Iberian solar ancillary services participation lifts revenues up to 35%

Solar assets in the Iberian zone that participate in ancillary services are likely to achieve revenues up to 35% higher than those sitting out of those markets, according to Aurora Energy Research. The analysis points to ancillary services as a material upside lever for existing and new-build solar in Spain and Portugal, where curtailment pressure and low capture prices have squeezed energy-only returns in recent years.

Aurora has not detailed which ancillary products drive the uplift in the published headline, but the 35% figure covers participation broadly across ancillary service categories in the Iberian zone. Asset owners and offtakers structuring PPAs or merchant exposure in Iberia should treat the figure as an upper bound for the revenue stack available to fully grid-service-capable assets.

In a separate development, Gülermak closed £30m in financing from mBank for five Polish solar assets with combined capacity of 62.7 MW, per Renews.biz.
