Under GE Warranty (expires 28 November 2013)

1. SCOPE OF SUPPLY
1.1 Equipment Scope Description

1.1.1 Gas Turbine
General Electric gas turbine model LM6000PD is a two-shaft/two-spool engine consisting
of a five-stage low pressure compressor, a fourteen-stage high pressure compressor, a
two-stage high pressure turbine, and a five-stage low pressure turbine. The engine is
equipped with a stainless steel mesh screen in the inlet air stream for "last chance"
protection against foreign object damage. The engine is shock mounted and shipped
in position, with the exception of the coupling spacer, which is removed and shipped
in a separate container.

1.1.2 Generator
Air-cooled open air, Brush made 2-pole generator rated at min 63,500 KVA @ 0.8 pf, 15flC
cooling air, 11,000 volts, 50 Hz, capable of handling the full continuous power of the gas
turbine at any ambient temperature throughout the operating range. A cooling water loop
and its associated fans and pumps are not required. The generator includes a brushless
excitation system with permanent magnet generator. Neutral and line side cubicles are
included. Neutral and line side cubicles are bolted onto the outside of the generator
enclosure for the Customer’s power connections.
GE Energy furnishes, located in the neutral cubicle, nine (9) current transformers and
three (3) additional current transformers for Buyer’s differential protection (4000:1), as
follows:

Qty Service European Class
3 Relaying & Differentials 5P20
3 Metering 5P20
3 Cross Current Compensation (AVR) 5P10
3 Differential Protection by Customer * 5P20
Note * 30 VA, 5P20, Rct<30 Ohm
GE Energy also furnishes three lighting arrestors and three surge capacitors mounted
in the line side cubicle.
Three (3) voltage transformers with secondary 110/Á3 V and primary 11000/Á3 V are
included in the GE Energy scope of supply.

1.1.3 Main Load Gearbox
The equipment package is supplied with a single-stage, vertical offset, parallel shaft
speed reducer with a gear rated HP of 70,000 (52,200 kW) from a gas turbine speed of
3627 RPM to a generator speed of 3000 RPM, with a 1.209:1 ratio. This unit is
manufactured and tested in accordance with API 613 3rd Edition April 1988. The actual
AGMA Service Factor is 1.35. The API service factor is 1.1. The unit design includes a
fabricated steel housing, clockwise rotation with pinion on top, double helical
precision carburized ground gear elements, split steel backed babbitt lined journal
bearings on all shafts and a low speed quill shaft.

1.1.4 Unit Enclosure
The equipment package is supplied with weatherproof acoustic enclosures. The
enclosures are completely assembled and mounted over the equipment prior to testing
and shipment. The gas turbine compartment is fully ventilated with duplex belt driven
fans. The generator compartment is fully ventilated with direct driven fans. Explosionproof
A.C. lighting is provided in both compartments. The enclosure provides
guaranteed average noise emission of 85 dB(A) at 1m distance measured at 1.5m
above grade in a free field condition, during full load operation. Noise emission could
be greater than 85 dB(A) at 1m distance measured at 1.5m above grade in a free field
condition, during equipment start-up and shut down.

1.1.5 Baseplate
The equipment package is supplied with the support structures for the gas turbine
generator set consisting of a two piece skid assembly, which is sectioned between the
gas turbine and the generator/main load gearbox. The full depth, bolted section is
designed to provide the full structural properties of the wide flange I-beams. Full depth
cross members are utilized to provide for a rigid design that is suitable for installation
in earthquake areas (U.S. Seismic Zone 4) as well as providing a convenient structure
for transportation. The base-plate support system is enhanced by the installation of a
heavy duty, welded superstructure which utilize structural tubing for wall columns and
roof beams.

1.1.6 Air Inlet System
The equipment package is supplied with a modular, three-stage filtration system
consisting of inlet screens, an EU4prefilter and an EU7 final barrier filter.
The filtration system removes more than 99.9 percent of all particles 5.0 micron and
larger by utilizing a three-stage design, that is designed to meet the following
downstream conditions:
~95% of the time, must not contain solid particles exceeding 0.004 grains/1000 cubic
feet, and
~5% of the time, must not contain solid particles exceeding 0.04 grains/1000 cubic feet.
It will be possible to replace the pre-filter and high efficiency filter without stopping the
GTG, however, replacement of the high efficiency filter with the GTG on line is very
dangerous and not recommended by GE Energy.
Acoustical louvers for noise control are installed to the intake of the inlet filter, in lieu
of the weather hoods. The acoustic louvers provided are 600 mm deep. The acoustical
louvers provides guaranteed average noise emission of 82 dB(A) at 1m distance from
the inlet filter intake, during full load operation. The estimated pressure loss added by
the louvers is 20 mmH2O. A detailed description of the acoustical louvers provided for
noise control and installed to the intake of the inlet filter is included in Section 7 of this
proposal.
All air for ventilation systems is filtered to the same level as turbine combustion air.
Filtered air is silenced before entering the turbine plenum. This design results in a
compact arrangement and eliminates the need for customer supplied inlet ducting
when the standard design is utilized. Internal lighting of the filter house is provided to
facilitate inspection and service.
Package is also supplied with platforms and ladders to service the inlet filter (internal
platforms and ladders only). These items are packaged separately for shipment.

1.1.7 Inlet Air Multi Purpose Coils
The equipment package is supplied with high performance multi purpose coils for
combustion air heating and chilling as an integral part of the air inlet system.
Customer shall provide adequate quantities of hot water and chilled water and
interconnecting piping to GE Energy furnished chilling coils at filter house.
For the Anti-Ice System, that is required to allow safe operation of the equipment
package during icing conditions, Customer shall furnish water at 27flC and 345 kPag,
for circulation through the GE Energy supplied coils. The quantity of heat should be
enough to heat the inlet air 5.6 deg C above ambient temperature when ambient
temperatures are less than -1.1 deg C and to heat the inlet air to 4.4 deg C when
ambient temperatures are between -1.1 and 4.4 deg C. No heating is required for
ambient temperatures above 4.4 deg C.

For temperatures below -9.4 deg C there is no need for anti-icing operation, due to the
very low moisture content of the air. The only expectation would be where there is fog,
snow, or other visible precipitation.
Anti-ice protection is not required during start-up and warm up period (maximum 5
MW) for up to 1 hour maximum time period.

1.1.8 Turbine Exhaust
The equipment package is supplied with a circular, axial exhaust outlet with
connection flange to facilitate in-line mounting of a WHRU.

1.1.9 Fuel System
The equipment package is supplied with a Dry Low Emission (DLE) natural gas fuel
system using an electronically controlled fuel metering valve. All necessary shutoff
valves, piping and instruments between the fuel module connection and the engine are
included.

1.1.10 SPRINT® (Spray Inter-cooling) Power Boost System
The equipment package is supplied with the SPRINT® boosts system for engine
performance augmentation. The SPRINT® boosts engine performance system uses a
spray inter-cooling design that significantly increases the mass flow by cooling the air
during the compression process.
The system is based on an atomized water spray injected through spray nozzles
placed at two locations, one between the high pressure and low pressure
compressors, and the second at inlet bell-mouth.
Water is atomized using high pressure air taken off of the eighth stage bleed. The
water flow rate is metered, using the appropriate engine control schedules and at the
inlet bell-mouth.
Bell-mouth and inter-stage portions on SPRINT® alternate operation based on turbine
inlet temperature.
If the SPRINT® boosts system is used, Customer must provide a supply of purified
water per GE specification MID-TD-0000-3 (see Section 12) to a flange connection at the
Sprint skid, at 200-450 kPag.
