                          DEVELOPING BOOKOUT CAPABILITY

                                  SCOPE OF WORK

The development of a bookout capability will include two major tasks:

1.     development of software to match imports and exports at a scheduling
       point that can be netted out of the import/export schedules passed to the
       ISO

2.     Specifying the changes that will be required to the settlements system to
       correctly charge (pay) the exports (imports) that are netted out and
       those that are not netted out of the schedules passed to the ISO.

Task 1 - Develop application that matches imports and exports:

i.     Extract the initial preferred schedules (IPSs) and schedule adjustment
       bids (SABs) for imports and exports at a scheduling point (SP) that were
       submitted by the PX participants for an hour in the day-ahead (or
       hour-ahead) market from the CORE system.

ii.    Match the imports and exports that indicate their desire to participate
       in the bookout process at a SP to determine the initial preferred net
       import/export at the SP. Match the lowest cost imports with the highest
       value exports as indicated by their SABs using the algorithm described in
       the white paper.

iii.   Map each import or export that indicates its desire to participate in the
       bookout process into an import component and an export component. Develop
       the IPSs and SABs for these newly defined imports and exports according
       to the algorithm defined in the white paper so that the ISO only sees the
       net import or export during its congestion management process.

iv.    Write the modified imports and exports, their IPSs and SABs into the
       ISODAB and CORE systems.

v.     After the ISO performs congestion management, retrieve the modified
       imports and exports and their final schedules (FSs) from the ISODAB.

vi.    Using the inverse of the mapping defined in (iii) to reconstruct the
       final schedules for the imports and exports originally defined by the PX
       participants.

vii.   Match the imports and exports that indicate their desire to participate
       in the bookout process at a SP to determine the final net import/export
       at the SP. Match the lowest cost imports with the highest value exports
       as indicated by their SABs using the algorithm described in the white
       paper. Determine the net import/export at the SP in the final schedule.

viii.  Send information to participants informing them of the imports and
       exports that were matched in the netting process and that bypass the ISO.
       Also inform them of the remaining imports and exports that will be
       delivered to or from the ISO control area. This will be required for NERC
       tagging. ix. Calculate all billable quantities for the net
       imports/exports as well as the imports/exports that were netted out by
       the matching process.

Task   2 - Specify the changes that will be required in the CORE and Settlements
       systems. Implementation to be done by HandEl-OM.
