Ghana has ordered a small fleet of emergency barges with the capacity to generate up to a total of 1,000 megawatts of electricity to address a worsening power crisis, the government said on Monday. Inadequate water levels at the West African country's three hydro power facilities and the frequent breakdown of equipment at power plants has resulted in demand outstripping supply, Minister of Power Kwabena Donkor told a news conference. The barges with onboard power-generation capacity will float off the capital Accra. They were ordered from General Electric and other suppliers, and are expected to begin arriving in April so all are in place by the middle of the year. Ghana's power crisis has led to long outages for consumers, including industrial users such as mines and manufacturing firms.
