TECHNICAL FIGURES

Technology specification (technical figures) Efficiency (heat, electrical, total) – main, well known Availability, reliability Level of automation Efficiency drop working at partial load Efficiency drop working at specific conditions Minimum achievable capacity

Wood chips boiler minimum achievable capacity is about 25 – 35% of nominal capacity. For electrical boilers starting from almost 0. Minimum achievable capacity Technology specification (technical figures)

Wood chips boiler. Nominal capacity 55 MW. Minimum about 15 MW Minimum achievable capacity Solution 1 Technology specification (technical figures)

Wood chips boiler. Nominal capacity 100 MW. Minimum about 25 MW Minimum achievable capacity Solution 2 Technology specification (technical figures)

Solution 1 in comparison with Solution 2 Lose Win Minimum achievable capacity Does additional production for Solution 2 justifies construction of 100 MW boiler instead of 55 MW? In this case it seems not Technology specification (technical figures)

If no hot tap water production exist (district heating network does not operate outside district heating season). Does additional production for Solution 2 justifies construction of 100 MW boiler instead of 55 MW? In this case it seems so Technology specification (technical figures) Minimum achievable capacity

Main types of costs

Fixed costs, €/MW Other variable costs, €/MWh Fuel, €/MWh X Production, MWh X Production, MWh / Efficiency X Capacity, MW Costs, €

MAINLY FIXED INCOMES, €/MW ENERGY SELLS Energy price, €/MWh x Volume/amount, MWh X Capacity, MW Incomes, € Example: reserve capacity

Economic and technical figures are important. Where to find them?

FINDING OF ECONOMIC AND TECHNICAL DATA IS NOT ALWAYS EASY WORK MAINLY IT IS NECESSARY TO CHECK AND COMPARE DIFFERENT SOURCES. DATA ACCURANCE STRONGLY AFFECT TO PLANNING RESULTS.
