Electrical Power Systems and Renewable Energy

Tunisia’s power sector is well developed, and nearly the entire population enjoys access to the national electricity grid.  Tunisia has a current power production capacity of 5,653 megawatts (MW) installed in 25 power plants, which produced 20,086 gigawatt hours in 2021.  State power utility company STEG controls 91.7% of the country’s installed power production capacity and produces 84% of the electricity.  The remainder is produced by Tunisia’s only independent power producer (IPP) Carthage Power Company (CPC), a 471-MW combined-cycle power plant.  The CPC plant was officially handed over to STEG in May 2022 ending a 20-year power purchasing agreement between both companies.  As a result of delays in power plant construction, the power sector does not possess excess generation capacity and is susceptible to brownouts.  STEG is hard-pressed to meet peak summer electricity demand, let alone keep up with Tunisia’s annual 5% growth in power consumption. 

Approximately 97% of Tunisia’s electricity is generated from fossil fuels, mainly natural gas.  In 2021, nearly 45% of Tunisia’s natural gas needs were met through imports (mainly from Algeria).  Local gas production comes from the concessions of the country’s national exploration company, ETAP, as well as foreign companies’ concessions.  The highly anticipated Nawara gas field, which finally started production in early 2020, is expected to help reduce the overall energy deficit by 20% and gas imports by 30% once it reaches peak production.  In addition to the local gas production, Tunisia receives natural gas as a royalty on the Algerian Transmed gas pipeline crossing Tunisia to Italy.  In 2021, only 3% of Tunisia’s electricity is generated from renewables, including hydroelectric, solar, and wind energy.

While STEG continues to resist private investment in the sector, Parliament’s 2015 energy law encourages IPPs in renewable energy technologies.  The law’s implementing decrees and a Power Purchase Agreement template were published in early 2017.  

The first IPPs in renewable energy were announced in the second half of 2017, and so far, the GOT has awarded to private companies 24 solar projects of 10 MW each, two solar projects of 50 MW each, two solar projects of 100 MW each, one solar project of 200 MW, and four wind projects of 30 MW each.  Most of the projects are still at various phases of implementation.

To meet increasing demand for electricity and promote energy conservation, the GOT allows private companies and households utilizing co-generation and renewable energy technologies to produce electricity for their own consumption and sell up to 30% of excess electricity exclusively to STEG at a fixed price.  The GOT may provide grants and incentives for energy conservation and energy efficiency projects.  In July 2021, the GOT announced the elimination of the pre-authorization requirement for private self-production of electricity from renewable energies under 1 MW.  Through March 2022, the total capacity of installed renewable energies reached 472 MW.

In June 2022, the GOT announced an action program to promote green hydrogen production for the domestic and export markets as well as the creation of a legal framework to encourage foreign investment in this sector.

Leading Sub-Sectors

Renewable energies

Though hydrocarbon-based generation will continue to dominate Tunisia’s overall energy picture in the near term, the potential for growth in wind and solar power generation is significant.  The GOT is highly interested in diversifying into renewable energy technologies to help meet growing domestic electricity demand.  The renewable energy law adopted in 2015 encourages private businesses to generate and use clean energy.  In May 2019, Parliament passed a bill to improve the business climate, permitting businesses to create separate special-purpose vehicles entirely dedicated to power generation.  This policy change allows companies to produce power for their own consumption at more competitive prices. 

Through March 2022, Tunisia had about 472MW of installed renewable energy capacity of which 244 MW was wind power, 166 MW solar power, and 62 MW of hydroelectric power, representing a combined 8% of national energy production capacity.  The GOT aims to raise the usage of renewable energy resources to 35% of total power capacity by 2030. 

Green hydrogen

Tunisia’s abundant solar and wind resources, as well as its proximity to Europe (which has an increased need for new and clean energy sources), make it a very attractive location for green hydrogen production.  The already-available Transmed gas pipeline that connects Algeria to Italy through Tunisia is an important asset for investors considering exports to Europe.  The GOT is also working on establishing a new legal framework to promote the production and use of green hydrogen and its derivatives in the local market. 

Power generation

During the last five years, STEG was active in launching power projects, some of which utilize General Electric (GE) combined-cycle technology.  Two tenders for gas-fired power plants issued in 2014 were awarded in 2017 and 2018.  Tunisia is expected to continue launching tenders for gas-fired power plants over the next five years


While projects are often subject to delays, excellent commercial opportunities exist for the sale of power generation equipment to STEG-operated and IPP electricity projects.  The sector also offers opportunities for possible Build-Own-Operate (BOO) or Build-Operate-Transfer (BOT) projects.  Much of Tunisia’s electricity production comes from gas turbines.  Major players in this sector include General Electric (USA), Mitsubishi (Japan), Ansaldo (Italy), and Siemens (Germany).

In 2019, STEG launched a tender to install a pilot smart grid power distribution system of 400,000 smart meters.  The project was awarded in April 2022 to several foreign bidders including those from the United States and will be implemented starting January 2023.   

In 2022, the GOT is also expected to launch a tender for the construction of at least one 470-550 MW combined-cycle power plant in Skhira (south Tunisia) as an IPP. 

In May 2018, the Ministry of Energy and Mines published a call for private projects to build renewable power plans with a total capacity of 1,000 MW (500 MW wind and 500 MW solar).  While the wind projects are still in the prequalification phase, the GOT awarded all 500 MW in solar projects to three private developers in 2019.

The GOT plans to launch tenders for about 3.5 gigawatts of renewable energy, worth roughly $3.5 billion, by 2030, of which 2,000 MW will be announced in June 2022 for an implementation phase between 2023-2025.  One third of the projects will be for wind farms and two thirds for solar photovoltaics.

Tunisia’s national grid is connected to those of Algeria and Libya, but various other projects to expand electricity transmission and distribution networks across North Africa, as well as Tunisia’s sub-sea connection with Italy, have been delayed indefinitely
