Green Mission & Energy Statement

Green Mission

Stelliums mission is to minimize our carbon footprint, employ sustainable processes and materials, decrease our reliance on fossil fuels and create a resilient and efficient data centre. We can most effectively deliver this mission through coordinating our sustainable activities closely with our clients and supply chain to create a holistic community solution

Green Energy

Stellium have been delivering 100% renewable electrical energy as standard to our clients for a number of years. Our current energy supply agreements are accredited by OFGEM under the Renewable Energy Guarantees of Origin (REGO) scheme for delivery of renewable energy. We continue to work with our energy supply chain to develop a wide range of renewable energy products and dedicated source traceability combined with efficiency and best value for money.

Data Centre energy supply facts:

  • Stellium have been successful in joining the UK Gov. CCA tariff relief scheme. This involves commitment to the direct reduction of energy within agreed timescales. This is independently audited for validation.
  • Stellium have developed (with a service partner) a scheme to go-off national grid power during defined periods of grid peak loads. This is a scalable solution which will grow with the load development of the DC. This will provide substantial support to the grid, create tangible tariff relief and contribute considerably to our ISO 14001 Environmental Management scope 1.
  • Stellium DC Campus supplied directly via dual diverse service from 275kV National Grid.
  • Onshore substation for the Blyth Offshore Demonstrator Wind Farm (currently operational with 5 turbines generating over 40MW capacity with potential to expand
  • North Sea Link Project – UK / Norway interconnector – 1400MW Hydro Power
  • SSE Renewables and Equinor are currently constructing the world’s biggest offshore wind project’ Dogger Bank, which comprises of three 1.2GW sites. The Port of Tyne in Newcastle is to become the onshore base for the wind farm, which is expected to provide renewable electricity for more than 4.5 million UK homes and businesses when it is fully operational.

Green Innovation and Design

Stellium have deployed design and operational innovations to help us achieve higher energy efficiency within our data centre such as:

  • Excellent BREEAM rating
  • P.U.E of 1.24
  • Free Cooling Chillers
  • Direct and indirect cooling to accommodate high efficiency, high power density rack requirements
  • VSC (Variable Speed Control) on all pumps/fans to optimise energy usage
  • DCIM (Datacenter Integrated Management)
  • Adaptive Control Systems
  • ASHRAE thermal guidelines
  • Cold/hot aisle containment
  • Energy-efficient lighting systems
  • High Temperature Chilled Water Set Points


Stellium closely monitor the developing Covid-19 situation. Given the risks it creates Stellium has as a contingency already activated its Business Continuity Plan ensuring we are prepared in advance to maintain normal services. Stellium relies on the UK Government and NHS advice in shaping its response and continues to assess the measures it has in place and how these need to be adjusted as circumstances change.
