The Tapada do Outeiro Power Plant is located in Medas, Gondomar, in the banks of the river Douro, some 18 km east of Oporto city in northern Portugal.
ADDRESS: Central de Ciclo Combinado da Tapada do Outeiro - Broalhos, 4515-430 Medas - PORTUGAL
COORDINATES: 41.070268; -8.460593
COMMERCIAL OPERATION: 1999
INSTALLED CAPACITY: 990 MW
NUMBER OF UNITS: 3 (330 MW/unit)
FUEL: Natural gas
The Tapada do Outeiro power plant is a 990 MW Combined Cycle Gas Turbine (CCGT) power plant, with three 330 MW combined cycle modules or "generating units", each consisting of a gas turbine and a steam turbine in line, both driving the same generator placed between them. Between the generator and the steam turbine there is a synchronous clutch.
The power plant achieved full commercial operation in August 1999.
Compared to a traditional fossil-fired power plant, this combined cycle plant demonstrates superior levels, both in terms of efficiency and improved technology that lies in the combining mode of the gas and the steam turbines. The heat contained in the exhaust gases of the gas turbine is harnessed to create steam in the heat recovery steam generator. This steam then drives the steam turbine to generate additional energy without the need for added fuel. The plant converts more than half of the chemical energy contained within the fuel into electrical energy.
In order to improve its environmental performance, low NOx burners were recently installed to reduce these greenhouse gas emissions.
Portugen, is responsible for the day to day operation and maintenance of Tapada do Outeiro.
