Behind the meter BESS
Behind the meter C&I BESS (commercial and industrial battery energy storage systems) have become vital for businesses aiming to enhance their energy efficiency and reliability. Whether you are running a mining, metals, data centre, hospital, airport, cold storage facility, EV charging hub, manufacturing plant or some other kind of energy-heavy enterprise, here’s why C&I BESS is important:
Cost savings
By storing energy during off-peak hours when electricity prices are lower, businesses can use this stored energy during peak times, significantly cutting energy costs depending on your tariff structure. With intelligent scheduling tailored to your consumption patterns, a Brunstock BESS automates this process, charging during solar or wind excess, discharging overnight or when electricity rates spike.
Reducing demand charges
Demand charges can account for 30–50% of commercial electricity bills, calculated on your highest 15- or 30-minute usage in a billing period. A single spike, starting a motor, running a chiller (air conditioner) or charging an EV
fleet, sets your demand charge for the entire month. C&I BESS smooths these peaks by discharging stored energy the moment demand rises, keeping your peak below threshold and your bills under control. Operational efficiency is improved at your sites by storing excess energy during low-demand periods. C&I BESS systems can supply this stored energy during peak usage times.
This helps industrial enterprises manage their energy more efficiently and avoid the high costs associated with peak energy rates.
Enhanced resilience
Power outages can be catastrophic for medium to large businesses, causing operational disruptions and financial losses. Brunstock BESS provides seamless backup power with less than 20 milliseconds transfer time, fast enough that servers stay online, refrigeration continues and production lines keep running. With black start capability, your site can restart from a dead grid without waiting for utility restoration.
Together, these benefits make Brunstock C&I BESS a smart investment for businesses looking to optimise their energy management and ensure operational continuity. Whether it’s about financial prudence or operational resilience, these systems deliver on multiple fronts.
What does peak shaving mean in BESS?
Peak shaving means capping how much power you draw from the grid at any moment. When your site demand approaches a set threshold, the BESS automatically discharges to cover the difference, ‘shaving’ the peak off your load profile.
The result: lower demand charges, reduced network tariffs and potentially a smaller connection agreement. For facilities with variable loads—motors, compressors, air conditioners, EV chargers etc.—this can deliver payback within a short period.
Brunstock’s C&I BESS systems offer a reliable backup power source, enhance energy management and provide substantial cost savings through peak shaving. They’re an invaluable asset for any industrial facility aiming for both financial and operational efficiency.
