Description

The development of more efficient and least cost energy management interventions is of great importance for isolated energy systems. Islands are typical examples of isolated regions, often highly dependent on imported fossil fuels but with a significant and often unexploited Renewable Energy (RE) potential. This paper presents a least cost planning approach towards the integration of Renewable Energy Sources (RES) in such systems, which is applied to the island of Lemnos, Greece. The approach involves the application of Cost-Effectiveness Analysis (CEA) and Incremental Cost Analysis (ICA) for screening possible alternatives and determining the most economically efficient and effective plan for their implementation. The objective of the application of the proposed approach in the specific case study is to meet through the use of RE technologies all the additional electricity and thermal energy demand, compared to 2007. Various supply side options are evaluated, and an implementation plan is derived. The results indicate that the excess of both electricity and thermal energy demand can be met in the near future without any significant changes in existing infrastructure, while other options should be considered for a more extended time horizon.
