Energy storage can facilitate both peak shaving and load shifting. For example, a battery energy storage system (BESS) can store energy generated throughout off-peak times and then discharge it during peak times, aiding in both peak shaving (by supplying stored energy at peak periods) and load shifting (by charging at off-peak
