Transcript

  • 1. Palo Alto: Going Carbon Neutral by Going Big on Solar Jim Stack, Ph.D. Senior Resource Planner Lindsay Joye, P.E. Solar Marketing Engineer Vote Solar Webinar July 24, 2013
  • 2.  26 square miles  Territory runs from the SF Bay to the Mountains  Population: 64,000  Employment: >80,000  Approximately 29,500 customers (73,500 meters) Palo Alto at a Glance
  • 3. CPAU Delivers Five Utility Services
  • 4. 4 Palo Alto’s Electric Utility  Not CPUC regulated – City Council is decision- making authority  Annual load: ~1,000 GWh  Peak: 190 MW  Current Supply – Hydroelectric – Wind – Biogas (LFG) – Natural gas (and RECs) – Some local solar (NEM)  Future Supply – Large solar (utility scale)
  • 5.  Utilities Incentive Programs  Rebates, Solar water heating, NEM, DR, and more  Renewable Portfolio Standard (2002)  33% by 2015 with a rate impact up to 0.5 ¢/kWh  PaloAltoGreen (2003)  City’s Climate Protection Plan (2007)  Community-wide GHG emissions 15% below 2005 level by 2020  10-year Energy Efficiency Plan (2007)  Feed-in Tariff Program (Palo Alto CLEAN) (2012)  Local solar Feed-in-tariff at 16.5 ¢/kWh for a 20 year contract  Carbon Neutral Electric Portfolio Plan (2013) Key Climate Initiatives
  • 6. 7 Electric Supply GHG Emissions 0 20,000 40,000 60,000 80,000 100,000 120,000 140,000 160,000 180,000 200,000 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 2016 2017 2018 2019 2020 TotalElectricitySupplyEmissions(TonnesCO2e) Calendar Year Total Emissions (Actual / Projected) Total Emissions (Carbon Neutral Plan) Total Emissions (Average Hydro) Actual Projected
  • 7. 8 8 Solar Accomplishments  1999: PV Partners Rebates for Net Metered PV  2003: PaloAltoGreen voluntary 100% renewable  2012: PA CLEAN Feed-in Tariff for PV  2013: Carbon Neutral Electric Portfolio  2012-2013: Solar Power Procurement (PPAs)
  • 8. 9 Palo Alto Green  Voluntary renewable energy program, started in 2003  Premium 1.5 ₵/kWh  100% renewable energy credits from CA solar  >21% of customers are on PAGreen  Ranked #1 in US for last 5 years
  • 9. 10 PV Partners Program  Rebates for Net Metered PV systems  Started 1999  Increased funding in 2007 (SB1)  6.5 MW goal by 2017  Current rebates: – Residential: $1/watt – Non-Res: $0.25/kWh paid over 5 years - 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 1999 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 Cumulative Installed PV Capacity (MW) Residential NonResidential
  • 10. 11 Distributed Generation  Avoided transmission & capacity costs ~$30/MWh  Wind and biogas – low potential  Solar PV is most viable – Limited space for ground mount – Best suited for rooftops and parking lots
  • 11. 12 Palo Alto CLEAN Concept  Clean Local Energy Accessible Now  Fixed Feed-in Tariff paid for 20 year term  Interconnected on utility side of meter  CPAU buys electricity, renewable energy credits and capacity attributes  Energy used to meet Renewable Portfolio Standard goals  Price based on value of local renewable electricity to CPAU
  • 12. 13 PA CLEAN Details  2012 price = 14 ¢/kWh  2013 price = 16.5 ¢/kWh  No minimum project size  2 MW program capacity  Continued outreach to property owners, solar developers & CLEAN Coalition … no projects, YET
  • 13. 14 PA CLEAN: Ideal Candidate  Has available rooftop space  Interested in generating green energy, but not able to use it themselves (e.g. building owner who leases the building to tenants who pay utilities)  Looking for additional revenue from their rooftop  May develop the project themselves or lease the roof to a solar developer
  • 14. 15 PA CLEAN Lessons  Challenging to find suitable locations  Hard to compete with higher ROI for net metered PV  Hard to locate property owners who don’t pay utilities and want to monetize roof or parking areas  City may need to offer additional services to match property owners with developers
  • 15. 16 Palo Alto’s RPS History 2002 2006 2007 2011 20% by 2017 (SB 1078) 10% by 2008, 20% by 2015 20% by 2010 (SB 107) 20% by 2008, 30% by 2012, 33% by 2015 33% by 2015 33% by 2020 (SB X1-2) California Palo Alto
  • 16. Contracted RPS Resources 0 100 200 300 400 500 600 GWhperYear Large Solar PA CLEAN RECs Landfill Gas Wind Small Hydro 33% RPS Target 100% Carbon Neutral Portfolio
  • 17. Hydro 53% Wind 12% LFG 11% Solar 23% Market Power 0.7% 2017 Hydro 43% Wind 12% LFG 7% Market Power 38% 2012 Palo Alto’s Resource Supply Mix
  • 18.  Open, competitive solicitation process  Issue an RFP once a year (approx.)  No unsolicited bilateral deals  Response rate has grown exponentially  Over 90 project proposals received in 2012  City staff negotiates PPA with seller  3 step approval process after seller executes  Utilities Advisory Commission, Finance Committee, City Council RPS Procurement Efforts
  • 19.  Go shopping fairly often/regularly  Get the word out across the industry  Streamline and simplify the proposal submission process as much as possible  “Just the facts”  Be very clear and very specific about what types of offers will be accepted  Establish objective evaluation criteria  Before issuing the RFP! RPS Procurement Lessons Learned
