Jakarta, INTI - Pertamina's Director of Transformation and Business Sustainability, Agung Wicaksono, revealed that the implementation of a solar power plant (PLTS) on the Patra 2303 Oil Barge (OB) can reduce carbon emissions by up to 79.2 tons of CO2 per year and diesel fuel consumption.
Agung stated that the use of PLTS on oil distribution vessels demonstrates that efforts to reduce fossil fuel use can be implemented not only on land but also in the maritime sector, which currently relies on diesel as its primary energy source.
"The use of solar energy combined with batteries demonstrates that dedieselization can be implemented not only on land but also at sea. This represents Pertamina's readiness to support the acceleration of the energy transition," said Agung.
The installation and operation of the PLTS on the Patra 2303 Oil Barge is one of Pertamina's efforts to expand the use of clean energy throughout the company's business chain, including its fleet supporting energy distribution and national oil distribution.
The implementation of the PLTS on the oil barge also exemplifies collaboration between entities within Pertamina in providing more environmentally friendly energy solutions.
Indirectly, Agung believes that the synergy between PT Pertamina New & Renewable Energy (PNRE), PT Pertamina Trans Kontinental (PTK), and PT Pertamina International Shipping (PIS) enables solar power plant innovations that not only provide operational benefits but also support the national energy transition agenda.
Reduce Fuel Consumption and Carbon Emissions
Meanwhile, John Anis, President Director of PT Pertamina New & Renewable Energy, explained that the PLTS system used on the Patra 2303 OB vessel utilizes an off-grid PLTS with a capacity of 11.5 kilowatt peak (kWp) integrated with a 32 kilowatt-hour (kWh) Battery Energy Storage System (BESS).
John explained that the energy generated by the PLTS is used to support the power needs of the vessel's auxiliary engines, thus partially replacing the oil vessel's diesel consumption with renewable energy.
"The PLTS on the Patra 2303 OB vessel can substitute energy needs for up to six hours of vessel operation. With this implementation, fuel consumption can be significantly reduced," said Anis.
According to the company's calculations, the implementation of Pertamina's solar power plant has the potential to save up to 28.08 kiloliters of diesel fuel per year. This reduction in fuel consumption in the oil fleet also contributes to a reduction in carbon emissions of up to 79.2 tons of CO2 per year.
Conclusion
Pertamina installed PLTS on the Patra 2303 Oil Barge as part of efforts to decarbonize the maritime sector. The system used is an off-grid PLTS with a capacity of 11.5 kWp, integrated with a 32 kWh Battery Energy Storage System (BESS) to support the ship's auxiliary engine power requirements. This technology is able to replace the use of diesel energy for up to six hours of ship operation, potentially saving fuel consumption of around 28.08 kiloliters per year and reducing carbon emissions by up to 79.2 tons of CO2 per year.
