Medway Power Station

Medway Power Limited (MPL) was incorporated in September 1990. It is a joint venture company originally comprising Arlington, Virginia-based AES Corporation (trading as AES Electric) (25%) and the RECs SEEBOARD (37.5%) and Southern Electric (37.5%) (became SSE in 1998). In April 1992 MPL awarded a design, procurement and construction contract to a consortium of Europower Development Ltd and TVB Power Ltd. The contract called for a turnkey 660 MW combined cycle electricity generating plant, deliverable by 1 August 1995. The station was built by Marubeni (Japanese), Tarmac and Kansas City-based Black & Veatch. The station is run by Scottish & Southern Energy under the name Medway Power Ltd. It was commissioned in 1995, being . In June 2002, American Electric Power (AEP) sold its SEEBOARD company to eDF, giving eDF 37.5% of the power station. SSE bought the plant from AES and eDF Energy for £242m on 3 October 2003. It is near (west of) to the Grain Power Station and next to the Thamesport. == The Site ==

The station is on an 11 acre (4.45 ha) site, above the 200 year flood plain. There is a requirement that the noise at the perimeter must not exceed 65 dBA. The three turbines are contained within an acoustic enclosure in a containment building. The two exhaust stacks are 65 m tall. Stack emissions are limited to 45 ppm NOx. Cooling water is abstracted from the Medway and chlorinated. Water discharges are monitored and treated prior to discharge. ==Specification==

Medway power station is a CCGT-type power station that runs on natural gas. It has two General Electric Frame 9 (9001F) gas turbines. The exhaust gas from these reaches two Nooter Eriksen heat recovery steam generators. The steam from these powers one General Electric steam turbine. Main plant The operating parameters of the main generating plant are as follows. During a major upgrade project in 2012 the power station benefitted from the GE DLN 2.6 install as well as an upgrade to the excitation and turbine control system. Currently the power station operates as a two-shifting plant with approximately 20MW of black start capacity. Ancillary plant Specification of the ancillary plant is as shown in the table. ==See also==
