The project will help to provide the reliability that is required to support South East Asia’s shift to renewable energy sources.

Wartsila’s new power storage system includes an advanced energy management software platform GEMS and GridSolv solution that has been designed and developed to support the electric grid.

The company noted that its GEMS platform can facilitate smooth renewables integration, enabling the grid to become more stable and responsive.

To support the grid, the platform is equipped with voltage and frequency regulation, reactive power support, spinning reserve, ramp rate optimisation, renewable energy output smoothing and energy arbitrage.

Wartsila has been developing a wide array of flexible systems that can be integrated with the traditional thermal assets and energy storage systems to support the transition towards 100% renewable energy across the world.

In 2018, the Association of Southeast Asian Nations (ASEAN) announced a commitment to meeting 23% of its primary energy needs from renewables by 2025.

The Asian countries plan to use available wind and solar resources and reduce their dependence on fossil fuels.

Wartsila Energy Business delivered more than 35 EPC projects with a total capacity of 1500MW in the South East Asia region.

In July 2019, Wartsila secured an engineering and equipment (EEQ) contract to supply additional capacity for a power plant owned and operated by the national electricity technology company Kahraba.
