PROCEDURES MANUAL
I. Introduction
This Manual fully describes procedures for participating in the Baltimore Gas and Electric
Company (BGE) Daily Requirements Service (DRS) program. The DRS program allows suppliers to
serve residential and small commercial customers that choose to participate in the Gas Choice program.
The procedures and processes outlined in this Manual are based upon the North American Energy
Standards Board (NAESB) ratified Model Business Practices and adhere to COMAR 20.59 [RM35]
regulations to govern competitive gas supply. The procedures detail the Account Request Process, Daily
Requirement and Parking and Balancing Service.
II. Account Request Process
The Enrollment process for DRS customers is handled via the ACCOUNT REQUEST screen in
DSWeb. The ACCOUNT REQUEST screen allows suppliers to “E” – Enroll, “D” – Drop, “C” – Change
and “X” - Cancel Commercial and Residential DRS customers from the Gas Choice program. Suppliers
must upload their Account Request Transactions using the ACCOUNT_RQST_TO_LDC.xml file. All
Account Request Transactions must be submitted 12 calendar days prior to the start of the month to be
effective the 1st of each respective month.
When customers enroll in the DRS program or switch from one supplier to another supplier, BGE
sends a confirmation enrollment letter to the customer. When a customer drops from the Delivery Service
program and returns to the utility, BGE sends a confirmation termination letter to the customer. Please
note that you as the supplier are still required to provide notice to your customers when your relationship
with them is ending.
A.
Timeline
The following is a description of the Account Request timeline.
A. 1
12 Calendar Days Prior to First of the Month
Suppliers can use the ACCOUNT REQUEST screen to submit “E” – Enroll, “D” –
Drop, “C” – Change and “X” - Cancel transactions daily using the
ACCOUNT_RQST_TO_LDC.xml file, until 5:00 PM EST. BGE will process the
Enrollment Transactions daily and return an ACCOUNT_RESP.xml file by start of
business the next morning detailing the Accept or Reject status of each transaction.
The following are definitions of the Account Request Transactions.




“Enrollment” means the addition of a customer to a supplier’s service.
“Drop” means the removal of a customer from a supplier’s service.
“Change” means the change of a Supplier Group Number
“Cancel” means the reversal of a previous transaction
Please refer to the DRS Enrollment Windows.doc document in the Key Dates
and Lists Category of the Main Library in DSWeb for specific dates associated with the
enrollment windows for the 1st of each month.

PROCEDURES MANUAL
The supplier’s final Account Request confirmation will be communicated via the
ADCQ Detail Report (ADCQDTLmmddyy.prn). The ADCQ Detail Report is available on
the 17th workday of the month prior to the month gas is scheduled to flow. The report will
display the actual Daily Contract Quantity (DCQ) in dekatherms (up to three decimal
places) for all active customers for the next month. All new customers for the first of the
month will be identified with an asterisk (*).
An estimate of all new customer’s monthly DCQ for a projected 12-month period
will be provided through the Monthly Annual DCQ Report (DCQSmmdd.rpt).
A summary of DCQ’s for the next month by Residential and Commercial Supplier
Groups will be provided through the ADCQ Summary Report (ADCQSUMmmddyy.rpt).
B.

transactions can be found in the XML Data Definitions document found in the Fixed File
Layouts Category of the Main Library in DSWeb.
D.
Account Request Transaction Responses and ADCQ Reports
The following listing details the Account Request Transaction Responses and the
ADCQ reports. The Account Request Transactions Responses are generated each day,
while the ADCQ reports are generated on the 17th workday. ADCQ represents the
Average Daily Contract Quantity. The ADCQ is calculated as an average of the last two
year’s usage for the respective month. For example, the ADCQ for June 2012 would be
the average of the usage that was metered in June 2010 and June 2011.
ACCOUNT_RESP
Each day BGE will return an ACCOUNT_RESP.xml and ACCOUNT_RESP.rpt file for
any Account Request Transactions that were uploaded the previous day. These files
will detail whether each Account Request Transaction was Accepted or Rejected.
ADCQ Detail Report
ADCQ Detail Report – This report will display the actual DCQ in dekatherms (up to
three decimal places) for all active customers for the next month. All new customers
will be identified with an asterisk (*). This report is only available in a .prn format.

