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

the area reserved for the HRSG and steam turbines which can later form part
of the CCGT power station (Figure 3.1).
Construction is expected to start in the fourth quarter of 2012 as indicated in
Table 3.4. Construction activities will generally be restricted to daylight hours,
however the final stages of installation and commissioning may proceed 24
hours a day, seven days a week.
Screw piling (auger piling) of the foundations for the gas turbines and other
large items of equipment will commence six months into the construction
schedule, and will last for three to four months. Once the piles are in place,
concrete slabs will be constructed and turbine pedestals constructed which
will involve some large pours of concrete. At this stage the gas turbine
building will be constructed which will be the first visible impact of the power
plant. The construction of the overhead 330 kV cables, which will evacuate
power from the power plant and onto the national grid, will commence soon
after financial close and will connect the power plant to the national grid at
around 15 months.
The gas turbines and other heavy equipment will be delivered in the period
from 12 to 18 months which will involve some abnormal loads being moved
on the roads during this period.
After around 18 months general site activity will decrease as the project moves
into commissioning where there will be a relatively small group of highly
skilled engineers and technicians commissioning the power plant.
3.5.3 Sourcing of Equipment and Material
Equipment supply within the EPC Agreement will be for the EPC contractor
to determine, with Azura Power retaining rights of approval. The
manufacturer of the gas turbines and the manufacturer of the large items of
machinery will be agreed at the time of the tender for the EPC contract. Azura
will reserve the right to review all suppliers of major equipment and materials
specified in the Bidder’s proposal or subsequently identified during the
design phase, and to reject any suppliers whose equipment quality,
performance or repair service has been unsatisfactory on other projects. The
supply of smaller items of equipment and machinery will be mostly at the
discretion of the EPC contractor with either some right of approval by Azura
Power or some period of extended warranty made available to Azura Power
by the EPC contractor.
Raw materials will be sourced locally to the extent possible. Heavy
equipment that is sourced externally will be transported using the main
transportation route identified. The bridges on the route between Koko Port
and the Project site have a proven capacity to withstand the weight of the
heavy equipment required (up to 200 tonnes).
