A bridge to our energy future

Uniper owns and operates a diverse portfolio of power and gas assets in the United Kingdom. Our employees use their expertise and experience to deliver a range of wholesale energy products and services from power production to gas supply.

Our services are helping build a bridge to our energy future:

  • Climate protection must go hand-in-hand with security of supply.
  • While new technologies scale up and renewables expand, we provide the insurance policy that keeps the lights on.
  • Uniper offers generation and storage facilities,  providing a backbone of constant and reliable power during the energy transition.

Mike has worked in various engineering and commercial roles since joining the UK electricity industry in 1997.  A chartered electrical engineer, he spent the first years of his career with Midlands Electricity in its networks business, and later in Central Networks after the takeover by E.ON in 2004.  He moved to E.ON’s trading business in Düsseldorf in 2008, where he subsequently held a range of management roles.

A broad portfolio of assets for a secure energy supply

Our generation fleet, which encompasses a range of energy sources like gas and coal, makes a tangible contribution to Britain’s supply security. We own and operate power stations at Connah's Quay, Cottam Development Centre, Enfield, Grain, Killingholme, Ratcliffe-on-Soar, and Taylor's Lane. Find more information about our plant portfolio here.

Uniper is a strong supporter of the transition to a low carbon energy world – and we believe that gas continues to have an important part to play. As part of this commitment, we want to make sure our power plants, like the one at Enfield, can operate more efficiently and flexibly, helping to deliver power when and where it’s needed - cost-effectively complementing renewables. Hear more about our investment plans at Enfield here.

Through our trading activities we make our power production available to the market and provide balancing services to the UK system operator. We also buy and sell natural gas, which is brought to the United Kingdom via pipelines or LNG terminals. We own a stake in BBL, a 235-kilometer gas pipeline between Balgzand in the Netherlands and Bacton in the UK. We also own significant long-term regasification capacity at the Grain LNG terminal in Kent.

In addition, we own and operate a gas storage facility in Holford in Cheshire and two high-pressure gas pipelines, from Theddlethorpe to Killingholme and from Blyborough to Cottam, in Northeast England.

The Uniper Engineering Academy offers purpose-built facilities delivering bespoke training programmes - from gas turbine maintenance to smart meter installation - to match energy business needs anywhere in the world. 600 courses were delivered in 2016 to 4,000 delegates, and this year, the Academy won accreditation as an approved provider under the UK Government’s new apprenticeship levy programme.
