PNWA Summer Meeting

June 23, 2014

bpa customers
BPA Customers
  • Consumer owned, not-for-profit utilities who buy electricity from the Bonneville Power Administration
  • A legal and historic first right to federal power at cost
    • Electric Cooperatives
    • Public Utility Districts
    • Municipal Utilities
    • Tribal Utilities
    • * Direct Service Industries
take aways
Take-aways
  • The electrical system must reliably provide power to keep the lights on
    • Power is provided by generating capacity
  • Generator output must exactly match demand for electricity every 4 seconds
    • Need flexible/controllable generation
  • Interconnected power systems create opportunities and risks

Let’s talk generators

Electricity

Steam turbine - generator

Hydro turbine - generator

generator capacity
Generator Capacity
  • A generator can produce power up to its nameplate capacity – power output
    • Actual power output depends on generator type, fuel availability, etc.
  • Power output is measured in Watts
    • kW = 1,000 watts, MW = 1,000,000 Watts
hydro
Hydro

Flexible and controllable (with lake storage)

Coal

Boardman Coal Project, OR

Thermal - Generally fixed with some control (with coal pile storage)

natural gas
Natural gas

Rathdrum Power Project, ID

Thermal - Flexible and controllable (limited by pipeline capacity)

nuclear
Nuclear

Columbia Generating Station, WA

Thermal - Generally fixed with minimal control (long term fuel storage)

geothermal
Geothermal

Raft River Geothermal, ID

Thermal - Generally fixed with minimal control (no fuel storage)

slide14
Wind

Nine Canyons Wind Project, WA

Intermittent with minimal control (near term predictability with no fuel storage)

Known as Variable Energy Resources (VERS)

solar p hoto v oltaic or pv
Solar PhotoVoltaic, or PV

Follows Sun with minimal control (no fuel storage)

Also known as Variable Energy Resources (VERS)

landfill gas to electricity
Landfill gas-to-electricity

Coffin Butte Landfill Gas Project, Corvallis OR

Thermal - Fixed output with some control (no fuel storage)

electrical system
Electrical System

Simple system:

Ignores losses & voltage transformations

100 MW

Generation must match Load

Every 4 seconds!

100 MW

interconnected systems
Interconnected systems
  • Created hourly markets
    • Market opportunities and risks
      • Economic gains / losses
  • Exposure to reliability risks
    • That’s why a power line fault in Idaho can cause an outage in San Francisco
    • Complexity
