Combining solar or wind farms with large-scale battery storage at a single site, known as co-location, is gaining traction. The approach offers multiple advantages, from diversifying revenue streams and reducing market risk to mitigating price cannibalisation and enabling generation or grid feed-in during high-value evening hours.

The economic efficiency of battery storage can be improved through cost savings from a shared grid connection point and faster access to the grid. Benefits for the electricity system include reduced grid bottlenecks, fewer feed-in restrictions for plants and more effective use of limited grid capacity.
Expert analysis: Key challenges and opportunities for the European renewable energy market
The biggest barrier to wider market uptake remains regulation. But signs of progress are emerging, as a handful of European countries begin to adapt their frameworks to support co-located systems.
