Solar Power Savings Potential For 12.6 MW Installation District enjoys a long history as a resource conservation leader ( early 1980s DOE and CEC grants/loans, multiple performance contracts in the 1990s and 2000s, adoption of Energy Policy) M and O staff began actively exploring the comprehensive installation of solar energy systems in the District Applied for and was approved for $56 M in CREBs (Clean Renewable Energy Bond) in anticipation of installing solar in future Recognizing the benefits of solar energy, the installation of solar systems at all District facilities was a major facet of the Measure C Facilities Improvement Plan

District Electrical Cost / Consumption 2009 $3,200,000* Approximately 18 MW annual consumption* An initial analysis of District sites indicates that structures capable of producing at least 12.6MW could be installed (shade and parking) at District sites without having to utilize roof space. * According to PG&E supplied data

California Solar Initiative In 2006 the CPUC collaborated with the CEC to develop the framework of the California Solar Initiative (CSI) through 2016 For larger solar installations the CSI offers financial incentives based on actual performance of the system (s) for the first 5 yrs. 1,750 Megawatts of incentives offered in 10 declining steps. Presently level 7 only has 1.5 megawatt left of eligibility until the program slips into level 8 MDUSD has submitted level 7 for 12.6 MW of solar system installation Reservation requires a refundable deposit

California Solar Initiative Rebates for the installation of solar power Based on the Watts installed/verified system CSI level 7: 12.6 MW=$3,423,000/yr for 5 yrs (17 million over 5 years)* * The $2.8 million/yr cited in docket was based in a 10.4MW installation

PG&E vs Solar PG&E has gone up 6.7% a year since 1970 Owning our power source locks down the cost Conservatively, we forecast with 5.5% Includes a.7% per annum production degradation factor (industry standard is <.5%) 6.7% is from 1970 to 2005 data for calculation reference:

Cumulative Savings Forecast Year after year cumulative savings Based on avoiding utility increases (5.5%) Includes California Solar Initiative rebates 40 yr cumulative savings (cost avoidance) of approximately $386,000,000

Solar Energy Will Yield Long-Term Savings Low Environmental Impact Shade Structure Installations Enjoy a Very Low Level of Vulnerability to Vandalism and an Extremely High Level of Utility Sustainable, Long-Term Energy Source Reduced Carbon Footprint Predictable Energy Cost Underscores Districts Commitment to the Community as Stewards of resources/environment Creates Real World Curriculum Long Term Solution Results in a conservative 40 yr cost avoidance (savings) of $386 Million Dollars
