What WindCORES does

WindCORES (legally WestfalenWIND IT GmbH & Co. KG, headquartered in Paderborn, Germany) operates data centers physically housed inside the towers of operating wind turbines, drawing electricity directly from on-site generation. The company was conceived as a spin-off concept from WestfalenWIND Group — which manages approximately 170 wind turbines with ~350 MW of installed capacity — and first piloted the approach near Lichtenau in 2019. The core technical architecture integrates IT infrastructure into the reinforced-concrete turbine tower (which doubles as a security enclosure and passive cooling sink), connects via redundant fiber to the Frankfurt internet exchange at up to 400 GBit/s and 3.5 ms latency, and is co-developed with the University of Paderborn's SICP research institute under a registered patent. Operations advertise 99.98% availability and 90%+ wind-power utilization, with each 3 kW rack estimated to avoid roughly 14 tons of CO2 per year.

The commercial offering is a two-line B2B portfolio: (1) windCORES Cloud — subscription-based IaaS with customizable virtual machines, firewalls, VLANs, and Azure peering, configured from small (8 vCPU) to enterprise (180 vCPU) tiers; and (2) windCORES Colocation — physical rack or unit-level hosting inside the turbine facilities. Pricing is quote-based on multi-year contracts, with the value proposition framed around permanently low and stable electricity costs (energy being ~40% of conventional data center OPEX). Go-to-market is enterprise field sales targeting German mid-sized and industrial companies, supplemented by a self-service cloud portal (brise.windcores.cloud) and channel partnerships with IT system houses such as Green IT Das Systemhaus and Netzkultur.

The company is privately held as a brand within the WestfalenWIND Group and has no external venture capital funding. Growth is instead financed through parent-company cash flow, a BMBF-funded GreenHPC/ESN4NW research consortium (€2.5M over three years), and participation in the European IPCEI-CIS Next Generation Cloud Infrastructure and Services initiative. Customers include Zattoo (TV streaming), Netzkultur (software), Christie Data (backup/DR), Lanthan Safe Sky (wind-farm aviation lighting), and Green IT Das Systemhaus (reseller). The firm has won the German Data Centre Prize (2019), the ECN Sustainability Award (2023), the Datacenter Strategy Award (2024), and the German Sustainability Award 2026.

Core offering

WindCORES operates climate-neutral cloud computing and colocation services by housing data center infrastructure directly inside operating wind turbines at the Lichtenau wind farm in Germany. The company provides customizable virtual machines, storage, networking, and rack space powered entirely by on-site generated wind electricity, with direct fiber connectivity to the Frankfurt internet exchange point.

Product overview

WindCORES is a green IT provider offering two integrated service lines: Cloud (IaaS with customizable virtual machines, firewalls, and connectivity) and Colocation (physical rack space in wind turbine facilities). Both services leverage a unique infrastructure model where data centers are housed directly inside wind turbines, providing CO2-neutral computing powered by 100% on-site renewable wind energy. The portfolio includes windCORES I (original single-turbine facility) and windCORES II (multi-level second-generation facility), both featuring direct fiber connectivity to Frankfurt internet hub with up to 400 GBit/s capacity and 3.5ms latency.

Direct peers

• EcoDataCenter: Swedish climate-positive data center operator selling colocation and HPC services to European enterprises with renewable-powered facilities. Comparable in green DC positioning and ESG-led go-to-market.
• Hetzner Online: Germany-based hosting/cloud/colocation provider serving price-sensitive SMEs and mid-market — directly overlapping WindCORES' primary target segment and value proposition (low cost, German data residency, sustainability claims).
• Green Mountain: Norwegian colocation provider running data centers powered almost entirely by hydropower, with similar sustainability-driven, low-PUE value proposition and a focus on European enterprise customers. Closely comparable in positioning, though using hydro rather than wind.
• Cloud&Heat Technologies: German provider of sustainable, water-cooled cloud and data center infrastructure that won the same German Data Centre Prize 'Resource-efficient Data Centres' category in 2019 (with WindCORES taking second place). Direct competitor in climate-neutral/green IT services for the German and EU market.
• Maincubes: European (German-headquartered) colocation provider with multiple data centers in Frankfurt and Amsterdam serving enterprise customers. Comparable target market and product mix (colocation + cloud-adjacent services), though without the wind-turbine integration.

Broad incumbents

• T-Systems (Deutsche Telekom): Subsidiary of Deutsche Telekom providing enterprise cloud, colocation, and managed data center services across Europe — partner in the same IPCEI-CIS consortium as WindCORES. Comparable in regulated enterprise/government cloud customer base.
• OVHcloud: European hyperscale cloud and bare-metal/colocation provider with sustainability programs (water-cooled, recycled hardware). Competes in the same mid-market and sovereign-cloud segments WindCORES targets.
• IONOS: Large German incumbent cloud/hosting provider (United Internet subsidiary) offering a broad portfolio of cloud, server, and colocation products to European SMEs and enterprises. Overlaps with WindCORES on cloud services and German mid-market focus but operates at much larger scale.

Regional players

• NorthC Datacenters: Netherlands-based regional colocation provider with several data centers across the Benelux/DACH region serving enterprise customers. Comparable in regional European colocation positioning and mid-market focus.

Emerging players

• EdgeConneX: Global edge data center operator focused on distributed, low-latency compute close to end users — conceptually adjacent to WindCORES' edge/HPC positioning, though much larger and broader in scope.
