Business Model
What each company does and how it makes money
WEC Energy Group is a regulated electric and natural gas utility serving customers across multiple Midwestern states. It generates revenue primarily through regulated utility operations — electricity generation and distribution (~70%) and natural gas distribution (~30%) — with rates approved by state commissions. Its key advantage is its regulated monopoly status in its service territories, providing stable cash flows through cost recovery and a reasonable return on invested capital.
National Grid is a regulated utility that operates electricity and gas transmission and distribution networks in the UK and northeastern United States. It earns revenue through regulated asset returns — collecting fees from customers for using its infrastructure — with its UK transmission business contributing roughly 40% of operating profit and its US operations about 35%. The company's primary moat comes from its natural monopoly position as an owner of critical energy infrastructure, protected by high regulatory barriers to entry and long-term, stable rate-of-return frameworks.
