Background on Plant

The power station was opened in March 1987 by then Sultan of Selangor, Sultan Salahuddin Abdul Aziz Shah, and the station was named after him. In terms of power producing capacity, it is one of the largest power stations in Malaysia. It was also the first coal-fired power plant in the country. In addition to its four coal-fired units generating 1,600-MW, the station has units firing gas and bunker oil.

Kapar Energy Ventures Sdn Bhd is a joint venture company between Tenaga Nasional Berhad (TNB) and Malakoff Berhad, with an equity holding of 60% TNB and 40% Malakoff Berhad. Kapar Energy Ventures Sdn Bhd (KEV) owns, operates and maintains SSAAPS since July 9, 2004, after successful acquisition of the power plant from TNB.

The plant was designed by Minconsult, a Malaysian engineering consultancy.

The power station's toxic ash pond is allegedly a sanctuary for migratory birds that stop over en route from Siberia to Australia.

Planned retirement

In February 2020 and March 2021, Malaysia's Suruhanjaya Tenega (Energy Commission) released generation development plans covering 2020-30 and 2021-39. Additional background is available at the Unnamed Malaysia coal projects wiki.

The plans forecast retiring the Sultan Aziz power station (KEV Coal U3-U6 and KEV Gas U1 & U2) in 2029. (One plan listed the coal power station units as 1,474 MW in capacity and the other as 1,486 MW coal capacity.)[3][4][5]
