IBERDROLA Ingeniería has completed construction of a 420MW combined cycle plant in Riga, Latvia, able to supply a fifth of the country’s electricity needs and reduce its energy dependence by 30%.

This is the first plant of this type developed by the IBERDROLA Group subsidiary for third parties abroad and marks a major milestone in the Company’s international expansion strategy.

After the plant passed the test period successfully, IBERDROLA Ingeniería delivered it to local utility Latvenergo at an event held yesterday in the country’s capital attended by representatives of the two companies.

Specifically, Jesús Rodríguez de Diego Zamorano, site manager, represented the IBERDROLA Group, while Erick Priedneiks, project director on behalf of the client, represented Latvenergo.

Two years ago, the IBERDROLA Group won the contract not only to build the plant, but also to oversee its operation and maintenance. Worth around €300 million, this was the largest contract won by any Spanish company in Eastern Europe at the time.

Once the Riga combined cycle plant comes on stream, IBERDROLA Generación with oversee its operation and maintenance for a period of 12 years. This is the first contract of this type won by this business area.

To perform these tasks, which will be carried out by professionals at the IOMSA (IBERDROLA Operación y Mantenimiento, S.A.) subsidiary, the plant will be connected to the CMDS (monitoring, diagnosis and simulation centre), which was set up in June 2002 to control the operation of all the Company’s combined cycle facilities.

Electricity, heating and hot water

Among the world’s leading energy engineering companies, IBERDOLA Ingeniería y Construcción oversaw the turnkey construction project. To utilise part of the infrastructure, this modern combined cycle facility was built on the site of an existing thermal plant (TEC-2), which was put into service between 1973 and 1979.

The electricity efficiency of the plant is over 57% and its total efficiency (electricity + heat) is over 85%. By using residual heat, the plant will provide heating and hot water to the southern part of the city of Riga, with a population of over 700,000.

The new plant’s configuration is 1+1 (1 gas + 1 steam turbine). IBERDROLA Ingeniería will provide solutions already tested in the construction of other combined cycle plants for the Group in Spain, Mexico and Brazil.

Leader in developing combined cycle facilities in Spain, IBERDROLA ended the third quarter of 2008 with nearly 13,000 MW of combined cycle capacity throughout the world: 5,875MW in Spain, 1,900MW in the UK, 5,150 in Latin America and 25MW in the US.

Promoting combined cycles underscores IBERDROLA’s firm commitment to clean and efficient generation technologies, to the environment and to the Kyoto protocol, and shows that sustainable development is part of the Company’s core strategic values.
