750kv GIS leak rate

750kv GIS leak rate

The Leakage/Surplus Factor, an Esri exclusive calculation, is the result of a more sophisticated approach for normalization of the gap between supply and demand. The result is an index scaled to upper and lower bound values ranging from -100 to +100. Using the Leakage/Surplus Factor allows users a simple way to identify business opportunity.
