Curtailment during midday oversupply was destroying the project's economics under a merchant model.
Independent power producer · Extremadura, Spain · 2024
A 12 MWp farm with grid-forming storage
Utility-scale generation with 8 MWh of storage providing firming and network services.
Engineering design
12 MWp single-axis tracked array with 8 MWh of grid-forming storage, dispatched against day-ahead and intraday prices with a curtailment-avoidance controller.
Installation
Ten months from notice to proceed to first energy.
“Storage turned a marginal merchant project into a bankable one.”
