Disclosed is a system and method for integrating power distribution for subsea boosting and direct electrical heating (DEH) of at least one subsea flowline. A subsea power cable located in a subsea environment is electrically connected to at least one power generator at a topsides location and delivers power to a subsea switchgear module which connects to subsea adjustable speed drives (ASD). At least one pump motor is electrically connected to at least one of the ASD, and at least one capacitor bank is electrically connected to at least one of the subsea ASD. A subsea pressure boosting pump is driven by the pump motor. At least one capacitor bank is electrically connected to at least one of the subsea ASD. At least one DEH is electrically connected to at least one of the subsea ASD in series with the at least one capacitor bank and in contact with the at least one subsea flowline. Power is distributed to the boosting and DEH equipment more efficiently and cost effectively.
