Launched in 2019 in partnership with the State Government, the Paraná Trifásico Program has established itself as the largest rural power grid modernization program in Brazil. The initiative was designed to expand the availability of three-phase power in rural areas, strengthen the electrical infrastructure in rural areas, and drive the economic and social development of Paraná.

The program included the construction of new three-phase grids, the reinforcement of key junctions in the rural distribution system, and the implementation of automation technologies capable of identifying and isolating faults more quickly, thereby reducing the impact of power outages. These improvements have provided greater quality, reliability, and safety for rural producers, agribusinesses, and rural communities.

With a more robust and modern grid, producers now have better conditions to expand their operations, adopt new technologies, increase the efficiency of production processes, and meet the growing demand for energy on rural properties. In addition, the program helped reduce the need for fossil fuel-based energy solutions, promoting more sustainable and competitive production.

In 2025, Copel completed the Paraná Trifásico project, reaching the milestone of 25,000 kilometers of three-phase grids deployed across 395 municipalities in Paraná, with investments totaling R$ 3.3 billion. The initiative represented a milestone for the state’s energy infrastructure, reducing power outages, improving the quality of supply, and strengthening the productive capacity of Paraná’s agriculture and agribusiness sectors.

The new infrastructure significantly improves the quality of power supplied to rural areas, reducing voltage drops and fluctuations, enabling the use of higher-powered equipment, and facilitating access to new technologies. As a result, the program has expanded opportunities for economic development in rural areas, contributed to job and income creation, and strengthened the competitiveness of one of the most important sectors of Paraná’s economy.

In total, the state’s regions received the following network extensions under the Paraná Trifásico Program: Southwest (3,311 km), West (5,059 km), North (3,520 km), Northwest (4,378 km), South-Central (5,829 km), and East (2,965 km), highlighting the initiative’s reach and scope across all regions of Paraná.
