Railway electrification systems using alternating current (AC) at 25 kilovolts (kV) are used worldwide, especially for high-speed rail. It is usually supplied at the standard utility frequency (typically 50 or 60 Hz), which simplifies traction substations. The development of 25 kV AC electrification is closely connected with that of successfully using utility frequency. This electrification is ideal for ra. HistoryMany trial sites were developed at the beginning of the 20th century but developing a main frequency. .
Electric power for 25 kV AC electrification is usually taken directly from the three-phase . At the transmission substation, a step-down is connected across two of the three phases of the high. .
Railway electrification using 25 kV, 50 Hz AC has become an international standard. There are two main standards that define the voltages of the system: • EN 50163:2004+A1:2007 – "Railway application. .
The 2 × 25 kV system is a system which supplies 25 kV power to the trains, but transmits power at 50 kV to reduce energy losses. It should not be confused with the 50 kV syste. .
Systems based on this standard but with some variations have been used. In Japan, this is used on existing railway lines in , , and , of which Hokuriku and Kyush.

This is a list of energy storage power plants worldwide, other than pumped hydro storage. Many individual plants augment by capturing excess electrical energy during periods of low demand and storing it in other forms until needed on an . The energy is later converted back to its electrical form and returned to the grid as needed.
