This research aims to explore the potential implementation of new and renewable energy (NRE) on the fleet of PT XYZ as part of the company's energy transition strategy towards Net Zero Emission (NZE) target by 2060. The maritime transportation sector is the main focus, given its high fossil fuel consumption and significant greenhouse gas emissions. This research uses a qualitative approach with a case study method, involving secondary data analysis, field observations on the installation and operation of solar power generation systems (PLTS) on Crew Boat vessels, and interviews with PT XYZ management, ship technicians, and relevant regulators. Problem identification is done through Pareto analysis and fishbone diagrams to find the root causes of high fuel consumption. The research results show that dependence on fossil fuel-based auxiliary engines, lack of renewable energy alternatives, and low operational efficiency are the main factors. As a solution, PT XYZ develops an NRE system consisting of 4 units of 550 Wp solar panels (PV String), 2.16 kWp DC / 2 kW AC inverter, and 10 kWh lithium battery. The implementation of this innovation results in significant fuel savings of up to IDR 463.37 million per year and CO2 emission reduction of 43.64 tons per year, as well as increased operational efficiency of the vessel. This research provides strategic recommendations for PT XYZ in realizing the company's sustainability vision and makes an important contribution to global efforts to reduce the impact of climate change.
