By asset type
Hybrid plants (generation + battery)
Combining generation and a battery at the same connection point multiplies the revenue levers: you do not just sell energy, you also decide when.
When output exceeds the export limit, the battery charges instead of losing that energy to curtailment.
The battery adds aFRR, mFRR, technical constraints and arbitrage on your own capacity.
Smooths out intermittency and allows a more predictable profile to be offered.
What is included
Illustrative example of a day · 15 MWh exported + 6 MWh of surplus
Sells 15 MWh at €55/MWh (€825) and loses 6 MWh because of the export limit, with no compensation.
Sells the same 15 MWh (€825), charges the 6 MWh surplus into the battery and sells it at the peak at €100/MWh (€600).

Hybridisation and ancillary services
How much a solar plant's price can improve
Average price each solar MWh earns depending on how much of the output a battery shifts to the 4 priciest hours of the day (Spanish day-ahead market).
Downward ancillary services
Renewable portfolios already offer secondary regulation band during solar hours, when the market price is low. The revenue per MW depends on the regulation zone and the plant's enablement, and we calculate it with system operator data in the revenue study. Source: Modo Energy ↗
