Development of Renewable Energy-Certified Onshore Power Supply in Indonesian Ports to Reduce Carbon Emissions

The implementation of the Onshore Power Supply (OPS) business at ports is one of the efforts to accelerate the energy transition in the maritime transportation sector. In the case study of one port in Indonesia, the use of OPS facilities has the potential to reduce carbon emissions by 4.19% or 127 MTCO2. If the use of OPS facilities can be increased for all ports in Indonesia, it can help accelerate the achievement of the Net Zero Emission target. This OPS business model involves several business entities including PT PLN (Persero) as the provider of electricity and infrastructure from the network/grid, the owner of the port business area as the investor and implementer of the OPS business, and the owner or operator of the ship. In terms of operational aspects and financial analysis, the feasibility of implementing OPS greatly influences the percentage of the number of ships docked using OPS facilities as well as tariff adjustments with an adjustment period every 2 years with an indicative IRR of 11 - 13%, Net Present Value IDR 2 - 3M, Benefit Cost Ratio> 1, and Payback Period 8 - 9 years. Even though there are tariff adjustments, the OPS business for ships is still more efficient than using fuel. To support the use of green energy, implementing the OPS business can be supported by purchasing a Renewable Energy Certificate so that electricity transacted from the OPS is recognized as renewable energy-based energy. In this case study, only 1 (one) REC unit is needed to run an OPS with a capacity of 4×250 kV A. Therefore, it needs support from various stakeholders, both from policy support and support from business actors.
