Power Generation

We generate electricity when renewable generation cannot and demand is at its greatest

The challenges created by the increasing electrification of society combined with the requirements for low carbon power generation will need a multi discipline approach to maintain security of power supply. The challenges caused by renewable power were never foreseen when the grid was designed and built 50 years ago, but now they must be met. Flexible capacity is expected to increase by nearly 340% over the next 20 years and half of this will be reciprocating engines with an estimated 11GW operational capacity by 2030, so the installations we develop, build and manage are central to the energy transition process.


The UK government has a strong commitment to sustainable energy sources. Solar and wind are each prone to unpredictable drops in output, such as when the wind suddenly falls or clouds cover the sun. When this happens, the grid needs replacement energy to plug the gaps and keep the lights on.

Our first gas-powered balancing plant was built in just three months in 2015. With new software and new engineering, it was the blueprint for the next generation of balancing plant operated by us. We have built over £150 million worth of new gas plants across the UK. These natural gas plants can start and be online in 30 seconds, which is unique in the global market.

Since the Paris climate conference, the world is set on a carbon-reduction path by whatever viable means. The constant watchword, however, has to be reliability. Public confidence and business performance both rely on consistency of supply.
