INTRODUCTION The areas that rapidly increase the electricity demand in Indonesia are South Sulawesi and Central Sulawesi. these regions have potential electric power with Central Sulawesi electrification ratio reached 48.3%. Based on the potential, will be built hydro electric power Poso-1 dam located in the Saojo village, North Pamona, Poso, Central Sulawesi. This hydropower in addition to serve the needs of the area around the project (Central Sulawesi), are also expected to support the electricity needs throughout Sulawesi, particularly the mining industry spread across South and Southeast Sulawesi. 2. ELECTRICAL SYSTEM IN CENTRAL SULAWESI Up to the third quarter of 2014, the electrical system of Central Sulawesi Province is supplied by power plant generator centers, diesel and hydropower with total installed capacity is 314 MW with the composition of the plant is still dominated by diesel-fueled HSD amounted to 224.1 MW, or 71 % of total generating capacity, followed by hydropower for 63 MW or 20% of the total generating capacity of 27 MW and a power plant or 9% of total generating capacity. With the completion of construction of 150 kv transmission network Poso-Palu will maximize the evacuation of power from Poso hydropower electricity system, Central Sulawesi. 2.1. Electricity Projection Needs in Central Sulawesi With the implementation of Special Economic Zones (SEZ) in the Palu city, in the future economy of Central Sulawesi will certainly increase. Almost all sectors of the economy will grow up. In order SEZ can running well, the electricity supply needs to be strengthened in order to support the Government's program. Based on electricity sales data within 5 (five) years and taking into account regional economic growth trends including the regional industry, population growth and increased electrification ratio on future, the projected demand for electricity from 2015 to 2024 can be seen in the following table: 400
