What is energy storage in Indonesia?

Energy storage systems serve varying purposes across different regions of Indonesia, particularly when comparing the Java–Bali–Sumatra grid, which has a high penetration of photovoltaic (PV) and wind installations, to other regions. In Java–Bali–Sumatra, energy storage primarily addresses the variability of RE sources, such as PV and wind.

Why do Indonesian batteries need a battery energy storage system?

Batteries are required to provide constant electricity supply to renewable energy plants, which are primarily intermittent, such as solar and wind power plants. The agreement was made with other state-owned bodies, such as the Indonesian Battery Corporation, to build the Battery Energy Storage System by 2022.

Can re and energy storage improve energy security in Indonesia?

These findings underscore the potential of a strategic combination of RE, optimized energy storage, and grid enhancements to significantly lower costs and enhance energy security, offering valuable insights for policymakers and stakeholders for Indonesia’s transition to a sustainable energy future. 1. Introduction

What is thermal energy storage?

Thermal energy storage (TES) can help to integrate high shares of renewable energy in power generation, industry and buildings. This outlook identifies priorities for research and development.

Are renewables a good source of energy in Indonesia?

As shown in Fig. 2 Despite an overall boost in energy generation, renewables only slightly improved their contribution to the energy mix, from 11.24 % to 13 %, with hydro and geothermal sources registering modest increases (Ministry of Energy and Mineral Resources Indonesia, 2023). Fig. 2.

Do energy storage systems provide virtual inertia?

Literature supports that energy storage systems (ES) can be instrumental in providing virtual inertia and are critical for the frequency regulation of power systems with high penetration of renewable energy sources (Fernández-Guillamón et al., 2019).
