Analysis on the implementation of energy management and conservation: Case study: Pemaron gas power plant

Energy conservation especially in thermal power plant has been used energy management concepts developed by experts. Some experts develop energy management models that focus on standardized elements such as boiler efficiency, generation heat rate, turbine heat rate, specific fuel consumption and auxiliary power consumption. Other experts develop energy management models based on energy audits. In this study both approaches are used to evaluate the energy conservation process. Results of both approaches are compared to get the most appropriate approach will be possible to be implemented in Indonesia. In the case study that conducted at Pemaron Gas Power Plant in Bali, the standard approach is only done on auxiliary power consumption and SFC, the approach succeeded in reducing power plant auxiliary power consumption from 1.24 GWh to 0.56 GWh in 4 years. Power plant SFC successfully derived from 0.427 l/kWh to 0.411 l/kWh in 4 years. While the energy audit approach hard to be implemented because the power plant is standby. Application of the standard approach with a focus on the 5 elements can reduce the cost of energy management with good results makes it more attractive to be applied. The result of this study could be used by similar power plant model to be more efficient especially in auxiliary power consumption.
