California ISO
About Company
The California Independent System Operator (CAISO) manages the flow of electricity across 80% of California’s high-voltage power grid, ensuring reliable electricity delivery to 30 million Californians. It acts as an impartial grid operator, providing open access to the wholesale power market to diversify resources and lower prices, and granting equal access to extensive power lines. The CAISO’s role is similar to that of air traffic controllers, impartially managing the flow of electricity without owning the grid infrastructure itself.
