Summary
The energy transition and the consequent decarbonization of the Chilean electricity matrix have led to a progressive reduction in systemic inertia, increasing the vulnerability of industrial facilities to power quality disturbances. This paper presents the conceptual engineering development and techno-economic evaluation for the integration of a 5 MW / 15 MWh Battery

Aconcagua.
The study addresses the challenge of implementing resilience solutions in existing facilities, proposing a segregated microgrid architecture that protects critical loads using inverters with
Grid-Forming capability. It details the critical need to perform a technological retrofit on existing boundary circuit breakers to allow for a seamless transition to island mode without supply interruption.
Economically, a valuation methodology based on the Cost of Unserved Energy (CUE) specific to the petrochemical industry is proposed, integrating the "Shadow Value" of avoiding unplanned plant shutdowns (Crash Stops) with revenue streams from energy arbitrage and ancillary services. The results indicate that, under a co-optimized operation strategy, the project achieves a Net Present Value of USD 2.7 million and an Internal Rate of Return of 19.2%, validating that industrial resilience is financially sustainable when operational risk is correctly quantified.
