National Grid (NG.L) Stock Analysis & Winston Score

National Grid owns and operates the electricity and gas networks that move energy from power plants to homes, businesses, and hospitals. It does not generate electricity itself — it runs the "pipes and wires" infrastructure that other energy companies use to deliver power. National Grid is one of the largest energy transmission and distribution companies in the UK and the northeastern United States. The company earns money through regulated fees set by government bodies, meaning its revenue is largely predictable but capped by regulators in both the UK and the US. This regulated model provides stability but limits how much profit National Grid can earn. The company is currently investing heavily in upgrading its electricity networks to handle more renewable energy, which requires billions in capital spending — the key risk is that this debt-funded investment could strain its balance sheet if interest rates stay high or if regulators do not allow sufficient fee increases to cover costs.
