Solar Power Savings Potential For 12.6 MW Installation

Discover the long-term cost savings and environmental benefits of implementing solar energy systems in our district. With the California Solar Initiative and financial incentives, we can install solar systems at all district facilities, reducing our carbon footprint and saving millions of dollars over 40 years.

  1. Solar Power Savings Potential For 12.6 MW Installation • District enjoys a long history as a resource conservation leader ( early 1980’s DOE and CEC grants/loans, multiple performance contracts in the 1990’s and 2000’s, adoption of Energy Policy) • M and O staff began actively exploring the comprehensive installation of solar energy systems in 2008 • 2009 the District Applied for and was approved for $56 M in CREB’s (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

  2. 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

  3. 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 applications/reservations @ level 7 for 12.6 MW of solar system installation • Reservation requires a refundable deposit

  4. California Solar Initiative • Rebates for the installation of solar power • Based on the Watts installed/verified system performance • @ 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

  5. 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: http://www.eia.doe.gov/emeu/aer/elect.html

  6. 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

  7. 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 District’s 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
