How we're organised
On this page, you will find a high-level organisation chart for the System Operator (SO) as well as an explanation of each of the major units within the SO business. As the SO, we must look across both gas and electricity to better understand the rapidly-changing energy environment. Therefore we have created a few dual fuel roles to ensure that we have a view across the whole energy system.
This table outlines the SO operating model and senior leadership appointments.

*SO roles work across both electricity and gas
The Strategy and Regulation team plays a lead role in informing and developing the future direction of the System Operator (SO), both gas and electricity, to ensure the long-term success of the business. Their function anticipates how the industry will evolve and shapes the role that the SO should play in the industry. The Strategy and Regulation function delivers strategic value for stakeholders, customers, and shareholders.
In line with legal separation requirements, they work with the regulator and set the long-term regulatory strategy on behalf of the ESO. The Strategy and Regulation function owns the customer strategy for the SO, setting out the strategy for how customers are managed, driving customer insights and understanding customer relationships across multiple touchpoints.
The Future Markets department works with existing and potential market participants, regulatory bodies, and other stakeholders to analyse the suitability of gas and electricity market frameworks. The department also develops new gas and electricity frameworks when necessary.
Overall, Future Markets plays a key role in the development of EU and GB legislative, regulatory, and commercial policies and codes.
The National Control (ESO) department is responsible for the development and delivery of the short-term plan, and operating the electricity network in real-time to deliver world-class levels of service to customers and stakeholders in a safe and efficient manner.
The Commercial (ESO) department is working to improve the procurement of balancing services for our consumers by predicting changes in operations, creating secondary services that provide a range of balancing options to the control room. These will also improve the Transmission Owners' (TOs') access to the network.
All of this is underpinned by an analytics function that models system characteristics in order to provide short- and long-term advice to guide procurement decisions within the Commercial and National Control departments.
Commercial also has a specialised team which maintains the delivery of the Electricity Market Reform (EMR) on behalf of the government, administering the Capacity Market and Contracts for Difference procurement schemes. Finally, Commercial is responsible for the revenue collection and settlement activity of the Transmission Network and Balancing Services Use of System charges (TNUoS and BSUoS) and connection contracts.
Networks (ESO) is responsible for the development of the strategy, direction, and design of the near- and long-term electricity network capability across the UK. The department ensures improvements in the system and aims to deliver world-class levels of service for customers and stakeholders.
The Gas Operations (GO) department is responsible for the real-time operation and control of the gas National Transmission System (NTS) in Great Britain (GB), and for facilitating efficient operation of the GB gas market. We operate the NTS in line with our Primary Gas Transporter Safety Case ensuring that pressure within the NTS is maintained within safe limits and that the quality of the gas we transport is compliant with the Gas Safety Management Regulations (GSMR).
GO delivers value for customers by providing the transmission capacity and flexibility when it is safe to do so, and provides them with critical information and data to allow them to make effective and efficient decisions for their businesses.
GO plays a key role in ensuring that National Grid can deliver value from our gas transmission incentive schemes, which are designed to ensure we make the right risk-reward based decisions on behalf of customers, minimise our environmental impact, and optimise the utilisation of the NTS.
The GO function is organised into four departments delivering: real-time control, optimisation of the network and commercial strategies, performance against incentives and commercial obligations, and the development of the processes and systems needed both now and in the future.
