Handil is a mature field in Mahakam block which has been operating for more than 40 years. One of the challenges is to maintain the availability and reliability of the Electrical Power System. The existing load shedding system is not considering the available/reserve power and load priority. It is only managed by the relay system with high failure possibility. Automatic load shedding is one of the common tools that could be applied to the electrical network in order to maintain electrical system stability whilst provides continuous supply for essential loads. The aim of the paper is to introduce new load shedding design in Handil field as an improvement from semi-automatic to fully automatic system by utilizing the existing Control System facility. The new design of automatic load shedding system will be configured on Programmable Logic Controller (PLC). Hence, the entire protection requirement and power management scheme to maintain the availability of the electrical power system could be freely determine. The advanced electrical failure detection system will also be implemented e.g. a drop of network frequency and generator overheating due to overload. In order to strengthen the study and design of automatic load shedding logic, load calculation and online observation will be carried out. In overall, the new design of automatic load shedding system will complement the existing function and minimize unnecessary loads removal by the old load shedding function. This new load shedding design with minor modification in Handil field is a breakthrough idea to ensure production sustainability in a mature field. The last but not least, the study also will include the electrical power audit to define the load priority best on criticality which impact to the production activity. In addition, the load shedding action will minimize impact to production and will prevent electrical blackout during electrical power shortage.
