Kokam Supplies Battery Energy Storage System to Electricité De Tahiti: Virtual Synchronous Generator to Help Decarbonize Electricity Generation

2021. 08. 23

Kokam's Lithium-ion NMC battery technology cost-effectively provides high-power output to replace the network’s spinning reserve diesel generators.


Seoul, Korea - Kokam Co., Ltd, a global provider of innovative lithium-ion battery solutions and a subsidiary of SolarEdge Technologies, has entered into contract to supply Electricité de Tahiti (EDT), a subsidiary of ENGIE, with a Battery Energy 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 in order to cost-effectively reduce diesel fuel consumption, allow more renewable energy and strengthen the grid.  


By incorporating more renewable generation sources and improving the performance of its diesel genset, EDT may reduce fuel costs of approximately up to ~€1.25M per annum. The VSG is also expected to increase savings in the form of reduced generator maintenance costs and the extension of generator operational lifespan.

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 lower greenhouse gas emissions while also improving their bottom line and increasing grid reliability.”

Emphasizing the critically of Kokam’s Battery Energy Storage System in reducing fuel consumption without risk to grid stability, François-Xavier de FROMENT, Chief Executive Officer of EDT, comments: “Through the VSG technology, EDT acts on its desire to decarbonize electricity production and contributes to the shift to carbon neutrality in French Polynesia.”
