Six months after ERCOT's RTC+B go-live, day-ahead prices are down 15.5% and real-time prices are down 11.6% compared to the same period a year earlier.
A few other things the first six months of data show:
→ Energy DART spreads shrank roughly 50%, and flipped negative at three of five hubs
→ Solar's share of generation rose about 5% and batteries about 1%, while coal, gas, and nuclear each slipped 1-2%
→ Virtual ancillary services (AS) participation climbed from about five qualified scheduling entities (QSEs) to roughly 18 offering daily
→ Zero virtual ECRS or RRS awards so far, despite plenty of offers
Senior Power Market Analyst Alex Sheldon digs into what changed, what the data actually says, and where the open questions are — including why non-spin is the one AS product that got more expensive.
