Thar desert is located in south-east Pakistan carries 175 billion tons of coal and is the biggest coalfield in Asia. In this paper mathematical framework is developed for the accurate estimation of power production from the available Thar coal capacity. Annual TWh possible energy production the period 2020 to 2040 followed by detailed analysis of capacity factor and Maximizing the share percentage of coal in total energy mix at least 40% by 2040 is presented. The findings reveal that Thar coal has the capability of producing 100,000 MW power up to the next 250 years. The energy generation for the years 2020, 2032, and 2040 is calculated 744 TWh per year, 700 TWh per year, and 665 TWh per year respectively and it produces negligible negative impacts on the environment. The long-term energy planning presented in this paper would attract foreign investment and Pakistan's energy needs would be fulfilled for sustainable development of the country.

塔尔沙漠位于巴基斯坦东南部，蕴藏着1750亿吨煤炭，是亚洲最大的煤田。本文开发了数学框架，用于根据可用的塔尔煤容量准确估计发电量。介绍了 2020 年至 2040 年期间的年 TWh 可能能源产量，随后详细分析了产能因素，并提出了到 2040 年将煤炭在总能源结构中的份额百分比最大化至少 40%。研究结果表明，塔尔煤在未来 250 年内有能力生产 100,000 兆瓦的电力。2020 年、2032 年和 2040 年的发电量分别计算为每年 744 TWh、每年 700 TWh 和每年 665 TWh，对环境产生的负面影响可以忽略不计。
