1. A method of operating a plurality of pump units associated with a high-pressure, high-power hydraulic fracturing assembly, the method comprising:
receiving a demand hydraulic horse power (HHP) signal for operation of the hydraulic fracturing assembly;
based at least in part on the demand HHP signal, operating all available pump units of the plurality of pump units at a first output power to achieve the demand HHP;
receiving a loss of power signal from one or more of the plurality of pump units,
designating one or more pump units of the plurality of pump units as a reduced power pump unit (RPPU) and the remaining pump units of the plurality of pump units as operating pump units (OPUs), wherein the OPUs include at least two pump units;
operating one or more of the OPUs at a second output power to meet the demand HHP signal for operation of the hydraulic fracturing assembly, the first output power being in a first range based on a maximum continuous power (MCP) level of the plurality of pump units, the second output power being greater than the first output power and being in a second range between the MCP level and a maximum intermittent power (MIP) level of the one or more OPUs; and
obtaining the second output power by operating a turbine engine associated with the one or more OPUs to above 100% of an MCP level of the turbine engine.
