OnZero to Supply AI Compute Heat to Helsinki District Heating
OnZero Finland Oy, a subsidiary of Vienna-based OnZero Alpha Holdings GmbH, has signed an agreement with Helen Oy, the energy utility owned by the city of Helsinki, to supply recovered waste heat from AI compute operations to Helsinki's district heating network. The 'AI Heat Factory' is expected to deliver up to 525,000 MWh of heat per year, equivalent to the heating demand of around 70,000 apartments. Its liquid-cooled architecture is designed to recover up to 99 percent of waste heat and consume no water on site. Commissioning is planned for 2025. OnZero already operates two smaller Finnish sites and is developing a third in Sweden. Helen, which has used data center waste heat since 2010, plans to end combustion-based energy generation by 2040.

Global Data Center Backlash Threatens AI Infrastructure Investments
Public opposition to data center construction is spreading from the U.S. to Europe and Asia, raising risks for investors. In Europe, over 70 projects were rejected or restricted in early 2026, with significant pushback in Scotland, Denmark, Spain, and the U.K. In South Korea, local residents are protesting data centers near homes, prompting proposed consent requirements and review systems. This backlash has delayed or canceled around $42 billion in European data center investments, compared to $77 billion in the U.S. Industry leaders acknowledge growing community scrutiny but see it as manageable, although costs may rise due to project delays. The AI boom continues, but communities now have significant power to derail large-scale plans.
AI slowdown not 'end of world' for data centers: Digital Realty CEO
Digital Realty CEO Andrew Power asserts that an AI development slowdown, pledged by major AI players Anthropic, OpenAI, and xAI, is not catastrophic for data center real estate. He argues that broader digital transformation and cloud computing growth remain strong demand drivers. The article notes that AI could account for 70% of global data center capacity demand by 2030, requiring nearly $7 trillion in capital outlay according to McKinsey. While stocks of data center REITs like Digital Realty and Equinix slumped, Power emphasizes that the company's funding model and $20 billion development pipeline position it well. JLL's Andrew Batson highlights that future data center growth lies in inference (adoption of AI tools), not just training new models, with only 1 in 4 Americans using AI daily.
Data Center Pushback Could Boost Dividend REITs
The article discusses how community and political backlash against AI data center construction could benefit existing data center REITs. Protests and potential legislation restricting new builds may limit supply, increasing the value of existing facilities. Analysts from Mizuho, Wells Fargo, and Green Street suggest that established REITs like Equinix and Digital Realty, with large land banks and development pipelines, are well-positioned. The article highlights three data center REITs: Digital Realty Trust, Equinix, and Iron Mountain, noting their strong year-to-date performance and dividend yields. PwC projects annual data center spending to rise to $1.8 trillion by 2050, while a recent NBC News poll shows 69% opposition to local data center construction. The piece concludes that while restrictions could slow growth, they also enhance the value of existing capacity.
