Tenders have focused the industry’s attentions on cutting levelised cost of energy (LCOE), told Windpower TV at the Global Wind Summit in Hamburg.
They also offer visibility to investors and developers and this is "positive", Tardieu added.
A provision in the European Union’s Renewable Energy Directive calling for five years’ visibility on tender mechanisms beyond 2020 should be adopted by individual Member States, he added – but legislators can still do more to adapt markets to integrate more renewables.
"We need to make sure that when there is curtailment of renewables, wind is curtailed last," Tardieu told Windpower TV.
"(We need to make sure that) there is transparency on curtailment and redispatch, and also on must-run obligations for conventional power plants."
He added that there also needs to be "much more" regional cooperation between transmission system operators (TSOs) on system management, and more discussion about what to do with inflexible or polluting generation.
