127 companies scored with the Regulated Utilities template — moat analysis for regulated monopoly utilities: electric, gas, water, and ipps.
Updated 8 days ago
A regulated utility is a legal monopoly whose prices are set by a regulator rather than by a market. It cannot raise prices at will and it cannot be undercut, so most of the usual questions about competitive advantage barely apply. What matters is the quality of the regulatory bargain: whether the company earns the return it is allowed, funds its capital programme cheaply, and sustains the dividend investors own it for.
The franchise is the moat, granted rather than earned: an exclusive right to serve a territory in exchange for regulated prices and an obligation to supply. Its value depends entirely on how constructive the regulator is — how promptly costs are recovered and how fairly returns are set. A stable, above-peer margin is the financial evidence of a workable regulatory relationship.
A utility earns an allowed return on the capital invested in its network, the rate base. The allowed return is granted; actually earning it is not. Cost overruns, regulatory lag and disallowed spending mean many utilities under-earn their own authorisation, so consistently hitting the allowed return signals both operational control and a constructive regulator.
Utilities are owned largely for income, and the dividend is only as safe as the operating cash flow behind it. Because the sector funds a continuous capital programme, a payout that depends on new borrowing or share issuance is structurally fragile. Cash generation that covers both the capital plan and the distribution is what makes the yield dependable.
Regulated utilities carry more debt than almost any other sector, which suits how predictable their revenue is but makes credit quality a core competitive asset. A downgrade raises the cost of the very borrowing that funds the rate base, compressing returns for years. Comfortable interest cover and moderate leverage protect the whole model.
Efficiency is unusually consequential under regulation. A regulator that sees persistent cost outperformance may let the company keep part of it, while an inefficient operator faces disallowances. Costs held below what the regulator assumed turn into earned return; costs above it come straight out of shareholders.
Electricity, gas and water are bought in a recession at close to the volume bought in an expansion, which is why utility revenue barely tracks the economic cycle. That demand inelasticity is itself the defense: it produces cash flows stable enough to support the leverage, the dividend and the multi-year capital programme that define the sector.
Artesian Resources Corporation (ARTNA), MGE Energy Inc. (MGEE), American States Water Company (AWR) currently hold the widest moats of the 127 companies in the group, led by Artesian Resources Corporation at 79 out of 100. The full ranking is on this page, and each company links through to the six defenses behind its score.

It scores 6 defenses: Regulatory Franchise, Rate-Base Return Quality, Dividend Sustainability, Capital Structure Discipline, Operational Efficiency, Essential Service Resilience. Each is measured independently and then weighted, so a company can be strong on one and weak on another. The weights differ from other templates because the defenses that decide who wins in Regulated Utilities are not the ones that decide it elsewhere.
Across the 127 companies in this group the median moat score is 54, with the middle half falling between 40 and 62. A score above the upper quartile puts a company in the strongest quarter of its industry. Because scores are percentile-based, roughly half of any industry sits below its own median by construction.
