Key Responsibilities
Performance Analysis & KPI Tracking
- Lead the monitoring, performance analysis, and operational reporting for a portfolio of distributed generation standalone BESS and paired solar + storage assets.
- Establish, calculate, and track critical BESS KPIs, including Round-Trip Efficiency (RTE), State of Health (SOH), auxiliary power consumption, availability, and State of Charge (SOC) management.
- Conduct complex degradation modeling and build predictive analytics to forecast battery life, track SOH trajectories against capacity guarantees, and optimize charging and discharging cycles.
- Extract, clean, and analyze large-scale SCADA and telemetry datasets to troubleshoot underperforming systems and diagnose component failures.
- Partner with Data Scientists to integrate BESS telemetry with enterprise platforms, structure data storage, and automate internal and external reporting pipelines.
- Leverage Generative AI tools and LLMs to accelerate code development, automate data processing workflows, and streamline complex analytics.
- Model and evaluate performance impacts during transitions between standalone BESS and AC/DC-coupled BESS + PV configurations.
- Present operational findings, performance metrics, and recommended corrective actions or dispatch strategies to both technical and non-technical stakeholders.
