MSG Changes

Page 3

MSG Changes - Background

• Units that are used for replacement capacity are considered

as RA capacity only on days they are used

• As a result the RA value may change on a daily basis
• The ISO must make changes to the process of submitting

proxy bids into the ISO markets when an RA resource has failed to submit its own bid or self-schedule

• This has specific consequences for MSG units

Page 4

MSG Changes - Background

• MSG units submit a default RA configuration, corresponding to

the monthly RA value, and a preferred MSG configuration path to get the default MSG RA configuration

• Since RA value can potentially change on a daily basis, the

current single value for the default RA configuration may no longer be sufficient to determine a valid proxy bid

• Additionally, if the default configuration may differ (for a

different RA value) the configuration path to that default configuration may also differ

Page 5

MSG Changes – ISO Proposal

• Instead of one default RA configuration, MSG resources will

submit a table which shows the default configuration for all potential RA amounts using resource data template

• Instead of the SC submitting a default path to the default

configuration – There may now be several default configurations – The ISO will use the information provided by the MSG unit

• n its possible configurations in the Master File to

determine the default configuration. The default configuration will be filled in with the default energy bid up to the RA capacity. Any lower configuration will also be filled with default energy bid up the RA capacity

Proposed tariff changes and Timeline

• Tariff changes the ISO proposes is to eliminate any scattered

references to the term “Default Resource Adequacy Path” and amend section 30.7.3.5 and 27.8.2 to submit a table establishing default configuration and remove default path requirement – Draft ISO proposal

Progress Report

SCP Many to Many Substitutions

• Initial impact analysis complete
• Preliminary technical analysis complete

– Appears to be feasible for an automated solution – Too many complexities for a manual solution – Potential implementation issues might arise when BRS and SRS are formulated

• Next step

– Initiate and prioritize a project to complete this initiative
