The Problem
• Fluctuations in intermittent renewables must be balanced with fast-ramping resources.– Adds cost and emissions

Research Objectives
• How does the “CHP strategy” compare to traditional, centralized gas turbines?
• How much CHP is needed to balance a given penetration of intermittent renewable generation?

Regulation Markets
• Regulation requirement in PJM is ~1000 MW (1% of daily peak).
• 25% of this requirement can be met by demand-side resources.
• There was not a single demand-side resource participating in the regulation market in 2008.
