National Grid describes its focus as building a smarter, stronger, cleaner energy future by transforming its electricity and natural gas networks with more reliable and resilient energy solutions to help meet state climate goals and reduce greenhouse gas emissions.
In addition to its US networks, National Grid owns and operates the high-voltage electricity transmission network in England and Wales and the UK's largest electricity distribution network, as referenced in its communications and in third-party descriptions. The company has also stated that it lies at the heart of a transforming energy system, moving energy from where it is made to homes and businesses across the UK and US.

Core business and regulated networks
National Grid’s core activities are regulated electricity and gas networks. Its own materials highlight electricity and natural gas delivery in New York and Massachusetts, and high-voltage electricity transmission and large-scale electricity distribution in the UK. The company reports that it invests heavily in its networks to maintain reliability and resilience, enable economic growth, and support the energy transition.
National Grid’s filings and releases describe significant capital investment plans over a multi‑year period to upgrade and expand its infrastructure. The company reports major investment in UK electricity transmission projects, including Accelerated Strategic Transmission Investment (ASTI) projects, and in US networks such as advanced metering infrastructure and leak‑prone pipe replacement in its gas networks. It also notes that a large proportion of its planned investment has associated regulatory approvals in the US.
Energy transition and clean energy focus
Across multiple press releases, National Grid emphasizes its role in the energy transition. It states that it is transforming its networks with smarter, cleaner, and more resilient energy solutions to reduce greenhouse gas emissions and meet climate goals in its US jurisdictions. The company also highlights work on grid modernization and resilience in both the US and UK, including initiatives to support distributed energy resources and virtual power plant (VPP) participation at selected facilities.
National Grid Partners, the company’s venture investment and innovation arm, is described as investing in startups and technologies that can accelerate the energy transition and help National Grid’s business units. Examples include investments in AI‑powered energy forecasting and analytics platforms and collaborations with companies providing virtual power plant software. National Grid has also participated in offshore wind development through joint ventures referenced in public communications.
Technology, AI, and grid resilience
Recent announcements show National Grid working with technology partners to apply advanced data and AI to its operations. In one initiative, the company is collaborating with a climate resilience planning platform to deploy AI technology that identifies and helps prevent wildfire risks across its electric transmission and distribution networks in Massachusetts, New York, and the United Kingdom. The implementation is described as enabling National Grid to identify high‑risk areas, quantify and prioritize wildfire risks, develop cost‑effective prevention and response strategies, and enhance overall grid resilience planning.
National Grid has also announced a strategic relationship with a virtual power plant platform to expand grid services at selected office facilities in Massachusetts, building on earlier work in New York. Through this collaboration, the company’s buildings participate in state grid services programs that lower electricity usage during periods of grid strain, supporting grid reliability and climate objectives. In addition, National Grid has agreed to implement a cloud‑based customer service and billing platform to improve customer experience, increase operational efficiency, and support the delivery of new energy solutions and pricing plans using smart meter data.

The company presents this as part of a year‑round commitment to local communities.
National Grid and its joint ventures have also supported initiatives to expand access to STEM education and clean energy workforce pathways.
