Who Pays for the Infrastructure?

There is no single answer to the question "Who pays for data-center infrastructure?" Different infrastructure components are funded and recovered under different rules.

A data-center developer may directly pay for project-specific facilities, site work, private substations, behind-the-meter generation, or other dedicated equipment. Electric utilities may build new substations, distribution lines, and service extensions, with costs recovered under utility tariffs or other regulatory arrangements. Ohio's AEP data-center tariff was specifically designed to reduce the risk that residential and small-business customers would bear infrastructure costs associated with exceptionally large new loads.

Transmission is different. PJM plans large regional transmission upgrades and allocates many network-upgrade costs under PJM/FERC cost-allocation rules. In a 2026 FERC filing, PJM testimony stated that most transmission network-upgrade costs associated with large loads are not directly assigned to the large-load customer and instead are socialized within or across transmission zones under the existing methodology.

Local infrastructure can add another layer. Roads, water, sewer, emergency services, and related capacity may be funded through developer agreements, utility fees, local-government spending, or combinations of these depending on the project and jurisdiction.

That is why the useful question is not simply "Does the data center pay?" Ask four questions separately: What infrastructure is needed? Who builds it? Who pays initially? And who ultimately bears the cost after utility, regulatory, and public-finance rules are applied?
