The project of “STARTER LM-21” LTD aims to sustainably reduce energy costs and strengthen the company’s competitiveness in retail and repair of starters and auto-electrical components (NACE 45.32). The site is located at 15 Zelendolsko Shose St., Blagoevgrad, hosting diagnostics, repair and testing of starters/alternators, as well as storage and retail operations—activities with continuous electricity demand for test benches, compressors, lighting, ICT equipment, and for space heating/cooling of work areas. The investment foresees a high-efficiency 50 kW water-to-water heat pump for HVAC, integrated with low-temperature indoor units (e.g., fan coils) and governed by smart automation for optimal load and comfort. In parallel, a 45 kW rooftop photovoltaic plant with battery storage will be installed, interconnected via hybrid inverters and an Energy Management System (EMS). The batteries will increase self-consumption of on-site generation, shift peak loads, and provide backup for critical consumers (diagnostic benches, IT, lighting) during grid disturbances. The project covers supply, installation and commissioning of equipment, deployment of monitoring systems and metering of energy performance, EMS software, staff training, and information & publicity measures. Expected outcomes include a substantial reduction of grid-purchased energy, lower operating expenses, a higher share of renewables in the energy mix, and reduced greenhouse-gas emissions. Implementation will stabilize operational processes, improve the working environment, and support the company’s sustainable growth. The proposal fully aligns with the procedure’s goals on energy efficiency and renewable energy use in enterprises, integrating state-of-the-art technologies, digital control, and measurable resource-efficiency gains.
