The converter station houses a 150MW back-to-back high voltage direct current (HVDC) link which facilitates the exchange of energy between several North American electricity networks.
The new contract covers the replacement of the now obsolete control equipment with the latest Alstom Grid Series V digital control system which will improve the performance and extend the life of the converter station.
The McNeill converter station, owned and operated by ATCO, is dispatched by the Alberta Electric System Operator as part of the overall Alberta Interconnected Electric System.
It is the northern-most link between the Western Electricity Coordinating Council system and the Midwest Reliability Organization.
