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 1960s to 1980s,.

Like a savings account for the electric grid, energy storage neatly balances electricity supply and demand. When energy generation exceeds demand, energy storage systems can store that excess energy until electricity production drops and the energy can be deposited back to the power. . Inertia in power systems refers to the energy stored in large rotating generators and some industrial motors, which gives them the tendency to remain rotating. This stored energy can be particularly valuable when a large power plant fails, as it can temporarily make up for the power lost from the. . Inertia is the grid's resistance to frequency changes; batteries with smart inverters can synthetically create it. Renewable generation differs from traditional generation in many ways.
