Under the draft of 6 August 2026, low-voltage connections up to 100,000 kWh keep a standing charge and an energy charge; those generating behind the connection pay a prosumer surcharge of 70 to 90 percent of the standing charge, plug-in solar devices excepted. Above that, and above low voltage, a capacity price applies, and generation plants above 30 kW pay a feed-in charge. The draft provides dynamic grid charges only for storage (2030 at the earliest, 2033 at the latest) and generation (2032 to 2035), not for final customers for now. Follow-up rulings in 2027, effect from 2029.

If the deadline is missed: No direct legal consequence The date is the Federal Network Agency's. Its notification, set for 1 January 2027 in the draft (operative point 20), starts other cut-offs, such as grandfathering for storage and generation plants with an investment decision before notification, to be proven to the network operator by 31 March 2027.

According to its press release, the Bundesnetzagentur collects progress twice a year, and it has been running supervisory proceedings against laggards since March 2026.

Law · adopted

If the deadline is missed: Regulator can enforce If the default metering point operator misses the quota, the Federal Network Agency can order measures under Sections 45(2) and 76 MsbG and enforce them with coercive fines of EUR 1,000 to EUR 10 million (Section 76(4) MsbG, Section 94 EnWG).

If the deadline is missed: Regulator can enforce The Heat Planning Act sets neither a fine nor a specific power to issue orders for a missing or late roadmap. Compliance is monitored by the authority each federal state designates under Section 33(5) WPG. Legal basis ↗

Applicability: Heat networks already fed entirely by renewable heat, unavoidable waste heat or a combination of both are outside the duty, as are networks under 1 km and networks with an approved BEW transformation plan. The pending WPG amendment would give only operators of industrial heat networks until the end of 2030.

By the end of 2026 default metering point operators must have equipped at least 90 percent of the generation capacity up to 100 kilowatts that came online between 25 February 2025 and 30 September 2026. The yardstick is installed capacity, not the number of metering points.

Law · adopted

If the deadline is missed: Regulator can enforce If the default metering point operator misses the quota, the Federal Network Agency can order measures under Sections 45(2) and 76 MsbG and enforce them with coercive fines of EUR 1,000 to EUR 10 million (Section 76(4) MsbG, Section 94 EnWG). If the equipping of installations with control units falls short by at least 25 percent and this contributes significantly to a possible threat to system security, it can withdraw the default responsibility under Section 12(2g) EnWG. Legal basis ↗

Applicability: Under the government draft for EEG 2027, the installation quotas in Section 45 MsbG would count metering points to be equipped instead of kilowatts, with the default metering point operator free to choose for this quota at 31 December 2026. Nothing has been adopted.

CHP Act support requires that CHP plants start commercial operation by 31 December 2026, or hold a federal immission control permit or binding order by then and start commercial operation within four years. Support for heat networks and heat storage is also tied to 31 December 2026 (commissioning or all permits under state law in place).

Law · adopted

If the deadline is missed: Money is lost The CHP premium under Section 6(1) sentence 1 no. 1 KWKG is only paid if the plant enters commercial operation by 31 December 2026, or holds an immission control permit or binding order by then and starts commercial operation within four years; awards from CHP tenders are exempt. Similar cut-offs apply to new heat networks and heat storage (Section 18(1) no. 1 and Section 22(1) no. 1 KWKG). Legal basis ↗

The right to a grid connection no longer covers the maximum generation output: for plants connected from 1 January 2027, the draft caps feed-in from new first-segment solar plants at 70 percent of installed capacity and from onshore wind at 280 watts per square metre of rotor area (Section 8 of the draft EEG). By then the transmission system operators submit procedure rules with prioritisation criteria to the Federal Network Agency, and distribution system operators may adopt them. Grid operators show available capacity on grid maps every month; the electronic enquiry procedure from 135 kilowatts only arrives in 2028 under the draft.

If the deadline is missed: Regulator can enforce Under the government bill (Bundestag printed paper 21/7866) the new duties carry no fine of their own. Duties such as the transmission system operators' submission of procedure rules or the monthly capacity map (Sections 17a and 17c of the draft EnWG) could be enforced by the regulator under Section 65 EnWG.

Under the government draft, subject to the Bundestag's decision and EU state aid approval: new PV systems below 25 kW receive a temporary transition payment from the grid operator for at most 36 months instead of the feed-in tariff, then direct marketing with a 1.5 ct/kWh bonus for up to 48 months. Rooftop systems below 100 kW cap feed-in at 50 percent permanently. Systems commissioned by 31 December 2026 stay under the old rules. In the MsbG, mandatory smart meters and control devices for generation start above 2 kW, and the installation quotas in Section 45 count metering points instead of kilowatts. The Bundesrat wants to drop the 2 kW threshold; the federal government rejects that.

If the deadline is missed: No direct legal consequence Under the draft (Bundestag printed paper 21/7867), payment obligations for breaches under Section 52 EEG fall on plant operators; it sets no separate sanction for network operators, metering point operators or suppliers. According to the explanatory memorandum, network operators need software to administer the temporary transition payment. Legal basis ↗

Applicability: Under the draft this only affects new systems commissioned from 1 January 2027. Existing systems stay under the old rules; plug-in solar devices up to 2 kW are exempt.

Gateway administrators have their GWA system assessed against version 2.0 at the next certification or recertification from 1 January 2027. Version 2.0 covers remote workplaces, cloud service providers, zero trust, time servers and penetration tests, among other things. Version 1.0 stays valid until 31 December 2028.

If the deadline is missed: Exclusion or loss of role Conformity with TR-03109-6 is proven by certification. If the default metering point operator lacks the certificates required under Section 25 MsbG, the fallback metering operator takes over in emergency operation (Section 11(2) no. 2 MsbG) and, six months later, the default responsibility (Section 11(4) MsbG).

Anyone certifying a smart meter gateway against version 2.0 of the protection profile and TR-03109-1 must also prove the MUSS+ requirements from 1 January 2027. According to the BSI these include a WAN API, registering power metering over the local metrological network and factory reset by the service technician, plus TAF 8 in its new form and TAF 15. By mid-October 2026 no gateway had been certified under version 2.0.

Regulatory ruling · adopted

If the deadline is missed: Exclusion or loss of role Without MUSS+ proof there is no version 2.0 certificate from that date. Without a valid certificate, a smart meter gateway may not be used as part of a smart metering system under Section 24(4) MsbG, and under Section 25(1) MsbG the gateway administrator may only use gateways with valid certificates.
