# Control Technologies August 29, 2008

Introduction In the June 18, 2008 meeting between th e Public Service Company of New Mexico (PNM), Black & Veatch (B&V), a nd the New Mexico Environment Department – Air Quality Bureau (NMED), the NMED requested additional analyses be performed for the Nalco Mobotec NO x 

# control technologies. Speci fically, the NMED requested additional consideration and modeling of the ROFA with Rotamix, Rotamix, and ROFA
NO x 

# control technologies. As described in the June 6, 2007 BART application document and in PNM’s March 31, 2008 response to NMED questions, th e ROFA technology is a type of overfire air (OFA) system, and the Rotamix technology is a version of SNCR cont rol technology. The NMED requested that ROFA and Rotami x be analyzed separately from other LNB/OFA technology and SNCR, respectively.

Part 1 - Engineering Impact Analysis At the request of the NMED, an engineering impact analysis was performed for the Nalco Mobotec NO x 

# control technologies. The result s of that impact analysis are
shown in Attachment 1. Table 7-1 in Attach ment 1 is a modificat ion to the Table 7-1 found in PNM’s original BART submittal of June 6, 2007 and also the update submitted on May 30, 2008 to include SNCR. The ta ble has been updated to include the engineering impact of the Nalco Mobotec NO x 

# control technologies. In addition to Table 7-1, Attachment 1 also includes th e least cost curves for all NO x 

# control technologies evaluated for BART, detailed cost tables for installing Nalco Mobotec NO x 

# control technologies, cost development notes providi ng the basis for the ROFA cost estimates, and design concept definitions fo r each Nalco Mobotec technology

. 

# In the response submitted to the NMED on March 31, 2008, a technical evaluation of the Nalco Mobotec NO x 

# control technologies was performed. The evaluation performed forms the basis of th e engineering impact analysis for this supplemental BART analysis. The BART analysis is based on the de monstrated experience of the Nalco Mobotec technologies. There is one installation of ROFA in units above 300 MW. This
installation is for a confidentia l Northeast client (570 MW). Also, there is one operating
installation of Rotamix in units above 300 MW; Sutton Station Unit 3 (424 MW). It should also be noted that the ROFA a nd Rotamix applications over 300 MWs both

## 2 of 12 

# combust different fuels than SJGS. The Bo swell Unit 4 (565 MW) is currently in the process of installing Rotamix, but to B&V’ s knowledge, the Rotamix system is not in operation yet. It should be noted that the application of Rotami x at Sutton produces higher emissions (lb/MBtu) th an the Nalco Mobotec budgetary quote for PNM. There are no units greater than 300 MW in ope ration with both the ROFA and Rotamix technologies. Nalco Mobotec does have un its with ROFA and Rotomix technologies under the 300 MW size, but these units are si gnificantly smaller than the SJGS units and were not considered represen tative for this discussion. In the engineering impact analysis, the cost estimates include contingencies to retrofit the ROFA fan to the existing site and the additional auxili ary energy consumption of these fans used to impart kinetic energy to the overfire air system to promote turbulent mixing during combustion. Due to the large additional amount of kinetic energy required for the rotating overfire air system, the auxi liary energy consumed by the ROFA fans is significantly higher than the LNB/OFA system currently installed to meet consent decree requirements. At NMED’s request, the control effectiveness presented in this supplemental BART analysis document for the ROFA, Rota mix, and ROFA with Rotamix technologies are the values from Nalco Mobotec’s quotati on. The ROFA technologies are based on operating the furnace at a lower burner stoichiometric ratio (BSR) of 0.84 than the currently designed value of 0.90.

Control Effectiveness of Na lco Mobotec Technologies

Technology Control Eff ectiveness (lb/MBtu)
ROFA with Rotamix 0.20
Rotamix 0.23
ROFA 0.26

Also included in the updated Table 7-1 are the cost effectiveness evaluations previously completed and submitted for other NO x 

# control technologies. The cost
effectiveness values are for additional NO x 

# removal from the cons ent decree level. As stated previously, this anal ysis of the Nalco Mobotec technologies was done at the request of the NMED. B&V and PNM do not agree that Nalco Mobotec’s offerings should be differentiated from the other ve ndors that supply overfire air systems and selective non-catalytic reduction systems.

