# Lezevorc’h ground-mounted photovoltaic power plant, Caudan Publisher: CapexCue Canonical dossier: Dossier reference: release 1 (851b1038-c17e-41cd-ae1f-b42d9ffbcbf3) Released project intelligence Oldest supporting observation: 2026-10-03T18:20:51.036223+00:00 Dossier released: 2026-10-15T18:27:58.226067+00:00 Source report dates and capture dates are listed per fact below; neither establishes an event date. ## Project summary Luxel’s proposed Lezevorc’h ground-mounted photovoltaic plant is in southern Caudan, Morbihan. The IGEDD environmental authority adopted an advisory opinion on 28 August 2025; the opinion is not an authorization decision. The proposal combines reshaping and capping a former demolition-waste site with a solar installation. The opinion describes 5,049 modules over 3.61 ha, with stated capacity of 3.11 MWp and estimated average production of 3,515 MWh per year. It reports an estimated 250,000 m³ of waste, whose detailed characterization was incomplete, and says some deposits remain outside the project boundary. The authority highlighted unresolved assessment and protection issues, including waste characterization and geotechnical stability, runoff and downstream flood effects, and safeguards for wetlands and aquatic environments near the mounds. These are concerns raised in the 2025 opinion, not evidence that they have since been resolved. The source is the environmental authority’s opinion adopted 28 August 2025; it does not establish subsequent project or permitting status. ## Evidence limits and unknowns - As of the 28 August 2025 opinion, the building-permit and coastal-law derogation outcomes were not established; the derogation was still under instruction and its request was not included in the file referred to the authority. Current status after that date is not established by this source. - The authority said the project’s various site, cleanup, and solar-plant perimeters needed clearer definition; the opinion also reports that waste remained outside the project boundary in the northwest. - The full quantity and characterization of waste, material quantities and their sources or destinations, geotechnical results, and final foundation design are not established in the reviewed opinion. - The final grid-connection option, substation capacity, and any required network reinforcement are not established in the reviewed opinion. - The reviewed opinion does not identify a construction contractor, procurement arrangements, project investment, or financing; it also does not establish a buying window. Current purchasing availability: unknown. Source-dated plans do not establish current progress or available supplier packages. ## Project metadata Country: France Region: Europe Physical assets: Solar PV Derived from the exact released evidence; unresolved fields remain unclassified. ## Project category Energy Derived from the reviewed scope statement; delivery stage remains unclassified. The proposal combines reshaping and capping demolition-waste mounds with installing a solar plant. The planned works include forming a northeast-facing platform at a 3% slope; covering it with 20 cm of clay and 10 cm of topsoil; removing visible waste around the site, including in the wooded wet valley; and installing 5,049 photovoltaic modules on a fenced 3.61 ha area. Associated facilities include an 18 m² technical building, a 191 m central gravel road, a 591 m perimeter fire-access road, and a 120 m³ fire-water tank. The plant is described as 3.11 MWp, with average production estimated at 3,515 MWh/year. The report says waste remains outside the project boundary in the northwest, and notes that the choice not to treat all deposit areas is unexplained. The grid connection is not settled: an approximately 2.5 km underground connection to Maneguen substation is envisaged, with other options also mentioned. Foundation descriptions differ in the dossier: supports are described as probably ballasted, but elsewhere as steel tables attached to concrete blocks resting on the ground.

The assessment identifies a wetland of about 150 m² and iron pollution in the stream; the authority says effects on wetlands and aquatic environments near the mounds need clearer protective measures, and calls for fuller assessment of runoff and impacts downstream. The proposal describes retaining perimeter woodland and avoiding the identified wetland, but the project’s cumulative effects with the separately planned Kerpont development-zone extension to the south are also noted.

The reported waste estimate is about 250,000 m³, while its detailed characterization is incomplete.

The source says responsibility for decontaminating the site rests with the landowner, who is not named.

A building-permit application had been submitted to the Morbihan prefect, and a derogation from the coastal-law urban-continuity principle was still under instruction; the opinion says the derogation request was not included in the file referred to the authority. Caudan’s planning zone is described as agricultural, with rules preventing the proposed new installation, and a procedure to make the local plan compatible had been initiated. A public inquiry was to be held, but a joint inquiry with the planning-plan compatibility procedure was not the approach chosen. No water-law procedure was envisaged by the project owner, which the authority flags in light of the site’s planned impervious area. The authority’s opinion is advisory, not an authorization decision.
