NASA POWER Wind Data for Pakistan: How to Check Wind Speed at Your Location

Before buying a wind turbine in Pakistan, one question matters more than turbine wattage, blade colour, generator size or even price: NASA POWER Wind Data for Pakistan: How to Check Wind Speed. NASA POWER wind data Pakistan

How much usable wind is actually available at the height where the turbine rotor will operate?

A turbine advertised as 1kW, 3kW, 10kW or 50kW cannot produce meaningful energy if it is installed at a poor wind site. Conversely, a properly selected turbine on a good tower at a strong wind location can outperform a much larger turbine installed in turbulent or weak wind.

NASA’s POWER — Prediction Of Worldwide Energy Resources platform is one of the most useful free tools for carrying out the first stage of a wind-resource assessment in Pakistan.

NASA POWER provides global meteorological data based mainly on NASA’s MERRA-2 atmospheric reanalysis. It offers wind-speed information at standard heights and can also calculate wind speed at user-defined heights between 10 and 300 metres. However, NASA itself cautions that these wind values represent the mean flow of a region, not the exact airflow around an individual house, tree, hill or rooftop. (POWER)

This distinction is fundamental.

1. What Is NASA POWER?

NASA POWER is a free global environmental-data service operated by NASA’s Langley Research Center. NASA POWER wind data Pakistan

POWER provides solar and meteorological data for renewable energy, buildings and agricultural applications. Its meteorological datasets are primarily derived from the Modern-Era Retrospective Analysis for Research and Applications, Version 2 — MERRA-2, developed by NASA’s Global Modeling and Assimilation Office. NASA POWER wind data Pakistan

MERRA-2 combines atmospheric modelling with observations from sources including:

surface weather observations;
ocean wind measurements;
upper-air measurements;
aircraft observations;
radiosondes;
satellite remote sensing.

NASA states that its MERRA-2 meteorological fields are produced on a global grid approximately 0.5° latitude × 0.625° longitude. Wind values therefore represent the average conditions of a relatively large grid cell rather than the exact wind at a particular rooftop. (POWER)

This explains both the strength and limitation of NASA POWER.

It can tell you:

“This region has a promising wind climate.”

It cannot necessarily tell you:

“The wind above this particular 30-foot house will average exactly 5.7 m/s.”

2. What Wind Data Does NASA POWER Provide?

NASA POWER provides standard wind-speed parameters at 10m and 50m for its main user communities. Its underlying MERRA-2 archive also contains wind at other reference levels, and the POWER API can calculate corrected wind speed for a user-defined height between 10m and 300m. (POWER)

For small and medium wind turbines, this is extremely useful because rotor hub height may be:

10m;
12m;
18m;
20m;
24m;
30m;
40m;
50m.

For larger 50–100kW installations, the hub may be higher still.

Important NASA wind parameters

Parameter	What it tells you	Wind-turbine use
Wind speed at 10m	Near-surface regional wind	Initial screening
Wind speed at 50m	Elevated regional wind	Better indication for tower-mounted systems
Custom-height wind	Estimated wind at 10–300m	Match data to actual hub height
Wind direction	Direction wind comes from	Turbine positioning
Hourly data	Hour-by-hour wind	Power-curve/AEP studies
Daily data	Daily average behaviour	Weather and seasonal analysis
Monthly data	Monthly average	Seasonal comparison
Annual data	Annual resource	Long-term screening
Climatology	Multi-year mean behaviour	Site-to-site comparison

NASA’s hourly API provides average values by hour and supports CSV, JSON, ASCII and NetCDF outputs. Hourly UTC and Local Solar Time data are available from 2001 to near real time, while broader MERRA-2 meteorological coverage extends back to 1981 for appropriate temporal products.

3. Why Height Matters So Much for Wind Turbines

A common mistake in Pakistan is to check a weather application showing:

Wind = 15 km/h

and then use that number to predict turbine production.

That is not enough.

You must know:

At what height was that wind speed measured or modelled?

Wind near the ground is slowed by:

buildings;
walls;
trees;
vegetation;
terrain;
ground friction.

As elevation increases, wind generally becomes faster and smoother.

NASA POWER uses the following relationship for custom-height corrected wind speed:

[
V_h=V_{50}\left(\frac{h}{50}\right)^\alpha
]

Where:

(V_h) = estimated wind speed at the desired height;
(V_{50}) = wind speed at 50m;
(h) = requested turbine height;
(\alpha) = wind-shear parameter associated with surface roughness.

