A Study of Wave Energy for Electrical Power Generation at Songkla Area in Thailand

The aim of this paper is to analyze the investment of the electrical power generation from the wave energy at the Gulf of Thailand in order to develop the electricity production from the wave energy which is green energy. The performance of wave energy converter (WEC) is evaluated at the Songkla area by using the available wave data, which is adopted from the Marine Meteorological Center. There are two parts in this research. The first one is the electrical power calculation which is the calculation of electrical production by using the Pelamis transformer which depends on the significant wave height (Hs) and the wave period (Tp) at the Gulf of Thailand. The other is the economical analysis, which is the key performance indicator by using the benefit to cost ratio (B/C ratio) and the net present value (NPV) to analyze the potential of investment by comparing with the present electrical fee.
