2Future Hourly Price Topology

Trend 2002 – 2004 was higher average prices, lower price volatility

Most zones had sufficient generation or import capabilityOccasional episodes of higher mid-day prices, especially in the summer

2005 was differentOverall prices soared in the winter due to NG price risesHighest price volatility since 2002, despite adequate supplies

What’s in store for 2006-2008?Tightening supply situation in many zonesLimited transmission additions to relieve congestionUncertainty about NG and oil prices
