FEP first contract to study potential renewable energy projects

This funded study from Nov 2016 to July 2017 focuses on the feasibility of installing roof-top photovoltaic (PV) systems in Cornwall. The study examines the low planning issues associated with PV on roof-tops, the potential income from Feed-In Tariffs, and the high daytime electricity use on-site. The study also explores community engagement, financial projections, and the assessment of community benefits. The chosen technology for assessment is PV due to its suitability in the area with high solar radiation. The study concludes with the need for non-commercial funding and identifies potential community benefits and carbon savings.

  1. FEP first contract to study potential renewable energy projects WRAP funded study Nov 2016 to July 2017 PV on roof tops has low planning issues Low income potential from Feed In Tariffs drove search High daytime on site use of electricity most likely to be viable Cornwall has high renewables installation rate creating grid access issues

  2. Required actions under funded study Community engagement Assessment of community benefits Chosen technology assessment Site finding & assessment Financial projections Conclusions & future actions

  3. Community engagement included:- • Meetings with Falmouth & Exeter Universities • Meetings with potential project partners in Falmouth Docks • Presentations to Falmouth & Penryn Town Councils • Attendance at Falmouth Business Club • Presentation & discussion at Falmouth Café Sci • Meetings with Transition Falmouth • Appearance & discussion on Source FM radio

  4. Chosen technology assessment Our survey found roof top PV is well supported by members & the wider community PV is eminently suitable for this area as Cornwall experiences a high incidence of solar radiation Some sectors have higher demand in the summer when the PV supply is high: eg tourism and catering

  5. Site finding and assessment Assessed locations

  6. Chosen technology assessment • Good technical potential for larger commercial roof tops However • we were late to the quest for local PV • many organisations have already considered, installed or rejected PV • many roof tops are leaking- poor build quality or old • larger organisations get cheaper electricity • reducing our room for viability • larger organisations tend to be upcountry owned • dramatically reducing our ability to get through to the right person • larger organisations are more likely to have specialist energy staff • already considered PV

  7. Smaller commercial potential • Late in study we assessed some smaller projects <50kW • can get a better tariff in FITs • therefore not so dependent on host daytime electricity demand • easier to connect to the grid • But – is much slower to get to our 2MW installed target • lower carbon savings • lower local spend and return • Is possible now

  8. Financial modelling: parameters • commercial & community funding return needs • using up to date commercial quotes for capital & operating costs • using expected reduction in capital costs, beyond present • using best estimate of PV output for each location allowing for shading, roof restrictions, permitted development restrictions

  9. Financial modelling: results • very poor results for most sites • unable to provide returns for FEP or local community • income too low to use commercial funds • larger organisations have very low cost electricity with which it is hard to compete

  10. Financial: conclusions Therefore we need non commercial funding • crowdfunding • grant aid • long term equity accepting low returns for some years This is approach is suited to community and other well supported locations

  11. Assessment of potential community benefits Reduced electricity bills for project partners Lower electricity bill increases over time Reduced carbon emissions Potential funds for community activities

  12. Community benefits: carbon savings potential potentially 1 MW PV installed and nearly 500 tonnes pa CO2e savingsif we can work out the financing
