Feed-in Tariffs (FiTs)
• FiTs scheme introduced 1 April 2010
• Subsidies to encourage deployment of
small scale (<5MW) low carbon electricity
generation
• Cost shared among electricity suppliers
according to their market share, with costs
ultimately passed on to consumers
• Focus on organisations, businesses,
communities and individuals who have not
traditionally engaged in the electricity
market
• Attractive subsidies led to significant activity
by developers of 5MW solar PV farms
• However, recent Government review
significantly reduced tariff (more on this
later…)

URS Scott Wilson Experience
Major commission October 2010 to April 2011 with one developer client:
• 11 sites across Devon and Somerset
• EIA screening opinion requests – EIAs not required
• Ecology, landscape, heritage and flood risk assessments
• Multidisciplinary design workshops to minimise environmental effects

EIA Screening Reports prepared and submitted with Screening Opinion requests
• Schedule 1? No
• Schedule 2? Not specifically, but our interpretation was Yes under Part 3a
“industrial installations for the production of electricity, steam and hot water”
• [Note: Cornwall Council also interpreted Yes but under Part 1a
“use of uncultivated or semi-natural land for intensive agricultural purposes”, mainly because Circular
2/99 referred to development “such as greenhouses”.]
• Within a Sensitive Area? No, deliberately so
• Meet or Exceed Threshold? Yes, sites typically 15 to 20 hectares
(threshold 0.5 hectare)
• Significant Effects Likely? Although there would be some environmental
effects, robust arguments were made such that these would not be “significant”
in EIA terms

Ecology
Extended phase 1
habitat survey and
desk study
Wintering birds survey
Designs retained
hedges and trees
Recommendations for
timing of vegetation

Heritage
Built heritage – potential setting impacts
Historic landscape – close liaison with landscape architect
Archaeology – potential physical impacts

Flood Risk and Hydrology
• Sites chosen to be in Flood Zone 1 – low risk from fluvial, no risk from tidal
• Increase in impermeable area not significant, nevertheless SUDS proposed in
the form of cut-off trenches and swales to avoid impacts on adjacent land

Final Designs and Planning Applications
Environmental assessments complete?
Site layouts and design details finalised?
Planning documents ready?
Planning applications submitted? Not yet, but maybe….
