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

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)


Current northwest energy issues

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)


Current northwest energy issues

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

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


What matters

What matters

  • Cost

  • Reliability of the system – keeping the lights on


Regional issues

Regional Issues

  • Federal Columbia River Power System BiOp

  • Northwest Power & Conservation Council

    • Fish and Wildlife Program Amendments

    • 7th Power Plan

      • Conservation and Energy Efficiency

      • Governor Inslee’s call for a coal-free energy system

  • State Renewable Portfolio Standards


Federal issues

Federal Issues

  • Columbia River Treaty

  • Federal Budget

    • Protect and defend

  • Department of Energy / BPA

    • Staffing

    • Standards

  • Federal Energy Regulatory Commission

    • Wind integration

    • Market

  • EPA
