Modern data centers needs extremely reliable and affordable power supply at all times. Traditionally, data center owners were not involved in generating their own power, though emergency diesels were a necessary nuisance that had to be handled locally.
With the Wärtsilä solution, a gas engine power plant is designed to be operated to meet an individual data center’s own needs, providing a competitive advantage in place of using local electricity supply. These generation assets can be owned and operated by an independent power producer or local utility, enabling them to sell power or backup capacity.
This solution also allows the data center operator to replace any capex related to backup power generation through regular fees for backup capacity, thus deferring the expenditures.
Thanks to the high efficiency of the gas engines, they provide power to the data center at lower price than grid electricity. In addition, switching to natural gas can significantly reduce the carbon footprint of a data center. The fast start up gas generation improves the system efficiency, reliability and lower electric network emissions by enabling integration of the renewables such as wind and solar power.
