QUESTION 20.2:
20.2. With respect to Mr. Lenart’s testimony at pages 13-14 (10-3-2008 version) where
he states:
However, beginning in the second year of the BCAP period,
the base margin portion of the ITBA and NFCA regulatory
accounts should be excluded from the usage rate applied to
Option #1. This is proposed because over and undercollected revenues related to base margin are included in
the ITBA and NFCA regulatory accounts, and these
accounts are part of the non-base margin costs included in
the usage rate. By definition, revenues collected through a
reservation charge should not incur any over or undercollection as do revenues collected through a volumetric
rate. Therefore, SDG&E and SoCalGas are proposing to
remove base margin portions of the NFCA and the ITBA
regulatory accounts from the usage rate that is applied to
Option #1.
20.2.1. Starting in Year 2, is SoCalGas proposing to forego collecting the ITBA and
NFCA regulatory accounts entirely from TLS customers?
20.2.2. If the answer to the previous question is “no”, then is SoCalGas proposing to
collect the TLS share of the ITBA and NFCA regulatory account balances
from adjusted Option 1 reservation charges?
20.2.3. If the answer to the previous question is “no”, then how is SoCalGas
proposing to collect the TLS share of the ITBA and NFCA regulatory account
balances starting in Year 2?
20.2.4. Please provide numerical examples based upon Mr. Lenart’s workpapers
that demonstrates each of the processes that are described in the response
to the previous two questions.
RESPONSE 20.2.1:
No
RESPONSE 20.2.2:
No

RESPONSE 20.2.3:
SoCalGas will collect the TLS share of the ITBA and NFCA regulatory account balances
starting in year 2 through the usage charge applied to TLS customers. The usage
charge applied to reservation customers will not contain any base margin costs.
There are two types of TLS customers; and, therefore, two types of usage charges.
Those that select option #1 are reservation customers. Those that select option #2 are
volumetric rate customers. Customers selecting option #1 will pay a reservation charge,
whether they transport gas or not. By definition these customers will not incur an over or
under-collection.
Customers selecting option #2 will pay a volumetric rate only on the amount they
transport. This group of customers will incur an over-collection or under-collection
whenever their actual volumes are different than forecasted volumes.
Therefore, starting in year 2, the base margin portion of ITBA and NFCA should not be
charged to TLS customers that select option #1, the reservation customers. TLS
customers that select option #2, volumetric rate, will pay their portion of the ITBA and
NFCA as do other noncore customers that pay a volumetric rate.
TLS customers may also select a mix of both options 1 and 2.
RESPONSE 20.2.4:
The usage rate for year 1 is calculated as $0.01292/therm. This was derived at as the
total non-base margin items allocated to TLS customers divided by the average year
throughput of TLS customers. [$45,756 / 3,540,988 Mth = $0.01292/th]
The TLS customers that choose the reservation rate (option #1) will not incur any
over/under-collections. Therefore, after the first year and, assuming that all other
customers operate at the same usage levels and the regulatory accounts remain the
same, the NFCA and ITBA accounts will be lower due to the TLS-reservation customers
not causing any over/under-collection.
Therefore, starting in Year 2, there will be two usage charges. One for TLS-reservation
customers (option #1) and another for TLS-volumetric customers (option #2). The
difference will be that the usage rate for TLS-volumetric customers will have an adder to
collect base-margin related over/under-collections in the NFCA and ITBA accounts.
The usage rate for TLS-reservation customers (option #1) will be $0.00998/therm. This
is arrived at by dividing the total non-base margin items that are allocated to all TLS

customers, less the base margin portion of NFCA and ITBA accounts, by the average
year throughput of all TLS customers.
The usage rate for TLS-volumetric customers (option #2) will be $0.01292/therm.
This is arrived at by adding an additional amount to the option #1 usage rate to collect
base-margin related over/under-collections in the NFCA and ITBA accounts. If the
additional amount is $0.00294/th, then the usage rate for TLS-volumetric customers will
be $0.01292/th.

QUESTION 20.3:
20.3. With respect to SoCalGas’ response to SCGC-03, Q.13:
20.3.1. Please provide an answer to Q.3.13.5, which seems to have been omitted
from the response.
20.3.2. Is SoCalGas proposing to collect the rate for load balancing injection fuel
through transportation rates?
20.3.3. If the answer to the previous question is “yes”, please specify which
customer classes would have this injection fuel rate applied to their
transportation rates.
20.3.4. Please provide the information presented in Table 8 for the years 2005 and
2007.
20.3.5. Please provide the workpapers for the calculation of the data used in Table 8
and specify how each figure in the table was developed.
Please provide a breakdown of the net injection column in the daily operations files
available on SoCalGas Envoy for the years 2005, 2006, and 2007. In other words, on a
daily basis the net injection column should be separated into core injections, load
balancing injections, nominated injections to storage, core withdrawals, load balancing
withdrawal, and nominated withdrawals to storage.
RESPONSE 20.3.1:
The System Operator cannot “manage” the fuel used for balancing. That is a function of
how much customers choose to cycle gas by using the flexibility afforded them under
the 10% monthly balancing rules.
RESPONSE 20.3.2:
Yes.
RESPONSE 20.3.3:
All.

RESPONSE 20.3.5:
See source notes for 20.3.4. Daily core data is unavailable to System Operator and
was not used to calculate implied core injections for the year. Instead, monthly billing
data was used to generate an approximation. Starting in April 2009 the Operator can
track core storage nominations on a daily basis just as it does for noncore storage
customers. There is no fuel used in the withdrawal process.
