On 19 February 2026, Government Decree 28/2026 (II. 19.) was promulgated, introducing an important amendment to the implementing regulation of the electricity (Government Decree 273/2007 (X. 19.) – hereinafter: “Implementing Decree”). The purpose of the amendment is to ensure that inverter replacements carried out in connection with the Home Energy Storage Programme („Otthoni Energiatároló Program”), launched in 2025 and announced for 2026, do not result in unfavourable settlement consequences for operators of household-sized small power plants.
The Home Energy Storage Programme is a state aid scheme designed to promote the installation of battery energy storage systems connected to residential photovoltaic systems. Within the framework of the programme, households may apply for non-repayable grants, subject to specified conditions, for the establishment of energy storage systems.
In this article, we present the essence and practical relevance of the legislative amendment, as well as the legal framework within which inverter replacements and settlement-related issues must be assessed.
