Sustainability Information

Do you have a Green Mission statement?


‘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.’

Is renewable energy used on site?

Yes. Stellium have been delivering 100% renewable electrical energy as standard to our clients for a number of years.

Are your energy supply agreements accredited under OFGEM and REGO?

Yes. Our current energy supply agreements are accredited by OFGEM under the Renewable Energy Guarantees of Origin (REGO) scheme for delivery of renewable energy. Certificates available on request to the Site Operations Director.

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.

Do you deploy any additional carbon reduction / sustainable energy generating practises onsite?


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 data centre.

This will provide substantial support to the grid, create tangible tariff relief and contribute considerably to our ISO 14001 Environmental Management scope

1. This  system involves the installation of a 400kWp rooftop solar system and a 2MW/2.3MWh battery energy storage system. These systems will work together to reduce carbon emissions on the site and to moderate incoming power to reduce the high grid carbon intensity periods of consumption and shift them to low grid carbon intensity periods utilising sophisticated charge and discharge protocols. The systems will reduce costs by shifting power use to low market price periods as well as participating in ancillary services with the grid.

Have you joined the UK Gov. CCA tariff relief scheme?

Yes. 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.
