Rogers,
TVA's current bid is $4.75/kw-month, for the term May 1, 2001, through December 31, 2003. Enron could call on units not being dispatched by TVA only if TVA specifically agreed to waive its rights for the specific period. If the AAF is equal to or less than 50% for a month, then the Demand Charge for that month will be zero instead of $2/kw-month. Having the potential of 72 hours of scheduled maintenance per unit each month significantly reduces the availability of the resources and the low guaranteed availability during the non-summer also reduces the value to TVA. Should Enron desire to provide a higher level of availability such as not excluding the maintenance from the availability calculation or different product such as unit capacity with LD energy, then that would increase the value to TVA. A transaction of this duration is subject to TVA Board approval. Please let me know if the bid is acceptable, or if Enron want to offer a product with higher availability.

Nothing below is a representation as to the plant's < operability < < on a going-forward basis. < < < < < (1) Why is the proposed guaranteed availability (75%) so low in the < < < non-summer months? < < < < At the quoted monthly Demand Charge, EPMI feels that the guaranteed < < availability values are competitive. Please note that 75% represents a < < guaranteed availability, and actual availabilty will be targeted at a < much < < higher level. Major maintenance would be completed during the < non-summer < < months. < < < < < < < (2) How do you propose that availability be calculated? < < < < We propose that availability will be calculated using the following < < formula: < < < < AAF = (P*C - D - M)/P*C < < < < where: < < < < AAF = Actual Availability Factor for a given month < < P = the number of peak hours in a given month, where peak hours are HE 7 < - < < 22 Sunday through Saturday (i.e. 7 days a week). < < C = the contracted quantity for that month (in units of MW's). < < D = The number of unit hours declared by EPMI not available in the peak < < hours of that given month times the maximum Contracted Capacity of that < < unit. < < M = The number of MWhs called on by Buyer in the peak hours of that < given < < month, but not delivered by Seller for that month. < < < < Note: Both D and M would exclude the Major Maintenance Outages (see < < below), Scheduled Outages (see below), outages due to Force Majeure, < < Buyer's inability to perform, including but not limited to < < non-availability < < of gas and/or gas transport, and EPMI's inability to operate the plant < due < < to legal, regulatory or permitting restrictions or other reasons beyond < < the < < reasonable control of EPMI. < < < < < < 1. Major Maintenance Outages (MO). The Seller would be allowed 25 days < < per year per unit to conduct major maintenance. MOs would not count < < against the Actual Availability Factor (see calculation below). Seller < < may < < only schedule MO's with at least a 10 day notice and only during the < < months < < of October, November, December, March, and/or April. < < < < 2. Scheduled Outages (SO). The Seller would be allowed 72 hrs per < month < < per unit to conduct scheduled maintenance. SO's would not count against < < the Actual Availability Factor (see calculation below). Seller will < make < < commercially reasonable efforts to schedule SOs during non-peak periods < < (weekends and nights). Seller may only schedule SOs with at least a 24 < < hour notice. < < < < < < Note that the Guaranteed Availability Factor (GAF) would be set at 95% < for < < the summer months, and 75% for the other months. The contracted Full < < Demand Charge (FDC) for any given month would be paid by the Purchaser < to < < the Seller as long as the Actual Availability Factor (AAF) is equal to < or < < greater than the GAF (95% or 75%) for that month. For any month in < which < < AAF falls below the GAF of 95% or 75% depending on the month, the < < Purchaser < < (TVA) would pay the Seller (EPMI) a prorated amount of the FDC using the < < formula below. This prorated amount is known as the Reduced Demand < Charge < < (RDC). Notice that an AAF of 50% or less for any given month would < result < < in a floor Reduced Demand Charge of $2/kw-mo for that month. < < < < ADC = 2 + ((FDC - 2)/(GAF - 50))*(AAF - 50) as long as AAF is equal to < or < < greater than 50% and less than or equal to the GAF (either 95% or 75%) < < < < ADC = $2/kw for months in which AAF is equal to or less than 50% < < < < ADC = FDC for months in which AAF is equal to or greater than the GAF < < < < where: < < ADC = Actual Demand Charge for a given month < < FDC = Full Demand Charge for a given month < < AAF = Actual Availability Factor (as defined below). This number is < given < < as a whole number (e.g. 97% is 97) < < GAF = Guaranteed Availability Factor (95%). < < < < All percentages are rounded to the next highest whole number (e.g. 94.7% < < becomes 95%; 94.4% becomes 94%). < < < < < < < (2) Is the plant "winterized" -- that is can it run in the cold < < weather? < < < < Significant upgrades were made to the plant after the 1999 calendar year < < to < < aid in winterization. In general, however, even fully winterized plants < < tend to be less reliable in extremely cold weather. It would be Buyer's < < responsibility to address natural gas availability and delivery concerns < < throughout the year, including winter months. < < < < < (3) From a manpower standpoint, is the plant available 7x24 for all < < < months -- or are the certain periods of time when the plant is not < < < staffed? < < < < < < The plant is staffed or has members on ready recall 7x24. However, in < < order to have full preparation time, a 3 hour notice is required prior < to < < dispatch. Dispatch outside M-F peak hours (5X16, HE 7 - 22) requires a < 5 < < hour dispatch notice. < < < < < (4) What has been the historic availability of the plant (by month)? < < < < Using the formula above, the Actual Availability Factor (AAF) for the < < plant < < by month for calendar year 2000 is shown below: < < < < Jan 100% < < Feb 99% < < Mar 100% < < Apr 100% < < May 97% < < Jun 97% < < Jul 99% < < Aug 100% < < Sep 100% < < Oct 100% < < Nov 100% < < Dec 100% < < < < Note that approximate average per unit run hours during calendar year < 2000 < < was 215 hours. < < < < < (5) What type of gas transportation has been historically used -- < < < interruptible or firm? < < < < < < Historically EPMI has utilized both firm and interruptible gas < < transportation depending on availability. < < < < < (6) Has the plant ever been unavailable due to the inability of fuel? < < < < Only once since plant construction. This occurred during a run-time < with < < minimal advance notice. In general, fuel availability is the < < responsibility of the Buyer and is more readily available with greater < < advance notice. Note also that the plant was only minimally run during < < the < < most recent winter season due to non-economic dispatch conditions; < < therefore, the availability of gas this past winter was not tested. < EPMI < < is willing to discuss with Buyer making the facility a dual fuel plant, < < subject to permitting restrictions and operational parameters, and < < effected < < at Buyer's expense. < < < < < < < (7) Am I correct in assuming that in the tolling type arrangement, < TVA < < < has exclusive use of the plant --- that is Enron would not have access < < to < < < the output unless TVA specifically waives its rights? < < < < EPMI would not have access to specific units of the plant while those < < units < < were being dispatched by TVA. The plant has six units and four would be < < designated by unit number to TVA for purposes of the tolling agreement. < < EPMI could call on units not being dispatched by TVA. < < < < < < < < < < ---------- < < < From: Rogers.Herndon@enron.com[SMTP:Rogers.Herndon@enron.com] < < < Sent: Thursday, January 04, 2001 2:22 PM < < < To: Goza, Stuart L. < < < Cc: Kevin.M.Presto@enron.com; Elizabeth.Sager@enron.com < < < Subject: RE: EPMI Draft Proposal < < < < < < < < < Stuart, < < < < < < Yes, the 800 hours are annual limits.
