ERCOT’s Technical Advisory Committee has canceled its Oct. 26 meeting because of a limited number of items for consideration. The TAC will instead hold a one-hour web information session Monday to prepare for an email vote on the load distribution factor (LDF) library.
Staff will discuss the methodology behind generating and maintaining LDFs used in the congestion revenue rights (CRRs) and day-ahead market clearing activities. LDFs are developed using historical state estimator or supervisory control and data acquisition (SCADA).
ERCOT protocols require the ISO to maintain the appropriate LDF libraries for use in the day-ahead and CRR auctions. Staff updates the libraries by maintaining the existing LDF sets and generating new LDF sets when required, based on significant changes in systemwide load patterns.
TAC Vice Chair Bob Helton has yet to set a date for the email vote.
ERCOT Approves Barney Davis Gas Unit’s Retirement
ERCOT on Thursday approved the retirement of a 330-MW gas unit at the Barney Davis plant near Corpus Christi, saying it is not needed to support system reliability and can now be decommissioned.
Talen Energy announced on Sept. 27 its intention to retire the unit, triggering ERCOT’s reliability review. The unit went into service in 1974.
