SDG&E seeks CPUC approval of three long-term PPTAs for 450 MWs of electricity, estimated cost of just below $2 billion, to service their local service area. The PPTAs, if approved, are expected to be online by June 1, 2014.
Power Purchase Tolling Agreements ("PPTAs") are contracts to purchase power wherein the utility pays the seller a periodic payment for capacity for the length of the contract. The utility is responsible for the procurement and delivery of the fuel (e.g., natural gas) to the seller’s power plant generating units, and the scheduling of the generating units under contract. Hence, utility customers take all the upside and downside risks of fuel price volatility.
On May 18, 2012, DRA submitted testimony recommending that the CPUC reject the PPTAs because SDG&E did not demonstrate the need for 450 MWs for the 2011-2020 electricity procurement planning period.

A CPUC proposed decision is expected by the end of 2012.
