CHALLENGES OF ANGOLA POWER SYSTEM

FOR THE PERIOD 2009-2016

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

2016 3050 22,00 4760

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.

Main Projects in the field of Generation:

a) Conclusion of the rehabilitation project of Cambambe 1 power house and increase theheight of the dam;

b) Construction of Cambambe II power house

c) Construction of Lauca and Caculo Cabaça Hydro power stations

d) Construction of the first Combined Cycle Thermal power station of Soyo;

e) Construction of a new Thermal power station in Namibe (backup and additional

power for the rehabilitation of the Matala Hydro power);

f) Construction of the Jamba Ya Oma and Jamba Ya Mina Hydro power stations;

g) Rehabilitation and Enlargement of Luachimo Hydro power station;

h) Construction of new the Hydro power stations of Luapasso, Chiumbe-Dala and

Chicapa II6

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

Measures aimed at encouraging the private sector participation to theEnergy sector Program

• Legal framework reform;

• Institutional framework Reform;

• Clear and stable rules for the private sector participation;

• Studies and research related to the sector



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
