What is energy storage?
Energy storage is the capture of energy for use at a later time, and a battery energy storage system is a form of energy storage.
Battery energy storage has a variety of useful applications, such as balancing energy demand and supply for either the short or long term. This ensures the grid operates more efficiently. Plus, batteries are able to respond to changing supply or demand levels within a second.

Managing co-located projects: Turning hybrid complexity into performance
Across global renewables markets, hybrid and co-located projects are rapidly becoming the new standard. Pairing technologies such as solar and storage, or wind and storage, allows developers to maximise land use, improve grid stability and open up new revenue streams. The pace of adoption is accelerating, particularly in markets such…
