The proposed amendments in Schedule I are due to the change of the
manufacturer and equipment from Goldwind to Mingyang. Literature on the
proposed Mingyang turbines to be used are attached as Annex D. The key
reasons for the changes being that these WTG's are widely used in the coastal
regions of China due to their high resistance to the corrosive salt wind air,
similar to the conditions found in the marshy land at Bhambore, Sindh. The low
voltage ride through LRVT is also particularly suited to the weak HESCO
network in the Gharo area and from the raw data from the site much higher
extreme wind conditions can be expected during the term of the Project and
the proposed new WTG MY1.5 MW-82 are the best Chinese WTG's capable of
standing up to extreme winds of up to 59.5 m/sec. A detailed study conducted
by Power China Xeibi Engineering Corporation in November, 2014 sets out a
detailed evaluation of these WTG's and can be found attached as Annex E.

Although the wind power industry develops at a fast pace, low average wind speed and high maximum wind
speed in many regions around world makes it difficult to choose a suitable type for alt those different conditions
Besides, low utilization hour of most wind turbines causes high electricity cost from wind power generation
The MY1.5MW series wind turbines are specialty optimized to answer these challenges Large diameter rotor
increases the wind swept areas. which in turn improves power output even under low wind speed Reenforcement of certain components enables the MY1 5MW Series wind turbines to have higher equivalent
utilization hours, and it can survive and perform well even under complex climate conditions The MY1 5MW
Series wind turbine alms at market for turbines suitabte for lower average Wind speed and high maximum wind
speed We are striving to provide high quality, high efficiency, and high return wind turbines for domestic and
international wind power operators

-4e
environment and possible extreme wind conditions, a re-tendering for a suitable
WTG became necessary.
Further, in order to confirm that the new WTG meets the special environmental
condition of HDPPL site and to make sure that the new selected turbine can
provide a stable and safe performance for the term of the Project, HDPPL delegated
POWERCHINA Xibei Engineering Corporation Limited (hereafter "XIBEI") to
conduct an analysis of the WTGs available in the Chinese market.
After a three month in-depth research of the Chinese wind turbine manufacturers,
"XIBEI" experts and engineers decided that the WTG of Guangdong Mingyang
Wind Power Group Co. Ltd. is best suited to meet the HDPPL site and NTDC
network requirements. The XIBEI report submitted to HDPPL is being enclosed
for ready reference.
3. Objective
As required by HDPPL, XIBEI conducted an independent evaluation of
Guangdong Mingyang WTG Model MY1.5MW-82, to check its suitability based
on practical performance of several costal wind farms in China (including the wind
farms in Dongfang Gancheng, Hai'nan), operation at high temperatures and in high
salt mist conditions. Emphasis was also given to network compatibility and safety
requirements.
4. Main Conclusions
1) MY1.5MW-82 has the required design characteristic to withstand high
temperatures and corrosive costal area environment. The WTG has proven
performance capability in salt mist conditions similar to HDPPL site
conditions.
2)
MY1.5MW-82 meets all the NEPRA Grid Code requirements and IEC/NTDC
standards.
3)
MY1.5MW-82 has a robust design for extreme wind conditions which can be
expected in the coastal areas of Sindh during the term of the Project.
Based on above requirements, the selection of MY 1.5MW-82 for HDPPL is
appropriate.
5. Short Introduction of Ming Yang MY1.5MW Series of Wind Turbines

