The German energy market is unusual in one important respect: it is defined almost entirely by regulation. The direction of travel is set by the energy transition, but the timing and the mechanics are set by legislation, which means a company's products can change because a law changed, not because a customer did.
Florian Müller, Managing Director of Energy Market Solutions and a subsidiary of a municipal utility (Stadtwerke) himself, describes what that looks like in practice. The recent EEG reform removes feed-in payments for small installations, which instantly creates a market for someone to sell that power instead. A ruling on the market integration of storage and charging infrastructure arrives in October 2027 and will reshape market processes again.
On the demand side, progress is slower than the headlines suggest. Generation has shifted: most German electricity is now renewable, and prices move with wind and solar. But flexibility in the mass market is barely beginning. Smart meter rollout stands at roughly 25 percent, meaning three quarters of the potential is not yet technically accessible. The price signals exist: around 800 hours of zero or negative prices this year, rising by half annually, alongside spikes of 700 euros per megawatt hour. What's missing is the infrastructure to respond to them, and a regulatory framework that structurally lags the situation.
For municipal utilities, this compounds an already difficult position. Heat planning, smart metering, dynamic tariffs, all at once, and most cannot do everything simultaneously. Florian is direct about why focus is so hard: the strengths that define a Stadtwerk are stability and taking responsibility. Deliberately handing responsibility to a partner, or exiting a business line entirely, cuts against that identity.
His conclusion lands on something Centida sees constantly. Without a clear view of which business areas require what investment and return what earnings, none of these decisions can be made deliberately. They get made under pressure instead.
