TIGON project launched!


We’re happy to announce the start of a new project in which we are involved in as a partner. The project TIGON is set to demonstrate how direct current (DC) microgrids can help make the EU's electricity grids greener, more efficient, and more resilient as the world turns to renewable energy.

Most grid infrastructure is based on alternating current (AC) However, most popular renewable energy sources generate DC output, either directly or through a power converter. As they are intermittent, their power must be stored in batteries – again in DC. Furthermore, most modern electrical equipment such as laptops, mobile phones and LED lighting operate on DC. The question then arises: how do we draw on the legacy of the AC grid infrastructure when generation and consumption are increasingly DC?

TIGON aims to make a business case for advanced hybrid microgrids. The project will develop and demonstrate flexible solutions in two microgrids in France and Spain. The demonstrations will integrate solar power, energy storage systems, electric vehicle charging points and other DC loads using highly efficient grid technologies such as solid-state transformers, DC/DC converters and energy management systems.

The replication potential of the demonstrations will be tested in two use cases, the other one being the DC microgrid at Naantali Luonnonmaa residential district near Turku. Our role in the project is to lead the the analysis and provide results and conclusions on TIGON replication potential in Finnish infrastructure and legislation, and on the benefits of extending the DC network and improving its interaction with the main grid. Some of the solutions developed in TIGON are intended to be used in the DC microgrid currently being developed in one of our other project, SLEPS.

The international project consortium of TIGON is led by CIRCE (Fundación CIRCE Centro de Investigación de Recursos y Consumos Energéticos) from Spain. The four-year project is funded by European Union’s Horizon 2020 research and innovation programme. 




We made a move!


With great joy, we are announcing the good news. We have moved!

A brand new EduCity campus building in Kupittaa has recently opened its doors. All our laboratory equipment has been moved to the modern and spacious premises of the new campus. The new address of our laboratory is Joukahaisenkatu 7, Turku or simply EduCity, and our facilities are found at the bottom floor. Our team has also retrieved a new office space in the adjacent ICT-City building, at room C 5093, found in the 5th floor, wing C.

The new EduCity building is equipped with many comfortable rooms and spaces. Students are treated with modern learning facilities and working spaces and there are also rooms for meetings. Cozy and stylish armchairs, big windows and open terraces provide opportunities for relaxation, and an indoor spiral slide some excitement! Sustainable development, including energy and material efficiency have guided the design. There are solar panels on the roof, good thermal insulation, and the sedum roofing of the terraces absorb and store carbon.

The new facilities are convenient to reach for both locals and visitors. Buildings are within a 200 m walking distance from the Kupittaa Railway Station and local bus lines 32 and 42 have a stop very near. If you are arriving by car, there are some paid parking spaces available. We couldn’t be more excited about the brand-new facilities and look forward to making them our home!