6.1 Turbine Features
6.1.1 Doubly-fed induction generator
MY1.5MW-82 is equipped with doubly-fed induction
generator-converter system which is widely used for megawatt-level
WTGs. The system is designed for high reliability, low noise and
enhanced grid adaptability. Converter size is 30% of the WTG rated
power.
3
POWERCHINA XTBEI ENGINEERING CORPORATION LIMITED
6.1.2 Double-bearing support structure
Double-bearing support structure is adopted. Auxiliary flexible
support is designed for the two torque arms of gearbox. Front bearing
as the floating end is designed to sustain radial load while the rear
bearing as the fixing end sustains axial load. Double bearings of main
shaft sustain and directly transfer bending moment, axial force and
radial force from rotor to rigid frame. Flexible support on torque arm
effectively reduces the impact of the whole system due to torque
variation while the gear box only bears partial weight and torque,
eliminating potential risk of step-up gear box fault and ensuring more
reliable operation of the gearbox.
6.1.3 Gear box
The gearbox is manufactured by Nanjing Gearbox Company (NGC)
which is the largest and best gearbox manufacture in China. Gearbox is
designed with two-stage planetary and one-stage parallel structure that
is connected to the main shaft (3017mm Length) with clamping
sheath. Gearbox torque arm is connected to frame with elastic
components, effectively reducing vibration and noise. Gearbox
high-speed shaft end is equipped with a braking device that is
connected to generator with a yaw-control coupler. The coupler is
equipped with torque limiter which is designed to prevent the gearbox
from being damaged when instantaneous peak torque hits the gearbox
in case of generator fault. The gear box support is designed in such a
way that it can take both axial and radial shifts and dissipate it without
causing internal damage.
4
.4(
6.1.4 Yaw system
Four yaw motors accurately drive the yaw gear through a control
system. The yaw encoder keeps the yawing accurately thus
maximizing the use of wind energy and improving the efficiency of the
generator to ensure high energy output.
6.1.5 Control system
All of WTG functions are operated by control system that is provided
with operating system. Communication between nacelle control
cabinet and tower base control cabinet is performed via optic fibers.
WTG operation state, external environment and power grid etc. are
monitored by SCADA system that automatically processes WTG
operation data. Operation alarm signals are sent by the annunciater to
ensure safety of the WTG and its components. This minimizes the
WTG downtime and maximizes the machine availability.
6.1.6 Brake system
MY1.5MW-82 braking is performed by main and auxiliary brakes.
Main brake is operated on the principles of aerodynamics. Braking is
achieved through feathering. The auxiliary brake is a mechanical brake
which is installed on high-speed shaft of the Gearbox and is operated
by hydraulic system. The two-stage brakes ensure quick response, and
a safe, soft and reliable action.
6.1.7 Bearing system
MY1.5MW-82 is designed with elastic support connections at five
positions (i.e. wheel hub and electric control pitch system, gearbox and
stand, generator and frame, nacelle cover and frame, gearbox high
speed output shaft and generator input shaft). These configurations
maximally reduce WTG vibration and noise. The bearing selection is
optimized to take care of the axial & radial play.
6.2 Grid adaptability features
6.2.1 LVRT Function
Wind turbine should stay connected to the network and keep operating
following voltage dips caused by imbalances on any or all phases,
while the voltage measured at the HV terminals of grid connected
transformer should remain within the predefined limits.
5
POWERCHINA XIBET ENGINEERING CORPORATION LIMITED
Ming Yang Wind Turbine Evaluation Report - November 2014
MY1.5MW-82 is equipped with an excellent LVRT functionality. If the
voltage at the point of common coupling with the Grid remains above
the contour line shown below (figure 1), the wind turbine keeps
operating. If the voltage at the point of common coupling falls below
the contour line shown below (figure 1), the wind turbine is allowed to
trip.
a) The Wind turbine is able to ride through a voltage dip of 0.2 pu at
the generator terminals for 625msec. The Grid Code in Pakistan
asks for LVRT at 0.3 pu at the generator terminals for 180msec
only. The LVRT performance of MY1.5MW-82 WTG is very
much required for HESCO network at Gharo.
b) The voltage of the grid connecting point recovers to 90% of the
rating voltage in 2s after a drop and the wind turbine is able to
keep operating.

6.2.2
Grid adaptability
When the voltage at the point of common coupling with the grid has a
deviation between -10% to +10%, wind turbines will keep operating
normally. When the deviation is above +10%, the wind turbines will
keep operating for at least 30min. When the voltage at the point of
common coupling is 90% of the rated voltage, the wind turbines will
meet the LVRT requirements.
6.2.3 The power quality
The power quality of MY1.5MW-82 meets the requirement of
IEC61400-21 standard. (The reports are shown in the annex No8.5.)

