Senior Operability Analyst

About The Role

Great Britain's electricity system is undergoing an ambitious, exciting, and vital transformation.

Together with industry, we are creating a cleaner, greener system, one that protects the planet and serves generations to come.

The Zero Carbon Operation team is an exciting team in the NESO’s Networks department, playing an important role in determining the operational requirements of the GB electricity system beyond 2025, when it will regularly have no fossil fuelled generation running.

We are developing a strategy to ensure that the electricity system is operable as we rapidly transition towards a fully decarbonised system by 2035.

Further challenges exist to meet the government’s target of a net zero electricity system in 2035.

In a small team you will build upon the existing work across the NESO to identify all future requirements and ensure that the NESO with industry has a plan in place to ensure reliable, efficient and low‑carbon electricity supplies into the future.

The role will report to the manager of the EV & Storage team and will primarily work on the interactions between those two technologies (electric vehicles and electricity storage) and a zero‑carbon electricity system.

The role is likely to also support other related aspects of zero‑carbon system operation, such as understanding the operational requirements of a zero‑carbon system and how various technologies could contribute to these.

The role will include performing quantitative analysis, collaborating with others, developing new ways to understand and explain complex issues, supporting the NESO to make decisions and prioritise efforts, and working with external stakeholders.

The team often has to break new ground in areas without established methods and understanding, so we need flexibility, pragmatism, curiosity and creativity.

Technical scope is broad, deep and complex – you don’t have to understand it all when you join, but you will need to enjoy building that understanding and working with others.

The role is based from Warwick (although Wokingham can be considered) and we continue to offer hybrid working from office and home.

We are open to full‑time and part‑time applicants, as well as flexible working arrangements.

This is a fixed‑term contract to cover maternity leave.

• Key Accountabilities
• Provide insight into the changes affecting the operation of a zero‑carbon electricity system, forming the basis of our strategy, decision making and policy development.
• Focus on the roles of EVs, storage (and flexibility more generally) in a zero‑carbon electricity system, and identify and quantify the specific “system needs” these technologies meet, considering other technologies that could also meet them.
• Use analysis and other methods to better understand and explain the issues.

Prepare content for internal and external presentations and reports, and briefing notes to support internal decision making.

• Work with external stakeholders to improve mutual understanding of the interactions between their needs and the needs of the electricity system.

Essential

• Recognised analytical and coding skills (e. g., Python, Power BI, advanced MS Excel).
• Experience analysing and presenting complex issues to a range of audiences.
• Ability to structure logical arguments and relevant evidence, and to support senior decision makers; strong record of communicating complex ideas and representing the NESO at external meetings.
• Ability to develop novel methods for improving our understanding in areas lacking existing work, and to creatively solve problems with available resources.
• Ability to deliver all parts of a piece of work on your own (technical, planning, administration, review) and to work collaboratively with others on parts of a project.
• Flexibility and agility to manage a wide range of issues simultaneously and to refocus rapidly if priorities change.

Desirable

• Previous experience thriving in unfamiliar, technically complex environments.
• High‑level understanding of at least some parts of the technical and commercial fundamentals of electricity system planning and operation, and of the operation of electricity wholesale and ancillary service markets.
• Good stakeholder engagement capability, including articulation and exploration of complex insights to influence internal and external stakeholders.
• What You’ll Get

A competitive salary of £61,000 – £72,000, dependent on experience and capability.

In addition to your base salary, NESO’s core benefits are the essential perks and advantages that form part of your employee package:

• Bonus based on company performance.
• 26 days annual leave as standard.
• A competitive contributory pension scheme where the company doubles your contribution to a maximum of 12 %.
• Annual enrolment to the NESO Savings Plan – when you save £20–£500 a month from your take‑home pay, the company matches 50 %.

Benefits

• Flexible bank holidays and holiday trading.
• Additional birthday day off.
• Cycle‑to‑work scheme, retail and gym discounts.
• Private medical insurance, critical illness insurance and personal accident insurance.

About Us

At the National Energy System Operator (NESO), we play a vital role in tackling climate change and securing Great Britain's energy future.

We already operate the world's fastest decarbonising electricity system and are working towards our ambition to run it carbon‑free for a short period this year—provided the market supplies electricity exclusively from renewable sources.

We provide expert advice to government on how to deliver a clean power system by 2030.

In autumn 2024, the Electricity System Operator (ESO) transitioned to become NESO, an independent, expert public corporation with a whole‑system view across electricity, gas, and hydrogen.

Licensed and regulated by Ofgem, we make impartial decisions that balance sustainability, affordability and security.

NESO recognises the potential of bright and talented individuals and encourages you to join us as Great Britain’s energy system undergoes an ambitious, exciting, and vital transformation.
