The collaboration between Prysmian and ISA Energia Brasil involved deploying the E3X technology, a ceramic coating applied to aerial conductors using advanced robotic cleaning and coating processes while the lines remain energized. This method improves heat dissipation in conductors, boosting transmission efficiency and capacity without physical conductor replacement. The E3X coating can increase current transport capacity by up to 25%, with the Rosana project targeting an 8% increase on the treated segment. This pilot aligns with Prysmian’s strategic positioning as a leader in cable solutions supporting energy transition and digital transformation worldwide.
These technological advancements support Brazil’s ongoing challenges in integrating renewable energy sources amid infrastructure constraints and energy curtailment issues. ISA’s digital substations, battery storage projects, and line modernization efforts underscore its commitment to grid modernization, enhanced reliability, and sustainability. These innovations reduce the need for costly new facilities and environmental impact, while facilitating a flexible grid capable of supporting increasing renewable penetration and demand growth. The success of these projects signals a growing trend in Latin America for incorporating smart grid technologies that improve operational efficiency and system resilience amidst the evolving energy landscape.
