Virtual synchronous generator to help decarbonise electricity production

Seoul, South Korea, 23 Aug 2021 / PRNewswire / – Kokam Co., Ltd, a global provider of innovative lithium-ion battery solutions and a subsidiary of SolarEdge Technologies, has entered into a contract to supply Electricité de Tahiti (EDT), a subsidiary of ENGIE, with a Battery Storage System (BESS) serving as Tahiti’s first “virtual synchronous generator (VSG)”. Comprised of a 15MW / 10.4MWh battery system with an integrated 20Mvar STATCOM, the state-of-the-art BESS will replace EDT’s spinning reserve diesel generators to cost-effectively reduce power consumption. diesel fuel, allow more renewable energy and strengthen the grid. .

By incorporating more renewable generation sources and improving the performance of its diesel generator set, EDT can reduce fuel costs by around € 1.25 million per year. The VSG is also expected to increase savings in the form of reduced generator maintenance costs and extended generator operational life.

Ike hong, Chief Marketing Officer of Kokam, comments: “Electricité de Tahiti’s BESS demonstrates how innovative and intelligently designed battery solutions can help utility and industrial customers reduce their greenhouse gas emissions while improving their results and increasing network reliability.

Emphasizing the critical importance of the Kokam battery energy storage system in reducing fuel consumption without risking grid stability, François-Xavier de FROMENT, Chairman and CEO of EDT, comments: “Grace VSG technology, EDT is acting on its desire to decarbonize electricity production and contribute to the transition to carbon neutrality by French Polynesia. “
