Tribal Concerns/Project DriversTribal Concerns/Project Drivers
The Tribe Has Several Concerns Regarding Energy Supply
Electric Rates (Price and Stability)
Electricity Reliability
Energy Independence
Local Control
Environmental Impacts
Viejas and Black & Veatch Have Cooperated on Energy Investigations Since 2001

Past Work: Energy Assessment and Utility Formation Studies (2001, 2002)Past Work: Energy Assessment and Utility Formation Studies (2001, 2002)
Conclusions of Previous Work:
Largest costs and risks involved with forming a utility are associated with:
Procurement of electricity from the volatile California energy market
Transmission of purchased power to the reservation
Local renewable energy resources could address these issues
