Coal Creek and Dickinson

Scope

Michels Power, Inc. was contracted to completely reconstruct an HVDC Substation and AC to DC Converter System to increase grid reliability and reduce power loss. Michels Power scope of work included demolition of the existing thyristor valves and associated equipment, demolition of the existing air-cooled equipment, and removal of DC substation equipment. Once removed, crews assembled and installed new thyristor valves, a new liquid-cooled system for valves, control and relay upgrades, and new DC substation equipment, including bus work, DC breakers, surge arresters, reactors, DCCTs and DC Optical CTs.

Michels Power designed and built shoring for underneath the main floor in the converter stations. Given the short outage window and the tight work space, Michels Power also pre-built the new valves in a large heated tent prior to bringing them inside the building.

At the Dickinson substation, an 80-foot by 308-foot heated tent was installed to pre-build the valves. At the Coal Creek substation, a 100-foot by 350-foot pole shed was used. The pre-building of the valves took several months to complete.
