Commercial Graduate Scheme - Data Science

Join us, and help be the energy behind the change.

National Gas is the backbone of Britain's energy system. We're responsible for securing the UK's energy, whilst leading the way to a net-zero future.

 
As the operator of Britain’s national gas transmission network, we repair and maintain gas pipelines, safely and reliably delivering gas to power stations, industries and 23 million homes. 

Our skilled teams work to keep the gas flowing to our customers, generating power and helping to keep everyone connected.

 
At the same time, we’re pioneering new solutions like hydrogen transmission to help decarbonise energy, so our infrastructure continues to power the country as it transitions to net-zero.

 
As a graduate joining National Gas, it’s an inspiring environment where you know your work will directly contribute to keeping the nation’s energy secure today, whilst building a more sustainable, net-zero energy system for tomorrow.

About the Role

Joining our Commercial function within the Energy Systems & Resilience team, you'll have an amazing opportunity to work alongside experts, who every day, are developing plans for the future. This division covers a breadth of work, so you can expect to use your data science and modelling skills across a range of commercial subject area. As a graduate, your work will be full of variety. You might be engaging with the government, collaborating internally and externally on report submissions, working with real time operations, liaising with stakeholders and communities or perhaps developing new styles of modelling and analysis to bring to life National Gas’s performance narrative.

Our teams partner with subject matter experts across the business to deliver upon our commercial objectives and regulatory commitments. We engage with external stakeholders such as Ofgem and Government to shape future regulatory frameworks – for our (existing) methane and (future) hydrogen and carbon dioxide transportation networks. Your work could involve assessing and improving operational performance, supporting research into policy and practice, supporting external consultation and engagement and inputting into specific project programmes. We are currently working on a number of high-profile net zero projects including hydrogen and CCUS as well as ensuring we deliver secure and affordable energy to households and business up and down the country.

During this 18-month programme, after your initial induction, you’ll complete three 6-month placements. This will cover various teams within the Commercial business function, so that you can be exposed to different, yet relevant experiences and skillsets that will set you up for your career. These include: 

•    System Operations
•    Markets
•    Innovation
•    Regulation
•    Customer, stakeholder and business development

With the contacts you’ll make and the skills you’ll learn in these areas, you’ll be able to make an informed decision as to which area of the business you’d like to continue your career in. Upon completion of the programme, graduates will typically progress into roles such as Data Scientist, Analyst, or Commercial Analyst.
