Annexure-I

Minutes of meeting held on 17.01.2017 for Preparation of Phasing Plan for

implementation of new Environmental Norms for Thermal Plants

The list of participants is enclosed at Annexure-A.

1. Member Secretary welcomed the delegates and briefed regarding the objective of the meeting. He informed that NRPC had been given the responsibility of preparing the phasing plan for the identified units in the Northern Region for FGD installation and ESP up gradation in consultation with all the entities for implementation of new Environmental Norms for Thermal Plants.

2. CEA representative gave a presentation on the implementation of new

environmental norms for Thermal Power Stations. He informed that the revised norms were notified by MoEF&CC in December 2015 making norms for SPM, SOx, Nox, and Mercury and water consumption more stringent. The new Standards would require installation of specific pollution control equipment for SOx and NOx control and augmentation of ESPs for complying with more stringent SPM Standards. He stated that the FGD installation and ESP up gradation for compliance of new norms for more than 40 GW capacity, based on coal and lignite in Northern Region need to be finalised in such a manner that power supply position in the country/ region is not impacted.

3. He informed that for SPM control Retro-fitting of additional fields in ESP/

replacement of ESP or application of other suitable technologies would be required to achieve the proposed norms in the existing plants. For SOx control FGD system would need to be installed to meet the amended norms for all categories of existing plants as well as plants under construction. However, availability of space for installation of FGD may be a constraint.

4. Regarding the NOx control he stated that the proposed standards of 600 mg/Nm3

may require modification of the combustion process using low NOx burners and the proposed standards of 300 mg/Nm3 and 100 mg/Nm3 would require installation of de-nitrification systems like Selective Catalytic Reduction (SCR) or Selective Non-catalytic Reduction (SNCR) systems. It was informed that NTPC has taken up 8 pilot projects for installation of SCR/SNCR to see their suitability for the Indian coal.

5. CEA representative informed that a Committee was constituted by Ministry of

Power in September 2016 for preparing a phasing plan for implementation of new environmental norms. He briefly described the recommendations of the committee. Based on the recommendation of the committee units having space for FGD installation were identified for FGD installation and the same had been

4

sent to respective RPC’s for preparation of phasing plan. He emphasized that power supply position in the region need to be taken care of while preparing the phasing plan.

6. It was informed that as per data available with CEA, a capacity of 19660 MW (39

units) has space for installation of FGD systems in Northern region. He suggested that phasing plan for installation of FGD system in these units may be prepared. He also stated that the new units may be taken first in the implementation process.

7. It was also informed that in the units having CFBC systems in Northern region

would likely to control SOx level to the desired levels and up-gradation of ESP system may be taken up in these units to control SPM norms.

8. Regarding the short listing of particular units for FGD installation and ESP up-

gradation, he stated that the list had been prepared based on information available with CEA. He requested all the utilities to check the list and inform correction, if any.

9. NTPC representative gave a detailed technical presentation on the Various Sulphur Dioxide Emission control Technologies. Copy of NTPC presentation is uploaded in NRPC website. The process of Flue Gas Desulphurization was explained and the available options like Dry and Wet Type FGD were also discussed. On a query raised by the different entities it was stated that as per experience of NTPC for engineering, design, approvals and placing of order, a period of approximately three year would be required. Therefore, installation would only be feasible starting from last quarter of the year 2019-20, if the activities are started now.

10. It was deliberated that keeping in view, the time line for pre- installation activities,

the phasing plan should be prepared starting from January,2020. It was also deliberated that the shut down requirement would be about 6 weeks for the installation of FGD or up-gradation of ESP.

11. The representatives of the many utilities whose units are identified for installation

of FGD or up-gradation of ESP raised issues which they said need to be addressed before implementation of new environmental norms. The issues raised by different utilities are briefly described as under:

A. Punjab State Power Corporation Limited- (GHTP Lehra Mohabbat &

GGSSTP Ropar)

PLF of PSPCL units is too low (i.e about 35%) and the units were running only for about 5 months in a year. When the units are started after long shutdown

5

5

period, SPM value sometimes goes above the norms and comes down on stabilization of the unit on full load. Therefore, average value of SPM/NOx should be considered for the period of unit operation for meeting the environmental norms.

B. LANCO Anpara Limited

For water consumption, clarification is required regarding the defined PLF and the period over which it is to be calculated, as higher water consumption per MWh of generation at lower PLF is unavoidable.

