ABB commissioned a power solution that will control the flow of power and enhance grid stability in the State of Michigan. ABB’s low-loss and eco-efficient HVDC Light technology controls the power flow between the upper and lower peninsulas of Michigan. The HVDC Light station was commissioned on schedule and handed over to the customer, American Transmission Co. (ATC). ABB designed, supplied and installed the 200-MW back-to-back HVDC Light station in upper Michigan. An HVDC back-to-back system comprises two HVDC converters connected directly to each other, without any DC transmission line, making it possible to control the power transfer through the connection.
