Energy storage in the UK has primarily been provided in the past by medium-term storage technologies (comprising both conventional hydro and pumped storage) that have been used for energy arbitrage, initially for balancing the fixed base load generation of nuclear stations.  Following the expansion of gas turbine generation in the 90s, which could fulfill this role more easily, this resulted in pumped storage being used increasingly for maintaining grid stability by providing ancillary services under the National Grid ESO balancing mechanism.  More recently, solid-state batteries have entered the market as another technology capable of providing short-term balancing services.

However, the recent expansion of renewable generation, particularly wind and solar, has resulted in greater intermittent generation and hence the need to provide increased operating reserve in both the short-term and longer term.  While pumped storage plants can currently provide medium-term and short-term ‘shallow’ storage, over several days, there is currently insufficient reservoir storage capacity at these plants to provide the necessary long-term ‘deep’ storage, over several days or even weeks, needed for balancing of renewables.

There is thus a perceived need for increased energy storage both to meet the short-term (shallow) storage requirements of the NG balancing mechanism as well as longer term (deep) storage for improved balancing of intermittent renewables.  This could be provided by a combination of both long-term and medium-term energy storage technologies including pumped storage, on the supply side, with short-term storage technologies such as batteries, located on the demand side.

 This presentation investigates the options open to the UK power sector and how the development of further pumped storage could save up to £10 billion in long term generation costs in order to meet the UK’s net-zero emissions targets.

Senior Associate Director, Jacobs UK, Hydropower Global Technical Lead

Simon Bailey

Simon has over 30 years' experience in hydropower, dams and water resources development worldwide. From his early design experience for the 300MW pumped storage project by the side of Loch Ness in the Scottish Highlands, Simon has been involved in a wide range of major hydropower projects including Lar dam in Iran, the Victoria dam and hydroelectric project and Samanalawewa hydropower projects in Sri Lanka, optimisation studies for Phase I of the Lesotho Highlands Water project including optimising the heights of the 5 dams that make up the project, including the various transfer tunnels and hydropower plant.  Later, he was involved in planning and optimisation of the Komati basin project in Swaziland including modelling studies of the Dead Sea and the proposed Red Sea/Dead Sea canal with associated hydropower and desalination plant, as well as a range of studies on the water resources of the Syr Darya and Amu Darya rivers in Central Asia, to optimise water use for irrigation and hydropower, as part of a strategy for saving the North Aral Sea.

Simon has specialised in water resource and hydropower planning for international development agencies and governments in many countries including studies in Angola, Ethiopia, Uganda, Zimbabwe, Sudan, Lesotho, South Africa, Swaziland, Lebanon, Jordan, Turkey, Syria, Iran, Oman, Albania, Macedonia, Bosnia Herzegovina, Poland, Kazakhstan, Uzbekistan, Sri Lanka and the UK.

He has recently authored a paper on a strategy for long-term energy storage and the future role for pumped storage to meet the UK’s net-zero emissions targets by 2050.
