Indonesia has officially launched construction of its first ocean current power plant, marking a major milestone in the country’s renewable energy transition. The project, valued at approximately US$220 million, will generate 40 megawatts (MW) of power and is expected to be operational by 2028.
The development will occur in two phases of 20 MW each, with installations planned in East and West Nusa Tenggara. The initiative brings together international firms, including NOVA Innovation from the UK and Tidal Bridge from the Netherlands, along with local players such as PT Pertamina Power Indonesia.
“The plan is to develop it in East Nusa Tenggara Province by 20 MW and West Nusa Tenggara Province by 20 MW,” stated the Directorate General of New, Renewable Energy and Energy Conservation (EBTKE). “This is one of the steps to support the energy transition, energy security, and sustainable utilization of Indonesia’s marine potential.”
Indonesia’s vast coastline—spanning over 54,000 kilometers—gives it one of the highest marine energy potentials globally. The Ministry of Energy estimates the country’s marine resources could theoretically produce up to 160 gigawatts (GW).
The tidal power project, known locally as PLTAL, is part of Indonesia’s broader 2025–2034 Electricity Supply Business Plan (RUPTL), which targets 69.5 GW of new capacity, 76% of which will come from renewable sources and energy storage. This includes solar, hydro, wind, geothermal, and nuclear energy, with the remaining 24% derived from fossil fuels.
The PLTAL will incorporate diverse marine technologies, including tidal flows, ocean waves, temperature gradients, and salinity differentials. Officials hope the success of this initiative will encourage further investment and innovation in marine-based energy, supporting national energy independence and climate goals.
