Who are we?

Strong commitment to communities

Still Constructing: 500MW in Scotland

8 projects, our largest construction period ever. Large scale projects and Extensions

Once complete bring portfolio to 2GW

Life Extension through Repowering

Repowering sits as one subset of Life Extension which often entails the removal of the original site turbines, and usually requires the need to secure additional grid capacity:

Repowering our assets

Life Extension: Over arching term encompassing various

• pportunities to extend the life of an existing site.
• 1. Extent of change required to a site’s design is very site specific.
• 2. The scale of any EIA required needs to be proportionate to the

extent of change, and any resultant significant effects. Beyond 25 years: Asset Integrity Inspections and Turbine Efficiency.

Quick and efficient consenting process

Repowering our assets

Replant: Points to Consider

Utilise new turbine technology where possible Future proof landscape capacity studies Local supply chain growth Bonds/Restoration/Decommissioning Community Projects continue to grow/investment? Site suitable for use in perpetuity Not one size fits all

7

Replacement of 6 G47 (660kw) with 2 G97 (2MW) turbines

Repowering our assets

Case Study 1 – Serra da Panda Windfarm (Spain)

Full EIA not necessary: No consultee response to Scoping

Partial decommissioning New turbine erected

Road extended by 1m with new foundation/hardstanding

8

New Design: Points to Consider

Route to market is essential

Repowering our assets

What forms the baseline: in perpetuity? Supportive National guidance required or risk investor confidence New bases, hardstanding and access tracks required. Turbine manufacturers developing larger turbines. Grid infrastructure investment

Case Study 1 –Carland Cross

Repowering our assets

Additional cost of removing bases, tracks and landscaping Widened roads and used existing control building/access Commissioned in 1992 - 15 turbines (400KW) for 10 (2 MW)

10

Recycle turbines through auction to India or Cuba market

Repowering in Spain

Case Study 2 – Malpica Wind Farm (Spain)

Commissioned in 1997 replacing 69 G47 with 7 E92 (2,35 MW)

Case Study 3 – Cabo Vilano Wind Farm (Spain)

Scoping type document used to determine EIA LVIA: Existing turbines vs Repower = Significant visual impact reduction concluded by environmental Authority Commissioned in 1990 replace 22 (<200KW) with 2 V90 (3MW)

New route to market to utilise new technology where possible

Conclusions

Conclusions and Recommendations

Quick and easy consenting Not one size fits all, as there are multiple options Reset expectations or always use old technology Communities have a role to play Grid infrastructure needs investment Need to maintain and build on renewable targets