For the new norms of SOx and NOx emission, the period i.e. instantaneous/daily/weekly/monthly average needs to be clarified. Also, it needs to be explained whether the weighted average is applicable in case of part load operations. The O2 percentage, to which the new SOx and NOx norms value is to be corrected needs to explained. Testing methods are also required to be defined.

The height of the chimney as per the new norms needs to be looked into. The feasibility of constructing a new chimney instead of doing the lining of the existing chimney needs to be weighted upon as the latter will require longer shutdown. The requirement of minimum exit velocity of 25 m/s needs to be reduced to accommodate for chimney internal lining or due to reduced height of chimney.

C. Nabha Power Limited

Space is available for installation of FGD at the power station but whether the same will sufficient for hundred percent flue gas is yet to be ascertained.

As there is a common chimney for both units hence shutdown for both units will be required.

Shutdown for phasing plan can be decided only after detailed engineering and firm commitment is obtained from the supplier.

D. GVK Power (Goindwal Sahib) Limited

Expenditure incurred for installation of these facilities should be considered as capital cost and should be paid as part of capacity charges in tariff.

The cost for implementation should be considered as per actual. Once these facilities are implemented the clean energy cess being charged

presently should not be payable. Shutdown period should be considered as deemed generation period and

capacity charges should be paid for the shut down period

6

Necessary directions should be given to the power purchasers to support the cost to be incurred for these facilities when the proposal is submitted to regulator.

It is not practical to implement these facilities unless and until the cost incurred is approved as part of part of capital cost by the regulator. No lender would come forward without Regulator’s approval.

Implementation of these facilities without permanent coal linkage may not be prudent.

Policy for disposal of Gypsum needs to be reviewed. The clearances required for low height chimney should be looked into.

E. Harayana Power Generation Corporation Limited

Whether up-gradation of ESP and installation of FGD are to be done

simultaneously. As per CEA estimates it requires a capital expenditure of Rs. 0.75 Crore per

MW for installation of FGD, retrofit of ESP and installation of NOx burners. However, the cost towards chimney lining / installing of low height chimney was not included. Also the implication of installing SCR/SNCR not included. Further, the loss on account of the shutdown of both units of RGTPP as chimney was common is also not included in the estimate given by CEA. It was envisaged that the capital cost expenditure will come up to 1 Crore/MW and financial implication of tariff will be Rs. 0.65 per unit. It was proposed that heavy financial expenditure should be met with the clean energy cess being paid by the plants.

The installation of FGD will result in increase in water consumption hence the norms for specific water consumption for a plant need to be revised.

The period by which the implementation is to be done be increased by 3 years.

The avenues of disposal of Gypsum and source of high quality lime stone needs to be looked into.

The approval period of reduced chimney needs to be got reviewed.

F. Lalitpur Power Generation Co. Ltd.

The technology and design of the FGD as per Indian conditions and Indian coal have to be ascertained. Original equipment supplier has to ensure the timely supply of equipment as they may turn out to be single source of supply and demand may be high.

There is no clarity on recovery of cost by regulatory commission, this is required to be clarified first otherwise funding shall be an issue. Whether additional tariff on account of additional cost of installation of FGD will be passing through is still unclear, till regulator response is known.

Project has to find the source of funding before proceeding further and bankers and financial institutions have to agree for the additional cost of funding.

The norms fixed for SOx level is very stringent and it is not known whether these are achievable or not after even installing the FGDs and incurring huge expenditure.

Installation cost of FGD as per CEA i.e. Rs. 0.5 Crore/MW is too less. As per present offer received by other operator, the cost will be too high. The cost of installation of FGD should also include extra water requirement, disposal of polluted water, source of good quality of lime stone and its crushing units, installation of three temporary chimneys and lining of existing Chimney, disposal of GYPSUM & long shutdown period of units etc. As such, before knowing the above inputs, it is difficult to assess the impact of additional cost of FGD.

Cost of installation of FGD will affect the Tariff which could be determined only after knowing the above inputs and the actual PLF of the individual project, regulators response on this is unknown so far.

Impact on Tariff at 50 % PLF as suggested by CEA is difficult to arrive at in absence of firm cost of FGD including other inputs. It should be PLF based. The projects having PLF even below 50 % also needs to be perused after installing FGD and its effect on tariff to be ascertained.

Petitions of some of the stake holders to treat this as Change of Law are pending in CERC, there outcome is awaited.

Ideally installation of FGD should be taken as a Pilot project by major players in the sector and the results of the same needs to be examined and analyzed before proceeding further to ascertain if it is having the desired results. The technologies for Indian coals should be decided before introducing FGD on power projects. Its effect on tariff too is to be resolved to secure funding by Banks & Financial Institution.

