How Much Pumped Storage Hydro Will Be Operational In The UK By 2030?

Pumped Storage Hydro is the Bank of England-standard for energy storage.

I asked Google AI, the question in the title of this post and received this answer.

The UK currently has approximately 3 GW (roughly 26-28 GWh) of operational pumped storage hydro (PSH) capacity. By 2030, this capacity is expected to increase, driven by new projects in the pipeline that aim to meet a government goal of up to 8 GW of long-duration energy storage by that year.

Key Projects Expected Online by 2030-2031:

Coire Glas (SSE): A major project in Scotland with a planned capacity of 1.3 GW / 30 GWh, expected to be operational around 2030–31.

Cruachan Expansion (Drax): A 600MW plant in Scotland that has received approval, with construction expected to contribute to the 2030 goal.

Glenmuckloch: Projected to be operational by 2029. In 

Other Developments:

Total Pipeline: Developers have identified up to 10 GW of potential projects in the Scottish Highlands and Wales, though not all will be operational by 2030.

Future Growth: The total installed capacity of PSH is expected to grow significantly, with one projection suggesting a rise from 26.7 GWh currently to over 122 GWh by 2034.

To support these projects, the UK government has confirmed a “cap and floor” investment framework to stimulate development of long-duration energy storage (LDES).

For a relatively small island we do seem to be an ideal place to develop pumped storage hydro!

In The Coire Glas Pumped Storage Scheme, I give more details of this scheme.

The Glenmuckloch Pumped Storage Scheme

In The Glenmuckloch Pumped Storage Scheme, I give more details of this scheme, which is based on a disused open cast coal mine.

Addition Of Pumped Storage Hydro By 2030

This looks to be around 5 GW, but it is just a foretaste of the shape of things to come!

MoU Signed To Develop Scottish Highlands As Offshore Wind And Renewables Hub

The title of this post, is the same as that of this article on offshoreWIND.biz.

This is the sub-heading.

The Inverness and Cromarty Firth Green Freeport (ICFGF) has signed a Memorandum of Understanding (MoU) with the UK and Scottish governments and The Highland Council, creating a formal framework for cooperation in developing the Highlands as a major international hub for the offshore wind and renewable energy sector

This is the first paragraph.

The agreement is said to unlock GBP 25 million (approximately EUR 29 million) in funding from the UK government, which ICFGF plans to use to support the delivery of significant infrastructure projects and its partner ports.

These are some points from the rest of the article.

  • Inverness and Cromarty Firth Green Freeport aims to bring up to 11,300 jobs to the Highlands.
  • Significant investments we’ve already include the Sumitomo subsea cable plant at Nigg and the Haventus energy transition facility at Ardersier.
  • Over the next 25 years, ICFGF is expected to attract over GBP 6.5 billion of investment.
  • The Green Freeport includes three tax sites: Cromarty Firth, which includes Port of Nigg, Port of Cromarty Firth, and Highland Deephaven.
  • Ardersier Energy Transition Facility has secured a GBP 100 million joint credit facility to create nationally significant infrastructure for industrial-scale deployment of fixed and floating offshore wind.
  • It has placed contracts with more than 110 local firms as part of the development.

These investments will setup the long-term future of Inverness and the Highlands of Scotland.

The Inverness and Cromarty Firth Green Freeport (ICFGF) has this web site, with these messages on the home page.

Europe’s strategic hub for renewable energy

Transforming the Highland economy and delivering national energy security

Conclusion

This area will become one of the most vibrant places in Europe.
