities and Rocky Mountain Power vowing to do whatever is necessary to clear the way for the new unit.

"We have no problem if they don't want to participate in building that unit," said spokesman Dave Eskelsen of Rocky Mountain Power, which takes 4 percent of the power produced by IPP and is interested in getting more to meet its customers' demands.

Rocky Mountain Power, however, considers it improper for those California cities - Los Angeles, Pasadena, Anaheim, Burbank, Glendale and Riverside - to block needed generating capacity in Utah to satisfy California's environmental laws.

The IPP is an 1,800-megawatt, coal-fired generating plant operated by the Salt Lake City-based Intermountain Power Agency, which represents the interests of the 36 municipalities, electrical cooperatives and investor-owned utilities that get power from the facility.

The proposed third unit, if it is built, would add another 900 megawatts of generating capacity. One megawatt is enough to provide power to 750 to 1,000 homes.

Reed Searle, general manager of the IPA, said his organization has no choice but to dump development plans for the third unit because of the six California cities' refusal to cooperate with those who want it built.

"We have no doubt that they (Rocky Mountain Power and the 23 Utah municipalities) will need the power," said Searle, whose organization finds itself in the middle of a high-stakes dispute among its members. "Unfortunately, we can't get the support to get construction of that third unit done."

IPA had expected to be able to get signed construction contracts for the third unit by the end of the year, Searle said.

Searle said that in his 19-year history with IPA, it has been very rare when there wasn't a unanimous vote among stakeholders on how the plant should be run.

"It was a major shock to us," Searle said of the California cities' decision. "And I'm sure it has a lot to do with that state's new initiatives to fight global warming."

Among California's new environmental initiatives is the Global Warming Solutions Act of 2006, a law signed by Gov. Arnold Schwarzenegger. It sets up a statewide program to cap all greenhouse gas emissions from major industries in California and includes penalties for noncompliance.

Spokesman Joe Ramallo of the Los Angeles Department of Water and Power, which takes nearly 45 percent of the power produced from the IPP, declined to discuss his city's dispute with Rocky Mountain Power and UAMPS.

However, his agency announced in 2003 that it wasn't going to buy any more electricity generated from coal.

"We've committed that 20 percent of the power we provide will come from renewable resources by 2010 and 35 percent by 2025. Right now we're at 9 percent and climbing," Ramallo said.

Winter Storm Leaves Many In Texas Without Power And Water

Texas Power Grid Crisis strains ERCOT as extreme cold, ice storms, and heavy snow trigger rolling blackouts, load shedding, and boil-water notices, leaving millions without electricity while frozen turbines and low gas pressure hinder generation.

 

Key Points

A statewide emergency of outages and boil-water notices as ERCOT battles extreme cold and load shedding.

✅ Millions without power; ERCOT orders load shedding

✅ Boil-water notices in Austin, Houston, Fort Worth

✅ Frozen equipment, low gas pressure, extreme cold disrupt supply

 

Nearly 3 million homes and businesses in Texas remain without power, some for a third consecutive day, as severe winter weather continues to pummel the state, forcing some localities to issue boil-water notices and urge residents to reduce their electricity usage.

Heavy snowfall, ice storms and bitter temperatures continue to put an enormous strain on the state's power grid. This as the Electric Reliability Council of Texas (ERCOT), which manages roughly 75% of the Texas power grid, announced Wednesday morning that some 600,000 households had power restored overnight.

That still left another 2.7 million customers having to endure extreme cold with no indication of when the thaw would break in their homes.

"We know millions of people are suffering," ERCOT's president and CEO, Bill Magness, said in a statement Wednesday. "We have no other priority than getting them electricity. No other priority."

ERCOT also said Wednesday that it was urging local utilities to shed some 14,000 megawatts of load, which translates to roughly 2.8 million customers, to prepare for a sudden increase in demand.

"The ability to restore more power is contingent on more generation coming back online," said Dan Woodfin, the senior director of ERCOT's system operations, and utility supply-chain constraints can further complicate repair timelines for some utilities.

He said that about 185 generating units were offline, stemming from a range of factors including frozen wind turbines, low gas pressure and frozen instrumentation.

But many Texans feel abandoned by the council and power companies and they are lashing out at the local face of utilities.

The City of Austin's community-owned electric utility, Austin Energy, issued a tweet saying crews that are working to restore power are facing harassment.


