Kyiv Apartment Complex Gains 15-Hour Backup Power Through Solar and Battery Upgrade

Three residential buildings in Kyiv can now keep their essential systems running during grid outages, following a comprehensive energy upgrade that combines solar generation with battery storage.

The complex, which spans more than 30,000 square metres, is equipped to operate elevators, heating substations and common-area lighting independently for at least 15 consecutive hours. The installation includes 108 solar panels, three inverters, a 135 kWh battery bank and a 9 kW backup generator. Three individual heat substations were also installed, delivering more even heat distribution and cutting the buildings’ heating consumption by at least 20 per cent.

The retrofit went beyond energy systems: all six elevators were replaced, windows and doors were renewed, internal utilities were overhauled, and motion-sensor lighting was fitted in shared spaces. Mayor Vitaly Klitschko noted that the project combined on-site generation, battery storage and energy-efficient technologies to achieve the result.

Roughly 70 per cent of the total cost was covered by municipal funds or grants under state programmes. The homeowners association now plans to seek additional support through the city’s 70/30 co-financing scheme for façade insulation, and to tap a revolving credit fund for the next phase of works.
