Initial Comment for PRR - 1612

Description: Is it WPTF's understanding that this PRR is related to PRR 1610 which is requiring that VERs in Stage 2 self-schedule. WPTF opposed PRR 1610 thus also opposes this PRR 1612. This PRR basically states that because the CAISO now requires Stage 2 VERs to self-schedule (PRR 1610) that any SC with a VER co-located with another resource and utilizes an ACC will have to be able to ensure the combined output of the two resource does not exceed the ACC. With economic offers, the market could curtail the VER to ensure the combined output does not exceed the ACC. However, this PRR means that the SC will either have to (1) not allow the VER to generate as capable if it will cause the combined output to exceed the ACC, which contradicts the reason behind the CAISO wanting VERs to self-schedule in the first place, or (2) not bid the full amount of the other co-located resource which will likely go against RA bidding obligations. For these reasons, WPTF opposes PRR 1612 and encourages the CAISO to discuss whatever issue its trying to resolve through PRRs 1610 and 1612 in an open stakeholder process so it can be properly vetted by stakeholders and result in any needed FERC filings.

Initial Comment for PRR - 1612

Description: Terra-Gen, LLC - Initial Comments on PRR 1612 Terra-Gen opposes PRR 1612 and concurs with WPTF's initial comments noting the driver for this PRR appears to be PRR 1610. Both of these related PRRs should be considered through formal stakeholder proceedings, not addressed through PRR BPM changes.

Announcement for PRR - 1612

Description: Note: This PRR is not like PRR 1610 and is not requiring self-scheduling by any resources. This is an informational update that resources in an Aggregate Capability Constraint may receive RTD DOTs that exceed the ACC limit if a Stage 2 VER is in the ACC with another resource that participates with energy and Ancillary Services. Resources that are in an ACC have the responsibility to ensure their combined metered output stay within the ACC limit so this is an informational update to be cautious during this short Stage 2 VER timeframe.
