Sources, selection and units
Solar PV: Our own query of the Federal Network Agency’s Marktstammdatenregister (MaStR): municipality “Ulm”, energy source “Solare Strahlungsenergie” (solar radiation), status “In Betrieb” (in operation). Data as at 29 October 2026, 00:00: 7,830 units and 140,753 kW gross rated power, rounded to 140.8 MWp. The PV system count refers to registered PV units. Several entries may belong to the same installation or location; the count does not represent roofs or households. MWp describes installed power, not annual electricity generation.
Battery storage: Municipality “Ulm”, storage technology “Batterie” (battery), status “In Betrieb” (in operation); the same registry snapshot. A total of 3,315 storage units with 29,379 kWh of usable capacity, rounded to 29.4 MWh. This includes the registered size categories within that selection. One unit does not necessarily represent one household. Capacity in kWh is different from power in kW.
Charge points: Our own analysis of the Federal Network Agency’s charging station register, dated 30 September 2026, for Ulm urban district, status “In Betrieb” (in operation). The count refers to charge points, not locations or charging stations. Source: Bundesnetzagentur.de, CC BY 4.0. Understand charging locations and data.
District heating: Heat input to the FUG network in 2024/2025: 691,943 MWh, rounded to 691.9 GWh; company figures checked on 6 October 2026. The scope is the FUG network. This figure represents neither the city’s total heat demand nor the heat delivered to households. Network losses occur between input and delivery.
A snapshot: The Ulm registry figures include neither Neu-Ulm nor the Alb-Donau district. Late registrations and corrections can change the registry totals; the most recent additions may not yet be fully recorded. Counts, power, capacity and annual energy are different quantities and are not combined here into an overall total or a climate balance.

Electricity + heating + mobility
One home. Several projects.
A solar roof, an electric car and heating influence one another. If you are planning several changes, consider electricity demand, usage times and work on the building that could be combined.
