“At Green Mountain, reliability and honesty guide everything we do. We combine knowledge, close collaboration, and real commitment to deliver solutions our customers can trust over time.”
Truls Dishington
Managing Director, Nordics
Green Mountain operates data centers across key locations in Europe, including Norway, the UK, and Germany. We combine renewable energy, efficient design, and reliable operations to deliver scalable infrastructure for businesses with critical workloads.
Our foundation is built on Nordic principles of sustainability and efficiency. With access to renewable energy, a strong operational track record, and a transparent approach to delivery, we support our customers in building future-ready digital infrastructure.
We work closely with our clients to design and deliver solutions that meet their requirements for performance, scalability, and cost predictability. From initial planning to daily operations, our teams ensure consistent quality and reliable outcomes.
Through energy-efficient design, flexible solutions, and a focus on long-term value, we enable our customers to grow with confidence and focus on what matters most: their business.
Reliable operations with full transparency
Green Mountain delivers data center uptime with up to Tier III resilience. We build our facilities to the highest global standards. We are committed to meeting the data center quality and compliance needs of global businesses. We put strong emphasis on operational excellence. Since 2013, we have provided customers with real-time insight into the performance of their data rooms through our award-winning Green Peak platform.
Our approach combines structured processes, experienced teams, and transparent reporting to ensure stable and predictable operations across all sites.
Most importantly, our facilities comply with the data center certifications of the International Organization for Standardization (ISO). ISO standards are the most widely accepted in quality, security, safety, and environmental management. Green Mountain’s compliance with these standards ensures that the products and services we offer meet our customers’ demands and often exceed them.
ISO Data Center certifications
World-class security for your valuable data
Data centers are part of a digital infrastructure critical to our modern society. Green Mountain secures our data centers, employees and business against various threats. We have developed a comprehensive framework for our data center security design, making sure our clients’ data is protected. All sites are protected through multiple layers of security, including access control, surveillance, and dedicated on‑site personnel.
Strong connectivity across key markets
Connectivity is a critical element of a data center and it is all about speed and route diversity. Green Mountain’s facilities are carrier-neutral data centers, offering multiple fiber providers. Consequently, our clients can get the fastest, lowest traffic and most direct route possible.
A common misperception is that Norway is on the far outskirts of Europe. That is to say, high latency times and limited route options. If you rewind 15 years, that was probably true. However, due to recent investments in subsea fiber infrastructure, this is no longer the case. Several new projects have recently been completed, and additional projects are under construction.
When it comes to latency, we can reach 54% of businesses in Europe within 20 ms of round-trip time. And almost 100% within 50ms. For example, London is less than 12 ms from our Rennesøy facility. In other words, our facilities in Norway are not only fit for HPC and backup/recovery workloads. We can also support typical client workloads, such as Content Delivery Networks, Cloud-based applications, and IoT Data Aggregation, to name a few. Looking at the map, Norway has a very strategic location for reaching both continental Europe, the UK, and the US.
Sustainability as a foundation
Sustainability is a core part of how we design and operate our data centers. Through efficient energy use, renewable power and heat reuse initiatives, we support customers in reducing their environmental footprint while maintaining high performance.
How we work
We follow a structured approach to ensure reliable, efficient, and scalable data center delivery. From early design discussions to daily operations, our teams work closely together to meet technical requirements, timelines, and budget expectations. A simplified version of our overall work process is divided into three phases: Design, Build, and Operations.
Design
Tailoring the design to the client’s specific requirements.
Build
Strong track record of delivering projects on time, on budget, and to agreed quality.
Operations
Smart Hands services 24/7/365 by a highly qualified team.
Overall HSE target

At Green Mountain, one goal hangs higher than anything else: all employees, suppliers, and subcontractors should return home without injury. Employees must feel valued and included. We care about people and the environment around us.
For Green Mountain, this is a value choice.
We must be clear about our attitude to health, the environment, and safety. Our behavior must reflect positive attitudes towards HSE. By everyone taking daily responsibility for the HSE work, individually and collectively, we commit ourselves. We must plan and conduct the work to prevent damage to people, the environment, or equipment. No financial or project challenges can outweigh a person’s health and life.
Green Mountain aims to look after the employees in the best possible way throughout the working day. This requires establishing a risk management system for organizational, technical, and human factors.
