Power Grid Analyst - 6 month FTC

Octopus Energy Group is an energy tech company. We use technology to make green electrons cheap and revolutionise customer experiences.

By combining world‑class tech with brilliant humans who care deeply about customers and driving the renewable energy transition, we made it happen and in 2025, we became Britain’s largest energy supplier.

Now, we’re scaling fast and building the next generation of products to accelerate the green energy transition. From making it effortless to switch to heat pumps, solar and EVs, to launching smart tariffs and creating renewable generation at scale, we’re solving some of the most complex challenges in energy with speed, creativity and customer obsession. We’re also enabling our global businesses to reach the full capability of what we’ve achieved in the UK, taking the learnings, products and experiences that customers love here and rolling them out worldwide.

What you’ll do

• Grid assessment: Map, analyse and model grids across various markets. Analyse and provide insights to inform capex strategy, prioritising non‑wire solutions.
• Techno‑economic and electrical power flow modelling to define optimal mix of resources against specific objectives (grid constraints, peak profile, LOLE, LCOE etc.)
• Technical assessment of solutions for grid quality and stability issues, with a focus on non‑wire solutions (flexibility and BESS).
• Grid development plans: support the team in reviewing and designing grid investment plans or Integrated Resource Plans, for technical sign‑off.
• Interconnection: Analyse grid constraints and provide insights on grid connection queues.

What you’ll need

• Strong background in energy systems. Or an educational background in electrical engineering or power system modeling
• Advanced power flow modelling expertise (PSCAD, PSSE, PowerFactory, PandaPower) and knowledge of non‑linear optimisation. Ability to run or develop deterministic physics based grid modelling tools.
• Knowledge of linear, economic modelling, e.g. plexos, is a plus. Experience with DERs, medium and high voltage grids and utility‑scale energy projects.
• Deep understanding of energy economics and grid infrastructure principles, enjoys generating insights from large and complex sets of energy data and metrics.
• Enjoys starting things from scratch, pro‑actively look (and find) data, and iterating quickly. Natural curiosity and passion for all things grid and the energy transition.

Data platform stack

• Python as our main programming language.
• Databricks as our data lake platform.
• Kubernetes for data services and task orchestration.
• Terraform for infrastructure.
• Streamlit for data applications.
• Airflow purely for job scheduling and tracking.
• Circle CI for continuous deployment.
• Parquet and Delta file formats on S3 for data lake storage.
• Spark for data processing.
• DBT for data modelling.
• SparkSQL for analytics.
