Solar & Wind Curtailment: A Liability or Asset for Grid Decarbonization?
Jun 26, 2019
This discussion dives into the intricacies of renewable energy curtailment, particularly in California, where excess solar power often leads to significant waste. It likens energy curtailment to uneaten leftovers, urging a reevaluation of how we perceive wasted electricity. The conversation shifts toward the potential economic advantages of overbuilding renewable sources instead of relying heavily on storage solutions. Financial implications for renewable developers are explored, highlighting the need for innovative strategies and enhanced infrastructure to handle increasing energy supplies.

Quick takeaways
- Renewable energy curtailment is shifting from being seen as waste to a necessary aspect of efficiently managing surplus generation in grids.
- Building additional renewable capacity, even with some curtailment, is recognized as a financially viable strategy for deep grid decarbonization.
Deep dives
Understanding Renewable Energy Curtailment
Renewable energy curtailment is increasingly viewed not merely as waste but as a consequence of the growing share of solar power in regions like California. The state's solar generation often exceeds demand during sunny periods, leading to significant amounts of electricity being zeroed out. For example, in April 2019, California experienced a curtailment of 190 gigawatt hours, more than double its previous records. This scenario raises questions about how to efficiently manage surplus generation while ensuring a sustainable and economically viable energy grid.
