The Power Plant units will be phased out between FY 2018-19 to 2020-2021

Altogether nine thermal power plant units including one central PSU, six units from state sector and two units from private sector will be phased out (closed) between Financial Year 2018-19 to 2020-2021 for not able to adopt Flu Gas De-suplhurization (FGD) technology as per the directive issued by the Union Ministry of Environment Forest and Climate Change (MoEFCC).


If all these units will be phased out as planned, the state will fall short by 1880 MW power.
The ill-fated thermal power plant units which are likely to be phased in Western Region due to non compliant as per new environment norms are - State Sector-two, 120MW units of CSPGCL Korba East Thermal Power Station (440MW) by December 2018 and March 2019 and four 210 MW units CSPGCL Hasdeo Thermal Power Station (840MW) Korba West between January 2020-December 2020.


Thus the Chhattisgarh State Power Generation Company Limited will acquire a shortfall in its power generation capacity by 1080 MW by end of financial
year 2020. Presently, the power generation in the state sector is around 2424 MW, which includes 2280 MW from Thermal power, 138.7 from Hydel power and 6MW from others (Bhoramdeo Co-gen). In the Central PSU
sector – one unit of NTPC Korba STPS (200MW) will be phased out by March 2021. NTPC has meanwhile urged for allowing flexible operations of the said unit, but any exemption or relaxation in this direction is subjected to permission from CEA/MoEFCC.

Similarly, in the private sector, two 300MW units of Lenco Amarkantak Ltd under Pathadi TPP will be phased out by December 2020.


It is worth mentioning here that he Ministry of Environment Forest and Climate Change (MoEFCC) in order to reduce emissions from thermal power plants has issued directives for installation of Flu Gas Desuplhurization (FGD) technology. According to the MoEFCC’s notification under fresh environmental standards, it has directed 65 per cent cut in particulate matters, 70 percent cut in Nitrogen Oxide (NOx) and 85 percent cut emissions of Sulphur dioxide (SO2).


Under this directive the thermal power plants will also need implementation of FGD technology for controlling SO2 emissions besides up gradation of electrostatic precipitators (ESP) and installation of retrofit boilers to reduce emission of particulate matters and NOx. Plants older than 25 years required closing down because installing pollution control mechanism in them would not be cost effective.


A special TCC meeting of Western Region Power Council was held on April 5 at WRPC Mumbai to discuss the single point agenda of phasing out of generating units which do not have space for installation of Flu Gas Desuplhurization (FGD) technology for compliance of new MoEFCC norms of SOx emissions. Also during a previous meeting held on the same agenda on March 24, the generators had raised issues of low voltage, over loading of transmission lines and Information and Communication Technologies (ICTs) and other related grid security concerns. However, these new environmental norms are to be complied within 2 years of notification. During the meeting the provisions of penalty in the Environment Protection Act is case of contravention were also discussed. During the meeting the WRCC asked the generators to provide firm date of phasing out of their respective units accordingly.


During the meeting the generators raised the concern that for installation of FGD they have to incur heavy expenditure. The cost of power would increase because of increase in auxiliary power consumption as well as for operations and maintenance cost. The WRCC advised the generators to take up this issue with CERC, CSERC or CEA.


The WRCC stated that there is no transmission constraint in WR as such and there will be no difficulty in availing shut down for commissioning of FGD.


During the meeting it was further directed that the generating units have to initiate the process of installation of FGD at the earliest since the progress of installation would be monitored accordingly on regular basis. As the Environmental Norms have to be complied by December 2017, the generators need to place the supply order latest by December 2017.
