en.Wedoany.com Reported - The East Nusa Tenggara Regional Headquarters of PT PLN (Persero) (PT PLN Unit Induk Wilayah Nusa Tenggara Timur, UIW) has confirmed that the Oelpuah Solar Photovoltaic Power Plant (PLTS Oelpuah), located in Kupang Regency, East Nusa Tenggara Province, has become the main electricity supply source during the midday peak load period on Timor Island. With an installed capacity of 5 megawatts peak, the plant has been supplying clean energy to local residents since it began operation in 2016.
F Eko Sulistyono, General Manager of the PLN East Nusa Tenggara Regional Headquarters, stated during an on-site inspection of the plant in Kupang that PLTS Oelpuah continuously supplies green electricity to residents during the midday peak hours. The plant operates on a grid-connected system, directly linked to the PLN grid without battery storage, and therefore only runs from 06:00 to 18:00 local time. While this operational mode has limitations, it is highly effective for supplying power during the midday peak load.
PLN has collaborated with Independent Power Producers (IPPs) to optimize PLTS Oelpuah, operated by PT Surya Energi Indotama (SEI), as a concrete measure to reduce carbon emissions and preserve the natural sustainability of East Nusa Tenggara. PLN has committed to continuously providing reliable and clean electricity, emphasizing that strengthening the integration of the plant with the operational system is key to maintaining stable power supply in island regions and ensuring the reliability of Timor Island's clean energy-based electricity supply.
The Indonesian government is optimizing the utilization of photovoltaic power plants to achieve energy self-sufficiency goals under the "Asta Cita" policy framework. The country's total renewable energy development potential amounts to 3,687 gigawatts, of which 3,294 gigawatts come from solar energy. The operation of PLTS Oelpuah demonstrates that large-scale photovoltaic plants can reliably supply green electricity during midday peak load periods, reflecting PLN's commitment to the clean energy transition. Future synergies between PLN and IPPs are expected to strengthen further, which is crucial for optimizing Indonesia's vast renewable energy potential, particularly solar power, enabling the gradual achievement of energy self-sufficiency and carbon emission reduction targets. This grid-connected photovoltaic technology model can serve as a reference for photovoltaic project development in other regions of Indonesia, positioning the country as a promising leader in clean energy utilization in Southeast Asia.