"Our crews have been working 24/7 and in these elements," Austin Energy announced. "Some of our crews are reporting incidents of harassment, threatening them and even throwing things at them."

Officials pleaded with the public to remain calm. "I know people are extremely frustrated. But please, I bet of you, do not approach AE crews."

Parts of Austin are under a boil water notice, which Austin Water Director Greg Meszaros attempted to explain during a press briefing Wednesday afternoon.

"There was a large main break in that area, maybe multiple ones. We're seeing main breaks and pipes bursting by the tens of thousands. Our entire system is under stress," Meszaros said.

It's not just the Lone Star State that is being crippled by the arctic blast, with a deep freeze slamming the energy sector across the country.

At least two dozen people have died this week from weather-related incidents, according to The Associated Press.

The National Weather Service reports that more than 100 million Americans are being affected by extreme winter weather from the south central U.S. to the East Coast, including Arkansas, Louisiana, Mississippi, North Carolina, Virginia and West Virginia, and analysts warn of blackout risks nationwide during extreme heat as well.

The National Weather Service adds that cold temperatures over the nation's heartland will begin to "moderate in the coming days" but that many parts will remain 20 to 35 degrees below normal in the Great Plains, Mississippi Valley and lower Great Lakes region.

"Potential is increasing for significant icing across portions of the Mid-Atlantic, which will be very impactful, especially for those hardest hit from the previous ice storm," the National Weather Service tweeted Wednesday.

Texas Gov. Greg Abbott railed against ERCOT, and Elon Musk criticized the agency as unreliable, saying the utility "has been anything but reliable over the past 48 hours."

"This is unacceptable," Abbott added, as residents were facing rotating intentional power outages. The governor issued an executive order that will add reforms for how the power grid is managed, including grid reliability improvements under discussion, as an emergency legislative item for the state legislature to review.

The rolling power outages forced Fort Worth to extend a boil-water notice for roughly 212,000 residents. Officials said the outages affected the city's systems that both treat water and move it to customers.

Fort Worth officials said nine other localities that purchase water from the city are also affected, including Haslet, Keller, Lake Worth and Northlake.

Officials in Houston also issued a boil-water notice for the city's residents Wednesday.

"Do not drink the water without boiling it first," Houston Public Works said from its official Twitter account. "Bring all water to a boil for at least two minutes. Let it cool before using."

In Harris County, which includes Houston, Judge Lina Hidalgo warned residents about extended power outages.

"Let me give it to you straight, based on the visibility I have: Whether you have power or not right now, there is a possibility of power outages even beyond the length of this weather," Hidalgo said, according to Houston Public Media.

The NPR member station adds that county officials have also reported more than 300 cases of carbon monoxide poisoning since Monday as residents going without electricity search desperately for alternative sources of warmth.

"In no uncertain terms, this is a public health disaster and a public health emergency," Samuel Prater, an emergency physician at Memorial Hermann-Texas Medical Center, said at a news briefing Tuesday.

Prater warned residents that over the last 24 hours, emergency officials "have seen a striking increase in the number of cases related to improper heating sources," including indoor use of generators, charcoal grills, campfire stoves and other devices that are being used to warm homes. The result, he added, is carbon monoxide poisoning of entire families.

"If you think you or a loved one has become ill from carbon monoxide poisoning, first thing you need to do is get outside to fresh air," Prater said.

A woman and an 8-year-old girl are among those who have reportedly died from carbon monoxide poisoning after a vehicle was left running inside a garage in an attempt to generate heat, according to Houston's ABC affiliate.

As Texas endures further weather-related issues, including road and highway closures, there's a renewed focus on how the Texas power grid has failed, and why the grid is facing another crisis amid this prolonged cold.

The Texas electrical grid is "facing conditions that it was not designed for," said Emily Grubert, a professor at Georgia Tech whose expertise includes electric networks.

"These are really extreme conditions for the Texas grid. It's very cold. It's cold across the entire state, and it's cold for a long time. This does not happen very often," she said in an interview with NPR's Morning Edition.

"Demand really spiked both in the electricity and the natural gas systems at the same time as a lot of the generators were not able to operate because of those cold conditions, and not being prepared for it is really what's going on," Grubert said. "But a lot of grids are susceptible to really, really major failures when they are this far outside of design conditions."