POWERCHTNA XIBEI ENGINEERING CORPORATION LIMITED
6.3 Design Features for Corrosion Protection
(specially salt mist prevention)
(1)
HDPPL WPP is located in a coastal area. The geographical conditions
lead to a high air humidity and salt concentration in the area. To
overcome corrosion, all the components used in MY l .5MW-82 are
coated with corrosion resistance paint.
(2)
Various anti-corrosion technologies are used for various parts
including blades and towers during the WTG manufacturing. Hot dip
galvanizing, thermal spray, zinc composite anticorrosion coating and
Dacromet treatment are accordingly adopted.
(3)
The electrical equipment is specially designed to resist salt mist
corrosion. Stainless steel cabinet in 1P54 design is used to house the
pitch system. The cabinet is provided with a radiator fan and heating
element as well as temperature and humidity transducers. The heater
and radiator fan can be regulated by setting relevant parameters to
eliminate interior humidity and prevent salt mist corrosion.
(4)
The generator enclosure is in IP54 design, while, air/air cooling mode
is applied for the generator during which the internal cycle is
completely isolated from the environment and the heat in the generator
is dissipated through external cycle. The cooling mode can effectively
protect the generator rotor and interior components from salt mist
corrosion. All internal control circuit boards of the transducer are
applied with coating which is of good salt mist corrosion resistance.
The minimum IP grade of the control cabinet is IP54. The control
cabinet is provided with heater element and radiator fan as well as
temperature and humidity transducers.
(5)
As for components and parts requiring short-term corrosion protection
during storage and transportation process, the surface of components
and parts is applied with preservative oil (wax) or lubricant grease. In
addition, the surface without anti-corrosive treatment shall be wrapped
up with antirust membrane (preservative film or anti-tarnish paper to
enhance the corrosion resistance of components and parts during
storage and transportation process. Measures mentioned above can be
used as short-term protection for components and parts surface without
corrosion protection painting during storage and transportation process
of the WTGS.
Ming Yang has special knowledge in corrosion prevention gained from
its extensive offshore experience.

Operation temperature range
-10 °C to + 45 °C
Storage temperature range
-20°C to + 50°C
average humidity density
85%
Max. humidity
95% (condensation)
6.4.2 Drive train
The temperature control of main shaft bearings is achieved by grease
lubrication. The seal system of the main shaft bearings of
MY1.5MW-82 is optimized to fulfill high temperature operation
requirement. Suitable grease is also chosen for lubrication.
6.4.3 Gear box

rotor shaft bearings.
6.4.5 Nacelle control cabinet and tower base control cabinet
A/C is used in both nacelle and tower base control cabinets to reduce
the temperature.
6.4.6
Inverter
The max. ambient temperature of the inverter (located at the tower base)
for the HDPPL project is 45 Deg C.
6.4.7 Control scheme of safety and protection operation
Control scheme of safety and protection operation of MY1.5MW-82 is
designed to fulfill the HDPPL site requirements.
6.5 Rigid tower design
Rigid tower design has been adopted for MY1.5MW WTG. This design has
high intrinsic frequency which avoids the rotating frequency and the flap wise
frequency of the blade. The rigid tower can avoid the tower resonance without
changing the rotating speed, therefore, it extends the operation speed range of
the generator and keep optimized tip speed ratio and maximum Cp within the
whole operation range of the generator. The power generation efficiency and
production of the WTG /wind farm can thus be maximized.
Ming Yang tubular tower has complete safety protections for human beings.
The tower is designed to suit all adverse site operating conditions.
6.6 Independent intellectual property right of control system
Ming Yang owns the IP rights of the entire control system including the source
code. This advantage allows the engineers to adjust and optimize the wind
turbine parameters according to the wind regime and weather conditions,
improving the overall wind power efficiency by maximizing the power
generation efficiency of the wind farm.

A Statement Of The Impact On The Tariff, Quality Of Service And The
Performance By The Licensee Of Its Obligations Under The License Under
Regulation 10 (2) (c) Of The NEPRA Licensing (Application & Modification
Procedure) Regulations, 1999.
Respectfully sheweth,
The Project is an upfront wind tariff project and therefore assumes the wind
risk of any decline in output. No adverse impact on the tariff is foreseen by the
change in equipment rather the assumption of wind risk by the power producer
will facilitate a move towards market based mechanisms & away from public
subsidies given in the cost plus tariff. Payment being only for electricity
produced is the proper way forward for the electricity sector in Pakistan. Both
the quality and the performance of the licensee is expected to improve with the
proposed induction of the new wind turbines from Mingyang MY1.5 MW-82
which are widely used in the coastal regions of China due to their high
resistance to the corrosive salt wind air, as found in the marshy land at
Bhambore, Sindh. The low voltage ride through LRVT is also particularly suited
to the weak HESCO network in the Gharo area and from the raw data from the
site much higher extreme wind conditions can be expected during the term of
the Project and the proposed new WTG MY1.5 MW-82 are the best Chinese
WTG's capable of standing up to extreme winds of up to 59.5 m/sec. A detailed
study conducted by Power China Xeibi Engineering Corporation in November,
2014 sets out a detailed evaluation of these WTG's and can be found
attached as Annex E to s10 (2) (b) reasons in support.
This change of equipment is also reasonably necessary to ensure the
continuous, safe and reliable supply of electric power during the license period
to the consumers keeping in view the financial and technical viability of the
licensee. The tariff will not be changed, the quality will be improved and there
will not be any adverse effect the performance by the licensee of its obligations
under the License and is likely to be beneficial to the consumers.
