ONS is Brazil’s national electricity operator, managing electricity generation and transmission across the country. To improve its energy dispatch process and grid stability while integrating growing renewable energy, ONS launched a digital transformation to automate the real-time dispatch of renewable energy sources like wind and solar. By implementing AVEVA™ PI System™ alongside its own tools, ONS optimized real-time grid management, reduced manual coordination, minimized energy waste, and enhanced operational performance.
"We can't operate without AVEVA PI System. We got a 98% reduction in operational time. An operation that used to take 40 minutes now takes less than a minute. Now, the operators can now focus on what really matters."
-- Kaio Kopko, Electrical Engineer, ONS Brazil
