# Nisource Moat

Status: published. Policy: company-analysis-1.

NiSource has a narrow moat in its established utility delivery infrastructure, supported by regulated investment recovery and continued transportation service when customers choose alternative gas suppliers. Pricing power is constrained: cost pass-through protects recovery, while regulators determine rates and permitted returns. Electrification, regulatory disallowances and capital-intensive expansion could erode the advantage. Data-center development represents potential growth rather than demonstrated additional moat.

Established utility delivery infrastructure retains a role even when customers purchase gas competitively: disclosed customer-choice programs use NiSource subsidiaries for transportation. Regulation supports recovery of prudent infrastructure investment and a reasonable return. Together these support a narrow incumbent delivery advantage, although the passages do not establish exclusive franchises or quantify duplication barriers.

Durability: Existing transportation arrangements and approved infrastructure recovery programs support persistence. Durability depends on continued network demand and favorable regulatory treatment; exceptional or guaranteed protection is not established.

Risks: Gas supply itself is competitive. Heat pumps, alternative fuels and restrictions on natural gas could reduce network utilization. Regulators can limit recovery and returns. New data-center commitments introduce construction, financing and demand risks rather than proving stronger incumbent economics.

Invalidation: The thesis would fail if supplier choice materially displaced NiSource transportation, sustained fuel substitution stranded delivery investment, or regulatory decisions repeatedly prevented recovery of prudent costs and a reasonable return. Loss of eligibility for regulated accounting would be a particularly clear warning.
