Last Energy unveils £300m micro-modular nuclear power plant scheme in Wales

Last Energy, a pioneering US-based start-up, has unveiled plans to develop a series of micro-modular nuclear power plants in South Wales, representing a substantial investment in the UK’s nuclear energy sector. The £300 million ($366 million) project will see the construction of four 20 MWe micro-modular nuclear units, delivering a total capacity of 80 MWe, enough to power approximately 244,000 UK homes annually.

The micro-modular nuclear plants will be located in Bridgend County, on the former site of the Llynfi Power Station. This ambitious project marks a significant step towards a clean energy future, with the first of the plants scheduled for completion by 2027, subject to licensing and planning approvals. Last Energy’s innovative approach to nuclear power will introduce a new era of energy generation to the UK, offering a sustainable and reliable alternative to fossil fuels.

The project is set to deliver a considerable boost to the local economy. Approximately 100 full-time jobs will be created for the community in Bridgend, while at least 10% of the project’s procurement needs will be sourced from South Wales suppliers. This local investment will inject around £30 million into the regional economy, supporting local businesses and fostering economic growth in the area.

Last Energy’s micro-modular nuclear plants, known as PWR-20, feature an advanced modular design, enabling rapid deployment and scalability. The plants will be assembled using modular components, which can be fabricated, transported, and assembled on-site within 24 months, much like constructing a “LEGO kit.” This innovative approach to nuclear plant design ensures faster construction times and reduces overall costs, making the project economically viable through pure private financing without the need for public funding.

The development of these micro-modular nuclear units is strategically important for both the UK and Wales. The project supports the decarbonisation of industry by providing clean, reliable power to mid-size manufacturers in the region. It also aligns with the UK government’s broader strategy to expand nuclear capacity and achieve long-term energy security. Additionally, it contributes to the Welsh Government’s 2030 net-zero targets and the UK’s wider climate goals.

The UK government has welcomed Last Energy’s investment, recognising its potential to drive the growth of the nuclear power sector, create skilled jobs, and support the country’s decarbonisation efforts. As nuclear energy plays a critical role in the UK’s energy transition, projects like this represent a vital step towards ensuring energy security and a sustainable future.
