An event’s power requirement is not just the audiovisual supplier’s equipment list. Producers must bring together the devices, locations, operating periods and service consequences across suppliers so the qualified electrical team can design and manage the actual installation.
What you will leave with: A consolidated equipment-and-use brief with unresolved requirements, change controls and continuity ownership.
Use this when
- Several suppliers bring powered equipment to an activation or temporary venue.
- A new appliance, display or operating schedule is added after the electrical plan was prepared.
This is producer information coordination, not electrical design or installation advice. HSE references concern Great Britain. Qualified personnel determine load calculations, protection, cable routes, testing and emergency arrangements under applicable requirements; do not attempt DIY fixes.
Collect equipment requirements from every operating team
List the equipment each supplier intends to use, its location, model and manufacturer-supplied electrical information. Include catering, registration, environmental control and operational support rather than only the stage. Request missing details from the supplying owner instead of estimating from the device’s appearance or its last use elsewhere.
HSE’s event electrical guidance identifies site layout, power requirements, environmental conditions and the timetable of demand among planning considerations. Translate those categories into a practical intake record for the qualified contractor. Keep original specifications attached and mark uncertainties. A spreadsheet that replaces unknown values with guesses may look complete while leaving the designer without reliable inputs.
Describe when and why each service is needed
Build a timeline showing setup, rehearsal, public operation, cleaning and breakdown requirements. Ask suppliers which devices operate together and which remain needed outside public hours. Do not assume a closed stage means refrigeration, registration reconciliation or another service can be turned off. The electrical owner determines the technical implications; the producer supplies the operational truth.
For each important service, record what happens if it is interrupted and who decides the response. Separate safety-critical functions identified by qualified owners from commercial preferences such as keeping a decorative screen running. Identify continuity requirements without prescribing a generator, battery or alternate circuit yourself. A list of priorities is useful only when the responsible technical and safety teams can connect it to an approved arrangement.
Reconcile the brief with site constraints and changes
Give the contractor the current site plan and relevant operating conditions through the venue process. Include planned equipment moves and areas affected by public access or weather, so the professionals can assess the installation. Keep the producer’s plan synchronized with the approved technical arrangement rather than drawing new cable routes on a creative layout without review.
When a supplier substitutes equipment or requests a new location, identify the changed requirement and return it to the electrical owner before connection. Do not treat an available socket as proof of spare approved capacity. Record the decision and update the operating brief so another team does not continue using the old location or schedule. Escalate unresolved dependencies while alternatives are still practical.
Confirm handover and the response to interruption
Before public operation, obtain the required qualified acceptance and operating handover through the event’s process. The producer checks that the agreed services and responsible contacts are represented, not whether the installation passes an improvised technical inspection. Make it clear who may operate, isolate or alter equipment and how other staff report a problem.
Rehearse a tabletop interruption with the relevant owners: which activities pause, how visitors receive accurate information and which services must remain under the established safety plan. Do not restart or reroute equipment independently to recover program time. After changes or an incident, record the approved operating state before resuming affected work. Preserve the final demand brief so future events can learn from actual needs without copying technical approvals into a different venue.
Make the reasoning concrete.
A fictional exhibition booth has an approved audiovisual setup. On opening morning, a supplier adds a heated demonstration appliance and asks a greeter to connect it to a nearby socket because the appliance is essential to the sales pitch.
Connect first and report later
Opening: Use the visible socket to avoid delaying the demonstration.
Hypothesis: The booth can open with the planned sales story.
Risk: The new demand and location are outside the reviewed arrangement.
Route the changed requirement before use
Opening: Give the appliance specification and operating need to the electrical owner and use an approved alternative while it is assessed.
Hypothesis: The operational change is incorporated into the actual plan.
Risk: The demonstration may need to wait or change format.
The producer keeps the appliance disconnected until the qualified process resolves the requirement. Staff receive an honest program update rather than being asked to improvise electrical work.
Take the questions into your next brief.
Use these prompts in your own notes. Nothing is submitted from this page.
Equipment
Which exact devices and supplier specifications are included?
Timeline
When must each service operate, including non-public periods?
Consequence
What happens if the service stops, and who decides the response?
Change control
Which substitutions or moves require renewed technical review?
Handover
Who may operate or change the installation, and how are problems reported?
Watch for the wrong conclusion.
- Collecting only the stage supplier’s power needs.
- Treating an empty socket as an approval for new equipment.
- Confusing a commercial priority with a safety-critical service.
Your next action
Ask every operating supplier for the exact equipment and use periods missing from the current event power brief.
