Milford Haven is the UK’s largest energy port, capable of delivering 30% of the UK gas demand. Starting in 1960 when Esso completed work on the first oil refinery on the Milford Haven Waterway, the advantages of its location and deep water soon saw other oil refineries emerge on our shores. Many of the local residents who had been involved in the fishing industry retrained and learned new skills to be able to work in the energy industry.

2009 saw the first Liquified Natural Gas (LNG) ship, Tembek, berth at the South Hook LNG terminal. Along with Dragon LNG further up towards Waterston, Valero Pembroke Refinery, Valero Pembrokeshire Oil Terminal, Puma Energy and RWE’s Pembroke Power Station, Milford Haven really is a port of national significance. The infrastructure and fleets of tankers, tugs and pilot boats that move in our energy kingdom day in, day out, have a wide-reaching impact on the UK’s energy demands.

As well as the traditional energy industries, the future is looking bright in terms of the marine renewable energy which is developing off our coastline. With technology developers and supply chain businesses all working together with Marine Energy Wales to establish Wales as global leader in sustainable marine energy generation, making a significant contribution to a low carbon economy.

We’re even at the forefront of the future of the way we will fuel our cars in the future, with a new hydrogen car refueller on Mackerel Quay.

To follow the Energy Kingdom trail, keep an eye out for the yellow lamppost banners which go across Mackerel Quay. There are small signs on the same lampposts with QR codes, which will take you to the full stories created by the talented pupils from Milford Haven School as part of Milford Youth Matters’ project, funded by the Heritage Lottery Fund.
