Pulse loads are the part of an industrial load profile that the headline kW figure usually hides. A spot-welding line, an induction furnace charge, or a hydraulic press cycle delivers energy in joules over a fraction of a second, and the peak watts during that window can be ten times the average draw the meter records over a half-hour. That matters for cable sizing, for breaker selection, and for whether the site is paying capacity charges sized for the peak it occasionally hits rather than the load it usually runs.
Demand profiling on this kind of plant is where the engineering and the commercial work meet. A facility that smooths pulse loads with a flywheel UPS or a small behind-the-meter battery can shave the peak the network sees, drop a band on its MIC, and avoid the capacity uplift the DNO would otherwise quote at six-figure connection-charge level. The maths starts with knowing the joules per pulse, the cycle rate, and the watts that the network and the LV switchgear actually have to deliver.
Purely Energy has worked through these conversations on sites where the peak demand profile drives the procurement choice as much as the annual kWh does. Time-of-use tariff selection, capacity charge optimisation, and DSR participation all hang off an accurate load profile, and that profile only holds up if the underlying energy and power numbers are honest. The free tools here are step one of that audit, and the half-hourly data review is step two. By the time the procurement strategy is signed off, the joules-per-pulse number sits in a spreadsheet alongside the capacity charge model and the contract recommendation.
