Transformation plan BEW

In addition to feasibility studies for new networks, we also support operators of existing networks in creating a transformation plan. With our heatbeat Digital Twin we create a Digital Twin of your existing network which realistically represents the dynamic behavior of the network. With this foundation, we evaluate the effectiveness of various potential measures to decarbonize the district heating network and identify an optimal transformation path. We support you in working out the most economical path for a future-proof and sustainable operation of your network.

The process is designed to the requirements of the 'Bundesförderung effizienter Wärmenetze' (a federal funding for efficient heat networks, abbreviated 'BEW'). We had already summarized the current status for you in our newsletter . And since the BEW came into effect on Sept. 15, 2022, we look forward to discussing funding opportunities with you and supporting you from start to finish. In issue 15 of our newsletter, we had summarized these requirements:

Transformation plans must outline the temporal, technical and economic conversion of existing district heating networks until 2045. The goal is to show how the existing district heating network can be operated with renewable heat sources by 2045. The complete transformation plan contains an analysis of the existing heat network system's current state. From this current state analysis, scenarios are developed for the specific transformation of the network. These include, for example, the identification of potential renewable energy sources and waste heat, as well as demand scenarios (e.g., refurbishment, retrofitting, and expansion) up to the year 2045. Building on these scenarios, the heat generator portfolio, including the integration of storage systems, must be presented. The share of biomass in the annual heat is limited depending on the network length. In particular, the phase-out of fossil fuels in heat generation by 2045 needs to be investigated. The complete transformation plan also includes the necessary hydraulic parameters (temperature, pressure, volume flows, etc.) of the district heating network and measures for network optimization (e.g. measures in the buildings and for temperature reduction). All results must be documented in a detailed description of the transformation plan.
