Less fossil fuel, more green energy. Generally speaking, that means a sharp increase in electricity consumption. And now the electricity grid is having trouble coping, you could be left with no power at all. So how can you still make sure your machines and building systems have enough power? Peak shaving is the solution for many. It uses an energy storage system, so you can spread out or ‘shave off’ the peaks in your energy consumption.

As a construction company, you need much less power during the night than during the day. That’s because early in the morning, when all machines start working and the heating or cooling in the site cabin or office is turned up a notch, power consumption shoots up. Then you might experience that the 3 x 250 ampere connection you want power from can’t give enough power to keep everything running during peak times. That’s when you get the message that due to grid congestion, it will be weeks or months before a heavier connection may be available.

This is where peak shaving comes into action. It literally help you to shave off the sharp peaks in power demand. The method most commonly used is a battery system with sufficient storage. You let the battery steadily recharge at night – in the (cheap) off-peak hours – because then the electricity grid can supply enough and only the camera security and emergency lighting are on at the building site. If you run into a power shortage at some point during the next working day, the battery system automatically kicks in and you won’t notice any grid congestion.
