Alternative spatial approach on spatial demand forecasting for transmission expansion planning

Spatial load forecasting for transmission expansion planning requires forecasting in long term and valid to a large area. Its characteristics are different from the characteristics of spatial load forecasting which has been developed which have a short term and for limitless or small areas. In this paper carried out a qualitative approach to obtain an alternative approach that can address these problems. The result is new definition of spatial units as a function of the centre of economic growth. Modeling carried out on Sumatra Island, which shows the location of the load center in accordance with the location of the center of economic growth. These results can be used as a basis for planning the magnitude and the delivery of power in transmission expansion planning.
