Page 1 V DEQ Conceptual Description for the Inclusion of Distributed Generation Units in Base Year and Future Year Modeling Efforts **Issue:** VDEQ has identified the need to examine more closely in modeling studies the e ffects on ozone air quality of distributed generation units. **Background:** Distributed generation units are mainly internal combustion engines that participate in some type of demand response program. These are small units, each usually no more than 2 or 3 megawatts in capacity, and they generally run on distillate fuel oil Most are permitted for well under 100 tons of NOx emissions annually and do not run frequently. A nnual emissions of NO X 

## are usually not very large from these units . However , o zone season dail y emissions estimates from p re vious ozone SIPs show that facilities that have one or more of these types of units can be quite significant NO X 

## emitters when examined on an **ozone season daily basis**  . For instance, in 2002 in the Northern Virginia portion of the metro DC ozone nonattai nment area, the inventory estimate for point sources include s about 60 tons/day of NO X 

## . EGU’s account for 40 tons/day of NO X 

## . Distributed generation units account for just over 10 tons/day NO X 

## . In 2002 for the Northern Virginia region, distributed generation units were the second largest point source NO X

## - emitting category, and many new facilities of this type have been permitted since 2002. In Northern Virginia especially, but across the Commonwealth, demand response programs are gaining in popularity, and utilities are actively recruiting participants. Such demand response programs are very helpful in maintaining the integrity of the power grid during high demand days or times when power capacity in small areas with transmission constraints is being ta xed. However, older units can have very high emissions, and control strategies do exist to significantly reduce NO X 

## from these units. Previous modeling efforts minimized the effects of these units on air quality because the annual emission rates were n ot very large (less than 100 tons/year NO X 

## ) and because the default profile of 365 days of operation annually was applied to the annual emission rate in the modeling inventories. This calculation methodology greatly minimized the impacts from these units. VDEQ would like to facilitate the review of these units for potential future control strategies by creating a profile for distributed generation that more accurately reflects operating conditions. Such a profile will limit operations of such units to a small er, more representative number of days during the year and to a limited number of hours during each day , as dictated by actual operating data . NOx emissions on a daily basis will therefore increase as compared to the daily NO X 

## emissions based on the default profile. NO X 

## emissions will also vary from day to day, depending on the number of hours of

Page 2 operation for that day. Once these units are more accurately represented in base year emissions inventories and modeling platforms, control strategy runs m ay be performed to determine if controlling these units will improve ozone air quality in the Northern Virginia/metro DC area. **Methodology :**  To more accurately characterize emissions from distributed generation, VDEQ intends to follow these steps in the i nventory and modeling process. 1. Inclusion of DG units in the Emissions Inventory: The first step is to ensure that as many distributed generation units are included in th e base year inventory as possible. Often agencies use 10 ton s /year of any criteri a pollutant as a cutoff for inclusion of point sources in the point source modeling inventory. VDEQ u s ed a 10 ton/year level to ensure that as many units were captured as possible, while screening out sources with emissions that are too small to be of any consequence . However, VDEQ also included stack/point/segment combinations identified by the regional office or by EIA data as distributed generation units , regardless of emissions rates. These line items were identified by county plant identifiers as wel l as stack, point, segment identifiers. 2007 data w ere retrieved from CEDS on these line items, and this data was provided to the regional planning organization (MARAMA) as well as the base year emissions inventory contractor (MACTEC). A listing of the i dentified DG units in the 2007 base year in ventory is contained in Table 5 . The table identifies if the unit was originally part of the 2007 inventory or if it was added to the inventory as a DG unit. 2. Identification of DG units: VDEQ also intends to maintain a listing of stack/point/segment combinations that represent DG units both statewide and in the Northern Virginia area. The emissions profile created from base year (assumed to be 2007) operati ons data will be applied to all pollutant emissions for each unit identified as a DG unit . This listing will also be helpful when applying a NO X 

## control strategy reduction factor. At least one regional office, the Northern Regional Office ( NRO ) , has a detailed listing of registration numbers and units that are or may be distributed generation units. Additionally, EIA data can be used to identify other units. A nalysis of the EIA data for Virginia units has already been performed to ensure that these units are in the V irginia database. CEDS data regarding hours of operation w ere examined in creating the listing in Table 5 . If a unit ’ s hours of operation as listed in CEDs indicated significantly more operational time than would normally be expected by a distributed generation unit, then that unit was remove d from the listing and will not have the distributed generation profile applied in the 2007 base year regional air quality modeling. Figure 1 below shows the locations of these facilities in the Commonwealth.