NASA’s custom-height service supports heights between 10m and 300m. (POWER)

4. NASA POWER Wind Height Table

For wind-turbine projects, I would normally check these heights:

Height	Why check it?	Typical relevance
10m	Standard reference level	Very small towers / baseline
12m	Common small-turbine tower	1–5kW
15m	Improved small wind	1–10kW
18m	Good small-wind tower level	3–20kW
20m	Useful small-commercial height	5–20kW
24m	Better exposure	5–30kW
30m	Strong small/commercial benchmark	10–50kW
40m	Commercial-scale assessment	20–100kW
50m	Native NASA POWER wind level	Excellent comparison level
80m	Larger turbine assessment	Commercial wind
100m	Utility-style resource comparison	Large turbines
150m	Modern large-turbine studies	Utility scale
200m	High hub-height analysis	Utility scale
300m	Upper NASA custom-wind limit	Research/resource analysis

For the 1kW–100kW market, 10–50m is usually the most relevant range.

5. Example: Why You Cannot Ignore Tower Height

Suppose NASA POWER gives:

Wind speed at 50m = 5.5 m/s

Using the common wind power-law equation, the estimated speed at other heights changes depending on wind shear.

The following is an illustrative engineering example, not a NASA forecast for a particular Pakistan site. A shear exponent of 0.14 is a commonly used open-terrain approximation, while higher values can occur over rougher terrain; U.S. Department of Energy studies note that wind-shear exponents vary significantly with surface conditions. (The Department of Energy’s Energy.gov)

Height	Example α = 0.14	Example α = 0.20
10m	4.39 m/s	3.99 m/s
20m	4.84 m/s	4.58 m/s
30m	5.12 m/s	4.97 m/s
50m	5.50 m/s	5.50 m/s
80m	5.87 m/s	6.04 m/s
100m	6.06 m/s	6.32 m/s
150m	6.41 m/s	6.85 m/s
200m	6.68 m/s	7.26 m/s
300m	7.07 m/s	7.87 m/s

Do not blindly apply α = 0.14 to every Pakistan site. NASA’s custom-height feature allows the selected surface type to influence the correction. 2 KW wind Turbine in Pakistan NASA POWER wind data Pakistan

6. Why a Small Increase in Wind Speed Is a Big Deal

Available wind power is proportional to:

[
P=\frac12\rho A V^3
]

Notice:

[
V^3
]

Wind speed is cubed.

The U.S. Department of Energy highlights this relationship when explaining small-wind performance. (The Department of Energy’s Energy.gov)

Consider two turbine heights:

Lower tower

[
V=5m/s
]

Taller tower

[
V=6m/s
]

Wind-power ratio:

[
\left(\frac{6}{5}\right)^3
=1.728
]

So increasing wind speed by just:

20%

increases theoretical available wind power by approximately:

73%.

This is why spending money on a better tower can sometimes be far more valuable than buying a larger generator.
NASA POWER wind data Pakistan

7. Pakistan Example Using NASA POWER Data

A 2025 peer-reviewed study used hourly NASA POWER wind data for six Pakistani coastal locations during 2023, examining both 10m and 50m heights. The authors studied Gwadar, Jiwani, Karachi, Keti Bandar, Ormara and Pasni. (Nature)

The approximate mean values presented in the study’s figures are: NASA POWER wind data Pakistan

Location	10m mean wind	50m mean wind	Increase with height
Gwadar	4.40 m/s	4.93 m/s	~12%
Jiwani	4.22 m/s	4.81 m/s	~14%
Karachi	4.57 m/s	5.59 m/s	~22%
Keti Bandar	5.02 m/s	6.30 m/s	~25%
Ormara	4.48 m/s	5.46 m/s	~22%
Pasni	3.94 m/s	4.94 m/s	~25%

The study specifically reports a range of 3.94–5.02 m/s at 10m and 4.93–6.30 m/s at 50m, with Keti Bandar at the upper end. (Nature)

Important warning

These are 2023 values, not a 20-year climatology.

They demonstrate the method and the importance of height; they should not be interpreted as a guaranteed long-term production forecast.

