ABB, the leading power and automation technology group, has been awarded an order worth around $60 million by American Electric Power (AEP) to replace a 30-year-old HVDC back-to-back converter station in Texas. The order was booked in the second quarter.
The project scope includes engineering, supply, installation and commissioning of an HVDC back-to-back transmission system capable of delivering 220 megawatts (MW) of power in either direction. The new system will have black-start capability, which enables fast grid restoration in the event of a power outage, allowing power to be used from the other end of the link. This is an important feature as the converter station is an integral part of the Oklaunion HVDC transmission link - an asynchronous interconnection between the Texas (ERCOT) and Oklahoma (SPP) power grids.
