In Angola, a country of 13 million people where power supply is chronically short,  the purchase of standby generators as part of public power supply is even officially sanctioned. Empressa Nacional de Electricidade (ENE) - Angola’s power supply authority - recently placed a 90MW temporary power station contract with Aggreko, the British company.
Angola’s import of diesel fired generating sets has doubled (by value) every year for the last four. In 2005 the South West African oil producer imported $21.7Million worth, and by 2008 this figure had risen to $164.3Million, drawing in 24,580 units in all sizes.
The growing middle class in Luanda, Angola’s capital city, used money they made from the country’s oil boom to purchase over 3,000 individual 7.5-75 kVA units at an estimated value of $8Million. The 75-375KVA range accounted for 2052 units worth approximately $17.3Million, and sets over 375 up to 2,000 kVA accounted for the remaining $85.2Million.
