I missed this one when the Aksa/GDC term sheet was announced, but this website mentions that Aksa had signed an MoU with the government already to build the power plant:
"Earlier this month, Cameroon Minister of Water Resources and Energy, on behalf of the government of the Republic of Cameroon, signed a Memorandum of Understanding (MoU) with Aksa Energy to develop the power plant project"
"...Victoria Oil & Gas (VOG) finally has some good news.
My sources say the AIM-listed firm, which extracts gas from Cameroon, has signed a deal to supply gas to Aksa Energy, Turkey's biggest power company.
VOG will supply up to 25 million cubic feet per day of gas to Aksa's planned power station in Cameroon. The deal is still subject to government sign-off and won't start until next year. But it will be a big step towards profitability."
