Wind Turbine in Gharo, Sindh: Wind Speed, Best Months, Power Potential & Complete Guide
Wind Turbine in Gharo, Sindh: How Good Is the Wind?
Imagine you have two identical wind turbines.
You place one in an area where the wind is weak and blocked by buildings. You place the other in an open area where strong wind blows for many hours every day.
Although both turbines are exactly the same, the second one can produce much more electricity.
This is why location is one of the most important parts of a wind-energy project.
Gharo, in District Thatta, Sindh, is especially interesting because it lies in the famous Gharo–Keti Bandar wind corridor. The Sindh Energy Department describes this corridor as about 60 km wide and more than 180 km long, extending through several parts of southern Sindh. The department estimates that the wider corridor has more than 60,000 MW of exploitable wind-power potential.
But what does that mean for someone thinking about installing a 1kW, 2kW, 3kW, 5kW or 10kW wind turbine in Gharo?
To answer that, we need to understand the actual wind.
Where Is Gharo and Why Is It Important?
Gharo is located in Thatta District in Sindh.
It is part of the coastal wind region of southern Pakistan, where winds influenced by the Arabian Sea and seasonal weather patterns can become much stronger than in many inland parts of the country.
This is not only a theoretical wind area.
Large wind projects have actually been constructed around Gharo. One important example is the 50 MW HydroChina Dawood Wind Farm at Bhanbore, Gharo, which was completed in April 2017 and remains listed as operational by the official CPEC Secretariat. (CPEC)
Another Gharo project, Tenaga Generasi, has a gross capacity of 49.5 MW, according to Pakistan’s Private Power & Infrastructure Board.
So we already know one important thing:
Gharo is not just a place where people think wind might work. Commercial wind farms have actually been developed there. Wind Turbine in Pakistan
How Do We Know How Windy Gharo Is?
Pakistan Meteorological Department carried out a detailed wind study in Gharo.
For three years, from approximately April 2002 to March 2005, wind speed and direction were recorded at 10 metres and 30 metres.
The researchers then estimated wind conditions at 50 metres using standard wind-height calculation methods. (Pakistan Meteorological Department)
This distinction is important:
| Height | Type of data |
|---|---|
| 10 m | Measured |
| 30 m | Measured |
| 50 m | Calculated from measured data |
The study is old, so it should not be treated as today’s exact wind speed at every property in Gharo. However, it is extremely useful because it gives us three years of actual local measurements and clearly shows the wind pattern of the area.
For a new project today, the historical PMD data should ideally be combined with modern wind maps and fresh on-site measurements. World Bank/ESMAP also maintains newer wind-resource datasets and Pakistan wind maps based on the Global Wind Atlas. (EnergyData)
Average Wind Speed in Gharo
Here is one of the most important results from the PMD study.
| Height | Annual Average Wind Speed |
|---|---|
| 10 m | 3.6 m/s |
| 30 m | 5.6 m/s |
| 50 m | 6.6 m/s |
This table teaches us a very important lesson.
Height Makes a Huge Difference
At only 10 metres:
3.6 m/s
At 50 metres:
6.6 m/s
The wind speed has increased by around 83%.
But wind power does not increase only 83%.
Wind power depends approximately on:
That small “3” is extremely important.
If we compare 6.6 m/s with 3.6 m/s:
This means the moving air at 50 metres can theoretically contain roughly six times as much power per square metre as the air moving at 3.6 m/s, before turbine efficiency is considered.
The PMD’s measured and calculated wind-power-density results show the same effect very clearly.
Wind Power Density in Gharo
Wind power density tells us roughly how much wind energy passes through each square metre.
Think of it like rainfall.
Knowing that it rains is useful, but knowing how much rain falls is much more useful.
Wind power density works in a similar way.
| Height | Annual Wind Power Density |
|---|---|
| 10 m | 110.2 W/m² |
| 30 m | 232.7 W/m² |
| 50 m | 359.5 W/m² |
PMD classified the 50-metre result as moderate Class 3 wind-power potential under the classification used in that study.
Notice what happens:
The turbine has not changed.
The location has not changed.
Only the height has changed.
Yet the available wind resource increases dramatically.
That is one reason why a good tower can sometimes be more valuable than simply buying a bigger turbine. Wind Turbine Price in Gharo- Sindh Pakistan
Gharo Wind Speed Month by Month
Gharo does not have the same wind throughout the year.
