  • Global bank Citi puts in place innovative energy efficiency measures to cut energy use by 10% at its London data centre.
  • Project is the first of its kind at a UK data centre.

The UK Green Investment Bank (GIB) has today announced that it is backing its first project in the financial services sector. The investment is being made by GIB’s fund manager Sustainable Development Capital (SDCL).

The project will provide finance for a project to deliver efficient electricity and cooling in a UK data centre owned by global bank Citi. A Combined Cooling and Power (CCP) system will be installed together with energy efficient cooling units and efficiency improvements to the building’s air conditioning system.

It is the first project of its kind at a UK data centre, and the first project of its kind that Citi has undertaken globally.

The project will reduce Citi’s costs and its greenhouse gas emissions. It will make a meaningful contribution to reducing the data centre’s running costs.

The CCP system will generate 71% of the electricity needed to power the data centre in Lewisham, London. It will also provide cooling for the servers housed in the data centre. Citi currently uses mains electricity from the national grid and relies on back-up diesel generators.

Shaun Kingsbury, Chief Executive, UK Green Investment Bank said:

The IT industry is one of the most energy intensive sectors globally, second only to aviation. Energy can represent up to 80% of the cost of running a data centre, so they provide an important opportunity for energy efficiency measures.

I am pleased that we have been able to support the first energy efficiency project at a UK data centre and hope that this is the first of many such projects.

This project makes financial sense, reducing Citi’s energy costs, and makes environmental sense, reducing the data centre’s greenhouse gas emissions. And because of the innovative investment model, it will involve no upfront capital expenditure for Citi as the cost of the project will be paid for out of the energy cost savings achieved.


John Killey, Head of Global Building Operations Group, Citi Realty Services said:

SDCL has developed a solution for Citi that provides us with sustainable on-site cooling and power that requires no upfront capital expenditure and that creates enduring savings in our annual operation costs and supports us in reducing our greenhouse gas emissions. We are delighted to be benefiting from its innovative financial solution that facilitates and funds a world-class service from Clarke Energy and GE.


Business Minister, Matthew Hancock said:

This is a hugely welcome investment from Citi, one of the first of its kind for the banking sector. Reducing energy costs makes sound business sense and shows that businesses across the UK can benefit from making the most of green technology. We’ve already invested £3.8 billion into the Green Investment Bank opening up jobs and paving the way for projects like this one from Citi. But we are committed to going further to make sure the whole system is more efficient.


Jonathan Maxwell, Chief Executive, SDCL said:

This investment delivers an innovative solution for one of SDCL’s core global clients in a critical infrastructure asset. This project demonstrates that energy efficiency can deliver a combination of better financial performance, better environmental performance and better infrastructure solutions.

It has been estimated that the UK data centre industry requires approximately 3 GW of energy each year, making it one of the largest consumers of energy in the economy. The banking and finance sector currently accounts for the greatest percentage of overall UK data centre energy use, closely followed by IT services, media and telecommunications. The UK is the third largest consumer of data centre-related energy in the world behind the US and Japan.


About the project

Total investment: £5.2m

Investors: £2.6m from GIB via the SDCL-managed UK Energy Efficiency Investments Fund, which consists of UK Energy Efficiency Investments 1 and matched funding from private sector co-investors via a parallel fund, UK Energy Efficiency Investments 1A.

Energy generation: 23,680 MWh per annum

CCP capacity: 2.8 MW (via two 1.4 MW systems)

Manufacturer: GE Jenbacher (distributed generation technology)

Operational date: Q4 2015

Installation and Servicing: Clarke Energy (GE’s official distributor for Jenbacher engines in the UK)


James Clarke, Chief Executive Officer, Clarke Energy said:

This will be the first facility that Clarke Energy and GE have delivered in the UK at a data centre. Citi’s CCP facility will demonstrate the potential for energy, carbon and cost savings that can be delivered from high efficiency technology.
