Carlow County Council – Energy Credit Example A total of 1,814,000 kWh savings were generated. Traded as 82% fuel poor Balance were not fuel poor. Energy credits traded in 2014 March as part of tender process for domestic energy credits. Total energy credit sales €308,308 (23.5% of total Project Cost) Deemed energy credits list establishes energy saving by measure. Average social house measures somewhere between 58m2 and 72m2.
