A comparative study on the impact of solarising the Industrial area on DISCOMs is carried out during the project period of 4 months. Main DISCOMs of states like Karnataka, Andhra Pradesh, Gujarat along with a union territory Dadar and Nagar Haveli were taken into consideration as these states covers the main industrial sector of India.
This dissertation consists of mainly the financial impacts on the DISCOMs with the increase in solar rooftop installation in Industries of their licensed area. As the study was performed based on the secondary data only, it has been focused on few main parameters that govern the financial aspect of a DISCOM. There was no survey or site visit conducted during the project period. Microsoft Excel is used for the quantitative comparative study.
The project revolves around an attempt to study the main parameters that are affected due to the solarisation of the industrial consumers in the licenced area of a DISCOM. For this the information was extracted from the Tariff Orders, ARR petition, Annul Report from the official site of DISCOM.
Initial part of the dissertation consists of the study around the financial aspects of a DISCOM. The parameters that are considered in the ARR calculation were identified and among them the most important and study sensitive parameters were chosen. Further these parameters are extracted from each of the DISCOMs reports and a case study is carried out where required assumptions are taken in order to compare the effect of solarisation of Industrial area on all the DISCOMs performance.
All the 4 DISCOMs comparative study is performed based on percentage of solar installed in industrial sector and their respective impacts on various parameters like power purchase cost, revenue loss, Interest on working capital and REC cost of a DISCOM. Based on each parameter a comparison is done between 4 DISCOMs.
If Industrial sector are solarised such that 5% of the energy sold to industrial sector is covered through the RTS and hence not purchased by Industries from DISCOM, then it is calculated that the most affected parameter is the Revenue loss. Nonetheless it is countered by few hidden benefits like avoided Power Purchase Cost, avoided interest on working capital, and avoided REC cost. Among all 4 DISCOMs the PGVCL will have more severe impact whereas BESCOM will have the least among all. APEPDCL would initially gain but will gradually fall if percentage of solarisation increases further. DNHDPCL is vulnerable as well but since the market covered by it is comparatively small so impact on it lies in between others.