PMD’s three-year averages show a very strong seasonal pattern.
Monthly Average Wind Speed
| Month | 10 m | 30 m | 50 m |
|---|---|---|---|
| January | 1.8 m/s | 3.6 m/s | 4.6 m/s |
| February | 2.0 | 3.9 | 4.9 |
| March | 2.3 | 4.2 | 5.2 |
| April | 4.3 | 6.3 | 7.4 |
| May | 5.9 | 8.2 | 9.4 |
| June | 6.2 | 8.3 | 9.3 |
| July | 5.9 | 8.0 | 9.1 |
| August | 5.7 | 7.7 | 8.8 |
| September | 5.0 | 6.8 | 7.8 |
| October | 1.7 | 3.5 | 4.4 |
| November | 1.2 | 3.0 | 3.8 |
| December | 1.4 | 3.5 | 4.5 |
| Annual average | 3.6 | 5.6 | 6.6 |
This table tells the story of Gharo better than almost anything else.
Which Months Are Best for Wind Turbines in Gharo?
The strongest period is roughly:
April to September
At 50 metres, the historical average wind speed was:
- April — 7.4 m/s
- May — 9.4 m/s
- June — 9.3 m/s
- July — 9.1 m/s
- August — 8.8 m/s
- September — 7.8 m/s
May was the strongest month in the three-year average, reaching 9.4 m/s at 50 metres.
The weakest month was November, at approximately 3.8 m/s at 50 metres.
For a 14-year-old student, you can think of Gharo like this:
In summer, the wind turbine gets a much bigger “fuel supply.”
In winter, its fuel supply becomes smaller.
Unlike a diesel generator, the fuel is free—but we cannot control when nature supplies it.
How Big Is the Difference Between May and November?
This is where wind energy becomes really interesting.
At 50 metres:
May:
November:
Because wind energy depends roughly on the cube of velocity:
So the moving air in May can contain roughly 15 times as much theoretical power as the moving air in November at those average speeds.
The PMD power-density data show this seasonal difference too.
| Month | Wind Power Density at 50 m |
|---|---|
| January | 139.3 W/m² |
| February | 162.0 |
| March | 167.4 |
| April | 363.7 |
| May | 712.0 |
| June | 730.4 |
| July | 685.4 |
| August | 575.6 |
| September | 420.6 |
| October | 125.9 |
| November | 110.0 |
| December | 146.4 |
| Annual | 359.5 W/m² |
June had the highest three-year average wind power density at approximately 730 W/m² at 50 metres.
What Time of Day Is Wind Strongest in Gharo?
Wind also changes during the day.
The PMD three-year data show that Gharo’s wind generally becomes stronger after the morning and reaches its strongest levels during the afternoon.
At 50 metres, the annual average hourly pattern increased from around 5.7–6.1 m/s during the early morning to approximately 7.9 m/s around 4 PM, before gradually decreasing later in the evening. (Pakistan Meteorological Department)
So a simple picture looks like this:
| Time | General Gharo Wind Pattern |
|---|---|
| Early morning | Lower |
| Late morning | Increasing |
| Afternoon | Strong |
| Around 4–5 PM | Often strongest |
| Evening | Starts decreasing |
| Night | Moderate/lower |
During June to August, PMD found even stronger afternoon conditions at 50 metres, with seasonal diurnal values rising above 10 m/s during parts of the day.
Where Does the Wind Come From?
Wind direction is also important.
PMD’s three-year wind rose at 30 metres showed that the most common wind direction was:
West-Southwest
The same analysis reported a mean wind speed of about 6.18 m/s from its wind-rose dataset at 30 metres, with wind below 2 m/s only around 15% of the time. (Wind Turbine in Hyderabad)
Why should a small wind-turbine owner care about direction?
Imagine a large building stands west-southwest of your turbine.
If most of the useful wind comes from that direction, the building can block and disturb it.
So even inside Gharo, two properties may produce very different results.
Is Gharo Good for a Small Home Wind Turbine?
The short answer is:
Potentially yes—especially at an open site with a properly elevated turbine.
But the PMD data teach us something very important.
At 10 metres, annual average wind was only:
3.6 m/s
At 30 metres:
5.6 m/s
At 50 metres:
6.6 m/s
So simply buying a wind turbine and putting it on a short pole near a building may waste much of Gharo’s wind advantage.
A turbine needs access to clean, unobstructed wind.
