 Siemens to Provide Electrical Equipment for Michigan Combined-Cycle Plant

Siemens has been chosen to supply critical low- and medium-voltage electrical equipment and power transformers for the Holland Energy Park combined-cycle power plant in Holland, Michigan.
The company will install its SPPA-T3000 Distributed Control System technology, a software system that connects, controls and allows for communication of hardware throughout the plant, integrated with a medium- and low-voltage motor control center for centralized monitoring and operation of the electrical system. Siemens will also provide 63kA type medium-voltage GM-SG-AR switchgear including a vacuum circuit breaker 3AH3, designed to improve power reliability and increase worker safety via arc-resistant features. The company will also provide three 138-13.8kV generator step-up transformers to the plant.
Last year Siemens was chosen to provide two SGT-800 gas turbines and one SST-400 steam turbine for the plant, which the municipal utility Holland Board of Public Works is using to replace an older, coal-fired power plant that was less efficient. The new facility is due to begin commercial operation this year. The cogeneration functionality of the plant will make it a highly efficient installation, providing about 125 MW in summer and 145 MW in winter. Additionally, the plant will use surplus heat from the circulating water system to expand a downtown snow melt system.