## 3 of 12 

# Nalco Mobotec has no specific documente d operating experience with the SJGS coal. The fuel burned at SJGS is unique. It does not easily fit into either a bituminous or sub-bituminous fuel category. As previously mentioned, the new low NO x 

# burners, which were installed for the consent decree would most likely need to be modified to optimize NO x 

# performance with the ROFA technology. On August 15, 2008, B& V had a telephone c onversation with
Nalco Mobotec to better understand how thei r technology works. In this conversation,
Nalco Mobotec stated that their technol ogy can be operated at a lower boiler stoichiometric ratio, in part, because of the changes that they would likely make to the new low NO x 

# burners. The burner modifications will, in effect, detune the new state-ofthe-art B&W low NO x 

# burners to reduce the NO x 

# reduction performance by the burner. These changes would consist of physically modifying the burners to improve mixing. This work is typically performed by extern al consultants hired by Nalco Mobotec to redesign the burner systems. Nalco Mobotec st ates that this impr oved mixing will reduce the potential for corrosion and temperature imbalance. This increase in turbulence and mixing at the burner in most cases results in higher flame temperature and more rapid
combustion close to the burner. The result w ould be expected to be less unburned carbon and less potential for flame impingemen t on the opposite boiler walls which would reduce the potential for fireside wate rwall corrosion from overheating and flame impingement. Without these modifications, th e previously discussed potential impacts of operating at this lower BSR may include corrosion due to the reducing environment in the boiler and impacts to the steam temperatures due to changing the location of the
fireball. It should also be noted that even with the burne r modifications, B&V continues to be concerned about the potential for incr eased slagging as well as the unproven nature of the Nalco Mobotec technology with the SJGS coal and units in this size range.
The control effectiveness used as the evaluation basis in this supplemental BART analysis is dependent on successfully addres sing all of these concerns to avoid any negative impacts to the SJGS plant operations and availability rate. Meanwhile, other
NO x 

# control technologies (LNB wi th OFA) are installed or be ing installed that have all these technical concerns already addressed. For Rotamix, there is only one unit with Rotamix above 300 MW. This unit does not produce the low level of NO x 

# quoted by Nalco Mobotec for PNM. In comparison, Fuel Tech has 17 commercial SNCR only (not in combination with other Fuel Tech technologies) installations and 3 demonstrat ion installations on uni ts greater than 300 MW. Fuel Tech has significantly more expe rience with SNCR on units in the size range of SJGS. Therefore, B&V and PNM have greater confidence in the performance guarantee quoted by Fuel Tech. B&V and PNM are not comfortable with the technology

## 4 of 12 

# risk that PNM would incur if a permit limit was applied to the SJ GS that was based on the quote received from Nalco Mobotec. Furthermore, there is not a significant difference between the Fuel Tech quotation and the Nalco Mobotec quotation to warrant the risk that PNM would incur. Lastly, for the combination of ROFA with Rotamix, the lower control effectiveness value proposed by Nalco Mobo tec in comparison to the LNB/OFA with SNCR approach submitted in the May 30, 2008 update is due to the a lower starting (uncontrolled) NO x 

# level. With the ROFA technology, uncontrolled NO x 

# for Rotamix is 0.26 lb/MBtu. While for LNB/OFA, the uncontrolled NO x 

# for SNCR is 0.30 lb/MBtu. Both Rotamix and SNCR then reduces NO x 

# by approximately 20% to 0.20 lb/MBtu and 0.24 lb/MBtu, respectively. Therefore, it is observed that the incremental NO x 

# reduction in terms of percentage is very simila r between the ROFA with Rotamix and the
LNB/OFA with SNCR combinations.

Part 2 – Visibility Analysis Subsequent to the June 6, 2007 submittal, PNM further investigated additional
refinements to the BART CALPUFF air di spersion modeling analyses which included nitrate repartitioning and mo re realistic ammonia background concentrations based on monitored values at several western Class I areas. These additional modeling options are considered more realistic and therefore will again form the basis of this analysis. To date, PNM has previously submitted four BART modeling analyses in addition to the Wet ESP analysis being submitted separate ly but coincident with this analysis. To clarify the contents of these analyses, as we ll as for this submittal, a summary of each has been provided: June 6, 2007 Modeling analysis were performed to provide SJGS plant-wide regional haze (visibility) impacts at 16 Class I areas. The analyses were based on a constant 1 ppb background ammonia concentration a nd no nitrate repa rtitioning. The NO x 

# control technologies analyzed were the Selective Catalytic Reduction (SCR) and SNCR/SCR Hybrid.

November 6, 2007 Modeling analysis were performed to provide SJGS plant-wide regional haze (visibility) impacts at 16 Class I areas. The analysis was based on refinements which included using the nitrate repartitioning methodology and monthly variable background ammonia concentrations. Again, the NO x 

