Overview of the Role
Overall, how would you describe your experience at National Energy System Operator?
Overall, I really have enjoyed my time here. The company has a great environment to be yourself and develop professionally.
What are the main responsibilities of the role and which elements of the role do you enjoy the most?
My main responsibilities are to provide analysis, forecasts and strategies for the control to plan day ahead. I enjoy being able to see that my work provides a real difference to the operations of the control room and to GB.
To what extent does your role give you the opportunity to contribute meaningfully and feel valued by your team?
5/5
My manager has given me work that affects the team and the business, I get to see how my analysis is helping and I have a very supportive team to help me do this.
How does your compensation package - including perks & benefits - fairly remunerate you for the work you do?
4/5
We get given a lot of responsibility and objectives, which is great for our development, but also doesn't reflect in benefits between real members of staff and graduates.
How well do you feel the role is preparing you for your future career?
5/5
Really great that we get to move around, network ad feel comfortable in the corporate environment. The skills that I am learning will be used throughout my career.
How would you rate the extent to which you were developing new or existing skills through formal training and your day-to-day role?
4/5
I am developing a lot of new skills through my day to day role and any training I seek out to do, which is amazing and has been so beneficial. However, it would be more beneficial having official and consistent graduate training throughout the scheme.
