Transcript

  • 1. Keeping The Lights On: Energy Resiliency In Redevelopment March 14th, 2014 NJ Futures: Redevelopment Forum 2014 Mark Warner Energy Director Sustainable Jersey
  • 2. What Is Energy Resiliency? Energy Is A Critical Resource During Emergencies The Energy Supply For A Facility Is RESILIENT If It: •Is less prone to failure •Allows at least basic operations during a primary system (grid) failure •Facilitates easier/faster/safer recovery of the primary system In Practice, This Means Facilities That: •Have a locally controlled power generation capability (back-up generator) •The ability to disconnect from the grid (islanding) •Arrangements that minimize dependence on vulnerable fuel supplies
  • 3. Resiliency Vs. Sustainability Sustainability Is Focused On An Energy Infrastructure That Is: •Affordable •Clean •Inexhaustible •Safe and Universally Available •Secure and Reliable Actions To Improve Resiliency Often Improve Sustainability: •Less dependence on fossil fuels •Use of cleaner fuels, reduced fuel vulnerability •Increased use of renewable energy and storage •Increased generation efficiency •Improved local energy reliability during failures of the primary system (grid) •Can improve overall grid performance (power quality, reduced peak loading)
  • 4. Energy Resiliency Technologies: Generation Back-up Generation Solutions: •On-site diesel generator •Natural gas generator (fed from distribution system) •Natural gas fuel cell •Combined heat and power solutions •Adding electricity storage to on-site renewables (especially solar) Image Source: U.S. Department of Energy Combined Heat And Power Solar Plus Islanding And Storage StorageStorage
  • 5. Energy Resiliency Technologies: Local Distribution Customer Local Distribution Capabilities: •Overall energy efficiency •Islanding and storage •Micro-grids Islanding Switch Islanding Switch Central Power Plant Traditional Consumption Loads Public Grid Micro-Grid
