Cost Comparison

Cost Comparison

The graph below shows a comparison of fuel, maintenance and operation and CO2 emission costs from the project and reference scenarios.

Cost comparison

The project scenario clearly has an advantage of lower annual costs than the reference scenario, but this is necessary since it also requires a significant up-front investment.

If we sum all the avoided costs and count them as savings relative to the reference scenario, we can generate an initial investment followed by a stream of increased income.

The image below gives the annual saved costs (Total reference scenario heating costs - Total project scenario heating costs) over time as a stream of income relative to the initial investement.
