Knowl Green Solar Farm

Clean energy with benefits that go beyond the grid

Knowl Green Solar Park is a 49.99MW solar project at Baker’s Road, near Belchamp St Paul in Essex. The site generates enough renewable electricity to power approximately 12,500 homes each year while avoiding around 11,000 tonnes of CO₂ emissions annually.

Alongside clean energy generation, Knowl Green has been designed to create more space for nature, strengthen local habitats and support the surrounding community. As an independent power producer, we own and operate our projects for the long term, keeping us responsible for the energy we generate and the land around it.

Designed to work with nature, season by season

Knowl Green has been designed to generate clean energy while creating more space for nature, with habitat improvements expected to deliver 234% Biodiversity Net Gain. 

Existing hedgerows will be strengthened with native, species-rich planting, closing gaps and creating more continuous wildlife corridors. Plants including honeysuckle and traveller’s joy will provide nectar, berries and shelter throughout the seasons, supporting insects, birds and bats. 

Native tussocky grassland will add further habitat across the site, creating nesting opportunities for skylarks while supporting other wildlife such as hedgehogs. Additional tree planting along the southern boundary will also provide greater screening from Baker’s Road. 

Supporting skylarks

Skylarks are among the notable bird species recorded at Knowl Green and are a particular focus of the site’s ecological management. 

The grassland is being managed to provide suitable nesting habitat for this red-listed species. Dedicated skylark monitoring has already begun and will continue in Years 1, 3, 5 and 10, helping us understand how skylarks use the site and informing its long-term management. 

How many species can you spot?

Knowl Green supports a varied mix of wildlife, with 74 bird species recorded during breeding and wintering surveys, alongside mammals, bees, butterflies and other invertebrates. Explore some of the species recorded around the solar park in our gallery, then discover more below.

Kestrel

Kestrels are a familiar sight over open countryside, often spotted hovering while searching for small mammals and insects below. The grassland and field margins around Knowl Green provide valuable foraging habitat for this distinctive bird of prey.

Skylark

Known for their unmistakable song, skylarks are ground-nesting birds that rely on open grassland and farmland habitats. At Knowl Green, grassland management and dedicated monitoring are helping us understand how skylarks use the site over time.

Brown hare

Brown hares are well suited to open farmland, using their speed and powerful hind legs to move quickly across the landscape. They are one of the mammals recorded around Knowl Green and can be spotted across grassland and field habitats.
