Regulated vs. Deregulated Electricity in Site Selection

Electricity has become a more consequential factor in industrial projects each year as connected loads rise, available capacity tightens, and decision-makers pay closer attention to how power gets purchased and delivered.

It is important to understand that electric service does not work the same way everywhere. In a regulated market, a utility generates or procures the power and delivers it to the facility, all at commission-approved rates. In a deregulated market, those functions are separated, and the customer selects a competitive supplier for the electricity itself while the delivery utility continues to move it. That distinction determines how electricity is purchased, who the company negotiates with, and where responsibility sits over the life of the facility. It does not, on its own, determine what power will cost.

Site Selection Group, a full-service location advisory, economic incentives, and real estate services firm, evaluates utility structures in both regulated and deregulated markets for clients across a wide range of demand profiles and risk tolerances. The right structure depends on the operation, and identifying that fit is part of every location analysis we run.

1. Market Structure Does Not Predict Your Electricity Cost

Deregulated markets are frequently assumed to offer lower rates because customers can shop for their own supply, but competition affects only a portion of the bill and does not guarantee a lower total delivered cost. Electricity costs still reflect the underlying expense of generating power, securing fuel, transmitting the power, and maintaining the infrastructure that serves the customer. A regulated utility with access to low-cost baseload generation can serve an industrial customer for less than a competitive supplier purchasing into a higher-priced wholesale market, and frequently does.

Each structure creates value differently. Regulated utilities often maintain industrial tariffs, interruptible rates, demand-response programs, and other options built for large users. Deregulated markets allow companies to customize supply contracts, lock in prices, or adjust purchasing strategy as market conditions change.

The practical steps are the same in both cases. Model the bill using the facility's actual load profile, the utility charges that will apply, the programs for which the operation qualifies, and the supply terms on the table. What matters is the total delivered cost for that operation at that site.

2. In a Deregulated Market, You Only Shop Part of the Bill

Retail choice applies to the supply portion of electric service. A competitive supplier sells the electricity. The delivery utility remains responsible for conveying it through the wires, substations, and other infrastructure serving the facility, and those delivery charges stay regulated regardless of which supplier the customer selects.

The division carries more weight for a large industrial user than for a small commercial account. A competitive quote addresses the energy the facility consumes. Distribution and transmission service, along with the riders and surcharges attached to them, arrive on the same bill at rates the customer had no part in negotiating.

Demand charges are frequently among the largest line items on an industrial bill. How much of that cost falls on the supply side versus the delivery side varies by market and by tariff. They also work differently from the rest of the bill: Rather than billing total consumption over the month, they bill the highest rate of draw the facility hits at any point during it, typically measured over a short interval. Two plants can consume the same total electricity and pay very different demand charges if one runs steadily and the other spikes. A supply contract prices the consumption. It does not touch the spike.

The consequence for site selection is that supplier quotes are not comparable across locations. Two facilities with identical load can receive similar supply pricing and still land far apart on total delivered cost. The difference is the delivery territory and the tariff that comes with it. A site comparison built on the shopped portion of the bill measures what the customer controls and ignores what frequently decides the outcome.

3. Procurement Flexibility Varies by Market

Companies with retail choice can structure a purchase several ways: a fixed price for a set term, an indexed contract that follows the wholesale market, or a blended approach that fixes part of the load and leaves the balance exposed. That flexibility creates savings opportunities, and it also creates a set of decisions someone has to own. Contract length, pricing structure, renewal dates, and purchase timing all affect long-term cost. A contract signed when wholesale prices are low can look very different from the same contract signed six months later. Companies also need to understand which charges are fixed, which can change, and which sit outside the supply agreement entirely.

Regulated service asks less of the customer. The utility applies commission-approved rates, provides the power, and sends the bill. The plant manager does not need to become a part-time energy forecaster or decide when to lock in the next contract.

4. The Delivery Utility Controls Capacity and Schedule

The delivery utility controls the studies, engineering, infrastructure upgrades, and construction required to connect the facility. This means a competitive supplier may offer a better price or a more flexible contract but cannot add capacity, build a distribution line or shorten the delivery utility's construction schedule.

More supply options therefore do not make every site in a deregulated market competitive. High delivery charges, limited capacity, costly upgrade requirements, or a long construction timeline will govern the outcome at that site. Utility due diligence still happens at the site level in both market types, and it comes down to whether power is available, what it will cost to deliver, and when the facility can be energized. On projects where schedule drives the decision, the connection timeline will decide the site regardless of what the supply pricing looks like.

5. Market Structure Changes: Who Owns Long-Term Risk

Neither structure eliminates long-term electricity risk. It changes who is responsible for managing it. In a regulated market, cost changes arrive through rate cases, fuel adjustments, and regulatory decisions that sit largely outside the customer's control but demand little of the customer to manage. In a deregulated market, more of that exposure traces back to decisions the company makes itself, including supplier selection, contract timing, renewal strategy, and how much market exposure to accept.

Organizations with a dedicated energy procurement function, or an advisor filling that role, are equipped to manage those decisions. Organizations without one are still making them, just without anyone assigned to the job, which is how a favorable initial contract becomes an unfavorable renewal several years into operations.

Conclusion

Market structure belongs in a site-specific utility evaluation as one input among several. Used as a shortcut for predicting cost or risk, it tends to eliminate viable sites early and advance weaker ones.

The work looks the same in either market. Model the total bill against the actual load profile, confirm capacity and construction schedule, review the rate and contract options available at that specific site, and determine who will manage electricity procurement over the life of the facility. If nobody on the project team can name that person, a deregulated site carries more cost than the supply pricing suggests.
