Your mission

Your job responsibilities:

BESS strategy: Developing and refining cost-effective grid connection solutions for own substations / BESS projects. Create an optimal co-location BESS strategy for each of the projects in the pipeline. This would include identifying the optimal size / technology in coordination with the development / land securing team..
Grid connection application: Guide / support the technical team in applying for the grid connections for all the BESS / RES projects. Objective would be to liaison with the DSO / TSO and create an optimal technical solution to achieve maximum Import and Export capacity for all the projects. Review of the GCCs and negotiating with the DSO / TSO would be critical element of the job.
Project Planning and design: Planning and designing the electrical grid infrastructure, such as substations, transfer stations, transformer stations, and cable networks, including the preparation of technical specifications and tender documents. This will also include design of the BESS capacities and identifying the optimal technology / size of the BESS.
