WMS Report
RUC Task Force
The RUC TF was asked to review alternatives to ERCOT using RUC during
extreme weather events to procure more on-line capacity. There was a lot of
discussion on this topic at the TAC.
After the TAC meeting , Brad Jones sent a memo to TAC Members stating that ERCOT intends to use
the following process:
• Following the clearing of the Day-Ahead Market (DAM) and subsequent Current Operating Plan
(COP) updates for an Operating Day in which ERCOT expects cold weather conditions to create
a reliability reason, ERCOT will review the amount of capacity that is expected to be available.
• If sufficient supplemental capacity is not planned to be On-Line, ERCOT will use the established
Supplemental Ancillary Services Market (SASM) process {Resource Operating Procedure,
Section 5.1} to procure additional Ancillary Services (e.g., Responsive Reserve Service (RRS)) to
provide sufficient supplemental On-Line capacity. If sufficient supplemental capacity is already
planned by Market Participants to be available, ERCOT will not need to initiate a SASM to
procure the additional Ancillary Services.
• In the event that additional Ancillary Services are unable to be procured through a SASM,
ERCOT will use the RUC process to procure any additional quantity of supplemental capacity
that is needed to maintain reliability.

WMS Report
New Supply Analysis Working Group (SAWG)
The SAWG is a result of combining the Generation Adequacy Task Force (GATF)
and the Resource Adequacy Task Force (RATF).
Minimum Point-to-Point (PTP) Option Bid Price
The TAC voted to approve ERCOT staff’s recommendation that the minimum
PTP Option Bid Price remain at $0.01/MWh for 2015. (Protocol Section 2,
Definitions and Acronyms, under Minimum Pont-to-Point (PTP) Option Bid Price)
Responsive Reserve Service (RRS) Under 2015 Ancillary Service
Methodology and the BAL-003 NERC Standard
In January 2016 the contingency reserves are likely to increase due to NERC’s
Resource and Demand Balancing (BAL) standard BAL-003, Frequency Response
and Frequency Bias Setting. BAL-003 provides a consistent method for
calculating the frequency bias component. The WMS and the SAWG will look
at BAL-003 and how it relates to ORDC and current ERCOT contingency
reserves. (It was noted that contingency reserves do not only include RRS.)

Ancillary Service Redesign
• NPRR667, Ancillary Service Redesign – Comments
requested by January 21, 2015
• If necessary, a Workshop to review the Comments will
be scheduled for January 28 or January 30
• ERCOT held a kick-off meeting with the Brattle Group
– The Cost Benefit Analysis (CBA) scope-of-work
details are still being worked out
• The CBA timeline will be nailed down in January 2015,
but the final CBA report should be posted in late
spring 2015
