Chilean Company Creates Safer Battery Storage Conductors

Battery fires could become a thing of the past thanks to a new safety solution developed in Chile.

COVISA, a Chilean electrical conductor manufacturer based in Viña del Mar, has created COVIBESS, specially designed cables for battery energy storage systems that prevent dangerous thermal runaway events. These chain reactions can trigger fires, explosions, and toxic gas releases in the massive battery installations that store renewable energy.

The timing couldn't be better. Chile's renewable energy boom has created urgent demand for safe battery storage solutions, especially in mining operations, data centers, and solar farms where power reliability means everything.

COVIBESS tackles the problem at its source. The cables are halogen-free and designed to resist flame spread, self-extinguish during incidents, and minimize toxic emissions if accidents occur. This protects both workers and the sensitive electronic equipment that keeps industrial facilities running.

"The expansion of battery storage systems is raising the requirements for all associated electrical infrastructure," explains Carlos Vásquez, COVISA's commercial manager. "Today it is no longer enough just to store energy. It is also essential to ensure that its transmission is safe, reliable, and ready to operate under highly demanding conditions."

The company manufactures the conductors using 100% renewable energy, adding another environmental win to the safety benefits. COVIBESS has earned both SEC certification and CESMEC Category A certification, positioning it as one of Chile's most advanced solutions for critical energy infrastructure.

The Ripple Effect

COVISA's innovation shows how Chile's energy transition is creating opportunities for domestic manufacturers to compete globally. Founded in 1977, the company has evolved from a regional cable maker into a developer of cutting-edge safety solutions for Latin America's booming renewable sector.

The battery storage market across Latin America is exploding as countries race to integrate solar and wind power into their grids. Between November 2025 and April 2026 alone, multiple major battery storage projects received environmental approvals in Chile, representing hundreds of megawatts of new capacity.

Each of these projects needs safe, reliable electrical infrastructure. COVIBESS gives them an option that's both locally made and internationally competitive, keeping investment dollars in Chile while supporting the country's clean energy goals.

As renewable energy becomes the backbone of Chile's power system, innovations like COVIBESS prove that safety and sustainability can advance together.
