Technology Marketing Summary

Grid Friendly™ Charger Controller or Grid Friendly™ Appliance technology, both developed at Pacific Northwest National Laboratory (PNNL), provide regulation services for utilities based on varying loads by water heaters and electric vehicle chargers.

Description

With increased levels of wind and solar power on the electrical grid, utilities are finding it more difficult to predict their power generation capabilities. At the same time, utilities need regulation resources to counteract the expected minute-to-minute shortages and overages in power generation to meet demand. Historically, these resources have been provided through hydropower and natural-gas powered generators.

Today, researchers at Pacific Northwest National Laboratory have invented a way to use grid frequency information to inform smart appliances and devices of how to adjust their operations (i.e. decrease increase demand) to provide regulation services. These devices measure grid frequency directly from a wall outlet while meeting consumer-set objectives, such as charging an electric vehicle’s battery by a certain time of day or maintaining a water heater’s temperature.

The algorithms used in this regulation tool allow the U.S. electrical grid to maintain its standard frequency of 60 Hertz. The result is less power fluctuations that require the start up or shut down of conventional generators to compensate, thereby increasing emissions and reducing wear and tear on the generators.

Benefits
  • Reduced generator maintenance costs (due to less wear and tear from start and shut-down operations).
  • Less emissions from generators