associated with the ACCOUNT_RQST_TO_LDC transaction.
III. Daily Requirement
Page 6
BALTIMORE GAS AND ELECTRIC COMPANY
DAILY REQUIREMENTS SERVICE (DRS)
PROCEDURES MANUAL
At 12:00 PM each day, BGE will calculate the daily requirement and maximum pool injection and
withdrawal volumes for the next five days. The first of these five days is the gas day that begins at 10:00
AM. The daily requirement for the gas day beginning at 10:00 AM will not change unless there is a
significant difference in the forecasted temperature between 12:00 PM and 7:00 AM forecasted
temperatures. It is important to note that the daily requirement for the next four days will most likely
change as BGE receives estimated temperature updates.
At 9:00 AM, BGE will finalize the daily requirement for the gas day beginning at 10:00 AM. DRS
suppliers will have three options available to fulfill their daily requirement. These three options are listed
below.



Flowing pipeline
BGE allocated pool withdrawal
BGE allocated pool injection
Each DRS supplier has until 2:00 PM to finalize their BGE allocated pool nominations for the
current gas day. At 2:00 PM all storage adjustments will be finalized and the next day’s beginning
inventory will be calculated. All pipeline nominations are subject to the current Gas Industry Standards
Board (GISB) standards.
After the daily requirement is calculated at 12:00 PM and after the storage day has ended at 2:00
PM, the suppliers should refresh their browsers to obtain updated information.
The DRS supplier will be considered to be in balance when they nominate and deliver to BGE the
total daily requirement and nominated injections. If the supplier does not deliver the total daily
requirement and nominated injections, or the supplier with only DRS customers overdelivers to BGE, they
will incur penalties.
A.
Calculation
The following describes the calculation of the Daily Requirement. The calculation of the
Daily Requirement differs based whether the gas day is in a Winter (Oct – May) or Summer (Jun
– Sep) season.
A. 1
Winter Season (Oct – May)
The daily requirement for an individual supplier during the Winter season is
based upon a set of linear regression equations which are generated daily based on the
most recent seven day’s temperature and sample meter consumption per customer data.
A linear regression equation is generated for each of the following customer classes.





