In Hungary, the publication of hosting capacity by DSOs, such as MVM, is currently in a developing phase. While advanced smart metering and real-time grid monitoring are being gradually introduced, the existing practice relies on manual data processing and periodic publication. Hosting capacity information is made available in Excel format, typically upon request or when relevant grid developments occur. These datasets provide insights into available connection capacity at specific substations or network segments, helping stakeholders assess the feasibility of new distributed energy resource (DER) connections. Due to limited automation and digital infrastructure, capacity maps and interactive tools are not yet in use. The methodology behind these publications is aligned with EU regulatory requirements, focusing on transparency and non-discriminatory access. As digitalisation progresses, Hungary’s DSOs aim to enhance hosting capacity visibility through smarter systems and more frequent updates, supporting renewable integration and grid modernisation.