8. What the Pakistan Height Data Really Tells Us

Look at Karachi:

[
4.57m/s\rightarrow5.59m/s
]

Wind speed increases approximately:

22%

But because available wind energy approximately follows (V^3):

[
\left(\frac{5.59}{4.57}\right)^3\approx1.83
]

That represents roughly 83% more theoretical wind power passing through the same rotor area, before considering turbine efficiency and other losses.

For Keti Bandar:

[
5.02\rightarrow6.30m/s
]

The theoretical wind-power ratio is nearly:

[
1.98
]

or approximately twice the wind power density.

This calculation is an engineering inference from the reported NASA-derived wind speeds and the standard wind-power relationship; it does not mean a turbine will literally produce twice the electricity. (Nature)

That depends on the turbine’s actual power curve.

9. NASA POWER Surface Types Matter

NASA allows the custom-height calculation to account for different surface categories.

Some available NASA surface aliases include: (POWER)

NASA surface	Description	Possible Pakistan example
`openwater`	Open water	Offshore/coastal reference
`vegtype_11`	Rough bare soil	Balochistan/open arid terrain
`vegtype_9`	Low shrubs with bare soil	Semi-arid land
`vegtype_7`	Perennial ground cover	Open grass-covered site
`vegtype_12`	Crop/wheat terrain	Agricultural regions
`airportgrass`	Flat rough grass	Very open flat ground

These are NASA model classifications, not exact descriptions of every Pakistan site.

A farmhouse in Gadap, for example, may contain:

houses;
boundary walls;
trees;
water tanks;
farmland;
hills.

No single NASA surface model will perfectly reproduce all those obstacles.

This is why NASA should be treated as regional screening data.

10. How to Check Your Exact Location in NASA POWER

NASA provides an interactive application called the Data Access Viewer — DAV.

NASA’s official workflow is straightforward. (POWER)

Step 1 — Open NASA POWER Data Access Viewer

Go to NASA POWER’s Data Access Viewer.

Select a single-point analysis rather than an entire country or region when studying a turbine location.

Step 2 — Choose Renewable Energy

NASA divides POWER into user communities.

Choose:

Renewable Energy — RE

This ensures that the available parameters and units are appropriate for energy-resource analysis. 3 KW Wind Turbine in Pakistan

Step 3 — Select Your Location

NASA allows two methods:

Method A — Click on the map

Zoom into Pakistan and select your site.

Method B — Enter latitude and longitude

This is better for serious wind assessment.

For example, obtain coordinates from: NASA POWER wind data Pakistan

Google Maps;
GPS;
your phone;
site survey coordinates.

NASA accepts decimal-degree latitude and longitude. (POWER)

For a customer wind-turbine assessment through WindTurbine.pk, GPS coordinates are much more useful than simply saying “Karachi” or “Gwadar.”

11. Choose the Correct Time Period

Do not evaluate a wind-turbine site from one windy month.

For initial assessment I recommend examining:

Level 1 — Long-term climatology

Use this to answer:

Is the location generally windy?

Level 2 — Monthly data

Use this to identify:

strong months;
weak months;
monsoon contribution;
seasonal variation.

Level 3 — Hourly data

Use hourly data when carrying out serious turbine analysis.

Hourly wind tells you how often the turbine experiences:

<3m/s;
3–4m/s;
4–5m/s;
5–6m/s;
6–8m/s;
8–10m/s;
10m/s.

NASA offers hourly, daily, monthly/annual and climatological temporal products. Wind Turbine in hawksbay-paradise-point and Gadani

12. Which NASA Temporal Data Should You Use?

NASA data	Use it for
Climatology	Quick location screening
Annual	Year-to-year comparison
Monthly	Seasonal analysis
Daily	Weather patterns
Hourly	Actual turbine-energy modelling

If I were assessing a 10kW turbine, I would never stop at annual average wind speed.

I would download hourly data.

13. Why Average Wind Speed Alone Is Not Enough

Consider two sites.

Site A

Average:

5.5m/s

Wind is relatively steady around 4–7m/s.

Site B

Average:

5.5m/s

But it spends:

many hours at 1–3m/s;
occasional periods at 12–15m/s.

Both have the same average.

Their turbine output can be very different.

This happens because:

[
P\propto V^3
]

and because every turbine has a power curve.

Therefore you need a wind-speed frequency distribution, not just a mean.

14. Wind-Speed Frequency Table You Should Create

After downloading hourly NASA data, divide the observations into bins.

