Aggreko signs 100 MW gas project for Dominican Republic

Aggreko is pleased to announce the award of a two year project, subject to final approvals and closing conditions usual for an agreement of this type, for 100 MW of gas powered generation in the Dominican Republic.

The agreement, which is valued at circa $80 million over a two year period will serve as an interim emergency solution to Edenorte, the Northern electrical distribution company of CDEEE, in the Dominican Republic. There is an urgent need for utility power in the Dominican Republic due to a rapid increase in demand for electricity, driven by economic growth in the country, which has affected national grid stability.

Celso Marranzini, Vice President of CDEEE has said, "this agreement is part of the short term solution to the energy situation that the country has suffered for more than 40 years, and the presence of Aggreko in the Dominican Republic is a clear sign of confidence in the country's economic stability and the continued support that President Leonel Fernández has given to the electrical sector."

Rupert Soames, Chief Executive of Aggreko said, "we are delighted to be have been selected to be of service to CDEEE to help address the temporary power needs in the Dominican Republic. This will improve the stability of the national grid which has had to deal with rapidly increasing demand due to the rapid economic growth of the country".

Aggreko provides power and temperature control solutions to customers who need them either very quickly, or for a short or indeterminate length of time. Examples would be the supply of power to an industrial site which needs to service its permanent power supply, supplying a whole city in times of power shortage, or providing a major sporting event with power and cooling systems. We serve our customers either through our 165 service centres, which we call the Local Business, or globally through our International Power Projects business.

In the Local business, which accounts for about half of our revenues, we hire our equipment to customers, who then operate it for themselves, although we retain responsibility for servicing and maintaining it. In the International Power Projects business, which also accounts for about half of our revenues, we operate as a power producer. We install and operate power plants and we charge our customers both for providing the generating capacity, and for the electricity we produce. We design and manufacture equipment specifically for these requirements in our factory in Dumbarton, Scotland.

Aggreko is the exclusive supplier of temporary power to the London 2012 Olympics, and we also provide power to national grids in around 50 countries including Indonesia, Bangladesh, Angola, Kenya, Venezuela, Chile, Braziland the USA.
