Dont laugh: the Nigerian govt is at the early stages of planning its first nuclear power plant - click here for more. I'm not sure if the international community would welcome this development. How well could the site be protected from militants, given the inability to find peace in the Delta? With Nigeria's track record on maintenance, would this technology really be welcome? How would the eventual deccomissioning be planned?
Rather than go with the UK and think nuclear, a more enlightened approach would consider the latest advances in alternative energy, such as heliostatic systems as shown in the image on the left. A bank of mirrors focuses the suns rays onto a steam turbine, generating cheap low-carbon electricity. The entire city of Seville is soon to be powered by one such system. With the availability of land in Northern Nigeria, and the vastly cheaper costs involved compared to nuclear, as well as the reduced security risk, this seems like a more sensible option to explore. Each station is capable of producing (at current technology levels), 10 to 15 Mw of power. Each city would in time have its own heliostat station, decentralising power via a smart grid system, reducing transmission issues in the process.
