Geographic information systems (GIS) tools are used to identify areas suitable for the development of solar photovoltaic (PV) plants. Once the suitable areas have been identified, the electricity generation potential of each project opportunity area is quantified in terms of resource quality, capacity factor, and levelized cost of electricity. Each potential project area is also assigned several attributes which provide additional information on the characteristic of the project area and its degree of suitability. The study is conducted using GIS maps and data, and a set of tools specifically developed by the Lawrence Berkeley National Laboratory to identify the potential project areas. The methodology consists essentially of three stages: (1) identification of all viable land by applying exclusion criteria; (2) division of the included areas into spatial units; and (3) calculation of area attributes and levelized cost of electricity (LCOE) for each potential site.
