Why do we reduce only current to prevent power loss? Why not voltage?

$begingroup$ One may actually benefit from lower voltage if a parasitic parallel resistance is also a concern (this answer deals only with parasitic series resistance). E.g. if the isolation between the wires cannot be considered ideal and allows for some current. In this case, one may want to lower the voltage in order not to dump too much power into the insulation.

What voltage does a low voltage grid supply operate at?

The low voltage grid supply in the UK operates at voltages and frequencies harmonized by BS EN 50160, i.e. at 230/400 V 50 Hz a.c. (or 230 V 50 Hz a.c. for three-wire three phase systems earthed at one of the phases).

What are electrical energy storage systems (EESS)?

Electrical energy storage systems (EESS) for electrical installations are becoming more prevalent. EESS provide storage of electrical energy so that it can be used later. The approach is not new: EESS in the form of battery-backed uninterruptible power supplies (UPS) have been used for many years. EESS are starting to be used for other purposes.

Are energy storage devices dangerous?

energy storage devices can often supply significant short-circuit currents. Even at extra-low-voltage (ELV) this can present a serious risk of overheating and could lead to burns and/or fire. means of protection against electric shock may be exacerbated when the installation is operating off grid.
