INNIO announced that it will supply six Jenbacher natural gas engines for a wide-ranging Finnish microgrid project including solar power, energy storage and onsite gensets.
The former distributed energy unit of GE, separated only four months ago, gained the contract to supply the LEMENE microgrid. The new project and combined heat and power plant will service a business district and provide backup support for renewable energies.
“The LEMENE project is key to helping the Finnish government reach its national energy decarbonization goals and to make the Marjamäki industrial district energy self-sustaining,” ,” said Toni Laakso, CEO, Lempäälän Energia Ltd. “We chose Jenbacher gas engines because of INNIO’s long-standing experience with gas engines, especially with burning greener gases such as biomethane. These six gas engines will provide the district with reliable, efficient and economically friendly power and heating
Located in the Marjamäki industrial area in the Lempäälä municipality, the LEMENE microgrid project will have a variable renewable energy source as twin 2-MW solar power plants. The six gas engines, with a total capacity of 8.1 MW, are the key elements providing secure energy as the solar power production varies.
The microgrid also comprises a fuel cell solution—providing a total of 130 kW—and a battery to even out temporary fluctuations in energy production. INNIO’s three Jenbacher J416 and three Jenbacher J420 CHP units will run on natural gas or biomethane as available to make the gas engine a CHP carbon-neutral solution.
The entire system is expected to be commissioned by the summer of 2019.
By using INNIO’s Jenbacher gas engine CHP system, the LEMENE project plans to avoid 235 kilograms of carbon dioxide (CO2) emissions per MWh of electricity produced compared to electricity-only operation and heat provided by a natural gas boiler. The result is a reduction of 7,629 tons annually of CO2 if all six engines run a total of 4,000 operating hours per heating season.
INNIO was separated out of GE when investors Advent International acquired the Jenbacher and Waukesha engine lines last year. The carve-out was completed and rebranded as INNIO four months ago.
The company is headquartered in Tyrol, in western Austria.
