How Storage can Change the Returns of a Solar Asset

This session examines how a utility-scale solar project retrofitted or built with co-located battery storage to address curtailment, price cannibalisation, and grid constraints performs. The focus is on what changed financially and operationally once storage was added, and what the asset owner would do differently today.

• Why storage was added?
• Curtailment exposure, capture price erosion, or grid compliance requirements
• How the revenue stack changed: Energy shifting, ancillary services, downside protection, and volatility reduction
• Capital and performance outcomes: Capex uplift, IRR impact, payback period, and lessons for future hybrid projects
