ERCOT This week, 7x24 real-time prices have averaged in the low $20s/MWh across most zones. Plant outages for maintenance are still averaging over 20,000 MW, but, because of strong output from renewables and moderate temperatures keeping average peak loads under 50,000 MW, reserve margins are ample. The exception is the West Load Zone, where congestion remains significant (predominantly during off-peak hours) and average 7x24 real-time prices are $35/MWh higher than prices in the West Trading Hub for the week. Term prices down the curve are lower than last week by $0.25-$0.50/MWh because of a dip in natural gas prices, but heat rates are relatively consistent.
EAST As weather forecasts for December have normalized since earlier forecast runs but January is still expected to be unusually cold, term prices for the next three months have fluctuated but generally evened out over the past week. On the other hand, Real Time prices in Mass Hub spiked at $425/MWh in HE6 this morning be-cause of congestion in exports leaving Connecticut; one unit may also have had issues when ramping up. Overall, Real Time prices in Mass Hub for the week have averaged $42/MWh, about $1/MWh over the Day Ahead average.
