-Grid operators hold mandates to manage the technical functioning and long-term adequacy of electricity networks at transmission, distribution, or local level. Smart grid transitions expand what they coordinate: bidirectional flows, distributed storage, and advanced metering data require new capabilities and coordination architectures.+This topic is part of the ISGAN Wiki and is currently being developed.

 ===== Why this matters ===== ===== Why this matters =====
  
-The operator mandate was designed for centralised generation and passive demand. Smart grid transitions change what operating a grid means — requiring coordination of resources that are dispersed, often unpredictable, and controlled by actors outside the operator's direct authority. Distribution system operators are increasingly expected to procure flexibility and coordinate behind-the-meter resources in ways their licensing and revenue frameworks were not designed to cover.<sup>1</sup>+[To be drafted]

-In most jurisdictions, the regulatory authorisation for these expanded operator functions is still being defined.+[To be drafted]

 ===== A shared definition ===== ===== A shared definition =====
  
-An operator is an entity with a mandate or licence to manage the technical functioning, stability, and adequacy of part of an electricity system. System operation may be separated from asset ownership under unbundling rules, and a single entity may fulfil several roles depending on local regulatory design.+[To be drafted]
  
-^ Category ^ Scope and typical mandate ^ +See also: [[topics:network_-_grid|Networks & Grids]] for the distinction between grid architecture and grid operation.
-| Transmission system operator | High-voltage network; frequency control, cross-border capacity, long-term grid planning | +
-| Distribution system operator | Medium- and low-voltage networks; local reliability, voltage management, connection of distributed resources | +
-| Microgrid operator | Defined local perimeter; islanding capability, local balancing, coordination with the main grid |+

 ==== Actors and stakeholders ==== ==== Actors and stakeholders ====
  
-Grid operators interact with generators, retailers, balancing parties, and end users. Ownership and operation of grid assets are often separated, and the clarity of role definitions between entities shapes how investment decisions are made. Distribution system operators face a particular challenge as growing numbers of small-scale actors collectively shape local grid conditions. +[To be drafted]

-**South Korea — KEPCO:** Generation, transmission, and distribution under one vertically integrated entity, contrasting with unbundled arrangements elsewhere.<sup>2</sup> +

-**Germany — regional DSOs:** Over 800 distribution system operators manage local grids, making coordination across the distribution layer a distinct governance challenge.<sup>3</sup>+
  
 ==== Technologies and infrastructure ==== ==== Technologies and infrastructure ====
  
-Operators rely on SCADA, energy management systems, and distributed energy resource management platforms. As resources multiply at the grid edge, operators need real-time visibility into low-voltage networks and the ability to process data at scale. Effective integration requires interoperability across technical, informational, and organisational levels — as described in the GridWise Architecture Council framework.<sup>4</sup>+[To be drafted]

-==== Institutional structures ====+===== Key terms =====
  
-Licensing conditions specify reliability standards, reporting obligations, and revenue frameworks. In jurisdictions transitioning toward smart grids, regulators face a recurring question of whether and how to expand distribution operator responsibilities to include active system management and flexibility procurement.+^ Term ^ Definition ^

-**Nigeria — Transmission Company of Nigeria:** TCN manages the national grid while eleven distribution companies handle regional delivery — a separation that creates coordination challenges at the transmission-distribution boundary.+**Operability and interoperability.** [To be drafted] See [[topics:operability|Operability]] cross-reference note: interoperability concerns the ability of components and systems to exchange meaningful information; operability concerns how the system as a whole performs its functions in real time. These are related but distinct. [To be drafted]
  
-</WRAP>+**Operability and grid architecture.** Architectural frameworks such as SGAM and SGIRM define the structural layers and interfaces of the grid; operability addresses how that structure performs under real operating conditions.
