Morocco is inviting investors to submit pre-qualification bids for the first phase of its $9bn solar power project.

The bids invited are for the development of one or more thermo-solar units with a capacity of at least 125MW at the planned complex near the southern town of Ouarzazate, according to Reuters.

The Moroccan Agency for Solar Energy (MASEN), which has invited submissions will also launch more bids for the Ourzazate solar complex before the end of 2012, which will include constructing at least one photovoltaic solar power station.

Once complete, the solar complex will have a capacity of 500MW to power about 90,000 homes.

The complex is part of the country’s solar plan to build five power stations, accounting for 38% of Morocco’s installed power generation, by 2020.
