This briefing summarizes key aspects of policy and challenges regarding solar farms in the UK:

1. Background:

   • Targets: UK aims for legally binding net zero emissions by 2050 (raised from 80% in 2008). Aims to achieve a fully decarbonised power system by 2035, primarily via wind and solar.
   • Capacity: Target is a fivefold increase in solar power capacity (from ~15 GW in 2022 to 70 GW by 2035).
   • Public Opinion: General public supports solar power (~89% agreement), but local community support varies (average ~55%) and opposition can cause delays.

2. Planning Policy (England):

   • Scale: Planning decisions differ based on size (50 MW threshold). Smaller projects (up to 50 MW) are decided by Local Planning Authorities (LPAs). Larger projects (>50 MW) are 'Nationally Significant Infrastructure Projects' (NSIPs) decided by the Secretary of State (SoS).
   • LPAs (Small Scale): Guidance encourages approving developments where impacts are acceptable and recommends avoiding best/most versatile (BMV) agricultural land. Identifying suitable sites should consider environmental and community impacts.
   • NSIPs (Large Scale): The revised overarching National Policy Statement (EN-1) establishes a "presumption in favour of granting consent" for energy NSIPs, strong weight to deployment need, and restrictions on Green Belt (only 'very special circumstances').
   • Land Siting: Solar farms should be located on previously developed, non-agricultural land where possible; low-quality land is preferred over high-quality, especially BMV land, but they aren't prohibited.

3. Planning Policy (Devolved Administrations):

   • Wales: Uses a threshold system (10MW, 10-350MW as 'Developments of National Significance' decided by Welsh Ministers using the National Plan, permitting or consent likely based on similar criteria as England).
   • Scotland: Separate rules depending on size (MW thresholds). Planning policy encourages renewable energy development. National developments (over 50MW) require energy consent from Scottish Ministers.
   • Northern Ireland: Hierarchy based on size (e.g., >30MW 'regionally significant'). Guidance promotes use of appropriate land but continues existing protections for BMV agricultural land; potential to update policies.

4. Impact on Farming and Biodiversity:

   • Land Use: Debate exists. Conservation groups oppose solar farms on agricultural land (BMV in particular), citing food security concerns. Energy groups argue minimal impact on food security. Agrivoltaics (using land for both farming and solar) is seen as potentially beneficial by some, though evidence is still developing.
   • Data Lack: No comprehensive data on total land use (including BMV) by solar farms or agrivoltaics in England.
   • Biodiversity: Potential negative impacts are raised. However, developers are encouraged to enhance biodiversity (wildflower meadows). Studies suggest potential benefits for pollinators.

5. Barriers to Expansion:

   • Grid Capacity & Connections: Identified as the primary barrier by the Environmental Audit Committee, causing delays and costs. Developers face difficulties connecting to the grid (transmission or distribution networks). Queuing issues and insufficient data further hinder progress. The government acknowledges this as a significant issue and is pursuing reforms.

The focus across all levels of government is on facilitating solar deployment while mitigating negative impacts and addressing technical barriers, though challenges often arise from land use conflicts and grid limitations.
