PGE Renewable Power
The Costs of Change
The Power to Make a Difference
• Who & What we do
• Where we are today & where we came from
• What are renewables & examples
• PGE System mix and Carbon
• Transmission Costs
• Carbon Costs
• Development Costs
Fast Facts on PGE’s Renewable Program
Almost 67,000 customers enrolled!
Customer satisfaction increased among
customers who know about the program
Working with Green Mountain to help market &
supply options to customers
Customers choose to pay a small premium for renewable energy
PGE’s renewable program is 1st in
the nation for residential
“green” power sales
Oregon helps lead the way for renewable power
• PGE ranked 1st nationally for residential kwh (2007)
• PGE ranked 2nd nationally for all customers kwh
• PGE ranked 1st in NW for participation rate – 8.5%
• Pacific Power also ranked highly in nation and NW
Oregon helps lead the way for renewable power
• PGE renewable customers Dec. 2001: ~ 4,900
• July. 2008: ~ 66,129
• PGE has almost 10% of all renewable power customers nationwide
What is renewable power?
• Energy from sources that naturally replenish– Wind, Solar, Geothermal, Low-Impact Hydro, Biomass
• Low environmental impact
• Doesn’t deplete natural resources
PGE renewable power types
• Wind power:– Wind spins blades
that turn a generator
• Biomass energy:– Combustion of wood
waste creates steam that spins turbines turning a generator
PGE renewable power types
Biomass (conversion of biological materials)
• PGE “BioGas”– Methane from cow manure burned to
run generator
– Methane is 20X more harmful as greenhouse gas than the CO2 created when it burns
– 220,000 kwh a year from CalGon Farms, Salem
– BioGas power mixed with renewable power sold to large commercial- industrial customers

PGE renewables environmental impact
• Offsets since 1999 ~ 1,000,000,000 lbs of CO2
• Offsets other thermal power plant emissions and impact on fish at hydro plants
Transmission Costs in our Future
• For Wind in the NW from East to West and to the South into CA
• For Concentrated Solar Power projects in the SW in remote desert locations to population centers to the SW and the West Coast
• Inland from Tidal and Wave projects to the East
Determining the True “Costs” of Carbon
• Cap and Trade to start: will mandate higher energy costs
• Impacts from higher carbon costs will be regional, some areas pay more some pay less.
• Costs of future carbon legislation to deal with non-linear effects from Climate Change
Development Costs
• Costs of developing cost effective wave and tidal power generation
• Costs for perfecting fuel supplies for biomass projects
• Costs for development of a “Smart Grid’ to facilitate development of distributed renewable generation
Investing in the Future
• The costs are high and may be getting higher but the returns are real
