The service life of grid energy storage equipment

Electricity can be stored directly for a short time in capacitors, somewhat longer electrochemically in , and much longer chemically (e.g. hydrogen), mechanically (e.g. pumped hydropower) or as heat. The first pumped hydroelectricity was constructed at the end of the 19th century around in Italy, Austria, and Switzerland. The technique rapidly expanded during the 196. Some BESS components (e.g., transformers) have a much longer lifespan than batteries and can thus be reused. Alternatively, a BESS developer may design the system to last 25-35 years and replace the batteries when they begin to fail.
