The state, which presently has various projects, is working to commercialize energy storage.
ISO CEO Steve Berberich said: "The roadmap is a foundation to integrate energy storage technologies that benefits grid reliability and consumers throughout the West."
In 2013, California mandated that investor-owned utilities must meet a combined target of 1.3GW of energy storage to be online by 2024.
CEC chairman Robert Weisenmiller said: "As we aim to further reduce greenhouse gas emissions and — by 2030 — get 50 percent of our electricity from renewable sources, flexible resources like storage will be important to balance the electric system.
"The collaborative effort of this roadmap will help by identifying barriers to energy storage technologies so we can keep our electricity supplies safe, affordable and reliable."
ISO said technology to store energy produced at low-demand times when demand increases plays an important role in optimizing the grid, rising renewable energy sources and reducing greenhouse gas emissions.
Batteries, flywheels, compressed air, thermal and pumped hydropower are currently being tested and marketed.
Various utilities have invested in storage projects, and have signed contracts for commercial potential in the future.
