Pakistan produced 1,135 megawatts of renewable energy for the month of October 2016. Pakistan expects to produce 3,000 megawatts of renewable energy by the beginning of 2019.In June 2008 the nuclear commercial complex was expanded with the ground work of installing and operationalising the Chashma-III and Chashma–IV reactors at Chashma, Punjab Province, each with 325–340 MWe and costing ₨ 129 billion; from which the ₨ 80 billion came from international sources, principally China. A further agreement for China's help with the project was signed in October 2008, and given prominence as a counter to the US–India agreement that shortly preceded it. The cost quoted then was US$1.7 billion, with a foreign loan component of US$1.07 billion. In 2013 Pakistan established a second commercial nuclear complex in Karachi with plans of additional reactors, similar to the one in Chashma. The electrical energy is generated by various energy corporations and evenly distributed by the National Electric Power Regulatory Authority (NEPRA) among the four provinces. However, the Karachi-based K-Electric and the Water and Power Development Authority (WAPDA) generates much of the electrical energy used in Pakistan in addition to gathering revenue nationwide. In 2014, Pakistan had an installed electricity generation capacity of ~22,797.
