Drivers Changing Power Industry
• Deregulation and electric utility restructuring
− Market-driven environment − Profitability and investment concerns − Aversion to risk • Low cost of natural gas − Gas technologies favored over alternatives − Most new capacity to be gas-fired turbines and combined cycles • Environment − Pressure to reduce emissions, especially NOx, fine particulate, mercury − Concern over global climate change (CO2 emissions)
Technology innovation is the best way to address the coming challenges to our electric power and fuel supply infrastructure.
