The demand for energy has increased in tremendous proportions in the last few decades in Pakistan; the same is expected to increase further in the coming years. The primary sources of energy available in Pakistan are oil, natural gas, hydro and nuclear Power. Pakistan has around 1100 kilometers (km) coastal line for the wind energy potential, but in this manuscript, we have chosen one of the most suitable wind corridors of the southern part of the country. I also tried to prove theoretically that this wind zone is more favorable for country consumer demand. Moreover, future perspective.
Wind energy is quiet and does not present any significant hazard to birds or other wildlife. When large arrays of wind turbines are installed on farmland, only about 2% of the land area is required for the wind turbines. The rest is available for farming, livestock, and other uses. Like landowners often receive payment for the use of their land, which enhances their income and increases the value of the land. Wind energy is an ideal renewable energy because: it doesn’t require fuel and it doesn’t create greenhouse gasses it doesn’t produce toxic or radioactive waste. it is a pollution-free, infinitely sustainable form of energy It is quiet and does not present any significant hazard to birds or other wildlife. When large arrays of wind turbines are installed on farmland, only about 2% of the land area is required for the wind turbines. The rest is available for farming, livestock, and other uses. Like landowners often receive payment for the use of their land, which enhances their income and increases the value of the land. Meteorological Department (PMD), indicates that a potential exists for harvesting wind energy using currently available technologies. GE Renewable Energy is one of the world’s leading wind turbine suppliers. Our current product portfolio includes turbines with rated capacities from 1.7 MW to 3.2 MW. Additionally, we offer support services that cover everything from development assistance to operations and maintenance. Wind power is a form of renewable energy in Pakistan which makes up less than 0.1% of the total electricity production in the country. This Plant was developed in Jhimpir, Sindh by Zorlu Energy Pakistan. The total cost of project is $136 million. Completed in 2002, it has a total capacity of 50 MW. This wind Corridor has a 50000 megawatt potential with average wind speeds over 7 meter per second. Jhimpir is part of the so-called “Gharo-Jhimpir wind corridor” in Sindh province, a 180 km (110 mile) stretch of coastal land that the Pakistan Meteorological Department says has the potential to produce 11,000 MW of electricity through wind power. Ownership of wind turbine generators by individuals and the community allows people to participate directly in the preservation of our environment. Each megawatt-hour of electricity that is generated by wind energy helps to reduce 0.8 to 0.9 tones of greenhouse gas emissions that are produced by coal or diesel fuel generation each year.
The facility is the first wind farm in Pakistan to be awarded feed in tariff (FIT) by the National Electric Power Regulatory Authority (NEPRA). More advanced software tools for sculpting, drawing, development, analysis, testing and justification of the abilities and modularity of a wind energy system integrated with power-grid and internet. It is of further significance as it is the first wind farm in the country to be funded through the Overseas Private Investment Corporation (OPIC), the U.S. Government’s development finance institution, which mobilizes private capital to help solve critical development challenges. As a long term partner dedicated to the country’s growth, GE played an instrumental role in helping Sapphire achieve financial closure with OPIC. The corridor is home to Pakistan’s earliest wind project, which began in 2009 with just a few turbines and was upgraded to an installed capacity of 56 MW by 2012. Generally wind farm located in area with good winds and having a typical value of capacity factor i.e. 25% at least are economically viable. A typical life of wind turbine is 20 to 25 years. Maintenance is required at 6 months interval. The new wind farm, which opened last month, has been developed by Sachal Energy Development, with financing from the Industrial and Commercial Bank of China.
Pakistan and China have signed around $57 billion of energy and infrastructure projects under the China-Pakistan Economic Corridor (CPEC). Most of this investment is going toward coal-fired power plants, fueled both by imported coal and by coal mines in Pakistan’s Thar Desert. The CPEC projects aim to boost energy production in Pakistan to reduce shortages that lead to regular power outages.
Most important future development of the research study must consist a prerequisite of an effective strategy in order to evaluate the accuracy of wind energy generation systems. Recently conducted survey of Wind Power Potential along coastal areas of the country by Pakistan Meteorological Department (PMD), indicates that a potential exists for harvesting wind energy using currently available technologies, especially along Sindh coast. Further, it will produce employment openings for local public and indigenous trade for the industrial side for manufacturing point of view. A potential home based wind turbine model projects should be researched in order to implement in suitable wind zones in rural areas where up to now there is no power. However, proper utilization of wind potential only exists within the Sindh province for power generation, may fulfill the mandate of electricity crises in the country. we can consider our selected wind corridor for proper utilization in order to fit larger wind power plant, and it is a collective work out for installing the wind mill unit in wind zones. Although, the state of Pakistan always shows a deficit in the conventional resources, but no progress was also being made in the renewable resources such as the wind and solar energy. Therefore, it is better to utilize these natural assets in order to fulfill the electricity supply the country. Pakistan’s big business houses are diversifying their investments into the renewable energy source due to the incentives being offered, including high and guaranteed rate of return in euro and dollar parity. Nepra has allowed 17% rate of return on investments in wind power projects in the upfront tariff. Other incentives include protection against political risk, availability of carbon credits, duty-free import of equipment, exemption from income, withholding and sales tax, repatriation of equity along with dividends and permission to issue corporate registered bonds. The AEDB is encouraging development of another 10 wind energy projects in the province (Sindh) having expected cumulative capacity of 1,200MW, which would be constructed by 2019-20 through competitive bidding of tariff after shifting from the current regime of upfront or cost-plus tariff,” it said.
