• Libya has invested heavily in its electricity infrastructure over the pastdecades.

• Although these investments have been directly funded by the Libyangovernment through its development budget, GECOL, the GeneralElectricity Company of Libya and its sole national power utility, has beenthe key player planning and orchestrating these investments.

• The combination of an oil rich nation with a policy of universalelectrification and a power utility with stringent criteria on the expansionplanning of its system, the result has been a robust power transmissionnetwork and ambitious undertaking of generation plant constructionprojects.

Libyan generation sector today is fully managed by GECOL, who

produces electricity through 15 thermal power plants

Overall electricity generation has remained mostly stable

since 2012, ranging between 36 and 38 TWh

• Current power generation fuel mix is mostly basedupon natural gas (~80%)

• Power generation from oil (marine oil and diesel) areexpected to phase out due to its high cost ofproduction and import

• Certainty on upstream investment and improvedphysical infrastructure are crucial to enabling gasrole in national power generation mix

• RE must be in Energiy Mix.

• Coming up with the National Energy Efficiency Action Plan(NEEAP)

• Propose the necessary laws, regulations, incentives and getit approved by the goverment

• Increase people's awareness and public acceptance of theimportance of energy conservation

• Benefit from the experiences of other countries in the fieldof energy efficiency

Reaol has been given the job of carrying out the work ofEnergy Efficiency to the stage of implementation:

• The built environment accounts for over 40%of delivered energy consumption

• The majority of energy consumed is for spaceand water heating, not electricity in mostbuildings

• The domestic sector in the Libya accounts foralmost 39% of final energy consumption

• The energy efficiency of the bulk of thehousing stock is poor

• There is significant scope for energy efficiencyimprovements with savings in space heatingof up to 90% achievable

Case Study

➢Motivation and Defining the Building

• The building is a typicalresidential building for a familylocated in Abonjeam Village, aresidential complex located inthe Central Region in Libya.

• The building is made of onestory building. The set pointtemperature is defined for thisanalysis in 24°C. The buildinghas a total volume of 594 m3

and a treated floor area of 198m2 per house.

• Improve the energy performance ofbuildings and raise the level ofthermal satisfaction.

• Reduce energy consumption in thebuilding sector.

Case Study

➢ our studies have shown that proper wall insulation alone can save up to 60% of theenergy used in MENA (Middle East and North Africa) region, especially in the residentialsector

➢ The potential for energy efficiency in buildings is very large both in new and in existingbuildings. Over time the energy efficiency in buildings can be reduced by more than 60 %alone with measures, which are feasible already today.
