A microgrid demonstrator has started operations in Singapore through a collaboration between French energy companies EDF and Enedis and the Nanyang Technological University (NTU).
The Masera – for Microgrid for Affordable and Sustainable Electricity in Remote Areas – microgrid project is part of the Singapore International Energy Week and the 2018 France-Singapore Year of Innovation. This demonstrator will allow EDF to deploy a commercial offer of affordable and high-performance microgrids for isolated territories in south-east Asia.
EDF’s Masera is part of NTU’s offshore microgrid testbed known as Reids (Renewable Energy Integration Demonstrator – Singapore). Located at Semakau landfill, Reids is the region’s first offshore microgrid testbed that integrates multiple renewable energy sources to develop ways to tackle regional electricity problems.
On this platform, EDF, at the head of a consortium of French smart grids and smart cities companies, has designed, built and commissioned the Masera demonstrator within one year, a record time for such a prototype, integrating various innovations:

  • 50kW of bifacial photovoltaic panels;
  • Lithium-ion storage system provided by Socomec;
  • Eco-friendly zinc-air battery from EDF spin-off Zinium;
  • Nissan Leaf electric vehicle;
  • V2G (vehicle to grid) software platform and bidirectional charging hardware from Nuvve;
  • Load bank to reproduce typical customers’ consumption;
  • EDF local and remote microgrid control system allowing standardised communications and generation optimisation; and
  • Reliable and secure smart meter infrastructure with the expertise of Enedis.
In Singapore, EDF relied on the experience of local companies such as Aurecon for the detailed technical design and Caxton for the construction of the demonstrator.
The industrial, innovative and easily deployable project should allow EDF to support economic development in south-east Asia and therefore improve the quality of life of communities.
This project illustrates EDF’s expertise in designing, developing and executing smart grid and microgrid projects on islands and territories with no access to the grid or facing reliability issues. In recent years, EDF has developed multiple innovative microgrids, including a 100 per cent renewable energy system on La Réunion island, the Nice Grid demonstrator in Carros near Nice and hybrid microgrids in Toucan and Kaw in French Guiana. In these developments, EDF benefits from Concept Grid, the EDF R&D smart grid laboratory near Paris.
Microgrids leveraging the potential of renewable energies offer development perspectives in south-east Asia, taking into account the geographies, the current lack of infrastructures and the economic growth of the major countries in the region.
“I am happy to be celebrating the launch of the Masera demonstrator,” said Bernard Salha, senior executive vice president of EDF Group. “This project allows us to combine the expertise and knowledge of Enedis, of the Nanyang Technological University of Singapore, of companies from the French Think Smartgrids association, which federates the whole players of the smart grid ecosystem like Enedis, Socomec, Sagemcom and start-ups, and of the EDF Group in the domain of microgrids. Thanks to Masera, EDF, whose ambition is to become one of the world leaders in microgrids, will improve its knowledge of local markets, reinforce its R&D and demonstrate the reliability of off-grid and microgrids which can be developed in south-east Asia, which is at the heart of the group’s international strategy: renewable generation, energy efficiency, smart city.”
Marianne Laigneau, EDF group senior executive vice president, added: “The inauguration of Masera illustrates both the technological know-how of EDF, its ability to match the specific demands of its customers and its willingness to develop its footprint in Asia which is at the heart of its international strategy.”
