Chiba Thermal Power Station, is an operational thermal power station located in the city of Chiba, Japan. It is owned and operated by JERA, with a maximum output of 4380 MW. Originally built in the late 1950s as a coal-burning plant, it was later converted to a plant burning liquefied natural gas in 2000.[1][2]
History
Chiba Thermal Power Station began operations in the late 1950s as a 600MW capacity coal fired power plant. It had four units however due to aging facilities and increasing demand for electricity, in 2000 the plant was renovated to a combined cycle power plant and fuelled with Liquefied Natural Gas (LNG). Groups 1 and 2 were constructed in 2000 with a maximum output of 2880 MW. In 2011, as part of an emergency plan to supply power after the Great East Japan Earthquake, three gas turbine systems were constructed within 4 months. From 2012 to 2014, a more advanced combined cycle system was added as group 3. This added an additional 1500MW capacity.[2]
Power generation
When Chiba Thermal Power Station was renovated to a combined cycle power plant, Groups 1 & 2 were constructed. Each has a total power output of 1440 MW. Group 3 was constructed outdoors, as opposed to indoors like Groups 1 and 2, due to the need for it to be built quickly after the Great East Japan Earthquake. Group 3 added a power output of 1500MW. The total power output of the station is 4380MW and the site covers approximately 760,000 square metres of land.[2][3] LNG is supplied by pipeline from terminals located at Sodegaura Power Station and Futtsu Power Station and the plant outputs its cooling water into the nearby sea.[4][5]
| Operation Started | Power Generation Type | Design Thermal Efficiency | Output | Total Output | |
|---|---|---|---|---|---|
| Group 1 | April 2000 | ACC | 54.2% | 360MW x 4 | 1440MW |
| Group 2 | June 2000 | ACC | 54.2% | 360MW x 4 | 1440MW |

Historic power generation
Group 1 of the original coal-fired power station began operations in April 1957, and in following years more groups were added, ending with Group 4 in November 1959. Originally burning coal, the plant later switched to crude oil. Due to aging facilities and the increasing demand for electricity, in 2000 the plant was renovated and a new combined cycle power generation system was installed (see above).[2]
