THREE barges carrying a floating power station arrived in the Nigerian capital Lagos this week, under a deal reached earlier this year to boost chronic power supplies in the city. United States group Enron in September signed a deal with the Lagos State government to supply a 90 megawatt floating power station to be moored in the waters of the Lagos lagoon and wired into the city grid. The second phase of the deal is the building of a 540 megawatt power station on shore, as a more permanent solution to the unending power supply problems in the city. Nigeria’s ailing state-run power company Nepa is currently incapable to generating enough power for the country and the government has pledged to bring in a series of independent power producers to boost supplies.
