Almost three quarters of electricity generated in Ireland on Saturday came from wind during Storm Denis, but not all of it could be used to power the grid. There is a limit on how much energy from renewable sources can be used at any one time. This is called the SNSP (system non-synchronous penetration) limit and it stands at 65 per cent. EirGrid plans for this to be increased to 70 per cent by the end of the year and 95 per cent by 2030. Last year 8 to 9 per cent of wind energy generated in Ireland had to be “turned down” due to the limit, according to an industry expert. On Saturday 73 per cent electricity generated in Ireland came from wind and the excess was exported to Britain via an interconnector. There are plans to build a “Celtic interconnector” linking to France.
