Powerful New Battery System Keeps Mariupol Lyceum Running During Blackouts
60 kWh storage ensures light for children. The Mariupol Lyceum in Pushcha-Vodytsia near Kyiv is now powered by a new hybrid solar and battery system, ensuring electricity even during blackouts caused by attacks on Ukraine’s energy grid.
Thanks to the support of BILD hilft e.V. “Ein Herz für Kinder”, the school received a stationary battery system with a capacity of 60 kWh, combined with a 20 kW solar panels.
This powerful setup keeps the most important facilities running: lighting, servers and the kitchen, which provides hot meals to children who live and study here.
During outages, the system allows the school to operate autonomously for up to six hours, ensuring safety, warmth, and comfort for students and teachers.
The Mariupol Lyceum was once a leading science-focused school in Mariupol. After the Russian occupation in 2022, it was evacuated to Kyiv, where it continues its mission in exile. Many of its students and teachers are displaced, some of them more than once. About 150 children study offline and 90 online, and for dozens of them, the school has also become a temporary home.
For these children, electricity means the ability to study, eat, stay warm, and feel safe.
Our dog is a double refugee, she fled with us from Luhansk,” says Anna, one of the students.
In 2014, Anna’s family evacuated from Luhansk to Mariupol, and in 2022, they had to flee again, this time to Kyiv, after Mariupol was occupied and destroyed.
Anna now lives at the Lyceum together with other displaced children. “Before, when there were power cuts, the school sometimes used a generator,” she adds. “But now, with the new system, we’ll always have electricity.”
The hybrid system includes eleven battery units of 5 kWh each, a Battery Management System (BMS), sensors for temperature and humidity, and a fire-suppression and climate control system to ensure safe operation. The panels are oriented east–west to maximize energy generation throughout the day. Ukraine2Power designed the system to be expandable: additional solar panels can be added later, increasing self-sufficiency and cutting energy costs.
Even on October 10, 2025, when missile attacks left much of Kyiv in darkness, the Lyceum stayed brightly lit.
During the opening, Ukraine2Power held an interactive session on renewable energy for 70 students. They learned how sunlight is converted into electricity and how clean energy benefits people and the planet. Ukraine2Power also organized a small quiz and competition about renewable energy. The students participated with great enthusiasm, answering questions, sharing what they had learned, and winning small prizes for their active engagement. Students later created thank-you cards in German for the donor organization, heartfelt messages from children who finally have light again.
We sincerely thank BILD hilft e.V. “Ein Herz für Kinder” for making this project possible – for believing in the power of education, in the strength of Ukrainian children, and in sustainable solutions that bring light where it’s needed most.
We also thank our partner organization Smart Osvita, for their cooperation and support in developing the technical solution.
