8 billion barrels (abt 1.1 billion metric tons) of oil. Gas is imported through the West of Shetland pipeline. Some of the gas is used as fuel in the ENGIE operated Sullom Voe power station. The remainder is enriched with LPGs and exported to the Magnus platform for enhanced oil recovery. Due to its secluded position, the site has its own fire brigade. On 3 May 2018 it was reported that both the Brent and Ninian pipelines had to be shut down - halting production from the connecting fields in the East of Shetland basin. The pipelines were shut down due to a "minor fault" being found during a routine inspection. The minor fault was reportedly a small oily-water leak in a pipeline. Late on 6 May, EnQuest announced repair work had been completed and both the Brent and Ninian pipelines were reopened. On 25 November 2018 the Sullom Voe Terminal reached a milestone 40th anniversary since first oil. Throughput The throughput of the terminal over the period 1981 to 1990 (in 1000 barrels per day) was: The total throughput of the terminal up to the end of 1997 was 821,773,000 tonnes. The throughput over the period 1998 to 2021 (in 1,000 tonnes) was: Sullom Voe power station The gas turbine power station provides electricity for around 43% of the Shetland Islands (since the early 1990s) and the other half comes from the (fuel oil-powered) Lerwick Power Station situated at Gremista. Shetland requires about 50 MWe in the winter. From May 2004 to May 2014 it was operated by the Finnish company Fortum; previous to that it was operated by BP. Since May 2014 it has been operated by Cofely Limited, a GDF SUEZ company. The 100 MWe plant has four 25 MW General Electric Frame 5 gas turbines and is part of a CHP system being built in the late 1970s. The actual power output from the plant is around 80 MWe as each turbine runs at about 18 MW. When the oil terminal was at the height of its production, 70 MWe would be used from five gas turbines by the plant, but less is needed now. It employs around twenty people. Shetland Gas Plant Sullom Voe is directly neighboured by the TotalEnergies operated gas facility Shetland Gas Plant, completed in 2014.