## 3. Inventory Review: After a listing of potential DG units was created from EIA and regional office input, the 2007 inventory data for all line items were examined and modified as follows: 3. a. Stack Parameters: Stack data for each stack/po int/segment combination were examined to ensure all necessary modeling parameters exist in the database. A point to note is that many IC engines have horizontal stacks and are equipped with some type of sound muffler. Newer units are more often equipped with vertical stacks. For any stack with an obstructed or non - vertical discharge, the exit gas velocity was changed to 0.001 meters/second (0.003 feet/second). For any stack with no stack data due to the stack being labeled as a fugitive emissions sourc e, the height was changed to 15 feet, the diameter was changed to 1.5 feet, the stack temperature was changed to 900 deg F, the stack configuration was changed to a horizontal discharge, and the exit gas velocity was changed to 0.001 meters/second (0.003 feet/second). A few line items did not have latitude and/or longitude data in the correct decimal format. That information was provided from the UTM converter in CEDS.

Page 4 3.b. Non DG operations: Care was taken to remove from the inventory any engines that may be associated with rock processing plants, asphalt plants, or concrete plants. Also, for facilities that were beneath the 10 tons/year cut off and therefore would not normally be included in the 2007 po int source modeling inventory, any line item in that facility’s inventory that was not related to DG operations was deleted and not added to the 2007 point source modeling inventory. 3.c. Non - operational units: For facilities that were beneath the 10 tons/year threshold and therefore not normally inc luded in the 2007 point source modeling inventory, any distributed generator line item with zero emissions was deleted, even if the line item was considered to be planned for operations. Also deleted from the DG inventory was any line item identified as D G and normally in the 2007 point source modeling inventory but that had zero 2007 emissions. 3.d. Emissions inventory: The 2007 CEDS data only included the filterable portion of the particulate emissions from all units. Additionally, some DG units were coded with both PM 10 

## and PM 2.5 

## , and some were coded with either PM 10 

## or PM 2.5 

## . Some were also coded without any mention of PM 10 

## and PM 2.5 

## . The main thrust of this inventory and modeling exercise is to examine DG units’ effect on ozone concentrations. However, since augmented data to help fill in data gaps were available from MACTEC, the augmented data containing filterable and condensable PM emissions fractions as well as data for PM 10 

## and PM 2.5 

## were included in the final DG inventory. 4
. Creation of an emissions profile: VDEQ use d 2007 operations data obtained from Dominion V irginia Power for the ir demand response program s (including the Manassas VMEA program) as well as data obtained from AOL , NOVEC, and duP ont Fabros to create a 2007 profile for wh en these units generally operated. To simplify the creation of the profile, units are assumed to be operating at full capacity whenever they are being used. The generic profile will be applied to all units identified as DG units in the 2007 emissions inv entory for Virginia. 5
. Application of the emissions profile: VDEQ develop ed a generic profile in a SMOKE readable format for each pollutant listed in the emissions inventory. Th is profile simulate s a step function, turning on and off the identified ge neration units depending on their operational mode. VDEQ passed on this profile to the emissions inventory contractors and requested that it be included in both base and future inventories for SMOKE modeling

. Figure 2 below graphically presents the appl ication of the chosen profile during May of 2007 on an example unit . Units are assumed to be on or off, and when on, the units are assumed to be operating at the same load and emissions rates.

. Future year control strategies: In future years, control strategies that assume up to 90% - 95% NO X 

## reduction can be applied to the distributed generation units that are not already controlled. 7. Growth Factors: In previous emis sions inventory work, growth factors for these types of units were created using E - GAS, which underestimated the growth of this source sector between 2002 and 2009. One issue for future consideration is the creation of a better estimate of growth between base and future years for this source sector. **Development of the Emissions Profile:** Table 4 below summarizes the information collected from a variety of sources in the distributed generation sector. Dominion provided 2007 data for its stand - by generatio n (SG) program. The program is also referred to as a curtailable service and stand - by generation program. The program requests that facilities reduce load such as shutting down a production line or requests that existing generation be brought on line to peak shave or sell power back to the grid. Dominion also provided 2007 operations data for the VMEA, which is a co - op with the City of Manassas. These units can operate as stand - by generation or peak shavers.

