In general terms, the plant is operated from the control room which sends out the requisite number of monitoring and
control signals to execute the actions involved in running the plant.
The gas turbine, steam turbine and other packaged plant facilities located at the site such as the water treatment
plant, the chemical dosing unit, seawater filtering unit, etc, all have their own control panels so that they can be
operated locally. These local panels are linked to the plant´s distributed control system when sends out commands
controlling the main functions they perform.
The plant´s buildings and facilities are located in a relatively compact area.
Industrial architectural criteria normally applied to this type of plant have been used to design the buildings.
The various zones that make up the plant are described below:
The gas turbines and their auxiliary systems are housed in a two-storey building. The turbine´s air intake
filters are supported on the lowest section of ceiling in the building. Two overhead travelling cranes have
been installed for maintenance purposes, one in the turbine zone and the other in the turbine generator zone.
The steam turbine stands on a platform with the condenser situated beneath the low-pressure stage exhaust. The turbine´s
auxiliary facilities (oil, lubrication, electrical support unit, hydrogen sealing oil, etc.) can be found on the mezzanine
The overhead travelling crane runs parallel to the turbine shaft and can access all areas.
The water supply pumps are located at ground level between the turbine building and the electrical control room. The
degasifier is situated above them on the same level as the turbine.
Heat recovery steam generator zone
The main transformers can be found between the turbine building and the substation, facilitating output towards the latter.
Electrical control room, main control room and offices
The heat recovery steam generators are housed inside a covered facility. These boilers are connected to a 125-m smokestack
with a concrete shaft and independent gas pipes for each boiler.
The electrical equipment rooms and the chemical laboratory are on the ground floor. The main control room is on the top
floor, right above the electrical equipment rooms. Alongside are the general offices, which sit above the laboratory.
A pipe rack runs between the gas turbine and boiler buildings and carries the main and auxiliary pipes.
The water treatment units, sewage tanks, and the compressed-air and fire-prevention systems are located right
by the entrance to the facility.
