About Astatine
Astatine Limited is a specialised energy company focused on accelerating the transition to zero carbon for energy users across multiple sectors. We design, construct, operate, and maintain multi-technology assets, including solar PV, battery energy storage, heat pumps, and advanced controls. Our core values are collaboration, innovation, urgency, and integrity. As the energy sector grows rapidly, interns will have the opportunity to upskill in cutting-edge technologies and gain exposure to real-world engineering projects.
About the Team
The Proposals Team acts as the bridge between Business Development and Engineering, supporting clients from early-stage opportunity to project development and handover for detailed design.
About the Role
Working alongside experienced engineers and commercial professionals, the successful candidate will assist in energy modelling, developing feasibility assessments, preparing proposals, tender submissions and building business cases for industrial energy projects.
This role provides exposure to a broad range of technologies including heat pumps, solar PV, battery energy storage systems (BESS) & many more.
Key Responsibilities
- Support the development of technical and commercial proposals for industrial decarbonisation projects.
- Analyse client utility and process data to identify energy-saving and carbon reduction opportunities.
- Assist with energy modelling and feasibility assessments for heat, power, and renewable energy projects.
- Support the sizing and high-level evaluation of technologies such as heat pumps, solar PV, thermal storage, and battery storage systems.
- Develop preliminary energy, carbon, and financial analyses to support investment decisions.
- Understand available and applicable grant funding opportunities, including SEAI and other national and European funding mechanisms.
- Assist with tender responses, budget estimates, and proposal documentation.
- Prepare technical reports, presentations, and client-facing materials.
- Work with Business Development teams to understand client objectives and translate these into proposed technical solutions.
- Support the transition of projects from concept and proposal stage to the engineering design team, ensuring clear communication of project scope, assumptions, and objectives.
Skills & Experience
- Currently pursuing a degree in Energy Engineering, Mechanical Engineering, Electrical Engineering, Sustainability, or a related discipline.
- Strong analytical and problem-solving skills.
- Proficiency in Microsoft Excel; Word, Powerpoint.
- Ability to interpret technical and commercial data.
- Strong written and verbal communication skills.
- Interest in industrial energy systems, sustainability, and decarbonisation.
What You’ll Learn from this Internship
- Exposure to a wide range of industrial clients and an understanding of how energy systems operate within their facilities.
- Feasibility assessment and techno-economic evaluation.
- Energy and carbon modelling.
- Grant funding and incentive schemes.
- Preparation of client proposals and tender submissions – technical documents.
- Commercial aspects of delivering decarbonisation projects.
- How projects progress from initial client engagement through concept development and into detailed engineering design.
