Even though biomass is an important renewable source in the EU, its promotion should be careful in Bulgaria: low-income households are often compelled to purchase cheap, humid wood and low-quality coal, before burning them in highly inefficient stoves. This becomes the primary cause of dramatic seasonal increases in air pollution in their communities. The link between energy poverty and poor air quality has now started to gain recognition: grants for replacing old heating equipment are already in place.
In the city of Plovdiv, around 18,000 households are heated with firewood and coal, producing 539 tonnes of particulate matter (a measure of air pollution) and 52,000 tonnes of CO2. The Energy Agency of Plovdiv supports the Municipality of Plovdiv in implementing a heating replacement programme, providing a 100% state grant for 3,500 households to replace their old heating stoves with environmentally-friendly alternatives. This action aims for an estimated 20% reduction in polluting emissions.
The Energy Agency of Plovdiv (EAP) provides technical support to household applicants through on-site home visits, energy and heating diagnostics, professional expertise about what alternative heating device to choose, follow-up, and quality control over the installation of new devices. EAP mediates the heating replacement process between the local authority, the energy technology provider, and the households through live and platform-based communication. It calculates the potential for post-intervention energy and emission savings and supports the promotional campaign for heating replacement.
