Demand side management (DSM).


DSM Definition

• Manipulation of the load shape

– Lower it

– Change its shape

• Through

– Codes and standards

– Change behavior

– Change technologies

– Pricing


Libyan-Egyptian Interconnection:

The feasibility study of the Libyan-Egyptian Interconnection concluded that exporting 500MW to Egypt is possible.

Libyan-Tunisian Interconnection:

The feasibility study of the Libyan-Tunisian Interconnection suggested the possibility of exchanging 500MW in both directions over 400kV voltage level.

Libyan-Algerian Interconnection:

The technical study of the Libyan-Algerian Interconnection has been implemented exchange 400 MW between the two countries

Cross-Border power exchange


GECOL future vision

Increase the exchange capacity between Libya and neabering country. Libyan-Italian Interconnection: The preliminary findings of the feasibility study of the Libyan-Italian Interconnection over DC through submarine cable suggested that exporting 1000MW to Italy is possible. Libyan-Greek Interconnection: Discussions between Libya and Greece are underway, with emphasis on the importance of such interconnection aiming at exporting 3000MW to Greece.


Interconnection with Neighboring Countries


Using smart grid and meters to manage and operate the network.

Power quality issues:-

THD and voltage swell and sage specially in the distribution network.

Challenges facing at GECOL


Minor and major inspection for power plants which force us to stop them, as a results overdue maintenance needed. This situation causes a power shortage.

Building our capacity specially in following:-

• generation transmission project management.

• Renewable energy integration in the planning stage.

• Asset management and online conditional monitoring.

• Energy efficiency for both the end use equipments and network operation.

Damage in Libyan network during the revolution
