Siemens will design and engineer a smart medium-voltage micro grid, corresponding grid automation system and electrical storage system. After completion, the project LEMENE will enable businesses in the Marjamäki area to connect to the distributed energy system and flexibly participate in different energy markets. The project will also be capable of independent off-grid operations by disconnecting from the national grid.
“Our goal is to create at energy community with decentralised generation of renewable energy” said Toni Laakso, CEO of Lempäälän Energia Oy. “This involves ensuring security of supply for the energy community and ensuring it functions at all times. Automation plays an important role in order to ensure the system’s performance”.
The project is located in the Marjamäki industry area in the municipality of Lempäälä, near Tampere in Finland. Energy will be generated by two solar farms with an annual electricity output of 3,600 MWh and featuring more than 15,000 panels, six gas motors and fuel cells. The facilities will also use combined heat and power (CHP) production to maximise efficiency. Any surplus energy will be offered to the national grid operator Fingrid.
Thomas Zimmermann, CEO Digital Grids at Siemens Energy Management, added that the project uses the latest microgrid technology solutions to balance and secure energy production in the area. The combination of advanced control, distributed grid architecture and assets in the form of micro grids will ensure the grid is operate as reliably, resiliently and efficiently as possible.
Siemens will implement state-of-the-art technology including a SICAM microgrid controller. This ensures reliable monitoring and control as well as blackout protection. EnergyIP DEMS allows aggregation of decentralised energy to provide ancillary services for utilities or to trade energy.
The LEMENE project was chosen as one of eleven key renewable energy and new technology projects in 2017. It was granted investment aid from the Finland Ministry of Economic Affairs and Employment (MEAE). These three projects focus on future energy solutions so that the country can achieve its national targets for 2030.
