Grid regulation and infrastructure
Treatment of RES dispatch (curtailment)
RES technologies like PV and wind provide a fluctuating source of electricity, this means that the grid has a higher chance of being overloaded. In order to safely exploit the grid and to reduce the costs associated with grid congestion, DSOs ask for more flexibility from electricity producers, typically by writing up contracts with RES project developers granting them access to the grid on the condition that they can be curtailed without any compensation in return.
As these terms are decided at the end of the permit delivering process, the developer has no choice, but to accept the conditions. This, along with the increasing grid access prices, makes the profitability of the RES plant questionable and uncertain.
This online database provides information on barriers and best practices for wind onshore, wind offshore, PV rooftop and PV ground-mounted technologies.
