Europe’s Ageing Power Plants Set for AI-Driven Data Centre Transformation

/in /tarafından

Big tech firms, including Microsoft and Amazon, are eyeing Europe’s retiring coal and gas plants as prime locations for new data centres — tapping into their existing power grid connections, water infrastructure, and cooling systems to meet surging AI energy demands. Utilities such as Engie, RWE, and Enel see these conversions as a way to offset decommissioning costs, secure lucrative long-term power contracts, and underwrite future renewable projects.

Many of the EU’s and UK’s 153 remaining hard coal and lignite plants are scheduled to close by 2038, joining the 190 that have shut since 2005. Repurposing these sites offers utilities stable, high-margin revenues, with tech companies reportedly paying up to €20/MWh in “green premiums” for low-carbon electricity. Depending on scale — some data centres can require up to a gigawatt — such premiums could translate into contracts worth hundreds of millions to billions of euros over decades.

The approach also addresses one of Europe’s key data centre bottlenecks: grid connection delays, which can stretch over a decade. Converting old plants offers “speed to power,” significantly accelerating deployment timelines. Projects range from retrofitting existing sites to building “energy parks” pairing renewable generation with direct supply to data centres.

Engie is actively marketing 40 potential sites worldwide, including its decommissioned Hazelwood coal plant in Australia, while EDP, EDF, Enel, and Britain’s Drax are pursuing similar strategies. Some developments, such as a planned 2.5 GW facility at a former German coal plant and multiple UK sites, are already in motion — though details remain scarce for security reasons.

Industry analysts say the trend represents a diversification of utility business models, creating new revenue streams and fostering long-term tech–energy partnerships. For hyperscalers, the premium is worth paying if it secures earlier market entry in the AI race.

Huawei aims to expand role in Brazil’s data center market amid pending tax incentives

/in /tarafından

Chinese technology giant Huawei has expressed interest in strengthening its position as a supplier of data center solutions in Brazil, Reuters reported on Thursday. While Huawei clarified it does not plan to invest directly in data centers, the company is keen to provide connectivity, storage, and energy solutions for the growing market.

Huawei’s Latin America and Caribbean Vice President of Public Relations, Atilio Rulli, emphasized the importance of the Brazilian government implementing upcoming tax-break incentives designed to attract tech investments. “We want the government to implement these incentives, which are good for the country, and the time has to be now,” he said.

Brazil, Latin America’s largest economy, is working to build a strong data center industry leveraging its abundant renewable energy resources. The government’s tax-break plan is expected to be sent to Congress soon, according to a finance ministry adviser.

The country has already attracted attention from major players such as ByteDance, TikTok’s parent company, as part of its digital infrastructure expansion.

Huawei reaffirmed its commitment to supporting Brazil’s digital transformation with reliable, scalable, and sustainable data center solutions once government incentives come into force.

America’s Largest Power Grid Struggles to Meet Surging AI and Data Center Demand

/in /tarafından

America’s largest power grid, managed by PJM Interconnection and covering 13 states from Illinois to Tennessee, is facing significant strain as data centers and AI chatbots rapidly increase electricity consumption—outpacing the grid’s ability to build new power plants. This has led to sharp electricity price increases, with bills projected to rise over 20% this summer in some areas.

The rising costs stem from an 800% jump in prices at PJM’s annual capacity auction last year, which sets rates to ensure electricity availability during extreme weather. These price hikes trickle down to consumers and have sparked political and organizational upheaval: Pennsylvania’s governor has threatened to pull the state from PJM, the grid’s CEO announced he will step down, and key board members have been replaced.

The auction is scheduled again soon, with expectations of further price rises, driven by a growing mismatch between supply and demand. Aging power plants are retiring faster than new ones come online, and PJM has delayed auctions and paused accepting applications for new power plants—actions that experts say exacerbate the shortage.

Pennsylvania Governor Josh Shapiro emphasized the need for transparency, speed, and cost control from PJM. The grid operator attributes the supply crunch partly to external factors, such as state policies that closed fossil fuel plants prematurely and soaring demand from data centers, especially in “Data Center Alley” in Northern Virginia.

Although PJM has cleared about 46 gigawatts of new power projects in recent years—enough for 40 million homes—many face delays due to local opposition, supply chain issues, and financing problems. PJM lost more than 5.6 gigawatts of power capacity in the last decade and added only about 5 gigawatts in 2024, less than smaller grids in California and Texas.

Demand from data centers alone is expected to increase by 32 gigawatts by 2030, with AI-related workloads significantly contributing to the surge.

The power crunch intensified after PJM paused processing new power plant applications in 2022, overwhelmed by renewable project requests, and after AI chatbots like ChatGPT gained popularity in 2023, boosting data center energy use. Consumer groups have called for a redo of the 2024 capacity auction, citing unfairly high prices.

In response, PJM implemented reforms including price caps and biannual auctions, and expedited the connection of 51 power projects, but many will not be operational until 2030 or later. For example, the Three Mile Island nuclear plant restart, contracted by Microsoft, won’t come online before 2027.

Experts warn that PJM must improve its processing of new power plant applications to effectively address the supply-demand imbalance and prevent blackouts.
