摘要：To ensure sustainable development, the generation expansion planning (GEP) should meet the electricity demands in the specify time horizon. The GEP will determine the type and capacity of generator units to meet with the minimum cost, required reserve margin and energy balance. In this paper, a GEP to minimize the cost by considering the high penetration hydro energy potential was carried out in Sulawesi electricity region. GEP optimization is done by finding the minimum total cost value that is done through WASP-IV. There were two approaches for conducting the optimization that are regional balanced and resources-based approaches. The effect of renewable energy plant, especially the hydro energy, can be seen through a resource-based scenario, where the generating units were priories installed close to the energy source location. On the other hand, the regional balanced approach would install the generating units close to the load center. This paper compared the results of regional balance to the resource-based scenarios. The results show that resource-based approach can achieve a renewable energy power plant mix of up to 30%. The regional balance scenario total costs were $ 9.83 billion in low projection electricity demand and $ 13.57 billion in high projection electricity demand. On the other hand, the resource-based scenario total costs were $ 9.54 billion in low projection electricity demand and $ 13.38 billion high projection electricity demand.
