Lessons learnt
Operation of the SEV system with 85% of load covered by wind is possible and stable
3 main business case levers:
1. A small ESS to reduce CAPEX Managing short term variability needs power, but
only little energy
2. Very high wind harvesting Avoidance of > 6000 MWh of diesel generation
3. Avoidance of other grid investments