For example:

Wind speed	Hours/year	Percentage	Turbine implication
0–2 m/s	—	—	Essentially no generation
2–3 m/s	—	—	Rotor may start
3–4 m/s	—	—	Very low output
4–5 m/s	—	—	Low production
5–6 m/s	—	—	Useful wind
6–7 m/s	—	—	Good production
7–8 m/s	—	—	Strong production
8–10 m/s	—	—	High production
10–12 m/s	—	—	Approaching rated output for many turbines
>12 m/s	—	—	Strong/rated region depending on turbine

Then match this table with your turbine’s manufacturer power curve.

15. How to Calculate Turbine Energy from NASA Hourly Wind Data

Suppose your turbine power curve says:

Wind speed	Turbine output
3 m/s	50 W
4 m/s	150 W
5 m/s	350 W
6 m/s	700 W
7 m/s	1.2 kW
8 m/s	2.0 kW
9 m/s	3.2 kW
10 m/s	4.8 kW
11 m/s	7.0 kW
12 m/s	10 kW

These numbers are only an example.

If NASA shows 1,000 hours/year around 7m/s:

[
1.2kW\times1000h

1,200kWh
]

Repeat for every wind-speed bin.

Then:

[
AEP=\sum(P_i\times H_i)
]

Where:

AEP = annual energy production;
(P_i) = turbine output at a wind speed;
(H_i) = annual hours in that wind-speed range.

This is far better than:

10kW × 24 hours × 365 days

which would incorrectly assume that the turbine operates at full rated power continuously.

16. Example: Rated Power vs Annual Energy

A 10kW turbine has a theoretical maximum:

[
10\times8760

87,600kWh/year
]

But suppose actual annual production is:

[
17,500kWh
]

Capacity factor becomes:

[
CF=\frac{17,500}{87,600}
]

[
CF\approx20%
]

So although the machine is called a 10kW turbine, its year-round average electrical output would be:

[
17,500/8760
\approx2.0kW
]

This is completely normal.

17. How I Would Interpret NASA Wind Speed for Small Turbines

For an initial screening only, the following classification is useful: https://windturbine.pk/

Average wind at actual hub height	Initial assessment
Below 3 m/s	Very poor
3–4 m/s	Weak
4–5 m/s	Marginal/moderate
5–6 m/s	Promising
6–7 m/s	Good
7–8 m/s	Very good
Above 8 m/s	Excellent resource, but structural/extreme-wind assessment important

DOE’s small-wind consumer guidance uses approximately 4 m/s annual average wind speed at hub height as a basic threshold for a site to be considered for small wind. That is a minimum screening value—not a guarantee that a turbine will be economically attractive. (The Department of Energy’s Energy.gov)

For commercial viability, I would generally become much more interested once long-term hub-height wind moves toward 5–6m/s or higher.

18. Do Not Compare Different Sites at Different Heights

Suppose:

Karachi

NASA wind:

5.6m/s at 50m

Lahore

NASA wind:

4.7m/s at 10m

You cannot directly conclude that Karachi is 19% windier.

The heights are different.

Always compare:

10m vs 10m

or:

30m vs 30m

or:

50m vs 50m.

For turbine selection, the best comparison is:

wind speed at the proposed hub height. https://windturbine.pk/prices-of-wind-turbine-in-pakistan/

19. What Height Should You Use for a 1–100kW Turbine?

A practical starting framework:

Turbine rating	Data height I would investigate
500W–1kW	10–15m
1–3kW	12–20m
3–5kW	15–24m
5–10kW	18–30m
10–20kW	20–40m
20–50kW	30–50m
50–100kW	40m+

These are assessment ranges, not structural design requirements.

Actual tower height should be selected according to:

rotor size;
manufacturer specifications;
obstacle height;
terrain;
extreme wind;
structural calculations;
planning limitations.

A taller tower is not automatically structurally safe.

20. NASA Data for Rooftop Wind Turbines

This deserves special attention.

Imagine NASA shows:

[
5.5m/s
]

at your Karachi coordinates.

You have a 10m-high house.

But around it are:

15m houses;
water tanks;
trees;
boundary walls;
rooftop rooms.

Your actual turbine may experience highly turbulent wind.

NASA explicitly states that its wind parameters are intended for mean regional wind flow, rather than local effects created by buildings and topography. (POWER)

So:

NASA showing good wind does not automatically mean your rooftop is a good turbine site.

