The German energy company EWH visited the UBBSLA pilot site
In order to familiarize themselves with, study and transfer the results of the pilot activities under the ESINERGY project, a number of bilateral visits to the partner organizations at the transnational level are planned.
In the implementation of this activity, the UBBSLA team welcomed two experts from the German energy company Elektrizitätswerk Hindelang eG (EWH) to Bulgaria. On 14.03.2025, in order to exchange experience, they visited the municipality of Beloslav and the pilot model that UBBSLA implemented in one of the buildings of the first Bulgarian glass factory. Today, a large part of the factory is a museum with exhibition and demonstration halls of the production process of glass products, which is visited annually by over 8,000 children for educational purposes. A photovoltaic installation is installed on the roof of the factory, which generates electricity. Like any similar installation, the generation of electricity depends on many factors such as – solar radiation, temperature, dustiness, etc. The pilot investment under the ESINERGY project is a “battery system for intelligent energy management and storage”, and experts are currently testing the system’s processes to manage energy generation and consumption through this local battery station.
During the exchange visit to Beloslav, Eng. Tonev (UBBSLA) shared that “the goal is to increase the share of renewable energy sources through energy storage options in a battery system and to increase the company’s resilience to changes in the electricity system and to reduce electricity costs accordingly.” For his part, the German expert ANDREAS KLӒR (EWH) summarized that “what we saw in the pilot model of the UBBSLA is really interesting for us and in general we think it is important to test this pilot activity because in the future, through a greater penetration of renewable energy sources and in particular photovoltaic systems in the energy grid, we will see a greater difference between prices during the day and evening hours. In Bulgaria, companies already have dynamic price levels and therefore it will be really important to either shift loads and consumption or store energy in battery systems in order to have cheap electricity from noon to evening.”
In addition to the technical characteristics of the system being tested, the UBBSLA experts on the project are reviewing the legislation and directives in order to propose various changes to the regulations and the energy efficiency law, so as to facilitate the procedure and offer more economic opportunities with a return on investment.
