Our customers and partners reflect on 20 years

RES has been a key partner for Innagreen in Canada since 2021. Innagreen has purchased two high-quality construction-ready wind farms from RES during that time. Both wind farms had been well-developed to high standards. We then used RES' construction team to build the projects; they delivered a high-quality build, on time, with solid subcontractors, that fully met our needs. Now that the projects are operating, we use RES' Asset Management and O&M Services. This turnkey service has been critical to the success of our business, and we look forward to working with RES in the future on many more projects across Canada.

Michael Capaldo, Vice President, Construction and Engineering

Innagreen Investments

Our investment in this project (Bekevar) not only strengthens our community’s economic portfolio, but it also reduces carbon emissions in Canada and reinforces our role as Indigenous Peoples to act as stewards to the land, waters, and air.

Cadmus Delorme

Former Chief of Cowessess First Nation

From 2017 to 2022, I had the privilege of collaborating closely with both the project development and EPC divisions of RES in Canada. My employer, the Owner, partnered with RES to submit bids for several sites in provincial renewable energy calls in two provinces.

The resource assessment and development team at RES demonstrated unparalleled expertise. Following our successful bids, the EPC segment of the project maintained this exemplary working relationship, adeptly managing the inevitable challenges that arose during construction.

The most commendable aspect of my interactions with RES throughout the project lifecycle was their consistent ability to "think like an Owner." They approached each challenge with a collaborative spirit, never assigning blame or adopting the mindset that a particular issue was solely the Owner’s responsibility. Instead, they engaged with a constructive attitude that emphasized overcoming project-related challenges together.

Additionally, RES completes and sells the 184MWdc Big Sky Solar Project in Alberta to TotalEnergies, supporting a broader renewables partnership. RES also launches its Indigenous Reconciliation Action Plan.

Protecting the hazel dormouse in Germany

The hazel dormouse is one of Germany’s rarest forest dwellers, vital for biodiversity but threatened by habitat loss. At a wind farm in south-west Germany, our team worked with care to create new shelter and nesting sites to support this species. To enhance the suitable dormouse habitat, we created well-structured forest edge areas and planted additional fruit-bearing shrubs. In addition, 48 nest boxes were installed on the trees, which have already been accepted by the dormouse. This initiative forms part of our broader biodiversity efforts featured in the 2025 Sustainability Report.

Protecting Swift Parrots in Australia

During the development of a renewable energy project in Australia, comprising a wind farm, solar farm, and battery energy storage system, we conducted habitat assessments to identify the presence of the critically endangered Swift Parrot and map native vegetation. The project has undergone several design refinements to minimise impacts, including preserving 28 large trees in patches and 46 scattered trees, and increasing buffer distances to high-quality foraging habitat. A 300 metre buffer has also been applied to the Joel Joel Nature Conservation Reserve, with future layouts aiming to further increase buffers and reduce turbine density in sensitive areas.

Protecting the Great Noctule bat in France

The Great Noctule is a protected bat species in France, as are all chiropterans. At a wind farm we manage in the centre of France, our asset management team works to conserve this species in the area. Following a scientific study, systems were put in place to regulate turbine operation based on the behaviour of the Great Noctule to reduce the risk of mortality. In 2022, we carried out additional monitoring during the species’ peak activity period, from mid-July to mid-September, using BATmode from the nacelles to record bat calls and assess activity. This study supports efforts to improve knowledge of chiropteran behaviour at the site and more broadly across France.

Protecting the Dulacca Woodland Snail in Australia

During the development of the Dulacca Wind Farm in Australia, we carried out survey and habitat assessments to map known and potential habitat for the endangered Dulacca Woodland Snail, focusing on avoiding these areas to minimise impact. A collaborative effort between RES, the contractor and specialist consultants reduced the proposed direct impact to snail habitat by over 95%, with a three-hectare ecological offset area created for the small residual area affected. Our work also involved extensive engagement with the Barunggam People, the Traditional Owners of the land, leading to a final design that avoided more than 90% of mapped high-density Aboriginal artefact scatters and 100% of identified scar trees, stone procurement areas, and grinding grooves, ensuring these culturally significant sites remained undisturbed.
