The money would support the first 160 megawatts phase of the Ouarzazate plant, being developed by the Moroccan Agency for Solar Energy and a private partner, the World Bank said on Thursday.
"Ouarzazate demonstrates Morocco's commitment to low-carbon growth and could demonstrate the enormous potential of solar power in the Middle Eastand North Africa," said World Bank president Robert Zoellick in a statement.
"This solar project could advance the potential of the technology, create many new jobs across the region, assist the European Union to meet its low-carbon energy targets, and deepen economic and energy integration in the Mediterranean," he said.
Ouarzazate is only the first part of Morocco's ambitious plan of developing 2,000 megawatts in solar power generation capacity by 2020.
The first stage is a concentrated solar power design, using parabolic trough mirrors to concentrate solar energy at a receiving tube that contains fluid material to absorb and carry the heat to a generator.
In July France said it would allocate 103 million euros ($A138.17 million) to help finance the Ouarzazate solar project.
