Today, the world’s renewable energy resource is increasing rapidly. With its 2,378 GW (including on-shore and off-shore) global installed renewable energy capacity, it contributes to one-third of all energy resources, such as fossil and nuclear energy. Hydropower, Wind, Solar, Bioenergy, GEE and Marine Energy form part of renewable energy resources. The largest part is played by hydropower and wind power in renewable energy projects.
In more than ninety countries, global wind power capacity is approximately 600 GW. China has appeared in recent years as the largest wind power distributor with an installed capacity of 214 GW (approximately 36 percent share for global wind turbines).
With a nominal 1.048 MW (megawatts) installed wind energy capacity and less than a 1 percent exploitable capacity, Pakistan rank 33rd among wind power countries. It is apparent that the government seriously plans to utilize wind potential commercially optimally and quickly to overcome the challenges of climate change.
In 1997-98, the United Nations Development Program (UNDP) conducted a full study for marketing wind energy potentials in the region, encouraging large-scale use of wind power. Finished in April 2001, the study revealed the enormous economic and sustainable development capability of the Sindh coastal belt.
In 2007, Pakistan’s Wind Atlas covering wind resources maps with wind speed and wind intensity capacity was drawn up and a commercially utilizable potential of 132 GW wind energy was established by the United States Agency for International Development (USAID) and the National Renewable Energy Laboratory (Department of Energy). The nation atlas is now part of the Global Wind Atlas, designed by the Technical University of Denmark and the World Bank Group, and has now been verified in the following years.
Nevertheless, Sindh is likely to develop about 50,000 MW of wind energy on the Gharo-Keti Bandar wind corridor, according to detailed research. These devices are known to be technologically and economically feasible for generating power.
The government initially planned to add 700 MW of wind to the national grid by 2010. In 2005, a further 15 prospective investors were allocated 23,645 ha of land in Sindh (Thatta) and, subsequently, a further 10,330 acres were allocated to another seven businessmen to build the Build-Own-BOO ventures.
In the Jhampir wind corridor, there are 20 wind farms. The wind farms have therefore installed a total capacity of 1,031 MW.
In the Gharo wind corridor, five wind turbine projects are operational with a cumulative capacity of around 250MW.
