Utilities will go hell for leather to achieve the 25% Carbon quota required by ofgem up to the April deadline ( they will get an allowance of 1.7 t CO for every tonne saved)...........after that they have a leisurely paced 3 yr programme to complete the balance of the 100,000 Ewi units, of which 25% have already been completed.
I might add that carbon is now being traded/auctioned/offered etc at approx £60-70 per tonne......pre xmas £140!
By deduction that will mean job losses, price cuts and many firms, set up for Eco going bust!
BTW, IWI is dead, even more expensive than SW and less efficient.
