Google – Workflows to Gromstul

At Gromstul outside Skien, Google is planning one of the world’s largest data centers. During the construction phase – which can last from five to ten years – you need robust, continuous power for thousands of workers and tons of infrastructure. Here, nothing waits in line.

Møre Trafo supplies six complete substations with 1,250 kVA transformers to the site, including insulated housing, switchgear, and metering cell. The substations connect to Lede’s supply grid and ensure stable power for the construction work throughout the entire building phase.

Global digital infrastructure is built in Norway, and the construction phase demands no downtime.

• Continuous power through a long construction phase– estimated 5–10 years
• High power for parallel construction activities– infrastructure, blasting and building
• Connection to Lede’s grid – precise technical requirements from the grid owner

Google secured the roughly 2,000-decare site in 2019. The project was formally approved in 2025, with the data center scheduled to go live in 2026. In the meantime, the entire energy infrastructure is being built, with Møre Trafo supplying the critical working power.

Tailor-Made for Demanding Construction Sites

• 6 complete substations
• 1,250 kVA transformers
• Insulated housing with switchgear and metering cell
• Connection to Lede’s supply grid

The solution is delivered through the local contractor Laugstol AS and serves as the basic energy infrastructure for the entire construction project.

• 6 substations in operation – secure power for the entire construction phase
• Critical infrastructure in place from day one of Norway’s largest industrial project
• The delivery shows Møre Trafo’s role in critical public and industrial projects

The data center represents multi-billion investments and will employ several thousand people during construction.

Møre Trafo’s delivery is part of the core infrastructure that makes the project possible.
