INSIGHTS FOR PROPERTY OWNERS
Well informed. Make focused decisions.
Guidance for your property: building renovation and financing, EV charging and grants, and developments in tenant electricity and neighbourhood energy supply.
Editorial review: 24 October 2026 · Research period: 26 September–24 October 2026
27 October 2026 · Germany
Application deadline: 10 November 2026
The federal programme for charging infrastructure at existing apartment buildings currently accepts applications from owners’ associations, SMEs and private landlords until 10 November 2026, subject to available funds. The call for companies with large housing portfolios has closed.
Illustrative calculation: ten eligible spaces with wallboxes × €1,500 gives up to €15,000 in grants. Assuming total costs of €50,000 leaves €35,000. Costs are a hypothetical example; eligibility and actual prices require confirmation. Missing the deadline means this funding opportunity cannot be used in the current call.
We structure the assessment of the building, parking spaces, installation scope and grant conditions, and coordinate suitable specialist partners where needed. The project administrator decides on grants. An enquiry or order alone does not secure funding.

Building envelope, energy rating and KfW finance.
Understand statutory U-values, renovation sequences and the difference between an energy rating and an efficiency-house standard. Includes the July 2026 legislation and financing examples. German programmes and law apply.
A better energy-certificate rating alone does not qualify a building for KfW 261. The proven efficiency-house standard, eligible costs and lending approval determine the outcome. Grants with a supplementary loan can be an alternative for individual measures.
Read the renovation and financing guide →MiSpeL: new rules for storage and bidirectional charging
On 1 October 2026, the Bundesnetzagentur revised the market integration of electricity storage and charging points. The decision provides a separation option and a flat-rate option for determining the respective electricity quantities.
Adopted, with conditions for use
Until the end of September 2027, early use of either option requires the consent of the grid operator and metering operator. The flat-rate option also depends on state-aid approval of its statutory basis.
What this means for owners
For projects combining solar PV, storage and bidirectional charging, the metering concept and operating model should be assessed together. This is not automatic approval for every existing wallbox.

Feed-in remuneration from 2027: what does it mean for tenant electricity?
The proposed EEG 2027 reform envisages a shift from fixed feed-in tariffs towards more direct marketing, with transitional provisions for new installations below 25 kW. This does not establish a blanket end to all remuneration on 1 January 2027.
Planning status
The cabinet proposal and parliamentary consideration are officially documented. Our research has not established a final promulgated act for this reform. The start on 1 January 2027 remains proposed; final rules and transitional periods must be checked before investment.
Separate tenant supply from grid exports
Tenant electricity supplies part of the solar output directly to residents; surplus goes to the public grid. Under current law, qualifying direct supplies may receive the Mieterstromzuschlag. Support for surplus exports is separate. Changes to feed-in remuneration do not automatically end tenant electricity or its supplement.
How we assess your project
If grid-export revenue falls or becomes more variable, consumption within the building may become relatively more important. This is an economic interpretation, not a return guarantee. Consumption, tenant participation, electricity prices, investment, metering, billing and residual electricity costs remain decisive.
We compare local use and exports across scenarios. Existing installations and new projects are assessed separately; new-installation changes are not automatically applied to existing entitlements. We do not simply carry 2026 subsidy rates forward into 2027.

Sharing solar electricity across buildings
Energy sharing allows jointly using renewable electricity through the public distribution network, linking generation and consumption in different buildings. It can suit neighbourhoods, but is not a blanket simplification for every district supply model.
What has applied since the summer?
The law entered into force in December 2025. Since 1 June 2026, grid operators must enable sharing within their balancing area. From 1 June 2028, this extends to directly adjacent balancing areas in the same control area.
Bundesnetzagentur notice No. 73 of 7 July 2026 explains implementation within existing supplier and balancing-group arrangements. Suitable suppliers or service providers handle the energy-market processes.
What implementation requires
Appropriate contracts, quarter-hourly metering and allocation, and supplementary residual supply are required. Operator and participant eligibility needs individual checking. Participants retain free choice of their residual electricity supplier.
How it differs from tenant electricity
Energy sharing uses the public grid, unlike local direct supply and shared building supply. According to Bundesnetzagentur guidance, fixed EEG feed-in tariffs are excluded for sharing installations, which are assigned to direct marketing. A market premium requires the relevant eligibility conditions.
Whether sharing is more economical than building-based tenant electricity depends on consumption, grid charges, metering and administration. Using the public grid does not automatically make it cheaper. This background article concerns summer 2026 and is not a new decision within the four-week research period.

Solar electricity in apartment buildings
Clarify whether electricity will serve the building, heat pump or tenants. Roof, consumption and the operating model belong in one assessment.

Consumption, current heating and heat emitters provide the starting point. The initial check structures this information for further planning.

Review parking spaces, initial charging demand and available power. The check provides initial guidance and identifies questions for assessment.
