Hatch engineers 40 MW San Andrés power plant
January 3, 2011
Hatch has received a direct assignment from ICAFAL Ingeniería y Construcción S.A. for the development of the basic and detailed engineering for the 40-MW San Andrés power plant near Santiago, Chile.
The scope consists of updating the project’s basic engineering from 30 MW to 40 MW, and the development of the detailed engineering for HydroChile’s San Andrés Hydroelectric Project.
The San Andrés power plant is located on the San Andrés River between elevations 2,410 and 1,935 metres above sea level in Region VI of Chile, approximately 150 km south of Santiago. The power plant is designed for a gross head of 480 m, a design flow of 10.3 m3/s, and an installed capacity of 40 MW. The development considers an ecological flow of 0.37 m3/s.
Hatch will design the following:
- Intake (barrier and intake)
- Regulating pond
- Steel pipe
- FRP headrace
- Open-cut powerhouse
The deliverables will include all construction drawings (hydraulic, civil, structures and mechanical) as well as supporting calculation sheets and the actual take-offs.
The assignment began in September. The schedule includes three months to update the basic engineering and eight months for the development of detailed engineering.
ICAFAL has the EPC contract for the hydroelectric project. This is the first detailed engineering to be performed by Hatch Santiago’s Energy business unit under an EPC contract.
