  2. RCC Comprehensive Energy ModernizationAction Plan Presentation Contents • CCC/IOU Partnership Program • The need for energy modernization projects • Review of project progress/evolution • Initial project recommendations • Questions/Discussion/Input • Next actions and timeline

  3. Overview of the CCC Program What is the CCC-IOU EE Partnership? • A unique energy efficiency program; administered by the four IOU’s. The program is intended to: • Improve CCC facilities and lower operating costs at campuses statewide • Allow the CCC to leverage the local bond dollars and statewide project funding • Consist of several components focused around efficiency and education: New construction and retrofit projects Retro-commissioning projects Training and education projects Emerging Technologies • Through this incentive program, the utilities will offer administrative and technical support. Utilities will also be responsible for verifying the savings and the project at completion. • This program is funded by the California rate payer and administered by the four public IOU’s under the auspices of the California Public Utilities Commission.

  4. Overview of the CCC Program (Continued) What is the timeline? • The program will run from January 2006 to December 2008 • The project applications for the Community Colleges will begin on October 15th and run through November 15th of 2005 • Projects will go through a two form process: Form One (Initial) and Form Two (Detailed Project Proposal) • The Project Forms will be applicable to all Retrofit, New Construction, Retro-Commissioning and Emerging Technologies Projects. • Project Implementation will begin January 1, 2006

  5. The need for energy modernization • Aging equipment and systems that waste energy • Air quality requirements that must be met • Rising maintenance costs on chillers, boilers • Control of escalating electric and natural gas costs • Demonstrate environmental leadership to the community • Consistent with master plan and included as a bond project

  6. Review of Project Progress/Evolution • Late 2002: RCC explores energy modernization and renewable energy supply options • February 2003: RCC interviews several firms and selects NORESCO to perform a Preliminary Energy Conservation Audit • April 2003: Preliminary Assessment completed/presented • December 2003: RCC Facility Improvement Plan incorporates energy efficiency and supports alternative energy options • Ongoing: Implementation of the Facility Improvement Plan • Present: NORESCO under contract to prepare an Investment Grade Audit

  7. Audit Approach/Objectives Performed by NORESCO • Initial walk-through inspection • Objectives and goals of the client were identified • Review (available) plans and specifications • Interview building operating personnel • Perform analysis of utility cost and use • Identify potential energy modernization/conservation measures • Estimate costs, savings and benefits of the identified measures

  18. RCC Comprehensive Energy ModernizationAction Plan PreliminaryRecommendations Norco and Moreno Valley – Photovoltaic system • Base case: Neither campus has renewable energy supply sources currently in place. • Investigated: Norco - A ground mounted 30kW system and Moreno Valley a 30kW ground mounted system Norco Moreno Valley Cost $527,174 $527,174 Rebate (CEC) $ 84,000 $ 84,000 Net Cost $443,174 $443,174 Annual Savings $ 6,323 $ 7,095 Annual KWH savings 51,800 51,800 (2.5% Annual Savings) Payback (Years) 70 62 Riverside campus – Costs and savings under development Investigation results: Investigation has shown that the current technology and costs make a viable project challenging. If future rebate levels increase and technology improves, the viability may become favorable.

  19. What other projects did NORESCO investigate? • Cogeneration: Analysis showed marginal financial results for the Norco and Moreno Valley campuses; waste heat could not be consistently used. The Riverside campus is under review. High current prices for natural gas pose a significant challenge. • Water conservation: Most interior plumbing fixtures are currently efficient; some opportunity exists for irrigation water management • Re-Cycling: An opportunity exists if a third party contractor can be located that will assume 100% responsibility without cost • Thermal Energy Storage: The CCC/IOU Program does not offer targeted incentives but the option may become more viable in the future

  20. Next Actions and Timeline • CCC/IOU Partnership Form 1 submitted 11/22/05 • CCC/IOU Partnership Form 2 estimated release Dec 19 • Complete the review and selection of projects with RCC • Verify the various funding sources: rebates, bonds, loans • NORESCO completes the Investment Grade Audit within 30 days • Present support/endorsement from Strategic Planning Committee • Seek Board of Trustees approval to proceed with NORESCO under a design/build fixed priced, guaranteed maximum contract • NORESCO provides an Energy Services Agreement • RCC action/approvals to proceed to implementation

  21. As of December 19, 2005From Fred Harris Assistant Vice Chancellor of College Finance and Facilities Planning • To continue with the process RCCD will need to submit the following documents: • 1. Complete form 2. • 2. Provide supporting documentation and calculations. • 3. Provide commitment in writing of campuses. • Form 2 and supporting documentation will be accepted until 5 pm Friday February 3, 2006. • Newly revised extended date to February 17, 2006

  22. Partnership Program Incentives • Partnership program incentives are based on annual savings and are more lucrative then traditional utility programs. • Incentives cannot exceed 80% of the energy efficiency projects. • .15 cents per KWH for lighting. • .24 cents per KWH for motors, drives and package units. • .32 cents per KWH on central plants or major energy efficient infrastructure improvements. • $1 per therm on gas measures.
