In 2013 the Government of Malta has adopted a new energy policy. It was decided to drive investment in new electricity generation with state of the art technology and to reduce the use of fuel oil by conversion of a 150 MW diesel power plant. At the same time, electricity prices for consumers were to decrease by 25% and emissions to be reduced to meet EU standards. Thus, the Maltese utility Enemalta has tendered a project involving LNG storage, regasification and a power plant. The project was awarded to ElectroGas Malta with GEM Holdings (a group of Maltese companies), Socar Trading and Siemens Project Ventures as shareholders. ElectroGas Malta will operate, maintain and provide fuel for the complete plant throughout the duration of the Power Purchase (PPA) and Gas Supply Agreements (GSA). It will supply natural gas as re-gasified LNG which shall be imported via a new receiving and storage facility. The selected technical solution involves the Siemens CCPP SCC-800 3x1C (3xSGT-800 gas turbines, 3xheat recovery steam generators and 1xSST-900 condensing steam turbine) with an output of 205 MWel. This solution allows for high efficiency load following (flexibility) while, at the same time, providing high availability. The plant will be integrated into the storage and regasification process. In order to increase overall capacity of the plant at higher ambient temperatures, the gas turbine inlet air will be cooled using “waste cold” from the LNG re-gasification plant. Enemalta expects that this new investment will enhance Malta’s efficiency in generation to ca. 53% and reduce emissions by 50% and particulate matter by 90%. In this presentation we will explain how a solution based on an industrial CCPP using LNG will contribute to meeting the Maltese energy targets. Siemens is not only the turnkey supplier of the power plant but also an important partner on the financing side, a vital element to making the project viable.
