What does "Behind the Meter" mean?

Every electricity consumer has meters in their premises that calculate how much energy in kWh was taken from the grid. 

In simple terms, everything that happens on site, on the energy consumer's side, is "behind the meter" and, in turn, everything that happens on the grid side is then considered to be in front of the meter.

Until recently, there wasn't much you could do behind the counter to save money, except turn off the lights and machines when they weren't needed.

There has been a recent shift in the world's awareness of renewable energy. There are now a number of ways for companies to minimise electricity costs and optimise their energy balance.
