System Operator definition

What does System Operator mean? In energy and utilities practice, “system operator” describes the entity that runs an electricity or gas transmission system in real time, balancing supply and demand, issuing dispatch instructions, managing constraints and outages, and maintaining security of supply. The term is widely used in licences, industry codes and regulatory practice rather than as a single universal statutory definition; related defined terms such as “transmission system operator (TSO)” appear in UK and Irish legislation and EU‑derived rules.

Practice notes

ARCHIVED:

This Practice Note is archived and is not being actively maintained.

Tomlin orders in England and Wales: CPR guidance on drafting, confidentiality, approval, variation, enforcement, limitation, CCA issues, court-specific requirements, sample wording and precedents

This Practice Note This Practice Note reviews mechanisms used in settling litigation. A Tomlin order consists of a consent order paired with a schedule. It operates to stay proceedings on terms that have been agreed. The provisions contained in the schedule may remain confidential. This Practice Note describes the scope of confidentiality attaching to the schedule and sets out how it differs from a standard consent order. Sample wording for a Tomlin order is included, alongside links to precedents, as well as guidance on court approval. It also addresses varying, setting aside and enforcing a Tomlin order, including the considerations the court will take into account when handling applications for each. Further guidance is provided on interpreting and applying the relevant provisions of the CPR; however, some courts and divisions impose very specific requirements for both drafting and approval, and for approaching the schedule and confidentiality issues. Accordingly, you must consider the particular rules and court guide provisions in the forum where your claim is proceeding when drawing up the Tomlin order...
