SITUATION OF THE POWER SECTOR IN ANGOLA
DIAGNOSIS
• Significant restrictions to access - it is estimated that in 2008 onlyabout 30% of the population had access to electricity;
• Strong limitations in the ability to generate power;• High inoperability of the assets (estimated at between 40% and
50% of the existing infrastructure throughout the chain value);
• High costs of power supply, the costs are estimated at $ 220 perMWh;
•
High subsidies, with an average tariff of $ 42 per MWh, about 80%of the total network costs supported by the State;
• The Insufficiency of the human resources skills,
• Structural financial deficits of the public enterprises;

PRIORITIES
• Rehabilitation of the non operating infrastrutures;
• Strengthening of the network capacity to prevent bottlenecks;
• Investing in technologies which allow quick implementation andcontrolled costs
• Interconnection of the main power systems in order to optimizethe allocation of the installed capacity and facilitate the
response to peaks;• Strengthening the rate of electrification (not just in urban
centres and areas;
• Promotion of the use of renewable energy technologies as a
preferred choice in rural areas and isolated networks 3

NOTE: The peaks of 2008 & 2009 were
recorded. Although, in these recent years the
available capacity has been greater than peak.
There were sharp restrictions of electrical
supply estimated in between 60 to 80 MW
because of the bottleneck in transmission and
distribution networks.
The peak provided for 2016 is 5 (Five) times higher than the peak recorded in2009 and represents a power equivalent to about 6 (Six) times the capacity of Cambambe Central.

In the field of Transmission: Construction of the transmission lines associated to the new power plants,
In the field of Distribution: • Expansion of Luanda distribution network ;
• Expansion of distribution networks of the capital cities and towns of the
eastern provinces which are connected to the main power grid ;
• Expansion of Cabinda distribution network
2. Promote the implementation of development of mini-hydropower stationsprogram, seeking private sector participation.
3. Ensure the implementation of the Wind Park at Baia dos Tigres (Namibe),
with the participation of the private sector
4. Implement a new tariff model in order to ensure the self-financing of the
power sector expansion

RENEWABLE ENERGY SOLUTIONS
• Development of Small hydropower program, including the realization of feasibility
studies and project executives studies of 50 hydroelectric power stations;
• Development of a solar photovoltaic systems projects which includes the installation
of 63 photovoltaic systems in 52 localities;
• Development of wind mapping for energy generation in Namibe
• In isolated networks where hydropower, solar and wind, are adopted, it is expected to
maintain the use of thermal generation source and / or energy storage systems
(reservoirs and water pumping systems, battery for solar / wind systems) to guarantythe continuity of supply.
• In rural areas , renewable energy (especially the mini-hydro, and wind and solar) may
be the most interesting alternative not only from the perspective of sustainability, but
also from an economic perspective and short time needed to ensure the supply to
the population. 8

General regulations for the participation of private entities
a) Preference should be given to the Public-Private Partnership model (PPP)
b) The form and the dimension of the participation of both the private sector and the
government should be defined; for instance, regarding the use of State treasure
resources (ROT) or loan from national or overseas sources;
c) Adoption of integrated planning during the project works execution, financing andoperation (BOT or Project financing);
d) Selection of enterprises or private companies consortium, according to their proven
financing capacity related to the dimension of the investment to be realized;
e) Preference should be given to the participation of private enterprises to the
investment risks, with the turn over associated to the financial outcome of the sale of
electricity to the final consumer.
f) High importance should be given to the training of local work force through
appropriate methods of transfer of technology and know-how. 11
