Utility-owned distributed photovoltaics systems

The potential for PV as a utility service option to customers and for Pacific Gas & Electric Company´s (PG&E´s) own internal operations applications is examined. The cost of PV power is compared to that of line extensions for customers with remote power requirements. Key factors that influence a utility´s decision to install PV for distributed applications are discussed. Preliminary findings show that many remote sites, perhaps several thousand, exist within PG&E´s service territory where stand-alone PV power generation is technically feasible and the most economically competitive power source. PV could also have a significant impact on PG&E when used for dispersed grid-connected applications within the utility´s electrical distribution system.
