Energy Management System (EMS): A Guide To Optimising Battery Storage
What is an Energy Management System (EMS)?
By definition, an Energy Management System (EMS) is a technology platform that optimises the use and operation of energy-related assets and processes. In the context of Battery Energy Storage Systems (BESS) an EMS plays a pivotal role; It manages the charging and discharging of the battery storage units, ensuring optimal performance and longevity of the batteries which ultimately determines the commercial return on investment.
According to a recent World Bank report on Economic Analysis of Battery Energy Storage Systems May 2020 achieving efficiency is one of the key capabilities of EMS, as it is responsible for optimal and safe operation of the energy storage systems. The EMS system dispatches each of the storage systems. Depending on the application, the EMS may have a component co-located with the energy storage system (Byrne 2017).
Key components of an EMS (Podium example)
Cloud-based optimization engine
This core of the Podium platform is where the magic happens. Utilising cloud computing in solar battery storage, the optimization engine processes vast amounts of data to make intelligent decisions about energy usage. It analyses patterns in energy consumption, predicts future needs, and optimises the flow of energy accordingly.
Portal Interface
Accessibility and user-friendliness are key, and the portal interface of Podium delivers on both fronts. This intuitive interface allows users to interact with the system, providing real-time insights and analytics. Users can monitor their energy consumption, view performance reports, and even control various aspects of their energy system.
Edge controller device
Acting as the physical connection between the digital and real world, the edge controller device is a critical component. It’s responsible for implementing the decisions made by the optimization engine. Whether it’s managing the flow of energy from renewable sources, controlling battery storage systems, or integrating with the grid,

How an EMS reduces site operating costs
Real-time monitoring
EMS provides constant monitoring of all energy-related systems and processes. This continuous oversight generates a wealth of data, offering deep insights into energy usage patterns and inefficiencies. By identifying areas where energy is wasted businesses can take immediate corrective actions.
Predictive maintenance
EMS leverages data analytics to predict when equipment requires servicing, shifting the maintenance approach from reactive to proactive. By anticipating and addressing system inefficiencies before they escalate into costly repairs or downtimes, businesses can avoid significant expenses.
Optimised energy consumption
Sites can automate and optimise their energy consumption based on real-time demand. This involves scheduling high-energy-consuming activities during off-peak hours to benefit from lower energy rates and reducing usage during peak periods to avoid high demand charges.
Considerations for EMS installation for your site
Choose the best-aligned partner
Begin by identifying potential EMS providers like Wattstor who have experience in your industry and with renewable energy storage. Look for partners with a proven track record of successful implementations and a strong support structure. It’s crucial to choose a partner who understands your specific needs and can offer a tailored solution rather than a one-size-fits-all approach.
Evaluate existing energy consumption
A comprehensive energy audit is the foundation of any effective EMS implementation. This audit should assess not just overall energy consumption but also peak demand times, inefficiencies, and potential areas for integration of battery storage solutions. Understanding your current energy profile helps to determine the scope and scale of the EMS required.
Configure an optimal EMS platform for your site
When selecting an EMS, consider the size of your business, the complexity of your energy needs, and the specific benefits you seek from incorporating battery storage. For businesses with fluctuating energy demands or those looking to capitalise on renewable energy, an EMS that efficiently manages battery storage can be invaluable.
