Something goes wrong with the calculation of the depreciation costs of hybrid heat pumps. The depreciation costs are too (factor 2?) high.
Details
To make it clear I made the following LES. It contains 5 end nodes. Each contains 1 buffer with 100 units and demand 1000 kWh and 1 heating technologies. Every technology has investment costs of 1000 euro, O&M costs 100 euro/year and a lifetime of 20 years.
The stakeholders assigned to node 1 to 5 are AC1, AC2, AC3, etc.
Node 1 and 2 contain hybrid heat pumps for respectively space and water heating. The other nodes contain other heating technologies.
The depreciation costs should be:
100 units (1000 investment costs / 20 years lifetime + 100 O&M costs/year) = 15,000 euro.
This is the case for stakeholder AC3, AC4 and AC5.
However, the depreciation costs for stakeholder AC1 and AC2 are 30,000 euro.
