Renewable Energy

A pioneer in the field of renewable energy, Tozzi Green Madagascar designs, develops and constructs renewable energy plants, managing all aspects of the process. From the initial feasibility study to the construction and commissioning of the plant, integrated management guarantees efficient and sustainable results.

Tozzi Green Madagascar develops renewable energy plants, managing all aspects of the process in an integrated manner, from the preliminary feasibility assessment to construction and commissioning.
The relationship that Tozzi Green Madagascar builds in the places where it operates is not limited to procedural compliance and formal relations with institutions, but involves the local communities by listening and finding practical solutions together. The company’s participatory approach, in line with its core values of sustainability, covers all project phases, from design to construction, for which local contractors are always preferred. Tozzi Green Madagascar supervises all the preliminary stages of the construction of new facilities, from the choice of the best site in terms of availability of natural resources and access infrastructures to the establishment and management of relations with the local communities concerned, and the management of the necessary authorisation and control procedures.

The proper management and maintenance of a plant guarantees its optimal operation, maximum efficiency and, consequently, the expected productivity. Tozzi Green Madagascar offers a complete O&M service for medium and large renewable energy plants, including routine and special maintenance (restoration and re-commissioning), remote monitoring and operation, and full service maintenance.

Tozzi Green Madagascar offers a wide range of services for the management of all administrative, regulatory, fiscal and environmental aspects related to the operation of renewable energy plants, the sale of the energy produced and the related incentives, ensuring high profitability of the plants, maintaining the value of the investment over time and guaranteeing compliance with the regulations in force.

Tozzi Green Madagascar’s presence in different countries on different continents means that it has to build relationships with stakeholders who speak different languages, comply with local regulations and have different interests. As part of the development of its business, the Group’s management, together with its various departments, maintains ongoing and systematic relations with the main categories of stakeholders through institutional and informal channels that are always transparent, documented and based on goodwill. Communication methods are specific to each operational context and are based on in-depth knowledge of the location and the people involved, in order to respond as effectively as possible to the needs of the different areas.

In Madagascar, interaction with national and local institutions is constant, systematic and fair in all circumstances, with the aim of finding the best solution to each problem. This can include addressing basic deficiencies such as the availability of electricity or water, the secondary function in the development of health care, basic education and infrastructure services that are often required of the company. The relationship that Tozzi Green Madagascar establishes in the places where it operates is therefore not limited to compliance with procedures and good relations with institutions, but also involves the local communities, listening to them and jointly defining practical solutions. These activities are carried out through formal meetings and cover all phases of the projects, from design to execution of the works, for which local contractors are always preferred wherever possible. In the case of new projects involving the construction of an energy production plant, stakeholders are always involved at several levels: with the public authority (central and/or local), with private individuals who transfer property rights and receive compensation or lease payments, and with local communities, with whom common needs are identified and protocols are agreed under which the company undertakes to support the provision of services to meet those needs.

Madagascar has an estimated hydroelectric power potential of 7,800 MW, according to the Economic Development Board of Madagascar (EDBM), but less than 3% of this potential has been exploited to date. In this context, Tozzi Green Madagascar is investing to bring electricity to the country and fight energy poverty.
Madagascar, with its dense hydrographic network, has considerable hydroelectric power potential in the eastern and northern regions and in the highlands. It is in these regions that Tozzi Green Madagascar is developing its renewable energy projects, helping to overcome the country’s energy deficit and improve the living conditions of its people.
Thanks to the initiatives implemented by the company, the development of hydroelectric power requires close cooperation between public and private stakeholders. In the long term, this cooperation will optimise investments, improve electricity distribution in rural areas and help reduce energy poverty.

Tozzi Green Madagascar is fully involved in the national energy transition process and supports the development of innovative hydroelectric power projects.
New technologies, such as micro-hydropower plants, offer solutions tailored to the needs of rural areas and can contribute to decentralised electrification.

Tozzi Green Madagascar, the country’s largest private investor in the renewable energy sector, currently operates three hydroelectric power plants. These are run-of-river plants with a total capacity of 47 MW and an output of 185.5 GWh/year.

The Sahanivotry hydroelectric power plant is located in the Vakinankaratra region, in the commune of Manandona. The run-of-river power plant on the Manandona River diverts a modulated flow of 9.1 m³/s into a penstock with a head of 243 metres. The plant is equipped with three Pelton turbines with a total installed capacity of 16.5 MW and an estimated annual output of 60 GWh. This infrastructure, operational since 2008, has increased national electricity production by more than 10% (source: BAD). It supplies electricity to around 160,000 inhabitants on the Antananarivo interconnected grid (RIA) via a 63-kV high-voltage line that passes through the Antsipolotra substation, located 19 km from the power plant. As part of the rural electrification programme, the plant will also meet the energy needs of the residents of Sahanivotry, providing an additional output of approximately 30 MWh/year for the benefit of the local communities.

The project has also had a significant socio-economic impact. During its construction, it created around 140 jobs, forty of which were local. Its operation will provide around twenty permanent jobs and temporary opportunities for the local population.

This run-of-river hydroelectric power project was constructed on the Voloina River, about 30 km west of the town of Maroantsetra, in the province of Toamasina, in north-eastern Madagascar. Commissioned in 2005, it diverts a flow of 3 m³/s over a head of 91.65 m and produces an estimated 5.5 GWh per year. The infrastructure of this plant is based on two horizontal Francis turbines with a total capacity of 2.5 MW each. These turbines are fed by a system that includes a 26-metre-long sedimentation basin and a 680-metre-long penstock to ensure optimum management of the hydraulic flow.

This plant plays a vital role in supplying electricity to the town of Maroantsetra, which has a population of around 10,000, demonstrating its ability to fully meet local needs. In collaboration with various stakeholders, the plant is also actively involved in two rural electrification projects aimed at extending access to electricity to remote areas of the region.

The power plant also stands out as the only hydroelectric power plant to be connected to an autonomous 30-km, 21-kV grid. This autonomous grid will provide reliable, sustainable energy to an underdeveloped region in northern Madagascar, where access to electricity remains a major challenge for local communities.

The Farahantsana hydroelectric power plant has an installed capacity of 28 MW and produces 120 GWh per year. It was commissioned in 2022 and supplies the Antananarivo interconnected grid via a 38-km high-voltage line and two substations (Tana-Sud and Farahantsana). The power plant is located on the Ikopa River in the Itasy region, in the rural commune of Ambohimasina, and is connected to the Antananarivo interconnected grid. It is equipped with four Francis turbines of 7 MW each. The Farahantsana power plant draws 66 m³ of water per second from the Ikopa River, which has a nominal head of about 42 m, and generates 135 GWh of electricity per year, enough to cover the average consumption of about 2,750,000 people, or 65% of the population of Antananarivo. Construction began in 2018 and involved Malagasy, Italian and Filipino companies. The construction of the hydroelectric power plant has created more than 750 direct local jobs and contributed to the growth of the town of Mahitsy and the commune of Ambohimasina. In 2017, more than three thousand people attended the inauguration of the Farahantsana bridge in Mahitsy, some fifty kilometres from the capital Antananarivo, which now links the communes of Ampanotokana and Ambohimasina, previously separated by the Ikopa River. This work, essential for the start of construction of the hydroelectric power plant, is the result of a public-private partnership. It is also an emblematic structure from a symbolic point of view. The link between the two villages has physically united communities that were previously separated by the river and unable to develop common policies and practices.