In our project at Lalitpur all three Units have one common chimney. Thus, for lining of existing chimney, three temporary Chimneys have to be build and as such more time is required for shut down for lining. During long shut down period, who will bear the fixed cost?

Increase of greenhouse gas due to excess auxiliary power consumption. As per NTPC, Installation of FGD will take 3-4 years. In view of this deadline

of Dec. 2017 may be extended to another 3-4 years. G. Bajaj Energy Limited (BEL)

SPM level in these units varies from 40-60 mg/ Nm3. BEL is in touch with the Suppliers of CFBC boilers to reduce SPM level within the present limits so that the matter can be resolved without installation of new equipment.

H. TALWANDI SABOO LIMITED

Approval from Procurer i.e. PSPCL for incurring expenditure on installation of FGD etc. – Keeping in mind the tentative expenditure of around Rs. 2,500 crores. (Operating expenditure shall be in addition to this) as indicated by our consultant M/S Tata Consulting Engineers, this huge expenditure cannot be undertaken till there is clarity on its reimbursement from the procurer i.e. Punjab State Power Corporation Limited (PSPCL) in our case. It may be noted that such huge expenditure will not be financed by Bank/ financial institution till there is clarity on its reimbursement from the Procurer.

Time line for implementation should be extended till December 2022 as almost 202 plants need to implement the FGD and other associated equipment’s whereas there are only select few suppliers. Also, as indicated by our consultant M/S Tata Consulting Engineers the implementation will take minimum of around 3 years from the date of start of the work subject to availability of equipment’s in time.

It needs to be clarified that norms as specified by MoEF & CC regarding NOx, SOX etc. are to be met only during stable operation period and not during special conditions like ramp up, startup, part loading, closing down etc.

A meeting with CEA is also required to address all these concerns and other common issues as highlighted by other power plants during the said meeting in conjunction with MoEF & CC and others concerned.

I. RVUN JAIPUR Huge capital expenditure is major concern hence financial tie up

possibilities being looked into. The issue of capital expenditure and in principle increase in tariff to be

analyzed Also availability of limestone and disposal of gypsum major concern.

12. It was deliberated that all the stakeholders would send their comment regarding

issues in FGD installation and ESP up-gradation work within a week.

13. Regarding various technical, financial, commercial, regulatory issues raised by the utilities Member Secretary, NRPC clarified that the present mandate to NRPC Secretariat is limited to preparing phasing plan. The concern of the sissues in implementation should be raised at appropriate forum. After detailed deliberation it was agreed that phasing plan may be prepared considering following aspects:

9

9

a) FGD installation phasing would be done for the identified units having space for the same.

b) ESP up-gradation phasing would be done only for those identified units which have CFBC boilers.

c) About 3 years would be required for pre- installation activities, therefore, the phasing plan should be prepared for the installation of FGD, where space are available, starting from January,2020.

d) For the units, where FGD installation is planned, having common chimney , new low height chimney would be constructed for each unit to avoid longer shut down required for existinmg cimney lining etc..

e) The anticipated demand – supply scenario of each state and Northern Region would taken into consideration while preparing the plan. The actual shutdown requirement may be different as per the grid conditions prevailing at that time.

f) The time for shutdown would be taken as 6 week, each for FGD installation and ESP up-gradation works.

Regenerative activated coke technology (ReACT) is a dry scrubbing system and involves three stages.Adsorption Stage - The exhaust flue gas comes in contact with a slow moving bed of activated coke pellets on a conveyor system. SO2, NOx and mercury are absorbed when coming in contact with the pellets.

Regeneration Stage - The activated coke pellets containing the SO2, NOx and mercury are transferred to a thermal regenerator, where reactions take place and the pollutants are released into a sulfur gas stream.This is done in the regenerator vessel by pre-heating, heating and then cooling the pellets. The pellets are returned to the absorption stage. The absorbed mercury is then collected in the bottom of the vessel.

By-Product Recovery Stage - The sulfur-rich gas containing the SO2 and NOx flows to an adjacent acid recovery plant where a good quality sulfuric acid is produced, stored and prepared for re-sale.

PREPARATION OF PHASING PLAN FOR

IMPLEMENTATION OF NEW

ENVIRONMENTAL NORMS FOR THERMAL

POWER STATIONS

NORTHERN REGION

23

23

GENERAL

The draft Amendment for new environmental norms was circulated byMoEF&CC in March 2015 for views/ comments of the stake holders.

