Super Thermal Power Stations (STPS) or Super Power Station are a series of ambitious power projects planned by the Government of India.
 With India being a country of chronic power deficits, the Government of India has planned to provide 'power for all' by the end of the eleventh plan.
The capacity of thermal power is 1000 MW and above.
 This would entail the creation of an additional capacity of at least 100,000 Megawatts by 2012.
 The Ultra Mega Power Projects, each with a capacity of 4000 megawatts or above, are being developed with the aim of bridging this gap.
