Led by Finland-based energy company Lempäälän Energia, the grid is one of the key projects designated by the government to help the country reach its national energy targets for de-carbonisation.
Lempäälä Energia CEO Toni Laakso said: “The Lemene system will operate mainly as part of the public electrical grid but can also operate as a supporting reserve system for the public electrical grid, or independently off-grid, on demand.
“The LEMENE smart grid will feature a variety of smart technologies that will respond to changing electric demand, enabled by automation solutions adapted to the micro-grid. An important part of the project is to secure energy availability as renewable energy production varies.
“In conjunction with the solar array and battery storage, the Lemene system also required a highly-efficient CHP system from Convion that would convert biogas to generate electricity and heat to supply nearby businesses.”
The new smart grid will feature a 4MW solar photovoltaic (PV) array, an 8MW biogas engine and a battery to offer secure and reliable power to around 50 businesses in the industrial district of Marjamäki, south-western Finland.
Under the agreement, Convion will build the two fuel cell co-generation systems and integrate them into the district’s smart grid.
The CHP systems will be equipped with Elcogen’s next generation of solid oxide fuel cell (SOFC) stacks and will have the capacity to generate 116kW electrical output.
According to the Finnish Ministry of Economic Affairs and Employment (MEAE), the Lemene system has the potential to help Finland achieve its national targets and those set by the EU for 2030.
