  4. The Case For Micro-Grids Heavily burdened, aging electrical grid The toll of power disruptions

  5. How a Microgrid Works

  6. White Oak Microgrid

  7. FDA White Oak Challenge • Mission: • Campus integrates FDA’s functions to increase scientific synergy and collaboration. • • Protect consumers from unsafe products, address threats before they arise, and help deliver safer foods and safer, more effective medical therapies. • Needs: • Energy Security • Energy Surety • Energy Efficiency & Renewable Energy Mandates • Ability to Expand as Campus Expands Requires an islanded microgrid to meet GSA/FDA requirements • Challenges: • Budget Constraints (New Construction ESPC) • Ability to Balance Sometimes Conflicting Needs • Aging Utility Infrastructure

  8. Optimization – Key to Success Initial Strategy Near continuous operation of engine-generator Current Operations Real-time “make or buy” decision based upon cost of natural gas, electric tariff, campus loads vs. engine & cogeneration efficiencies Additional Value: • Expanded Auto Load Shed Scheme • Additional Dual-fuel Generation Assets • Combined Heat and Power – Maximizing BTUs • Interconnect Agreements With the Utility Honeywell, GSA and FDA Work Together to Operate the Facility in the Best Interest of the Government.

  9. Innovative ECMs Waste heat utilized to heat/cool buildings. More BTUs for every KW. Combined Heat & Power (Trigen) Quantified above standard efficiency in new buildings, purchased equipment and provided funding. NewConstruction Chilled Water Thermal Energy Storage Water supply was single point of failure – needed to keep cooling towers operational. Chilled Water Storage connected to towers mitigating risk. Automated Demand Response (Auto DR) Instituted capability to participate in Pepco Gold Days putting power back on the grid when requested. Eliminated peak load charges as well. Adding capability to use biofuels for fuel flexibility for energy security and increasing options if natural gas prices increase. Biofuels Lowered Total Energy Consumption Through Both Innovative and Traditional ECMs Throughout The Entire Campus.

  10. Reliability Enhancements • Utility Service Enhancements • Physical and Functional Separation of Utility Generation Systems • Electrical Bus Ties between Central Utility Plants (CUP) 1 and 2 • Dual Distribution Loop For Redundancy • Two Additional Black Start Generators • CUP and Building Level Load Shed • Thermal Energy Storage • Electrical Load Shed of Chillers • Backup Water Supply Electricity Produced Turquoise -CUP Generators Blue- Photovoltaic Arrays MW hrs

  11. Reliability Features • Fast, Dependable Separation From Utility Instability • Reliable Detection of Utility Deviations • Instantaneous Separation to Island Mode • Operation With Adequate Spinning Reserve • Smooth Generator Transition To Load-Sharing Island Mode Control • Fast Load Management for Generator Demand Control, When Required • Accurate Real-Time Generator Capacity and Spinning Reserve Assessment • Fast Updated Load Measurement • Fast Load Shed of Prioritized Demands • Coordinated Load Restoration Process • Synchronized Transfer from Island to Utility Parallel Operation • Black Start Capability to Island Mode Operation

  12. Reliability Metrics Island Mode Uptime Redundancy Power Generation Uptime over the last 12 months is > 99.999%. Redundancy provided for all critical systems. Islanded, either automatically or manually, more than 70 times over the past 2 ½ years. Operations have not been interrupted for any weather related events. On a yearly basis more power is supplied to Pepco than Pepco supplies to the White Oak Campus.

  13. The Benefits • Annual Energy Savings • Current: 640,000 MMBtu • Under Construction: 275,000 MMBtu • Pollution Prevention (annual) • Current: 50,000 metric tons CO2-equivalent • Under Construction: 22,000 metric tons CO2-equivalent • Co-Generation reduces GSA NCR Demand • Response during “Gold Days” (approximately 22 MW currently; nearly 33 MWpost-ESPC III Base) • Rainwater Harvesting • Makeup water for cooling towers 30% Reduction from Baseline Equivalent to 15,000 Cars Removed from Road $3M in Demand Savings and Program Participation Good water stewardship

  14. Summary of Benefits • Reduced First-Cost to Government • Reduced Recurring Costs to Government • More Energy Efficient Campus • Fixed Accountability for Systems Performance • Flexibility to Meet Evolving Program Requirements • Adaptive Re-use of Historic Structures • Demand Response Capability ($ to GSA) • Ability to Continue Mission Independent of the Grid • Enhanced Energy Security

  15. THE CITY OF Wilmington DELAWARE Hay Road Waste Water Treatment Plant Renewable Energy Biosolids Facility Maryland Clean Energy October, 2013

  16. In June 2009, Wilmington initiated a Project to • Reduce energy and operational costs • Reduce greenhouse gas emissions • Insulate the City from future electricity and biosolids cost escalation • Two phases: • Phase I completed in September 2011. • The REBF is Phase 2. • Honeywell guarantees cost savings over a 20 year period

  17. Overview of Projects • PHASE 1 completed October 2011 • Solar Panels at Porter and Municipal Complex • Building Energy Savings • LED Traffic Lights • Water Pumping Peak Load Shift • PHASE 2 • 4 Megawatt Electricity Generation Using Renewable Fuels • Dry 140 Tons Per Day of Wastewater Sludge • Estimated to Save Over $16 million

  18. Landfill Gas Plant Cherry Island Landfill

  19. Landfill Gas Plant

  20. Wilmington Microgrid – What Has Been Accomplished

  21. REBF Project Benefits • Save $16.7 Million Over 20 years • >$800,000 Reduction in Annual Costs • Achieve budget certainty • Fix Electricity and Biosolids Costs Over 20 years • Reduce Greenhouse Gas Emissions by 15,000 Metric Tons Per Year • Exceeds 20% Greenhouse Gas Reduction Goal • Over 50% of Wilmington’s Electricity Requirements Will Be Met By Its Own Renewable Energy • Spend Locally • Avoid Exported Utility and Sludge Hauling Costs • The Majority of Construction Subcontracts Go to Local Firms • Over 100 Local Construction Jobs • All Labor Drawn from Wilmington Locals
