May 29, 2025: RGE and TotalEnergies are to develop, build and operate a utility-scale solar-BESS facility in Indonesia’s Riau Province.

The firms have entered into a co-investment agreement through their equally-owned joint venture Singa Renewables.

The deal was signed in Indonesia on May 28 in the presence of the country’s president, Prabowo Subianto, and French president Emmanuel Macron.

Financial and technical details of the plant, which will be built in two phases, were not disclosed.

However, Helle Kristoffersen, TotalEnergies’ Asia president and executive committee member, said the project would support development of regional renewable energy infrastructure and advance the wider ASEAN region’s power grid development.

The plant is expected to become a significant energy supplier for domestic consumption and also export energy to Singapore.

RGE, a global group of companies in the bio-based resources and energy sectors, is headquartered in Singapore. TotalEnergies owns French battery manufacturer Saft.

TotalEnergies announced earlier this year that it was investing €160 million ($173 million) in six new battery energy storage projects in Germany.

Last February, Indonesian nickel producer Merdeka Battery Materials said it had secured a $1.4 billion loan for construction of a chemicals processing plant in the country.

The company said the loan would help finance the building of a high-pressure acid leach (HPAL) plant, in the Indonesia Morowali Industrial Park, to produce nickel or cobalt chemicals as part of the EV battery production process.
