The development and construction phase of the Geothermal Power Plant (GPP) was began in March 2017, and the generated electricity is channeled through the 150 KV High Voltage Transmission Line (SUTT) and connected to the Sumatra electricity toll road network owned by PT PLN (Persero) based on a 30-year Power Purchase Agreement. To develop this GPP project, PT SEML appointed a consortium of Sumitomo Corporation and Rekayasa Industri (Rekind) as EPC contractor. The main equipment of turbine and generator is produced by Fuji Electric.

The construction of the Muara Laboh GPP has helped South Solok Regency in particular, and the Province of West Sumatra in general, through various integrated social development programs, employment opportunities for around 1,200 local workers, and providing business opportunities for local entrepreneurs during its 30-month construction period. In addition, sustainable and environmental friendly electricity generated by this GPP is able to supply electricity to around 340.000 households.
