  1. Build It GreenSustainability through Energy Service Projects Alameda County General Services Agency DGS’s Energy Efficiency Forum September 27, 2006

  2. What You Can Save Energy Program: 1987-2006 • Total Energy Capital Projects Value = $35 M • Total Energy Incentives and Refunds = $17 M • Current Annual Utility Budget = $11 M • Current Annual Energy Cost Avoidance = $5.5 M

  3. The Energy Program Team Established in 1987 GSA/TSD • 1 Program Manager • 1 Project Manager • 2 Electrician/Construction Coordinators • Project and Cost Savings Oriented

  4. Why Solar for Santa Rita Jail? 1.2 mW Santa Rita Integrated Solar Power Project Available Roof space Lots of Sunshine Large Electric Load

  5. How Did We Do It? • PowerLight developed full proposal • Sole source procurement to small local firm • Combined with other energy efficiency measures • Chiller Plant Retrofit • Cool Roof Application • BAS Controls Upgrade • Financing from $1.9M from CEC Energy Loans • Negotiated Energy Services Contract (CA code 4217) • Secured $4.5M PG&E/CEC Buydown Incentives • Secured $400K special legislative grant

  6. Why Fuel Cell Cogeneration? • Ultra-clean, no-combustion technology – No Air Quality Permit • Quietly Delivers High Quality electricity and heat • High-efficiency generation • Power plant natural gas turbine: 35% efficiency • Fuel Cell: 49% efficiency • Grant Incentives Available

  7. Why Fuel Cell at Santa Rita Jail? • Jail’s needs accommodate megawatt size of plant for electricity and heat generation • 24-7 operation with a megawatt base load (fuel cell in continuous operation) • Had unused outdoor space within perimeter fence and close to central plant to tie into hot water and electrical distribution system • Fuel cell/solar power generation synergy

  8. Project Finances • $6.1M capital cost • $2.3M DoD & PG&E grants • $2.8M CEC Loan • $1M Energy Fund • Internal rate of return 10% hurdle

  9. How Did We Do It? • Performed Distributed Generation study in 2002 : Environmental Benefit vs Cost • Received $1M DoD Fuel Cell Grant in early summer 2004: (made project possible) • Issued RFP in mid 2004 • Chevron Energy Solution/Fuel Cell Energy responded in late summer 2004 • Issued Fuel Cell Plant P.O. in Fall 2004 • Negotiated Energy Services contract & 13- year Long-Term Full Service Agreement with 2 restackings in Spring 2006 • Awarded Contract early summer 2005 • Received PG&E Self-Generation Incentive fall 2005

  10. Started Construction October 2005 90K lb Fuel Cell Module 65K lb AGO Skid

  11. 1 mW Santa Rita Fuel Cell Energy Center Online at Full Power May 2006

  12. Fuel Cell Benefits • $864K/yr Electrical savings • 50% Electricity • Natural gas -> cleaner energy • 18% Heat • $260K/yr Net Savings • = 900 acres of trees 60% Jail’s electricity from onsite ultra-clean energy

  13. Sunset over the Solar Power System at Santa Rita Jail Matthew Muniz, P.E., Energy Program Manager County of Alameda, GSA/TSD, (510) 208-9518 email: matt.muniz@acgov.org