# control technologies analyzed were the SCR and SNCR/SCR Hybrid.

## 5 of 12 

# March 31, 2008 Two main modeling analyses were perfor med to provide SJGS plant-wide and unit specific regional haze (visibility) impacts at 16 Class I areas for the SCR NO x 

# control technology only. One of the analyses, believed to be the more representative of ammonia chemistry of the area, was based on the November 6, 2007 refinements which included using th e nitrate repartitioning methodology and monthly variable background ammonia c oncentrations. The other analyses included nitrate repartitioning and a c onstant background ammonia concentration as requested by the NMED.

May 30, 2008 Two modeling analyses were performed to provide SJGS plant-wide and unit specific regional haze (visibility) impact s at 16 Class I areas for the SNCR NO x 

# control technology only. Similar to the March 31, 2008 analyses, one of the analyses was based on the November 6, 2007 refinements which included using the nitrate repartitioning methodology and monthly variable background ammonia concentrations. The other analyses incl uded nitrate repartitioning and a constant background ammonia concentration. It s hould be noted that all vendors of SNCR (including Fuel Tech and Nalco Mobotec) have been modeled together as one technology called SNCR. This is the same approach that is used for modeling SCR control technology, where all vendors are modeled generically as SCR.

August 29, 2008 Three modeling analyses were performed to provide SJGS plant-wide and unit specific regional haze (visibility) impact s at 16 Class I areas for the ROFA with Rotamix, Rotamix, and ROFA NO x 

# and WESP PM control technologies (the NO x 

# and PM analyses were submitted separately). Similar to the May 30, 2008 analyses, these analyses were also based on the November 6, 2007 refinements which included using the nitrate repartitioning methodology and monthly variable background ammonia concentrations.

The modeling refinements contained in this submittal using nitrate repartitioning and the variable ammonia background as we ll as the previous November 2007, March 2008, and May 30, 2008 submittals supersedes the original June 2007 BART modeling analyses as PNM believes these analyses are more representative of regional conditions in the modeling domain, as well as, allow for a more representative visibility analysis.

## 6 of 12 

# Information pertinent to these two refinements has been included in de tail in the previous four submittals. Furthermore, at the June 18, 2008 meeting NMED indicated that based on a current ammonia monitoring study conducte d by Mark E. Sather of EPA Region VI, the previous analyses provided utilizing the variable ammonia were representative of the surrounding background. Therefore, no other analyses were performed using nitrate repartitioning and constant background ammonia.

Visibility Summary Based on the refinements methodology cons isting of representative background
ammonia concentrations and ni trate repartitioning, revised CALPUFF visibility modeling was performed for five cases ; pre-consent decree, consen t decree (which represents SJGS’s BART baseline scenario), ROFA with Rotamix, Rotamix, and ROFA NO x 

# control technology scenarios. The modeling summari zed in this report is for the SJGS on a plant-wide basis and for each of the four SJ GS units on an individual unit basis. It is important to note that all other modeling optio ns as described in the BART application were unchanged. For simplicity, the following results discuss the differences between the
consent decree scenario and the NO x 

# control technology scenarios. The stack outlet conditions for the NO x 

# control technology scenarios are included in Attachment 2 and the visibility modeling results are contained in Attachment 3.

SJGS Facility Visibility Summary wit h Nitrate Repartitioning and Variable Ammonia The results of the refined visibility m odeling for the SJGS plant, assuming the same control technology is inst alled on all four units, are illu strated in Tables 1 through 6 of Attachment 3. These tables summarize the scenarios and the maximum visibility (deciview) impact seen at any of the 16 Class I areas at any time over th e 2001 to 2003 period. The results of this analysis, using the aforementioned refinements, indicates a minimal improvement in visibility impact (less than 0.5 dv) at each of the 16 Class I areas when compared to the baseline (consent decree) scenario. The maximum visibility (deciview) impr ovement seen at any of the 16 Class I areas at any time over the 2001 to 2003 period is illustrated in Table 6 for each scenario. The expected degree of visibility improvement for each control scenario for each unit (on a plant-wide basis) was determined by the difference in the maximum visibility improvement for each receptor at each of the si xteen Class I areas. Again, it is important to note that the control technology associated with the consent decree formulated the SJGS’s baseline case, as well as the base line case for the individual unit analyses described later. Additionally, the cost-eff ectiveness for the potential BART control

## 7 of 12 

# technologies from the BART application were used to calculate visibility improvement cost-effectiveness in $/decivi ew ($/dv). Three major scenarios are shown in the visibility improvement cost effectivene ss summary in Table 6 for each control technology:

• Pre-consent decree to consent decree.

