List of 3 large renewable energy developers in the United Kingdom

Due to the UK’s geography and climate, many renewable energy developers are based in the UK. Onshore wind projects in particular, are carried out by these developers, so these companies tend to have a lot of experience. This article looks at the top three renewable energy developers in the UK.

1. Lightsource BP (London)

The pioneer in developing solar energy parks, Lightsource BP, was able to realize renewable energy projects in 14 countries. Based on their mission to transform energy generation more sustainably, the developer implements the projects by using the newest technologies. While aiming for renunciation from the emission generation energy supply chain, the London-based developer strives to drive the energy transition forward. During the last years, Lightsource BP was able to develop solar projects with a total capacity of 11.5 GW and a 58 GW global solar development pipeline. In 2023, Lightsource sold a finished solar project in the UK involving 300 MW of installed capacity to the global energy producer Sonnedix.

2. OnPath Energy (Durham)

Banks Renewables was acquired by Brookfield Asset Management in December 2023 and is now rebranding as OnPath Energy. OnPath Energy has outlined its extensive pipeline exceeding 3GW of renewable capacity, including 12 operational onshore wind farms across Scotland and England. Today, the Durham-based renewable energy developer OnPath Energy is involved in all stages of project development, working closely with landowners. The company has a wide range of expertise and develops wind, solar and battery storage projects.

3. Green Investment Group (Edinburgh)

Sydney-based Macquarie Group Limited has acquired Green Investment Group after five years in the green infrastructure space. As a result, the Edinburgh-based developer represents one of the world’s largest dedicated green infrastructure investor and developer teams, with the overall aim of accelerating the energy transition. While GIG manages renewable energy projects worldwide, its portfolio of developed projects includes offshore wind farms, solar farms and onshore wind farms. The offshore wind farms alone produce approximately 8GW of wind energy.

Developers for Renewable Energy in the United Kingdom

The need for renewable energy sources is pressing all over the world, including the UK. To deliver effective projects, project developers are needed – from the selection of suitable sites, through design, to the actual planning of renewable energy sites such as solar or wind farms, or other green energy sources such as biomass, hydro, tidal and geothermal energy.
