Demand Charge Reduction
Similar to other cases, electricity storage can be used by the end-user who must pay an incremental amount (typically each month) for the peak power delivered for any 15-minute period during that month. This is a negotiated cost and is based on the amount above some base value. It is a single value, say 5 $/kW/month and changes from month to month as the demand changes. The user typically controls certain parts of the load, such as air conditioning, large pumps, etc to keep the demand charge under control. Onsite electricity storage provides the user with additional control of process costs and allows control of the demand charge so it is less of a factor in determining facility operation.
