As part of the agreement, also known as China-Pak Economic Corridor (CPEC), the Chinese companies will operate the projects as profit-making entities, reports Reuters.
China plans to invest approximately $33.8bn in various energy projects and another $11.8bn in infrastructure projects.
Under the terms of the agreement, the Chinese government and banks will provide loans to Chinese companies, including Three Gorges and China Power International Development, for investment in energy projects.
Pakistan Water and Power Minister Khawaja Asif said: "Pakistan will not be taking on any more debt through these projects."
The banks include China Development Bank and the Industrial and Commercial Bank of China.
About $15.5bn worth of coal, wind, solar and hydro energy projects are expected to be commissioned by 2017 and a 10,400MW of energy will be added to the national grid, as part of CPEC agreement, officials said.
An additional 6,120MW of energy, worth $18.2bn, will be added to the national grid by 2021.
Asif added: "In total we will add 16,000 MW of electricity through coal, wind, solar and hydel plants in the next seven years and reduce power shortage by 4,000 to 7,000 megawatts.
"This will take care of a growing demand for power by a growing economy."
