Azura-Edo Independent Power Plant Environmental Impact ... - IFC

3.3.4 Administration Buildings
The administration buildings will be located next to the workshop and will
comprise office space, kitchen and toilet facilities.
3.3.5 Access Roads and Unloading Areas
The proposed site location is directly accessed via a three kilometre length of
tarred road which, in turn, connects to the Benin City Bypass. This bypass
which encircles Benin City is a major expressway and is in excellent condition.
It is anticipated that there will only be a couple of dozen vehicles on or
visiting the Site during a normal working day, see Section 3.2.9. In addition
there will be turning areas for trucks and parking areas for cars.
3.3.6 Compressed Air and Ventilation Systems
The compressed air system compresses, stores and delivers medium pressure
(30 bars) compressed air to start the diesel engines. The system includes:
• dual air compressors;
• compressed air storage tanks;
• air-start system for engines; and
• instrument and service air system.
All the offices onsite and the control room and control equipment rooms will
be air conditioned. The gas and steam turbine buildings will be ventilated by
natural ventilation (louvres).
3.3.7 Lube Oil System
The purpose of the lube oil system is to deliver clean, cool, lubricating oil to
the engines at the proper pressure and temperature. This is accomplished by
a series of pumps, coolers, tanks, and filters. Lube oil is circulated to the
engine and back in a continuous loop, via a 12,500 l lube oil circulating tank
that serves as a central receiver. Each gas turbine has its own independent
lubricating oil system.
3.3.8 Control System and Communications
The power plant will include state-of-the-art communication and controls
systems comprising a freestanding common plant control PLC panel, a
measurement and protection unit and a plant desktop SCADA (Supervisory
Control and Data Acquisition) system. Security camera supervision systems
and internal communications systems will also be installed within the plant
and elsewhere within the Project site.
