At the moment, Coneléctricas R.L is making the studies for the construction of the Hydroelectric Project Pocosol, located in Peñas Blancas of San Ramon.
The hydroelectric development with waters of Peñas Blancas' river is tried, in its left margin, for a production of 26,000 kilowatts. They have already acquired the 100% of necessary lands for the project.