• Consent decree to additional NO x 

# control technology alternative scenarios.

• Pre-consent decree to additional NO x 

# control technology alternative scenarios.

These maximum visibility improvements between the consent decree and the three NO x 

# control technology scenarios range fr om 0.04 dv to 0.34 dv of expected visibility improvement above the consent d ecree scenario. The vi sibility improvements for each of the Nalco Mobotec control technology options are summarized below:

• Facility improvements with ROFA/Rotamix range from 0.09 dv to 0.34 dv.

• Facility improvements with Rotamix range from 0.09 dv to 0.25 dv.

• Facility improvements with RO FA range from 0.04 dv to 0.21 dv.

The results indicate that adding additional NO x 

# control technology beyond the consent decree does not yield visibility impr ovement greater than 0.5 dv at any Class I area. In fact, as previously noted, the maxi mum visibility improvement at any of the 16 class I areas is only 0.34 dv. Based on the visibility improvement mode led and the total annual cost evaluated in the impact analysis stage of the BART a pplication document, the cost-effectiveness for visibility improvement (annual cost per improve ment in visibility, $/dv), was determined for SJGS over the aforementioned range of visi bility improvement. The resulting cost for installation of Nalco Mobotec NO x 

# control technology for all f our units ranges from $464 million/dv to $69 million/dv. The visibility improvements for each of the Nalco Mobotec control technology opti ons are summarized below:

• ROFA/Rotamix range from $369 million/dv to $97 million/dv.

• Rotamix range from $269 million/dv to $69 million/dv.

• ROFA range from $464 million/dv to $82 million/dv.

Attachment 3 contains a SJGS plant-wide summary of the 98 th 

# percentile visibility impact for the three modeled technology sc enarios (i.e., Pre-Consent Decree, Consent

## 8 of 12 

# Decree, ROFA/Rotamix, Rotamix, and ROFA scenarios), provides information on the number of days above 0.5 dv threshold, and indicates the contribution of each pollutant associated with the 98 th 

# percentile visibility imp act for each class I area.

Unit Specific Visibility Summary wit h Nitrate Repartitioning and Variable Ammonia
The results of the refined visibility modeling for Unit 1, Unit 2, Unit 3, and Unit 4 are illustrated in Tables 7-12, 13-18, 19-24, a nd 25-30 of Attachment 3, respectively.
These tables summarize the scenarios and the maximum visibility (deciview) impact seen at any of the 16 Class I areas at any time over the 2001 to 2003 period. Similar to results seen for the SJGS facility, the visibility impacts at Mesa Verde, in many cases, represent the maximum visibility impact at any of the 16 Class I areas. In addition, this analysis indicates a minimal improvement in visibility impact (less than 0.5 dv) at each of the 16 Class I areas when compared to the ba seline (consent decree) scenario. The maximum visibility (deciview) improve ment seen at any of the 16 Class I areas at any time over the 2001 to 2003 period is illustrated in Tables 12, 18, 24, and 30. Again, the expected degree of visibility impr ovement for each control scenario for each unit was determined by the difference between the consent decree’s maximum visibility improvement for each receptor at each of the sixteen Cla ss I areas and the specific NO x 

# control technology scenario’s maximum visibility improvement for each receptor at each of the sixteen Class areas. Furthermore, the same methodology previously described for the SJGS’s cost-effectiveness in ($/dv) was used here for each unit. These maximum visibility improvements between the consent decree and the NO x 

# control scenario for each unit are similar to that of the combined SJGS. The visibility improvements for each scenario are summarized below.

ROFA/Rotamix

• Unit 1 improvements range from 0.02 dv to 0.23 dv.

• Unit 2 improvements range from 0.02 dv to 0.23 dv

• Unit 3 improvements range from 0.05 dv to 0.24 dv

• Unit 4 improvements range from 0.04 dv to 0.24 dv

Rotamix

• Unit 1 improvements range from 0.02 dv to 0.17 dv.

• Unit 2 improvements range from 0.02 dv to 0.18 dv

• Unit 3 improvements range from 0.02 dv to 0.17 dv

• Unit 4 improvements range from 0.03 dv to 0.18 dv

## 9 of 12 

# ROFA

• Unit 1 improvements range from 0.01 dv to 0.11 dv.

