“Applicant’s Name: Grupotec Solar UK 11 Ltd Site Address Land east of Heydon Road, Heydon Proposal Erection of a solar photovoltaic installation of 30 MW output and all associated supporting infrastructure including cable routing, inverters and transformers, fencing, CCTV, and landscaping for temporary period of 42 years.”

Officer report

The site and surroundings

The approximately 50-hectare site is arable farmland near Heydon, bounded by hedgerows, trees, woodland and nearby homes and heritage assets.

“The site has a total area of approximately 50 hectares (ha) and is located on arable farmland to the east of Heydon Road in the parish of Heydon. The village of Heydon is approximately 2 kilometres (km) to the northwest of the site while the centre of Cawston is approximately 1.5km to the south. The site is largely bounded by hedgerows and trees.”

Officer report

What officers advised

Officers advised approval because renewable energy benefits were significant and identified effects could be acceptable through mitigation and conditions, subject to noise being resolved.

“The solar farm proposed by this application will have a generating capacity of 30MW and will provide enough energy to power approximately 7,500 homes and save approximately 13,000 tonnes of CO 2 a year. National planning policy guidance and the adopted policies of the development plan provide in-principle support for renewable energy proposals.”

“The application will have acceptable impacts on the character appearance of the area – including the surrounding landscape character, heritage assets, residential amenity, highway safety, residential amenity (subject to receipt of comments from the Environmental Quality Officer on noise), trees, ecological receptors, BMV land and aviation safety and where reasonable and necessary to make the development acceptable, planning conditions can be used to mitigate impacts…”

Officer report

What people said

Objections concerned farmland, landscape, heritage, ecology, roads, traffic and local disruption, while two representations supported renewable energy and energy security.

“The nature of the site will have a negative impact on the rural landscape and character of a small community. The proposed solar panels will stand 3.3m tall behind metal security fencing with CCTV.”

“The nearby villages of Heydon, Salle and Cawston have been bisected by pipe construction for wind farm cables with interventions on local roads over the last five years, causing considerable disruption, inconvenience and danger to local residents. The connection from the site to the local substation would open yet again such disruption. • There are at least two more solar farms being considered for this same area.”

Officer report

The main planning issues

Officers assessed landscape, cumulative effects, heritage, residential amenity, ecology, agricultural land, highways, flooding and drainage.

“The key considerations in the assessment of this application are as follows:”

“Principle of development • Impact on the character and appearance of the area • Cumulative impacts • Impact on heritage assets • Impact on residential amenity • Trees and ecology • The use of agricultural land • Highway safety • Flood risk and drainage…”

Minutes

Why it was refused

The loss of Best and Most Versatile agricultural land for over 40 years was not considered outweighed by the renewable energy benefits.

“Reason for overturning officer recommendation:”

“The proposed development will result in the loss of Grade 1, Grade 2 and Grade 3a agricultural land – the Best and Most Versatile land – across the site for over 40 years. The loss and impact of losing such a significant area of Best and Most Versatile land is not considered to be outweighed by the benefits of the proposed renewable energy generation.”

Minutes

The members' reasons

The resolution gives these reasons:

  1. Reason for overturning officer recommendation: The proposed development will result in the loss of Grade 1, Grade 2 and Grade 3a agricultural land – the Best and Most Versatile land – across the site for over 40 years. The loss and impact of losing such a significant area of Best and Most Versatile land is not considered to be outweighed by the benefits of the proposed renewable energy generation.
