Staff requests the following:
QUE$TION NO. 1.1
Given the “significant uncertainties related to draft and final regulations issued by the United States Environmental Protection Agency (EPA) governing air, water and solid waste” (IRP, page 4):
a. Please explain why the Company’s only options for increasing generation is to purchase another coal fired generation plant?
h. Has the Company considered the risks and future costs associated with the significant uncertainties alluded to in the Executive Summary of the IRP?
c. Please provide, for the worst-case scenario, the additional costs that would be required to retrofit a supercritical, coal-fired plant equipped to mitigate the minimal EPA current (2016) requirements for future full load operation?
RESPONSE:
a. It is not the only option. Section 7 of the IRP lists and discusses many options for increasing generation and Section 7.5, page 57, of the IRP, specifically lists the lowest cost solutions which is existing coal.
b. Those risks were considered as described in Section 6 of the IRP.
c. The costs, if any, have not been developed for these potential regulations, which remain under litigation, and whose rules and requirements have yet to be defined in the state implementation plans.
Y
UESTION NO. 1.2
Provided that the load forecasting chart on page 6 of the IRP is accurate, please provide substantive data supporting how an existing coal-fired unit can provide the required generation for a deficit in generation (starting sometime in 2016) when each of the five coal-fired units currently in the generating fleet will require a substantial outage to preserve the output of those plants by retrofitting them with co-fired natural gas burners?
a. How can the Company remain in compliance with PJM requirements when at any given outage to retrofit a generating unit with co-fired natural gas burners, generation will he down by at least 546 MW?
SPONSE:
Plant outages are scheduled and approved by PJM to assure reliability is maintained. Efforts to convert for co-firing would likely be done on a unit hy unit basis which minimizes the generation that is unavailable. Additionally, these outages would he scheduled, to the extent possible, for periods during the spring and fall where usage is lowest.
a. A retrofit would be scheduled for a planned outage, usually in the spring or fait, and would be approved by PJM. Planned outages that are approved by PJM assure a plant operator remains in compliance with their requirements. There is no non- compliance with PJM requirements if a unit is not running during a planned outage for retrofits or any other maintenance or capital project.
Y
Regarding the “seasonal peak demand models” used in determining the energy sales and peak demand forecasts for the total connected and retail load (IRP, page 14):
a. What statistical model(s) idare being used for this forecast?
b. Please provide independent, documented studies indicating the accuracy of the projected outcomes of the identified model(s).
c. Do other electric utilities utilize the identified model(s) for projecting energy sales and peak demand forecasts?
RESPONSE:
a. FirstEnergy uses Itron’s MetrixND software for its statistical models for its residential, commercial and industrial customers and energy sales, and its peak demand forecasts for total connected and retail load. The model setups were done in conjunction with ITRON’s forecasting group in 2007.
Jurisdictional peak demands are forecasted using monthly regression models. The monthly peak forecasts are developed by constructing end-use appliance and equipment stock estimates from the energy models to capture end-use and class load diversity on peak demand. The regression models include both temperature sensitive (heating and cooling) and temperature insensitive (base) components as variables to capture variation in growth rates from these determinants of load. Linking the peak demand regression models to the monthly energy sales models through end-use stock estimates helps to ensure that changes in economics along with equipment saturation and efficiency levels from the energy sales models flow through to the peak forecasts.
The temperature-insensitive (base) component variable captures the impact of long- term load diversity since differences in end-use growth and customer load growth across classes impact the level and timing of peak demand.
The temperature sensitive component variables (heating and cooling) capture temperature sensitivity (megawatts per degree-day) in the respective seasons. Peak loads are driven by hot days or a series of hot days in summer and cold days in winter. It is impossible to predict exactly when these patterns will occur, but they do occur every year. In some years, the high and low temperatures are more extreme than in other years. In some years, the extremes occur on weekends, and do not produce peak energy use. For these reasons, the forecasted peak demands are based on an assumption of “normal” peak-setting temperatures, computed in terms of degree days. Future peak-setting temperatures are expected to occur such that 50% of
the values will be higher than normal and 50% will be lower. The average peak- setting conditions are the average over a historical interval.
h. In 2015, ltron conducted its “2015 Forecast Accuracy: Benchmarking Survey and Energy Trends”, which is provided as Confidential Exhibit 1.3a. FirstEnergy was one of the utilities that participated in the study.
c. Yes. Other electric utilities in the US and Canada use energy sales and peak demand forecast models similar to those used by FirstEnergy. PJM also began using Itron’s models for its most recent forecast published in January 201 6. Also, FirstEnergy staff periodically attend Itron-sponsored wehinars, training, and user group meetings, in order to network with other electric utilities and ISOs, and to keep up-to-date on current forecasting methodologies used across the US and Canada.