Abbott told Fox News on Tuesday that with weather-related shutdowns in wind and solar energy, which account for more than 10% of the state's grid, renewable energy is partly to blame for the Texas power crisis, even as he later touted the grid's readiness heading into the fall.

"It just shows that fossil fuel is necessary for the state of Texas as well as other states to make sure that we'll be able to heat our homes in the wintertime and cool our homes in the summertime," Abbott said.

But Grubert said that "coal, gas and nuclear actually shut down because of the extreme cold due to things like instruments freezing, et cetera. So I think the overall point here is all of the fuels were really, really struggling."

Georgia Power customers to see $21 reduction on June bills

Georgia Power June bill credit delivers PSC-approved savings, lower fuel rates, and COVID-19 relief for residential customers, driven by natural gas prices and 2018 earnings, with typical 1,000 kWh users seeing June bill reductions.

 

Key Points

A PSC-approved one-time credit and lower fuel rates reducing June bills for Georgia Power residential customers.

✅ $11.29 credit for 1,000 kWh usage on June bills

✅ Fuel rate cut saves $10.26 per month from June to September 2020

✅ PSC-approved $51.5M credit based on Georgia Power's 2018 results

 

Georgia Power announced that the typical residential customer using 1,000-kilowatt hours will receive an $11.29 credit on their June bill, reflecting a lump-sum credit model also used elsewhere.

This reflects implementation of a one-time $51.5 million credit for customers, similar to Gulf Power's bill decrease efforts, approved by the Georgia Public Service Commission, as a result of

Georgia Power's 2018 financial results.

Pairing the June credit with new, lower fuel rates recently announced, the typical residential customer would see a reduction of $21.55 in June, even as some regions face increases like Pennsylvania's winter price hikes elsewhere.

The amount each customer receives will vary based on their 2018 usage. Georgia Power will apply the credit to June bills for customers who had active accounts as of Dec. 31, 2018, and are still active or receiving a final bill as of June 2020, and the company has issued pandemic scam warnings to help customers stay informed.

Fuel rate lowered 17.2 percent

In addition to the approved one-time credit in June, the Georgia PSC recently approved Georgia Power’s plan to reduce its fuel rates by 17.2 percent and total billings by approximately $740 million over a two-year period. The implementation of a special interim reduction will provide customers additional relief during the COVID-19 pandemic through even lower fuel rates over the upcoming 2020 summer months. The lower fuel rate and special interim reduction will lower the total bill of a typical residential customer using an average of 1,000-kilowatt hours by a total of $10.26 per month from June through September 2020.

The reduction in the company’s fuel rate is driven primarily by lower natural gas prices, even as FPL proposed multiyear rate hikes in Florida, as a result of increased natural gas supplies, which the company is able to take advantage of to benefit customers due to its diverse generation sources.

February bill credit due to tax law savings

Georgia Power completed earlier this year the third and final bill credit associated with the Tax Cuts and Jobs Act of 2017, resulting in credits totaling $106 million. The typical residential customer using an average of 1,000 kilowatt-hours per month received a credit of approximately $22 on their February Georgia Power bill, a helpful offset as U.S. electric bills rose 5% in 2022 according to national data.

Told "no" 37 times, this Indigenous-owned company brought electricity to James Bay anyway

Five Nations Energy Transmission Line connects remote First Nations to the Ontario power grid, delivering clean, reliable electricity to Western James Bay through Indigenous-owned transmission infrastructure, replacing diesel generators and enabling sustainable community growth.

 

Key Points

An Indigenous-owned grid link providing reliable power to Western James Bay First Nations, replacing polluting diesel.

✅ Built by five First Nations; fully Indigenous-owned utility

✅ 270 km line connecting remote James Bay communities

✅ Ended diesel dependence; enabled sustainable development

 

For the Indigenous communities along northern Ontario’s James Bay — the ones that have lived on and taken care of the lands as long as anyone can remember — the new millenium marked the start of a diesel-less future, even as Ontario’s electricity outlook raised concerns about getting dirtier in policy debates. 

While the southern part of the province took Ontario’s power grid for granted, despite lessons from Europe’s power crisis about reliability, the vast majority of these communities had never been plugged in. Their only source of power was a handful of very loud diesel-powered generators. Because of that, daily life in the Attawapiskat, Kashechewan and Fort Albany First Nations involved deliberating a series of tradeoffs. Could you listen to the radio while toasting a piece of bread? How many Christmas lights could you connect before nothing else was usable? Was there enough power to open a new school? 

