WHO ARE ILOS?

ILOS is a fast-growing renewable energy company with a strong presence across Europe, backed by BNP Paribas IM Alts and committed to accelerating the energy transition. Since 2018, we have developed, built, and operated large-scale solar PV projects across seven core markets.

THE ROLE OVERVIEW

The BESS Manager will play a key role in building and commercialising ILOS’ battery storage pipeline across Europe. The position sits between development, finance, technical and external market stakeholders, ensuring storage projects are structured around robust revenue models, bankable commercial frameworks and well-managed contractual arrangements.

This is a commercially focused role supporting projects from mid-development through to financial close and into early operations, helping translate technical storage assets into investable and revenue-generating projects. A core part of the role is strong financial and revenue modelling capability for BESS projects, including both standalone and co-located configurations, to support investment decisions and route-to-market strategy.

TASKS

• Lead the commercial workstream for BESS projects, shaping revenue strategy and the route-to-market approach for various BESS assets.
• Assess and model storage revenue opportunities such as merchant markets, ancillary services and contracted structures.
• Support offtake and optimisation discussions with traders, utilities and flexibility providers.
• Contribute to business case development, financial model inputs and investment approval materials.
• Support procurement and negotiation of key commercial contracts linked to BESS projects, including optimisation, tolling or service agreements.
• Work closely with technical and grid teams to ensure commercial assumptions align with system capability and connection constraints.
• Identify and manage key commercial risks, supporting mitigation strategies within project structures.
• Monitor market developments, regulation and revenue mechanisms across target European markets.

PROFILE

• Experience in a commercial, market- or structuring role within energy, storage, renewables or power trading.
• Good understanding of electricity markets, flexibility services and how storage assets generate value.
• Exposure to project-financed infrastructure or renewable energy projects is advantageous.
• Comfortable working across functions (technical, finance, legal, development) in a project-driven environment.
• Confident building and assessing financial models for standalone vs co-located BESS projects.
• Strong analytical and commercial mindset, able to link market dynamics to project-level decisions.
• Confident stakeholder manager, able to engage with optimisers, utilities, advisors and internal teams.
• Structured, proactive and comfortable operating in a growing business entering a new technology segment.
