The California Independent System Operator (ISO), the California Public Utilities Commission (CPUC) and the California Energy Commission (CEC) unveiled a comprehensive roadmap to assess the current market environment and regulatory policies for connecting new energy storage technology to the state's power grid. Technology to store energy is vital to optimizing the grid, increasing renewable energy sources and reducing greenhouse gas emissions. The top concerns of industry stakeholders are implementing a process for promoting existing products and driving new ones to market; understanding and addressing connection of storage devices to the grid; and reducing costs and setting up fee structures for the new technology.
