The Democratic Republic of Sao Tome and Principe is comprised of two islands and several islets of volcanic origin. They are located slightest north of the Equator line 200 miles west of Gabon, right in the middle of the Gulf of Guinea.
The two main islands cover a total surface of 980 km2.
The Island of Principe spreads over circa 130 km2, ranging from about 15 km east west to 20 km north south.
Climate is typically tropical and features an extremely exuberant vegetation together with highly diversified landscape.
Morphologically it is distinctively characterized by prominent peaks in unusual shapes that may reach heights in excess of 2,000 meters.
For such a small size, the capital in terms of natural resources of worldwide interested is quite impressive.
A vast number of water creeks and falls more than 30 m high.

2.1 Economical

Economy shows signs of macro economical recovery Sao Tome and Principe subject to insular isolation.
Administration and people unable to stop increase of external debt.
Malaria is major social factor impairing economical activity. Agriculture stills the dominant sector of production activity.
Much of the work force have defected the agricultural communities.


3.1 Migration patterns

“clash” with globalization process, New job opportunities, Desertification of the islands
Arriving immigrants, Contributions from the “returnees”, Technical training, Home coming conditions, Free Zone development.

3.2 Human Resources

ZFP to be implemented along 4 phases, Strains at social – economical level, Moving power for development, Specific work opportunities, Looking forward to development, Valuing local human resources, Increasingly organized communities, Incentives to high level training, Rehabilitation of agricultural communities, Moves towards aggregated fishing, Cultural promotion and Exports of land products.

3.3 Natural resources

Principle A – Environment
Protecting the endemic species, Environment Monitoring Centre, Support protection to the Turtles, Praise the natural environment.
Principle B – Technical
 Help improving access roads, Transportation of goods between the capital city and the Free Zone, Guarantee of road network within the Free Zone, Natural Resources as decisive element, Beaches as “windows” on to the Atlantic, Shore lines of green protection, Enhancing residential settlements, Utilize by keeping up and cleaning, Ready for immediate settlement, Capacity of each Operative Unit, Rehabilitate Sao Joaquim.

Infrastructures whatever the nature virtually non existent:
Potable water
Electric power
Sewage network
The utilities are essential
Global concept
State of the art technologies
Environmental posture
Sustainable results
Phased intervention


1 – Power generation
Diversified programme – quick and efficient response
Diesel power plant
Two diesel generators – capacity 800 to 1000 kVA each
Hydroelectric plant
Creek water levies – ducting to turbine units generated power around 1000 kVA
Biomass fuelled plant – 10 Mw electrical and 5 Mw thermal for the very near future target is to reduce the oil fuel consumption to the very minimum a further 2x2000 kVA diesel units for UOP1 to be later used as emergency units for the whole distribution network

2 – Power distribution network
Medium voltage (15 kV, 50 Hz) aerial


Telecommunications digital system – central switch board satellite connection – optic fibre buried network modules for diffusion/reception – global wireless


Out of W.T.S. – Water Treatment Station collected from min – hydro plant levies
W.S.R. - Water Supply Reservoir
Water pumping units feeding via interconnecting manifolds road links between the various UOP’s within the PFZ for UOP1 water collection from drilled wells WTS for UOP1 will serve dual purpose of water treatment and reservoir doubling as WSS
Domestic water heating via solar panels


Considering that we are dealing with an almost virgin forest environment to be preserved, the disposal of effluents from the port area and residential complexes is the most critical issue.
As opposed to the other networks described previously, the sewage and effluent collection and treatment shall have to be tackled in a decentralized mode, in line with the principles established for spreading the residential nucleus within each UOP.
We expect to reach a highly efficient treatment performance at reduced costs, since for every residential nucleus one compact treatment plant shall be provided simultaneously and within the perimeter.
Drawing of the effluents is by gravity, avoiding the need for pumps, and each treatment plant shell be designed with ample capacity for the size of the UOP to be served, in terms of population equivalent.


As for the effluents, human activity generates the production of solid residues of rather heterogeneous qualitative composition (organic products, plastics, paper/carton, iron and aluminium, tumbler, thin powders, etc) which require the proper technical handling on a continuous basis in order to avoid creating a public heath problem.
They have to be collected treated and disposed of.
For the implementation of UOP1 we have not foreseen recovery and up grading of any particular type of residue. During implementation of UOP2, 3 and 4 some residues shall be recycled for power production as biomass fuels.
At a later stage, these services will probably be allocated to be established, for example by indexing service price to water and energy costs.

The Gulf of Guinea is a busy area not only for the many oil drilling platforms and associated support vessels but also for international fishing flutes involved in catching tuna, marlin, grouper and shell fish or cephalopods.

Piracy near the coast and poor post facilities along the west coast make life difficult and thus create a hostile environment.

The same applies to small leisure craft and big yacht that are constantly cursing the gulf in amazingly large numbers.
The island of Fernando Po offers at Malabo virtually the only safe port for small ships cursing in the Gulf.
Bring able to offer an alternative safe port on the island of Principe is likely to generate a significant income for services rendered.
Namely, a more 2% of the yachts reported annually in the area would represent more than 7,500 calls per year.
Also to be secured:
Spot contracts for supply of water, consumables and victual ling to the oil platforms.
Cooperation agreements with for Eastern, European, and African fishing groups, representing at least 50 vessels ready to operate out of Principe’s logistic platform.
Oil drilling within Nigeria and Sao Tome and Principe, namely the first 20 platforms to be positioned in the area, wile no doubt guarantee the sustainability of the Free Zone project.
Taking into account the small size of the archipelago and the fact that Island of Principe is less than 90 miles from Sao Tome the resulting economic and social impacts are easy to anticipate for both islands.
For the Island of Principe side effects enhanced by the Free Zone shall be:
To capitalize on its momentum for the improvement of living and social standards on the east coast of the island.
To stern sustained development based on bipolarization at both economical and administrative levels, between the Free Zone and the capital city of the Autonomous Region, Santo Antonio.
The concession area for Principe’s Free Zone spreads around the Bay Agulhas (Needles Bay)
The northern boundary is the prominent Porta da Pedra Funda (cape).
The border line than mover southeast post Ponta do Sol than Montalegre as for as Pico Papagaio (peak).
Shifting southwest down to the village of Carriote then east-west back to the sea front at Pico Vira.
Within this perimeter, phase One of the implementation of the Free Zone will only take an area around 500 hectares.
