 New Billing Determinants:
 MSBDINFO_CQ – Mismatched InterQSE Schedule
Delivered Counter QSE Information
 MSBRINFO_CQ – Mismatched InterQSE Schedule
Received Counter QSE Information
 Mismatches occur when:




Different amounts in the same zone
No corresponding counter-party schedule
Different zones (either same amount or different)
Energy schedules submitted by QSEs with ERCOT as a
resource (not a true mismatch)

Mismatch Quantity Calculation
 Post Implementation: the mismatch quantities
(MSDQTY and MSRQTY) will be the sum of the new
billing determinant records (MSBDINFO_CQ and
MSBRINFO_CQ) containing positive values.
 Using the previous examples, the following QTY
records will be created:
 MSDQTY_Z05_QSEA,CH# 27
 MSRQTY_N05_QSED,CH# 20
 MSRQTY_Z05_QSEA,CH# 5

Texas SET 2.1 code freeze (scheduled to end
December 2, 2005) affecting resources, testing
environments, deployment schedule.
 Phase Two: mid to late 2nd Quarter 2006 -complexity: creating an extract that retrieves data
from the Siebel source and the Lodestar source;
need to explore design options.
50129 Revision to Balancing Energy
 Background:
 PRR 569 modifies the settlement calculations so that the
payment to the QSE will be based on the bid premium
supplied by the QSE adjusted for the difference in the
Fuel Index for the day before the Operating Day and the
Fuel Index for the day the service was provided. This
results in a normalized FIP being used for Local Balancing
Energy payments. This includes both Aggregate and
non-Aggregate resources that are Gas Fired.
 Estimated deployment date: December, 2005

This Revision to Balancing Energy from a specific Resource project
will alter the Price portions of the Amount formulas for:




LBEUP
LBEDN
LBEUPAGG
LBEDNAGG


FIPd-1 stands for the FIP price for the previous Trade Day.
FIPd stands for the FIP price for the current Trade Day.
These changes affect both Generators (gas-fired units only) and
LaaRs.
The formula change deals with the Bid Premium sections of the
price formula.
The Fuel Index Price (FIP) is not used in the current LBE formulas.
FIP is used in the OOME formulas. The LBE formulas use MCPER
and Bid Premiums since they pay the Resource as bid. This will
change with this project and thus the FIP will be used within the
LBE formulas.
The reason for this change is that Market Participants will be
submitting bids for tomorrow based on the FIP that is posted for the
current day. This project will normalize the FIP so that the
Resource is accurately paid for the service they are called to
provide.
FIPd-1 & FIPd:
50129: LBE Formula Changes Summaries




LBEUP: The Price portion of the Amount formula takes the Maximum of the
OOMLEUPBP and MCPER and then subtracts the MCPER. The new formula
will take the (OOMLEUPBP/FIPd-1)*FIPd.

The same logic applies to LaaRs.

This logic does not apply to LaaRs as they are not eligible for LBEDN payment.
LBEDN: The Price portion of the Amount formula takes the Maximum of the
0 or the MCPER - OOMLEDNBP. The new formula will take the
(OOMLEDNBP/FIPd-1)*FIPd.
LBEUPAGG: The Price portion of the Amount formula takes the
OOMLEUPBPAGG – MCPER. The OOMLEUPBPAGG is calculated by taking the
MINIMUM Bid Premium of all the units that make up the aggregated site.
Remember that the logic for this is changing such that the OOMLEUPBP
portion will now be (OOMLEUPBP/FIPd-1)*FIPd and this is how the
LBEUPAGG formula is affected. The OOMLEUPBPAGG will still take the
Minimum Bid Premium of all the units that make up the aggregated site but
now how the individual units calculate that premium will change under the
new formula.
LBEDNAGG: The Price portion of the Amount formula takes the Maximum of
0 and the MCPER - OOMLEDNBPAGG. The OOMLEDNBPAGG is calculated by
taking the MAXIMUM Bid Premium of all the units that make up the
aggregated site. Remember that the logic for this is changing such that the
OOMLEDNBP portion will now be (OOMLEDNBP/FIPd-1)*FIPd and this is how
the LBEDNAGG formula is affected. The OOMLEDNBPAGG will still take the
Maximum Bid Premium of all the units that make up the aggregated site but
now how the individual units calculate that premium will change under the
new formula.
