Fourth Hekinan Thermal Power Station Unit Commences Commercial Operations

November 8, 2001

A fourth unit at the Hekinan Thermal Power Station, under construction since January 1998, commenced commercial operations today.
The Hekinan Thermal Power Plant is Japan's largest coal-burning thermal power station. When a fifth unit scheduled for completion in November 2002 is operating, Hekinan will generate a total of 4.1 million kW of electricity.
The new fourth unit at Hekinan brings the total electrical power generating capacity of Chubu Electric Power to 32,898,530 kW.
Chubu Electric Power will continue to develop new power sources to ensure a stable and economical power supply, while working to maintain an optimum balance of thermal, hydroelectric, and nuclear power sources.

2 Features

  1. (1) Environmental protection

Chubu has installed high-performance emissions systems on the fourth and fifth units, as well as improving the performance of existing units one through three. Chubu aims to keep the total nitric oxide, sulfate, and soot emissions of all five units at the same levels as those emitted by Nos. 1-3 when they commenced operation.

  1. (2) Lower costs and more efficient construction techniques

While constructing the fourth and fifth units at Hekinan, Chubu worked to reduce costs without compromising their high standards of quality. This was accomplished by introducing competitive bidding for purchasing equipment. Chubu required prospective suppliers to submit proposals and adopt more efficient construction techniques, including the use of large block construction for machinery installation.

  1. (3) Use of supercritical high-pressure 1 million kW generating facilities, exclusively for coal-burning generator

The facility will be extremely efficient (energy efficiency: minimum 42%) and reliable by using state-of-the-art technology, including the world's first 1 million kW single-shaft turbine generator * (3600 rpm).

  1. (4) Advanced automation

A minimal number of personnel are needed in the central control room to operate and monitor the generating facilities from startup to shutdown.
The system features centralized monitoring and controls, a server that administers and monitors the entire operation for extra reliability, and a function-distribution system with control devices for each piece of equipment.
  • *A single-shaft turbine generator is comprised of high, medium, and low-pressure turbines and generators connected in series on a single shaft.
