Analysis of Levelized Cost of Kuroshio Energy in Taiwan (SDEWES2016.0024)
Taiwan is surrounded by sea with 1,566 km of coastline. A primary assessment of marine energy that incorporates the energy reserves, derivative economic benefit, cleanness and sustainability, energy stability, and cost competitiveness shows that wave energy, thermoelectric energy, and marine current energy have the greatest potential for development in Taiwan. Among them, the fixed direction of current flow gives it a great deal of potential for power generation, and thus it has started to draw attention in many counties. The Kuroshio off the east coast of Taiwan is part of the global ocean current system. If ocean current power generation technology can be successfully developed, its power generation efficiency would be greater than that of intermittent energy such as solar and wind. Power generation from the Kuroshio can provide the base load electricity in Taiwan, increasing Taiwan’s self-sufficiency rate and safety of energy. However, the initial phase of developing the Kuroshio power generation in Taiwan requires huge capital investment, and issues such as economic benefit and market competitiveness must be considered.
The levelized cost of electricity (LCOE) for natural gas-fired in the main island of Taiwan is about 3.6 NTD/kWh, and the average cost of electricity in Green Island (one of Taiwan's Offshore Islands) is about 13.5 NTD/kWh. In order to let Kuroshio power be competitive in market, this report presents an analysis of the LCOE for the development of Kuroshio power generation under three different scenario in Taiwan, 2MW, 30MW and 110 MW scenario respectively. Based on the scenario analysis of Taiwan's first 30MW Kuroshio power demonstration farm development, the LCOE is around 4.86-11.17 NTD/kWh at a discount rate of 15%, which is still higher than TaiPower's natural gas power generation cost of 3.57 NTD/kWh. In order to increase the industry’s willing to invest in Kuroshio power development, it is necessary to have the support from the government. Taiwan government could formulate marine spatial planning properly, doing preliminary investigation to zone the area suitable for Kuroshio power development, it would reduce more project cost.
