Shore Hotel in Santa Monica, California, is a luxury establishment with an energy storage system and fast DC electric vehicle (EV) charging — reportedly, the first one in the US to have this setup. It is expected that the lithium-ion energy storage system will help it reduce electricity demand charges by 50%. Over time, that savings

When an EV is plugged into a charger, electricity demand increases, so the hotel could be on the hook for a high rate for the electricity, depending on the time of day. Demand charges are based on the highest rate for 15 minutes in a billing cycle. So, obviously, a business would want to avoid spikes in electricity usage so it would not have to pay that rate.

That’s where the energy storage comes in. When there is a spike, electricity can be used from the energy storage system, instead of from a utility’s electricity. Avoiding demand charges in this way, as noted above, can thus help businesses save money. […]”<