The communities wanted a safe, reliable, clean alternative, with Manitoba’s clean energy illustrating regional potential, too. So did their chiefs, which is why they passed a resolution in 1996 to connect the area to Ontario’s grid, not just for basic necessities but to facilitate growth and development, and improve their communities’ quality of life. 

The idea was unthinkable at the time — scorned and dismissed by those who held the keys to Ontario’s (electrical) power, much like independent power projects can be in other jurisdictions. Even some in the community didn’t fully understand it. When the idea was first proposed at a gathering of Nishnawbe Aski Nation, which represents 49 First Nations, one attendee said the only way he could picture the connection was as “a little extension cord running through the bush from Moosonee.” 

But the leadership of Attawapiskat, Kashechewan and Fort Albany First Nations had been dreaming and planning. In 1997, along with members of Taykwa Tagamou and Moose Cree First Nations, they created the first, and thus far only, fully Indigenous-owned energy company in Canada: Five Nations Energy Inc., as partnerships like an OPG First Nation hydro project would later show in action, too. 

Over the next five years, the organization built Omushkego Ishkotayo, the Cree name for the Western James Bay transmission line: “Omushkego” refers to the Swampy Cree people, and “Ishkotayo” to hydroelectric power, while other regions were commissioning new BC generating stations in parallel. The 270-kilometre-long transmission line is in one of the most isolated regions of Ontario, one that can only be accessed by plane, except for a few months in winter when ice roads are strong enough to drive on. The project went online in 2001, bringing reliable power to over 7,000 people who were previously underserved by the province’s energy providers. It also, somewhat controversially, enabled Ontario’s first diamond mine in Attawapiskat territory.

The future the First Nations created 25 years ago is blissfully quiet, now that the diesel generators are shut off. “When the power went on, you could hear the birds,” Patrick Chilton, the CEO of Five Nations Energy, said with a smile. “Our communities were glowing.”

Power, politics and money: Five Nations Energy needed government, banks and builders on board
Chilton took over in 2013 after the former CEO, his brother Ed, passed away. “This was all his idea,” Chilton told The Narwhal in a conversation over Zoom from his office in Timmins, Ont. The company’s story has never been told before in full, he said, because he felt “vulnerable” to the forces that fought against Omushkego Ishkotayo or didn’t understand it, a dynamic underscored by Canada’s looming power problem reporting in recent years. 

The success of Five Nations Energy is a tale of unwavering determination and imagination, Chilton said, and it started with his older brother. “Ed was the first person who believed a transmission line was possible,” he said.

In a Timmins Daily Press death notice published July 2, 2013, Ed Chilton is described as having “a quiet but profound impact on the establishment of agreements and enterprises benefitting First Nations peoples and their lands.” Chilton doesn’t describe him that way, exactly. 

“If you knew my brother, he was very stubborn,” he said. A certified engineering technologist, Ed was a visionary whose whole life was defined by the transmission line. He was the first to approach the chiefs with the idea, the first to reach out to energy companies and government officials and the one who persuaded thousands of people in remote, underserved communities that it was possible to bring power to their region.

After that 1996 meeting of Nishnawbe Aski Nation, there came a four-year-long effort to convince the rest of Ontario, and the country, the project was possible and financially viable. The chiefs of the five First Nations took their idea to the halls of power: Queen’s Park, Parliament Hill and the provincial power distributor Hydro One (then Ontario Hydro). 

“All of them said no,” Chilton said. “They saw it as near to impossible — the idea that you could build a transmission line in the ‘swamp,’ as they called it.” The Five Nations Energy team kept a document at the time tracking how many times they heard no; it topped out at 37. 

One of the worst times was in 1998, at a meeting on the 19th floor of the Ontario Hydro building in the heart of downtown Toronto. There, despite all their preparation and planning, a senior member of the Ontario Hydro team told Chilton, Martin and other chiefs “you’ll build that line over my dead body,” Chilton recalled. 

At the time, Chilton said, Ontario Hydro was refusing to cooperate: unwilling to let go of its monopoly over transmission lines, but also saying it was unable to connect new houses in the First Nations to diesel generators it said were at maximum capacity. (Ontario Hydro no longer exists; Hydro One declined to comment.)

