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

 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

CPAU Delivers Five Utility Services

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)

 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

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)

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

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

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

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

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

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

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

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