What Size Wind Turbine Could Be Used in Gharo?
Gharo’s wind resource does not automatically tell us whether you need 1kW, 3kW or 10kW.
The turbine size depends on:
your electricity consumption + hub-height wind + the turbine’s real power curve.
Here is a simple starting guide.
| Turbine Size | Possible Use in Gharo |
|---|---|
| 500W–1kW | Battery charging, lights, CCTV, small hybrid system |
| 1–2kW | Small house, solar-wind hybrid support |
| 2–3kW | Medium home or farmhouse |
| 3–5kW | Larger home, farm, workshop |
| 5–10kW | Large property or small commercial load |
| 10kW+ | Requires detailed engineering and resource assessment |
This is not a final sizing recommendation.
For example, one 3kW turbine may have a large rotor and excellent power curve, while another “3kW” turbine may have a small rotor and exaggerated manufacturer rating.
How Much Electricity Could a Turbine Produce?
We cannot calculate an accurate answer from Gharo’s average wind speed alone.
We need the actual turbine’s power curve.
However, here is an educational example showing how capacity factor changes energy output.
Illustrative Energy Production
| Turbine Rating | At 15% Capacity Factor | At 20% | At 25% | At 30% |
|---|---|---|---|---|
| 1kW | 1,314 kWh/yr | 1,752 | 2,190 | 2,628 |
| 2kW | 2,628 | 3,504 | 4,380 | 5,256 |
| 3kW | 3,942 | 5,256 | 6,570 | 7,884 |
| 5kW | 6,570 | 8,760 | 10,950 | 13,140 |
| 10kW | 13,140 | 17,520 | 21,900 | 26,280 |
These numbers are mathematical examples, not Gharo production guarantees.
For instance:
That averages roughly:
But actual output might be higher or lower depending on the rotor, power curve, tower, site and downtime.
Why Can’t We Just Use 6.6 m/s and Calculate the Output?
Because average wind speed hides information.
Imagine two days:
Day A:
- half the day = 2 m/s
- half the day = 10 m/s
Day B:
- all day = 6 m/s
Both might have a similar average.
But a wind turbine may produce very different amounts of electricity because wind power changes with the cube of wind speed.
PMD itself explains that average wind speed alone can hide important information and that the frequency distribution of wind speeds should be combined with the turbine’s power curve to estimate energy production.
This is why serious wind-energy analysis uses:
rather than only average wind speed.
Why Gharo’s Summer Wind Is Valuable
Gharo has another interesting advantage.
The strongest wind occurs during the hot part of the year.
April to September includes months when electricity demand in Sindh can also be high because of:
- fans,
- air conditioning,
- refrigeration,
- water pumping,
- agricultural loads. https://windturbine.pk/blog/wind-turbine-in-karachi-complete-buying-guide-2026-2027/
This does not mean wind generation will perfectly match electricity demand every hour, but the seasonal timing can be useful.
For homes and businesses, wind can also be combined with solar.
Solar + Wind in Gharo
Imagine a solar panel and a wind turbine as two students doing a group project.
The solar panel works best when sunlight is available.
The turbine works whenever there is enough wind—including periods when the sun is weaker or has already set.
A hybrid system can therefore use:
In Gharo, the strong afternoon and seasonal wind pattern makes wind-solar hybrid analysis particularly interesting.
But the exact system must be designed using real load data rather than simply buying the same number of kilowatts of wind and solar.
Should the Turbine Be Installed on the Roof?
Not automatically.
Gharo may be windy, but the air around buildings can become messy and turbulent.
Imagine water flowing smoothly through a canal.
Now place large rocks in the canal.
Behind the rocks, the water swirls.
Buildings and trees do something similar to wind.
A rooftop turbine may experience:
- turbulent wind,
- vibration,
- rapidly changing wind direction,
- lower output,
- additional building loads.
An open ground-mounted tower often gives the rotor access to smoother air.
Why Tower Height Is Especially Important in Gharo
The historical Gharo numbers make the lesson very clear:
| Height | Annual Wind Speed | Annual Power Density |
|---|---|---|
| 10 m | 3.6 m/s | 110 W/m² |
| 30 m | 5.6 m/s | 233 W/m² |
| 50 m | 6.6 m/s | 360 W/m² |
This does not mean every small turbine should be placed on a 50-metre tower.
Small 1–5kW turbines often use much shorter towers.
