Applications and advantages

Understanding C&I client needs

C&I clients typically have more complex energy requirements than residential clients. These often include the need for effective demand charge management and time-of-use cost-shifting. Demand charge management involves using energy storage to reduce peak demand and, consequently, the associated demand charges. On the other hand, time-of-use cost-shifting leverages the storage system to capitalize on differences in energy prices throughout the day. Installers venturing into the C&I sector need to be well-acquainted with these concepts. Familiarity with how battery storage can be tailored to address these specific needs is crucial for delivering value-added solutions to C&I clients.

Energy cost management

One of the primary advantages of C&I battery storage systems is their ability to manage energy costs effectively. These systems enable businesses to store energy when prices are low (usually during off-peak hours) and release it when prices are high (peak hours). This strategic shifting helps reduce energy expenses and plays a significant role in load balancing. By aligning energy usage with periods of lower costs, businesses can potentially reduce their overall energy bills.

Enhancing solar use

Battery storage systems also significantly enhance the use of solar installations in the C&I sector. They allow sites to store solar energy generated during peak sun hours, which can then be used during the evening or on cloudy days. This capability is particularly beneficial as it maximizes the use of generated solar energy, ensuring that the excess energy produced is not wasted but rather utilized effectively. It also contributes to a more consistent energy supply, mitigating the intermittency typically associated with solar power. Financial studies have shown that the addition of solar to battery storage in the C&I space can improve ROI, reducing the payback time of these investments.

Backup and resilience 

On-site battery storage is critical in providing backup power and resilience, particularly for facilities that require an uninterrupted power supply, such as data centers, hospitals, and universities. Consistent power is vital for data centers to maintain data integrity and operational continuity. In hospitals, battery storage systems can be lifesaving, powering essential medical equipment during emergencies. Universities also benefit, as these systems can maintain research integrity and provide a stable learning environment. This aspect of battery storage enhances operational reliability and significantly contributes to organizational resilience against power instability.

Transitioning from residential to commercial installations

Technological integration

The transition from residential to commercial battery storage installations is marked by the need for greater technological integration and settings tailored to business operations. This integration is crucial to maximizing potential and scalability for businesses. Developers are exploring new states with lower development costs and rising electricity rates, meaning that there is a need to support this growth in areas with growing energy storage demands. 

Addressing common installer challenges 

While a promising venture, installers transitioning to commercial installations may need to get creative in the face of some challenges. One of those challenges is the availability of rebates and incentives that increase the ROI for C&I investment in energy storage. Because rebates and incentives are geographically dependent, ROI will vary from place to place, making the sales pitch different depending on the location.

Training and expertise

Leveraging NABCEP, HeatSpring, and Briggs & Stratton training for continuous learning can help support the additional knowledge needed to break into the C&I market for battery storage installations.

Setting customer expectations

Proper communication with clients about what to expect from their battery storage system is crucial. This includes being transparent about the systems’ power output and backup duration.
