ENGIE And La Caisse Select GE Vernova For The Next Phase Of The Modernization Of Dinorwig Pumped Storage Hydropower Plant In North Wales, UK
The title of this post is the same as this news item from Engie.
These are the three bullet points.
First Hydro Company – a 75:25 joint venture between ENGIE and La Caisse, has selected GE Vernova for the modernization/replanting of the first two units of the Dinorwig pumped storage hydropower plant in North Wales, UK.
GE Vernova is expected to replace two 315 Megawatt (MW) units to improve the plant’s reliability, availability and efficiency.
By the end of the decade, the two new units at Dinorwig will help ensure the continued delivery of the fast, flexible generation that plays a crucial role in supporting UK grid stability.
These three paragraphs add some more detail.
First Hydro Company (joint venture between ENGIE and La Caisse), and GE Vernova Inc. (NYSE: GEV), announce the next phase of the modernization/replanting of the Dinorwig pumped storage hydropower plant in North Wales, UK. Under the agreement, GE Vernova is expected to replace two pumped storage units as part of First Hydro’s long-term replanting programme at Dinorwig, to help extend the life of the plant for decades to come, while enhancing the plant’s reliability, availability and performance in support of UK grid stability.
Now over 40 years old, Dinorwig is Europe’s largest pumped storage hydropower plant and is renowned for its rapid response capability, delivering up to 1,320 MW of power within 12 seconds from standby, and up to 1,800 MW in under a minute. With such characteristics, this plant plays a vital role in grid resilience and frequency response, providing a capacity equivalent to power around one million homes in the UK.
As majority owner and operator of the plant through First Hydro Company, ENGIE is making a significant long-term investment to extend its operational life. The wider programme includes the replacement of key plant components across all six generating units, alongside significant infrastructure upgrades.
Note.
- According to the Wikipedia entry, Dinorwig power station has a storage capacity of around 9.1 GWh.
- It was commissioned in 1984.
- The plant was built by an Alfred McAlpine / Brand / Zschokke consortium.
As in 1984, Artemis was very busy, managing projects like this, I’d be very interested to know, if this was a project managed by Artemis.
ENGIE And CDPQ To Invest Up To £1bn In UK Pumped Storage Hydro Assets
The title of this post, is the same as a news item from ENGIE.
These four bullet points act as sub-headings.
- Refurbishment programme to extend life of plants at Dinorwig and Ffestiniog will ensure the UK’s security of supply and support the transition to a low carbon energy future
- ENGIE owns 75% of the plants via First Hydro Company, a 75:25 joint venture with Canadian investment group CDPQ
- The two pumped storage hydro plants are the UK’s leading provider of power storage and flexibility, with 2.1GW of installed capacity
- They represent 5% of the UK’s total installed power generation capacity and 74% of the UK’s pumped storage hydro capacity
These three paragraphs give more details.
The preparation of a 10-year project of refurbishment at *ENGIE’s Dinorwig pumped storage station has begun, following an 8-year refurbishment at Ffestiniog, enabling the delivery of clean energy whenever needed.
These flexible generation assets, based in North Wales, are essential to the UK Government’s accelerated target of achieving a net zero carbon power grid by 2030. Together they help keep the national electricity system balanced, offering instant system flexibility at short notice. The plants are reaching end of life and replanting will ensure clean energy can continue to flow into the next few decades.
Re-planting could see the complete refurbishment of up to all six generating units at Dinorwig – a final investment decision is still to be made on the number of units to replace – while the re-planting at Ffestiniog will be completed at the end of 2025. The program also involves the replacement of main inlet valves – with full drain down of the stations – and detailed inspections of the water shafts.
It also looks like the complete refurbishment at Dinorwig will take ten years, as it seems they want to keep as much of the capacity available as possible.
When the replanting is complete, the two power plants will be good for twenty-five years.
Hopefully, by the time Dinorwig has been replanted, some of the next generation of pumped storage hydroelectric power stations are nearing completion.
The news item says this about Dinorwig.
Dinorwig, the largest and fastest-acting pumped storage station in Europe, followed in 1984 and was regarded as one of the world’s most imaginative engineering and environmental projects.
Dinorwig must be good, if a French company uses those words about British engineering of the 1980s.
