What we do

Our in-house expertise and skills, combined with over 15 years’ experience, means we can provide high-quality, centralized and distributed solutions, that are reliable, economical, and safe in every area, including costing, engineering, procurement, management, and quality and environmental processes. We also specialize in self-performing the construction essential to completing projects – such as building roads and crane pads, foundation excavating and backfilling, underground cabling, erecting overhead lines, and installing turbines and solar panels.

We are experts in third-party engineering, procurement, and construction (EPC) and balance of plant/systems  (BOP/BOS) construction services for the renewable energy, transmission, and energy storage industries. We also develop and/or own and operate renewable energy and storage projects.


From inception

to generation

Landowners and communities

We involve the local community in all of our projects by hosting or participating in meetings and maintaining an open line of communication with a wide range of stakeholders. We do this through public meetings, information brochures, site visits, and direct contact with residents, municipalities, and other community leaders. And, where possible, we use local businesses and suppliers on our projects.

We are committed to creating and maintaining lasting relationships with the communities in which we work.

For the projects we work on, we ensure:

  • minimal disturbance to existing land activities
  • restoration of land at the end of a project
  • open communication

"We've had this land in our family for over 150 years. RES has done an outstanding job communicating with me."
