Under the contract, ABB will provide two new substations and key equipment including compact 132kV PASS (Plug and Switch System) hybrid switchgear and STATCOM (Voltage Source Converter based reactive power compensation) units for the Pen y Cymoedd wind energy project.

The scope of the contract also includes providing transformers to step up the voltage from 33kV at the generation point to 132kV for sub-transmission and then to 400kV for input into the National Electricity Transmission System.

The two new substations linked by 9.2km of underground cable will be equipped with IEC 61850 compliant substation automation, control and protection equipment.

ABB Substations business head Oleg Aleinikov said, "The substations will help the grid connection of wind energy, enhancing power supplies to meet growing demand for electricity."

"They will also reinforce the transmission grid and help enhance reliability and efficiency," added Aleinikov.
