ENERGI E2 ENERGI E2 –– KeyKey figuresfigures
• Largest power generating company in Eastern Denmark• 7 large- and 10 small-scale power plants in Eastern Denmark -
mainly Combined Heat and Power (CHP)• Generating capacity (Europe), electricity:
– 4,500 MW • Generating capacity (Denmark), heat:
– 2,600 MJ/s (district heat)– 1,800 t/h (steam)

Target for the use of biomass in Danish power plants by 2000:1,2 mil. tonnes of straw0,2 mil. tonnes of wood chips
Additional agreement by July 1st. 1997:0,2 mil. tonnes of straw is converted to the same amount of wood chips
Follow up on original agreement by March 22nd. 2000:The time limit for the fulfilment of the agreement is postponed to the end of 2005
Newest revision by march 29th. 2001 (New yearly capacity):ENERGI E2 (Eastern Denmark):
300.000 tonnes of wood pellets at the Avedøre, unit 2130.000 tonnes of straw pallets at the Amager, unit 2
ELSAM (Western Denmark):250.000 tonnes of straw200.000 tonnes of wood chips
