Abstract

The challenges in shrimp cultivation are the intensive electricity consumptions with associated greenhouse gases emissions, security of power supply, and environmental impact from the discharged waste water. Following Thailand energy roadmap, the renewable energy share in power production sector is targeted to be increased, for energy security and climate change mitigation.

This paper evaluates six different scenarios of renewable energy implementation for shrimp farm in Thailand. The results show that the system with solar PV has higher reliability compared to the one with wind turbine at equal life cycle cost. The reliability of the system with solar PV and solar PV with battery varies significantly with the life cycle cost at low cost range then becomes stable.

On the other hand, it was found to be quite stable in the cases of wind turbine with and without battery. Adding battery to the system significantly increases the reliability of solar PV and slightly increases for wind turbine. At the life cycle cost lower than $1 million, maximum reliability of the system with solar PV is around 53%. By adding battery, the reliability of the system can be up to 90%.

The different magnitudes of the reliability between these two scenarios are higher at higher life cycle cost. For this case study, to reach higher than 50% reliability, the recommended renewable alternative is solar PV with battery.