“There’s always naysayers no matter what you’re doing,” Martin said. “What we were doing had never been done before. So of course people were telling us how we had never managed something of this size or a budget of this size.” 

“[Our people] basically told them to blow it up your ass. We can do it,” Chilton said.

So the chiefs of the five nations did something they’d never done before: they went to all of the big banks and many, many charitable foundations trying to get the money, a big ask for a project of this scale, in this location. Without outside support, their pitch was that they’d build it themselves.

This was the hardest part of the process, said Lawrence Martin, the former Grand Chief of Mushkegowuk Tribal Council and a member of the Five Nations Energy board. “We didn’t know how to finance something like this, to get loans,” he told The Narwhal. “That was the toughest task for all of us to achieve.”

Eventually, they got nearly $50 million in funding from a series of financial organizations including the Bank of Montreal, Pacific and Western Capital, the Northern Ontario Heritage Fund Corporation (an Ontario government agency) and the engineering and construction company SNC Lavalin, which did an assessment of the area and deemed the project viable. 

And in 1999, Ed Chilton, other members of the Chilton family and the chiefs were able to secure an agreement with Ontario Hydro that would allow them to buy electricity from the province and sell it to their communities.

As New Zealand gets serious about climate change, can electricity replace fossil fuels in time?

New Zealand Energy Transition will electrify transport and industry with renewables, grid-scale solar, wind farms, geothermal, batteries, demand response, pumped hydro, and transmission upgrades to manage dry-year risk and winter peak loads.

 

Key Points

A shift to renewables and smart demand to decarbonise transport and industry while ensuring reliable, affordable power.

✅ Electrifies transport and industrial heat with renewables

✅ Uses demand response, batteries, and pumped hydro for resilience

✅ Targets 99%+ renewable supply, managing dry-year and peak loads

 

As fossil fuels are phased out over the coming decades, the Climate Change Commission (CCC) suggests electricity will take up much of the slack, aligning with the vision of a sustainable electric planet powering our vehicle fleet and replacing coal and gas in industrial processes.

But can the electricity system really provide for this increased load where and when it is needed? The answer is “yes”, with some caveats.

Our research examines climate change impacts on the New Zealand energy system. It shows we’ll need to pay close attention to demand as well as supply. And we’ll have to factor in the impacts of climate change when we plan for growth in the energy sector.

 

Demand for electricity to grow
While electricity use has not increased in NZ in the past decade, many agencies project steeply rising demand in coming years. This is partly due to both increasing population and gross domestic product, but mostly due to the anticipated electrification of transport and industry, which could result in a doubling of demand by mid-century.

It’s hard to get a sense of the scale of the new generation required, but if wind was the sole technology employed to meet demand by 2050, between 10 and 60 new wind farms would be needed nationwide.

Of course, we won’t only build wind farms, as renewables are coming on strong and grid-scale solar, rooftop solar, new geothermal, some new small hydro plant and possibly tidal and wave power will all have a part to play.

 

Managing the demand
As well as providing more electricity supply, demand management and batteries will also be important. Our modelling shows peak demand (which usually occurs when everyone turns on their heaters and ovens at 6pm in winter) could be up to 40% higher by 2050 than it is now.

But meeting this daily period of high demand could see expensive plant sitting idle for much of the time (with the last 25% of generation capacity only used about 10% of the time).

This is particularly a problem in a renewable electricity system when the hydro lakes are dry, as hydro is one of the few renewable electricity sources that can be stored during the day (as water behind the dam) and used over the evening peak (by generating with that stored water).

Demand response will therefore be needed. For example, this might involve an industrial plant turning off when there is too much load on the electricity grid.

 

But by 2050, a significant number of households will also need smart appliances and meters that automatically use cheaper electricity at non-peak times. For example, washing machines and electric car chargers could run automatically at 2am, rather than 6pm when demand is high.

Our modelling shows a well set up demand response system could mitigate dry-year risk (when hydro lakes are low on water) in coming decades, where currently gas and coal generation is often used.

Instead of (or as well as) having demand response and battery systems to combat dry-year risk, a pumped storage system could be built. This is where water is pumped uphill when hydro lake inflows are plentiful, and used to generate electricity during dry periods.

The NZ Battery project is currently considering the potential for this in New Zealand, and debates such as whether we would use Site C's electricity offer relevant lessons.

