9b Presentation Car Facility Bus Purchase
Item No. 9b_supp Meeting Date: January 8, 2019 Bus Procurement Projects Rental Car Facility Bus Purchase Employee Parking Bus Purchase Peter Lindsay and Leslie Stanton January 8, 2019 Briefing Overview Project description Current bus operations Future needs Goals and objectives Alternatives and schedule Results Recommendation 2 Bus Operations Orange route serves rental car passengers, blue route serves tenant employees 3 Project Description Rental Car Facility (RCF), C800810 Replace 5 expiring buses and add 1 spare bus Cost recovered through customer facility charge Employee Parking (EP), C800956 Replace 11 expiring buses and add 7 buses Cost recovered through employee parking rate Airport must purchase buses to maintain service 4 Goals and Objectives Port goals Reduce carbon emissions Meet growing air transportation needs Financial sustainability of GT operations Project objectives Maintain service Minimize cost Reduce carbon emissions Minimize operational impacts Bus fleet must meet service, financial, and environmental goals 5 Link to Framework Developing a Sustainable Project Framework that incorporates multiple sustainability goals into Port decision-making processes Bus procurement project offered an opportunity to test framework assumptions Bus procurement project was a real-time case study for the Sustainable Project Framework 6 Project Alternatives 1. Electric buses Requires charging infrastructure and additional buses FAA grant available but uncertain 2. Refurbished CNG buses with Renewable Natural Gas (RNG) New drivetrain, subsystems and interior 3. New CNG buses with RNG RNG is zero net carbon drop-in replacement for CNG Other operators currently use RNG for transportation Bus technologies differ in price and operational impacts 7 Schedule Commission briefing & authorization 2019 Q1 FAA grant results 2019 Q2 Bus/charger purchase (PO) 2019 Q3 Replacement buses in-use 2021 Q4 16 CNG buses retired (EP=11, RCF=5) 2022 Q2 Alternative must be selected by February 2019 to avoid service gaps Analyzing Alternatives Step 1: Objectives Maintain service Minimize cost Reduce carbon emissions Minimize operational impacts Step 2: Risks Fuel supply Maintenance requirements Analyzed each alternative for its ability to meet objectives and minimize risk 9 Project Costs Electric w/ Refurbished Electric RNG grant RNG Initial capital cost $36.6 $25.8 $11.6 $16.8 Average annual operational costs $0.7 $0.7 $1.0 $1.0 NPV of total cost of ownership (20 years) $57.4 $46.6 $30.8 $30.0 All costs in million USD 2018 Electric alternative has highest long-term cost 10 Carbon Emissions Refurbished CNG Electric RNG RNG Carbon emissions (tons CO2/year) 1,220 20 0 0 Expiring buses create 5% of Sea-Tac's Scope 1 and 2 carbon emissions RNG and electricity have similar carbon reduction benefits 11 Carbon Emissions RNG does not add carbon to the atmosphere 12 RNG Availability RNG for transportation is available Supported by federal incentive program Bipartisan support; low long-term risk Port is developing an RFP for RNG Supplies airport boilers and existing CNG bus fleet Seeking 10- to 20-year term RNG is currently available and long-term source is likely 13 Objectives and Risks Refurbished RNG Objective Electric RNG Objectives Maintain service Minimize total cost of ownership Reduce carbon emissions Minimize operational impacts Risks Fuel supply and price Maintenance requirements New CNG buses w/ RNG meet objectives with minimal risk 14 Recommendation New CNG buses fueled with RNG Meets objectives Reduces maximum amount of carbon Minimizes total cost of ownership Minimizes operational impacts Minimizes risk Less maintenance downtime than refurbished buses Allows EV technology to mature and prices to fall Port can revisit electric option prior to 12-year bus replacement Recommend purchasing new CNG buses and fueling them with RNG 15 APPENDIX 16 NPV of Project Costs (20 years) Electric w/ Refurbished Electric RNG grant RNG Total cost of ownership $57.4 $46.6 $30.8 $30.0 Charger capital and installation $10.4 $5.0 $0 $0 Initial bus capital $25.2 $19.8 $10.8 $15.2 Bus replacement $11.4 $11.4 $5.2 $0 Fuel $2.9 $2.9 $3.2 $3.2 Maintenance $7.5 $7.5 $11.5 $11.5 All costs in million USD 2018 Electric alternative has highest long-term cost 17 RNG Cost Federal incentives are greater than CNG commodity price Other U.S. airports outside of California have procured RNG at similar cost to CNG RNG price is likely similar to CNG price 18 Project Cost Summary Rental Car Buses 6 Employee Parking Totals new CNG buses Buses 18 new CNG buses Current Budget $1,800,000 $18,081,000 $19,881,000 Budget Increase/(Decrease) $2,603,000 ($5,646,000) ($3,043,000) Revised Budget $4,403,000 $12,435,000 $16,838,000 Recommended alternative results in net ~$3 million overall budget reduction Carbon Reductions Relative to CNG RNG Electric Refurbished RNG Emissions reduced relative to CNG 1,220 1,200 1,220 (tons CO2/year) $/ton of CO2 reduced relative to $0 $925 $0 CNG RNG and electricity have similar carbon reduction benefits 20 Carbon Reductions from RNG Sea-Tac Scope 1+2 emissions Natural gas is 80% of Scope 1+2 25K emissions Electricity 20K Fleet gas and diesel RNG is zero-carbon drop-in Bus CNG 15K replacement for natural gas Tons CO2 10K Natural gas boilers 5K K RNG for buses and boilers reduces Sea-Tac's Scope 1+2 emissions by 80% 21 Comparable Bus Operators Pierce Transit: primarily CNG Community Transit: diesel Microsoft: diesel and gasoline Amazon: diesel UW: gasoline Children's Hospital: gas/propane bi-fuel With RNG, the Port would remain a regional sustainability leader 22 Electric Utilities at Sea-Tac S 23 N
Limitations of Translatable Documents
PDF files are created with text and images are placed at an exact position on a page of a fixed size.
Web pages are fluid in nature, and the exact positioning of PDF text creates presentation problems.
PDFs that are full page graphics, or scanned pages are generally unable to be made accessible, In these cases, viewing whatever plain text could be extracted is the only alternative.
