Energy Storage functions and benefits – by Ignacio Salazar

The act of integrating an energy storage solution into a photovoltaic system, or acquiring a hybrid solution since day one, allows consumers to apply some of the following functions in their system:

  • Self-consumption maximization: allows the user to not only have an energy backup, but also use it when its more convenient to save money, for example during cloudy days.
  • Micro-network: in the event of a failure of quality or continuity of the electric service, a hybrid system allows to partially or totally supply the electric operation, avoiding operational costs from emergency plants, production stoppages, or maintain the quality of the energy while the fault is restored.
  • Displacement of charges: when operating under an hourly rate, an energy storage system allows to save money by using the rate in favor of the user, using the batteries capacity in “peak” hours and charging the batteries in “night” hours. This is known as Arbitration.
  • Consumption peak leveling: it is the most known function of the energy storage systems, in which the consumer takes advantage of the ability of the hybrid system to deliver firm power (kW) and thus do not buy the power from the public network, but only the difference.
