The Gran-olo-Sula Project - ESHA

The Gran-olo sula Project:
MHP implementation in the Hinterland of Surinam
by
Dr. Eduard DOUJAK
and
Dr. Sieuwnath NAIPAL
08.3.1 Hidroenergia 2008 – Bled/Slovenia

Design, construct and implement locally a
Micro Hydropower Plant for the conditions of
Suriname aiming to provide electricity on a
sustainable way
08.3.2 Main Objective

08.3.3 General overview and background
N-E Trade winds Dec - Jan
S-E Trade winds April – August
Annual average rainfall

• District Sipaliwini
• Lower Tapanahony river
• Study area encompasses about 13 villages
with Drietabbetje as main of the local
government.
• The villages are found within a radius of
about 7-8 km from the Energy source (MHP
site).
08.3.4 Location of the project

08.3.5 One way to access the Hinterland
Site at the
Tapanahony river

• Two airstrips: (1) at Puketi, and (2) at
Drietabbetje. Flight duration Paramaribo-
Dritabbetje 50-60 min.
• A railway at Futupasie for facilitating
transport of goods.
• Duration water transport from Albina to
Dritabbetje ±2days
• Some of the villages are not foreseen with
electricity
• Telephone connection with Paramaribo
08.3.6 Infrastructure

08.3.7 Aerial view
09 feb 2008

• Some of the villages are for seen with
electricity (by diesel generators)
• Electricity generation only between
18:00 – 11:00 our.
• Is being subsidized by the central
Government (Paramaribo, about 10
barrel diesel per “village”).
08.3.8 Electricity provisions

• Health care
• Lightning during the nocturnal hours
• Schools and other public places
• Private persons for conserving of food
• Tourism (industries)
• Sawmill units
• In the near future Telecom and Television
08.3.9 Sectors in need of electricity

• Serious fluctuations of water levels observed. In
general 4-6m, with an average fluctuation of
about 4m.
• Minimum head 2m.
• Maximum head 6m
• Design head 3m
• Estimated minimum discharge at the
surroundings of the site - 15 m 3 /s
• Estimated maximum discharge >50 m 3 /s
