The Chaglla Hydropower Station stands on the Huallaga River in Peru"s Huánuco region, deep in the eastern Andes. With an installed capacity of 456 megawatts, the station generates an average of about 2 billion kilowatt-hours of renewable electricity each year, feeding Peru"s national grid.

　　The project company, Empresa de Generación Huallaga (EGH), is a subsidiary of CTG.

　　Cierto joined the Chaglla project in 2012, when construction teams still had to move materials and workers through areas without roads. He initially operated boats for the construction work. As the reservoir expanded, the boats began to serve another purpose: carrying the communities whose old routes had been submerged or cut off.

　　Passengers initially felt nervous about traveling on the water. The operators taught them how to use life jackets and paid particular attention to children.

　　Over time, the boat became part of the rhythm of community life. People no longer had to plan a trip around a difficult return journey or remain away from home for several days.

　　Juan Espinoza Lázaro, 48, makes a living from agriculture and fishing. He often travels to Agua Nueva to grow beans with his friend Yonel Escalante.

　　Lázaro remembers carrying coffee sacks weighing 30, 40 or even 50 kilograms on his back. He would walk until he found a mule or donkey to help transport the load, then continue toward the nearest town.

　　"Before, it was very difficult. Remembering those days is painful," he told the Global Times, adding that the hardships of that former life remain etched in his memory.

　　He recalled walking 13 to 15 hours to reach the nearest town, while people from Agua Nueva could spend 15 to 18 hours traveling to Cayumba. The route from Chulla or Pueblo Nuevo to Chaglla once took nearly seven hours.
