Finland based Lempaaian Energia has selected Siemens to develop a smart grid in the municipality of Lempäälä, near Tampere.
Toni Laakso, CEO of Lempäälän Energia Oy, said: “Our goal is to create an energy community with decentralised generation of renewable energy.
“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 smart grid system will include a smart medium-voltage microgrid, grid automation system and an electrical storage system.
The microgrid will comprise 15,000 solar panels, six gas motors and fuel cells to have an annual electricity output of 3,600MWh.
The project is funded by the Ministry of Economic Affairs and Employment, has been named LEMENE and will connect industrial consumers in Marjamaki.
The initiative will allow consumers to participate in different energy markets and will use combined heat and power production to maximise efficiency.
In case more energy is produced than consumed, Lempaaian Energia will direct surplus energy for use by the national electricity transmission grid operator Fingrid.
Siemens is responsible for the supply of infrastructure and technologies required, as well as for the design and engineering of the microgrid.
Technologies to be provided include the SICAM Microgrid Controller for remote and reliable monitoring to avoid blackouts. The solution provider claims the technology offers flexible communication, seamless continuity, maximum security and unlimited migration, thus securing the optimal use of the generation systems.
The technology will include EnergyIP DEMS, which allows aggregation of decentralised energy systems to provide ancillary service for utilities or trade energy in intraday markets.
Thomas Zimmermann, CEO digital grids at Siemens Energy Management, added: “The project uses the latest micro grid technology solutions to balance and secure energy production in the area.
“The combination of advanced control, distributed grid architecture and assets in form of microgrids will ensure the grid is operated as reliably, resiliently, and efficiently as possible.”