Regarding the “industrial sales” models used in determining the energy sales and peak demand forecasts for the major North American Industry Classification System (NAICS) (IRP, page 14):
a. What statistical model(s) islare being used for this forecast?
b. Please provide independent, documented studies indicating the accuracy of the projected outcomes of the identified model(s).
c. Do other electric utilities utilize the identified model(s) for projecting energy sales and peak demand forecasts?
a. Using Itron’s MetrixND software, the industrial sales are forecasted using multiple monthly econometric regression models. The industrial NAICS sector sales models forecast the electricity consumption by each of the major manufacturing groups; these groupings have been developed in order to reflect the most significant primary customer segments. For Monongahela Power, the major industrial groupings are “Coal Mining”, “Lumber and Wood Products”, “Chemicals”, “Glass”, “Primary Metals”, “Fabricated Metals, Machinery and Equipment”, and “Other Manufacturing”. For Potomac Ellison, the major industrial groupings are “Paper”, “Rubber & Plastics”, “Stone, Clay & Glass”, “Non-electrical Machinery, Electrical Machinery, and Transportation Equipment”, and “Other Manufacturing”. Each of the major manufacturing groups is modeled separately, while the smaller NAICS sectors are grouped together in an “Other Manufacturing” category.
In the industrial models, energy sales for each manufacturing group are forecasted using a separate, single econometric regression equation. The general specification for the econometric equations for each industrial sector is the same, although the final equations may differ because of industry-specific characteristics. Since electricity is primarily a factor input to production, its use is heavily tied to the level of production activity. Production appears as the main economic driver of electricity consumption in all the industrial model equations. The models typically use county or state-level NAICS specific gross-product as the main economic exogenous drivers. Moody’s Economy.com provides the economic series that are used as inputs to the energy sales regression models.
b. Please see response to 1.3(b). c. Please see response to 1.3(c).
Y
Regarding forecasted annual weather normalized peak growth rate (IRP, page 15):
a. In layman’s terms, please explain how “growth in the natural gas sector” primarily influences the “actual annual weather normalized peak growth rate”.
b. Please provide the supportive data and calculation in an Excel spreadsheet indicating that the actual annual weather normalized peak growth rate from 2010 through 2014 is 3.1% per year.
c. Please provide the supportive data and calculations in an Excel spreadsheet indicating that the actual annual weather normalized peak growth rate from 2015 through 2020 is 2.2% per year.
d. What is the estimated error in the model used in projecting the annual weather normalized peak growth rate (f or - of a YO)?
e. Please expand Figure 4 - Mon Power’s Historical Loads (IRP, page 16) to include years starting in 2005 through 2015. The accompanying data table shall be submitted in Excel format and in printed hardcopy.
RESPONSE:
a. The Marcellus Shale gas boom in FirstEnergy’s region has resulted in the drilling of wells, the construction of gas processing facilities and the installation of other associated equipment, especially pipelines which rely on electric compressor stations to transport gas. Accompanying this new infrastructure is an increased demand for electricity. Before it is used by consumers, the natural gas extracted from underground deposits must be processed. Gas processing plants are midstream facilities that “clean” raw natural gas by separating it into dry and liquid components to produce “pipeline quality” dry natural gas. The plants also are used to recover natural gas liquids ( i s . , natural gasoline, liquefied petroleum) and sometimes other substances, such as sulfur. These refinement and separation processes typically require large amounts of electricity.
