Stanlow Refinery is an oil refinery owned by Essar Energy in Ellesmere Port, North West England. It was previously owned by Royal Dutch Shell until 2011. The refinery is situated on the south bank of the Manchester Ship Canal, which is used to transport seaborne oil for refining and chemicals for Essar and Shell.
Stanlow has a refining capacity of 12 million tonnes per year with a barrel per day capacity of 296,000. Consequently it is the second largest in the United Kingdom after Fawley Refinery, and produces a sixth of the UK's petrol needs. Stanlow is also a large producer for commodities such as aircraft fuel, bitumen and kerosene.
Although situated in North West England, the refinery serves much of England as it is linked to Coryton Refinery in Essex through the UK oil pipeline network. Oil is delivered to Stanlow via ship where it is then refined and stored at Eastham Oil Terminal and Tranmere Oil Terminal which are situated nearby.
The refinery occupies nearly 1,900 acres (7.7 km2) near the River Mersey and dates back to 1924, when a small bitumen plant was established. Stanlow and Thornton railway station was opened in 1940 to give workers access to the site and the facility an extra mode of transport. However, this station is now only served by three trains daily towards each of Ellesmere Port (westbound) and Helsby (eastbound), with these services scheduled to depart at times which would be inconvenient for the workers.
Crude oil is now received lower down river on the Mersey at the Tranmere Oil Terminal, operated by the Mersey Docks and Harbour Company from its Liverpool headquarters, and is transferred via a fifteen-mile (24 km) pipeline to storage at Stanlow. Output is delivered via various means, including by pipeline via the UK oil pipeline network, road and the Manchester Ship Canal.
In 2010, Royal Dutch Shell declared their desire to sell off their refineries in Europe to concentrate on emerging markets in Asia and the Middle East, which led to the possibility that Stanlow would be shut down indefinitely. However, Shell said that a number of refineries in their portfolio offered over-capacity and consequently Stanlow, their last British refinery, was put up for sale.
After a prolonged period of negotiation, Stanlow was sold by Shell to Essar Energy for approximately $1.3 billion (£814 million) in 2011. Essar has stated their desire to expand the site with a 25% increase in output. Following the bankruptcy of Petroplus which ran the Coryton Refinery in January 2012, Essar stated their belief that Stanlow, being a large refinery, would be able to compete with refineries in Asia and the Middle East. Essar plan a £250 million expansion of Stanlow, with production of diesel and aviation fuel to be increased.
Stanlow's position as one of the largest and well-known refineries in the country, has led to numerous protests over a number of decades. In the UK fuel crisis of 2000, protests over government taxation on fuel began at Stanlow. A large fuel price protest was staged in May 2011 with the objective of "shutting down" the refinery.
