The geothermal plant construction will require drilling of twenty-two wells. Through those, hot water from volcanic rocks will be supplied to a separator, where it will fall into steam and water. The steam will then be fed to two turbines with a total capacity of 220 megawatts (MW), and water will be pumped back into the rock. The power plant will generate 1,730 gigawatt-hours (GWh) of electricity per year, equivalent to 0.5% of Indonesia’s power demand. The public grid PT PLN (Persero) will purchase generated electricity for thirty years at a price of $0.094 per kilowatt hour (kWh), which is comparable to the cost of electricity for industrial consumers in the United States ($0.086 per kWh, according to the US Department of Energy).

According to Ember, in 2021, the share of geothermal sources in Indonesian power generation structure was 5.2% (while coal, gas and oil products accounted for 81.8%, and all other sources, for 13%). Geothermal electricity is generated by 31 turbines with a total capacity of 2,074 MW. Indonesia ranks second in the world in terms of total geothermal capacity, surpassed only by the United States (2,762 MW). In its turn, it surpasses Philippines (1,590 GW), New Zealand (926 MW) and 13 other countries, including Iceland (733 MW).

According to Global Energy Monitor, by January 2023 the global capacity of existing geothermal plants reached 11,786 MW, and the capacity of the plants under construction, 843 MW. In the coming years, the development of this energy sector will be driven by the use of technologies in the oil and gas industry, including horizontal drilling and distributed fiber optic sensing, which makes it possible to obtain information about underground soil layers. American Fervo Energy will apply these technologies in the construction of geothermal stations in Utah and Nevada, where geysers lie at depths exceeding 6 km.

Indonesian PT PLN Nusantara Power, the subsidiary of the state-owned energy distributor Persero, announced the tender for building a 100 MW floating solar power station (SPP). The Karangkates project will be implemented at the water reservoir of the dumb with the same name on Java Island.

The new floating SPP is not the first one for PLN Nusantara Power. In November 2022, they brought on stream the Cirata 145 MW above-water photovoltaic plant, which they built jointly with Masdar (UAE) specialising in renewable energy generation. In addition to supplying energy to 50 thou households, the power plant will help to save 214 Kt of greenhouse gases per annum, which is compatible with 6% of annual emissions from flaring associated petroleum gas in the territory of Indonesia.

According to Ember research centre, the cumulative capacity of all the SPPs in Indonesia by the end of 2021 achieved 210 MW; however, they account only for 0.1% of electricity generation in the country. The main volumes were generated by coal-fired (61.5%) and gas-fired (18.2%) power plants, as well as diesel generators (2.2%). Hydro power plants (8%) and biomass-based plants (4.9%) prevailed among the renewable energy sources, and the share of all other RES including floating SPPs made составила 5.2%.
