Thin film, silicon, concentrated solar power (CSP), concentrated photovoltaics (CPV), ... These are just some of the terms demonstrating that solar technologies are rapidly entering the electricity system in countries such as the United States, Spain or Australia. Furthermore, the largest improvements, which will bring generation cost closer to competitive prices are just around the corner.
This webinar is dedicated to utility scale and baseload solar technologies: CSP and CPV.
What is the status of these technologies, their improvement potential and perspectives for the future? What are the running projects and expectations in terms of market development? How is the levelized energy price expected to evolve in the near future to reach grid parity? Additionally, more practical aspects will be presented, as the conditions required by a CSP project to be viable or the keys to successfully finance the project.
After this briefing presentation, a discussion with participants will be launched on questions such as storage capabilities and system operation. Other questions from attendees are welcome to guide the discussion.
