In 2018, the Association of Southeast Asian Nations (ASEAN) committed to meeting 23% of its primary energy needs from renewables by 2025. The region is aiming to leverage its abundant wind and solar resources and reduce its reliance on fossil fuels, especially as grid systems develop and economies grow. Wärtsilä's new 100 MW energy storage project will help provide some of the reliability necessary to support South East Asia’s transition to renewable energy sources.

Wärtsilä's GEMS platform has the ability to react near-instantly to smooth the integration of renewables, enabling the grid to be more stable and responsive. Grid support applications of GEMS include voltage and frequency regulation, reactive power support, spinning reserve, ramp rate optimisation, renewable energy output smoothing and energy arbitrage. GEMS will make it possible for grid operators to rely on renewables as baseload power.

Wärtsilä Energy Business has a delivered more than 35 EPC projects totalling 1500 MW in the South East Asia region.
