These are some of the legal issues presented by ESS. Next, a brief introduction to ESS and their interface with renewable power plants is presented.
The systems are generally divided into two categories: large and small, although that size division usually places the devices into two other categories, upstream or downstream of the customer’s electricity meter. Large devices are upstream, and small ones are downstream.
Within each category, there are a number of technologies offered for sale or currently in development. These technologies include advanced batteries, ultra-capacitors, superconducting systems, high-speed flywheels, compressed air energy storage, pumped hydroelectric, pressurized hydraulic storage, among others.
Energy storage is a very timely topic, with many important ramifications for electric power consumers, power producers, utilities, state regulatory agencies, ESS manufacturers, and others. Each of the affected entities should obtain legal advice to assess their needs and opportunities in this growing, exciting, and important field.
