We often hear about California's leading position in solar and latterly in energy storage. Perhaps lesser known than direct policy support for energy storage and renewable technologies is the way California's network operator (CAISO) is starting to reconfigure how it procures demand response, with a positive impact for energy storage - and particularly behind-the-meter assets, as Ted Ko, policy director of Stem, explains.

Navigant on energy storage as ‘non-wires’ alternative for utilities and grid operators

One of the ‘value of energy storage’ questions that was being asked a lot two or three years ago was around the use of batteries and decentralised system architecture instead of traditional “poles and wires” grid networks. However, advancements in this area have been slow to materialise and Navigant Research’s recent ‘Energy Storage for Transmission and Distribution Deferral’ report sought to fill the knowledge gap. Andy Colthorpe took the opportunity to ask lead author Alex Eller three quick questions around the topic.
