Level up. How storage can boost return on investment in renewable energy

As the share of wind and solar in the electricity mix continues to rise at an unprecedented speed, growth pains of curtailments and low capture prices are felt throughout the industry. At the same time, batteries are now following into the footsteps and steep S-curves of wind and solar to take us one level up in the energy transition. This panel will share insight how storage - hydro-pumped and batteries can each add value to renewable assets.

Renewable Energy Industry in Southeast Europe 2024 report by SeeNext

As Southeast Europe (SEE) has made breakthrough progress in greening the power supply in recent years with unprecedented growth in installed capacity, it is now tasked with the next challenge - how to balance supply and demand, and how to advance the installation of new capacities but also guarantee the stability of grid infrastructure when these capacities come. Energy storage solutions and grid modernisation are the two main components in tackling such challenges. To find out more for the RES Industry in SEE, download the report here.
