Energy will be produced by two solar panel fields, with an annual electricity output of 3,600 MWh
Lempäälän Energia has selected Siemens to build a self-sufficient smart grid system in the industrial area of Marjamäki, Finland to help safeguard electricity supply.
After implementation of the microgrid, industrial businesses in the area will be able to connect to the distributed energy system, and flexibly participate in different energy markets. If necessary, the energy system is also capable of independent off-grid operations by disconnecting from the national grid, said Siemens.
Siemens’ scope of supply encompasses design and engineering of a smart medium-voltage microgrid, corresponding grid automation system and an electrical storage system.
“Our goal is to create an energy community with decentralised generation of renewable energy,” said Toni Laakso, CEO of Lempäälän Energia Oy.
“This involves ensuring the security of supply of the energy community and ensuring its functionality at all times. Automation plays an important role in the energy community, since it ensures the system’s performance.”
The objective of the project is to create an energy self-sufficient business district. It is located in the Marjamäki industrial area in the municipality of Lempäälä, near Tampere in Finland.
The energy will be produced by two solar panel fields, with an annual electricity output of 3,600 MWh and will feature more than 15,000 panels, six gas motors and fuel cells.
In addition, the energy community production facilities use combined heat and power production to maximise efficiency. If more energy is produced than consumed, the surplus will be offered to the national electricity transmission grid operator Fingrid.
“The project uses the latest micro grid technology solutions to balance and secure energy production in the area,” added Thomas Zimmermann, CEO digital grids at Siemens Energy Management.
“The combination of advanced control, distributed grid architecture and assets in the form of microgrids will ensure the grid is operated as reliably, resiliently, and efficiently as possible.”
Siemens will implement state-of-the-art technology including the Sicam Microgrid controller, which ensure reliable monitoring and controlling as well as blackout protection. According to Siemens, it offers flexible communication, seamless continuity, maximum security, and unlimited migration, thus securing the optimal use of the generation systems.
It will also include EnergyIP DEMS, which allows aggregation of decentralised energy system to provide ancillary service for utilities or trade energy in intraday market.
The project has been chosen as one of 11 key projects concerning renewable energy and new technology awarded in 2017. As a key project, it has been granted an investment aid from the Ministry of Economic Affairs and Employment (MEAE).
The key projects focus on future energy solutions so that Finland can achieve its national targets and those laid down at EU level for 2030.
