Mikkeli city, the home of Savosolar received the “Inspiring Solution Award” in 2018 Celsius City Summit for the Ristiina Village project. It is a green district heating energy concept with a clever combination of solar thermal and wood chips.
Savosolar was involved in this award winning project by delivering turn-key solar district heating installation to the Ristiina district heating plant.
Under construction
Lübeck, Germany (largest solar thermal plant in Schleswig-Holstein federal state)
Summa Energy has been selected as general contractor to build a 9 MW solar thermal system on behalf of Stadtwerke Lübeck Energie GmbH for its district heating network, which supplies households in the Moisling city district with healthy heating. Only 788 pieces of Savo 16S large scale high performance flat plate collectors are sufficient to getting combined with an 3,000 m³ heat storage tank and produce carbon free heat for the needs of all connected consumers.
Additionally, a PV system will be built on site to generate the electricity consumed by the solar pumps, thus unburdening the local power grid.
The scope of supply includes also all the land works, the construction of a technical building and the supervision system to operate the plant in automatic mode.
Løgumkloster Fjernvarme is a district heating company which annually supplies 35,000 MWh of heat to over 1,500 customers. Heat is produced with a hybrid heating system consisting of a 3 MW pellet boiler, a 1.3 MW hybrid heatpump, a 3 MW absorption heat pump and a solar collector field of 15,300 m2. Additionally, the plant has two gas engines which are capable of producing 7.6 MW of heat and 6 MW of electricity and a 10 MW gas boiler which acts as back-up.
In 2015, Savosolar delivered a 9,700 m2 solar thermal field to Løgumkloster. The second order of 5,600 m2 was delivered and commissioned in the beginning of 2016. The complete field consists of 1030 Savo 15 SG collectors and covers about 20% of the annual thermal energy need of the district heating network. The largest part of the heat demand is covered by the pellet boiler, but Løgumkloster Fjernvarme has plans to change this in the future by extending the solar field and building a large seasonal water storage.
A new forerunner project on the large scale solar thermal market in which Savosolar has been involved: The first solar thermal field with double glasses collectors on trackers. This innovation has been done to optimize the annual solar production with a limited available area. This new solar thermal plant is a property of newHeat and will delivered heat the network of the city of Pons, which is managed by Dalkia.
Savosolar supply on this project consist in the complete solar field field as a turnkey solution, it means, the design, the supply and the installation of the solar collectors and its trackers, as well as the piping, until the solar station. It represents 112 Savo 15 DG-M collectors, which will reduce of 210 tons per year the CO2 emissions for the city’s heat needs.
