Table 1 . Location of SHPs sites and Existing Substation of UPCL
Figure 2. 53N/8 Topographic Map Showing Four Corners contours, which are the base lines showing the elevation of the surface points. In such cases, two methods are used to draw the transmission line routing: (a) To survey and prepare the map by surveying instruments and estimating the optimum value or the shortest feasible path for the transmission line routing. This approach is very difficult and time consuming, and there are likely chances of getting more length of transmission line resulting in high cost and more line losses. (b) Another approach is to use the software to generate Digital Elevation Model (DEM) by ArcView of the area of interest, and carrying out the transmission line routing by visual sense of the DEM. A comparison of different alternatives of connecting the SHPs provides optimum option for line routing. The cost as well as the technical feasibility of the routing of the transmission line can be analyzed without real survey. Using ArcView, transmission line routing is very cost effective and time saving. Since there is no need to survey the area, and once the digital data are generated, it can be used for long period of time. The following inputs were used for determining the elevation of the points and spot heights: i. Values of contours and spot heights of topographic map ii. GPS (Geographical Positioning System) receivers iii. Total station (surveying instrument) Total station has been used to provide the elevation by manual measurements at site. Using the topographic map, the values of contours as well as the spot heights were obtained directly.

The supply of power to remote rural areas in India from Small Hydropower Projects (SHP)/renewable en-ergy power projects in cost effective and sustainable manner requires the optimum design of mini-grids. The present paper deals with the design of mini grids of nine SHP plants presently running in isolated mode only for 8 hrs/day wasting the energy of 16 hrs/day. Based on system layouts, transmission routing, line length and selection of conduc-tor, 5 different alternates of mini-grids were developed to connect these SHPs together as well as with the nearby 33 kV grid substations located at approximately 15, 17 and 9 km from nearby SHPs in order to improve the load factor. The optimization of these alternates on the basis of the Break Even Point (BEP) has indicated that Alternate-V has been found as optimum alternative for the study area with shortest line length, low line losses and minimum capital investment for the mini-grid implementation.
