The energy produced by the Chaglla Hydroelectric Plant is delivered to the National Interconnected Electric System (SEIN) through the LT Chaglla – Paragsha (220 kV) and LT PCH – Piedra Blanca (34.5 / 138 kV) Transmission Lines through the LT line Tingo María – Huánuco for the consumption of the Huánuco Region and the country.
Its main transmission system is made up of lines L-2150 and L-2151 at 220 kV and rises from the Chaglla Substation at 900 masl, in the department of Huánuco, and runs 127.5 km to the Paragsha Substation at 4400 masl, in Pasco; where it connects to the Peruvian electrical system (SEIN).
The energy produced by the Small Hydroelectric Plant (PCH) delivers energy to the Huánuco Region through the L-1054 line of 25 km at 34.5 kV, which is connected to the Piedra Blanca substation (34.5 / 138 kV). This, in turn, is interconnected with the Piedra Blanca – Tingo María and Piedra Blanca – Amarilis substations thanks to lines L-1121 and L-1142; respectively.
