Vattenfall inaugurates 228MW onshore wind farm in Wales

CTBR Staff Writer Published 29 September 2017

Vattenfall has inaugurated the 228MW Pen y Cymoedd in south Wales, the UK.

Claimed to its largest onshore wind farm, it can produce enough clean electricity for  188,000 households in the UK.

The wind farm features 76 turbines, each with a capacity to produce 3MW and will be supported by a co-located battery facility to store the electricity that is generated.

Pen y Cymoedd  wind farm is expected to help remove  about 300,000 tonnes of CO2, had the electricity been generated using fossil fuel-fired generators.

The company also claimed that Pen y Cymoedd will be the largest commercial wind farm in the world with a co-located battery facility for storing electricity.

Vattenfall´s Wind Business head Gunnar Groebler said: “We want to continue growing in the renewable sector to become fossil-free within a generation. With Pen y Cymoedd, and the possibility to store energy, we continue to transform our energy production and find new and innovative ways to help customers and partners to be climate smart.

“Completing our so far largest onshore wind farm successfully underlines that we are well on track with our ambitious goals in wind power.”

In the coming months, Vattenfall will start installing battery energy storage facility to support grid integration and the  batteries will be supplied by BMW Group.

Vattenfall and BMW have signed a supply agreement in March this year. For the storage facility it will supply 1,000 of its lithium-ion batteries, each with 33kWh of capacity.

Vattenfall president and CEO, Magnus Hall, said: “Pen y Cymoedd boosts Wales’ drive to carbon reduction, it accelerates Vattenfall’s shift to be fossil free in a generation and it helps the Welsh economy to grow.

“Vattenfall and our contractors have spent £220m in the Welsh economy since construction started in 2014, which is 52 per cent of the total investment we have made in Pen y Cymoedd.”

Pen y Cymoedd wind farm was built by a 50:50 joint venture of Jones Bros and Balfour Beatty for Vattenfall.

The inauguration ceremony was attended by Wales First Minister Carwyn Jones. He said: “Wind power is a key part of our efforts to build a sustainable low carbon economy for Wales. I am pleased we were able to support this project, which has shown how the local community, the Welsh economy and people right across the country can benefit from such a scheme.”
