Energy and utilities
Networks that deliver electricity, water, and essential services.
Utilities combine long-lived infrastructure with an obligation to deliver a reliable service. Generation or treatment, transmission, distribution, and retail billing can sit in one organization or in separate businesses. The regulatory structure determines which prices are negotiated and which returns are allowed.
What to look for
Ask what constrains peak capacity, how costs are recovered, and who pays for new infrastructure. Annual output alone does not show whether a system can meet demand at the right place and time. Oil and gas extraction is classified separately under mining and extraction.
