This customer had a very specific brief that outlined a desire for cost savings by arbitrage. Energy arbitrage is the practice of profiting from the price difference of energy at different times. A battery storage system can exploit a Time-of-Use (TOU) tariff, which charges varying electricity rates depending on the time of day. The battery system charges itself during off-peak hours when electricity is cheaper and then discharges stored energy to power a load during peak hours when electricity prices are significantly higher, effectively "buying low and selling high" the energy to itself and reducing overall energy costs. With such a system we managed a stellar pay-back period of 4 years and 7 months, and an IRR (Internal Rate of Return) of 18,7% on the investment.
We deployed a BESS system with a 10-year warranty, that boasts it's own built-in fire-suppression system, and is liquid-cooled which optimises battery performance and longevity. The system does not need to be containerised and is rated IP67.
