Who we are?

Our ambition is threefold: to fight against global warming, to support the agricultural transition of our farmers and to produce the least expensive energy

Our vision

TSE was born in 2016 from the observation that we consume as much energy from fuels today as in the 1970s.

The climate crisis, an increase in the need for electricity, the aging of our nuclear power plants, energy imports (€115 billion in 2022), the loss of sovereignty, constant increases in electricity bills for households and businesses... we wanted to tackle these challenges, and many others.

To do so, we innovated, we developed agrivoltaics very early on, we made the choice to involve all different sector to benefit quality, we developed sites throughout country to be as close as possible to different stakeholders’ needs...

Our strategic choices and our teams now offer a range of solutions to be developed with local actors and farmers, allowing us to act on a daily basis to lower the carbon footprint of our economy, to offer the most competitive rates in the long term for our industries and our fellow citizens and to share the newly created value directly with our communities and the agricultural world.

Each of our projects is designed to have a positive impact on the community and provide concrete assistance to farmers. In addition to developing and producing solar energy, we now consider ourselves, alongside local actors, as artisans adapting to the necessary changes.

Tomorrow, our communities, in addition to feeding our country, will produce its carbon-free energy.

Our founders

Mathieu Debonnet and Pierre-Yves Lambert, entrepreneurs committed to solar energy and the fight against global warming, together created TSE in 2016, which has become the leading company in the photovoltaic and agrivoltaics industry in France. Pierre-Yves Lambert founded Emeraude Energy in 2006, while Mathieu Debonnet built his expertise by creating Altus Energy in 2008.

Driven by a passion for entrepreneurship and convinced of the crucial role of photovoltaics in the future of energy in France, they created TSE to respond to a simple economic problem: to produce the least expensive carbon-free French energy while supporting the agricultural transition of French communities.

Their complementary backgrounds merged to give rise to an independent French company, with French capital, distributed as close as possible to stakeholders' needs (15 offices), resolutely committed to the French energy transition, combining innovation, technical expertise and environmental commitment.

Under the joint management of Mathieu and Pierre-Yves, TSE has established itself as the French expert in photovoltaics, and the reference in agrivoltaics.

Our purpose

TSE's commitments are clear: fighting global warming, acting locally in the energy and agricultural transitions, developing qualitative solar solutions that benefit farmers and, more generally, rural communities, and offering the least expensive production rate.

We will support you throughout the lifespan of your project through our pioneering choice of agrivoltaics, the development but also the operation of our power plants, and our presence throughout the country, as close as possible to your needs.

Trough co-construction, real value sharing, and protection of crops against climatic hazards, we are convinced that the inevitable energy transition must benefit the greatest number of people.

TSE at the heart of our communities

TSE is committed to actively working with local communities at the heart of our country to develop sustainable energy solutions which benefit all parties.

In a constantly changing energy and agricultural landscape, TSE is committed to designing each of its projects in response to the specific needs of the regions involved. We are fully aware that the success of our initiatives depends on their harmonious integration into local communities, which is why we attach the utmost importance to their active involvement.
