Bonneville Power Administration is our energy provider. If you’d like to see a real-time look at electricity generation on their system, visit this graph on their website.

  • The red line shows the amount of electricity being used by their customers.
  • The blue line is the amount of electricity being generated by the hydropower system.
  • The green line is the amount of electricity being generated by wind farms.
  • The brown line is the amount of electricity being generated by other resources, such as geothermal, gas, coal, and nuclear plants.

Because the BPA also sells electricity to other regions, the total generation in the region almost always exceeds the amount of electricity being used by BPA’s customers.

Nuclear power, natural gas wind and coal generation make up the remaining 15% of our existing power supply. As demand for electricity grows, more resources must be built.