21. Why Rooftop Measurements Are Important

Two houses only 500m apart may have almost identical NASA POWER data.

But House A could be:

on the coastal edge;
open to southwest wind;
above surrounding buildings.

House B could be:

surrounded by five-storey buildings;
behind large trees;
shielded from prevailing wind.

NASA may treat them as essentially the same regional location.

The turbines will not.

22. NASA POWER + On-Site Anemometer = Better Method

My recommended approach for wind turbine projects in Pakistan is:

Stage 1

NASA POWER screening.

Stage 2

Global Wind Atlas comparison.

Stage 3

Satellite/topographic site review.

Stage 4

Physical site inspection.

Stage 5

Anemometer at or near proposed turbine height.

Stage 6

Analyse:

mean speed;
frequency distribution;
wind direction;
seasonal variation;
turbulence;
extreme winds.

Stage 7

Select the turbine.

Not the other way around.

23. Pakistan Has Ground-Based Wind Data Too

NASA is not the only useful resource.

The World Bank/ESMAP Renewable Energy Resource Mapping project installed 12 wind measurement masts across Pakistan and made the data available publicly. The measurements include wind speed, direction, air pressure, relative humidity and temperature.https://windturbine.pk/blog/home-wind-turbine-price-in-pakistan/

The Pakistan dataset includes sites such as:

Gwadar;
Sujawal;
Umerkot;
Bahawalpur;
Chakri;
Haripur;
Peshawar;

This is particularly valuable because it provides measured mast data, which can be used to help understand how regional models compare with real observations.

24. NASA POWER vs Global Wind Atlas vs Anemometer

They serve different purposes.

Tool	Best use	Main limitation
NASA POWER	Long-term meteorological screening	Coarse regional grid
Global Wind Atlas	Spatial wind-resource mapping	Still model-based
World Bank/ESMAP mast data	Ground validation in selected locations	Only available at measurement sites
Your own anemometer	Exact project-site analysis	Requires time and proper installation

The Global Wind Atlas provides mean wind speed and power-density layers at multiple heights and is another excellent screening tool. (Global Wind Atlas)

The best feasibility study uses multiple sources.

25. Recommended Workflow for Pakistan

Step 1 — Obtain GPS coordinates

Do not search only for:

Karachi

Use the actual property coordinates.

Step 2 — Check NASA 10m wind

This tells you the regional near-surface baseline.

Step 3 — Check NASA 50m wind

Compare 10m vs 50m.

If there is a large increase, tower height may have significant value.

Step 4 — Request actual turbine height

If your proposed hub is 18m:

Request 18m.

For 24m:

Request 24m.

NASA supports custom wind elevations between 10 and 300m. (POWER)

Step 5 — Examine monthly data

Create:

Month	Wind at hub height
January
February
March
April
May
June
July
August
September
October
November
December

This tells you when the turbine will produce most electricity.

26. Pakistan’s Seasonal Wind Is Important

A site with excellent wind from May to August but poor wind during the rest of the year may still be useful.

But the system design will differ from a location with steady year-round wind.

This becomes especially important with:

Wind + solar hybrid systems.

If wind production complements solar production, the combined renewable-energy profile can be far more valuable than analysing annual averages alone.

For hybrid-system planning, visit WindTurbine.pk.

27. Examine Hourly Wind

For serious analysis, download an hourly dataset.

Then ask:

What percentage of the year is below cut-in?

Suppose your turbine has:

[
V_{cut-in}=3m/s
]

and wind remains below 3m/s for 40% of the year.

The turbine may generate essentially nothing during those hours.

28. Do Not Confuse Start-Up Wind with Useful Wind

Chinese turbine datasheets often state:

Start-up wind speed = 1.5 m/s

This sounds attractive.

But rotor movement is not the same as useful electrical production.

NASA may show many hours between 2 and 4m/s.

You need the turbine’s power curve to determine what those hours are actually worth.

Ask the manufacturer for:

Wind speed	Required data
3 m/s	Watts
4 m/s	Watts
5 m/s	Watts
6 m/s	Watts
7 m/s	Watts
8 m/s	Watts
9 m/s	Watts
10 m/s	Watts
11 m/s	Watts
12 m/s	Watts

Without this table, NASA data cannot accurately predict turbine production.

