Provisional results from the fourth round of the Irish Renewable Energy Support Scheme (RESS 4) reveal that approximately 1,334 MW of onshore renewable electricity won support.

Of that total, 960MW of solar PV and 374MW onshore wind was procured at an average auction price of €96.85 (£81.73) per MWh, lower than the two previous auctions. The generation-weighted average price for solar projects was €104.76 per MWh.
