A deadline nobody announced

There are sentences that never appear in site planning, because they sound like jurisdiction rather than electricity: “From winter 2026/2027, a first functional system of the power security platform will be available.” That is the timetable the Federal Network Agency (Bundesnetzagentur) has now made public, as reported by Energie & Management on 11 August 2026.

For a rental yard or a municipal depot, this sounds remote. It is remote – but not for the reason one might assume.

What the platform does – and what it explicitly does not do

The platform is not intended for normal grid operation. It is meant to apply when the federal government declares the emergency level under the Energy Security Act (EnSiG) and establishes the crisis case by statutory order. The EnSiG sets a high bar: the energy supply must be directly endangered or disrupted, and must not be securable in time by market-based measures, or only at disproportionate cost.

In a crisis, the agency could allocate scarce electricity by sovereign order and mandate consumption reductions. The platform itself performs no technical switching operations, the agency stresses; implementation remains with the addressees, and grid operators remain responsible for system security.

In short: a coordination channel is being built, not a switch.

Eight gigawatt-hours: the threshold below which nobody calls

All grid operators are to register, along with consumers using more than 8 gigawatt-hours per year at a single withdrawal point. Load reduction measures, according to the agency's documents, are aimed primarily at consumers from 10 gigawatt-hours upward, depending on the shortage situation. Planning data will only be requested once a shortage looks likely.

This is the point that matters for mid-sized businesses: the list in question starts at an order of magnitude that individual companies and construction sites never reach.

What that means for a site

Take the assumptions used in the cost comparison on this website: 70 percent load, six hours a day, 21 working days a month. That gives a daily demand of 10.5 kilowatt-hours. Across 252 working days a year, it comes to roughly 2.6 megawatt-hours – about three thousand times less than the 8 gigawatt-hours at which a withdrawal point is even registered.

*Arithmetic: 10.5 kWh × 252 = 2,646 kWh ≈ 2.6 MWh. 8 GWh = 8,000 MWh. 8,000 ÷ 2.6 ≈ 3,077.*

Two consequences, both uncomfortable:

1. A site supply will not be curtailed in a crisis because the site is on a list. It is on none.

2. The reverse holds too: nobody will call to ask whether the power is still needed. Prioritisation happens without the site.

Anyone working on a site where an outage means standing still gets no answer from this procedure. The answer has to exist beforehand – in the yard, not in the crisis.

The reserve that counts is measured

Storage is not a promise, it is a measured quantity. On the P25 that is 2.7 kWh usable, 2,500 W rated output and 5,000 W peak for at most ten seconds – enough for the inrush of a tool, not for continuous operation beyond rated output. Covering a 10.5 kWh day genuinely takes more: four units in parallel by calculation, or the remaining 7.8 kWh comes from the grid.

That number is uncomfortable, and it is the reason it appears here. A reserve that only lasts a full working day on paper is not a reserve in a crisis.
