The typical full load fuel flow for a 9E configuration burning natural gas is 1,350
GJ per hour, equivalent to approximately 120 mmscf per day. As a result of
potential power outages from the National Grid used for startup, Azura Power
plans to install three 3.7 MVA diesel units (approximately 40 m 3 , with piping to
the black start units) to provide the estimated 7.4 MVA required to “Black Start”
the power station.
Transmissions Line
The OCGT power station will have four transformers to step up the voltage from
15 kV to the transmission voltage of 330 kV from where it will then be fed over a
short length of overhead cable to an air-insulated switchyard before being
exported via overhead cables on a single tower to the new substation at Benin
North, located adjacent and to the south to the Project site. A Risk Assessment
for the transmission line and gas pipeline spur components will be conducted
and key recommendations will be incorporated into the EMP.
Gas Pipeline Spur
The Project site is located less than 1 km from the ELPS, the country’s main
natural gas trunkline. Natural gas will be delivered to the plant via the ELPS
and a circa 1 km spur line from the ELPS to a gas receiving station on the plant
site. This spur will share the same right of way used by the spur that connects
the ELPs to the adjacent NIPP power plant.
