Many control strategies of peak shaving by thermal energy storage were developed to achieve daily or monthly electricity cost savings [21, 22]. Due to the small discharging power capacity of the battery storage, its peak shaving potential (ΔPeak = 16, 16, 10 kVA) is smaller compared with the TES tank (ΔPeak = 32, 38, 62 kVA).
The impact of solar on peak demand. Peak demand typically occurs during the heat of the day in summer, which are the exact same times when solar panels produce the most electricity. As a result, solar can help offset your pull from the grid during those peak hours, lowering the overall need for power and reducing your individual peak
