PT. Geo Dipa Energi has a plan to optimize the Dieng unit's operations and achieve the installed capacity about 60 MW for Unit-1. To achieve the targets that have been planned, PT. Geo Dipa Energi conducted a program with Surface Facilities in the HCE 9B well. Front end engineering design (FEED) is a crucial phase in engineering design. The goal of doing a FEED is to minimize significant changes during the construction phase. The achievement of this activity was to demonstrate the work of the front-end engineering design (FEED) is proposing a design solution for the steam above ground system (SAGS) at the Dieng Unit-1 geothermal area. The FEED methodology is based on equipments design for example piping systems, separator, silencer, cooling ponds, pumps, and finally economic analysis . FEED's work on the steam above ground system (SAGS) in the geothermal area contains the wellhead facility system to the steam pipe transmission. The SAGS technical design will be determined the result of the activity. As a recommendation to improve the results of this activity, activities must cover subsystems and make use of the software in their modeling as HYSYS V8.8. The results of the analysis show that the HCE 9B well generates 6.33 MW. Every equipment that has been designed will be calculated for its economic aspects to validate the feasibility of the project. It was recorded that the initial investment needed was around IDR 40.5 billion. Based on these figures compared to total revenue, the payback period (BEP) is calculated for 10 months, so this project is attractive and feasible to run.
