Renewable Energy Potential Index

Before anyone models a plant, they need to know whether a place is worth modelling. This service answers that: a single normalised index per location, derived from long-term solar irradiance and wind resource records, so that candidate areas across a region, or across countries, can be ranked on the same scale in one pass.

The underlying quantities are: global horizontal and direct normal irradiance for solar, wind speed and power density at the relevant hub heights for wind, both from multi-decade satellite-derived and reanalysis datasets, terrain-corrected. Because the records are long, the index carries not only a central estimate but the variability around it.

What turns resource data into an index is combining it with the factors that make good resource usable: terrain slope, distance to grid, distance to road.
