  1. Easing the Integration of Intermittent Renewables with Combined Heat and Power Kyle Siler-Evans RenewElec Workshop, 2010

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

  3. The Problem: Reduced Emissions Performance Source: Katzenstein et al., 2009

  4. The Problem: Added Cost Source: Based on 2008 PJM market data Cost of energy supply in PJM: Energy: ~$50 billion Capacity: ~$5 billion Regulation: ~$0.5 billion (~1%) Reserve: ~$0.03 billion

  5. Outline • Balancing Intermittent Resources with CHP • Encouraging Privately Owned Resources to Support the Grid • Spurring Adoption of CHP

  6. Combined Heat and Power Conventional Generation

  7. Why CHP? Source: Adapted from EPA, 2008

  8. Why CHP? Source: Adapted from EPA, 2008

  9. Example Scenario: Oversize industrial CHP Source: Adapted from EPA, 2008

  10. Example Scenario: Use excess capacity from underutilized CHP

  11. Example Scenario: Use excess capacity from underutilized CHP ~100 GW installed In U.S.

  12. 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?

  13. Outline • Balancing Intermittent Resources with CHP • Encouraging Privately Owned Resources to Support the Grid • Spurring Adoption of CHP

  14. 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.

  15. Regulation Market Prices Source: PJM 2008 market data

  16. Research Objectives • Evaluate existing opportunities for demand-side resources to participate in regulation services. • Designing new mechanisms for DSR participation where necessary.

  17. Outline • Balancing Intermittent Resources with CHP • Encouraging Privately Owned Resources to Support the Grid • Spurring Adoption of CHP

  18. Making CHP More Attractive