It means:
Before deciding the turbine size, investigate whether a taller tower gives enough extra wind to justify its cost.
What Should Be Checked Before Installing a Wind Turbine in Gharo?
For a serious project, I would check these seven things:
- Exact GPS coordinates of the property.
- Long-term wind-resource maps.
- Wind at proposed hub height.
- Nearby buildings, trees and terrain.
- Actual turbine rotor diameter and power curve.
- Tower, foundation, corrosion and lightning design.
- Electricity demand and whether the system is grid-connected, battery-based or hybrid.
The World Bank’s Pakistan wind-resource dataset provides modern wind maps derived from the Global Wind Atlas, while its separate Pakistan measurement dataset contains mast measurements from several regions for broader validation work.
What About Strong Winds and Storms?
A turbine that enjoys strong wind must also survive it.
For Gharo, buyers should not look only at:
“How much power does it produce?”
They should also check:
| Safety Specification | Why It Matters |
|---|---|
| Survival wind speed | Structural strength |
| Maximum rotor RPM | Prevents overspeed |
| Electromagnetic brake | Electrical braking |
| Furling / side deviation | Reduces wind load |
| Dump load | Absorbs excess electricity |
| Tower design | Resists overturning |
| Foundation | Transfers loads safely |
| Lightning protection | Protects equipment |
| Corrosion protection | Important in coastal Sindh |
A 3kW turbine with an impressive generator but weak tower or poor braking is not a good wind-energy system.
Coastal Corrosion in Gharo
Gharo’s proximity to the coastal region means wind is not the only environmental factor.
Moisture and salty air can accelerate corrosion. Wind Turbine Price in Pakistan
For long-term installations, equipment should be checked for:
- hot-dip galvanization,
- protective coatings,
- sealed bearings,
- stainless or corrosion-protected fasteners,
- weatherproof connectors,
- regular inspection.
A turbine may have a 20-year claimed design life, but that claim only matters if maintenance and corrosion protection are appropriate for the real environment.
Commercial Wind Power Proves Gharo Has a Real Resource
One useful way to explain Gharo’s importance to a student is this:
If a place had no useful wind, companies would not invest millions of dollars building large wind farms there.
The official CPEC project database confirms a 50 MW operational wind farm at Gharo, and PPIB also lists a separate 49.5 MW wind project at Gharo.
At the wider provincial level, the Sindh Energy Department says the Gharo–Keti Bandar corridor is around 60 km wide and over 180 km long. Its current website reports 36 operational wind IPPs totaling 1,845 MW across Sindh’s wind development.
That does not mean every household in Gharo should install a turbine.
But it is strong evidence that the region deserves serious wind-energy consideration.
What Did We Learn?
Gharo is a very useful real-world science lesson.
The same area can have:
- weak wind close to the ground,
- much stronger wind higher up,
- very strong wind during summer,
- much weaker wind during winter.
The PMD three-year study found approximately:
| Key Gharo Finding | Result |
|---|---|
| Annual average at 10 m | 3.6 m/s |
| Annual average at 30 m | 5.6 m/s |
| Annual average at 50 m | 6.6 m/s |
| Highest monthly average at 50 m | 9.4 m/s in May |
| Lowest monthly average at 50 m | 3.8 m/s in November |
| Annual wind power density at 50 m | 359.5 W/m² |
| Dominant direction | West-Southwest |
| Strongest general season | April–September |
The biggest lesson is:
A wind turbine does not produce electricity simply because a place is called windy. Good wind-energy design means putting the right turbine, at the right height, in the right place. https://windturbine.pk/blog/home-wind-turbine-price-in-pakistan/
Is a Wind Turbine Worth Considering in Gharo?
Yes. Gharo is one of the more promising areas in Pakistan for wind-energy investigation.
Historical PMD measurements show a strong wind season and significantly better resources as height increases. The existence of operational commercial wind farms provides additional real-world evidence of the region’s wind potential. https://windturbine.pk/blog/wind-turbine-in-gadap-town-karachi/
However, for a home, farmhouse or small business, do not simply buy a 1kW, 3kW or 5kW turbine because Gharo is in a wind corridor.
First measure or model the exact site, determine the required tower height, obtain the turbine’s genuine power curve, and calculate how many kilowatt-hours per year it is likely to produce.
That is how a student turns the simple idea of “wind makes electricity” into real wind-energy engineering.Gharo
