1. A non-transitory, computer-readable medium comprising instructions that, when executed by processing circuitry, are configured to cause the processing circuitry to:
receive input data;
determine available power from an intermittent power source based on the input data, wherein the intermittent power source comprises a wind turbine, a solar cell, a marine power system, or any combination thereof;
determine power demand of subsea equipment based on the input data;
operate a switch to enable power flow from the intermittent power source to the subsea equipment as a primary source of power for the subsea equipment; and
operate the switch to enable additional power flow from a steady power source to the subsea equipment in response to determining that the available power is less than the power demand, wherein the steady power source comprises a generator, a power storage, grid power, or any combination thereof.
