Quintana Infrastructure & Development LLC (QID) is an investment holding and operating company owned by William K. Robertson and organized in 2011.

QID is a holding company making investments and managing the operations of assets for itself or on behalf of like-minded partners. QID seeks to make adaptive infrastructure investments across energy and power; data and technology infrastructure; industrial end markets; and resource management.


QID’s purpose is to safely, responsibly and creatively invest capital and manage assets that deliver superior returns for their stakeholders. We focus on management and field-level personnel who make honest, deliberate, nimble and value-guided decisions. Capital, assets and/or equipment are instruments through which our people serve our customers.

QID aims to steward assets for the long-term so that customers will be happy today and comfortable in sustaining their commitments tomorrow. QID remains opportunistic in its investment selection, and importantly in its timing. QID has no forcing function with respect to investment hold periods, preferring to prepare for a long-term hold, but ready and willing to monetize as market conditions precipitate favorable opportunities. QID maintains an eye for generational assets, or those that offer long-term, stable and inflation-protected returns.
