First-generation flywheel energy-storage systems use a large steel flywheel rotating on mechanical bearings. Newer systems use carbon-fiber composite rotors that have a higher tensile strength than steel and can store much more energy for the same mass.OverviewFlywheel energy storage (FES) works by spinning a rotor () and maintaining the energy in the system as . When energy is extracted from the system, the flywheel's rotational speed is reduced a. .
A typical system consists of a flywheel supported by connected to a . The flywheel and sometimes motor–generator may be enclosed in a to reduce fricti. .
Compared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no maintenance; full-cycle lifetimes quoted for flywheels range from in excess of 10 , up to 10 , cycles.

In 2021, Switzerland's photovoltaic (PV) installations increased to 685 MWp from 475 MWp in 2020. The Federal Energy Act, revised and effective from January 1, 2018, changed the support scheme for PV systems: it extended the one-time investment subsidy to all sizes of PV systems, ranging from 2 kW to 50 MW. Additionally, in 2022, the investment subsidy formula was updated to encourage investments in larger PV capacities and more efficient use of rooftop space.