29. Check Rotor Area Too

NASA tells you the wind resource.

It does not tell you whether the turbine manufacturer’s power claim is genuine.

Once you obtain wind speed, check:

[
P_{wind}=\frac12\rho A V^3
]

If a seller claims:

10kW at 12m/s

but the rotor intercepts only 4m² of wind, basic physics can reveal that the claim is impossible.

NASA wind data and rotor swept-area analysis should therefore be used together.

30. A Complete Wind Turbine Assessment Needs Four Datasets

Think of wind-turbine feasibility as four layers.

Layer 1 — Resource

NASA POWER / Global Wind Atlas:

How much wind exists?

Layer 2 — Site

Physical inspection:

Can that wind actually reach the turbine cleanly?

Layer 3 — Machine

Power curve:

How efficiently can the turbine convert that wind?

Layer 4 — Electrical load

Customer data:

Is the generated energy actually useful?

Only after all four should you select:

1kW;
2kW;
3kW;
5kW;
10kW;
20kW;
50kW;
100kW.

31. Common NASA POWER Mistakes

Mistake 1 — Using today’s wind

Wind turbines are 15–20-year assets.

One day is irrelevant.

Mistake 2 — Looking only at annual average

Distribution matters.

Mistake 3 — Using 10m data for a 30m tower

Always analyse hub height.

Mistake 4 — Ignoring buildings

NASA does not model your neighbour’s house.

Mistake 5 — Assuming average wind equals turbine output

You need a power curve.

Mistake 6 — Believing rated wattage

Verify swept area and performance.

Mistake 7 — Ignoring direction

Trees/buildings may block the dominant wind direction.

Mistake 8 — Ignoring seasonality

Monthly output can vary dramatically.

32. Is NASA POWER Accurate Enough to Buy a Wind Turbine?

For initial feasibility:

Yes.

For comparing two regions:

Yes.

For deciding whether to investigate wind further:

Absolutely.

For guaranteeing that a PKR 2 million turbine will produce a particular number of units:

No.

NASA itself says its wind products describe regional mean flow and do not resolve local effects of buildings and topography. (POWER)

For a substantial investment, NASA should be followed by:

site survey;
obstacle analysis;
tower-height assessment;
anemometer data where practical;
certified turbine power curve;
structural analysis;
electrical-system design.

33. How Much Wind Is “Good” for a Home Turbine?

A simple screening framework:

Below 4m/s

Wind is generally difficult to justify economically unless the turbine has a specific low-wind purpose.

4–5m/s

Possible, but turbine and site selection become critical.

5–6m/s

Much more interesting.

6–7m/s

Strong small-wind resource.

Above 7m/s

Potentially excellent, but turbine class, tower loads, braking and extreme-wind conditions become increasingly important.

Again, use these values at hub height, not street level.

34. Does NASA POWER Work Everywhere in Pakistan?

Yes, NASA POWER provides global data. NASA POWER wind data Pakistan

You can investigate locations such as:

Karachi;
Gwadar;
Hyderabad;
Keti Bandar;
Jhimpir;
Gharo;
Thatta; https://windturbine.pk/blog/wind-turbine-in-thatta-sindh/
Jamshoroo wind-turbine-in-jamshoro
Ormara;
Pasni;
Jiwani;
Gadani;
Hub;
Quetta;
Nok Kundi;
Islamabad;
Lahore;
Multan;
Bahawalpur;
Peshawar;
Hyderabad Wind Turbine in Hyderabad
Gilgit;
Chitral.

However:

Availability of NASA data does not mean all those locations are suitable for wind turbines.

It simply enables you to investigate them using the same methodology.

35. Coastal Pakistan Needs Special Attention

Coastal areas often attract wind-turbine projects because of sea-breeze circulation and open exposure.

But installation engineering must also account for:

salt;
humidity;
corrosion;
extreme wind;
lightning;
foundations;
tower coating;
stainless or protected fasteners;
sealed electrical equipment.

Good wind resource does not automatically mean easy installation.

36. Urban Karachi Needs a Different Method

For Karachi, NASA may show promising regional wind.

But there is a major distinction between: https://windturbine.pk/blog/wind-turbine-in-dha-karachi/

DHA / Clifton exposed coastal roof

and

Dense interior neighbourhood

and

Open land near the coastal belt

and

Industrial property surrounded by buildings.

