Investing in pumped-storage hydroelectricity can have "key benefits" for the UK's energy system, according to a new report.
The 'Benefits of Pumped Storage Hydro to the UK' study sets out 20 key perks of expanding the technology in the UK.
Funded by the Scottish Government, SSE, and ScottishPower, the DNV GL study reveals 24GWh of pumped storage capacity currently contributes to the UK's electricity system, split across four sites largely in Scotland. Planning permission is also in place for another 50GWh worth of projects.
Key benefits include alleviating network congestion costs by storing excess generation in constrained zones for later use, as well as avoiding waste of low carbon electricity during periods of low demand. In addition, pumped storage hydro is the most economical storage technology for the long discharge periods required to contribute to security of supply.
Mike Seaton, SSE's Director of Development, said it is clear that pumped storage plays a "significant role" in making the UK's electricity system more efficient, reliable and secure.
"At a stroke, SSE's consented 30GWh Coire Glas project would more than double the total amount of current pumped storage capacity in the UK," he said.
Hannah Smith, Policy Officer for Scottish Renewables, added: "It is important that government creates the right policy environment to encourage investment.
"We would like to see a more level playing field for pumped storage hydro which reflects the value it can bring to the electricity system."
Energy Minister Paul Wheelhouse has now called on the UK Government to work towards removing investment barriers that prevent new pumped storage hydro projects from being built.
"This report outlines the huge opportunity around pumped storage hydro. This tried and tested technology can support peak demand and effectively store greater levels of electricity at times when renewable energy output is high but demand is low," he said.
"This part of the hydropower industry needs a supportive policy and market framework – such as a 'cap and floor' mechanism, as is used for interconnectors – and I call upon the UK Government to heed calls from the sector and work with the industry and Scottish Government to remove investment barriers that prevent new pumped storage hydro projects being built."
