Paul Industries designs and installs cleaning and process heating systems across New Mexico, the state with the cheapest industrial electricity in the United States at 5.43 cents per kilowatt-hour, 0.67 times the national average. That single figure reopens a decision most plants made decades ago and never revisited: whether process heat should come from a gas-fired boiler at all. In most of the country electric process heating loses on running cost before the conversation starts. In New Mexico it is a genuine comparison.

Where electric heat wins, and where it does not
The honest version of this comparison is that electricity price is necessary but not sufficient. Cheap power makes electric heating viable; whether it is correct depends on the shape of the demand.
Electric heating is strongest on intermittent, modest and dispersed loads. A cleaning cycle that runs for ninety minutes and then stops is exactly the profile a fired boiler serves badly, because the boiler has to be kept available, cycles inefficiently, and loses heat through standby and distribution whether or not anything is drawing. An electric heater draws only when heating, converts essentially all of it into heat at the point of use, and has no standby loss. On a plant whose thermal demand is a few cycles a day, that difference is substantial.
Electric heating also removes a set of costs that never appear in a fuel comparison. No combustion air, no flue, no gas train, no burner management, no boiler inspection regime, no combustion-related permitting, and no fuel supply infrastructure to the point of use. On a small or dispersed installation those can exceed the equipment cost.
Fired heat still wins on large continuous demand. A plant with a substantial, steady thermal load will generally find that the fuel price advantage of gas, even against New Mexico electricity, outweighs the efficiency and infrastructure advantages, and that the electrical supply capacity required for a large electric load is itself a significant cost.
The useful conclusion for a New Mexico plant is that the answer is load-shaped rather than universal, and that the default assumption, which is fired heat because that is what plants have, deserves to be tested. We have seen small and medium cleaning installations here where electric heating was clearly correct and was never considered, because the question was settled before anyone looked at the tariff.
Comparing honestly
| Factor | Favors electric | Favors fired |
|---|---|---|
| Demand pattern | Intermittent, cyclic | Large and continuous |
| Scale | Modest or dispersed loads | High aggregate duty |
| Conversion | Near unity at the point of use | Losses in combustion and distribution |
| Standby loss | None | Real and continuous |
| Ancillary systems | None required | Flue, combustion air, gas train, burner management |
| Infrastructure cost | Electrical capacity, which can be large | Fuel supply, which is usually present |
| Control | Fine and immediate | Coarser, with lag |
| Cycle profile, 300 a year | New Mexico | US average | Massachusetts |
|---|---|---|---|
| 40 kW for 1 hour | $652 | $976 | $2,183 |
| 80 kW for 90 minutes | $1,955 | $2,927 | $6,548 |
| 150 kW for 2 hours | $4,887 | $7,317 | $16,371 |
Those columns are the argument. A cleaning system that would be an energy conversation in Massachusetts is close to a rounding error in New Mexico, which means cycle design here should be optimized for the thing that actually costs money, which is production time, and not for the energy the cycle consumes.
What cheap power does not change
It is worth being clear about the limits, because a cheap-energy argument can be stretched past where it holds.
It does not make a longer cycle acceptable. The cost of a cleaning cycle in a working plant is mostly the capacity it consumes, and that is unaffected by the tariff. A cycle that takes two hours instead of ninety minutes costs the same lost production in New Mexico as anywhere.
It does not justify heating instead of solving a coverage problem. A vessel that needs a repeat cycle because spray coverage is shadowed is not fixed by cheap heat; it is fixed by getting solution to the surface. Cheap energy makes the symptom affordable, which is precisely why the underlying fault tends to survive longer here.
And it does not change cleaning validation. What residue has to be removed, how the limit is justified and how removal is demonstrated are unaffected by what the heating costs. Those questions are answered the same way in every state.
The right way to use the advantage is to spend it on robustness: adequate heating capacity so cycles are not extended waiting for temperature, generous hot water provision so the plant does not run short mid-shift, and continuous rather than intermittent operation where continuous operation is technically better. Cheap power in New Mexico should buy a better-behaved plant, not a lazier one.
Frequently asked questions
Do you install cleaning and process heating systems in New Mexico?
Yes, across Albuquerque, Rio Rancho, Las Cruces and statewide: CIP skids and distribution, parts cleaning, process heating whether electric or fired, hot water systems, instrumentation and controls. On New Mexico projects we test the electric against fired assumption rather than inheriting it.
Is electric process heat really competitive here?
On the right load shape, yes. At 5.43 cents per kilowatt-hour, the lowest industrial rate in the continental US, electric heating is genuinely competitive for intermittent, modest and dispersed loads, where it converts nearly everything at the point of use and has no standby loss. On large continuous duty, fired heat generally still wins.
What costs does electric heating avoid?
Combustion air, flue, gas train, burner management, boiler inspection regime, combustion-related permitting and fuel supply infrastructure to the point of use. On a small or dispersed installation those can exceed the equipment cost, and they rarely appear in a comparison that only looks at fuel price per unit of energy.
When should we stay with fired heat?
Where the thermal load is large and continuous. There the fuel price advantage generally outweighs the efficiency and infrastructure benefits, and the electrical supply capacity a large electric load requires becomes a significant cost of its own. The comparison is about load shape rather than about a universal answer.
Does cheap power justify a longer cleaning cycle?
