ABB has secured a contract from Vattenfall to provide a grid connection and the associated power infrastructure for the Pen y Cymoedd wind energy project in Wales, the UK.
Under the contract, ABB will design and construct two new substations, which will be equipped with IEC 61850 compliant substation automation, control and protection equipment and linked by 9.2km of underground cable.
ABB will supply key equipment including compact 132kV PASS (Plug And Switch System) hybrid switchgear and STATCOM (Voltage Source Converter based reactive power compensation) units to enhance grid voltage stability.
The contract will also see ABB supplying 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.
ABB Substations business head Oleg Aleinikov said the substations will help to integrate wind energy and increase power supplies to meet growing demand for electricity as well as reinforce the transmission grid and help enhance reliability and efficiency.
The project, which is to be built on publicly-owned land managed by the Forestry Commission Wales, will feature 76 Siemens turbines totalling up to 228MW, which is enough electricity to power 140,000 homes.
In July 2013, Siemens was awarded a contract to supply turbines for the project as well as provide maintenance services for five years following its commissioning.
Scheduled to be operational by 2016, the project, located between Neath and Aberdare in South Wales, is claimed to be the largest onshore project in England and Wales.
In October 2013, a joint venture partnership between Jones Bros Civil Engineering UK and the Wales Division of Balfour Beatty Construction Services UK has been awarded a contract to provide civil and electrical infrastructure for the project.
Vattenfall had received development consent from the Department of Energy and Climate Change for the project in May 2012.
The project, which expects to generate its first power in 2016 and become fully operational in spring 2017, is estimated to cost around £300m (€353.2m) and inject £1bn (€1.17bn) into the Welsh economy over its 25- year life span.

Press Release:ABB, the leading power and automation technology group, has won an order to provide a grid connection and the associated power infrastructure for Vattenfall’s Pen y Cymoedd Wind Energy Project, being developed in Wales, United Kingdom. The 76-turbine, 228 megawatts (MW) wind farm being developed in South Wales, will be the largest onshore wind farm in England and Wales and one of the largest in Europe. It is scheduled to be operational by 2016.
The UK has a total installed capacity of more than 10,000 megawatts and is ranked among the world’s six largest producers of wind power. It is considered to be the best location for wind power in Europe and among the finest in the world, with over 6,300 MW of the capacity located onshore and the rest offshore.
As part of the project scope, ABB will design and construct two new substations linked by 9.2 kilometres of underground cable. Key equipment supplies include compact 132 kilovolt (kV) PASS (Plug And Switch System) hybrid switchgear and STATCOM (Voltage Source Converter based reactive power compensation) units to support grid voltage stability.
ABB will also supply transformers to step up the voltage from 33 kV at the point of generation to 132 kV for sub-transmission and then to 400 kV for input into the National Electricity Transmission System. The substations will also be equipped with IEC 61850 compliant substation automation, control and protection equipment.
"These substations will help to integrate wind energy and boost power supplies to meet growing demand for electricity" said Oleg Aleinikov, head of ABB’s Substations business, a part of the company’s Power Systems division. "They will also reinforce the transmission grid and help enhance reliability and efficiency."
ABB provides a wide range of products, systems and services that enable the efficient generation and integration of renewable wind energy into the grid and its reliable transmission and distribution.
Substations are key installations in the power grid that transform voltage levels and facilitate the safe and efficient transmission and distribution of electricity. They include equipment that protects and controls the flow of electric power. ABB is the world’s leading supplier of turnkey air-insulated, gas-insulated and hybrid substations with voltage levels up to 1,100 kV.
