What Are The Benefits?

Good for Your Wallet, Better for the Earth: The Benefits of HESS

Energy Independence

A battery storage system allows you to store electricity on cheaper tariffs during the night. This stored energy can then be used during peak demand times, reducing your reliance on the grid and potentially lowering your electricity bills.

Time-of-Use Savings

Many utility companies have time-of-use (TOU) pricing, where electricity costs more during peak demand hours and less during off-peak hours. A battery system can allow you to store electricity when rates are low and use it when rates are high, helping you save on your energy bills.
