On 5 July, KOMIPO and Doosan Heavy Industries & Construction signed a contract for the latter to supply key parts for two new complex fuel generators to be built in the subterranean space of the Seoul Thermal Power Plant in Mapo.

The generators, worth KRW 1.18tn (USD 1bn) and capable of producing 800MW, will be the world’s first-ever fully underground power generating facility, according to officials.

Doosan HIC is to provide for components such as gas turbines, steam turbines and heat recovery systems, worth KRW 360bn in total.

The superstructure of the underground facility will be used as an urban park area for residents, officials also said.

"Underground plant construction, though 1.5 times more expensive than conventional aboveground construction, is an effective use of the limited urban space," said a KOMIPO official.

The blueprint was modeled after Tate Modern, the famous power plant-turned-museum in London, he added.
