Barito Renewables Subsidiary Wins PROPER Gold Award for Environmental Excellence
A subsidiary of Barito Renewables Energy Tbk (BREN), through Star Energy Geothermal via Star Energy Geothermal Wayang Windu Ltd (SEGWWL), has secured the prestigious PROPER Gold Award from the Ministry of Environment and Forestry (KLH). The recognition highlights outstanding environmental performance that exceeds regulatory compliance while delivering sustainable social benefits.
President Director of Barito Renewables Energy and Group CEO of Star Energy Geothermal, Hendra Soetjipto Tan, emphasized the company’s commitment to responsible, eco-friendly, and sustainable operations. He noted that continuous innovation remains key to improving efficiency and maximizing community impact.
The PROPER Gold Award was achieved by the Wayang Windu geothermal power plant located in Pangalengan, driven by several key innovations. One major initiative, the WW Retro program (cooling tower retrofit for units 1 and 2), successfully reduced energy consumption by 31,622.4 GJ.
In terms of emissions reduction, the PACE WW (smart cooling system) program significantly cut greenhouse gas emissions by up to 1.75 million tons of CO₂ annually. Additionally, the ASIS TURBO program (Artificial Oil & Sweetening System) improved hazardous waste management by reducing used oil in turbine operations.
Meanwhile, two other geothermal assets—Salak in Sukabumi and Darajat in Garut—earned PROPER Green ratings, reinforcing the company’s strong environmental commitment and social responsibility.
With a total installed geothermal capacity of 926 MW across its assets, Barito Renewables Energy stands among the largest geothermal portfolio holders. By the end of 2026, the company is projected to operate 1 GW of geothermal capacity alongside 79 MW of wind power, further strengthening its position in the renewable energy sector.
