Recomendaciones

The objective of this project was to investigate the integration of RE for Civmec, specifically by performing a techno-economic assessment of the integration of the RE technologies into Civmec’s operations.

Based on the findings, and in light of the limitations of this project, there are four different system configurations that have been recommended and tested using the HOMER™, RET Screen™, and WAsP™ Climate Analyst software packages. These systems were wind only, PV-only, PV battery, and PV wind battery system, and all systems were analysed using the HOMER™ software. However, a system that consists of PV-only has been recommended for the integration of RE technologies in Civmec.

The PV-only system consists of 2565 solar panels, and inverters that are grid-connected, which has an initial cost of $1,367,886 and is expected to be paid back within 4.2 years. A similar 1MW system has been already used by the Cockburn ARC building. This system also has the lowest initial cost and a reasonable payback period.

That being said, the other three configurations are also economically feasible, although there are safety and economic concerns that decided that in the end, these arrangements are not the best for Civmec, based on the analysis. The safety concern is such that a large battery, especially lithium ion has some heating problems through continuous charge and discharge cycles. Furthermore, Civmec has engineering equipment with high temperatures that could compound the problem should an accident with the battery storage happens. The economic concerns are such initial costs for the other systems being much higher than the PV-only system, and the NPV is best in this system as well. Therefore, the final recommendation is a PV-only system as a result of the Techno-Economic Assessment of RE for CIVMEC.
