Grid Fees 2027: Why Peak Demand is Becoming the New Lever for Energy Costs
For years, the calculation was simple: those who draw fewer kilowatt-hours from the grid pay lower grid fees. Starting in 2027, this perspective will no longer be sufficient in Austria. With the new tariff system, the focus shifts to when and with what level of demand electricity is drawn. Almost simultaneously, the federal government is linking PV subsidies to intelligent storage control. These are two decisions from October 2026 that point in the same direction—and have consequences for grid operators, energy suppliers, energy communities, and plant operators alike.
What is changing regarding grid fees starting in 2027?
On October 29, 2026, E-Control published the consultation draft of the System Utilization Fee Tariff Ordinance 2027. It translates the framework ordinance, which was already consulted on in the summer, into specific tariffs. Comments can be submitted until November 20, 2026; therefore, the published values are still preliminary. The core of the reform: In the future, the grid fee for households and small commercial customers at grid level 7 will no longer consist almost exclusively of a consumption price per kilowatt-hour, but will additionally include a demand charge. In the long term, both components are intended to account for approximately half of the fee each. The transition will take place in stages.
For an average household, E-Control preliminarily calculates approximately 5.7% lower grid fees under the new system. This figure is an Austrian average. How the bill actually changes depends on the grid area, consumption, and, above all, the individual peak demand.
What does this mean for the day-to-day operations of energy companies?
For grid operators, the work begins with the consultation process: the start date for their own grid area must be justified to E-Control, and billing, customer communication, and data processes must be able to process monthly demand values.
Frequently Asked Questions about Grid Fees and Demand Charges
When does the demand charge for households in Austria take effect?
Each grid operator determines the timing for its own grid area, specifically between January 1, 2027, and July 1, 2028, at the latest. From this date, the demand charge applies to all grid customers at grid level 7. The specific tariff values for 2027 are under review until November 20, 2026.
How is the peak demand measured for the grid fee?
The decisive factor is the highest 15-minute demand value of a calendar month, measured via the smart meter. This peak counts even if it occurs only once a month. A minimum of 2 kW is billed. A lower rate is provided for demand up to 10 kW than for the portion exceeding it.
Will PV subsidies in Austria be completely eliminated starting in 2027?
Classic investment subsidies for small PV systems are to be phased out. They will be replaced by a storage system bonus for storage in new systems and for retrofitting existing systems, combined with the requirement for an intelligent energy management system. Innovative PV, such as building-integrated systems or Agri-PV, remains eligible for funding. The subsidy amount and criteria have not yet been decided.
What does grid-supportive operation of a storage system mean?
A grid-supportive storage system does not just charge and discharge according to its own consumption, but aligns itself with the needs of the grid and the overall system—for example, by absorbing PV surpluses at midday and shaving the peak demand in the evening. The exact technical criteria for this are currently being developed by the Ministry together with the industry.
