Siemens Corp. said Feb. 24 that it is supplying two gas turbines and one steam turbine for the new Holland Energy Park combined cycle power plant in Holland, Michigan.
Holland Board of Public Works (HBPW), a municipal utility, is replacing an aging coal-fired plant with a new fuel-efficient power plant, slated for commercial operation in fall 2016. With the new Siemens technology, the CO2 emissions at the site will be reduced by approximately 50%.
Siemens’ scope of supply includes two SGT-800 gas turbines and one SST-400 steam turbine. Siemens will also provide a long-term service contract for the SGT-800 gas turbines. The new plant’s cogeneration capabilities provide it with an extremely high fuel efficiency level and will generate approximately 125 MW in summer and 145 MW in winter.
A special feature of this plant is the use of surplus heat from the circulating water system for use in expanding a downtown snowmelt system. The City of Holland maintains the largest municipally-owned snowmelt system in the United States. The underground pipe system spans roughly 11.5 acres (500,000 square feet) of city roads and sidewalks. Circulating water from the Holland Energy Park plant will 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.
“Siemens is pleased to be the technology partner for this forward-leaning energy project, which provides sustainable power while also bolstering the city’s innovative snowmelt system. As we continue to see a shift toward distributed power, Holland Energy Park will serve as a model for how a community can collaboratively work to address its power generation needs,” said Barry Nicholls, U.S. lead for Siemens Power and Gas division.
“The City of Holland is a leader in researching and implementing new ways to save and reduce energy consumption. Its cooperation with Siemens is a good example of this. Siemens supports the sustainable strategy of implementing reliable, world-class technologies to build our Holland Energy Park. We plan to make the plant accessible to the public at large to foster further interest in the city’s goal of implementing a socially, economically and environmentally responsible solution for supplying power into the 21st century,” stated Daniel Nally, Business Service Director of HBPW.
HBPW and the Holland City Council announced Jan. 21 that they have approved an Engineering, Procurement and Construction (EPC) contract with Southfield, Michigan-based Barton Malow for the design and construction of the Holland Energy Park. HBPW and Barton Malow entered into an engineering services agreement (ESA) in November 2014 to begin preliminary engineering for the plant and develop final language on the EPC contract.
“The last couple months have been invaluable in helping us reach a contract that’s favorable for all parties,” said Dave Koster, general manager at HBPW. “We have great confidence in the Barton Malow team, and we’re eager to see the Holland Energy Park take shape.”
While the approved bid was for nearly $145 million, HBPW anticipates that adjustments during the open book period of the contract will land the final price below their original budget of $140 million. However, the board still recommended approval of $145 million for contingency purposes.
With construction set to begin in February, the contract schedule calls for generation and testing in late 2016, and substantial completion by February 2017.
The Holland Board of Public Works (HBPW) is a community-owned enterprise providing electric generation and distribution, water, wastewater treatment and broadband utility services to nearly 28,000 business and residential customers in the Holland area.
