Electric deregulation — sometimes called “retail choice” or “restructuring” — is often presented as a simple proposition: allow customers to shop for electricity, introduce competition, and let the market produce better prices and more choices. In practice, deregulation is more complicated. It changes who supplies electricity, how generation costs are recovered, and how the financial risks of maintaining a reliable electric system are distributed.

A specific responsibility

Under Indiana’s regulated structure, electric utilities have defined service territories and are responsible for generating or procuring electricity, delivering it to customers, maintaining the grid, and planning for future demand. The basic principle is that the utility serving an area has both the obligation and responsibility to serve customers there.

Retail choice changes part of that relationship. Customers may purchase electricity from a competitive supplier while continuing to rely on the incumbent utility for transmission and distribution. The poles, wires, substations, and other infrastructure remain in place. Retail choice changes the generation supplier; it does not eliminate dependence on the local electric system.

States with some form of retail choice include Connecticut, Delaware, Illinois, Maine, Maryland, Massachusetts, Michigan, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, and Texas. Programs vary significantly, with some allowing broad participation and others imposing limits.

Accommodating large-load customers

Limited deregulation is particularly relevant to large-load customers such as data centers and major industrial facilities. Supporters argue these customers should be able to negotiate directly with competitive suppliers and potentially obtain lower prices.

That is also where significant concerns arise.

Large-load customers can represent enormous electricity demand and substantial revenue that support long-term generation, transmission, and distribution investments. If they purchase power elsewhere while continuing to depend on the broader electric system, the costs incurred to serve them may be left behind and ultimately passed on to other customers.

Indiana already has mechanisms — including special contracts, power purchase agreements, integrated resource planning, and alternative regulatory approaches — to accommodate large customers within the regulated framework.

The debate should not begin and end with whether a data center or manufacturer might obtain a lower price. The more important question is who bears the costs and risks left behind. Before Indiana changes a system built around long-term planning, shared infrastructure, and an obligation to serve, policymakers should carefully examine what retail choice has meant elsewhere —
and who ultimately paid the price.
