1 An Airport Sustainable Energy Strategy Addressing the Ecology, Equity & Economics of Airport s Energy Usage March 2015 Paul Manasjan - Director, Environmental Affairs San Diego County Regional Airport Authority

2 Sustainable Energy Strategy Overarching Objectives Energy Efficiency & Conservation Energy Independence Carbon Neutrality Cost Containment Leadership: Mastering the Art of Airports 2

3 Airport s Energy and Water Concerns 20% Decrease in regional energy resources 80% imported Limited water supply; water-energy nexus 52% 22% over last year Energy use major source of carbon print Escalating energy rates 26% increase for 1 st Quarter FY 15 22% increase annualized 3

6 2012 Greenhouse Gas Emissions Inventory Airport Owned or Controlled Carbon Emission Sources Construction Low emissions vehicle conversions C & D recycling Ground Serv. Equip. (GSE) Low emissions vehicle conversions Off-Airport Vehicles Low emissions vehicle conversions On-Airport Vehicles Low emissions vehicle conversions 2% 5% 17% 24% Up to 30% reduction with PV 52% Energy Usage Energy efficiency and conservation measures (LEED) Maximize use of renewable energy (Photovoltaics) Carbon Reduction Strategies 6

7 Energy Strategy Development Recommendations Install airport-wide electrical microgrid system Employ utility-grade supervisory control & data acquisition system (SCADA) Develop alternative energy resources such as solar, cogeneration and fuel cells Pursue LEED certification to demonstrate energy efficiency features 7

8 Leadership in Energy and Environmental Design (LEED) Terminal 2 Expansion Receiving & Distribution Center Dual-Level Roadway Cargo Facility (planned) Fixed Base Operation -or better- Existing Building Facilities Management More Sustainable, Energy-Efficient Buildings 8

9 Terminals 1 and 2 receive power from existing 12-kV lateral distributions Remaining airport facilities receive power from over 100 different meters from SDG&E Central Plant = electrical meters = 12kV lateral distribution line Existing Power Distribution System >100 Electrical Meters 9

10 Current State Issues Lack of comprehensive connectivity throughout airport Lack of campus-wide power reliability or redundancy 10-15% power loss through lateral distribution system Many industrial meters on campus = $$$$ 10

11 New Microgrid System Campus-wide Energy Energy Distribution Distribution Supports connectivity to entire airport & facilities Reduces electrical interruptions by rerouting power around loop Capable of 30MW power distribution to support future growth Enhances redundancy 12kV Microgrid Loop Reduces number of electrical meters which reduced costs (>100 3) 11

12 10MW photovoltaics (PV) 18MW cogeneration Planned Microgrid Energy Distribution System 2MW fuel cells battery energy storage 10 MW PV + 20 MW Co-Gen & Fuel Cell 30MW Future Capacity 12

13 Solar Implementation Plan Program History Airport s Sustainable Energy Strategy includes the use of solar generated power to help: Reduce Airport s carbon footprint Control cost of electricity Electrical power will be provided to Airport through Power Purchase Agreement (PPA) Dec 4th, 2014 Board Authorized T2W PPA Dec 20, 2014 Solar Photovoltaic (PV) RFP issued for Economy Parking Lot and Rental Car Center 13

14 Benefits of Power Purchase Agreements (PPA) PPA firm will own, design, install, operate, & maintain solar PV generating system. Power will be provided to Airport at fixed price over a 20-year term No capital is required by Airport to finance system No PV maintenance required by Airport *PPA approach allows for provider to monetize incentives and pass on back savings to purchaser Airport only pays for power produced by PV system Cost of power is lower than utility rates today and more so in future Excellent option for public entity to take advantage of tax incentives* 14

15 Proposed Solar Implementation Plan North Side There are two solar PV locations associated with this project that will generate a total of approximately 5.1 megawatts (160 million kwhs over 20-years) Rooftop of RCC Economy lot solar carport structure 3.0 MW 2.1 MW 15

16 Proposed Solar Implementation Plan North Side Rental Car Center (RCC) roof installation On rooftop of RCC On custom structure to allow rental car parking beneath 16

17 Economy Parking Lot Solar Carport Structure Typical carport installation Typical T-structure carport T structure carport over parking bays Drive aisles remain clear North Side Proposed Solar Implementation Plan Economy Parking Lot 17

18 Solar Implementation North Side Total cost of solar power generated over 20 year period: $22.3M at 100% energy production $24.5M at 110% energy production At the end of the Power Purchase Agreement: System can be purchased by the Airport Authority at fair market value System can be removed at no cost to the Airport Authority; or Airport Authority can extend the Power Purchase Agreement 18

19 Three North Side Energy Options PV Solar No PV Solar PV Solar Buy All Power From SDG&E Carbon Emissions Reductions NO Self-Financed Carbon Emissions Reductions YES Through Power Purchase Agreement (PPA) Carbon Emissions Reductions YES Cost Savings NO Cost Savings NO Cost Savings YES 19

20 Energy Costs in $ Millions (M) Year Financials of Power Generation Options SDG&E with No PV Airport Build/Operate PV PV with PPA $60M $50M $40M $30M $20M $10M Total Cost = $40.7 M SDG&E Total Cost= $40.7M ($0.25/kWh) Total Cost = $49.4 M SDG&E PV tariff = $14.7M ($0.09/kWh) Airport owned PV= $34.7M ($0.22/kW) Total Cost = $36.9 M SDG&E PV tariff = $14.7M ($0.09/kWh) PPA Cost= $22.3M ($0.14/kWh)

21 Conclusion Escalating operational costs associated with dwindling regional resources will continue to drive innovation and value of sustainable asset management. 21
