ISA Energia Brazil commissions Latin America’s first 460 kV vegetable oil reactor

• ISA commissioned Latin America’s first 460 kV shunt reactor using vegetable oil as insulating fluid at the Bauru substation in São Paulo, part of a grid modernization program.
• The project is backed by an investment of about USD 33 million and includes four high-capacity shunt reactors aimed at improving transmission reliability by absorbing excess energy that can lift voltage levels.
• Vegetable oil use is expected to cut the carbon footprint of materials by up to 20% and reduce lifecycle emissions by about 11%, while improving spill safety due to higher biodegradability.
• The initiative aligns with ISA’s net-zero target for 2050, with interim goals to cut emissions 60% by 2040 and 90% by 2050.
