Western leaders have long discussed creating a regional energy market, which would combine solar power from Arizona, wind from Wyoming, hydro power from Washington, and battery storage from California.
This shared resource would meet the demands of 11 states, supporting local power plants with surplus energy from across the region.
A new law in California has paved the way for this market to become a reality, with potential benefits including lower energy costs, a more resilient grid, and faster deployment of clean energy.
Proponents say it has the potential to lower energy costs, make the grid more resilient and speed up the deployment of clean energy.
The market's success depends on the participation of states and utilities, which is uncertain due to the increasing politicization of energy issues.
