National Grid
We power the lives of millions of people across Britain, New York and Massachusetts, moving energy from where it’s made to the communities that need it, every single day. In the UK, people connect with the electricity they need to live, work, build and play through our cables and wires. And in the US, we deliver electricity and gas to families and businesses in the states we call home. We're leading the way to a new energy era, building and operating the next generation of networks to unleash the energy needed to meet accelerating demand. With our very own venture capital fund, we’re challenging ourselves and our sector to work faster, smarter, and with an unrelenting focus on solving the challenges of the day for our customers. Our 30,000 employees live and work in the communities we’re proud to serve. Creating positive legacies matters to us; we do the right thing. And through our work, we’re creating enduring benefits for a better world where people can thrive.
