Sistem Emergency Power Supply (EPS) berperan penting dalam menjaga kontinuitas operasional gedung penyiaran televisi, khususnya Gedung Operasional TVRI Jawa Tengah. Penelitian ini bertujuan mengevaluasi kondisi operasional sistem EPS, tingkat pembebanan tiap unit UPS, serta keandalan komponen berdasarkan histori gangguan dan pemeliharaan. Penelitian dilakukan dengan pendekatan studi kasus kuantitatif deskriptif menggunakan data primer (observasi dan wawancara) serta data sekunder (data operasional, histori gangguan dan pemeliharaan periode Mei 2023-Mei 2026), yang dianalisis melalui persentase pembebanan UPS dan parameter keandalan Mean Time Between Failure (MTBF), Mean Time To Repair (MTTR), Availability, dan Reliability. Hasil penelitian menunjukkan bahwa sistem EPS yang terdiri atas empat unit UPS online terdistribusi, satu genset utama, dan satu genset redundan secara umum mampu mempertahankan kontinuitas suplai daya pada beban kritis. UPS 1 mengalami kondisi overload (111,41%) saat beban puncak dengan histori gangguan terbanyak, sedangkan UPS 2,3, dan 4 masih berada dalam batas kapasitas dengan availability di atas 99,99%. Genset utama dan genset redundan juga menunjukkan keandalan tinggi, meskipun perpindahan ke genset redundan masih memerlukan intervensi operator. Secara keseluruhan, konfigurasi sistem EPS dinilai andal, namun penambahan kapasitas UPS 1 dan perluasan cakupan perlindungan UPS diperlukan untuk meningkatkan keandalan sistem.
