The National Battery Research Institute (NBRI) successfully held Battery School 2026 on April 7–8, 2026, a two-day intensive training program themed Battery Energy Storage System for Residential and Industry. Participants came from PLN Batam, PLN Nusa Daya, PLN Enjineering, and PT Tokosen.

“Through Battery School 2026, NBRI aims to build the capacity of energy professionals to understand, integrate, and optimize BESS technology from residential applications all the way to industrial-scale grid systems.” – Prof. Dr. rer.nat. Evvy Kartini

Day 1: Building the Foundation
Prof. Dr. rer.nat. Evvy Kartini opened Day 1 with a foundational session on lithium-ion battery technology, guiding participants through battery components, working principles, performance metrics, and degradation mechanisms. Following that, David Adam Al Rosyid delivered an applied session on BESS applications for residential and industrial sectors, exploring key benefits, use cases, and operational considerations relevant to Indonesia’s energy landscape.

Hands-On Battery Pack Assembly
In the afternoon, a team of engineers (Muhammad Fakhrudin, Agus Sudjatno, Jesaya Hansel, and Azhar Basir) facilitated hands-on practical work on battery pack assembly. Participants worked directly on cell selection, pack configuration, Battery Management System (BMS) integration, and safe assembly practices.

Day 2: Systems, Integration, and Industry Insights
Day 2 opened with a deeper introduction to BESS architecture by Prof. Dr. rer.nat. Evvy Kartini, covering system components, applications, and industry trends in Indonesia. Participants then engaged in a practical session on BESS Application and Grid Integration, performing grid simulations, operating BESS systems, and addressing technical issues in real scenarios.

During the afternoon practical session, participants went beyond simulation, conducting a direct real-world test of BESS energy storage capacity by charging the system using solar panels under live sunlight exposure. This field trial gave participants firsthand experience of how solar energy can be integrated with BESS in actual operating conditions.

Business, Testing, and Safety Sessions
Muhammad Firmansyah, S.E., M.B.A., then led a business-focused session outlining BESS market trends and investment opportunities in Indonesia. Following that, Rachmad Hidayat from PT Hioki Electric Indonesia and Respati Biwara Wicaksana from Quantel Chroma Indonesia jointly presented a session on Testing and Measurement of BESS Applications for Residential and Industrial use, delivering in-depth insights into testing standards and measurement methodologies for real-world BESS deployment.

Ricky Herlambang, S.T, subsequently walked participants through Battery Pack Safety Testing under the SNI 8872 standard, including a direct laboratory demonstration visit. Prof. Dr. rer.nat. Evvy Kartini then closed the program with a Project Discussion, where participants demonstrated their integrated understanding of BESS through evaluation and applied discussion.

NBRI Recognizes the Top Three Participants
At the closing ceremony, NBRI announced the three best participants of Battery School 2026 honoring individuals who demonstrated outstanding performance across both theoretical and practical sessions. First place was awarded to Ramadhan Yusuf JR from PT PLN Batam, followed by Indah Purnama Sari from PT PLN Batam in second place, and Roni Karua from PT PLN Nusa Daya in third place.

NBRI Commitment

Battery School 2026 reflects NBRI’s ongoing commitment to advancing Indonesia’s battery ecosystem through education, research, and industry collaboration. As the country accelerates its energy transition agenda, structured programs like Battery School are positioned to play a critical role in producing a generation of BESS-ready professionals capable of deploying clean energy solutions at scale.
