The client plans to award the contract for heat energy demand simulation software. In addition to software licenses, the subject of the tender also includes software maintenance, operation and implementation.
The following brief description of the contract is for the sole purpose of informing the bidders, subject to change. For the bidding phase, the contract documents and other documents made available to the bidders in the course of the award procedure are decisive.
The Act on Heat Planning and Decarbonisation of Heating Networks, which is to be passed in 2023, aims to make a significant contribution to the conversion of the generation and provision of space heating, hot water and process heat to renewable energies and unavoidable waste heat and to a cost-efficient, sustainable, economical, affordable and greenhouse gas-neutral heat supply by 2045 (target year) at the latest, thereby Deliver final energy savings.
The share of heat from renewable energies or unavoidable waste heat in net heat generation in heating networks is to be at least 50 percent on average nationwide by January 1, 2030.
Heating networks are to be expanded in order to achieve the most cost-efficient climate-neutral heat supply possible, and the number of buildings connected to a heating network is to be increased significantly and dynamically.
The construction and operation of plants for the generation of heat from renewable energies, which is fed into a heating network, of necessary ancillary systems and of heating networks are in the overriding public interest (nature conservation, etc. must be taken into account).
These legal requirements (draft bill 07/2023, Act on Heat Planning and Decarbonisation of Heating Networks) thus have a massive impact on EWE NETZ GmbH's existing networks (in particular electricity and gas networks). The law explicitly requires that the operators of energy supply networks be involved in heat planning. Due to legal requirements, EWE NETZ will use publicly available and in-house data to carry out calculations with regard to heat energy requirements, which will be taken into account in target grid planning.
The required heat energy demand simulation software contains a large amount of basic data (e.g. census data for buildings) for the complete electricity and gas grid area of EWE NETZ GmbH and various possibilities to implement data sets. Based on these basic data, in-house data (e.g. energy consumption data) and simulation functions of the software, important and trend-setting insights can be gained with regard to grid expansion planning, so that investment funds can be used in a targeted and efficient manner (e.g. determination and presentation of the areas in which there will be an increased use of heat pumps that may require reinforcement of the power grid).
By means of the software, it is possible to keep the data sets that EWE NETZ must make available to the respective planning authority for the implementation of municipal heat planning.
The software can be used to carry out municipal heat planning for municipalities.
