LEMENE - Solarigo reference story

SELF-SUFFICIENCY

The LEMENE Project

Solarigo participated in the LEMENE energy technology flagship project led by Lempäälän Energia, in the role of a solar power plant supplier. Solarigo delivered a 2,000 kWp ground-installed solar power plant for the LEMENE energy community in 2019. When completed, the solar power plant was one of the largest in Finland. The 2,000 kWp solar power plant delivered by Solarigo covered half of the project's 4,000 kWp total solar energy

Solar energy as part of an energy self-contained community

The LEMENE project (Lempäälä energy community) is a flagship project of the Finnish Ministry of Economic Affairs and Employment, which was completed in 2019. A self-contained smart energy system was implemented in the Marjamäki industrial area near the Ideapark shopping centre. In this new operating model, operators in the industrial area can join a decentralised energy system, where energy is produced with solar panels, gas engines and fuel cells.

A FLAGSHIP PROJECT IN ENERGY TECHNOLOGY REQUIRES A VISION

The basic idea of the Lempäälä energy community has been to build an intelligent and self-contained energy microgrid, which will secure the energy supply for the entire community self-sufficiently. The system's energy production is generated by gas engines, solar power plants and fuel cells. In addition to the production units, the energy system includes electric batteries, a thermal battery, a heat pump and five substations, which are interconnected in their own local medium voltage network.

Solar power was chosen for the project because it works well alongside gas-based CHP production, supplementing the energy balance during summer days. Two solar power plant suppliers were sought for the project, both with a size of 2,000 kWp.

Solarigo was chosen due to its capacity for large-scale implementations. At the same time, Solarigo had other on-going projects on the MW scale. The installation of the solar power plant was carried out professionally and on schedule:

"Solarigo was involved in planning the project implementation from the very beginning and had already brought a great deal of its own know-how to the project at this stage. During the project, Solarigo's project manager was active and handled the tasks and communication in an exemplary manner," notes Jarno Lintunen, CEO of Lempäälä Energia.

The production of the solar panel field has met our expectations. In the LEMENE environment, with the help of the batteries of the hybrid system, it is possible to equalise the fluctuation of solar energy production, for example when the weather changes from the forecast. The project has sparked a great deal of discussion about the development of the energy sector in general, as well as from the perspective of utilising technology. Lempäälä municipality's high priorities are being pioneers in the energy sector, and meeting its HINKU goals. With the help of solar power, the municipality and the LEMENE project have received a considerable amount of positive attention.

Solarigo is a capable, reliable, open and responsive partner. Doing business with Solarigo has always been smooth and expertise has always been available very quickly when needed.
