Components of Commercial Energy Storage Systems

Lithium Ion Batteries

The high efficiency of the energy storage system is guaranteed by the advanced battery technology and the integrated BMS. The lithium battery has a reduced environmental impact combined with excellent performance and safety. The ideal battery bank for the project is defined according to the type of application, storage capacity, charging/discharging capacity, service life, etc. Lithium batteries are used because they provide several advantages in relation to the other topologies used worldwide – among them, high energy density, extended useful life, high charging and discharging capacity, modularity and low maintenance.

The figure below shows the modularity of these batteries; the cells are enclosed in modules and mounted on racks. Each rack has its energy measurement, control and management unit (BMS).

Designing a Commercial Energy Storage System According to Application Demands

Designing a commercial energy storage system requires a tailored approach based on specific application demands. Here are the key steps to consider:

Calculating the Cost and Benefit of a Commercial Energy Storage System

Determining the cost and utility of commercial energy storage systems involves considering numerous factors and variables. Here’s a systematic approach to assessing the economics:

Identify Key Cost Components

Identify the Applications

Determine the primary services or functions the energy storage system will provide, such as frequency control, renewable energy integration, backup power, or peak shaving. Some applications may require multiple or hybrid energy storage solutions to meet various objectives.

Define the Performance Metrics

Establish critical factors that will determine the system’s success. These may include:

These metrics will depend on the specific applications and grid conditions.

Calculate Lifetime Costs

Total Lifetime Cost : Sum of all the costs over the system’s lifespan, including capital, operation, maintenance, degradation, and additional costs.

Estimate Lifetime Energy Production

Determine the total energy the system will produce over its lifespan, considering its performance, efficiency, usage patterns, and application (e.g., peak shaving, frequency control).

Levelized Cost of Storage (LCOS)

Technology Selection

Choose the most suitable energy storage technologies to meet the performance metrics. Options include:

Each technology has advantages and disadvantages regarding cost, performance, lifespan, safety, and environmental impact.

Design the System

Configure and integrate the energy storage system with other components:

Evaluate the System

Test and validate the energy storage system:

By following these steps, you can design a commercial energy storage system that meets specific application demands and performs efficiently and reliably.

Evaluate Revenue Streams and Avoided Costs

Identify potential sources of revenue and cost savings:

Compare LCOS with Revenue and Savings

Assess the profitability of the storage system by comparing the LCOS with the combined revenue and avoided costs:

Account for Uncertainty and Sensitivity

By following this approach, you can systematically evaluate the cost and benefit of a commercial energy storage system, ensuring a transparent and comprehensive economic assessment.

Connecting Commercial Battery Storage Systems with Photovoltaics

Yes, commercial battery storage systems can be connected with photovoltaics (PV) to create a solar-plus-storage system. This configuration allows you to store excess solar energy generated during the day and use it at night or during grid outages. It enhances solar power self-consumption and reliability while reducing demand costs and grid fees.

A solar-plus-storage system can also participate in energy markets, offering grid services like frequency management, voltage support, demand response, and energy arbitrage. This makes it a financially viable and environmentally responsible option for businesses.

Where to Buy Commercial Energy Storage Systems

You can purchase commercial energy storage systems from manufacturers, integrators, or distributors. Another option is to work with an energy-service company that can design and install a customized system tailored to your needs.
