Impact of Negative Prices on Solar Operations
Negative pricing in the Iberian renewable energy market significantly affects solar asset management, as it can lead to financial losses for producers. With over 120 gigawatts of renewable capacity expected for connection, many plants are now generating power far from demand centers, creating challenges for profitability. Efficient forecasting and smarter operational strategies have become crucial as solar operators navigate these market conditions, seeking to optimize revenue and adapt to increasing curtailment. The need for improved financial planning, better coordination with grid management, and enhanced digital systems has been emphasized to ensure asset resilience.
