D3Energy

D3Energy is a United States-based solar-energy developer focused on floating photovoltaic projects, often abbreviated as floating PV or FPV. The company was founded in 2013 and entered into a partnership that year with the French water-based solar specialist Ciel & Terre. Through this relationship, D3Energy develops and distributes floating-solar systems in the United States, with activity initially concentrated in states including Florida and New Jersey and later extending to additional regions and international projects. The company’s work is centered on Ciel & Terre’s Hydrelio system, which uses high-density polyethylene floats to support solar modules on water. Rather than operating only as an equipment reseller, D3Energy’s stated scope covers multiple stages of project delivery. These activities include engineering, project development, operations and maintenance, financing, procurement, and construction. Its customers and project partners include water utilities, public agencies, and other organizations that can use reservoirs or treatment-plant ponds for solar generation. Floating solar allows photovoltaic generation to be deployed on water bodies where ground space may be constrained or where an existing utility site can support the project. D3Energy’s projects demonstrate this connection with water infrastructure. In 2017, the company and Ciel & Terre installed a 31.5-kilowatt-peak floating array for the Orlando Utilities Commission in Central Florida. The installation was described as Florida’s largest floating solar photovoltaic system at that time. D3Energy expanded its project footprint in 2024. It completed what was described as Ohio’s first floating photovoltaic array for Del-Co Water at the Signal Hill Water Treatment Plant. The project, opened in December 2024 after completion in September, combined the floating system with rooftop and carport solar installations and was reported to offset approximately half of the treatment plant’s electricity requirements. In the same year, D3Energy worked with Ameresco on Utah’s first floating photovoltaic installation for the Mountain Regional Water Special Service District. The company also completed a floating-PV project for Orange County Utilities’ Southern Regional Water Supply Facility in the southeastern United States and reported work in New Zealand. The company’s activities also received attention after Hurricane Milton in Florida in 2024. D3Energy reported that ten of its installations located in the storm’s path remained undamaged and operational, contrasting with damage reported across some conventional, ground-mounted solar installations in the state. This statement positioned the company’s floating installations as resilient infrastructure, although the available reference material does not provide an independent engineering assessment or a broader performance comparison. D3Energy’s identity is therefore closely associated with the commercialization of floating solar in North America, particularly for utilities and water-treatment facilities. Its business model combines development and implementation services with the deployment of a partner’s proprietary floating platform. Available reference material does not establish a public listing, ownership structure, executive roster, revenue figures, or a separate consumer-facing product portfolio. The company is best understood as a specialist clean-energy project developer and integrator rather than as a mass-market solar-equipment brand.

D3Energy was established in 2013 as a United States-focused developer of floating solar projects. In its founding period, the company formed a partnership with Ciel & Terre, a French company that had developed floating photovoltaic technology based on high-density polyethylene floats. Ciel & Terre’s Hydrelio platform was designed to support solar modules on water and had been developed for larger-scale solar applications during the preceding decade. D3Energy became the American development and distribution partner for the system, initially concentrating on markets such as Florida and New Jersey. The partnership gave D3Energy a role that extended beyond the supply of floating structures. Its project responsibilities include engineering, development, financing, procurement and construction, as well as operations and maintenance. This integrated approach has allowed the company to target water utilities and treatment facilities, where available water surfaces can be combined with existing electrical infrastructure and solar demand. A notable early project was completed on February 18, 2017, when D3Energy and Ciel & Terre installed a 31.5-kilowatt-peak floating array for the Orlando Utilities Commission in Central Florida. The project was identified as the largest floating solar photovoltaic system in Florida at that point and served as an early demonstration of the partners’ technology in the United States. D3Energy’s later work broadened the geographic and institutional reach of floating PV. In 2024, the company completed a project for Del-Co Water at the Signal Hill Water Treatment Plant in Ohio. The installation was described as Ohio’s first floating photovoltaic array. It was completed in September and opened in December, alongside rooftop and carport solar installations. The combined deployment was reported to offset approximately half of the treatment plant’s electricity needs. The company also completed Utah’s first floating photovoltaic installation in September 2024. That project was developed with Ameresco for the Mountain Regional Water Special Service District. During the same year, D3Energy completed or reported additional floating-PV work for Orange County Utilities’ Southern Regional Water Supply Facility in the southeastern United States and in New Zealand. Weather resilience became another aspect of the company’s public profile after Hurricane Milton struck Florida in 2024. D3Energy reported that ten of its installations located along the hurricane’s path remained undamaged and operational. The available account does not provide detailed technical measurements or an independent verification, but the report highlighted the operational continuity of those projects during a severe weather event. The available reference material presents D3Energy as an active specialist developer and integrator rather than a diversified energy conglomerate. It does not identify the company’s founders, senior executives, ownership structure, revenues, public-market listing, or standalone consumer products. Its historical development is primarily defined by the Ciel & Terre partnership, the deployment of Hydrelio-based systems, and the expansion of floating solar into water-utility projects across the United States and selected international markets.
