battery energy storage systems (BESS)

Battery Energy Storage Systems (BESS) are known by a number of different names including utility battery storage, solar battery or electricity storage. BESS are now an accepted part of the options available to commercial consumers and utility electricity suppliers. They offer significant benefits by providing greater control of energy assets, increased efficiency, and improved reliability. Energy Storage Solutions are perfect for New Zealand and the Pacific Islands (Fiji, Samoa, Cook Islands, Niue, Tuvalu, Tokelau, Tonga) where aging utility infrastructure is in need of significant investment. 

Utility-scale batteries offer some significant advantages over other solutions as they can often be installed within existing infrastructure to provide better energy security at a fraction of the costs of a complete utility infrastructure upgrade. Common problems PowerSmart has solved using utility-scale batteries include:

  • Renewable microgrids or mini-grids - a great alternative to diesel generators. 
  • Energy security - instant and seamless energy security for manufacturers and food storage
  • Peak shifting - reducing demands on energy infrastructure by moving energy loads.
  • BESS offer a number of advantages over other solutions:
  • Scalable - increase the number of batteries to cope with growing demand in the future
  • Instantaneous - can meet fluctuating demand effortlessly
  • Long-term warranty
