Shared depot charging needs an operating agreement

Two fleets can share an address while operating to very different timetables. A charging installation that appears ample in aggregate may become contested when vehicles return together or depart early. A practical operating agreement is needed to translate shared infrastructure into dependable preparation for each user's work.

Map the competing schedules

Document arrivals, departures and charging needs for each vehicle group. Include changes between weekdays, shifts or service types. The aim is to understand when users need the same resource, not simply to total their vehicle numbers. Review the site's other activities so charging access is considered within the complete depot operation.

Agree what information each group will provide and how often it will be updated. A charging priority based on yesterday's schedule can be inappropriate after an urgent reassignment. Define how dispatch changes enter the process and who resolves a conflict. Shared use requires an accountable decision point rather than several informal instructions to drivers.

Clarify access and occupation

Decide which bays are allocated, which are shared and what happens after charging completes. Vehicle movements needed to free a connection create work and may introduce conflicts with loading or pedestrian routes. Include these movements in the site review and agree which authorised staff perform them.

Set understandable instructions for drivers from every participating group. Identification, authentication and fault reporting should be consistent enough to use without local knowledge. A visitor or relief driver should not need to discover a different unwritten practice at each bay. The operating agreement should support a clear routine at the point of use.

Separate allocation from billing

Agree how charging sessions are attributed and how shared costs will be handled. Identify the data source and the process for resolving incomplete records. The fleet should understand the distinction between energy delivered to vehicles and other infrastructure or service costs that may be part of the commercial arrangement.

Do not let the cost allocation mechanism silently determine operational priority. The departure that matters most to the service may belong to the group using less energy. Define charging priorities explicitly and evaluate the control system against them. Energy Saving Trust's load management guidance offers context for assessing how available power can be distributed.

Govern faults and future change

Nominate the party responsible for support requests, supplier coordination and communication to users. Shared equipment can remain faulty longer when every participant assumes another has reported it. Make escalation and updates visible, including how an unavailable bay changes the allocation of remaining capacity.

Review the agreement when vehicle numbers, users or operating hours change. A sharing arrangement should be flexible enough to evolve while preserving clear responsibilities. Its value comes from combining infrastructure with a workable service: users understand access, dispatchers understand priorities and management can see whether the shared arrangement continues to support the work expected of it.
