We are at the heart of one of the greatest challenges facing our society – delivering clean energy to support our world long into the future.

And we are proud that our work, and our people, underpin the prosperity and wellbeing of our customers, communities and investors.

 National Grid (LSE: NG; NYSE:NGG) is an electricity and gas company that  connects consumers to energy sources through its networks.

Cables in tunnelThe company is at the heart of one of the greatest challenges facing our society – to create new, sustainable energy solutions for the future and developing an energy system that underpins economic prosperity in the 21st century. National Grid holds a vital position at the centre of the energy system and it ‘joins everything up’.

In the northeast US, we connect more than seven million gas and electric customers to vital energy sources, essential for our modern lifestyles. In Great Britain, we run the gas and electricity systems that our society is built on, delivering gas and electricity across the country.

National Grid delivers electricity to approximately 3.4 million customers in Massachusetts, New York and Rhode Island. We own over 4,000 megawatts of contracted electricity generation, providing power to over one million LIPA customers. We are the largest distributor of natural gas in the northeast US, serving approximately 3.6 million customers in New York, Massachusetts and Rhode Island.

The electricity industry connects generation sources to homes and businesses via transmission and distribution networks. Electricity is sold to consumers by companies who have bought it from the generators and pay to use the networks across which it is transmitted.

The gas industry connects producers, processors, storage, transmission and distribution network operators, as well as suppliers to industrial, commercial and domestic users.

What we believe

At National Grid we encourage everyone to respect others and value their diversity. To take ownership for driving performance. And to always be open and act with integrity in all relationships. Living these values makes sure we work as one team, one National Grid. Especially as collaboration is the norm.

It's vital that everyone contributes. After all, energy is essential to every community, the challenges never let up and the pace can be intense. On top of all that, we're determined to cement our reputation as a responsible, sustainable business and an industry leader. So we look for innovation and we expect high performance.

In return, we enhance the skills and capabilities of our people in a host of innovative ways. We help them excel in everything from health and safety to inclusion and diversity, from tackling climate change to delivering customer service. And we're big on recognition, rewarding those whose performance sets the standard we all strive for. At the same time, we know a healthy balance between work and life outside it benefits us all.

The result is an organisation full of people who respect, value and support each other while always challenging themselves to achieve more. People who are equipped to make the most of all the career opportunities we offer. Our diverse teams are packed with experience and expertise, and are proud to have safety as their number one priority.

    Positive Experience
    Average Interview


    I applied through an employee referral. The process took 2+ weeks. I interviewed at National Grid USA (Waltham, MA) in April 2016.


    A set of pre-determined questions from HR about past experiences and office ethics. The interviewer also asked their own questions. For the most part it was a relaxed conversation. I was interviewed by two people, the hiring manager and an engineer who worked for him. I made sure to answer questions to both of them instead of just to the person who asked.

    Interview Questions

    • What would you do in a situation where you knew someone was saying something incorrect in a meeting.   Answer Question


    I made several requests for a signing bonus, relocation money, and compensation for turning down healthcare. They are all denied. The salary I was being offered was slightly higher than I expected so I still took the offer.
