What Calycé does

Calycé is a French renewable energy project developer headquartered in Vitry-la-Ville, with operational offices in Reims and Brévonnes across France's Grand Est region. The company's founders, themselves multi-generational farmers, have been active in onshore wind since 2002 and in solar photovoltaic since 2009, formally establishing Calycé Développement SAS in 2011. The company develops, constructs, and operates wind farms and ground-mounted solar plants, with particular emphasis on agrivoltaic projects that co-locate active agricultural use (livestock, crops) with photovoltaic generation, and serves three principal stakeholder groups: farmers seeking land-leased diversified income, municipalities seeking recurring fiscal revenue (approximately €9,000–€16,000 per MW per year), and individual landowners hosting turbines.

Calycé's business model rests on full-lifecycle project ownership: site identification, feasibility studies using 101m measurement masts, environmental and acoustic impact assessment, stakeholder consultation (public consultations, door-to-door campaigns, project committees), permitting, construction, and operation. Revenue is generated primarily through electricity sales via power purchase agreements with utilities or wholesale market sales, supplemented by renewable energy certificates. The unique Souffle d'Espoir project channels 100% of operational profits from six turbines to three regional health charities, financed in part through the EnerFip crowdfunding platform. The company signed the AMORCE charter in May 2023, formalizing community-engagement standards, and reached 200 MW of installed wind capacity by 2020, with over 2,000 GWh of annual green electricity production powering more than 428,000 French households.

In 2025, Calycé underwent a significant structural reorganization: in July 2025, wpd concluded a strategic transaction that integrated Calycé's wind energy teams and acquired a large portion of the project portfolio, with wind and solar activities separated and the solar branch rebranded as Calycé Sun. The company also maintains an international footprint through the Omnicane-Calycé JV Ltd joint venture in Mauritius, targeting 30 MW of wind and 4 MW of solar by 2025 in support of the island's energy independence objectives.

Revenue model

1. Wind Farm Development, Construction & Operation: Calycé develops, constructs, and operates onshore wind farms in the Grand Est region. The company earns revenue from the sale of electricity generated by its wind turbines. It has constructed 13 wind farms (as of 2023) with a total installed capacity of approximately 200 MW (as of 2020). Revenue is generated through long-term power purchase agreements (PPAs) or direct market sales, supplemented by renewable energy certificates.
2. Solar / Agrivoltaic Project Development: Calycé develops ground-mounted solar photovoltaic projects, including agrivoltaic installations that co-locate energy production with active agricultural use. The company has constructed 4 solar central plants (as of 2023). In 2025, the solar branch was spun off into a separate entity called Calycé Sun.
3. Souffle d'Espoir Charitable Wind Revenue Donation: The Souffle d'Espoir project is a charitable wind farm where 100% of operating profits are donated to three regional health associations (Roseau, Vaincre la Mucoviscidose, Institut Jean Godinot). This generates no direct revenue for Calycé but serves as a CSR and community engagement initiative.
4. Fiscal Revenues for Municipalities: Wind and solar farms generate significant fiscal returns for host municipalities. A single 4 MW wind turbine generates approximately €9,000/year for the host commune and €16,000/year for the intercommunal structure (EPCI), creating a recurring local economic incentive.

Core offering

Calycé develops, constructs, and operates onshore wind farms and ground-mounted solar photovoltaic projects (including agrivoltaic dual-use installations) in the Grand Est region of France. The company manages the entire project lifecycle — from site identification and feasibility studies through permitting, construction, and operation — and sells the generated electricity to utilities under power purchase agreements.

Product overview

Calycé operates as a renewable energy development company with two main product lines: wind farm development under the Calycé brand and agrivoltaic solar development under its Calycé Sun subsidiary. The company manages the complete lifecycle of projects from site identification and feasibility studies through construction and operation. Calycé Sun focuses specifically on agrivoltaic projects that combine agriculture with solar energy production. Additionally, the company operates the Souffle d'Espoir initiative, a charitable wind farm project where all profits support healthcare associations.

Products and services

• Calycé Wind Farm Development End-to-end development, construction, and operation of onshore wind farm projects in the Grand Est region of France. The offering includes site identification, feasibility studies using 101m measurement masts, permitting, construction, and operation of wind turbines. Portfolio encompasses 41 wind farms (13 constructed, 113 turbines operational, 200 MW installed by 2020). Customers include municipalities hosting projects, farmers leasing land, and energy utilities purchasing electricity via PPAs.
• Calycé Sun Agrivoltaic Solar Projects Specialized agrivoltaic solar development brand spun off from Calycé in 2025, combining agricultural production with solar energy infrastructure. The offering enables farmers to diversify income through land lease payments (minimum 10 hectares) while maintaining agricultural production, with the added benefit of shade and storm protection for livestock. The product includes free feasibility analysis and full project co-construction without cost to the farmer.
• Souffle d'Espoir Charitable Wind Project A unique 100% charitable wind energy project where six wind turbines are dedicated entirely to funding three regional healthcare associations (Roseau, Vaincre la Mucoviscidose, Institut Jean Godinot). All operating profits from the wind farm are transmitted to these beneficiary associations. The project enables local citizens to participate via the EnerFip crowdfunding platform.

Partnerships

Five partnerships are on record, tiered core and minor.

• OmnicanecoreStrategic or Co-development PartnerCalycé and Omnicane (a historic Mauritian sugar company now listed on the stock exchange and Mauritius's first electricity producer with 120 MW installed capacity) created a joint venture entity, Omnicane-Calycé JV Ltd, to develop renewable energy projects (wind and solar) in Mauritius. The partnership aims for 30 MW of wind and 4 MW of solar by 2025, supporting Mauritius's goal of energy independence. Omnicane also operates a 5.5 MW hydroelectric plant in Rwanda.
• EnerFipcoreGTM or Marketing PartnerEnerFip is a crowdfunding platform dedicated to renewable energy projects. Calycé partnered with EnerFip for the Souffle d'Espoir wind project to enable local citizens to financially invest in the wind farm's construction, creating a participatory citizen ownership model.
