Generally, efficiency increases along with turbine blade lengths. The blades must be stiff, strong, durable, light and resistant to fatigue. Materials with these properties include composites such as polyester and epoxy, while glass fiber and carbon fiber have been used for the reinforcing. Construction may involve manual layup or injection molding. Retrofitting existing turbines with larger bla.

The power station consists of three units, which went in service in 1966, 1967, and 1984, and generate 42 MW, 32 MW, and 50 MW of electric power (94 MW, 94 MW, and 152 MW of heat, respectively). The 101-metre-tall (331 ft) chimney at has a gallery that resembles an observation deck. However, it contains equipment for exhaust monitoring.

Flywheel 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 as a consequence of the principle of ; adding energy to the system correspondingly results in an increase in the speed of the flywheel. W.

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 friction and energy loss. First-generation flywheel energy-storage systems use a large flywheel rotating on mechanical bearings. Newer systems use composite
