Battery Storage as an Integral Part of PV and Wind Projects

Battery Storage in Hybrid Projects — Insights from the 8.2 Network

Battery energy storage systems are increasingly integrated into PV and wind projects. Across Multiple Markets, Engineers from 8.2 Member Offices have contributed to the technical design and economic feasibility assessment of such systems.

Recent projects in Southeast Europe — supported by 8.2 Zagreb d.o.o. and others — illustrate recurring patterns: Early system-oriented design and market-specific feasibility analysis are critical for robust project decisions.

Key insights from these projects:

Hybrid systems require consideration of grid constraints, regulatory frameworks and operational interaction from the outset. The real challenges lie not in individual components, but in their integration.

Economic feasibility depends on local market conditions — real price curves, regulatory context and realistic operational assumptions — not generic models. PV-coupled storage, wind-coupled storage or hybrid systems with limited grid access follow different economic logics.

Quality in BESS projects is established long before construction begins. Early-stage electrical and civil main design defines the basis for permitting, due diligence, financing and later project decisions. Methodology and clear assumptions matter more than speed.

This experience — drawn from multiple projects and markets — forms part of the collective expertise within the 8.2 network.
