1. Interim Fuel Factor Adjustment and Surcharge for Under-Recoveries
Today we will be discussing the recent fuel factor increase and fuel surcharge request that TXU Electric filed with the PUC on August 7, With the recent increases in natural gas prices and oil prices, combined with reduced domestic production and other factors, fuel prices have increased nearly 100% since January. We will explain why we are filing and how it effects you and your business.

2. Fuel Factor Defined
A component of your electric rate that covers the cost of fuel required to generate electricity
Adopted by the Public Utility Commission of Texas in consideration of fuel price fluctuation
Considers future price trends of all fuels as a factor and, in essence, creates average price
Fuel Component can represent between % of a typical commercial & industrial customers’ bill
What is a “Fuel Factor”?
In order to generate electricity, power plants must purchase natural gas or other fuels for use in the production process. The cost of that fuel is included as a part of your electric rate. This fuel cost is a “pass through” amount that generates no profit for TXU. However, it is subject to market prices and fluctuates often.
Prior to 1986, customers were subject to monthly rate increases due to the constantly changing price of natural gas on the open market. In an effort to alleviate those frequent rate changes, the Public Utility Regulatory Act established the Fuel Factor process.
The Public Utility Commission of Texas adopted the process in consideration of fuel price fluctuations.
The fuel factor is a component of your electric rate that takes the price fluctuation into account and, in essence, creates an average price that incorporates historical energy costs.

3. Important Points
Fuel cost is based on the actual cost of fuel, without margin or profit to TXU Electric
TXU mitigates the impact of fuel costs through production of nuclear power and lignite mining
Fuel cost volatility is primarily driven by the cost of natural gas

9. Required by Public Utility Commission
The PUC’s Substantive Rules require a utility to request a surcharge or a refund when the utility has materially under collected or over collected its fuel costs and projects that it will continue to be in that position
The PUC allows petitions to be submitted twice per year.
TXU Electric has two opportunities for filing -- august and February.

10. Maintaining Balance: Refund or Surcharge?
Customer Overpayment for Fuel = Utility will refund to customers with interest
Customer Underpayment for Fuel = Utility requests surcharge to recover cost of fuel and interest
Utilizing a Fuel Factor creates two scenarios:

12. Fuel Factor & Surcharge Filing
August 4, 2000:
TXU Electric filed with the Public Utility Commission of Texas a request to increase the fuel component included in your electric rates in order to recover increased costs of gas.
The August 7 filing requests the authority to increase TXU Electric’s Fuel Factor and institute an interim Fuel Surcharge to assist in recovering costs associated with the increase in generating fuel costs. The formal application was submitted on August 7 and represents the first such request since 1993.

14. Filing in Two Parts Requested Fuel Factor increase
Based on increased cost of commodity natural gas
Requested Six Month Fuel Surcharge
Needed to recover under collection for fuel costs incurred through June 2000
The filing actually contains two important pieces.
First TXU Electric is requesting an increase in the fuel factor designed to help recover anticipated costs associated with the current increase in the price of commodity natural gas, as well as projected increases and sustained high prices for the near future. This filing is specifically in regard to natural gas costs as they effect TXU Generation most often.
Secondly, TXU Electric is also requesting a 6 month fuel surcharge to help recover under collected cost from the past six months. With the rise in natural gas prices, the amount collected from customers was not sufficient to cover the cost of purchasing generating fuels. The surcharge will assist TXU Electric in recovering those short falls.

17. Other Utility Filings
TXU Electric’s Fuel Factor Adjustment Request is among the lowest in the state
TXU Electric is one of the last public utility to file for the increase based on natural gas prices
* Reliant surcharge moved from $69M, 9 mo to $278M, 16 mo

18. Relationship to Senate Bill 7
Electric Rates frozen through January 1, 2002.
AND,
SB7 allows revision of the fuel factor and surcharge requests due to fuel price changes
Legislature and PUC recognize the volatility of fuel costs
Small Commercial and Residential customers will still receive the 6% “Price to Beat” rate reduction on Jan. 1, 2002
Price to Beat” discount includes fuel factor and surcharge as part of rate
“Price to Beat” is discount off customers current rate at start date of competition - 01/01/02

19. Preparing for Electric Price Volatility
Deregulated electrical prices have been significantly more volatile than those of natural gas
Creates potential for significant financial risk in the future
Understanding one’s load profile and how it may be modified will help mitigate this risk
“Konnections” or similar products allow you to capture your load profile for understanding and future pricing
