Technical Advisory Committee Chair Bob Helton has canceled the committee’s Aug. 28 in-person meeting because of a “limited number of items” for consideration.

Instead, the TAC will hold an online information session on the Real-Time Co-Optimization Task Force’s (RTCTF) latest work to develop real-time co-optimization (RTC) principles. RTC is a market tool that will procure energy and ancillary services every five minutes to find the most cost-effective solution for both requirements.

The task force plans to present three key principles (KPs):

• KP1.4: telemetry changes associated with any change to the resource-limit calculator logic;
• KP1.5: process for deploying ancillary services; and
• KP3: reliability unit commitment settlement.

The committee will conduct an email vote on the principles after the meeting.

The task force has until February to draft the principles that will guide RTC’s design in adding ancillary services to the real-time security-constrained economic dispatch engine. The TAC in July approved the task force’s first five RTC key principles. (See “TAC Approves First Real-time Co-optimization Principles,” ERCOT Technical Advisory Committee Briefs: July 24, 2019.)
