Georgia Power's Plant Bowen tests new technology

TransAlta Alberta Data Centre integrates AI, cloud computing, and renewable energy, tackling electricity demand, grid capacity, decarbonization, and energy storage with clean power, cooling efficiency, and PPA-backed supply for hyperscale workloads.

Key Points

TransAlta Alberta Data Centre is a planned AI facility powered mostly by renewables to meet high electricity demand.

✅ Targets partner exclusivity mid-year; ops 18-24 months post-contract.

✅ Supplies ~90% power via TransAlta; balance from market.

✅ Anchors $3.5B clean energy growth and storage in Alberta.

TransAlta Corp., one of Alberta’s leading power producers, is moving toward finalizing agreements with partners to establish a data centre in the province, aligned with AI data center grid integration efforts nationally, aiming to have definitive contracts signed before the end of the year.

CEO John Kousinioris stated during an analyst conference that the company seeks to secure exclusivity with key partners by mid-year, with detailed design plans and final agreements expected by late 2025. Once the contracts are signed, the data centre is anticipated to be operational within 18 to 24 months, a horizon mirrored by Medicine Hat AI grid upgrades initiatives that aim to modernize local systems.

Data centres, which are critical for high-tech industries such as artificial intelligence, consume large amounts of electricity to run and cool servers, a trend reflected in U.S. utility power challenges reporting, underscoring the scale of energy demand. In this context, TransAlta plans to supply around 90% of its partner's energy needs for the facility, with the remainder coming from the broader electricity market.

Alberta has identified data centres as a strategic priority, aiming to see $100 billion in AI-related data centre construction over the next five years. However, the rapid growth of this sector presents challenges for the region’s energy infrastructure. Electricity demand from data centres has already outpaced the available capacity in Alberta’s power grid, intensifying discussions about a western Canadian electricity grid to improve regional reliability, potentially impacting the province’s decarbonization goals.

To address these challenges, TransAlta has adopted a renewable energy investment strategy. The company announced a $3.5 billion growth plan focused primarily on clean electricity generation and storage, as British Columbia's clean energy shift advances across the region, through 2028. By then, more than two-thirds of TransAlta’s earnings are expected to come from renewable power generation, supporting progress toward a net-zero electricity grid by 2050 nationally.

The collaboration between TransAlta and data centre developers represents an opportunity to balance growing energy demand with sustainability goals. By integrating renewable energy generation into data centre operations and broader macrogrid investments, Alberta could move toward a cleaner and more resilient energy future.

Medicine Hat Bitcoin Mining Facility drives massive electricity demand and energy use, leveraging natural gas and nearby wind power; Hut 8 touts economic growth, while critics cite carbon emissions, renewables integration, and climate impact.

Key Points

A Hut 8 project in Alberta that mines bitcoin at scale, consuming up to 60 MW and impacting energy and emissions.

✅ Consumes more than 60 MW, rivaling citywide electricity use

✅ Sited by natural gas plant; wind turbines nearby

✅ Economic gains vs. carbon emissions and climate risks

On the day of the grand opening of the largest bitcoin mining project in the country, the weather was partly cloudy and 15 C. On a Friday afternoon like this one, the new facility uses as much electricity as all of Medicine Hat, Alta., a city of more than 60,000 people and home to several large industrial plants.

The vast amount of electricity needed for bitcoin mining is why the city of Medicine Hat has championed the economic benefits of the project, while environmentalists say they are wary of the significant energy use.

Toronto-based Hut 8 has spent more than $100 million to develop the 4½-hectare site on the northern edge of the city. It has 56 shipping containers, each filled with 180 computer servers that digitally mine for bitcoin around the clock.

The company said it has already mined more than 3,300 bitcoins in Alberta, including at its much smaller site in Drumheller. On average, the Medicine Hat facility mines about 20 bitcoins per day. The value of bitcoin can fluctuate daily, but has sold recently for around $9,000.

The bitcoin mining facility is located right beside the city of Medicine Hat's new natural gas-fired power plant and four wind turbines are a short distance away. The bitcoin plant can consume more than 60 megawatts of power, more than 10 times more electricity used by any other facility in the city, according to the mayor.

That's why, in the event of a summer heat wave, the city has provisions in place to pull the plug on the electricity it provides to Hut 8, mirroring utility pauses on crypto loads seen elsewhere, so there won't be any blackouts for residents, according to the mayor.

Still, some say the bitcoin mining industry wastes far too much energy

"It's a huge magnitude when you talk about the carbon emissions," said Saeed Kaddoura, an analyst with the Pembina Institute, an environmental think-tank. "Moving forward, there needs to be some consideration on what the environmental impact of this is."