No. The dominant cost of a cycle in a working plant is the capacity it consumes, and that is identical in every state. A cycle taking two hours instead of ninety minutes costs the same production in New Mexico as in Massachusetts. Cheap energy should buy robustness, not a slower plant.
Can cheap heat compensate for poor spray coverage?
It can hide it, which is worse. A vessel needing a repeat cycle because coverage is shadowed behind an agitator is not fixed by more affordable heat, and cheap energy makes the symptom tolerable enough that the underlying fault survives longer here than elsewhere. Verify coverage with an indicator test rather than trusting the datasheet.
Does the tariff change cleaning validation?
Not at all. What residue must be removed, how the acceptance limit is justified and how removal is demonstrated are the same questions in every state. Energy affects how you heat and how you size, not what you have to prove or how you prove it.
How should we use the advantage?
On robustness. Adequate heating capacity so cycles are not extended waiting for temperature, hot water provision generous enough that the plant does not run short mid-shift, and continuous operation where continuous is technically better than intermittent. Those are the decisions cheap power makes affordable that would be argued about elsewhere.
Is the rate likely to stay this low?
We would not build a business case that depends on it staying exactly where it is, and neither should you. The 5.43 cents figure is EIA’s 2024 industrial average for the state. Use it for the decision at hand and test the comparison against a higher rate to see whether the conclusion survives, because a conclusion that only holds at the current tariff is fragile.
How do I get a quote for a New Mexico project?
Use the form on this page or call 201-450-8280. Useful inputs are your thermal demand and its shape across a day, the vessels and circuits involved, what heating exists today and its condition, your electrical supply capacity and what headroom it has, and your actual gas and electricity tariffs rather than state averages.
How does electric heating change CIP system design?
Electric heating suits smaller, distributed heaters at the point of use rather than a central boiler with distribution losses, and it responds quickly, which suits intermittent cleaning demand. The design shifts from a steam header to local heaters with storage sized to the cycle.
Does a heat pump make sense for CIP water in New Mexico?
Cheap electricity makes resistance heating competitive; a heat pump makes it cheaper still where the plant has a cooling load or warm waste stream to draw from. In a plant with refrigeration, heat pump water heating for CIP is usually the lowest running cost option available.
What about hard and brackish water in cleaning systems?
Much of New Mexico's water carries high dissolved solids that scale heaters and leave residue on rinsed surfaces. Softening or reverse osmosis on the cleaning water supply protects heat exchange surfaces and keeps rinse quality where the validation put it.
How is water scarcity reflected in cleaning design here?
Rinse water is recovered into pre-rinses, chemistry is recovered and reused, and cycle lengths are set by conductivity endpoints rather than timers. The water saving from those measures is usually larger than the energy saving, even at low electricity prices.
Do you design cleaning systems for research and laboratory facilities in New Mexico?
Yes. Laboratory glassware and equipment washing, and cleaning for pilot-scale process equipment, follow the same principles at smaller scale with a stronger emphasis on flexibility and documentation for a range of uses.
How does altitude affect cleaning in New Mexico?
Much of the state sits a mile or more above sea level, where water boils several degrees below 212 degrees Fahrenheit, so hot-water sanitization targets and steam cycles have to be set against the local boiling point and controlled on temperature rather than gauge pressure.
Should CIP heating be scheduled to match solar generation?
Where the plant has on-site solar, heating water into insulated storage during peak generation and cleaning later uses power that would otherwise be exported. It suits plants with a daily cleaning window and enough storage volume.
What should a heating comparison for a New Mexico plant include beyond the energy price?
Boiler efficiency and standby losses, flue and permit costs, maintenance, the demand charge structure for electric, the installed cost of each option, and the plant's expected operating hours. A comparison that stops at fuel price per unit of heat gets the wrong answer in both directions.
Does electrification change the plant's demand charge?
Yes. Large resistance heaters raise peak demand, and the demand charge can erase the energy saving. Storage and controlled heating rates keep the peak down, and the tariff structure is part of the design calculation.
What cleaning chemistry works at lower temperatures?
Enzyme and surfactant formulations clean protein and fat at temperatures well below conventional caustic cycles. They reduce heating demand at any energy price, and in a water-scarce state the shorter, cooler rinses they permit matter as much as the energy.
Can cheap power justify hot-water sanitization over chemical sanitizing?
Sometimes. Hot-water sanitization avoids chemical residue and disposal, and where power is cheap the heating cost is small. The constraint is achieving the temperature at every surface, which coverage testing has to prove.
How is cleaning effluent handled where there is no municipal treatment?
Plants on their own treatment or evaporation systems have to account for cleaning chemistry and volume in the water balance. Chemistry choice and rinse recovery are part of the effluent design, not separate from it.
What instrumentation does an electrified CIP system need?
Temperature at the heater outlet and at the far end of the circuit, power monitoring on the heaters so that energy per cycle is known, and conductivity for rinse endpoints. Knowing energy per cycle is what lets the plant prove the electrification case.
How are cleaning and process heating systems integrated on one project?
By designing the hot water or steam generation to serve both duties from one plant, sizing storage for the combined peak, and controlling the two draws so that a cleaning cycle does not starve the process. Integration cuts capital and standby losses, and it only works when both loads are designed together.
What is the first thing to check before electrifying process heat here?
The load profile. Steady, continuous heating loads favour a boiler or a heat pump; intermittent loads like cleaning favour electric heating into storage. The tariff and the load shape decide the answer more than the average electricity price does.
