The purpose of the 2009 CSI Impact Evaluation (June 2010, 8 MB) study is to assess the impact of the CSI program during the 2009 timeframe. This includes not only CSI solar systems installed during calendar year 2009, but also systems installed in 2007 and 2008 that were operational in 2009. Similar to the 2007-2008 CSI Impact Evaluation Report, the 2009 CSI Impact Evaluation Report examines the impacts of the CSI program on electricity energy production and peak demand reduction, performance relative to installed capacity, expected versus actual solar production, emissions reductions (CO2, NOx, PM-10), and transmission and distribution
system impacts. In addition to the objectives of previous CSI reports, a primary objective for this report is to assess the extent to which the CSI participants have undertaken energy efficiency measures as a result of the energy audit required by the CSI program and to determine the level of integration between energy efficiency and solar. The research team also conducted billing and load profile analyses to further evaluate the impact of the CSI program on customer utility bills.
Key objectives addressed in the 2009 CSI Impact Evaluation evaluation include:
- Impacts on electricity energy production and demand reduction
- Performance relative to installed capacity
- Expected vs. actual solar production
- CO2, NOx, and PM-10 emissions reductions associated with the solar installations
- Transmission and distribution system impacts
- Energy use and daily energy profiles of CSI participants.
- Monitoring and maintenance impacts on PV performance
- Energy efficiency adoption and impacts of CSI participants
- Awareness and satisfaction of the CSI program and future opportunities