Medicine Hat owns its own natural gas and electricity generation and distribution businesses. The city leases the land to Hut 8 and the facility employs 40 full-time workers. Add up the economic benefits and the city of Medicine Hat will receive a significant financial boost from the new project, says Ted Clugston, the city's mayor.

Financial details of the city's deal with Hut 8 are not disclosed.

For more than a century, the city has attracted business by offering low-cost energy, and the mayor said this project is no different.

"They could have gone anywhere in the world and they chose Medicine Hat," said Clugston. "[Hut 8] is not here for renewable energy because it is not reliable. They need gas-fired generation and we have it in spades."

Environmental groups are concerned by the sheer amount of energy consumed by bitcoin mining, with some utilities warning they can't serve new energy-intensive customers right now, especially in places like Medicine Hat where most of the electricity is produced by fossil fuels.

The bitcoin system is designed, so only a limited number of the cryptocurrency can be mined everyday. Over time, as more miners compete for a decreasing number of available bitcoins, facilities will have to use more electricity compared to the amount of the cryptocurrency they collect.

"The way the bitcoin algorithm works is that it's designed to waste as much electricity as possible. And the more popular bitcoin becomes, the more electricity it wastes," said Keith Stewart, a spokesperson for Greenpeace.

Stewart questions whether natural gas should be used to produce a digital product.

"If you live in Alberta, you want to have heat and light, those types of things. I don't think bitcoin is a necessity of life for anyone," he said.

The CEO of Hut 8 completely disagrees, arguing the cryptocurrency is essential.  

"Bitcoin was created during the financial crisis. It has really served a purpose in terms of providing the opportunity for people who don't necessarily trust their government or their central banks," said Andrew Kiguel.

Cerro Dominador CSP Plant delivers 110MW concentrated solar power in Chile's Atacama Desert, with 10,600 heliostats, 17.5-hour molten salt storage, and 24/7 dispatchable energy; built by Acciona and Abengoa within a 210MW complex.

Key Points

A 110MW CSP solar-thermal plant in Chile with heliostats and 17.5h molten salt storage, delivering 24/7 dispatchable clean power.

✅ 110MW CSP with 17.5h molten salt for 24/7 dispatch

✅ 10,600 heliostats; part of a 210MW hybrid CSP+PV complex

✅ Built by Acciona and Abengoa; first of its kind in LatAm

A consortium formed by Spanish groups Abengoa and Acciona, as Spain's renewable sector expands with Enel's 90MW wind build activity, has signed a contract to complete the construction of the 110MW Cerro Dominador concentrated solar power (CSP) plant in Chile.

The consortium received notice to proceed to build the solar-thermal plant, which is part of the 210MW Cerro Dominador solar complex.

Under the contract, Acciona, which has 51% stake in the consortium and recently launched a 280 MW Alberta wind farm, will be responsible for building the plant while Abengoa will act as the technological partner.

Expected to be the first of its kind in Latin America upon completion, the plant is owned by Cerro Dominador, which in turn is owned by funds managed by EIG Global Energy Partners.

The project will add to a Abengoa-built 100MW PV plant, comparable to California solar projects in scope, which was commissioned in February 2018, to form a 210MW combined CSP and PV complex.

Spread across an area of 146 hectares, the project will feature 10,600 heliostats and will have capacity to generate clean and dispatachable energy for 24 hours a day using its 17.5 hours of molten salt storage technology, a field complemented by battery storage advances.

Expected to prevent 640,000 tons of CO2 emission, the plant is located in the commune of María Elena, in the Atacama Desert, in the Antofagasta Region.

“In total, the complex will avoid 870,000 tons of carbon dioxide emissions into the atmosphere every year and, in parallel with Enel's 450 MW U.S. wind operations, will deliver clean energy through 15-year energy purchase agreements with distribution companies, signed in 2014.

“The construction of the solarthermal plant of Cerro Dominador will have an important impact on local development, with the creation of more than 1,000 jobs in the area during its construction peak, and that will be priority for the neighbors of the communes of the region,” Acciona said in a statement.

The Cerro Dominador plant represents Acciona’s fifth solar thermal plant being built outside of Spain. The firm has constructed 10 solarthermal plants with total installed capacity of 624MW.

Acciona has been operating in Chile since 1993. The company, through its Infrastructure division, executed various construction projects for highways, hospitals, hydroelectric plants and infrastructures for the mining sector.

Alberta Wind Energy Policy Changes highlight TransAlta's Riplinger cancellation amid UCP buffer zones for pristine viewscapes, regulatory uncertainty, and market redesign debates, reshaping Alberta's renewables investment climate and clean energy diversification plans.

