Base-load Utility Power, Cabinda, Angola
The challenge to the customer
Following a period of conflict in
the region, the Cabindan utility network required extensive repairs
and power rationing had become a way of life for the 500,000
population. A reliable power supply was necessary to support
economic development and regional rehabilitation.
In addition, increased fuel
(diesel) costs, coupled with a readily available supply of natural
gas in Cabinda, meant the government was looking for an alternative
source to fuel the power supply in subsequent years.
Aggreko's solution
Aggreko initially supplied a 15MW /
30kV power package in Malongo to cope with existing demand of
Cabinda. As the population of Cabinda became accustomed to a
reliable power supply, the demand grew to 25MW. To stabilise the
network, the main power package was increased to 20MW at 30kV which
was supplemented by a 5MW power package at 15kV in the Town
Centre.
Rural electrification was also an
issue, and when Cabinda Town had established a reliable electricity
source the demand in outlying areas also increased. To meet this
demand, Aggreko installed eight ‘satellite power stations’ of 2MW
power packages in remote areas, from the rain forests in Northern
Cabinda to the area’s surrounding the regional airport.
The benefits to the customer
Although power at these sites was
initially supplied by diesel generators, Aggreko fulfilled its’
commitment to provide gas-fuelled generators and replace the
majority of the diesel powered equipment at the main power plant in
Malongo significantly reducing overall operating costs for the
customer.
