"This is the rebirth of Pembrokeshire. I only wish the men who were discharged from Pembroke Dockyard during the dark, depressing days were here today to see it taking place."

Desmond Donnelly, MP for Pembrokeshire, breaking ground at the new
Pembroke Refinery site in 1963

Pembroke Refinery History


Pembroke Refinery has been making products from crude oil since the early 1960s. Construction began in 1963, with production beginning in 1964 when the refinery was officially opened by HM Queen Elizabeth the Queen Mother.


The original refinery was built at a cost of £30 million with a production capacity of 100,000 barrels per day (bpd). Since then major changes have been made, making Valero Pembroke Refinery one of the most complex refineries in Europe. Sited alongside the boundary of the Pembrokeshire Coast National Park on the south bank of the Milford Haven Waterway, the  refinery occupies 550 acres of a 1,275 acre site that is landscaped to disturb as little of the natural beauty of the surrounding coastline and countryside as possible and enhance local biodiversity.


Total throughput today stands at 270,000 bpd with exports from the refinery being distributed across the UK and the world. The refinery produces around 3.6 million gallons of petrol and 2.2 million gallons of diesel per day, in addition to 16 other different products, making Pembroke one of the largest fuel manufacturers in North West Europe.


With over 1,400 jobs directly supported by Valero, Pembroke Refinery is one of the largest employers in West Wales, as well as being at the heart of Pembrokeshire’s energy sector as a member of the Haven Waterway Enterprise Zone. Approximately over £75 million per year is contributed to the local economy by the refinery, meaning the importance of Valero to the West Wales economy has never been more important.


To make Pembroke Refinery competitive for the next 50 years and secure the prosperity of our workforce, our communities and our local economy, we need to plan now for the future.
