United Kingdom & Ireland

RES has been at the forefront of the renewable energy sector since the early 1980s. Since then, we’ve grown to become one of the largest independent renewable energy developers in the UK and Ireland.

About us

RES has been at the forefront of the renewable energy sector in the UK and Ireland since the early 1980s. We developed the UK’s second ever wind farm, in 1992 at Carland Cross in Cornwall – and since then, we’ve grown to become one of the largest independent renewable energy companies in the UK and Ireland. We currently have more than 1,000 MW (megawatts) of renewable energy projects constructed, under construction or at advanced planning stages.

We’re involved in a range of renewable energy technologies, including onshore wind, solar, offshore wind, wave and tidal, as well as enabling technologies such as energy storage and demand side management. Across all of these, our reputation for quality and reliability is second to none.

What we do

We aim to be at the leading edge of the transition to a low-carbon economy across the UK and Ireland by generating renewable energy and supporting the technology that creates it.

We’ve developed and built over 40 wind and solar farms, and operate over 20 assets for a range of clients. We also provide development, engineering, construction, and asset operation and maintenance services for utility-scale onshore and offshore windsolar, and energy storage installations.

Over 20 years of offshore expertise gained in rounds 1, 2 and 3

 

Our first UK solar farm opened in 2014, and we have a portfolio of consented solar projects. We have the resources and project management capabilities needed to develop, construct, and operate solar farms for large-scale power generation connected to the grid, and for on-site commercial solar installations for industry.

We’re also pioneers in utility scale energy storage that provide a multitude of grid services. Our experience in operating centralized renewable energy projects and understanding network requirements means we can integrate and operate energy storage schemes efficiently. 

Exploring different ways to increase energy efficiency, we’ve invested in a smart grid company, to offer demand side management. Our new service optimizes and shifts energy consumption by controlling millions of devices, minimizing energy costs and increasing revenues.

Landowners and communities

Wherever we work, we talk to local people about what our projects mean to them, and how they can bring tangible benefits to their communities.

We do this through public meetings, information brochures, site visits, and direct contact with residents, charities and schools. And, where possible, we use local businesses and suppliers on our projects.


We also support community charity initiatives with funds from wind farm revenues.

  • regular income
  • minimal disturbance to existing land activities
  • complete project management
  • greener energy
  • contributions towards reasonable legal fees
  • restoration of land at the end of a project’s lifecycle.
