What Green Horizon Data Centers does

Green Horizon AS is a privately held Norwegian data center developer founded in 2021, headquartered in Naerbo, Norway, building a carrier- and cloud-neutral platform in the Stavanger region of Southwest Norway. The platform is anchored on 100% renewable hydropower, with 96MW of power secured across three sites: the flagship Norway 1 (36MW total / 30MW IT), Norway 2 (12MW, with an additional 8MW tranche available from 2028), and Norway 3 (48MW Tier III). Engineering is optimized for high-density AI, GPU, and HPC workloads with liquid-cooling readiness and a target design PUE of 1.1 at full load. A circular-energy concept enables waste heat export to symbiotic partners including Norway's largest greenhouse, biogas facilities, district heating, and land-based fish farming, with the concept unanimously approved by the local municipality.

The company's product set spans colocation (private data halls on a recurring subscription basis), build-to-suit (custom dedicated environments phased to customer roadmaps), carrier-neutral connectivity (multi-carrier architecture with two meet-me-rooms and diverse entry points for low-latency UK/Europe/US routes), and Critical Environment services (24/7 monitoring, liquid-cooling operations, and physical security). Customers are targeted horizontally across AI/GPU/HPC platforms, hyperscalers and cloud providers, large enterprises, and telecommunications/network providers, with revenue mechanics split between recurring colocation and connectivity subscriptions and one-time build-to-suit deployments. Pricing is quote-based via a dedicated sales team rather than publicly disclosed.

Operationally, Green Horizon is pre-revenue. Norway 1 received formal planning approval in June 2026 following prior zoning approval, with a €300M development budget, construction expected to begin later in 2026, and a target ready-for-service date of H2 2027. Delivery is supported by a contracted ecosystem of partners: BHP, BSE3d, and Holon for development and design; Siemens and CTS Nordics for technical engineering; and CBRE for 24/7 operational support. Leadership is led by founder-CEO Richard Rettedal (previously CEO/CFO of Sekal AS) and CCO Paul Besley, with no institutional equity investors, parent company, or funding rounds disclosed in the source material.
