Introduction of Windmill Use to generate electric energyInstalled on a tower in windy locationAverage life span 25 to 30 yearsRuns on wind energy

Turbine is made up of Rotor with 1- 3 blades Gear boxShaftsGeneratorController Installed on a steel tower Generally operated 363 out of 365 days Two days for maintenance

Advantages Power savingCost effective Environment friendly Uninterruptive power supply

Feasibility Report Electricity condition in Pakistan Site selection Environmental impact

Electricity conditions in Pakistan Electricity production in Pakistan Power shortage of 5300 MW deficit estimated by 2011 Current tarrifs of wind energy in Pakistan by Renewable Resources (Pvt) Ltd

Reasons for windmill installation Rising prices of oil and gas across the globePakistan is suffering from electricity deficitCheap source of renewable energyNo maintenance costNo hazardous waste

Site Selection Wind speed Land study

Wind Speed Studies conducted by the Government of Pakistan (GOP) through Pakistan Metrological Department (MET Office) and Alternative Energy Development Board (AEDB) The annual mean wind speed is estimated to be 6.86m/s at 50 meter above ground level. The annual power density of area is W/m2, which bring the site into good category of power potential, which means this area is suitable for large economically viable wind farm.

Major wind resource areas – Southeastern Pakistan especially Hyderabad to Gharo region in southern Indus Valley Coastal areas south of Karachi Hills and ridges between Karachi and Hyderabad – Northern Indus Valley especially Hills and ridges in northern Punjab Ridges and wind corridors near Mardan and Islamabad – Southwestern Pakistan especially Near Nokkundi and hills and ridges in the Chagai area Makran area hills and ridges – Central Pakistan especially Wind corridors and ridges near Quetta Hills near Gendari – Elevated mountain summits and ridge crests especially in northern Pakistan

Site Selection for Project Gharo Southeastern Pakistan Current tarrifs of wind energy in Pakistan by Renewable Resources (Pvt) Ltd

Site Description The Gharo Hyderabad wind corridor is identified by the AEDB as a resource of high wind regimes with a potential of wind power generation of more than 40,000 MW.

Location South-eastern part of Pakistan between Hyderabad and Karachi In western and northern directions, a sparsely populated semi-desert area with rare vegetation can be found While in eastern and southern directions the Indus delta region provides agricultural land with consequently higher population density.

Location of the wind farm site

Land study Partly rocky Less vegetation Two hills about 60 m high 1283 acres about 5.2 km sq Installation of 50 MW wind farm Settlements Nooriabad and Jhimpir

Economic impact Cost analysis Generating cost 1. Capital investment 75% 2. Maintenance cost 25% It’s a capital intensive project requiring heavy investment in the initial stages Turbine price is the largest single investment approximately 60%-80%

Economic impact

The total investment for the proposed project is Rs: 850 million and pay back period 7-8 years. The capital cost of a typical wind power project ranges Rs 4 to5 crore per MW. Pakistan Meteorological Department WIND ENERGY PROJECT A Project funded by Ministry of Science & Technology
