- Batang Ai Dam- 4 x 25 MW = 100 MW.
Thermal power plants
There are 35 thermal power plants and diesel-electric plants with installed generating capacity of 650 MW in operation. Selected major plants are:
- Kuching power station, Kuching - xx MW
- Miri power station, Miri - xx MW
- Bintulu power station, Bintulu- xx MW.
- Sejingkat power station, Kuching- 2 x 55 MW = 110 MW, coal fired power station (phase II)
A notable aspect of SESCO operation is the many small diesel-electric power plants in isolated areas, some supplied by air at prohibitive cost.
