State-owned electricity monopolist PLN has pledged to become carbon neutral by 2050 with a plan to phase out fossil fuel-fired power plants and use more renewable energy in its networks.

PLN president director Zulkifli Zaini said the company was planning to develop new solar and wind power plants, mix biomass with coal – so-called co-firing – in existing coal plants and convert diesel-fired power plants to renewable energy-based power plants.

“After we finish developing the 35,000 megawatts [of additional power generating capacity], we will fulfil Indonesia’s electricity needs using only renewable energy,” Zulkifli said in an online briefing on Friday.
