In the US, it is mainly 120-240 volts. Most appliances run on 120, with 240 being used for ranges, water heaters, clothes dryers, and large air conditioners. In Europe, much of the power is 240 volts.
Your home is supplied at a fixed voltage that depends on which country you are resident in. Home supplies are provided at voltages between 100 v and 240 v in the majority of countries.
It depends where you live. In North America, the nominal voltage is 240/120 V, whereas in Europe it's 230 V.

A transformer changes the electricity from one voltage to another, which allows a high voltage power line to be converted down to a voltage suitable for home usage.
We deliver power on the power grid as an AC voltage. That's alternating current, and that's what is available in your home.
Power = (current) times (voltage)Current = (Power) divided by (voltage)Voltage = (Power) divided by (current)
The unit of power is watts, the unit of current is amps, and the unit of voltage it volts. Power = Voltage X Current Voltage = Power / Current Current = Power / Voltage In electricity, power is symbolized with a P, current with an I, and voltage with a V. The real formula looks like: P = V x I V = P / I I = P / V
KVA is a measurement of power; kV is a measurement of voltage. You're asking "What is the power for voltage?", which makes no sense. Power = Voltage times current.

Power is contituted by both current and voltage So we consume both current and voltage
The capacity of the regulator is measured in Watts (Power) and that is the voltage multiplied by the current.

Voltage isn't "shipped", really. Generator terminal voltage is typically in the range of 10-30kV; they are connected to the bulk electric system by step up transformers that convert this 10-30kV into voltage in excess of 100kV for power transmission. Near your home, this voltage is again stepped down to sub transmission voltage levels, then distribution voltage levels. The small power lines near your home are probably distribution level power lines (often 2 - 20kV); these will have a center tapped step down transformer to connect your home, at 120volts, to the grid.
Transformers transform low vvoltages to hivh and vice versa. This is important in transmitting electrical power form the high voltage power plant to the low voltage home voltage. Using high voltage transmission reduces transmission power losses, I2R.
You cannot power a home with car batteries. Batteries are DC voltage. Your home operates on AC voltage. You could use a converter but the number of batteries required to operate an average home would be enormous.

Power = voltage * current. Without current, relating voltage to power is meaningless. One thing I can say is the voltage should be dictated by the amount of losses that is acceptable - the cabling you use to transfer the power to your home will have a specific resistance per unit length, which is unchanging. If you choose to use a low voltage, you will in turn use a fairly high current to transfer the energy you want. The power lost in the cable will be P = R * I^2. This loss can become significant, dictating a higher voltage.

There is no choice of what voltage that you are supplied for your home. You are governed by what the utility company in your area supplies.