D – Residential
DH – Residential with Heat
C – Commercial
CH – Commercial with Heat
CLX – Commercial > 1,500
Two “stabilizer points”, are added to each linear regression equation to eliminate
large swings in the line that is generated. The independent variable “X” is the average
daily temperature and the dependent variable “Y” is average daily consumption per
customer based on sample meter readings.
Page 7
BALTIMORE GAS AND ELECTRIC COMPANY
DAILY REQUIREMENTS SERVICE (DRS)
PROCEDURES MANUAL
The forecasted daily load is generated using the following equation for the Winter
season (Oct – May):
Daily Load = [(slope * forecast temp) + intercept]
* # of customers
* (1/(1-unaccounted for factor))
* (suppliers average class ADCQmonth / system average class ADCQmonth)
The Daily Requirement is the smaller of: the Daily Load for the respective
customer class as calculated above or, the Daily Max for the respective customer class
as calculated below.
Daily Max = [max delivered gas per customer]
* # of customers
* (suppliers average class ADCQJan / system average class DCQJan)
Daily Requirement = MIN(Daily Load, Daily Max)
At the beginning of the heating season BGE determines a maximum delivered
gas per customer by customer class. If the Daily Load as calculated by the algorithm
exceeds the Daily Max, then the suppliers is required to deliver only the Daily Max value.
The remainder will be made up by BGE peak shaving assets, and billed to the supplier as
peak shaving supply. The peak shaving volume is the difference between the supplier’s
daily requirement and daily load.
A. 2
Summer Season (Jun – Sep)
The daily requirement for an individual supplier during the Summer season is
based on the system average class ADCQ for the month, plus the Daily Requirement
Adjustment to reconcile for the annual true-up.
See Annual True-Up section for a detailed explanation of the Daily Requirement
Adjustment.
The forecasted Daily Requirement is generated using the following equation for
the Summer season (Jun - Sep):
Daily Requirement = system average class ADCQ month
* # of customers
* (1/(1-unaccounted for factor))
* (suppliers average class ADCQmonth / system average class ADCQ month)
+ Daily Requirement Adjustment
B.
Penalties
Suppliers are subject to performance-related penalties. A supplier is subject to penalty if
the over-deliver the Daily Requirement, under-deliver the Daily Requirement or under-deliver their
nominated injection volume. Each of these penalties are detailed below.
Over-delivery of the Daily Requirement
Suppliers must deliver the Daily Requirement. A penalty of $5.00 per Dth will be imposed on
every Dth of over-delivered volume. The over-delivered volume subject to penalty will be
Page 8
BALTIMORE GAS AND ELECTRIC COMPANY
DAILY REQUIREMENTS SERVICE (DRS)
PROCEDURES MANUAL
equal to the negative of the Daily Requirement minus the sum of actual pipeline deliveries
and pool withdrawal nominations.
Failure to Deliver Daily Requirement
Suppliers must deliver the Daily Requirement. A $25.00 per Dth penalty will be imposed on
every Dth of under-delivery. In addition, the under-delivered volume must be purchased from
BGE by the supplier. The transaction price shall be 110% of the highest Transco Zone 6
(non-New York) price for the month. The under-delivered volume subject to penalty will be
equal to the Daily Requirement minus the sum of actual pipeline deliveries and pool
withdrawal nominations.
Failure to Deliver Injection
Suppliers must deliver all nominated injection volumes. A $25.00 per Dth penalty will be
imposed on every Dth of under-delivery. In addition, the under-delivered volume must be
purchased from BGE by the supplier. The transaction price shall be 110% of the highest
Transco Zone 6 (non-New York) price for the month. The under-delivered volume subject to
penalty will be equal to the nominated injection volume minus the sum of actual pipeline
deliveries and pool withdrawal nominations.
C.
Annual True-Up
On the 3rd work day of each month, BGE reconciles DRS supplier’s daily requirement
deliveries and actual customer usage for each customer class through a process called the trueup. The supplier’s daily requirement deliveries are determined by summing the daily requirement
and peakshaving volumes by class, for the respective month. The supplier’s actual customer
usage is determined by class, after it is converted from a billing month basis to a calendar month
basis. The customer class true-up is the sum of the supplier’s actual customer usage (adjusted
by city gate volume by dividing by 1 minus the unaccounted for factor) subtracted from the sum of
the supplier’s daily requirement deliveries plus any allocated peakshaving. The customer class
true-ups will be summed and the total will be supplier’s true-up for the month.
The supplier’s true-up will reflect their daily requirement deliveries and actual customer
usage from the calendar month 2 months prior. This is due to the time required to get actual
metered readings. For example: if a customer’s meter is read on June 15 th the reading will have
actual usage from May and June, then on July 15th actual usage will be for June and July.
Therefore we must wait until the August true-up to process total actual usage for the calendar
month of June.
Each supplier’s monthly true-ups will be summed for a 12-month period to determine their
annual true-up. The 12-month period will include the June true-up for April deliveries and usage
through the May true-up for March deliveries and usage. BGE will adjust each supplier’s Daily
Requirement for 122 days (the number of days in June, July, August and September) during the
summer months (Jun – Sep) to reconcile the annual true-up volume. The Daily Requirement
adjustment is calculated by dividing the annual true-up volume by 122. Over the next 122-days,
beginning on June 1, this adjustment would be added to (for an accumulated under-delivery) or
subtracted from (for an accumulated over-delivery) the Daily Requirement calculated for the
respective supplier.
The following are examples of the calculation of the Daily Requirement Adjustment.
Note: Annual true-up volumes are calculated on the 3rd workday of May and includes
deliveries from April of the previous year to March of the current year.

