Recommendations for Further Study 1. Benchmark Alameda CCA Approach Against Existing CCAs. Over the past 6 years many communities have developed and implemented CCAs. As such,their experiences,strategies,and approaches to providing their customers with a cost competitive and cleaner energy alternative can be instructive. We do note,that such a comparison is NOT included in the Technical Study RFP and therefore was out of scope for the Study. However,we believe that such a comparison could be beneficial for the CCA advisory board as well as the individual municipal participants. 7 Estimate based on population and job growth between 2005 and 2010. 8 Estimate based on population and job growth between 2005 and 2010. 9 Direct Access(DA)electricity was likely over-estimated in 2005 inventory using County-wide DA data provided by the CEC.PG&E's 2010 electricity data shows that DA electricity use in Pleasanton is much smaller,and is negligible relative to overall usage. 10 High quality stationary source data for 2010 was provided by BAAQMD.This was unavailable for 2005 inventory and it is likely that stationary emissions were underestimated in 2005;however,the 2010 data may include some utility-provided natural gas which would be considered double-counting. 11 Includes power used for upstream water conveyance that occurs beyond the City limits,and indirect process and fugitive emissions from septic tanks and wastewater treatment processes.Note that indirect emissions from electricity used to convey water and wastewater within the City is included in Municipal Operations. 9
