  1. TNT Commercial Operations Working Meeting Betty Day, Kenneth Ragsdale, BJ Flowers April 6&7, 2004

  2. ERCOT strictly prohibits market participants and their employees who are participating in ERCOT activities from using their participation in ERCOT activities as a forum for engaging in practices or communications that violate the antitrust laws. The ERCOT Board has approved guidelines for members of ERCOT Committees, subcommittees and working Groups to be reviewed and followed by each market participant attending ERCOT meetings. If you have not received a copy of these Guidelines, please take one now and review it at this time. Please remember your ongoing obligation to comply with all applicable laws, including the antitrust laws. Antitrust Admonition

  3. Agenda • Review Game plan • Goals • Energy Settlements Background • Energy Settlement Formulas (handouts) • Energy Settlement Examples (handouts)

  4. Game Plan • April 6th & 7th: • Energy Settlement (complete) • AS Settlement (complete) • April 13th: • DaRUC / HaRUC (complete) (examples sent out by 4/9) • CRRs • April 20th: • Review all papers • April 21th & 27th: • Protocols Session

  5. Goal of Next Discussion • Understand Energy Settlement in the Nodal Market • Clarify questions and concerns • Stay focused on ENERGY settlement • Start with REAL TIME ENERGY • Identify the elements necessary for settlement • Ensure there is common understanding of: • Source of the data elements • Units • Time Interval

  6. Deliverables to TNT Examples & Formulas for: • Energy Pay/Charge (ADAM & EHDAM) • Deviation Penalty Pay/Charge • Ancillary Services Pay/Charge (including ESS) • DA/HA RUC Pay/Charge • CRR Pay/Charge (includes “claw” & “40%” for PCRRs) • CRR Balancing Account • BENA • BUL (not sure what changes)

  7. REAL TIME ENERGY Settlement Inputs for Settling Real Time Energy • Metered Energy • Price Calculated for the Load Zones • Price Calculated for the Resource Nodes • Identification of RT energy owner • Identification of the settlement point • ??? Outputs from Settling Real Time Energy • Charges • by Owner • by settlement point • Payments • by Owner • by settlement point

  8. Breaking Down the Complexity of the Electrical Grid Resources serve Specific Nodes Resource Nodes Serve All Load Nodes thru Xmission Network Lode nodes Serve Defined Zones (5 minute LMP observable) Zones are served by assigned Lode Nodes (15 min settlement) Load Node 1 QSE A Doggett Node A Zone B QSE B Cuddy Load Node 2 Node B QSE A Flores Load Node 3 Transmission Network Node D Load Node 4 QSE B Galvin Zone A Node E Load Node 5 QSE B Mickey

  9. Background:Option 1 & 2 • Option 1(pre-EHDAM) • Settle by activity type: • Physical Resource • Physical Load • Bilateral Obligations • Bilateral Resources • Net all activity types by location • Option 2 (pre-EHDAM) • Consider Bilaterals to be “Commitments” • Use the formula (RT – “Commitments”)

  10. Background:LMPs Load Zone A: ($30 x 300 MWh) + ($23.53 x 300 MWh) = $16,059 / 600 MWh = $26.76 Load Zone B: ($21.17 x 300 MWh) = $6,351 / 300 = $21.17 Hub X: ($21.17 + $30 + $23.53) = $74.70 / 3 = $24.90

  11. Background:Texas Nodal Settlements Settlement Calculation Categories • Energy Settlements • Congestion Settlements • Loss Settlements • Operating Reserve or Make Whole Settlements • Ancillary Service Settlements (Reg, Spin, Non-spin, OR, Replacement) • BENA & Other Uplifts • Capacity Settlements (ICAP) • Black Start/RMR • CRR Settlements • Deviation Penalty
