Abstract
A multi-site, multi-device and multi-criteria decision support tool designed to support the development of tidal current energy in the Philippines was developed. Its platform is based on Geographic Information Systems (GIS) which allows for the collection, storage, processing, analyses and display of geospatial data. Combining GIS tools with open source web development applications, it becomes a webGIS-based marine spatial planning tool. To date, the webGIS-based tool displays output maps and graphs of power and energy density, site suitability and site-device analysis. It enables stakeholders and the public easy access to the results of tidal current energy resource assessments and site suitability analyses. Results of the initial development showed that it is a promising decision support tool for ocean renewable energy project developments.
Highlights
Ocean renewable energy (ORE) represents a significant resource for clean renewable electricity generation (Georgia Tech Research Corporation, )
Through the application of geographic information systems, this study aims to identify the Philippine’s potential sites for conversion of tidal current energy and, at the same time, develop a webGIS-based marine spatial planning (MSP) tool for site analysis
To determine suitable sites for tidal current energy development from the potential areas identified during resource assessment, a Geographic Information Systems (GIS)-based multi-criteria decision analysis (MCDA) was performed considering physical, environmental and socioeconomic factors as criteria [3]
Summary
Ocean renewable energy (ORE) represents a significant resource for clean renewable electricity generation (Georgia Tech Research Corporation, ). Sites where available tidal current energy occurs in large quantities are those sites where the flow is constricted, resulting in higher current stream velocities. These properties are exhibited by channels and straits which can be found in many areas in the Philippines considering that the country is an archipelago surrounded by vast ocean. Potential sites for each TISEC device will be identified through site-device matching This will help countries and organizations plan the use of their ocean resources (fishing, maritime and energy uses) with more efficiency and awareness (OES and EIA, )
