1 Current Northwest Energy Issues A BPA Customer Perspective Dan James PNWA Summer Meeting June 23, 2014

2 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

3 PNGC Power Members

4 Power Systems 101

5 Take-aways 1.The electrical system must reliably provide power to keep the lights on –Power is provided by generating capacity 2.Generator output must exactly match demand for electricity every 4 seconds –Need flexible/controllable generation 3.Interconnected power systems create opportunities and risks

6 Let’s talk generators Hydro turbine - generator Steam turbine - generator Electricity

7 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

8

9 Hydro Flexible and controllable (with lake storage)

10 Coal Thermal - Generally fixed with some control (with coal pile storage) Boardman Coal Project, OR

11 Natural gas Thermal - Flexible and controllable (limited by pipeline capacity) Rathdrum Power Project, ID

12 Nuclear Thermal - Generally fixed with minimal control (long term fuel storage) Columbia Generating Station, WA

13 Geothermal Thermal - Generally fixed with minimal control (no fuel storage) Raft River Geothermal, ID

14 Wind Intermittent with minimal control (near term predictability with no fuel storage) Known as Variable Energy Resources (VERS) Nine Canyons Wind Project, WA

15 Solar PhotoVoltaic, or PV Follows Sun with minimal control (no fuel storage) Also known as Variable Energy Resources (VERS)

16 Landfill gas-to-electricity Thermal - Fixed output with some control (no fuel storage) Coffin Butte Landfill Gas Project, Corvallis OR

17 Electrical System 100 MW Simple system: Ignores losses & voltage transformations Generation must match Load Every 4 seconds!

18 Nuclear Coal Natural Gas Morning peak Evening peak Wind Ramp

19 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

20 Take-aways 1.The electrical system must reliably provide power to keep the lights on –Power is provided by generating capacity 2.Generator output must exactly match demand for electricity every 4 seconds –Need flexible/controllable generation 3.Interconnected power systems create opportunities and risks

21 What matters Cost Reliability of the system – keeping the lights on

22 Regional Issues Federal Columbia River Power System BiOp Northwest Power & Conservation Council –Fish and Wildlife Program Amendments –7 th Power Plan Conservation and Energy Efficiency Governor Inslee’s call for a coal-free energy system State Renewable Portfolio Standards

23 Federal Issues Columbia River Treaty Federal Budget –Protect and defend Department of Energy / BPA –Staffing –Standards Federal Energy Regulatory Commission –Wind integration –Market EPA
