Design and Execution of the Està Tunnel Repair Work in (Panama)
On 7 June, 2012 Panama’s Està hydroelectric power station resumed operations after nearly 2 years out of service due to the
problems detected in the load tunnel of the facility. Following the repair work carried out by the company Obras Subterráneas on
the above-mentioned tunnel, owners AES Panamá now benefit from a greater generation capacity, as the load loss in the tunnel
has decreased by 30%.
