The project at NYPA is using the energy storage system to demonstrate a peak shaving function that reduces the peak load typical of a commercial building.
Motivated by a tariff system consisting of an energy demand charge and a peak power tariff, the aim of state-of-the-art peak shaving is to minimize the maximum power peak value at one specific …
The benefit in Scenario 2 mainly comes from the reduction of energy cost (689 $) and peak capacity cost (236 $) due to peak-shaving energy storage. The peak capacity is reduced by 0.70 MW from 7.66 MW to 6.96 MW.
Recent data highlights that during peak demand periods, electricity prices can spike to alarming levels, with costs soaring up to three times the average rate.
Time-of-use (ToU) pricing is widely used by the electricity utility to shave peak load. Such a pricing scheme provides users with incentives to invest in behind-the-meter energy storage and to shift peak load towards low-price intervals. However, without considering the implication on energy storage investment, an improperly …
