TDI
without Geologic Influence
The TDI is ratio of the Technical Challenge Index (TCI) to the Power Production Potential (PPP) at a specific site.
The most attractive area will have a TDI close to 1; the TDI value will increase when the cost or challenge increases or
when the potential power diminishes.
