ScottishPower Renewables partners with Pfisterer for East Anglia ONE wind farm

In cooperation with British cable manufacturer JDR, Pfisterer has received the order for the delivery of CONNEX cast resin joints and CONNEX plug connectors for up to 72.5 kV for the networking of the new East Anglia ONE (EA1) wind farm.

In the initial phase, the new wind farm includes the construction of 102 Siemens turbines with total output of 714 megawatts. Because of the high output level, the networking will take place with 66 kV. Pfisterer is the only manufacturer with a solution that has proven itself for 20 years in the offshore area.

The new East Anglia ONE wind farm of operator ScottishPower Renewables is being constructed 43 km from the coast of Suffolk in the southern North Sea, and is in the axis between Amsterdam and London. With total output of 714 megawatts, it will be capable of supplying about 500,000 households when it reaches its planned completion in 2020. 102 Siemens turbines, each with 7 MW, will be set up from the middle of next year, and will be connected via two converter stations in a 66 kV network. East Anglia ONE is the first large scale wind farm to be set up with this voltage level. “Because the efficiency and output of wind turbines are constantly on the increase, wind farms all over the world are changing from the previous 33 kV networks to 66 kV networks”, explains Peter Müller, Senior Manager Sales at Pfisterer. “We have already had a suitable connection for this output range for connecting the inter-array cables to the turbines for 20 years with the size 4 Connex cast resin joint and the Connex plug connector. The inner cone technology is ideal for this level of capacity, which is why we are receiving many inquiries at present”.
