The Glasgow-based temporary power company, Aggreko, has won a £100m contract in Bangladesh.
Aggreko will supply power to the Bangladesh Power Development Board (BPDB) over a three-year period.
Bangladesh has recently been affected by power shortages caused by increased industrial and domestic demand.
The company said the power was due to start being delivered in a few months time and would have a "noticeable impact" in the country,
Rupert Soames, chief executive of Aggreko, said: "Although the government has embarked on an ambitious programme to increase the capacity of the national grid, power demand is now exceeding supply, with the result that widespread power cuts are inhibiting economic development.
"Ensuring that industrial, agricultural and domestic users have a reliable power supply is vital to any economy, which is why Aggreko's fast-track power provision is an excellent solution for BPDP."
Aggreko employs more than 3,500 people worldwide, including about 200 at its Glasgow headquarters.
It has provided power for some of the world's major events, including the Bejing Olympics
In the latest stock market reshuffle, Aggreko joined the FTSE 100.