 

Almost (but not quite) 100% renewable
Dry-year risk would be greatly reduced and there would be “greater greenhouse gas emissions savings” if the Interim Climate Change Committee’s (ICCC) 2019 recommendation to aim for 99% renewable electricity was adopted, rather than aiming for 100%.

A small amount of gas-peaking plant would therefore be retained. The ICCC said going from 99% to 100% renewable electricity by overbuilding would only avoid a very small amount of carbon emissions, at a very high cost.

Our modelling supports this view. The CCC’s draft advice on the issue also makes the point that, although 100% renewable electricity is the “desired end point”, timing is important to enable a smooth transition.

Despite these views, Energy Minister Megan Woods has said the government will be keeping the target of a 100% renewable electricity sector by 2030.

 

Impacts of climate change
In future, the electricity system will have to respond to changing climate patterns as well, becoming resilient to climate risks over time.

The National Institute of Water and Atmospheric Research predicts winds will increase in the South Island and decrease in the far north in coming decades.

Inflows to the biggest hydro lakes will get wetter (more rain in their headwaters), and their seasonality will change due to changes in the amount of snow in these catchments.

Our modelling shows the electricity system can adapt to those changing conditions. One good news story (unless you’re a skier) is that warmer temperatures will mean less snow storage at lower elevations, and therefore higher lake inflows in the big hydro catchments in winter, leading to a better match between times of high electricity demand and higher inflows.

 

The price is right
The modelling also shows the cost of generating electricity is not likely to increase, because the price of building new sources of renewable energy continues to fall globally.

Because the cost of building new renewables is now cheaper than non-renewables (such as coal-fired plants), investing in carbon-free electricity is increasingly compelling, and renewables are more likely to be built to meet new demand in the near term.

While New Zealand’s electricity system can enable the rapid decarbonisation of (at least) our transport and industrial heat sectors, international efforts like cleaning up Canada's electricity underline the need for certainty so the electricity industry can start building to meet demand everywhere.

Bipartisan cooperation at government level will be important to encourage significant investment in generation and transmission projects with long lead times and life expectancies, as analyses of climate policy and grid implications underscore in comparable markets.

Infrastructure and markets are needed to support demand response uptake, as well as certainty around the Tiwai exit in 2024 and whether pumped storage is likely to be built.

Our electricity system can support the rapid decarbonisation needed if New Zealand is to do its fair share globally to tackle climate change.

But sound planning, firm decisions and a supportive and relatively stable regulatory framework are all required before shovels can hit the ground.

Ambitious clean energy target will mean lower electricity prices, modelling says

Australia Clean Energy Target drives renewables in the National Electricity Market, with RepuTex modelling and the Finkel Review showing lower wholesale prices and emissions as gas generators set prices less often under ambitious targets.

 

Key Points

Policy boosting low emissions generation to cut electricity emissions and lower wholesale prices across Australia.

✅ Ambitious targets lower wholesale prices through added generation

✅ RepuTex modelling shows renewables displace costly gas peakers

✅ Finkel Review suggests CET cuts emissions and boosts reliability

 

The more ambitious a clean energy target is, the lower Australian wholesale electricity prices will be, according to new modelling by energy analysis firm RepuTex.

The Finkel review, released last month recommended the government introduce a clean energy target (CET), which it found would cut emissions from the national electricity market and put downward pressure on both wholesale and retail prices, aligning with calls to favor consumers over generators in market design.

The Finkel review only modelled a CET that would cut emissions from the electricity sector by 28% below 2005 levels by 2030. But all available analysis has demonstrated that such a cut would not be enough to meet Australia’s overall emissions reductions made as part of the Paris agreement, which themselves were too weak to help meet the central aim of that agreement – to keep global warming to “well below 2C”.

RepuTex modelled the effect of a CET that cut emissions from the electricity sector by 28% – like that modelled in the Finkel Review – as well as one it said was consistent with 2C of global warming, which would cut emissions from electricity by 45% below 2005 levels by 2030.

It found both scenarios caused wholesale prices to drop significantly compared to doing nothing, despite IEA warnings on falling energy investment that could lead to shortages, with the more ambitious scenario resulting in lower wholesale prices between 2025 and 2030.

In the “business as usual scenario”, RepuTex found wholesale prices would hover roughly around the current price of $100 per MWh.

