Power without
the noise.
Diesel generators shout at 85–100dB. JAM Power BESS systems are inaudible. That’s not just more pleasant — it changes what’s legally possible on your site.
Hear the difference
Toggle between a diesel-powered site and a JAM Power site — the sound rings show what’s radiating from your power source.
What silence unlocks
Noise isn’t just a nuisance. It determines what you can legally do, when, and where. 0dB operation changes the rules of the game.
Noise-restricted hours on construction sites typically ban generator use after 18:00. JAM Power lets you work through the night legally — extending productive hours without a planning variation.
Unlocked with BESSPlanning conditions near homes, hospitals, and schools often set 55dB daytime limits — below what a diesel generator can achieve even with attenuation. BESS is the only solution that reliably meets these conditions.
Diesel cannot complyA single diesel generator within earshot destroys location audio. JAM Power is invisible to microphones — no sound recordist has ever asked us to turn off a BESS unit between takes.
Used on 40+ productionsProlonged exposure above 80dB requires mandatory hearing protection under UK law. A silent site removes that obligation entirely — and makes the working environment measurably better for everyone on it.
HSE compliant by defaultHistoric England, the National Trust, and local planning authorities regularly prohibit combustion engines near listed buildings and conservation areas. BESS is approved where generators are not.
Diesel often refusedFestival and outdoor event noise licences set strict dB limits at the boundary. Diesel-powered infrastructure adds to your noise budget before a single speaker fires. BESS uses none of it.