The revised norms were notified by MoEF&CC in December 2015 makingnorms for SPM, SOx, Nox, Mercury and water consumption morestringent.

The power projects were broadly classified into three categories i.e.plants commissioned before 31.12.2003, plants commissioned after01.01.2004 till 31.12.2016 and plants under construction to becommissioned after 01.01.2017.

The new Standards would require installation of specific pollutioncontrol equipment for SOx and NOx control and augmentation of ESPsfor complying with more stringent SPM Standards.

Northern Region has more than 40 GW capacity which is based on coaland lignite which shall be affected by the new environmental norms.

The implementation process need to be phased out in a manner thatpower supply position in the country/ region is not impacted.

MAJOR TECHNICAL ISSUES FOR EXISTING PLANTS

SUSPENDED PARTICULATE MATTER (SPM)

Retro-fitting of additional fields in ESP/ replacement of ESP or application of other suitabletechnologies would be required to achieve the proposed norms in the existing plants.

SULPHUR DIOXIDE (SOx)

FGD system would need to be installed to meet the amended norms regarding SOx controlfor all categories of existing plants as well as plants under construction.

Units of less than 500 MW size and some older 500 MW units may not be in a position toinstall FGD system due to non-availability of space.

A capacity of around 18 GW in Northern Region may be affected to non-availability of spacefor FGD.

OXIDES OF NITROGEN (NOx)

The proposed standards of 600 mg/Nm3 may require modification of the combustionprocess using low NOx burners

The proposed standards of 300 mg/Nm3 and 100 mg/Nm3 would require installation of de-nitrification systems like Selective Catalytic Reduction(SCR) or Selective Non-catalyticReduction(SNCR) systems.

The globally available SCR/SNCR systems for NOx control are not proven for Indian coalhaving high ash contents.

CONSTITUTION OF COMMITTEE FOR PHASING PLAN

A Committee was constituted by Ministry of Power in September 2016 for

preparing a phasing plan for implementation of new environmental norms.

The committee consisted of members from CEA, MoEF&CC, CPCB,

POSOCO, NTPC and DVC with Chairperson, CEA as the Chairman of the

committee.

The Committee conducted two meeting on 21.10.2016 and 13.12.2016 at

New Delhi.

Committee collected unit-wise data on all India basis from power utilities

and CPCB regarding present SPM norms, present SPM levels and space

availability for installation of FGD system of all thermal power stations.

The units below 25 MW and units recommended by CEA for retirement or

replacement with new super-critical units were not considered for phasing

plan.

27

27

Recommendation of the Committee

Units for which SPM norms have been made more stringent or the units emitting

SPM appreciably higher than revised norms were identified for ESP upgradation.

Units having space for FGD installation were identified for FGD installation.

The region-wise lists of the units were sent to respective RPC’s in December 2016

for preparation of phasing plan. Power supply position in the region need to be

taken care of while preparing the phasing plan.

Installation of FGD shall also control SPM, therefore, units may opt for FGD

installation to control SPM emission also to avoid double expenditure if technically

feasible. ESP upgradation may also be taken up if such arrangement is technically

not possible.

Suitable modifications in the combustion process like installation of low Nox

burners, over-fire systems etc. may be taken up by the utilities to control Nox

emissions in the next shut-down period.

To control Nox levels to 100 and 300 mg/Nm3, DeNOx systems like SCR or SNCR

may be required. For ascertaining the suitability of SCR/SCNR for high ash content

Indian coal, NTPC is installing pilot projects at 8 units.

28

28

Recommendation of the Committee As per information collected, a capacity of 19660 MW (39 units) has space for

installation of FGD systems in Northern region. A capacity of 18030 MW was installedafter 31.12.2003 and 1630 MW was installed before 31.12.2003.

A capacity of 1320 MW (2 units) has already installed FGD system in Northern region.

A capacity of 2030 MW (22 units) have already installed CFBC systems in Northernregion which is likely to control SOx level to the desired levels.

A total capacity of 13,869 MW (72 units) (excluding plants with FGD space) does notmeet the new SPM norms and may require ESP upgradation. A capacity of 6800 MWwas installed after 31.12.2003 and a capacity of 7069 MW was installed before31.12.20103. Another capacity of 5640 MW also does not meet revised SPM norms buthave space for FGD installation.

The phasing plan for implementation of new norms need to be prepared keeping inview that power supply position is not hampered in the country/ region.

The new units may be taken first in the implementation process.

The phasing plan need to be completed within one month time so that the committeerecommendations may be submitted in due time.
