Economic feasibility of solar heat for large consumers

Economic feasibility (profitability) is defined as the maximum allowed price minus transport costs and cost of heat from the relevant source. To determine the economic feasibility of heat sources in combination with heat demand, a number of assumptions have been made in terms of investments for the decoupling of heat from each of the sources. All euros are annually; investments shall be made annually and net in cash with the following parameters: • Area-related network investments: efficiency requirement is 8 %, duration of 30 years • Investment and transport network (from heat source to areas/clusters): return requirement is 12 %, term 30 years. The efficiency requirement here is higher because of a higher risk of low heat disposal at the beginning of the project (it often happens that not all homes are connected to the transport pipeline at the beginning). • Heat sources investments: return requirement 8 %, term 15 years For the municipality of Vijfheerenlanden, which has been part of the province of Utrecht since 1 January 2019, no data is yet available.
