Cowdown Green Energy will produce biomethane to support the transition to net zero. This is a green fuel that will support our transition to net zero and reduce our dependence on foreign gas supplies. Our revised proposals now include a direct connection into the grid further improving security and reducing proposed traffic movements.

Our plans will generate enough renewable gas to heat over 9,000 homes.

We are ensuring where we can that we support local business and employ local people.

We will work hand-in-hand with the local farming industry, providing local farmers with guaranteed revenue and natural fertiliser.

Cowdown Green Energy will take organic material, including crops from rotations and manure, from local farms to feed the plant. The same farmers will benefit by receiving the natural fertiliser produced at the end of the gas generation process. This will reduce the amount of expensive and imported artificial fertiliser that local farm businesses need to buy, improving soil health, enhancing food security and storing more carbon.

We’ll also create 15 Full Time Equivalent jobs, and support 35 further jobs through the supply chain.

We initially submitted a proposal for development on this site in December 2022. That application was subsequently withdrawn, and since then we have been working closely with the local council, statutory consultees, and local Parish Councils to revise the scheme in response to the feedback received.

A revised planning application has been submitted at the end of March 2025. Within this, we have demonstrated how we have listened to the views of local communities and stakeholders.

The new proposals represent a complete redesign of the original scheme. They retain the significant benefits of clean, renewable energy generation - helping to tackle climate change and support the rural economy - while substantially reducing the scale, height, and massing of the development to lessen its local landscape impact. In addition, the revised scheme includes significant improvements to highway safety in line with advice from both Hampshire County Council Highways and National Highways, who have confirmed these would be a betterment.

We’ve listened to the feedback from our previous application and taken steps to reduce the impacts of the proposal, with fewer tanks, most of which are lower, minimising the impact on the landscape, but kept all the benefits to the environment and the rural economy.

We’ve also reduced the number of covered lagoons which will reduce our impact on Air Quality.

The buildings won’t look out of scale from the type of structures, such as barns, often seen on commercial farms. The proposal is generally smaller in scale, height and mass than our nearby Three Maids renewable gas generation facility near Winchester.
