AI data centers, rising utility rates, and stickier inflation are reshaping how investors think about electricity providers, creating both opportunities and risks for the Utility Sector Stocks screener. SSE (LSE:SSE), a UK-based utility with a market cap of £29.3b, generates electricity from wind, hydro, thermal plants and batteries, and connects around 4 million customers in Great Britain and Ireland. SSE generates most of its revenue from energy trading and optimisation through SSE Energy Markets (£7.5b), alongside contributions from SSE Thermal (£5.1b), Energy Customer Solutions (£4.9b), SSE Renewables (£1.6b), and its UK (£7.9b) and Ireland (£2.2b) networks businesses. SSE gives direct exposure to electricity demand from AI data centers while anchored by regulated UK networks and long term contracted renewables, but its investment case hinges on confidence in long term infrastructure returns and its borrowing-heavy balance sheet. Centrica (LSE:CNA), an integrated energy company behind British Gas with a market cap of £7.7b, generates most of its £22.5b in business revenue from Retail (£16.5b), with additional contributions from Optimisation (£6.1b) and Infrastructure (£2.0b).
