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 grid would meet the demands of 11 states, supplementing local power plants with excess 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 accelerated clean energy deployment.
Proponents say it has the potential to lower energy costs, make the grid more resilient and speed up the deployment of clean energy.
However, the market's success relies heavily on the participation of states and utilities.
