400 MW BUI HYDROELECTRIC POWERPROJECT

Presentation By: Fred Oware

Chief Executive Officer (BPA)



History/Background

The Bui Hydroelectric Project wasconceived long ago after a BritishGeologist Mr. Albert

Kitson, prospecting for golddiscovered the gorge in the 1920s.

Successive governments from Dr.

Nkrumah’s time till the turn of the 21stCentury had made attempts inconstructing the dam.

In 2005 the Government ofGhana secured funding from theChinese Government to undertake theproject.



History/Background

The 400 MW Bui Hydropower scheme has been considered to

be the most technically and economically attractive

hydropower site in Ghana after the Akosombo and Kpong

hydro power plants.

Consequently it has been the subject of many studies

including:

J.S. Zhuk Hydroprojeckt of the USSR in 1966

Snowy Mountains Eng. Corp (SMEC) of Australia in 1976

Coyne Et Bellier of France in 1995.

Coyne Et Bellier updated its 1995 report in October 2006



• Bui Power Authority are the Employers who represent the

Government of Ghana ensuring quality control under the

EPC/Turnkey Project Agreement.

• Construction is being undertaken by Sinohydro

Corportation of China.

• Consultancy services are being provided by Coyne et

Bellier of France.

Environmental/Social Issues on the Bui HPP

Resettlement of about 1,700 people who reside within the project

area.

Permanent Land take (i.e. inundation of part of the Bui National

Park). It is estimated that about 444 km2 which is about 21% of

Bui National Park.

On the basis of the Environmental and Social Impact Assessment

(ESIA) carried out by ERM Consultants of the UK in October

2006, some of the key impacts are as follows:



Loss of fauna and flora (gallery forest) which is a rare along the

banks of the river.

Social Impacts during the construction phase (influx of migrant

workers, including health, cultural differences, potential social

tensions etc.)

Environmental/Social Issues on the Bui HPPKey Impacts:



Need for the design of seasonal compensational water releases

during the period of impounding.

Increased hunting for displaced animals by local population.Need to equip Game & Wildlife Department to create a safe

haven for the animals; and therafter, monitoring and supervision

of the Park.

Need to protect the hippopotamus population: Need to grow

Setaria and other plant species to increase fodder available for

the hippopotamus.

Environmental/Social Issues on the Bui HPP(contd.)

Key Impacts:



Key Impacts:

The expansion of the Bui National Park to make up for the

flooded area.

During the impoundment period of 2yrs there will be a loss of

inflow into the Volta Lake resulting in the loss of some 30 GWh of

electricity per annum. This will be corrected after completion of

the Dam and during operations.




Map indicating flooded area



Acquisition of land for afforestation to restore destroyed

endangered flora and fauna.

Payment of compensation for the lands and the destruction of

economic activities.

Consultation with Game and Wildlife still in progress for the

rescue of the hippopotamus in the Bui National Park.

Mitigation Measures




Mitigation Measures

Acquisition of speed boats to tour flooded area and rescue

wildlife during impoundment and also for continuous

monitoring work.

Camps to be built along Lake to be used by the Game and

Wildlife officials to stem illegal developments along the Bui

Lake.

Removal of trees located in reservoir area for safe navigation.




Resettlement of affected villages

Seven villages are to be physically resettled due to the Bui Dam

construction. Additionally the Bui Game and Wildlife camp would be

resettled. Four out of the seven villages have been resettled at the Jama

resettlement site, they are:

Agbegikuro and Lucene in the Bole District and

Brewohodi and Dam Site villages in the Tain District.

Auxiliary Projects

• Irrigation for agricultural development

• An opportunity to develop a Model City (Bui

City)

The Bui Project is designed primarily for hydropower generation,

however it has potential for:



IRRIGATION

Though the Bui project is designed primarily for hydropowergeneration it has irrigation potential of 30,000 ha for agricultural

development.

This is to be the bedrock of massive mechanized agricultural

programming which involves

food and cash crops,

animal husbandry and

fisheries to feed the factories to be located in the proposed Bui

Special Economic Zone in order to attract investments into the

area.

Areas envisaged for the irrigation project are New

Longoro, Asantekwa etc.



We are in serious discussions with reputable foreign and localinvestors who are anxious to make massive investments in the area.There is the potential for a 15,000 ha sugar cane plantation tosupport the production of edible sugar, molasses, ethanol, and otherderivatives of sugar.

We estimate creation of some 20,000 new job opportunities as aresult of the irrigation scheme.

IRRIGATION



IRRIGATION

Irrigation of over 30,000 hectres of land.



Overview of the Bui City

Bui Power Authority (BPA) has developedthe necessary programme to promote the

development of a modern and model city –

Bui City, in addition to the construction of

the 400MW Dam.

The project expectation is to

accommodate some 500,000 people in the

medium term.

This is to be complemented with some

30,000 hectares of an irrigation project to

offer sovereign lands for agro industries.



Bui City BPA has arranged funding to

pay for the compensation for

the acquired lands, provision

of infrastructure and

subsequent allotment to

commercial and industrialinvestors. The total area is

estimated to be 700km2.

The total cost of this project is estimated to be USD$ 350million

which is made up as follows:



Bui City Project Cost

Activity US $ 000

Compensation for land 100,000

Services 10,000

Roads and bridges 100,000

Water 40,000

Sewerage 22,000

Waste 32,000

Electricity 30,000

Engineering, Construction and

Administration.16,000

Grand Total 350,000



Prospects of the Bui City

The Bui City will attract investments which will create an

avenue for bridging the development disparity between the

northern sector and southern sector of Ghana. This will be

manifested in :

Job creation

Development of transportation networks

Development of the Agricultural sector

Improvement of educational, health facilities etc.

Significant contribution to GDP



Tourist attraction centers such as Amusementparks, the Hippo Sanctuary etc. which are integralparts of the Project will increase the tourism potentialin Ghana.

Benefits of the Bui City



Bui Airpark

Geographical Location of proposed BuiAirpark.

Construction of pillars - proposed Bui Airpark

The Bui Airpark which is an auxiliary project under the Bui City Project is

to facilitate the transportation to the Project location and its environs.



Challenges Communication: very few of the Chinese speak English

Black flies nuisance and high incidence of malaria

Difficult living conditions

Lack of skilled labour within the Dam Site communities



Recommendations

Fulfilment of loan conditions by both Ministries of Energy and

Finance and Economic Planning in order to meet the targets of the

Project.

Support from GOG to deal with the Black fly nuisance.

GOG to support BPA’s effort in the Irrigation and Bui City Projects to

diversify and improve the economies of the communities within both

Northern and Brong Ahafo Regions.

GOG to support BPA’s mission of ultimately producing hydropower atcompetitive and cheaper cost.
