RR Projects for the development of a novel modular air cooled condenser (MACC) for steam power plants. The technology is designed and manufactured at their plant in Tullamore. By modularizing the air cooled condenser design and integrating speed controllable fans the MACC has achieved an efficiency gain of 4% over conventional air cooled condensers. Each module measures 2m X 8m and consists of a bank of finned tubes and a bank of speed controllable fans. On a 250MW plant it is estimated that the efficiency gains would result in a revenue increase of almost €12M/year. Once commercialized, this technology could be used worldwide to deploy Concentrated Solar Power (CSP) plants. The technology has been installed on a 1MW CSP plant in Australia, after which RR Projects intends to progress to a 30MW Plant.
