The Constraints Reports below present the results of analysis for a range of study years and generation scenarios indicating estimated future levels of oversupply, curtailment and constraint for controllable solar and wind generation connected at distribution and transmission level. 

These reports are being issued to fulfil the requirement of the CRU’s ECP-2 decision, CRU/20/060, that the TSO carry out system studies and publish regional constraints reports to inform generators about possible solar and wind generation reduction levels.

The generation reduction values calculated are subject to the study assumptions which are described in detail in the report. The study scenarios only cover those renewable generators up to and including ECP2.1.
