The Course in BESS Sizing and Load Management at ICTESS trains specialists to design, calculate and manage battery energy storage systems. The program runs from electrochemical fundamentals to advanced energy management strategies, and it covers the Battery Energy Storage System (BESS) technologies most widely used in renewable projects and behind-the-meter installations.
You will learn the sizing calculations used on real projects: usable capacity based on depth of discharge (DoD), charge and discharge rates (C-rate), energy management system (EMS) configuration, hybrid inverter compatibility and battery-specific electrical protection designed to NEC Article 706 and UL 9540. The course ends with a Capstone Project where you apply everything you have learned to a complete BESS sizing project.
The Course in BESS Sizing and Load Management responds to the growing need for technical professionals who can design energy storage and integrate it into renewable and behind-the-meter installations. The industry needs specialists who understand battery chemistry, load management algorithms and the sizing criteria that protect system performance and service life.
The course prepares you to size complete storage systems around critical parameters such as cycle life, charge and discharge rates, depth of discharge and round-trip efficiency. You will learn to select the right battery technology for each application, configure EMS strategies for peak shaving and time-of-use arbitrage, and integrate BESS with hybrid inverters so that the equipment is fully compatible and performs at its best.
The program includes professional calculation tools for battery sizing and charge cycle simulation. It closes with a Capstone Project where you develop a full BESS sizing project using every technical skill you gained during the course.
The Course in BESS Sizing and Load Management prepares you for specialized technical roles at solar and storage installers, PV engineering firms, energy storage integrators and the technical departments of equipment distributors.

Battery energy storage is growing quickly as renewables and behind-the-meter generation expand. Utilities, developers and commercial customers across the United States are adding storage to manage peak demand, firm up solar output and improve grid reliability, which creates strong demand for technicians who specialize in battery system sizing and management.
Shortage of storage specialists: Few professionals have mastered BESS-specific sizing calculations. Many solar technicians lack dedicated training in battery chemistry, cycle life analysis and EMS configuration, and quality projects that deliver performance and durability depend on all three.
Storage is becoming standard in new renewable projects: Market conditions and utility programs are pushing solar and wind toward hybrid designs with storage. More and more projects include BESS to reduce curtailment, participate in ISO/RTO ancillary services markets and use more of the energy they generate on site. All of this requires professionals who can size these systems correctly.
Competitive edge in a changing market: A BESS specialization sets you apart from generalist technicians. Knowing battery chemistry, capacity calculations, EMS strategies and NEC 706, UL 9540 and NFPA 855 makes you a top candidate at companies leading storage integration on the U.S. grid.
Completing the Course in BESS Sizing and Load Management positions you in one of the fastest-growing segments of the renewable energy industry. Energy storage is key to integrating large amounts of solar and wind, which creates steady demand for technicians who can size and manage BESS in behind-the-meter, commercial and industrial, and utility-scale projects.
Specialization in a technology critical to the energy transition: BESS is essential for managing the variability of renewables. Mastering BESS sizing makes you a sought-after professional for installers, engineering firms and developers that need to add storage to their solar and wind projects.
Distinct technical skills: You will learn BESS-specific sizing calculations that general programs rarely cover: C-rate analysis, optimal DoD, cycle life estimates based on use, and EMS strategy setup. These skills set you apart in hiring processes across the industry.
Ability to optimize existing systems: Beyond sizing new systems, you will be able to assess and improve existing BESS installations. That includes analyzing degradation, proposing augmentation and fine-tuning charge and discharge strategies to maximize return and service life.
ICTESS professional certificate: The ICTESS professional certificate documents your technical specialization in BESS sizing and load management.

Program details
The Capstone Project is the final stage of the program and brings together all the technical skills you develop during the course. You will complete a real-world BESS sizing project from energy demand analysis to protection specifications, using the same professional methods and calculation criteria applied across the industry.
The project must include a load profile analysis of the target facility, a justified choice of battery technology for the application, a usable capacity calculation based on DoD, C-rate and estimated cycle life, and battery bank sizing with its series-parallel configuration. You will also specify a compatible hybrid inverter, configure EMS strategies (peak shaving, behind-the-meter optimization, backup power) and design the electrical protection scheme, including BMS, fuses and disconnects, in line with NEC Article 706.
The project also includes a simplified economic analysis of the BESS that estimates payback from utility rates, demand charges and the usage profile, along with equipment specifications and justified selection criteria. The final documentation must meet the professional standard of an AHJ permit submittal package. It should show that you can deliver rigorous, complete BESS sizing work that you could present to clients or include in the construction documents for a hybrid system.
The Course in BESS Sizing and Load Management at ICTESS teaches the professional calculation methods technicians use to size storage systems. You will calculate the usable capacity of battery banks based on depth of discharge (DoD), round-trip efficiency and charge/discharge rates (C-rate). You will analyze cycle life by usage pattern, estimate annual degradation and configure EMS strategies for peak shaving, time-of-use arbitrage and demand charge management. You will also work with technical spreadsheets for sizing and equipment selection, using the same criteria that specialized engineering firms apply on their storage projects.
You do not need to be an engineer, but a technical background in electrical work, electronics, renewable energy or building systems is recommended. The course is designed for experienced solar installers, electricians, graduates of electrical or renewable energy associate degree programs and engineers who want to specialize in storage. You should know basic electrical concepts (voltage, current, power), be able to read one-line diagrams and be familiar with behind-the-meter solar systems. If you work regularly with inverters, solar panels or electrical installations, you already have the foundation to get the most out of the course.
The ICTESS professional certificate documents your technical specialization in BESS sizing and load management as professional development. It is not an accredited academic degree or a state license, but it shows specific, in-demand skills: battery capacity calculations, cycle life and degradation analysis, EMS configuration and protection design for storage systems. Installers, renewable engineering firms and equipment distributors value hands-on technical training like this because it shows up-to-date knowledge in a field where qualified professionals are hard to find.
The Course in BESS Sizing and Load Management stands out for its engineering-focused approach to sizing real storage systems. Many programs offer a general overview of batteries or cover only physical installation. This course goes deep into the parameters that determine system performance and service life: battery chemistry and degradation, usable capacity with DoD and C-rate criteria, advanced EMS strategies and technical compatibility with hybrid inverters. It also covers complete BESS protection design under NEC Article 706, UL 9540 and NFPA 855, a skill that general storage training rarely addresses.
