Using liquid fuels to produce electricity for any other use than backup/emergency is not very efficient. The best source for electricity would be the dried biomass, sans seeds. ( ~16.8 million Btu per ton, 3 + tons per acre, 4,650 + kWh per acre). Heat would be the useable byproduct of the gasification (CHP - Continual Heat & Power).
Other alternative for the biomass is to implement pyrolytic conversion to manufacture methanol. That would amount to ~186 gallons of methanol per ton, or ~568 + gallons per acre. US DOE releases dated 1995 state a manufacturing cost of $0.20 a liter, with expectations of reducing those costs to ~$0.13 a liter. There literally is no other plant, save for perhaps algae (still in experimental stages), that can produce the same amount of biomass per acre in the same 90-120 day time period.
