Police escort for supply of huge ‘shunt reactor’ to Crystal Rig

The construction of the onshore work to support the Neart na Gaoithe (NnG) offshore wind farm is due to be completed over the weekend with the delivery of a massive “shunt reactor” to the site of the connection of the wind farm to the National Grid in Lammermuir Hill.

The 160-ton shunt reactor (10 meters long, 3 meters wide, 5 meters high) regulates the voltage and compensates for the length of the onshore and offshore cables, which use up to 450 megawatts of green electricity from the NnG wind farm in the outside Forth Estuary to its onshore substation in the existing Crystal Rig onshore wind farm.

The substation is due to be completed next year and is an integral part of the wind farm being developed by EDF Renewables (UK) and ESB.

The shunt reactor was transported from the port of Leith on a special 67 m long trailer overnight from Friday to Saturday to the NnG onshore substation near Innerwick, accompanied by the police. It was then reloaded onto a 45 m long trailer that could negotiate the narrower road to the Crystal Rig.

Matt Hagg, Project Leader, said, “The shunt reactor is critical to enable NnG to be securely connected to the National Grid. We would like to thank all of our neighbors in Innerwick and the surrounding area for their patience during the safe passage to the substation. ”

A second shunt reactor is to be delivered next weekend.
