QUARTERLY GAS ISSUES UPDATE

Supply Issues
Wholesale Natural Gas Prices
Skyrocketing crude oil prices have caused a significant increase in wholesale natural gas market
prices. The average projected price at PG&E Citygate over the next twelve months was $8.05 per
MMBtu as of April 5, 2005. Prices have increased approximately 50% since January 2004 and 25%
since January 2005. Figure 1 below provides historical monthly bid week index prices and projected
future natural gas prices at PG&E Citygate.

Supply Acquisition
In June 2000, staff began to implement the “laddered” gas procurement strategy to lock in gas costs
for pool customers (customers not eligible for direct access). The laddering strategy was revised in
January 2004 and presented to the City Council in March 2004 [CMR:167:04].
Approximately 75% of the expected pool load is hedged for the remainder of FY 2004/05 with a
total expected pool cost of $13.7 million. The expected cost for the City’s entire portfolio (pool
customers plus large customers either on the G-3 rate or a contract rate) is $18.4 million.
Approximately 88% of the expected pool load is hedged for FY 2005/06 with an expected cost of
$15.5 million and a cost of $21 million for the entire portfolio. Figure 2 shows the expected pool

Figure 2
Because of the fixed-price purchases, the City’s weighted average cost of gas (WACOG) differs
from the monthly market price. The City’s estimated WACOG for the pool is $5.31 for FY 2004/05,
approximately 17% below the weighted average market price for that same period of approximately
$6.38 per MMBtu. The City’s estimated WACOG for the pool is $5.89 for FY 2005/06, compared
to the current weighted average forward market price of approximately $8.03 per MMBtu, a savings
of approximately 27%. In the months close to the end of the laddering time horizon, the City’s
WACOG is closer to the forward market price since purchases were done more recently and because
a smaller fraction of the total gas needs have been purchased for this period (as shown in Figure 2).
Figure 3 below illustrates the difference between market prices and the City’s estimated WACOG.

Regulatory Issues
Gas Supply Order Instituting Rulemaking (OIR)
Key issues in this proceeding include: gas quality, infrastructure and gas supply adequacy for
generators, at-risk ratemaking, direct connection of independent storage, and some SoCal items.
Staff attended a pre-hearing conference (PHC) where parties discussed how best to address the key
issues.
Gas quality issues are pointed primarily to prospective new liquefied natural gas (LNG) facilities to
be located adjoining the SoCal Gas system. Since no LNG facilities have been proposed for
Northern California, the issue is of consequence to Palo Alto only in a global sense.
The issue of gas supply adequacy for generators were generally agreed to be a subset of the wider gas
supply adequacy issues for the Investor Owned Utilities (IOUs). Direct connection for the
independent storage operators was a matter between PG&E and the two Northern California
independent storage operators (Lodi & Wildgoose) and is better left to resolution by the parties by
themselves.
Palo Alto’s focus is the appropriate pipeline capacity reserve levels to be held by the core and noncore on PG&E’s system and costs associated with such and the provisions to provide access to new
supply by PG&E, including LNG. No other issues are of concern for Palo Alto in this proceeding.

Item 6: Utilities Quarterly Report Update Attachment B: Gas Page 3 of 10
Attachment B – Quarterly Gas Issues Update
PG&E Biennial Cost Allocation Proceeding (BCAP) Application
Palo Alto does not have any outstanding issues in this settlement. Palo Alto will be allocated
$87,000 per year compared to today’s cost of about $74,500 through the Customer Class Charge that
will account for about 9% of Palo Alto’s total transportation payment of $990,000 to PG&E in 2005.
This slight increase reflects PG&E’s cost increase. Staff and Palo Alto’s consultants have checked
PG&E’s cost allocations and it appears that PG&E has properly applied existing CPUC policies to
compute Palo Alto’s rate. The new rates are proposed to be effective July 1, 2005 for a two-year
period.
