PV power plant for CPL SOUANI in Tunisia

Cost-efficient and reliable solar power for self-consumption in commerce and industry

In 2020, KRAFTWERK and its Tunisian partner SOLAR ENERGY SYSTEMS (SES) formed a strategic partnership. By pooling their international as well as local know-how and experience, they jointly develop and implement photovoltaic (PV) power plants for self-consumption in the industrial and commercial sector in Tunisia. The partnership aims at cost-efficient and reliable PV systems customized to the electricity needs of the consumers and to the Tunisian regulations and adhering to international quality standards.

In summer/ autumn 2021, KRAFTWERK and SES designed and implemented their first joint project for CPL SOUANI in Lansarine, Tébourba, 30 km from the capital Tunis. CPL SOUANI is a family-owned and -managed cheese dairy renowned for its high-quality European cheese variety for the Tunisian market.

The 85 kWp PV system is mounted on the roof of CPL SOUANI’s production facility and is connected to the medium-voltage grid. It covers up to 70% of CPL SOUANI’s electricity needs during sunshine hours and reduces the grid-power consumption by around 35% per year. Solar energy surpluses are injected to the grid and are remunerated. The installation was financed by a mix of CPL SOUANI’s own capital and a loan with favorable conditions from the bank UIB under the program SUNREF Tunisie and received an investment subsidy from SUNREF and from ANME.

The customized PV power plant and the smart financing structure allow for a profitable investment with a short payback period. In addition, the PV system reduces CPL SOUANI’s CO2 emissions by around 70 tons per year and by around 1700 tons over its lifetime.

Real-time PV plant performance

On December 9, 2021, the solar power system was inaugurated at an exclusive event at CPL SOUANI attended by around 30 guests from Tunisia and Germany representing the project partners, financing institutions as well as authorities and the private sector. In the event, representatives from the German Embassy in Tunis, the Tunisian Ministry of Industry, Mines, and Energy, ANME, SUNREF Tunisie and UIB emphasized the lighthouse character of the successful Tunisian-German model project.

Mr. Walid Gahbiche, Managing Director of CPL SOUANI, stated: “Two of our core values at CPL SOUANI are environmental and financial sustainability. That’s why we are aiming to become more independent from fossil energy and to substantially decrease our carbon footprint. The PV power plant concept presented by KRAFTWERK and SES has encouraged us to take a huge step forward and to invest in our own solar power generation. It is a great pleasure for us to deal with a German company and we are very happy with the result.”

Dr. Roman Brinzanik, Director New Markets at KRAFTWERK, pointed out: “This model project and the cooperation demonstrate how solar PV power plants can be successfully financed and implemented in the commercial and industrial sector in Tunisia. It is a win-win situation. With its own investment, CPL SOUANI saves energy costs and at the same time protects the environment by reducing CO2 emissions. Through such solar power plants for self-consumption, the private sector can substantially help accelerating Tunisia’s ambitious transition towards affordable and clean energy.”

The PV power plant for CPL SOUANI was selected as a showcase installation. This project is part of the worldwide dena Renewable Energy Solutions Programme coordinated by the Deutsche Energie-Agentur (dena) – the German Energy Agency – and supported by the German Federal Ministry for Economic Affairs and Energy (BMWi) within the German Energy Solutions Initiative. The dena RES Programme, known for its high selection criteria and standards, has previously worked with KRAFTWERK on another lighthouse project in Chile.
