Job Description

Roles & Responsibilities

The Senior Renewable & ESS Engineer is responsible for providing specialized technical support for the integration, operational planning, and performance monitoring of Variable Renewable Energy (VRE) and Energy Storage Systems (ESS) within the OETC transmission network. The role supports the development and implementation of dispatch strategies for solar, wind, and battery assets to enhance grid stability, improve renewable energy utilization, and reduce operational constraints. The Senior Engineer analyzes renewable generation forecasts, monitors Battery Energy Storage System (BESS) State-of-Charge (SoC) and performance indicators, and supports the verification of Inverter-Based Resources (IBR) compliance with the technical requirements of the Grid Code and Transmission Security Standards.

Support the daily integration and scheduling of renewable energy resources by performing technical analysis to optimize dispatch and minimize curtailment. Analyze and support the operational strategy for Energy Storage Systems (ESS/BESS), including charging and discharging cycles for peak shaving, frequency response, and system reliability requirements. Assess the performance of forecasting tools for solar and wind generation and recommend improvements to reduce system imbalances. Review Inverter-Based Resource (IBR) technical performance and support compliance verification against Grid Code requirements for fault ride-through, voltage control, and frequency support. Monitor BESS State-of-Charge (SoC), availability, and health indicators to support readiness for critical grid services. Conduct performance analysis of renewable plants, identify deviations from forecasted output, and coordinate with relevant teams on corrective actions. Provide technical input to the Ancillary Services section on the role of BESS in fast frequency response (FFR), operating reserves, and other flexibility services. Participate in the technical review of new renewable and ESS project commissioning requirements to support smooth integration into the LDC dispatch environment. Prepare, review, and update Standard Operating Procedures (SOPs), guidelines, and technical instructions related to VRE and energy storage operations. Share technical knowledge with engineers and operators and support capability building in renewable energy technologies, ESS, and inverter-based power systems.

Knowledge and Understanding of Asset Management, QHSE Management System and IT Security Standard Requirements according to ISO55001, ISO 14001, OHSAS 18001 and ISO 27001 to carry out the assigned duties as per the roles and responsibilities matrix. Undertake additional responsibilities depending on Management and Business requirements.

Desired Candidate Profile

• Bachelor s Degree in Electrical Power Engineering (Master s specializing in Renewable Energy or Power Systems preferred )
• Professional Experience: Minimum of 5 years of experience, in areas of Power System operations, Renewable Energy integration, Energy Storage System or Invertor Based resource management.
