Company overview

NATIONAL GRID USA

National Grid USA keeps the lights on and gas flowing for millions of households, municipalities, and businesses across the Northeast, operating as an integrated electric and natural gas delivery system rooted in the regulated utility landscape defined by SIC 4911/4924; the company builds and maintains transmission and distribution networks, modernizes grid controls, and invests in resilience projects so that residential, commercial, and industrial customers can rely on uninterrupted service even as electrification and sustainability trends reshape demand. With CIK 71297, it still navigates the complex web of state public utility commissions, the Federal Energy Regulatory Commission, and environmental safeguards that monitor capital spending, reliability metrics, and climate-related disclosures, making regulatory compliance and storm-response preparedness material risks alongside cyber and supply-chain pressures.
