독일의 다국적 대기업인 Siemens가 Holland 시에 지어질 Holland 에너지 공원의 복합사이클 전력 플랜트에 두 개의 가스터빈과 한 개의 증기터빈을 공급하고 있다고 발표했다. 지자체 시설인 Holland 공공사업 이사회는 기존의 화력발전소를 신 저연비 현대화 전력 플랜트로 교체하고 있다. 새 플랜트는 여름에 약 125MW, 겨울에 약 145MW의 전력을 생산할 것으로 기대된다.

새로운 시멘스 기술로 이 지역에서의 이산화탄소 배출량은 약 50% 저감될 것으로 보인다.

 

 

 

Siemens, a German multinational conglomerate company, has announced that it is supplying two gas turbines and one steam turbine for the Holland Energy Park combined-cycle power plant, to be constructed in the city of Holland, Mich. The local municipal utility, Holland Board of Public Works, is replacing a coal-fired plant with the new fuel-efficient modern power plant, which will generate approximately 125 megawatts in the summer and 145 in the winter.

 

With the new Siemens technology, the CO2 emissions at the site will be reduced by approximately 50 percent. A special feature of the plant is the use of surplus heat from the circulating water system for use in expanding a downtown snowmelt system. Siemens' scope of supply includes two SGT-800 gas turbines and one SST-400 steam turbine. The company will also provide a long-term service contract for the SGT-800 turbines. The new plant's co-generation capabilities provide it with an extremely high fuel-efficiency level.

 

Holland maintains the largest municipally-owned snowmelt system in the nation; the underground pipe system spans roughly 46,000 square meters of city roads and sidewalks. In the cold weather months from October until April, Michigan has about 32 days of average total snowfall, with up to 177 centimeters per year. Circulating water from the new facility will be run through a heat exchanger to warm water for the snowmelt system in the downtown area. This, in turn, alleviates the need to salt or plow during the winter months. The system can melt approximately 2.5 centimeters of snow per hour in temperatures of -9 to -7 degrees Celsius.

 

"This new combined-cycle plant makes a two-fold contribution to environmental protection," said Wolfgang Konrad, head of the Distributed Generation business unit within the Siemens Power and Gas Division. "On the one hand, it replaces a coal-fired plant, which halves the CO2 emissions, and, on the other, it helps do away with the need for salt and grit in the winter." Commercial operation of the plant is scheduled for fall 2016.