Overdelivery (Daily Requirement = 1,000 Dth)



Supplier overdelivered by 10,500 Dth over the prior 12-month period.
Daily Requirement Adjustment = 10,500 Dth / 122 days = 86 Dth
Adjusted Daily Requirement = 1,000 Dth - 86 Dth = 914 Dth
Underdelivery (Daily Requirement = 1,000 Dth)



Supplier underdelivered by 8,500 Dth over the prior 12-month period.
Daily Requirement Adjustment = -8,500 Dth / 122 days = -70 Dth
Adjusted Daily Requirement = 1,000 Dth + 70 Dth = 1,070 Dth
IV. Parking and Balancing Service
BGE operates a “paper pool” behind its City Gate to provide a Parking and Balancing Service for
Suppliers serving Daily Requirements customers.
A.
Parking Service
Parking is a service which provides for the receipt by BGE of gas quantities delivered by
the Supplier to the Company’s City Gate. This includes the holding of the parked gas by BGE
and the return of the parked gas upon nomination by the Supplier, provided that BGE is not
obligated to return the parked gas on the same day the gas is parked.
B.
Balancing Service
The Supplier’s deliveries to the Company’s City Gate are balanced with the actual
unaccounted-for gas adjusted use of gas by the Daily Requirements customers served by the
Supplier. Any accumulated net difference between the Supplier’s deliveries and customers’
actual use for the 12 months ended March of each year will be divided by 122 days to yield the
adjustment applied to the Supplier’s Daily Requirement for the upcoming four month period June
through September. Any remaining amount due to rounding will be either added to or subtracted
from the Suppliers’ accumulated true-up for the next 12-month period ending March. If a Supplier
ceases participation in the Daily Requirements Service, any accumulated net difference between
the Supplier’s deliveries and customers’ actual use as of the last day of participation is an
adjustment to the amount of gas parked by the Supplier. In the event a Supplier’s accumulated
net difference between the Supplier’s deliveries and customers’ actual use becomes large
enough during the course of the 12 month period that, in BGE’s judgment, it could adversely
impact the Supplier’s summer Daily Requirement, BGE will contact the Supplier to mutually
arrange for an adjustment to the amount of gas parked by the Supplier.
C.
Pool Capacity Allocation
At the beginning of each month, BGE will allocate line pack pool capacity to DRS
suppliers based on their customer population. Average pool capacity allocations for each
Customer Class are shown below.

Inventory Allocation
Once the Pool Capacity Allocation is complete, inventory will be allocated to suppliers
based on their customer population. The inventory allocated for converting customers is based
on the current inventory held for those customers. BGE will maintain operational control of the nonotice aspect for balancing purposes. The DRS supplier has an implied no-notice service in that
the requirement will not change after 9:00 AM regardless of the actual system load.
E.
Injections and Withdrawals
All DRS Suppliers must actively nominate gas into and out of the pool. Pool nominations
can only be made prior to 2:00 PM (EST) for the current day. These nominations will consist of a
blend of 82% East Pool and 18% West Pool during the winter months, and individual pools during
the summer months. DRS Suppliers will be subject to the same restrictions as BGE. These
restrictions for both the winter and summer seasons are listed below.

Note that the withdrawal ratchets are based on the level of inventory.
Pool withdrawal capability decreases late in the season. The first withdrawal
ratchet engages when the inventory level drops to 35%. The minimum inventory
level in January is 38% (see chart below). Therefore, withdrawal ratchets cannot
engage until the month of February.
The injection rights are based on the month of the year. There are daily
limits and monthly limits. Typically the daily limit is the primary restriction. For
Page 11

DAILY REQUIREMENTS SERVICE (DRS)
PROCEDURES MANUAL
example, in the month of January a supplier could inject gas for 26 days at
0.41% of capacity (10.7/.41 = 26.097 days). As shown in the table above, the
most restrictive injection month is November. The least restrictive months for
injections are Jan, Feb, and Mar.