Their NASA grid value may be similar.

Their actual rotor inflow may be completely different.

For urban installations, I would give much greater weight to site geometry and on-site measurements.

38. NASA POWER API for Advanced Users

You do not need programming knowledge to use NASA POWER.

However, engineers can access POWER through its REST APIs.

NASA’s API supports:

point requests;
hourly data;
daily data;

The API documentation states that custom wind elevation is available for point requests from 10m to 300m.

This means a future WindTurbine.pk calculator could automatically ask a customer for:

latitude + longitude + tower height

and then use NASA POWER data as one input to a preliminary wind assessment. NASA POWER wind data Pakistan

39. WindTurbine.pk NASA Calculator

A professional tool could ask:

Location

Latitude / longitude

Turbine

Rated power

Rotor diameter

Turbine type

HAWT / VAWT

Tower

Hub height

Power curve

Manufacturer data

Then automatically retrieve:

NASA 10m wind;
NASA 50m wind;
custom-height wind;
monthly wind;
hourly wind distribution.

And calculate:

expected hours above cut-in;
theoretical rotor power;
turbine expected AEP;
capacity factor;
monthly kWh;
estimated annual savings.

That would be much more valuable than a basic “10kW turbine generates 7,200 units/month” calculator.

For anyone asking:

“Can I install a wind turbine at my location in Pakistan?” NASA POWER wind data Pakistan

Use this sequence:

1. Get exact latitude and longitude.

2. Check NASA POWER long-term wind.

3. Compare 10m and 50m values.

4. Request the proposed hub height.

5. Examine monthly seasonality.

6. Download hourly wind data.

7. Analyse wind-speed distribution.

8. Check prevailing direction.

9. Cross-check with Global Wind Atlas.

10. Look for nearby World Bank/ESMAP measurements.

11. Inspect buildings, trees and terrain.

12. Measure wind on-site where the investment justifies it.

13. Obtain the turbine’s verified power curve.

14. Verify rotor swept area.

15. Calculate annual energy—not just rated watts.

16. Only then select the turbine and tower.

Conclusion

NASA POWER is one of the best free starting points for analysing wind turbine potential in Pakistan, but it becomes powerful only when it is used correctly.

The most important lessons are:

Use the exact coordinates.

Analyse wind at turbine hub height.

Do not rely only on annual average wind speed.

Use hourly wind distribution for serious energy calculations.

Cross-check model data with site conditions and measurements.

Never use NASA wind data alone to validate a manufacturer’s turbine wattage claim.

NASA POWER can tell us the wind resource.

The turbine power curve tells us how much of that resource the machine may convert.

The physical site tells us how much of that wind actually reaches the rotor.

And the combination of all three determines whether a wind turbine is a good investment.

Frequently Asked Questions

Is NASA POWER wind data free?

Yes. NASA POWER provides free global solar and meteorological datasets and tools. (POWER)

Does NASA POWER provide wind speed for Pakistan?

Yes. POWER is global, and users can select any Pakistan location using map coordinates. (POWER)

What heights are available?

Standard wind data are available at 10m and 50m for the main POWER communities, while custom corrected wind speed can be requested between 10m and 300m. NASA POWER wind data Pakistan

Should I use 10m or 50m wind for my turbine?

Neither automatically. Use the wind speed closest to your actual proposed turbine hub height or request a custom-height value.

Can NASA tell me exactly how much electricity my turbine will generate?

Not by itself. You also need the turbine’s power curve and site-specific conditions.

Is 5m/s wind good for a turbine?

Approximately 5m/s annual average wind at hub height can be a useful small-wind resource, but economic feasibility depends on turbine efficiency, rotor area, tower cost, electricity value and wind distribution. DOE uses 4m/s at hub height as a basic small-wind screening threshold. (The Department of Energy’s Energy.gov)

Is NASA data enough for a 50kW or 100kW project?

It is excellent for screening, but a project at that investment level should normally proceed to more detailed resource assessment, local measurements, structural engineering and verified turbine-performance analysis. Pakistan also has World Bank/ESMAP wind-mast datasets that can help with regional validation. (ESMAP)

Can NASA POWER analyse a rooftop?

It can provide the regional wind resource at that coordinate, but NASA states that local building and terrain effects are not represented in the regional mean-flow values. 10 KW Wind Turbine in Pakistan
