The CRU “PR5 Regulatory Framework, Incentives and Reporting” Decision Paper (CRU/20/154), published in December 2020, introduced a regulatory incentive on joint TSO/DSO co-ordination. This incentive should ensure that EirGrid as the Transmission System Operator (TSO) and ESB Networks as the Distribution System Operator (DSO) can help each other in achieving their targets or delivering their plans.
