Battery project scope and investment size
PPC Renewables Romania plans to install a 40.08 MW/80.16 MWh battery at its Corugea wind farm, creating a two-hour storage system. The project is described as being designed to improve the commercial and grid performance of the existing renewable asset. The investment is estimated at approximately €17.6 million, equivalent to about €220,000 per MWh of storage capacity.
Funding is expected to come from around €2 million through the EU Modernisation Fund, which is just over 11% of the total. PPC financing will cover the remaining amount.
Connection details and generation profile
The battery will be connected to the 70 MW Corugea wind farm near Casimcea in southeastern Romania. The wind project comprises 35 wind turbines and produces approximately 190,000 MWh annually. PPC estimates a capacity factor close to 31% for the plant.
PPC estimates that the wind farm supplies the equivalent of more than 70,000 households and avoids over 130,000 tonnes of carbon dioxide emissions each year.
Role of storage in market participation
Adding storage is intended to enable the wind farm to shift part of its output into higher-value hours. It is also described as supporting management of short-term forecast errors and reducing exposure to imbalance costs. The battery power rating is set at approximately 57% of the wind farm’s installed capacity.
PPC says this configuration provides flexibility without attempting to store the project’s full output.
Modernisation Fund selection and expansion plans
The battery project has been selected under Romania’s Modernisation Fund programme for battery systems connected to operational renewable plants. The support structure directs capital towards hybridisation rather than standalone storage, linking public funding to assets with an existing generation profile and grid connection.
PPC Renewables is seeking to expand its Romanian renewable portfolio towards 2 GW. Corugea is presented as a repeatable model for upgrading existing wind projects through storage without requiring an entirely new generation development.
Revenue sources and bankability considerations
The investment case is based on multiple revenue sources including energy shifting, balancing participation, reduced imbalance exposure and improved control over delivery during constrained periods. Its bankability will depend on how these revenues are contracted. It will also depend on whether the battery’s operating strategy can preserve capacity while capturing Romania’s widening hourly price spreads .
