An effort is underway to explore adding fast-acting energy storage into traditional hydroelectric units to improve response and stability, and to increase operational flexibility, particularly when integrating renewable power.
Warmer, wetter winters and hotter, drier summers seem likely to be the new normal as the result of climate change, and dam operators need to be ready.
If the effects of global climate change play out as expected in the Pacific Northwest, the changing water supply will challenge dam operators to provide reliable hydropower while protecting fish.
Two new small hydropower plants located on creeks above Snoqualmie Falls will will provide power during the high-demand winter months and add carbon-free electricity to the power supply of the Snohomish County Public Utility District.
Understanding the potential revenue streams from a specific pumped-storage hydropower project within the region would go a long way toward making pumped-storage a competitive option for future consideration and development.
Snowpack is good for hydropower this year, but some areas are flooding
