DTCEA-TS ensures the operation of air navigation equipment with solar panels in Tiriós (PA)

With the objective of ensuring the operational functionality of air navigation equipment at lower operational costs, logistical effort, and environmental impact, the Brazilian Air Force (FAB) invested in a sustainable energy generation project, considered a pioneering initiative in Brazil.
The use of photovoltaic panels, which convert sunlight into electrical energy, became the best solution for Tiriós, located in the state of Pará on the border with Suriname. The region is characterized by its difficult geographic location and lack of commercial electricity, with air access being the only means of entry.
In operation since 2015, the hybrid station installed at the Tiriós Airspace Control Detachment (DTCEA-TS) integrates photovoltaic panels with diesel generator sets. The unit is subordinated to the Fourth Integrated Air Defense and Air Traffic Control Center (CINDACTA IV).
The solar panels produce up to 268 kilowatts of power and are capable of autonomously supplying the DTCEA-TS for up to ten hours per day. The solar energy system consists of 1,072 photovoltaic panels and five banks of 24 ventilated stationary batteries, which power the station’s load with an estimated lifespan of 20 years. Since its operation, the project has enabled a 45% reduction in energy generation costs for the maintenance of the unit.
The Tiriós photovoltaic power plant is not connected to any commercial energy concessionaire, operating fully autonomously. Over the years of its use, compared with energy generated by diesel engines, it has been observed that the electrical energy quality is higher, with fewer operational interruptions, contributing to the high availability of air navigation systems installed in the Amazon.
The organization’s importance is also linked to the development and integration of the region. To reduce distances and save costs, remote monitoring equipment was installed, allowing real-time supervision and control so that CINDACTA IV technicians can perform preventive and corrective maintenance procedures without needing to be physically present at the Tiriós station.
When technology works in favor of sustainability, the results are always positive. The solar panels ensure the operation of air navigation equipment, contributing to the control and defense of airspace along the borders with the Guianas and Suriname.
