Title:  Senior Business Analyst - NESO

About the Role

This Senior Business Analyst role will work within a small team within the Regulatory programme. The Industry Codes Business Analyst team at NESO focuses on shaping and interpreting changes to the industry codes and regulatory frameworks to ensure compliance, enable market evolution, and support strategic alignment with energy regulations.

The role primarily delivers strategic pre-project business analysis supporting the wider NESO position within the industry code modification process for proposed regulatory changes.

The role would also support more detailed inflight-project business analysis where code modifications progress to delivery within the Regulatory programme.

The area of focus is on modifications to the Technical and Commercial Codes which have the potential for DD&T impacts. Work in this area involves close stakeholder engagement with the Market Frameworks team, operational Subject Matter Experts (SMEs) and product teams within the affected platforms.

The role will involve working within a context of uncertainty, due to the general nature of early-stage analysis and the specific evolving nature of each modification which is subject to industry decisions.

As a Senior Business Analyst role, this also involves leading and managing more junior analysts in the team.

This role is based in the Wokingham office, with hybrid working from office and home. The Business Analyst (BA) team working on GB regulatory changes attend the Wokingham office one day per week as a group, usually on Mondays. 

Key Accountabilities

• Work with Market Frameworks to define an analysis approach for the high level discovery and impact assessment which is appropriate to the timing, scale and the stakeholders involved with the assigned code modification
• To build and maintain alignment between the Market Frameworks code lead, operational SMEs and impacted platform SMEs on DD&T matters arising from the code modification
• Work with stakeholders to carry out an initial high-level analysis enabling appropriate next steps. Choose appropriate analytical tools to define a high-level definition of the problem(s) arising from the code modification, resulting NESO needs, impacted platforms and provide an initial view of the necessary change if the code modification is to be implemented
• Carry out further discovery and impact assessment analysis if necessary to refine NESO’s position on the code modification as the modification develops, to understand the entire perspective of the change including the time and cost implications of the modification’s implementation
• Clearly articulate the impact of proposed changes on NESO and the wider industry to support the development of NESO’s external position on the proposal
• Perform more detailed analysis within regulatory projects which progress into delivery stages if the code modification is approved, such as eliciting more detailed levels of requirements, business models and options analysis
• Lead and manage more junior analysts within the team where more than one BA is assigned to a project
• Knowledge sharing and participation within the Industry Codes BA team and the wider Regulatory programme on progress with analysis, raise awareness of any blockers and any findings which may benefit other teams

About You

• Ability to create and maintain alignment with diverse groups of stakeholders on uncertain and evolving changes which are driven by industry decisions
• Technical BA skills to analyse problem situations and help others to understand the impacts to their processes, systems and data, and document the conclusions

About The National Energy System Operator (NESO)

In Autumn of 2024, the ESO transitioned to National Energy System Operator, or NESO for short. Previously denoted as the Future System Operator (or FSO), the new National Energy System Operator is the independent body responsible for planning Great Britain’s electricity and gas networks and operating the electricity system.

The ESO, including all of its existing roles, are now at the heart of the new National Energy System Operator. As NESO, we will build on our existing roles, capabilities, and ways of working significantly to create an organisation the energy system and its users’ need. Our new capabilities will enable us to look across vectors, including electricity, natural gas and hydrogen, and crucially consider the trade-offs between them.

The organisation is set up as a public corporation with its own Board of independent directors, with complete operational independence from government, the regulator and any and all commercial interest. As was the ESO, NESO will be licenced and regulated by Ofgem through price control agreements and obligated to identify optimal solutions to system operations and planning in the most sustainable, affordable and secure way for all.
