Switchgear, transformers and SCADA components for utility interconnection, sourced against real manufacturer lead times.

Source switchgear, transformers and SCADA components for utility-scale interconnection. HV substation equipment sourced with lead-time visibility on Sunhub.
Power transformer lead times have run six months or longer industry-wide, and sourcing here surfaces actual manufacturer lead time up front, since a late transformer order can single-handedly push back a project's interconnection date.
MV and HV switchgear specs get sourced against the specific requirements an interconnection study defines, not a generic substation package.
Supervisory control and data acquisition components get sourced to the protocol and reporting standard the interconnecting utility requires for handoff and ongoing monitoring.
Lead-time visibility means substation equipment gets ordered on a schedule that matches the project's interconnection date.
Specs get sourced against the actual study requirements instead of a generic substation configuration.
Main power transformers are long-lead, made-to-order items, and lead times have stretched considerably in recent years, often running well beyond a year. Because interconnection cannot happen without them, the transformer order frequently becomes the critical path for the whole project. Sunhub sources against real manufacturer lead times so the transformer is ordered before it turns into the bottleneck.
A utility interconnection typically requires a step-up power transformer, high-voltage switchgear and circuit breakers, protective relaying, disconnect switches, metering, and SCADA and monitoring for the utility handoff. The exact ratings and protection scheme come out of the interconnection study rather than a standard list. Sunhub matches switchgear and protection to that study so the equipment reflects what the utility actually approved.
It often does, because substation components have different suppliers, longer lead times, and tighter engineering requirements than trackers and modules. Treating them as one lumped order tends to hide the transformer's schedule risk. Sunhub sources the substation package against its own lead times while keeping it coordinated with module and tracker procurement so nothing falls out of sequence.
