Weather and force majeure - Force majeure provisions for power contracts

In the early hours of September 13, 2008, Hurricane Ike made landfall between Galveston and Baytown, Texas. Ike had tropical storm-force winds extending 550 miles from its eye, including winds of 110 mph. It registered the highest recorded level of the appropriately named Integrated Kinetic Energy (IKE) of any Atlantic storm in history, at 149 Terajoules. Within hours, more than 90% of electrical customers in the Houston metropolitan area (more than 4.5 million people) lost electrical power.
