The Casecnan Multipurpose Power Project:

A Milestone Achievement


  • It is an Awesome feat of modern engineering and the singular culmination of its builders' dogged determination.

  • The massive $640 million Casecnan Multipurpose Power Project in Pantabangan, Nueva Ecija - whose impact is anticipated to redound just as massively to agriculture based Philippine economy - is colossal in every way.

    And the ground-breaking project will be officially inaugurated on Sept. 28 ,2001.

    The Casecnan Multipurpose Power Project aims to provide adequate irrigation for the Central Luzon, the Philippines main rice producers (or "Rice Bowl" as it is referred to) and to provide extra power for Luzon's electrical supply by harnessing the waters of the Casecnan River in Nueva Viscaya.

    It is anticipated that when all the irrigation channels will have been completed, the project may well convert the Philippines to being a rice exporter.

    The project has three major components:

    • Two diversion weirs (dam placed across the rivers to divert water): Nueva Viscaya's Casecnan weir and the Taan River Weir;

    • An underground tunnel that is 6.3 meters in diameter and which traverse for 28 kilometers into the Pantabangan reservoir in NUeva Ecija; and

    • An underground powerhouse.

    From the Nueva Viscaya mountain area, the two dams that have been constructed on the Taan and the Casecnan rivers form two reservoirs. From  the dams, water passes in through the tunnel and is taken in by two intakes. From the intake area, water will pass down to the powerhouse. The turbines will generate 150 megawatts of power which will go into the Luzon grid. After water has passed through the turbines, it exits into Pantabangan Lake where it will replenish the water there. From this Lake, the water passes into channels to irrigate the rice fields.

    "The Cagayan River originates in Nueva Viscaya and goes out into the Pacific Ocean," explained Armando de Rossi, the indefatigable Regional Director for Asia of C.M.C. Ravenna, the project consortium's leading company. "The Idea was for the two dams to divert the water through the tunnel and bring it to this site where it can be utilized for irrigation and power. brought to the Pantabangan dam(an old plant not generating enough power) the water will generate more power and irrigate 65,000 hectares of the country's 'Rice Bowl'."


"The primary purpose of the project ," elaborated by California energy's Steve Lyons, "is to bring 80 cubic meter/sec of water down to the reservoir which will allow it to provide irrigation for another three to four months a year and extra electricity from the powerhouse."

In 1997, California Energy International, under a build, operate and transfer scheme, awarded the EPC (engineering, procurement and construction) contract for the Casecnan Multipurpose Power Project in 1997 to CP Casecnan, a consortium of two world famous Italian construction companies: CMC Asia and Pizzarotti SpA and several other world-famous engineering companies.

"It was important that we had a world-class consortium working for us," emphasized Steve Lyons. "This is a very sophisticated project. It is one of the largest of its type in the world."

C.M.C. di Ravenna, Europe's largest cooperative, led the consortium. C.M.C. di Ravenna has been consistently ranked as one of the top five major Italian construction Companies in the last 10 years. established in 1901 by a small group of workers in Italy's Romagna region, it has since explained worldwide with offices in 11 countries and in four continents. C.M.C. di Ravenna specializes in complex projects. iwc replica
