El Carrizal hydroelectric power system, Bolivia

Ende (National Electricity Company of Bolivia) engaged Asociación AH Carrizal, with TYPSA as the lead partner, to develop the Carrizal Hydroelectric Project. The Project’s main aim is to generate electricity using the hydroelectric potential of Andean rivers. The field works were constrained by the considerable dimensions of the works designed in this macro project and the exceptional Andean terrain. The main components of the solution finally selected include a dam, a hydraulic diversion tunnel, a penstock, power plant and transmission line. Access roads and construction camps have also been designed. The roller-compacted concrete (RCC) dam rises 160 m high above the foundation and has a crest length of 380 m and a 1,334 hm3 regulating reservoir. The overfall spillway is 86 m long with a discharge capacity of 7,290 m³/s (1.000 year return period). The bottom outlet comprises seven 3 x 3.5 m rectangular ducts located at different heights, with...

Supervision of the desalination plant in Al Khafji

TYPSA has been awarded the contract to review the detailed design and supervise the construction works of the desalination plant in Al Khafji, in Saudi Arabia, including the photovoltaic plant to power it. The facility, developed by Advanced Water Technology, is the first desalination plant in the world to be powered by solar energy and is a milestone in the quest for sustainable solutions in the field of water management. Located on the shores of the Arabian Gulf, it is just a few kilometres from the border with Kuwait and is designed to produce 60,000 m3/day of desalinated seawater using a reverse osmosis process, to supply the town of Al-Khafji. A 20 MW photovoltaic plant will be built about 2 km from the desalination plant on a 90 ha site, making this the world’s first large-scale desalination plant powered autonomously by solar energy. The plant design, construction and commissioning works...
