The MPU is configured to generate voltage that matches the requirements of an electrical bus from the at least one switch gear such that a combined electrical current generated as a result of the generated voltage is provided to the electrical bus to the components of the hydraulic fracturing system. Further, the hydraulic fracturing system may include electrical fracturing equipment with at least one second switch gear to support the at least one first switch gear in handling electric power from the MPU. A datavan may be included in the system to control load shedding, load sharing, and power distribution for the electrical fracturing equipment comprising the at least one second switch gear. ## Claims ### Claim 1 A hydraulic fracturing fleet, comprising: a datavan for engaging an interchangeable combination of diesel-powered components and electric-powered components, the diesel-powered components and the electric-powered components comprising at least one back-up component that is either or both of diesel-powered and electric-powered;
