The energy transition in Germany and Europe requires massive investments in infrastructure – particularly in heating and electricity distribution networks. Municipal utilities are at the heart of this implementation. This opens up attractive opportunities for institutional investors to participate in long-term, secure, and socially relevant infrastructure projects – without having to assume operational responsibility.
According to a report by Prognos AG commissioned by AGFW and VKU, the investment requirement in district heating infrastructure will amount to around €74.4 billion by 2045. These funds are needed for the expansion of heating networks and the decarbonization of generation through the use of renewable heat sources such as deep geothermal energy, industrial waste heat, and large heat pumps, as well as the construction of heat storage facilities.
At the same time, the electricity distribution grids must be massively expanded and modernized to enable the integration of decentralized generators, charging infrastructure, and heat pumps. In Germany, the electricity grid infrastructure is organized on two levels: distribution grids are mainly operated by municipal utilities and energy suppliers, while transmission grids are organized by national Transmission System Operators: 50Hertz, Amprion, TenneT, and TransnetBW. The electricity grids are regulated by the state and are reliably refinanced via grid fees, which must be approved by the “Bundesnetzagentur”. The investment required in the distribution grids is estimated at €323 billion by 2045 – almost on a par with the transmission grids (€328 billion).
This article deliberately focuses on the municipal side of the energy transition, i.e., on investments that are not regulated by the state but can be made in a cooperative and market-oriented manner.
Investments in municipal heating and electricity distribution networks generally meet all the requirements of the EU taxonomy and are considered ESG-compliant. They contribute directly to decarbonization, social participation, and security of supply. The investment objects – such as heating networks, storage facilities, or transformers – are usable in the long term, technologically proven, and socially accepted.
Most municipal utilities in Germany are owned by the public sector and therefore generally have a good credit rating. At the same time, they bring decades of experience in operating critical infrastructure and are deeply rooted in their regions. They know the local conditions, have qualified personnel, and are able to plan and implement complex projects independently.
A current example of successful cooperation is the project of Stadtwerke Konstanz, which will realize the expansion of its district heating network together with a private financing partner. A project company was founded with the company Iqony Energies GmbH, which is to realize the first heating network in Konstanz – based on regenerative environmental heat from Lake Constance. Stadtwerke is responsible for the technical implementation and operation, while the investor takes a passive role and participates in the stable returns via a balanced, structured financing model.
Institutional investors do not have to assume operational responsibility. The municipal utilities have the necessary know-how to implement projects operationally. Investors can score points with long-term stable returns, high social relevance, and a contribution to decarbonization.
