How to Get Started with Certification
Steps to Enroll in Certification Programs
Getting certified is a crucial step toward building a safe and successful career in battery storage. Start by identifying the associate-level certification that fits your current experience. If you’re new to the field, focus on Associate Credentials rather than advanced certifications like the Energy Storage Installation Professional (ESIP). The associate-level path is tailored for beginners who may not yet have hands-on experience in the industry.
To get started, review the NABCEP Certification Handbook for a full breakdown of the requirements. Then, explore the NABCEP Registered Course Catalog to find approved training providers that align with the certification you’re pursuing. Next, create a digital profile on the myNABCEP platform, where you can manage your registration and applications. If you want to test your readiness, consider purchasing and completing the ESIP Practice Exam.
Once you’ve achieved certification, use it to open doors to exciting and rewarding job opportunities in the energy storage sector.

Career Paths After Certification
Entry-Level Roles in Battery Energy Storage
Earning your certification opens the door to several practical and rewarding roles. Energy Storage Installers are responsible for setting up and maintaining battery systems for residential, commercial, and utility-scale projects. Their work includes system layout, permitting, structural assembly, and commissioning – essentially getting the systems up and running.
Battery Repairers focus on inspecting, testing, and repairing battery equipment. This includes handling electronics, fire suppression systems, and cooling mechanisms. This role often involves a two-year Registered Apprenticeship with the U.S. Department of Labor. Salaries for this position range from $50,500 to $90,500 annually.
Operations and Maintenance (O&M) Technicians ensure the long-term performance and safety of energized Battery Energy Storage Systems (BESS) by conducting safety inspections, electrical measurements, and equipment testing. The American Clean Power Association highlights the unique challenges of working with BESS:
"Battery Energy Storage Systems (BESS) are unique in that they cannot typically be fully de-energized and there are so many tasks to be performed by so few technicians, often without the specializations found in traditional generation facilities."
Construction Technicians handle the physical assembly and installation of battery systems before they become operational. Meanwhile, Energy Storage Service Specialists focus on maintaining and troubleshooting storage units. Many of these roles also require additional safety certifications, such as OSHA 10/30-hour training. These positions not only offer hands-on experience but also prepare individuals to work on broader renewable energy projects.
Opportunities in Renewable Energy Integration
Certification also opens up pathways in renewable energy projects that integrate battery storage with power generation systems. BESS systems are increasingly paired with solar and wind farms, often located in remote areas. These roles demand a combination of skills in both energy generation and storage. Certified technicians may work on microgrids, utility-scale projects, or solar-plus-storage installations that blend multiple technologies.
Starting as an entry-level installer can lead to advancement into specialized roles like Solar Project Manager, Utility Interconnection Engineer, or Residential PV System Designer with the right additional training. Organizations such as the American Clean Power Association are helping to standardize training, making it easier for certified professionals to pursue opportunities across different regions. Whether you’re working in a factory, a workshop, or out in the field, your certification serves as a strong foundation for growth in the ever-expanding renewable energy industry.
Conclusion
The field of battery energy storage is growing rapidly, and earning the right certifications can open doors to immediate career opportunities. Programs like NABCEP’s PV Associate, IREC’s Energy Storage Certification, and specialized BESS training equip professionals with the critical safety knowledge and technical skills that employers actively seek. As NABCEP states, their certifications aim "to advance industry standards, to provide a mechanism to document technician knowledge, skills and qualifications, and to promote a skilled energy workforce". These credentials not only validate your expertise but also demonstrate your ability to safely and efficiently handle complex, non-de-energizable systems.
