1 Market Performance and Planning Forum June 5, 2013
2 Objective: Enable dialogue on implementation planning and market performance issues Review key market performance topics Share updates to release plans, resulting from stakeholders inputs Provide information on specific initiatives to support Market Participants in budget and resource planning Focus on implementation planning; not on policy Clarify implementation timelines Discuss external impacts of implementation plans Launch joint implementation planning process Slide 2

14 Summer outlook Process is in place to align DA and RT conditions to mitigate price differentials and offset costs. Transmission enhancements are expected to reduce real-time congestion. TRM in place since late summer last year has proven to be beneficial in reducing real-time congestion related to loop flow. Slide 14
15 Exceptional dispatch reporting OASIS reports EDE or exceptional dispatch energy. EDE is the out of sequence or uneconomic energy resulted from exceptional dispatch which is the settled exceptional dispatch amount. Monthly report and MPPF include minimum load energy and EDE. FERC report on exceptional dispatch provides the following: The total volume column: total MWh dispatch quantity dispatched. The ED Volume MWh (MWh INC/DEC) column shows the incremental or the decremental portion of the real-time exceptional dispatch MWh. The MW column shows the range of exceptional dispatch instruction in MW (or the go to MW). Slide 15
16 Circular schedules Implemented circular schedule on 2/1/2013. Identifies circular schedules within the same SC, compares import and export prices and neutralizes the profit if the import price is higher than export price unless exempted. In February, 20 instances of circular schedules detected. No claw back. In March, out of 620 instances detected, only 2 instances of circular schedule profits were neutralized. Slide 16

32 GHG Update Amelia Blanke Market Monitoring Analyst, Department of Market Monitoring Slide 32
33 Greenhouse gas update Greenhouse gas costs were included as part of resource commitment costs, default energy bids and generated bids starting in January These costs were added as part of the commitment cost refinement process in The ISO greenhouse gas index price uses an average of two indices and primarily has ranged from $14 - $16/mtCO 2 e in the first quarter. Most bids for units subject to greenhouse gas increased by less than $10/MWh, which is in line with emissions rates and allowance prices. Wholesale energy prices increased by $ $6.21/MWh in the first quarter due to GHG costs (statistically estimated). Imports increased 10 percent compared to the same period last year, but the mix of importers has changed. Further detail can be found in the Department of Market Monitoring s Q Report on Market Issues and Performance: Page 33

75 RIMPR Phase 1 and BCR Mitigation continued Expected Energy Algorithm Residual: To detect, Ramping from more than one hour before or after; Ramping due to Pmin re-rate; Ramping due to Exceptional Dispatch Optimal Energy: To detect, Ramping due to Pmin re-rate; Ramping due to Exceptional Dispatch; ; Page 75
76 RIMPR Phase 1 and BCR Mitigation continued How to address the ramping energy due to the exceptional dispatch (BRQ0025) A binding exceptional dispatch instruction will be extended forward/backward with the ramping direction; Once it is extended, the exceptional dispatch energy is calculated in current method for extended intervals; As such, previously classified OE or RIE could be changed to EDE Page 76
77 RIMPR Phase 1 and BCR Mitigation continued How to address the ramping energy due to the Pmin re-rate (BRQ0026, BRQ0027) A Pmin re-rate will be extended forward/backward with the ramping direction; Once it is extended, the de-rate energy is calculated in current method for extended intervals; As such, previously classified OE or RIE could be changed to SLIC energy and hence settle as LMP Page 77
78 RIMPR Phase 1 and BCR Mitigation continued How to address the proper reference price used in RIE (BRQ0024) Reference hour will include the forward terminating time going beyond hourly boundaries; Done by looking at the ramping direction, economic level and exceptional dispatch MW; As such, the reference price can be a bid price from a trading hour a few hours before or after.