Prior to the development of the shale natural gas industry in its West Virginia territory, FirstEnergy’s West Virginia territory experienced slower growth historically, in both MWh sales and peak demand,. This can be seen when comparing growth in the WV industrial MWh sales, the total WV weather normalized MWh sales, and weather normalized peak MW demands before and after 201 3. Prior to 2013, between 2006 and 2012, the West Virginia territory experienced -1.1% overall average annual decline in industrial MWh sales, +0.3% growth in total weather
normalized retail MWh sales, and +0.5% growth in weather normalized peak MW demands. Over the past 3 years, between 2012 and 2015, since the shale-related natural gas industry expanded in the FirstEnergy West Virginia area, the West Virginia territory saw +5.3% overall average annual growth in industrial MWh sales, and +2.4% growth in total weather normalized retail MWh sales. Between 2012 and 2014, the West Virginia area experienced +4.9% growth in weather normalized peak MW demands (2015 normalized winter seasonal peak data is not yet available).
See Exhibit 1.5a which provides supportive data and calculations.
b. The historical actual combined 3-company retail annual weather normalized peak growth rate from 2010 through 2014 is 3.3%. See Exhibit 1.5b which provides the requested supportive data and calculations. The 201 0-2014 previously used to calculate the 3.1% growth rate has been updated to correctly provide retail peak data for the combined West Virginia territory, which includes Monongahela Power-West Virginia, Potomac Edison-West Virginia, and Monongahela Power-West Virginia Power.
c. The forecasted actual combined 3-company retail annual weather normalized peak growth rate from 2015 through 2020 is 2.2%. See Exhibit 1 . 5 ~ which provides the requested supportive data and calculations.
d. Mean Absolute Deviation
MPWV 56.4 MW PEWV 18.6 MW MPWVP 3.1 MW
Mean Absolute ?A Error 3.43% 3.08% 3.87%
It should be noted that the peak models are monthly in frequency. Therefore, the Mean Absolute Deviations (MADS) and Mean Absolute Percent Errors (MAPEs) aren’t solely based on the seasonal summer and winter peak months, but include the errors in the shoulder months as well.
It is possible to compare these MAPEs to the other utilities that participated in Itron’s “201 5 Forecast Accuracy: Benchmarking Survey and Energy Trends” that was discussed and provided in response to 1.3(b). The regression models used by FirstEnergy are built using actual peaks, and actual peak-setting weather variables. Therefore, these MAPE’s compare favorably to the average MAPEs (5.05%) of the responding electric utilities in the ltron study, which is shown in the table below.

e. See Exhibit 1.5d which provides the requested supportive data and calculations for the expanded Figure 4 - Mon Power’s Historical Loads (IRP, page 16), shown below. The 2010-2015 previously provided has been updated to correctly provide retail peak data for the combined West Virginia territory, which includes Monongahela Power- West Virginia, Potomac Edison-West Virginia, and Monongahela Power-West Virginia Power.

Regarding Forecast Loads, please provide the following information (IRP, page 17):
a. Please provide the actual data used in developing Figure 5 - PEAK FORECAST. The data should be provided in Excel format and in printed hardcopy.
b. Provide data supporting the statement that “the summer peak demand [is] generally consistent with PJM’s peak demand”.
RESPONSE:
a. See Exhibit 1.6a which provides the requested supportive data and calculations.
b. A direct comparison for WV is not available since PJM does not forecast state- specific peak demands. Also, FirstEnergy’s Monongaheia Power and Potomac Edison‘s West Virginia territory is part of PJM’s APS zone, but the West Virginia Power portion of Monongahela Power’s territory is part of the AEP zone in PJM. PJM’s winter and summer peak forecast trends and growth rates are generally consistent, but less than, the WV portion of FirstEnergy’s territory.
For its 2016 Load Forecast, PJM solicited input for large changes in load from all the member utilities. FirstEnergy submitted various recommended load changes, including additions for the Monongahela Power territory related to the additional demand expected by the Marcellus Shale growth. Both PJM and Monongahela Power are consistent in that they show growth, although Monongahela Power’s growth is larger than PJM’s overall predicted growth.
Over the next four years (2016-2019), FirstEnergy is projecting average annual growth rates of 3.3% for the summer peaks and 2.9% for the winter peaks for its combined West Virginia territory plus a loss of capacity due to PJM’s capacity performance rules.