Maximum Withdrawal and Injection Volumes (by month, by day)
Daily maximum withdrawal volumes are a function of inventory. As the
inventory decreases, the daily maximum withdrawal volume will also decrease
based on the daily withdrawal rights as depicted in the Winter Withdrawal Rights
table.
Daily and monthly maximum injection volumes are a function of the daily
and monthly maximum injection rights, depicted in the Winter Injection Rights
table. Monthly maximum injection volumes could further be limited by the
amount of empty pool capacity. For example, if inventory were 95% in
November, then the monthly maximum injection would only be 5% rather than
6.6%, since there cannot be more than 100% inventory.

The East pool allows withdrawals at 50% of full withdrawal capability
from April through September. In October full withdrawals are available from the
East pool. The East pool has daily and monthly injection restrictions in the
summer months also. Maximum injection capability occurs in May, June, July,
and August. Injection capability decreases in September and October as the line
pack pool is filled.
The West pool has one injection ratchet. It engages when inventory
reaches 50% of capacity, and decreases the amount of gas that may be injected
each day.

Maximum Withdrawal and Injection Volumes (by month, by day)
Daily maximum withdrawal volumes from East pool vary from month to
month. Typically the daily maximum withdrawal is 0.68% of capacity, except in
October where the daily maximum withdrawal rises to 1.37% of capacity. This is
depicted in the Summer Withdrawal Rights –East table. There are no withdrawal
rights available from the West pool during the summer months.
Daily and monthly maximum injection volumes into the East pool are a
function of the daily and monthly maximum injection rights, depicted in the
Summer Injection Rights – East table. Monthly maximum injection volumes into
the East pool could further be limited by the amount of empty pool capacity. For
example, if inventory were 95% in August, then the monthly maximum injection
would only be 5% rather than 20%, since there cannot be more than 100%
inventory. Daily maximum injection volumes into the West pool are a function of
inventory level. As the inventory level increases, the daily maximum injection
volume decreases as depicted in the Summer Injection Rights – West table.
F.
Penalties
Suppliers are subject to performance-related penalties. A supplier is subject to penalty if
they do not manage their pool account(s) properly and are above the maximum inventory levels
or below the minimum inventory levels.
Below Minimum Inventory
Suppliers must remain above the Minimum Inventory levels each month. The Below
Minimum Inventory volume subject to penalty will be equal to the minimum inventory volume
minus the inventory volume. During the winter months (Nov – Mar), no penalties will be
assessed. However, all withdrawal rights will be eliminated. During the summer months (Apr
– Oct), supplier’s will be charged $5.00 per Dth on the deficit and also be required to
purchase the deficit from other pool holders.
Page 14
BALTIMORE GAS AND ELECTRIC COMPANY
DAILY REQUIREMENTS SERVICE (DRS)
PROCEDURES MANUAL
Above Maximum Inventory (Failure to Meet Monthly Turns)
Suppliers must remain below the Maximum Inventory levels each month. The Above
Maximum Inventory volume subject to penalty will be equal to the inventory volume minus the
maximum inventory volume. The gas volume subject to penalty will be cashed out and
returned to BGE. The transaction price shall be the lower of 80% of Transco Zone 6 for nonNew York deliveries or 80% of the BGE Pool WACOG.
November 1
Suppliers must meet the (beginning) November 1 inventory range of 90% to 95% of capacity
in both the East and West Pools. The November 1 Inventory volume subject to penalty will
be equal to the minimum inventory volume (90% of capacity) minus the inventory volume.
Supplier’s will be charged $5.00 per Dth on the deficit and also be required to purchase the
deficit from other pool holders.
G.
POOL Screen
The purpose of the Pool Activity screen is to nominate pool injections and withdrawals.
The Pool Activity screen is also used to calculate inventory rights. These rights include the daily
maximum withdrawal and injection volumes, and the monthly maximum withdrawal and injection
volumes (these volumes do not include the shrinkage factor). In addition, the Pool Activity screen
displays the daily DRS requirement, with the date and time the requirement was last updated by
the system. The daily requirement can change up to 9:00 AM for the gas day beginning at 10:00
AM.
