SPANCOLD

In 1933, Spain joined the International Commission of Large Dams (ICOLD). Since then, the Spanish National Committee of Great Dams (SPANCOLD) has been working within ICOLD with such intensity that twice have occupied Spanish presidents the Presidency of the Organization: José Torán (1970-1973) and Luis Berga (2006- 2009).

Water Storage and Hydropower Development for Spain

Water resources

The average annual precipitation is 670 mm. The total meanannual precipitation volume is 331 km, of which 114 km is run off. The regulated resources have a volume of 60.9 km.

Spain has 987 large dams in operation, which include 246 embankments, 691 concrete dams and 20 composite dams. The total regulated storage volume of all dams is 61.5 km3.

The Ministry of the Environment is in charge of water resources; part of its organization are basin authorities for each major river basin.

Power sector

Spain has four main power producers. Endesa, which is a majority-owned subsidiary of Italy's Enel, is the country's largest in terms of annual production and number of customers and second largest in terms of installed capacity.

Iberdrola is the largest in terms of installed capacity and second largest in terms of annual output and customer base.

Gas Natural Fenosa has a total installed capacity of12 716 MW, including 2064 MW of hydro.

The fourth largest power producer and distributor is EDP. Red Electrica de Espana is the national transmission system operator.

Hydropower development

The gross theoretical hydropower potential in Spain is 162 000 GWh/year, the technically feasible potential is 61 000 GWh/year and the economically feasible potential is 37 000 GWh/year.

So far, about 52 percent of the technically feasible potential has been developed.

Symposium Program

Spanish National Committee on Large Dams (SPANCOLD), Japan Commission on Large Dams (JCOLD), French Committee on Large Dams (CFBR) and Chinese National Committee on Large Dams (CHINCOLD) have the honor to invite professionals to the 9th International Symposium on Roller Compacted Concrete (RCC) Dams and Cemented Material Dams, which will be held in Dec.4th-8th,2023 in Guangzhou City, China.

RCC dams have the virtues of saving a great deal of concrete, building quickly, making project cost down and early bringing into playing project advantages and so on. Hence, the technique of constructing dams has been quickly spread and applied since it came out. Today there are more than 400 RCC dams in more than 40 countries. Great successful experiences and advanced technologies have been achieved. CHINCOLD and SPANCOLD have devoted to promote the technology from early 1990’s. The first Symposium on RCC dams was jointly organized by the two committees in 1991 in Beijing China, which was a success start of the series of RCC Symposiums.

Cemented Material Dam (CMD) is a new type of dams, which includes Hardfill dam, Cemented Sand and Gravel dam (CSG), Cemented Sand, Gravel and Rock dam (CSGR), Rock-filled Concrete dam (RCD), Cemented Soil dam (CSD), and so on. There are more than 200 CMD projects constructed and under construction.

The 9th International Symposium on Roller Compacted Concrete (RCC) Dams and Cemented Material Dams will provide a platform for practitioners, engineers, researchers, scientists, managers and decision makers from all over the world to exchange ideas and technology about the latest developments dealing with RCC dams and CMDs. Beside international best practice, the participants will also have the occasion to visit some famous RCC dams and CMDs in China in operation or under construction.
