What an EV Depot Actually Needs

What an EV Depot Actually Needs

“The same deployment model that proved the platform at First Bus and Warrington, rescued Lothian’s operations when EO Charging failed.”

The Crisis

The Crisis

When a critical operator’s charging platform collapsed overnight, Edinburgh’s buses couldn’t wait.

Optimo replaced the entire system in 48 hours. Every bus pulled out on time.

Lothian Buses operates one of the UK’s most demanding urban bus networks. When the platform failed, the operational consequences were immediate and public.

The rollout

The rollout

Live system in days. Value in weeks. Revenue in months.

Optimo deployed on-site with one objective: full operational control within 48 hours, with no loss of charging capacity and no disruption to overnight operations. The transition was sequenced transformer by transformer, with every charger live on Optimo as it was reconfigured.

The Revenue Opportunity

The Revenue Opportunity

Operational stability was the immediate objective — but Optimo is an energy operating system, not a rescue platform. With the depot stable, Lothian can unlock the next layer of value from infrastructure they already own.

What This Means

What This Means

Most platforms take weeks to deploy. Optimo was live across a 109-connector depot in 48 hours — under emergency conditions, with the entire morning pull-out depending on the outcome.

What Changed

What Changed

Optimo mapped the full depot layout in hours. Every charging row was configured with its own scheduling logic and departure-order priority structure. Power is now distributed dynamically across the site with no manual overnight intervention.
