Facilities for a Stable Supply of Electricity
TEPCO generates electricity at hydro, thermal, nuclear and renewable energy stations, with this electricity passing through transmission lines, substations, distribution lines, and other equipment before reaching our customers.
Power Transmission Lines
Power transmission lines function to deliver electricity from distant power stations to our customers.
These lines are for transmitting large amounts of electricity in a stable and efficient manner.
Substations control voltage in order transmit high-quality electricity with little loss.
There are 1,614 substations within the TEPCO Power Grid’s service area (as of end of March 2017) that perform functions such as voltage step-up/step-down and frequency regulation.
Distribution lines serve as the final paths through which electricity reaches our customers from remote power stations.
These well-known facilities ensure a stable supply of electricity with a suitable voltage for our customers.
Communication lines are power transmission equipment used for information transmission in order to provide a stable supply of electricity by adjusting the output of power stations and other facilities, and controlling power facilities in order to achieve a balance between the supply and demand of electricity.
