To support the social-economic development in South East Asia (SEA) and the expansion of microgrids, in particular in remote areas, the Nanyang Technological University has created the Renewable Energy Integration Demonstrator Singapore (REIDS) project. Supported by the Singapore Economic Development Board (EDB) and the National Environment Agency (NEA), it will be the largest hybrid microgrid testbed and research platform in the tropics.

Located on Semakau island (8km South of Singapore), the infrastructure offers REIDS partners (including EDF) the possibility to integrate and promote microgrid solutions with the objectives of resilience, high renewable energy penetration and affordable energy supply, for remote areas and customers.

In October 2017, EDF R&D signed a four-year Research Collaboration Agreement (RCA) with NTU to develop the MASERA project (Microgrid for Affordable and Sustainable Electricity in Remote Areas).

This EDF project, led by an R&D team based in France, Singapore and UK, involves a number of EDF Group entities (ENEDIS, spin-offs, R&D and engineering departments) as well as French and international partners.

Leveraging EDF R&D experience, skillsets and innovations, the project seeks a fully integrated microgrid, easily deployable, reaching local needs with an affordable electricity supply, and targeting packaged and plug & play solutions.

MASERA has been deployed in only one year by EDF and its key partners from basic designto full commissioning in October 2018. MASERA leverages the strong EDF Group international experience in designing, developing and operating distributed energy solutions. MASERA microgrid is now connected to the REIDS medium voltage grid from there on it will be a flexible testbed for various use cases (100% renewables, islanding, critical loads, voltage regulation) and technologies (storage, advanced controls) until 2021.
