  • Connections Information- Generation and Storage – Transmission reinforcement

    We have seen an unprecedented growth of embedded generation at all voltage levels. This has led to heavy constraints in certain areas of our networks to the extent that your connection may have an impact on the transmission network. Where this occurs, we need to apply to the Transmission System Operator (TSO) on your behalf to find out what impact your connection may have. Your Connection Offer will confirm which process we will use for your connection.
