Public Service Enterprise Group Incorporated PEG

Company Overview

Public Service Enterprise Group Incorporated (PEG), commonly known as PSEG, is a publicly traded energy company primarily engaged in regulated electric and natural gas utility operations and nuclear power generation in the United States. The company operates at the intersection of the electric utilities, natural gas utilities, and energy infrastructure industries, with revenues predominantly driven by regulated utility services and long-term generation assets. PSEG’s business model emphasizes stable, regulated earnings complemented by selective ownership of generation assets with long-term contracts or regulatory support.

Founded in 1903, PSEG has evolved from a regional electric provider into one of the largest utility-focused energy companies in the northeastern United States. Over time, the company transitioned away from competitive merchant power generation and refocused its strategy on regulated utility operations and nuclear generation. This strategic shift culminated in the divestiture of most fossil fuel generation assets in the early 2020s, reinforcing PSEG’s positioning around grid reliability, decarbonization, and regulated infrastructure investment.
