ZE ENERGY raises €40m in a new funding round

November 26, 2021

Paris, France, 26 November 2021Less than two years after its creation and following the completion of a first seed round of funding worth €5.2M, ZE ENERGY, a French independent renewable energy producer operating hybrid solar power plants (photovoltaic and storage), announces the completion of a €40M Series B round of funding that will help bring the company to new heights.

Backed by its initial investors, DEMETER, High-Tech Gründerfonds (HTGF), EverWatt and Ze Way Invest, the company can now count on the support of Marguerite, a European investment fund focused on infrastructure and renewable energy investments. The SOREGIES Group, which had partnered with ZE ENERGY in 2020 to commission the first solar farm featuring a storage system in France, also acquired a stake in the company’s capital.

A host of new development prospects in france and in europe

Equipped with a battery that stores the solar energy generated during the day, ZE ENERGY’s new generation power plants boast all the advantages of solar power in terms of production costs, integration to the environment and power grid, as well as generation of zero CO2 emission energy.

This business model has proved both relevant and attractive, as shown by the highly promising start of the company, which despite the health crisis has initiated and completed numerous projects, while beginning its expansion abroad, with a first site in Germany.

This fresh infusion of capital will support ZE ENERGY’s growth in France and Europe alike. The company’s roadmap for 2022 includes:

  • A doubling of staff, to reach about 40 employees,
  • A new presence in Italy and Spain,
  • New purchases of land to build solar plants featuring storage capabilities that will be operated by the company,
  • The increasing development of direct sales, through Corporate Power Purchase Agreements (CPPAs). These long-term contracts between a photovoltaic energy producer and an energy consumer combine two key advantages, protecting consumers against the volatility of energy prices while enabling them to use green energy produced in France.

Today, ZE ENERGY has a project portfolio totaling over 300 MW in photovoltaic solar power and over 120 MW in battery storage. By 2025, the company aims at reaching, thanks to its deployment in five countries, solar plants amounting to more than 800 MW in total PV capacity, and over 300 MW in running battery power, for a turnover of about €60M.

We are thrilled by this second round of financing that will give us additional resources to speed up our development in the competitive renewable energy market in France and abroad. This operation reflects the strength of our business model and of our positioning as a multi-country independent producer aiming at flexible production of solar energy marketed in a short circuit to companies and communities. By 2050, electricity consumption is expected to increase by more than 30%. The government has decided to step up a gear in regards to renewables in order to meet this growing demand. Our hybrid power plants are a key part of this ambition. We are delighted that Marguerite and SORÉGIES join us, providing essential support to ZE ENERGY. We would also like to extend our heartfelt thanks to our first investors, who have trusted us from the beginning, and specifically to Demeter, who made a significant new investment in this round of financing.

Mathieu Lassagne, CEO, ZE ENERGY

We are delighted to assist ZE ENERGY in this decisive stage of its development. The founding team led by Mathieu Lassagne has succeeded in creating a value proposition that is highly relevant to the photovoltaic and electricity sector, meeting the need for flexibility and reliability of supply through innovative marketing contracts. We are proud to support the growth and internationalization of this company that fits perfectly Marguerite’s philosophy as a European investor promoting renewable energies.

Guillaume Rivron, Partner, Marguerite

It is with great pleasure that the SORÉGIES Group has assisted ZE ENERGY in its first successes as a business: the first storage battery on a photovoltaic farm and the signing, for the first time in France, of a PPA enhanced by a storage solution for a total of 150 GWh/year of renewable energy. These collaborations are further proof of the soundness of ZE ENERGY’s value proposition, and we are pleased to acquire an equity stake in the company, which will enable ZE ENERGY to accelerate its rolling out of innovative solutions to support the energy transition: new models for generating and marketing renewable energy, solutions and models for making the electric grid more flexible, and integrated energy offerings for communities.
