A BESS controls the way a site uses power by integrating the battery with the existing energy system to flexibly store and discharge energy.
Connected Energy integrates with renewables like solar and wind to store excess energy at times of low demand so it can be used later. This optimises the energy used from renewables, reducing energy bills and a site’s carbon emissions from energy use. However, the BESS can go even further. By reacting to all the energy assets on site, the system can be programmed to react to the local situation – storing power when it’s available and discharging that power wherever on site it is needed. You can find out more about the benefits of this system by visiting our E-STOR page.
Furthermore, building owners can use BESS to reduce energy bills. Connected Energy’s smart systems can respond to changing electricity tariffs in real time, charging the batteries on low-cost, off-peak tariffs, then discharging that energy for use when tariffs are at their peak.
2. Solving a problem
Ultimately, battery energy storage systems are problem-solvers – essentially, they manage grid load demand by smoothing out energy use over the day and night.
Increasingly our battery energy storage systems are also used to support EV charging hubs. The battery can draw down power from the grid or from on-site renewables during periods of low demand, then provide that power to the charging points during peak periods. On sites with limited available power, this mitigates the need for an expensive grid infrastructure upgrade, while still providing the energy needed for effective EV charging during busy periods when lots of vehicles are plugged into the hub. Read more about how Connected Energy supports EV charging in our case studies.
Similarly, some buildings have spikes in load which require either a costly grid connection upgrade from your district network operator (DHO) or a BESS to provide that extra energy on demand. On a more micro level you can eliminate the use of diesel generators at peak periods, reducing carbon emissions.
