Sindh to generate 2000 MW at its wind corridor in next two years

[I S I]

LOL. Billi ke khuwaab main cheechrey. Wind power nahiin, PeePeePee waale bus g..d se power bana sakta hain.

Per the latest published data as of end 2016 total Wind power generation capacity installed in Pakistan is 591MW.

However it must be clearly understood that the above is maximum capacity. Wind turbine design varies so it is difficult to work out exact capacity factor for each plant. As a rule of thumb, power generation starts at the wind speed of about 4 meter per second (9 MPH) with maximum power produced at wind speed of about 15 meter per second (34 MPH). At gale force wind speeds say 50 MPH the turbine will shut down to prevent damage. The capacity factor is normally about 25% of the installed capacity onshore and about 40 per cent off-shore. Therefore actual wind power output on the annualised basis in Pakistan as of end 2016 would be 150 MW at best.

(Capacity factor of conventional power stations can be as high as 80% for the state of the art combined cycle plants. No plant produces 100% of its capacity due to stoppages & maintenance).

Sindh to generate 2000 MW at its wind corridor in next two years

Monday, January 21, 2013 - Karachi—Sindh government is working on 40 different power projects in its wind corridor, with a total generation capacity of 2000 MW in next two years, said Mir Hussain Ali, provincial Secretary for Environment and Alternate Energy Department.

This will also allow the electrification of about 120 schools in rural Sindh, he said addressing a session on the Renewable Energy organized by IUCN - Pakistan on Sunday.

Talking about the opportunities in the wind corridor, he said, that the government is working on about 40 projects with various investors with total generation capacity of 2000 MW in the next two years.

“This is despite the fact that Renewable Energy projects often do not get a green light in public sector because of the initial costs,” he said. The Sindh secretary for environment and alternative energy said the government is also supplying solar stoves and working on a biogas project worth Rs. 200 million rupees.

The secretary for environment and alternative energy mentioned that in Mirpurkhas, Solar Water Pumping Stations have been installed to meet the electricity crunch.

Mir Hussain Ali also talked about having immense potential of biogas at the Cattle Colony in Karachi and prospects in coastal areas of Pakistan in lieu of wind related projects.

On the occasion Carl Pope, a renowned expert on renewable energy in his presentation, “Renewable Energy Cheaper in the Long Run,” said that presently over 1.3 billion people in the world are estimated to be living without electricity.

One billion of these people, including 700 million residents of South Asia will remain without electricity until 2030 if the switch to alternatives does not happen, he warned.—Agencies

Bullshit. Please leave this country in two years and we will make everything well

Bhai 3 years ho gaye..

let them work yaar we need power 5000mw and gov is doing something for it at least .

I am reminded of an old story where Punjab and Haryana politicos would condemn dams being built on Himachal rivers. They wud say " paani se bijlee nikal kar dete hain" saying that such de-electrified water was affecting soil fertility!

Niaz sb,

These days they build wind turbines with higher hub heights and much larger (and more aerodynamic blades). In some locations in India they are generating close to 35% PLF already, it is claimed that they could hit 40% as well. The 40% sites being cited are mainly in Gujarat, presumably it should be possible to get similar PLFs in coastal Sindh and B'stan as well.

The problem isn't just production but horrible collection in interior-Sindh. The primary reason why they're building transmission lines for dispatching Thar's power output to Punjab and Karachi. No power producer would like to operate with low collection Dispatch companies since sluggish collection disturbs the operating and cash cycle of producers, resulting in what we call circular debt.

There's a lot of potential for bio gas generation in almost all main cities, here in Lahore I often see milk men driving horse carts full of dung and just throwing it in open space away from main city. The stuff could be collected and used for bio gas generation. Or maybe plants could be placed near gawala colonies so to make things even easier.

Naeem bhai,

There's a lot of potential for bio gas generation

Is this what ISI sb had in mind when he said "PeePeePee waale bus g..d se power bana sakta hain."

Honourable SoulSpokeman,

The data from the European Wing Energy Association (EWEA- 2008) which is based upon average experience in the Europe as a whole gives CF of only 21%. Actual capacity factor will of course differ from place to place depending upon average annual wind speed and the design of the wind turbine. Low European average could be because of presence of large number of old wind turbines and the “Shadowing”.

Shadowing refers to the fact that presence of other wind turbines nearby affects the speed and direction of the wind striking the turbine blades. According to a research paper, even though a 2 MW turbine would generate 2 MW at the wind speed of around 15 meter per second; a cumulative wind farm of say 50 units would only produce about 92 MW at peak wind speed. This is primarily because to save on land costs turbines are installed close to one another.

However I agree that most new wind turbine designers these days boast 35 % capacity factor.
In the absence any reliable date I used an approximation in my earlier post.

Niaz sb,

That is true. Spacing and placement is very critical both in wind turbines and solar panels. It is as much an art as a precise science as local conditions have to be kept in mind.