Under a CET that reduced electricity emissions by 28%, prices would drop to under $40 around 2023, and then rise to nearly $60 by 2030.

The more ambitious CET had a broadly similar effect on wholesale prices. But RepuTex found it would drive prices down a little slower, but then keep them down for longer, stabilising at about $40 to $50 for most of the 2020s.

It found a CET would drive prices down by incentivising more generation into the market. The more ambitious CET would further suppress prices by introducing more renewable energy, resulting in expensive gas generators less often being able to set the price of electricity in the wholesale market, a dynamic seen with UK natural gas price pressures recently.

The downward pressure of a CET on wholesale prices was more dramatic in the RepuTex report than in Finkel’s own modelling. But that was largely because, as Alan Finkel himself acknowledged, the estimates of the costs of renewable energy in the Finkel review modelling were conservative.

Speaking at the National Press Club, Finkel said: “We were conservative in our estimates of wind and large-scale solar generator prices. Indeed, in recent months the prices for wind generation have already come in lower than what we modelled.”

The RepuTex modelling also found the economics of the national electricity market no longer supported traditional baseload generation – such as coal power plants that were unable to respond flexibly to demand, with debates over power market overhauls in Alberta underscoring similar tensions – and so they would not be built without the government distorting the market.

“With a premium placed on flexible generation that can ramp up or down, baseload only generation – irrespective of how clean or dirty it is – is likely to be too inflexible to compete in Australia’s future electricity system,” the report said.

“In this context, renewable energy remains attractive to the market given it is able to deliver energy reliability, with no emissions, at low cost prices, with clean grid and battery trends in Canada informing the shift for policymakers. This affirms that renewables are a lay down misere to out-compete traditionally fossil-fuel sources in Australia for the foreseeable future.”

Wind Denmark - summer's autumn weather provides extraordinarily low electricity prices

Western Denmark Negative Electricity Prices stem from wind energy oversupply, grid congestion, and limited interconnector capacity via Nord Pool and TenneT, underscoring electrification needs, renewable integration, special regulation, and system flexibility.

 

Key Points

They are sub-zero power prices from wind oversupply, weak interconnectors, low demand, and balancing needs.

✅ Caused by high wind output, low demand, and export bottlenecks

✅ Limited Nord Pool interconnector capacity depresses prices

✅ Special regulation and district heating absorb excess power

 

A downturn in the cable connection to Norway and Sweden, together with low electricity consumption and high electricity production, has pushed down European electricity prices to a negative level in Western Denmark.

A sign that the electrification of society is urgently needed, says Soren Klinge, head of electricity market at Wind Denmark today.

The heavy winds during the first weekend of July, unlike periods when cheap wind power wanes in the UK, have not only had consequences for the Danes who had otherwise been looking forward to spending their first days at home in the garden or at the beach. It has also pushed down prices in the electricity market to a negative level, which especially the West Danish wind turbine owners have had to notice.

'The electricity market is currently affected by an unfortunate coincidence of various factors that have a negative impact on the electricity price: a reduced export capacity to the other Nordic countries, a low electricity consumption and a high electricity generation, reflecting broader concerns over dispatchable power shortages in Europe today. Unfortunately, the coincidence of these three factors means that the price base falls completely out of the market. This is another sign that the electrification of society is urgently needed, 'explains Soren Klinge, electricity market manager at Wind Denmark.

According to the European power exchange Nord Pool Spot, where UK peak power prices are also tracked, the cable connection to Sweden is expected to return to full capacity from 19 July. The connection between Jutland and Norway is only expected to return to full capacity in early September.

2000 MWh / hour in special regulation

During the windy weather on Monday morning, July 6, up to 2000 MWh / hour was activated at national level in the form of so-called special regulation. Special regulation is the designation that the German system operator TenneT switches off Danish electricity generation at cogeneration plants and wind turbines in order to help with the balancing of the German power system during such events. In addition, electric boilers at the cogeneration plants also contribute by using the electricity from the electricity grid and converting it to district heating for the benefit of Danish homes and businesses.

'The Danish wind turbines are probably the source of most of the special regulation, because there are very few cogeneration units to down-regulate electricity generation. Of course, it is positive to see that we have a high degree of flexibility in the wind-based power system at home. That being said, Denmark does not really get ahead with the green transition, even as its largest energy company plans to stop using coal by 2023, until we are able to raise electricity consumption based on renewable energy.
