Pertamina-MEDCO E & P Simenggaris JOB (Join Operating Body)’s HSE department determined to build an Operation Supporting Facility on location SSB-06 Simenggaris village, Tarakan, East Kalimantan. In that area, an integrated project of the first green station in Indonesia will be established. Green station should meet the requirement of renovation and operation that follow the principle of energy saving and make a positive effect for environment, economy, and society. The drafting of this final assessment aims to obtain the system design of renewable energy for 720 kWh/day green station with the help of conventional energy as minimum as possible. To complete this purpose, the methods implied are to do theoretical study about standalone renewable energy system feasibility in Simenggaris, make a sistem model, and create an application program before execute the simulation to obtain the basic design of standalone renewable energy system. From the result of location survey, the suitable type of energy to be used are solar and water (micro hydro). At day time, a 150kW solar panel will convert solar radiation to electricity. The electricity produced will be partly used directly and the other part will be used to operate three 55kW pumps to move water from 15.500m3 size lower reservoir to 31.000m3 size upper reservoir. At night, water from upper reservoir will be flowed down to turn a 25 kW turbine. Effort to optimized electricity needs, energy availability, and financial advisability was done to choose the appropriate load. In 20 years, the system will produce Rp. 1.731.319.574,00 profit for the investor if the system was designed with the capacity of 503% from the initial load.
