Background And Description Of Proposal 1.1 This application proposes the construction and operation of a photovoltaic (PV) solar farm which would produce electricity for export to the National Grid. The proposals would involve development on a parcel of land generally located to the north of the former Petroplus refinery site and to the east of Fobbing Marshes. The basic details of the planning application are summarised in the table below: Site area Gross site area – 11.8 Ha Area occupied by PV panels – 8.8 Ha Maximum no. of PV rows Approximately 50 rows across 2 parcels of land Power Output 5 MWp (sufficient to supply up to 2,150 homes) Ancillary development 2 x Inverter and MV Stations comprising an inverter (max. 8.75m (l) x max. 2.5m (w) x max. 3.15m (h)), transformer (1.9m (l) x 1.7m (w) x 2.45m (h) and cabinet (max. 3.1m (l) x max. 2.4m (w) x max. 3.5m (h)) 1 x control cabinet (max. 7.5m (l) x max. 4.7m (w) x max. 3.1m (h)) 1 x storage container (max. 7.2m (l) x max. 3.45m (w) x max. 3m (h)) Perimeter fencing max. 2.5m high CCTV columns max. 4m high (40 no. in total) Internal access tracks Planning Committee 14 January 2016 Application Reference: 15/00877/FUL 1.2 The proposed installation would provide up to 5MWp of electricity which is to be supplied to the National Grid electricity network. The application suggests that the solar farm would generate enough electricity for an estimated 2,150 homes. Planning permission is sought for an operational period of 25 years, after which it is proposed to remove the PV installation, with all of its supporting infrastructure, and restore the land to its current state. 1.3 The development involves the installation of PV panels or modules in a series of rows aligned east to west, the rows are referred to as PV arrays. Detailed specifications of the panels proposed at the site have not been provided. However, a typical PV panel measures approximately 1.6m x 1m. The panels would be fixed and stationary and would not track to follow the movement of the sun. The panels would be mounted on an aluminium framework which would be assembled on-site such that the panels are tilted to face south at an angle of approximately 20o from the horizontal. The panels would be positioned between 0.8m-1m above ground level and to a maximum height of 2.3m above ground level. Each row of panels would be separated by a clear corridor measuring between 3.4m and 4.4m. A site layout drawing suggests that a maximum of 40 rows of panels would be provided, split into two separate ‘banks’ of 28 rows and 32 rows. However, the precise number of PV panels and rows on the sites would be determined at the detailed design stage taking into account topography, shading and mitigation measures. Columns supporting the frames which hold the panels will be sunk some 1.5m into the ground to provide stability against wind resistance. 1.4 The illustrative site layout drawing suggests that the PV arrays would be arranged on the site to maintain a clear corridor to the site boundaries. Additional clear corridors would be maintained adjacent to watercourses which bisect the site on land within the control of the applicant, although outside of the application site. 1.5 Rows of PV panels would be connected to an inverter which would convert DC output from the panels to AC. A total of 2 inverters are proposed and each would be housed in an enclosure with a transformer. A grid connection control cabin would be provided together with a distribution network operator sub-station, located at the south-western corner of the site in order to export power from the development to the national grid. The applicant states that connection to the National Grid will be via an underground cable linking to an existing UK Power Networks’ sub-station located close to the A1014 roundabout junction south-west of the site. Planning Committee 14 January 2016 Application Reference: 15/00877/FUL 1.6 The boundaries of the site would be secured by maximum 2.5m high galvanised steel mesh deer fencing. The fencing would incorporate mammal access points and at locations where the internal access track bisects the boundary fence a welded mesh steel gate (coloured moss green) would be provided. At intervals around the site perimeter CCTV cameras would be mounted on top of poles, with each pole a maximum of 4m in height. A total of 40 cameras would provide surveillance for the site. 1.7 Access into the site would be taken from an existing private road serving Thames Oilport which forms the north-eastern arm of the A1014 roundabout. Gravel access tracks would be constructed within the site to be used during construction, operation and de-commissioning of the solar farm. The construction phase of development would last for approximately 12 weeks. During operation, there would be occasional visits to the site for security and maintenance purposes. 1.8 Process The application proposes development subject to the Environmental Impact Assessment (EIA) Regulations, therefore, the application has been accompanied by an EIA. The EIA considers the environmental effects of the proposed development during construction and also when operational and includes measures either to prevent, reduce or offset any significant adverse effects on the environment. The findings of the EIA are presented in an Environmental Statement (ES) submitted with the application. The ES is accompanied by a number of technical appendices. The contents of the EA are listed in the supporting documents section of this report. 1.9 The Council has a statutory duty to consider environmental matters and an EIA is an important procedure for ensuring that the likely effects of new development are fully understood and taken into account before development proceeds. EIA is, therefore, an integral component of the planning process for significant developments. EIA leads to improved decision making by providing the development control process with better information. EIA not only helps to determine whether development should be permitted but also facilitates the drafting of planning conditions and legal agreements in order to control development, avoid or mitigate adverse effects and enhance beneficial effects. It is vital that the environmental issues raised by the application are assessed in a robust and transparent manner. 1.10 In order to fulfil the requirements of the EIA Regulations it is necessary to ensure (a) that the Council has taken into account the environmental Planning Committee 14 January 2016 Application Reference: 15/00877/FUL information submitted, and (b) that any planning permission granted is consistent with the development which has been assessed. To achieve this second objective the Council has the ability to impose conditions and secure mitigation measures by Section 106 obligations. 2. Site Description 2.1 The application site generally comprises an area of open land located to the north of the Thames Oilport / Thames Enterprise Park (former Coryton refinery) site. The site is irregular in shape and consists of an unused area dense scrub, scattered scrub and poor semi-improved grassland. Small areas of standing water are located with the site and drainage ditches and watercourses principally form the northern and western site boundaries. The site is not used for agricultural purposes and appears to have naturally developed a scrub habitat after former uses on the site ceased. 2.2 Historically, the site formed part of Corringham and Fobbing grazing marshes. From the 1890’s the site formed part of the Kynoch munitions manufacturing and storage factory complex.