Key Points

UCP rules and market shifts reshaping wind siting, permits, and finance, increasing uncertainty and delays for new projects.

✅ 35-km buffer near pristine viewscapes limits wind siting

✅ TransAlta cancels 300 MW Riplinger project

✅ Market redesign uncertainty chills renewables investment

The winds of change are blowing through Alberta's energy landscape today, and they're not necessarily carrying good news for renewable energy development. TransAlta, a major Canadian energy company, recently announced the cancellation of a significant wind farm project, citing a confluence of factors that create uncertainty for the future of wind power in the province. This decision throws a spotlight on the ongoing debate between responsible development and fostering a clean energy future in Alberta.

The scrapped project, the Riplinger wind farm near Cardston, Alberta, was envisioned as a 300-megawatt facility capable of providing clean electricity to the province. However, TransAlta pointed to recent regulatory changes implemented by the United Conservative Party (UCP) government, following the end of the renewable energy moratorium in Alberta, as a key reason for the project's demise. These changes include the establishment of a 35-kilometer buffer zone around designated "pristine viewscapes," which significantly restricts potential wind farm locations.

John Kousinioris, CEO of TransAlta, expressed frustration with the lack of clarity surrounding the future of renewable energy policy in Alberta. He highlighted this, along with the aforementioned rule changes, as major factors in the project's cancellation. TransAlta has also placed three other power projects on hold, indicating a broader concern about the current investment climate for renewable energy in the province.

The news has been met with mixed reactions. While some residents living near the proposed wind farm site celebrate the decision due to concerns about potential impacts on tourism and the environment, others worry about the implications for Alberta's clean energy ambitions, including renewable energy job growth in the province. The province, a major energy producer in Canada, has traditionally relied heavily on fossil fuels, and this decision might be seen as a setback for its goals of diversifying its energy mix.

The Alberta government defends its changes to renewable energy policy, arguing that they are necessary to ensure responsible development and protect sensitive ecological areas. However, the TransAlta decision raises questions about the potential unintended consequences of these changes. Critics argue that the restrictions might discourage investment in renewable energy and the province's ability to sell clean power to wider markets altogether, hindering Alberta's progress towards a more sustainable future.

Adding to the uncertainty is the ongoing process of redesigning Alberta's energy market. The aim is to incorporate more renewable energy sources, including solar energy expansion across the grid, but the details of this redesign remain unclear. This lack of transparency makes it difficult for companies like TransAlta to make sound investment decisions, further dampening enthusiasm for renewable energy projects.

The future of wind energy development in Alberta remains to be seen. TransAlta's decision to scrap the Riplinger project is a significant development, and it will be interesting to observe how other companies respond to the changing regulatory landscape, as a Warren Buffett-linked developer pursues a $200 million wind project in Alberta. Striking a balance between responsible development, protecting the environment, and fostering a clean energy future will be a crucial challenge for Alberta moving forward.

This situation highlights the complex considerations involved in transitioning to a renewable energy future, where court rulings on wind projects can influence policy and investment decisions. While environmental concerns are paramount, ensuring a stable and predictable investment climate is equally important. Open communication and collaboration between industry, government, and stakeholders will be key to navigating these challenges and ensuring Alberta can harness the power of wind energy for a sustainable future.

EU Electricity Market Reform Opposition highlights nine states resisting an overhaul of the wholesale power market amid gas price spikes, urging energy efficiency, interconnection targets, and EU caution rather than redesigns affecting renewables.

Key Points

Nine EU states reject overhauling wholesale power pricing, favoring efficiency and prudent policy over redesigns.

✅ Nine states oppose redesign of wholesale power market.

✅ Call for efficiency and 15% interconnection by 2030.

✅ Ministers to debate responses amid gas-driven price spikes.

Germany, Denmark, Ireland and six other European countries said on Monday they would not support a reform of the EU electricity market, ahead of an emergency meeting of energy ministers to discuss emergency measures and the recent price spike.

European gas and power prices soared to record high levels in autumn and have remained high, prompting countries including Spain and France to urge Brussels to redesign its electricity market rules.

Nine countries on Monday poured cold water on those proposals, in a joint statement that said they "cannot support any measure that conflicts with the internal gas and electricity market" such as an overhaul of the wholesale power market altogether.

"As the price spikes have global drivers, we should be very careful before interfering in the design of internal energy markets," the statement said.

"This will not be a remedy to mitigate the current rising energy prices linked to fossil fuels markets across Europe."

Austria, Germany, Denmark, Estonia, Finland, Ireland, Luxembourg, Latvia and the Netherlands signed the statement, which called instead for more measures to save energy and a target for a 15% interconnection of the EU electricity market by 2030.

