Sumba Island is located in eastern Indonesia and was originally known as Sandalwood Island (as it exported sandalwood). Sumba Island is home to over 600,000 people and is one of the Lesser Sunda Islands, and is in the province of East Nusa Tenggara.

The VRB ESS will provide real and reactive power to Sumba, a small island in eastern Indonesia that has poor power supply. Using the ESS, the grid can support power to the island when the main grid is interrupted. This will in turn generate a smooth output of power, increasing the renewable accommodation capability. The PCS100 ESS battery solution can help energy storage devices, such as batteries, achieve stable storage and release of electrical energy
through frequency modulation and voltage regulation. For a power system, PCS100 ESS is just like a conventional synchronous generator featuring power electronics and advanced control technologies. Its inertial characteristics depend on the internal control system, which is aligned to the grid frequency and its change, and energy conversion is recognized on this basis.