Page 6 The NRO staff provided data gathered durin g the execution of several enforcement actions against distributed generation units. Data from an America On - Line (AOL) data center site, a duPont Fabros (DFT) data center site, and Northern Virginia Electric Cooperative ( NOVEC ) are listed. These facilit ies have large amounts of generation on site, sometimes totaling more than 25 M W of capacity. The purpose of the generation at data centers is to provide back up power to ensure that data center operations maintain a high level of up time, often required in contracts to be better than 99.9% reliable. These facilities also have lucrative contracts to use this generation in a distributed generation program. It should be noted that as a result of the e nforcement actions brought by N RO, many of these units h ave been retrofitted with either open or closed loop SCR to reduce NO X 

## emission by 80% - 9 0%. Table 4 demonstrates that in 2007, a significant amount of overlap existed for days and times when these units were in operation. Also, four days ( grey highlight ed rows) contain two separate time periods when units were called to participate in various programs. To create a generic profile, Table 4 examines two methods for analyzing the data. The first method (option 1) includes every day that any program operat ed according to the known data. For any day that a program operated, the data for the day with the most hours of operation was included in the generic profile. These columns are labeled “Generic Profile, Any Run Day” in Table 1. When including all days for which data exist, the generic profile for 2007 would contain 514 hours of operation over 111 days during the year. Wh en compared to the maximum that any one particular program operated (93 days, and 314 hours) , this methodology tends to overestimate t he amount of time any unit is on line. Howe ver, as shown in the examples below, the results are quite a bit higher than the application of the default profile. The second method (option 2) includes every day that any two programs operated according to the known data. For any day that two prog rams operated, the dat a for the day with the most hours of op e ratio n was included in the generic profile. Thes e columns are lab e led “Generic Profile, Days with Two or More Data Points.” W hen including these paramete rs in the make - up of the generic profile, the profile for 2 0 07 would contain 381 hours and 92 day of operation. This methodology seems to better represent the maximum program times and days although it may still overestimate the number of hours of operati on in the stand - by generation program operated by Dominion . Overestimation of the number of hours results in underestimation of daily and hourly emission rates for NO X 

## . As an example of how each profile may be applied, assu m e a facility has three units, each 2 M W. Two units reported emitting 10 tons of NOx in 2007, each. One unit emitted 5 tons of NOx in 2007. If the default, 365 day, 8760 hrs/year operational profile was assumed, the units would have the following emission rates in the modeling anal ysis:

Page 7 **Table 1: Example Emissions from a Hypothetical DG Facility , using 365 days/year**  **Unit Annual NOx**  **Daily NOx**  Unit 1 10 tons NOx/year 0.027 tons NOx/day Unit 2 10 tons NOx/year 0.027 tons NOx/day Unit 3 5 tons NOx/year 0.014 tons NOx/day Total NOx in 2007 25 tons NOx 0.068 tons NOx/day 

## The calculation is as follows: 10 tons NOx/yr * 1 yr/8 , 760 hrs * 24 hrs/day = 0.027 tons NOx/day Each day and each hour would have exactly the same amount of emissions. If the first generic profile is used (opti on 1) , 514 hours are divided up over 111 days. T he maximum number of ho u rs of operation in any day is 16, which occurs in December. Twelve hours is the maximum for the ozone season and occurs August 8 th 

## from 11:00 to 23:00 . For this ozone season example , 12 hours will be used: **Table 2: Example Emissions from a Hypothetical DG Facility, using 111 days/year**

**Unit Annual NOx**  **Daily Ozone Season NOx**  Unit 1 10 tons NOx/year 0.23 tons NOx/day Unit 2 10 tons NOx/year 0.23 tons NOx/day Unit 3 5 tons NOx/year 0.12 tons NOx/day Total NOx in 2007 25 tons NOx 0.5 8 tons NOx/day 

## 10 tons NOx/yr * 1 yr/514 hr * 12 hours/day = 0.23 tons NOx/day In the model, these hourly and daily emissions for August 8 th 

## would be assigned to 11:00 through 23:00. Each day would v ary, as noted in Table 4. If the second generic profile is used (option 2) , 381 hours will be divided over 92 days. Again, August 8 th 

## provides the summer day with the most hours of operation (12), so this day will be used for comparison:

**Table 3: Examp le Emissions from a Hypothetical DG Facility, using 92 days/year** 

**Unit Annual NOx**  **Daily Ozone Season NOx**  Unit 1 10 tons NOx/year 0.31 tons NOx/day Unit 2 10 tons NOx/year 0.31 tons NOx/day Unit 3 5 tons NOx/year 0.16 tons NOx/day Total NOx in 2007 25 to ns NOx 0.78 tons NOx/day 

## 10 tons NOx/yr * 1 yr/381 hours * 12 hours/day = 0.31 tons NOx/day

Page 8 This methodology is not nearly as accurate a procedure for assigning emissions as is the CAMD emissions data from CEMS. However, at the current time, it may be the best methodology available for better representing the emissions from the distributed generation category in the base year emissions inventory. After review of the data, o ption 2 above was chosen to create the profile for the DG units. This approach omits days from the profile where only one system was running, which reduces the time operated by 19 days
. It spreads the emissions over 381 hours in the year rather than 514 hours. This total hourly value is higher than any of the hourly operations of a ny of the systems as shown in Table 4 so that the estimates on an hourly basis from each system should be conservative, with little overe stimation of hourly emission rates.