It is possible to compare the forecasted longer-term 10-year average annual growth rates of the other utilities that participated in Itron’s “2015 Forecast Accuracy: Benchmarking Survey and Energy Trends” that was discussed and provided in response to 1.3(b), which are shown in the table below.

STAFF’S FIRST REQUEST FOR INFORMATION MONONGAHELA POWER COMPANY and THE POTOMAC EDISON COMPANY
CASE NO. 15-2002-E-P
Regarding Coal Fired Units (IRP, page 30):
a. Please provide the current amount of coal stockpiled at First Energy’s West Virginia coal fired units. This shall include: the facility name and location, the number of tons stockpiled, number of days this stockpile will fuel the plant at full load, the cost to maintain that coal annually, the origin(s) of the stockpiled coal.
b. Please provide the amount of coal stockpiled at First Energy’s West Virginia coal fired units on an annual basis from December 31,2005 through December 31,2015. This shall include: the facility name and location, the number of tons stockpiled, number of days this stockpile will fuel the plant at full load, the cost to maintain that coal annually, the origin(s) of the stockpiled coal.
c. Over the past 10 years, provide when, where (unit location) and why the coal stockpiles were used at all First Energy’s West Virginia coal fired units. Please include the cost savings associated with each incident.
d. Please provide a cost savings analysis study regarding the stockpiling of coal at First Energy’s West Virginia facilities with the data provided in items 1.7.b and c. Tables shall be in both Excel format files and printed.
a. See Confidential Exhibit 1.7a. Additionally, the annual cost to maintain fuel stock is a component of the rate base and the carrying cost is the Companies’ weighted average cost of capital. Also, the Haywood Storage Site includes an estimated cost to lease the off-site storage of $240,000 for 2016.
b. See Confidential Exhibit 1.7b. Additionally, the annual cost to maintain fuel stock is a component of the rate base and the carrying cost is the Companies’ weighted average cost of capital. Also, the Haywood Storage Site included the cost to lease the off-site storage in the amount of $190,000 in 2012, $344,000 in 2013, $522,000 in 2014, and $395,000 in 2015.
c. Coal has always been stored on site at the Harrison and Fort Martin power stations. Additionally, beginning in 2012, coal was and continues to be stored at an additional location (“Haywood Stockpile”) near the Harrison power station.
The coal stored at the plants is used to ensure a consistent and reliable supply of fuel for the generation of electricity. This is necessary to assure adequate coal supplies are available at all times. Both the coal usage and the supply of coal to the plants can
vary so the plants rely on the ability to store excess coal received when deliveries exceed usage or to draw down the storage during times where usage exceeds deliveries. Additionally, the supply chain of coal can, from time to time, be interrupted due to mine shutdowns, problems with delivery systems and routes, weather conditions, unloading issues, etc.
This approach results in not only a consistently available supply of coal, but also allows for lower cost contracts. Coal suppliers would require Mon Power to pay a premium if deliveries had to vary day-to-day, exactly matching the plant usage. Those suppliers would experience higher costs as their mines would experience non- productive down times coupled with other periods of high output. These costs would be passed on to Man Power. Suppliers prefer to ship on a ratable basis ensuring consist operation of their mine(s) which allows the negotiation of better coal prices.
Just-in-time delivery also significantly increases the risk that the plant would experience periods of no available fuel causing generation output to cease. Because of Man Power’s capacity and energy obligations to PJM, this would likely result in charges for failure to perform, some of which could be significant.
d. A cost saving analysis of the stockpiles at the FirstEnergy’s West Virginia facilities has not been performed.

h. Explain how the capacity factor of 67% was determined.
RESPONSE:
a. Same as 1.8a (‘Combined Cycle COE’ tab)
b. The Companies used the capacity factor for existing coal plants for the capacity factor for combined cycle units in order to have an “apples-to- apples” comparison. However, according to recent operating statistics, the capacity factor for a combined cycle is lower. PJM recent data shows that combined cycle units had a capacity factor of 61.5 percent in the first nine months o f 201 5, compared to a capacity factor of 55.4 percent in the first nine months of 2014 (Monitoring Analytics “PJM State o f the Market Report, 43 20 1 5”, page 2 1 2)
