How solar IPPs hybridise: Lessons for solar-plus-storage design and operation, with Sonnedix

As the energy transition accelerates, solar + BESS hybrid projects are rapidly becoming the new standard. But while many developers approach these systems with a "solar mindset," battery storage introduces a fundamentally different layer of operational complexity, one that directly impacts performance, revenue, and long-term asset value.

In this webinar, industry experts from Sonnedix and TWAICE explore how to design and operate solar + BESS projects that are not only optimized for today's requirements, but resilient and profitable in tomorrow's markets.

We begin by addressing a critical shift: BESS is not a static asset like PV, it is a stateful, constraint-driven system, where real performance depends on dynamic factors such as temperature, degradation, availability, and control logic, not just nameplate capacity. When combined with solar, this complexity increases further, introducing shared bottlenecks, headroom conflicts, and plant-level coordination challenges at the point of interconnection.

From there, we dive into one of the most underestimated strategic decisions in hybrid projects: the Energy Management System (EMS). Moving from standalone solar to hybrid systems fundamentally changes the EMS role. From simple optimisation to real-time orchestration of competing objectives (market participation, SoC management, grid compliance, and asset protection).

We also explore the growing importance of advanced BESS analytics as a critical enabler for performance optimisation and risk mitigation. Raw data alone is not enough, operators need to translate telemetry into actionable insights: identifying hidden capacity losses, detecting early-stage failures (e.g., imbalance, weak cells, thermal issues), and building audit-ready evidence for warranty and performance claims.

Finally, we zoom out to a broader industry trend: the evolution of the BESS value chain, where system integrators are becoming the central players. As accountability becomes increasingly fragmented across OEMs, EPCs, and operators, understanding how to manage performance, risk, and responsibility across stakeholders is now essential.
