Two questions.
1) is it cheaper to produce electricity through wood burning power plant compared to conventional methods like, hydral, natural gas, coal? if yes or no, how cheap and expensive would it be comparitively?
2) Does it take more capital cost per MW of electricity to build the wood burning power plant and does it take 5, 10 times more space than say coal burning power plant?
For now coal is cheaper per Megawatt. It is cheaper per ton, greater availability, and has a higher heat value. With the greater availability of coal power plants are able to be bigger. If a power plant is bigger than its fuel supply than it ceases to be able to produce at full power, where it is most efficient.
Based on these facts coal plants can be built larger than wood or biomass plants. The construction cost per Mw goes down as the size of the power plant increases.
The amount of space depends on the delivery infrastructure. If you have a consistent delivery source and use the fuel as it is received than you don’t need as much land for fuel.
