Electricity peak prices at the Western hubs increased $3-23/MWh and decreased $6-57/MWh at the Eastern hubs. According to Platt’s Electric Power Daily (5/16/08), ERCOT has seen “its share of volatility in recent months” due to “an influx of new wind generation and not enough transmission… In 2006, there were 75 15-minute intervals in which real-time prices fell below $0/MWh. So far this year , there have been already more than 2,250 occurrences” (see pages 1 and 3).For the report click here. It is also located on NEI's Financial Center webpage.
