Solar energy: strengthening ENGIE’s diversified renewable energy mix

ENGIE designs, builds and operates grid-connected photovoltaic solar plants. Based on the direct conversion of sunlight into electricity, this proven technology is fast to deploy and cost-effective for large-scale renewable energy generation. ENGIE pays close attention to environmental integration, stakeholder engagement and long-term asset performance. Our solar projects also contribute to local development by sharing value within communities through taxes, local programs, dedicated offers and opportunities for local investment.

In France, the Marcoussis solar plant, inaugurated in 2021, generates the equivalent of the annual electricity consumption of more than 10,000 people. Internationally, ENGIE develops large-scale projects such as Khazna Solar PV in the United Arab Emirates. This 1.5 GW plant – the largest ever developed by ENGIE – is being delivered with Masdar under a 30-year PPA signed with Emirates Water and Electricity Company (EWEC). Scheduled for commissioning in 2028, it will supply around 160,000 households and avoid 2.4 million tonnes of CO₂ emissions per year.

ENGIE is also developing battery energy storage systems (BESS), particularly relevant in fast-growing solar markets such as India. These systems store excess electricity when production is high and feed it back into the grid when needed, enhancing flexibility and grid stability. In early 2026, ENGIE was awarded its first hybrid solar + storage project in India by the Solar Energy Corporation of India. This project, where storage is directly coupled with generation, will deliver up to six hours of renewable energy – a first in the country – while ENGIE continues to expand such solutions globally.

For businesses and local authorities, ENGIE develops on-site solar solutions by leveraging all available surfaces: rooftops, parking canopies and ground-mounted installations.

ENGIE manages the entire project lifecycle — from design and financing to construction and operation. Clients can thus produce and consume their own renewable electricity through long-term Power Purchase Agreements (PPAs) or asset leasing solutions.

Combined with storage and energy management systems, these installations cover part of electricity needs, reduce costs and strengthen long-term energy independence. ENGIE can also implement local collective self-consumption schemes, enabling nearby users to share the electricity produced.

ENGIE already supports numerous industrial and tertiary clients.

In France, we equipped Stellantis’ historic Sochaux plant with one of the country’s largest solar carport installations. In Spain and Belgium, projects delivered for Heineken and Luik Natie demonstrate ENGIE’s ability to combine on-site solar, storage and smart energy management.
