Inside CoreWeave's Renewable-Powered Data Centres in Sweden
CoreWeave is expanding its European AI cloud footprint with a new deployment in Sweden, where renewable electricity and energy-efficient infrastructure will be core priorities.
The company has signed a co-location agreement with Swedish data centre operator Conapto to establish two facilities in Stockholm, providing additional AI cloud capacity for customers across Europe while supporting the region's ambitions for low-carbon digital infrastructure.
Capacity is already live at the Stockholm 4 South campus, increasing the availability of high-performance computing resources for AI applications across the European market.
The agreement gives developers access to CoreWeave Cloud, a platform purpose-built for demanding AI workloads.
Combining advanced computing, networking, storage and software orchestration, the platform is designed to help organisations deploy and scale AI applications more efficiently.
Meeting the power demands of AI
Growing adoption of generative AI is driving a sharp increase in demand for energy-intensive computing infrastructure, placing greater emphasis on both reliable electricity supplies and efficient facility design.
To support these workloads, CoreWeave is deploying NVIDIA Blackwell Architecture alongside NVIDIA Vera Rubin Platforms.
The systems are interconnected using NVIDIA Quantum-X800 InfiniBand, providing the bandwidth required for large-scale enterprise AI deployments.
Supporting this technology requires carefully engineered data centre environments.
High-density AI hardware consumes substantial amounts of electricity while producing significant heat, making resilient power infrastructure, advanced cooling and operational redundancy essential to maintaining continuous performance.
By partnering with Conapto, CoreWeave gains access to facilities designed to deliver the dependable power, cooling and uptime required for these high-performance AI clusters.
“Sweden has been central to CoreWeave’s European strategy since our first continental investment,” says Sachin Jain, Chief Operating Officer at CoreWeave.
“Conapto’s local expertise and sustainable energy profile allows us to provide our customers what they need: urgent high performance AI compute with the reliability and environmental credentials that enterprise AI deployments demand.”
Renewable electricity and heat recovery
Energy sustainability remains a defining issue for the expanding data centre sector, with operators increasingly seeking ways to reduce emissions while meeting rising electricity demand.
Conapto's Stockholm campuses run entirely on renewable energy, supporting European efforts to accelerate the adoption of cleaner technologies while lowering the environmental impact of AI infrastructure.
Alongside renewable power, the facilities capture excess heat generated by AI servers instead of allowing it to go to waste.
That thermal energy is transferred into Stockholm's district heating network, allowing it to be reused to help heat homes and buildings across the city.
"We're excited to partner with CoreWeave to support the rapidly growing demand for their AI cloud platform," says Håkan Björklund, CEO at Conapto.
"CoreWeave is at the forefront of AI innovation, and we're proud to provide the resilient, high-density infrastructure needed to power their next phase of growth.
“Combined with our commitment to 100% renewable energy and heat recovery to Stockholm's district heating network, this partnership demonstrates how advanced AI infrastructure and sustainability can go hand in hand."
Expanding energy capacity for global growth
The partnership expands CoreWeave's European footprint to eight operational sites and adds to the company's growing global infrastructure estate.
As of 31 March 2026, CoreWeave operated 49 data centres worldwide, managing more than 1GW of active power alongside over 3.5GW of contracted power to support future growth in AI computing.
That expanding energy capacity enables the company to deliver services to nine of the world's 10 leading foundation model providers.
CoreWeave also continues to benchmark the performance of its infrastructure through independent testing, recording industry-leading MLPerf results while holding Platinum rankings in both SemiAnalysis ClusterMAX 1.0 and 2.0. Independent inference benchmarking by Artificial Analysis additionally places the company first for inference speed and price-performance for Moonshot AI's Kimi K2.6.
