Abstract: This study is a part of three projects carried out at TERI-SRC, Bangalore. The first project
was undertaken for Karnataka Electricity Regulatory Commission (KERC) to perform a
Prudence Check of the capital expenditure incurred by Karnataka Power Transmission
Corporation Limited (KPTCL). A sample of all KPTCL project works (categorizing cost
above and below Rs. 5 crores) taken up during the FY10-12 for improving the quality and
reliability of power supply were studied and graded according to the KERC guidelines.
KPTCL executed a total of 260 project works during the three financial years which consists
of setting up new sub-stations with associated line, new transmission lines and augmentation
of transformers in some existing sub-stations. To carry out Prudence Check, samples of
project works consisting of 81 project works (above Rs. 5 crores) and 113 of 179 project
works (below Rs. 5 crores) were selected as per the KERC guidelines. The main aim of this
study was to verify if the objectives achieved by the implemented project works justify the
amount invested. Any expenditure not fully justified by the objectives would mean that the
customers are burdened with cost of redundant investments in the form of tariff hike. Of the
194 project works (81 above Rs. 5crores and 113 below Rs.5crores) considered, 189 project
works were found to be satisfying prudent norms and 5 project works were not satisfying the
prudent norms. Based on the finding in the study, some suggestions were given to KERC.
The second part was a comprehensive energy audit of Sugar industry with co-generation and
Distellary, located in Karnataka. The project consisted of taking electrical and thermal
measurements of different processes as well as utility equipment to find out the energy
consumption and evaluate their performance useful towards identifying potential energy
savings. After taking the readings, the data was analyzed and applicable energy efficient
measures were suggested.
The third part was a comparison study of energy savings and payback periods of different
IEC standard efficiency class motors with respect to ordinary motors of same rating.