European energy ministers meet tomorrow to discuss their response to the price spike, including gas price cap strategies under consideration. Most countries are using tax cuts, subsidies and other national measures to shield consumers against the impact higher gas prices are having on energy bills, but EU governments are struggling to agree on a longer term response.

Spain has led calls for a revamp of the wholesale power market in response to the price spike, amid tensions between France and Germany over reform, arguing that the system is not supporting the EU's green transition.

Under the current system, the wholesale electricity price is set by the last power plant needed to meet overall demand for power. Gas plants often set the price in this system, which Spain said was unfair as it results in cheap renewable energy being sold for the same price as costlier fossil fuel-based power.

The European Commission has said it will investigate whether the EU power market is functioning well, but that there is no evidence to suggest a different system would have better protected countries against the surge in energy costs, and that rolling back electricity prices is tougher than it appears during such spikes.

PG&E Camp Fire Guilty Plea underscores involuntary manslaughter charges as the utility admits sparking Paradise's wildfire; Butte County prosecution, CAL FIRE findings, bankruptcy oversight, victim compensation trust, and safety reforms shape accountability.

Key Points

The legal admission by PG&E to 84 involuntary manslaughter counts and unlawfully starting the 2018 Camp Fire.

✅ 84 involuntary manslaughter counts; unlawful ignition admitted.

✅ $3,486,950 fine, $500,000 DA costs; no prison terms.

✅ $13.5B victim trust, Paradise and Butte County payments.

California utility Pacific Gas and Electric Company pleaded guilty Tuesday to 84 counts of involuntary manslaughter and one count of unlawfully starting the Camp Fire, the deadliest blaze in the state's history.

Butte County District Attorney Michael L. Ramsey said the "historic moment" should be a signal that corporations will be held responsible for "recklessly endangering" lives.
The 84 people "did not need to die," Ramsey said. He said the deaths were "of the most unimaginable horror, being burned to death."

Before sentencing, survivors will testify Wednesday about the losses of their loved ones, and many have pursued lawsuits against the utility seeking accountability.

No individuals will be sent to prison, Ramsey said.

"This is the first time that PG&E or any major utility has been charged with homicide as the result of a reckless fire. It killed a town," Ramsey said, referring to Paradise, which was annihilated by the blaze.
According to court documents filed in March, the company will be fined "no more than $3,486,950," and it must reimburse the Butte County District Attorney's Office $500,000 for the costs of its investigation into the blaze, and under separate oversight a federal judge ordered dividends to be directed to wildfire risk reduction to prioritize safety.

Among other provisions, PG&E must establish a trust, compensating victims of the 2018 Camp Fire and other wildfires to the tune of $13.5 billion as part of its bankruptcy plan, according to the plea agreement included in a regulatory filing.
It has to pay hundreds of millions to the town of Paradise and Butte County and cooperate with prosecutors' investigation, the plea deal says.
PG&E also waived its right to appeal.

"I have heard the pain and the anguish of victims as they've described the loss they continue to endure, and the wounds that can't be healed," PG&E Corporation CEO and President Bill Johnson said after the plea. "No words from me could ever reduce the magnitude of such devastation or do anything to repair the damage. But I hope that the actions we are taking here today will help bring some measure of peace, including aid through a Wildfire Assistance Program the company announced."

Johnson was in court Tuesday, where Butte County Superior Court Judge Michael Deems read the names of each victim as their photos were shown on a screen, CNN affiliate KTLA reported.
Johnson said the utility would never put profits ahead of safety again. He told the judge that PG&E took responsibility for the devastation "with eyes wide open to what happened and to what must never happen again," KTLA reported.

In March, the utility and the state agreed to bankruptcy terms, which included an overhaul of PG&E's board selection process, financial structure and oversight, with rates expected to stabilize in 2025 as reforms take hold.
According to investigators with the California Department of Forestry and Fire Protection, PG&E was responsible for the devastating Camp Fire.

Electrical lines owned and operated by PG&E started the fire November 8, 2018, CAL Fire said in a news release, after the company acknowledged its power lines may have started two fires that day.

"The tinder dry vegetation and Red Flag conditions consisting of strong winds, low humidity and warm temperatures promoted this fire and caused extreme rates of spread," CAL Fire said.
PG&E had previously said it was "probable" that its equipment started the Camp Fire but that it wasn't conclusive whether its lines ignited a second fire, as CAL Fire alleged.
The power company filed for bankruptcy in January 2019 as it came under pressure from billions of dollars in claims tied to deadly wildfires, and other utilities such as Southern California Edison have faced similar lawsuits.
