Progress of Power Generation from Chinakuri Power Plant:

Through tendering, the job of repair/ refurbishment of the 3x10 MW Chinakuri Thermal Power Plant along with erection of 2 nos OHTL for evacuation of power has been awarded to M/s Imperium Energy Utility Services LLP. The repair/ refurbishment job has been completed and the final inspection is going on. Thereafter the trial run shall commence before the commercial generation. ECL shall save Rs. 7.80 Crore (for MGE of 1452 L.kwH (@ 53p/kwh) towards the energy output and shall earn annual lease rent of Rs. 4.54 Crore.

Energy Conservation & Audit:

In 2018-19, ECL had focused on energy conservation through improvement of power factor in most of underground mines. Also, steps are taken towards segregation of domestic load from industrial load.

Performance of CHPs:

As on 31^st March 2019, the Major CHPs handled 16.4 MT and Mini CHPs handled 2.6 MT of coal.

Major achievements during2018-19:

Total Power Consumption of ECL has been reduced to 8463.04 L. kWh in FY: 2018-19 from 8689.70 L. kWh i.e. reduced by 2.61 %.
Total Power Cost of ECL has been reduced to Rs. 611.07 Cr in FY: 2018-19 from Rs. 647.22 Cr in FY: 2017-18 i.e. reduced by 5.58%.
Penalty towards power factor has been reduced to 51.85 lakh in FY: 2018-19 from Rs. 87.91 in FY: 2017-18 i.e. reduction of 41%. For the rest points, paying power factor penalty, procurement of Capacitor Bank (1 no 225 kVAR for Mugma Area, 2 nos 600 kVAR for Rajmahal Area, 8 nos 450 kVAR and 9 nos 300 kVAR for different areas and ECL HQ, 2 nos 3x275 kVAR for Jhanjra Area) is under procurement process.
Specific Consumption of total excavation has been reduced to 5.29 kWh/ CuM in FY: 2018-19 from 5.85 kWh/CuM in FY: 2017-18, i.e. reduced by 9.62%.
ECL has taken step towards removal of own domestic supply to some units of Sodepur Area and simultaneously connected those load to WBSEDCL. ECL is paying bill amount for the on roll employees of company and thus saving considerable energy and power cost by avoiding unauthorized connection. The total consumption (industrial + domestic) of Parbelia and Ranipur colliery for March 19 is 5,12,773 kWh whereas the same was 11,63,228 kWh in March 2018. Thus, after segregation of domestic load the consumption has been reduced by 56%. The power cost has also reduced to Rs. 40,67,250 in March 19 compared to Rs. 1,00,33,744 in March 18, i.e. power cost has been reduced by 59.46%.
The company is in a process of replacing the old and outdated steam winders by electric Winders. One steam winder at Pit No.10 of Khas Kajora has been converted to Electric Winder.
