How standalone batteries work under the new rules
The framework permits households, businesses and industries to install energy storage systems that cannot export power to the grid. Users on dynamic tariffs can charge batteries when prices are lowest and discharge the stored energy when prices rise. The ministry presents this option as self-generation through storage for consumers who lack space or preference for solar panels. Inverter capacity may reach 100 percent of the agreed connection power. A dedicated sensor and remote-metering system prevent any grid feed-in. A bank guarantee scaled to inverter capacity is required except for low-voltage connections.
Simplified installation for balcony solar panels
Small plug-in photovoltaic systems no longer need a connection agreement, permit or fee. Consumers only notify the grid operator. Existing photovoltaic installations may add batteries without requesting extra electrical capacity when a common inverter is used. These steps reduce administrative barriers for small-scale self-consumption.
Faster grid connection procedures
Grid operators must reply to self-consumption connection requests within five days, down from 15 days previously. Specific deadlines now apply for any network upgrades needed to accommodate these systems. The shorter timelines aim to accelerate deployment of storage and solar for cost management.
Who benefits and how tariffs interact
Consumers with dynamic or orange tariffs gain the clearest advantage by shifting consumption away from high-price periods. Industrial and commercial users can also install larger standalone batteries to manage costs. The framework does not alter existing net-metering schemes but adds a parallel route focused on storage-only solutions.
Technical requirements and consumer obligations
Systems must include certified sensors that block reverse power flow. Remote metering enables real-time monitoring by the operator. The bank guarantee covers potential non-compliance costs and is waived only for low-voltage residential connections. These safeguards ensure the storage remains isolated from the public grid.
Frequently asked questions
Can batteries be installed without solar panels?
Yes. The framework explicitly allows standalone storage systems that charge from the grid during low-price periods and discharge later.
Do balcony solar systems still require permits?
No. Only notification to the grid operator is needed; connection agreements, permits and fees have been removed.
How quickly must the grid operator respond?
Response time is now limited to five days for self-consumption connection requests, with deadlines also set for required network upgrades.
Is a bank guarantee always required?
A guarantee linked to inverter capacity applies except for low-voltage connections, where it is waived.
Can batteries be added to existing solar installations?
Yes, provided a common inverter is used; no additional electrical capacity request is required.
