CA ISO Explains the Need for Energy Storage

By Ares North America on Nov 05, 2013 at 02:11 PM in ARES News

The electric grid and the requirements to manage it are changing. Renewable resources increasingly satisfy the state’s electricity demand. Existing and emerging technology enables consumer control of electricity consumption. These factors lead to different operating conditions that require flexible resource capabilities to ensure green grid reliability. The ISO created future scenarios of net load curves to illustrate these changing conditions. Net load is the difference between forecasted load and expected electricity production from variable generation resources. In certain times of the year, these curves produce a “belly” appearance in the mid-afternoon that quickly ramps up to produce an “arch” similar to the neck of a duck—hence the industry moniker of “The Duck Chart”.

In three years, a fleet of automated 300-ton electric-traction-drive shuttle trains should be moving up and down a 7.2% grade slope in the mountains of Nevada. The ‘Advanced Rail Energy Storage’ (ARES) ancillary services system could provide 50MW of fast response power to help stabilize the California electricity grid.
