Utilities, or in other words Front-of-the-Meter applications, is one of the main business segments of energy storage and it differs significantly from the C&I business area. Utility-scale energy storages are typically large energy storage systems with a capacity of tens or even hundreds of megawatts. Large renewable energy production plants, such as solar and wind farms, already generate a significant share of the energy consumed by today’s societies.
Unlike traditional fossil energy production, wind and solar power plants cannot regulate their production according to consumption, but produce energy depending on the day, season, and weather conditions. This is often not congruent with instantaneous energy consumption, which requires a tool that flexibly stores the produced energy and transfers it to a time when there is no renewable production but even more consumption. Utility-scale energy storages also play an essential role in enabling the smooth operation of the electricity grid as they balance the frequency and voltage of the electricity grid by supplying and withdrawing energy from it, thus keeping the amount of energy in the grid in balance with consumption. In addition to smart control technology, these large energy storage systems are all about optimizing the amount of energy for the used footprint.
