Dr Fred Udo, a distinguished engineer from CERN in Geneva, now retired, has published a new analysis on the Irish electricity system. In his previous report (link here), he used CO2 emission data from Eirgrid to show the inefficiencies created in the system by adding more wind. In this latest report, he uses fuel input data from SEAI to show that the Eirgrid data actually underestimates CO2 emissions by about 6% and therefore the losses referred to in his previous report were too low.
The conclusions are really a damning indictment of the energy policy that resulted in such huge investment in wind and interconnector infrastructure. There is also an added sting in the tail - the investment of billions of Euros in new CCGT plant that could consume fuel more efficiently than before has been pretty much a waste because they have been forced to run inefficiently.
The performance of the system in 2011 shows clearly, that without the extra windmills and without the EDW link, but with the new CCGT gas units operating one does better than with all the new wind turbines and EDW link.