• Unit 2 improvements range from 0.01 dv to 0.12 dv

• Unit 3 improvements range from 0.0 dv to 0.12 dv

• Unit 4 improvements range from 0.01 dv to 0.12 dv

The results again indicate that adding additional NO x 

# control technology beyond the consent decree consisting of ROFA/Rot amix, Rotamix, or ROFA does not yield visibility improvement greater than 0.5 dv at any Class I area. Based on the visibility improvement modeled and the total annual cost evaluated in the impact analysis stage of the BART application document, the cost-effectiveness for visibility improvement (annual cost per improvement in visibility, $/dv), was determined for each unit for each Class I area. The resulting cost for installation of additional control technology for each unit is summarized below.

ROFA/Rotamix

• Unit 1 cost range is $322 million/dv to $33 million/dv.

• Unit 2 cost range is $308 million/dv to $29 million/dv.

• Unit 3 cost range is $209 million/dv to $41 million/dv.

• Unit 4 cost range is $224 million/dv to $40 million/dv.

Rotamix

• Unit 1 cost range is $197 million/dv to $21 million/dv.

• Unit 2 cost range is $187 million/dv to $20 million/dv.

• Unit 3 cost range is $214 million/dv to $28 million/dv.

• Unit 4 cost range is $176 million/dv to $27 million/dv.

ROFA

• Unit 1 cost range is $432 million/dv to $30 million/dv.

• Unit 2 cost range is $384 million/dv to $29 million/dv.

• Unit 3 cost range is $1,281 million/dv 1 

# to $43 million/dv.

• Unit 4 cost range is $512 million/dv to $42 million/dv.

## The visibility improvement realized for Unit 3 is 0.004 dv but is illustrated in Attachment 3, Table 24 as 0.00 dv.

## 10 of 12 

# Attachment 3 also includes a unit sp ecific summary of the 98th percentile visibility impact for the three modeled te chnology scenarios (i.e., Pre-Consent Decree, Consent Decree, ROFA/Rotamix, Rotamix, a nd ROFA scenarios), includes the number of days above 0.5 dv threshold, and indicates the contribution of each pollutan t associated with the 98th percentile visibility impact for each class I area.

Additional Considerations The minimal visibility improvements discu ssed in this document for the variable ammonia case do not merit the large capital expenditure required to install ROFA/Rotamix, Rotamix, or ROFA NO x 

# control technology. In ad dition to the high cost and minimal visibility improvements associated with these technolog ies, there are other important reasons that LNB, OFA and NN s hould be considered BART for the SJGS units. First, the LNB, OFA and NN system s are being installed to meet the consent
decree are state-of-the-art combustion contro ls. State-of-the-art combustion controls comprising of LNB, OFA and NN technologie s were used to form the basis for the BART presumptive limits for NO x 

# in the BART guidelines. Second, the ROFA NO x 

# control technology is a LNB/OFA technology in which SJGS already has installed or will soon be in the process of inst alling on their four generating units. Third, the visibility results imply that visibility is influenced mo re by the SJGS’s sulfur emissions than by the
reduction of NO x 

# . However, sulfur emissions are not subject to BART requirements because New Mexico participates in the WRAP emissions trading program. Fourth, installation of SN CR, ROFA/Rotamix or Rota mix requires ammonia to
reduce NO x 

# emissions. Specifically, in a SNCR syst em, urea is injected into the boiler and this will decompose into ammonia for the NO x 

# reduction process. Any unreacted ammonia passes through the bo iler and out the stack as a mmonia emission s or ammonia slip. This additional ammonia would then be available to add to the ammonia background concentration, chemically react to fo rm nitrates and sulfates, and potentially further increase the visibility impacts at the Class I areas. The additional ammonia slip was not considered in this analysis. Fifth, as described in Part 1, the Nalco Mobotec ROFA or ROFA/Rotamix system requires detuning of the new LNB systems coincident with the installation of the ROFA system. This causes a potential negative scenario if a forced outage occurs with the ROFA fan system. Without the ROFA fa n to complete the combustion process, the detuned LNB, which has significantly higher NO x 

# emissions than the tuned LNB, will quite likely result in a forced outage of the unit to avoid exceedance of the NO x 

# emissions limit. This results in lost generation for PNM. This scenario may be avoided

## 11 of 12 

# in a LNB/OFA system since the increase in NO x 

# emissions when the OFA system is out of service will be minimal when compared to the ROFA system. Finally, PNM entered into a consent decree with the Grand Canyon Trust, Sierra Club, and NMED on March 10, 2005, to settle alle ged violations of the Clean Air Act.
For NO x 

