There are several key factors to power plant competitiveness, among them is the price of electricity, fuel price, personnel costs, consumables and maintenance Perhaps the most important dynamic shaping the U.S.: power market in recent years has been the volatility of fuel prices - specifically the fluctuating and high cost of natural gas. Over the past several years in the U.S., wholesale spot natural gas prices have increased significantly, from lows in a range from USD2.00 to USD3.00/MMBtu during late summer of 2001 to almost USD17.00/MMBtu shortly after Hurricane Rita in 2005.
