What to get from this presentation
• Understand what CHP is.
• Understand how it can help.
• Understand it is available Now.
• Not understand why CHP is not more widely utilized.

A well kept secret!
In 1910 Fuel utilization was 65%Today, nearly 100yrs later, it is only 33%

Waste of Energy
67% of Central Power Station Input Energy is lost in the form of Heat.

Grid Efficiency
As delivered to the customer electrical efficiency has stagnated for the last 40 years

CHP Comparison
CHP Recycles the Waste Heat from Power Generation achieving efficiencies of over 80%.

US CHP Goal92GW by 2010
Recognizing the benefits of CHP. Both the EPA and DOE support the goal of 92GW by 2010
Renewable Energy Workshop, January 19, 2007
National Energy Policy
CHP can achieve efficiencies of 80% or more.

The CHP SolutionNational Perspective
• Inadequate supply – Add up to 210 GWs of CHP.
• High energy costs – Cuts fuel by up to 2/3.
• Air pollution – Reduces emissions up to 2/3.
• Too few competitive suppliers – Many new ones.
• Major siting impacts – CHP plants small, near load.
• Long lead times – CHP in less than two years.
• Constrained transmission – CHP eases constraints.
• Power Security – CHP offers high levels of Security.
• Line losses of power – CHP suffers no line losses.
So why aren’t we building CHP everywhere?
Renewable Energy Workshop, January 19, 2007
To SummarizeCHP Can…..
• Reduce Fuel Consumption, easing our reliance on foreign fuel.
• Reduce Harmful Emissions of NOx and CO2.
• Increase Grid Security through Distributed Generation.
So why aren’t we building CHP everywhere right now?
Renewable Energy Workshop, January 19, 2007
Breaking Down the Barriers
• The barriers to CHP are not economics or technology but are regulatory.
• Florida’s Energy Plan lays the foundation of energy efficiency.
• CHP offers tomorrows energy efficiency dream today.
