Which entity is responsible for ensuring that any changes to a system are communicated to the relevant parties?

The Transmission Operator is responsible for ensuring that any changes to a system are communicated to the relevant parties. This role involves overseeing the transmission of electrical power across the grid and ensuring that all operational changes, such as updates to transmission lines, grid configurations, or maintenance schedules, are effectively communicated to affected stakeholders. This communication is crucial because it ensures that all parties involved in the electricity supply chain, including generation facilities, distribution systems, and market participants, are aware of any modifications that could impact system reliability, operational efficiency, or market operations.

The responsibilities of the Transmission Operator are aligned with the need for coordination in maintaining the reliability of the power system and supporting compliance with regulatory standards. The continuous flow of accurate information allows for effective planning and response to any operational challenges the grid may face, thereby sustaining stability in the electric system. Other entities like the System Operator or Regulatory Authority play significant roles as well, but the primary focus on direct system changes and stakeholder communication inherently falls under the Transmission Operator's purview.
