Because of the large number of Pre-stressed Concrete Cylinder Pipes (PCCP) required for the implementation of the Great Man Made River Project two plants were constructed, one at Brega on the north coat of Libya and one in Sarir deep in the Sahara desert. These plants, which were commissioned in 1986, are capable of producing various diameters of pipe ranging from 1.6 meters to 4.0 meters.

Brega plant with two production lines and Sarir plant with three production lines have a combined capacity to produce 200 4.0 meter diameter pipes per day.

The Power Supply - The Great Man Made River (GMMR)

The Great Man-Made River Authority, has built power generation plant at Sarir site,
to supply the operation support and maintenance (OS&M) facilities and the well fields.
Additionally GMRA has made contracts to build several substations around the project, these substations are connected  to the general electrical company (GECOL) grid for system integration .

These power stations will be allocated as follows:

Sarir/Sirt, Tazerbo/Benghazi System

Electrical power is essential for the operation and control of the project. The total power demand for Phase I, of around 65 megawatts, is provided mainly from a power generation plant constructed at Sarir as part of the project. Power from this plant will be transmitted directly to Sarir well field via a 66 kv transmission line, and indirectly to the Tazerbo well field via the existing National Power Supply System, at 220 kv. The power will be transformed down to 66 kv at Tazerbo substation and transmitted to the distribution stations at Tazerbo well field via a 66 kv line constructed for this purpose. Sarir power generating plant consists of six gas turbine generating sets which can operate on diesel fuel if the need arises.

Hasouna/Jefara System

Power for wellfield and pump stations is supplied from the National Grid System operated by the General Electricity Company of Libya (GECOL) from two 220/66 kv substations, GM1 and GM2.

For the GM1 and GM2  substation's), 66 kv single circuit transmission line feed 66/33/11 kv electrical substations (ESB).

Gardabiya/Assdada System

Supplying the system by the power supply from the (GECOL) through create a transferring station 220/66 kv at Assdada, and Increasing the capacity of the existing Gardabiya substation to 66\11 kv.

GECOL (the General Electricity Company Of Libya)

is the electric utility of the Great People's Libyan Arab Jamahiriya. It is solely responsible for generation, transport and distribution of electric power in the whole country.
Since 1969 the Great First of September Revolution has given this sector it's top priority, the objective is to electrify all Libyan towns and cities, which almost hits the (100%) figure as of the year 2000, with the lowest possible operating cost and with an acceptable level of continuity and quality of electricity supply.
Future vision is focused on reinforcing the infrastructure of GECOL by utilizing modern technologies in the fields of Transmission and Distribution alongside exploring new avenues of renewable energy sources to support efforts for the global development in the Jamahiriya in all aspects of life.
