The document discusses SMUD's renewable energy goals and plans to acquire concentrating solar thermal (CST) power. SMUD aims to source 20% of its electricity from renewables by 2010 and 33% by 2020. CST could provide a significant portion of these targets, with the equivalent of 1000 MW by 2010 and an additional 735 MW by 2020. SMUD issues requests for renewable energy offers and may negotiate power purchase agreements for emerging technologies like CST. CST with storage is presented as a good fit for SMUD's needs because it can generate power when demand is highest in the daytime and evenings.
