Global Prospects for Utility-Scale Solar Power: Toward Spatially Explicit Modeling of Renewable Energy Systems

by Kevin Ummel

- This paper provides high-resolution estimates of the global potential and cost of utility-scale photovoltaic and concentrating solar power technologies and uses a spatially explicit model to identify deployment patterns that minimize the cost of greenhouse gas abatement. A global simulation is run with the goal of providing 2,000 TWh of solar power in 2030, taking into account least-cost siting of facilities and transmission lines and the effect of diurnal variation on project profitability and required subsidies. The American southwest, Tibetan Plateau, Sahel, and Middle East are identified as major supply areas.
