Southern California Edison (SCE) installed a 10 MW battery energy storage system (BESS) at its Chino substation facility in 1988. The BESS facility has been in operation for six years and has been used for load leveling and peaking functions. The BESS power conversion system was built with the then state of the art technology and has a very fast
Delivering the energy storage technologies to enable a secure, carbon free electricity system on the island of Ireland by 2035. Our mission // We engage with stakeholders on behalf of our members to ensure that policy and market design supports the efficient development of energy storage for the benefit of consumers in Ireland & Northern Ireland.
Substations contain the specialist equipment that allows the voltage of electricity to be transformed (or ''switched''). The voltage is stepped up or down through pieces of equipment called transformers, which sit within a substation''s site. Transformers are electrical devices that transfer electrical energy by means of a changing magnetic