# control, the settlement required installation of state-of-the-art NO x 

# combustion controls which was deemed to be new LNB with OFA and a NN system. All four units
will have these controls insta lled by the spring of 2009. Due to the nature of the consent decree requiring the approval of and installatio n of state-of-the-art combustion controls to achieve a specific NO x 

# emission limit, detuning of this LNB system to increase NO x 

# emissions as part of the RO FA or ROFA/Rotamix may be prohibited without additional legal action. At a minimum, all parties iden tified in the consent decree may have to agree to the proposed modification should ROFA or ROFA/Rotamix be determined by NMED
to be BART.

Conclusion As noted in this document, PNM’s furthe r investigation of additional refinements to the June 2007 BART CALPUFF air disper sion modeling analyses to yield more realistic regional haze impacts was warrant ed. These analyses included nitrate repartitioning and more realistic amm onia background concen trations based on monitored values at several western Class I areas, as well as, the additional ammonia study being conducted by EPA in New Mexico. The conclusi on of this study re-iterates and further supports the overall findings of the original June 2007, as well as, the three aforementioned additional submittals, that installation of additional NO x 

# control technology systems at the SJGS provide mi nimal visibility improvements and would require significant capital expenditure and modifications that will impact many areas of the plant including boiler draf t systems, air heater performance, and ash handling. The results from the analyses further substant iate that the addition of ROFA/Rotamix, Rotamix, or ROFA NO x 

# control technology does not yi eld a benefit nor meet the intended goal of BART. Specifi cally, these analyses indicate:

• The addition of ROFA/Rotamix, Rotamix, or ROFA NO x 

# control technology on a plant-wide or individual unit basis shows less than a 0.5 dv improvement for all Class I areas including the four Cla ss I areas located in New Mexico.

• Both the total annual costs evaluated and the cost-effectiveness ($/dv) are prohibitive given the minimal improvements realized.

• Although B&V has received additional clar ifications from Nalco Mobotec on the ROFA technology, B&V and PNM continue to have concerns about the potential

## 12 of 12 

# for slag using the ROFA system, Nalco Mobotec’s lack of experience with the fuel burned at SJGS, and Nalco Mobotec’ s minimal experience with units of a
similar size to SJGS.

4.1 ROFA System Cost Inputs: Nalco Mobotec proposal costs (dated 2/1/2008) SJGS 1 or 2 ROFA/Rotamix = $8,782,220 SJGS 3 or 4 ROFA/Rotamix = $9,987,917 SJGS 1 or 2 Rotamix only = $2,101,687 SJGS 1 or 2 Rotamix only = $2,336,853

Calculation: ROFA System Cost = ROFA/Rotamix cost – Rotamix only cost SJGS 1 or 2 ROFA System Cost = $8,782,220 - $2,101,687 = $6,681,00 SJGS 3 or 4 ROFA System Cost = $9,987,917 - $2,336,853 = $7,651,000

Notes/Remarks: Reference cost was based on Nalco Mobotec proposal (February 1, 2008) for ROFA/Rotamix and Rotamix only systems.

4.2.a Combustion System Modi fications (SJGS 1 or 2) Inputs: Reference unit cost (18 burners) = $650,000 (previous B&V project with ROFA) Reference unit burner heat input = 133.3 MBtu/hr PNM (U12) burner heat input = 231.7 MBtu/hr PNM (U12) number of burners = 16

Notes/Remarks: Reference cost was based on a preliminary quotation. Final aw arded contract was $779,450. The final price also included sampli ng fans at a price of $17,555 for 2 units. Pricing used for SCR cost estimate (2 reactor s). Cost for ROFA is for 1 system only (half).

# 3 4.4 Electrical System Upgrades 

# Electrical system upgrades fo r the ROFA fans are base d on the total electrical system modifications and new transformer for the new ID fans in the SCR project cost estimates. This is based on the assumption th at similar electrical system upgrades are required for the relatively similar sized fans between the ROFA and SCR projects.

The attached table shows a breakdown of the cost estimate for electrical/control

modifications of the PNM SJGS , required if an SCR were in stalled. The cost estimate was developed based on reference to the project cost of other reference units where B&V performed a balanced draft conversion. A scaling and retrofit factor was used to determine the engineering & materi al and construction labor costs. The total direct cost is the summation of the engineering and material, and

construction labor costs.
