We hold these events four times a year and consider these as key milestones to engage with a wide range of industry stakeholders. We aim to reflect on the priorities of the energy industry and how the ESO role, and in turn Markets, is positioned to deliver against these.  

Our Market priorities are structured into how the Market is operating now, how we are developing the Market and how we are designing our Markets fit for the future.


  • We will use these engagements to communicate on our strategy, decisions and policy positions
  • Explain the products and services we are developing now and designing for the future
  • For transparency, hold space for discussions and provide updates on industry blockers and opportunities
  • Signpost to how we are facilitating co-creation on how we develop, design and implement our market solutions

Timeline for the next Markets Forums

Following the Markets Forum we hosted in November 2023, we have taken on board your feedback and we are pleased to announce that we plan to hold the Markets Forum four times a year. Two of these events will be virtual pre-recorded webinars with a live Q&A webinar a week later. Sli.do will be open from the point of the webinar release date. The next two will be in person with the facility to livestream the main presentation. The dates of the events can be found below.

Markets Forum - March 2024

We are pleased to bring you the first Markets Forum event of 2024. Having listened to your feedback about accessibility to our forums and the time commitment required, we have agreed to annually hold two pre-recorded events, and two in person where the main presentation will be live streamed. 

Our intent is to keep the messages at these forums focused on the things that matter to you. We aim to keep messages at a holistic level, communicated in a way that does not require expertise, and to also signpost how you can get more involved in specific topics. 

To kick off the new format, we have published a recorded webinar and a set of videos on the Markets Roadmap chapters. This was also followed up with a live Q&A session. The links to the content can be found below.

Markets Roadmap - March 2024

In March we also launched our annual Markets Roadmap, so we have a separate set of videos that cover a summary of the Roadmap and a brief overview of the chapters, which you can watch below.

Introduction and overview  An introduction and overview of the new Roadmap.
Balancing Mechanism  The Balancing Mechanism (BM) is the market we use to ensure that energy supply and demand are balanced and to manage system operability issues in real-time.
Response  Frequency response services react in real-time to automatically balance supply and demand and maintain frequency on the grid.
Reserve  Reserve is the capability to deliver upward or downward energy to manage pre-fault imbalances and post-fault losses of generation or demand.
Stability  Stability is the inherent ability of the system to quickly return to acceptable operation following a disturbance.
Thermal   Thermal constraints refer to an area of the network where the physical infrastructure is overheating due to too much electricity overloading the network.
Voltage Voltage is the ‘push’ that causes electrons to move in an electrical conductor, measured in volts. 
Restoration  Restoration refers to the process of restarting the grid following a National Power Outage.
