The job cuts, which TAQA expects to save more than $20 million in 2014, come just a month after its sale of a $240-million stake in a Dutch gas pipeline.
"We will continue to reshape the portfolio and manage our exposure to ensure we have the right balance of international assets and quality of earnings," Chief Executive Officer Carl Sheldon said.
"We will concentrate on those businesses where we have a distinctive advantage and that deliver most effectively on the vision of Abu Dhabi and the United Arab Emirates," Sheldon added.
Sheldon said staff numbers in Abu Dhabi had swollen during TAQA's international expansion but it wants to increase efficiency by relying more on local teams it has built in 10 other countries.
Many international energy companies are trying to rein in spending and sell non-core assets in the face of a weaker outlook for oil prices.
Having already concluded the sale of the Dutch gas pipeline stake, it now hopes to raise $181 million through the sale of part of its Moroccan power business.
