  5. Metered Market Participant (MMP) IMO Revenue Metering:Roles and Responsibilities Metering Service Provider (MSP) • Collects metering data daily • Processes metering data • Issues trouble calls to MSP • Maintains the metering database • Responds to market participant queries • Provides settlement statements derived from the metering data • Registers meters • Maintains metering installation • Responds to trouble calls and investigates meter errors • Provides edited metering data • Provides correction factors where necessary • Provides a metering installation • Provides metering data to the IMO • Submits physical allocation data for each RWM (if necessary) • Identifies an associated MSP to the IMO

  6. Single Main/Alternate Main/Check Types of Meters • Data may be substituted if main meter fails • Data may come from non-Measurement Canada approved meter • Used only where there is an established correlation with main meter • Must have separate set of instrument transformers (ITs) • Existing single installations must apply for a waiver from the IMO • New RWMs may not be single installations • Must be replaced by main/ alternate installations upon expiry of seal (within 6 years) • Installations consist of two revenue meters to ensure that metering data can be cross-verified • All new RWMs must be main/alternate installations

  7. Single Main/Alternate Main/Check Data Validation • Compares data from an IMO- approved meter and another source - both record the same data with a correlation factor applied • Use of check data for settlement is permitted only when main meter has failed, & under controlled conditions specified by Measurement Canada • Validation relies on historical meter data for comparison purposes • MSP specifies criteria for validation tests at time of registration • Compares data from 2 IMO-approved meters (main & alternate) • Data from alternate meter is of revenue quality & can be substituted for main meter data without legal implications

  8. yes • Substitution no Point-to-Point yes no Data Estimation Methods Is validated data from alternate orcheck meter available? Is missing data for one hour or less? Historical

M1 Actual Meter Point Connection Circuit < 50kV Facility Distribution System ECP (EmbeddedConnection Point ) Actual Meter Point Embedded Market Participant

  11. To Other LDC Loads Loss Adjustments Example Typical LDC Connection, with Embedded Meter Point: Transmission System Defined Meter Point, Delivery Pt 1,Delivery Pt 2. M1 Actual Meter Point Connection Circuit < 50kV Facility ECP (EmbeddedConnection Point ) Distribution System M2 Embedded Market Participant Actual Meter Point

  12. SSL1 To Other LDC Loads Loss Adjustments Example Typical LDC Connection, with Embedded Meter Point: Transmission System SITE-SPECIFIC LOSSES DMP, Delivery Pt 1,Delivery Pt 2 . M1 Actual Meter Point Connection Circuit < 50kV Facility ECP (EmbeddedConnection Point ) Distribution SSL2 System M2 Embedded Market Participant Actual Meter Point

  13. SSL1 DLF To Other LDC Loads SSL2 Loss Adjustments Example Typical LDC Connection, with Embedded Meter Point: Transmission System DMP, Delivery Pt 1,Delivery Pt 2. DISTRIBUTION LOSS M1 Actual Meter Point Connection Circuit < 50kV Facility ECP (EmbeddedConnection Point ) Distribution System M2 Embedded Market Participant Actual Meter Point

  14. ADJUSTMENTS: SSL1 Embedded MP = (M2 + MEC2 + SSL2) x DLF To Other LDC Loads Loss Adjustments Example Typical LDC Connection, with Embedded Meter Point: Transmission System DMP, Delivery Pt 1,Delivery Pt 2. M1 DLF Actual Meter Point Connection Circuit < 50kV Facility SSL2 ECP (EmbeddedConnection Point ) Distribution System M2 Embedded Market Participant Actual Meter Point

  15. SSL1 TOTALIZATION: 1. LDC = (M1 + MEC1 + SSL1) - (M2 + MEC2 + SSL2) x DLF 2. Embedded MP = (M2 + MEC2 + SSL2) x DLF To Other LDC Loads Loss Adjustments Example Typical LDC Connection, with Embedded Meter Point: Transmission System ADJUSTMENTS: Embedded MP = (M2 + MEC2 + SSL2) x DLF LDC = (M1 + MEC 1 +SSL1) DMP, Delivery Pt1,Delivery Pt 2. M1 DLF Actual Meter Point Connection Circuit < 50kV Facility SSL2 ECP (EmbeddedConnection Point ) Distribution System M2 Embedded Market Participant Actual Meter Point

  16. Totalization Example Typical LDC Connection, with Embedded Meter Point: SSL1 = 0.36 MW Delivery Point 1 (SPRUCE) = 69.243 MWDelivery Point 2 (PINECO) = 51.357 MW DLF = 1.02 M1 Actual Meter Point M1 =120 MW;MEC1 = 0.24 MW ECP (EmbeddedConnectionPoint) SSL2=.2MW M2 M2 = 50 MW;MEC2 = 0.15 MW Actual Meter Point Embedded Market Participant

  17. Application of PAD - Example • Allows sharing of metered data • E.g., customers of an Aggregator need not have RWMs • Aggregator negotiates with the LDC • LDC submits PAD to IMO • IMO bills: • Aggregator for negotiated amount • LDC for metered amount less the negotiated amount M1 M2 Transmission System x x x x x x x x x x x x Distribution Aggregator x System x x
