Energy Storage System (ESS) Strategies


Peak Shaving – In a Time of Use (TOU) rate plan, an SCS ESS will discharge during peak hours when energy and demand rates are at their highest, and (re)charges during off peak times when rates are at their lowest. This is an effective savings technique when space is limited and solar is not feasible.

Arbitrage – In a Time of Use (TOU) rate plan were On-Peak and Off-Peak kWh rates are widely separated, an arbitrage model can be implemented to buy and sell power for profit. This usually takes at least a system size of 1MW.

Self-Consumption – When Solar is present, an ESS can charge from the surplus energy generated and be used to peak shave the “wing hours” of the profile, or the hours just before and after solar production begins and ends.
