MANUFACTURING SITE SELECTION • UTILITY EVIDENCE
Utility Due Diligence for Manufacturing Site Selection
Establish what service a site can receive, under which conditions, at what cost and on whose delivery schedule.
A useful review connects the operating requirements with provider evidence, infrastructure work, agreements and the decisions that depend on them.

What should utility due diligence establish?
Utility due diligence for manufacturing site selection tests whether the proposed operation can receive the services it needs and identifies the work, conditions and exposure behind that conclusion.
Technical fit
Capacity and service characteristics must match the actual process, equipment and supporting systems.
Delivery feasibility
Studies, infrastructure, approvals, access and equipment must fit a coordinated project schedule.
Commercial conditions
Understand upgrade funding, ongoing rates, responsibilities, agreement conditions and future requirements.
The output should be an evidence register, remaining-work list, cost assumptions and decision conditions. Connect it with the utility readiness guide to track how investigation leads to usable service.
Start industrial utility analysis with a useful request pack
Give providers and technical advisers a common project definition. A request based only on acreage or building area leaves important operating requirements unanswered.
- Project and location: candidate property, proposed process, relevant contacts and site layout.
- Equipment and operation: major loads, operating cycles, shifts, startup behavior and supporting systems.
- Initial service: electrical profile, water needs, wastewater characteristics, gas requirements and connectivity.
- Timing: construction access, equipment installation, testing, production milestones and later phases.
- Continuity: process tolerance, maintenance requirements, recovery needs and proposed backup arrangements.
- Growth: additional lines, higher loads, expanded shifts and the assumptions behind future demand.
Attach the data basis and identify estimates awaiting design confirmation. Use the same version for each candidate and update the providers when a material assumption changes.
Keep electrical load, demand and energy distinct
Connected equipment
Equipment ratings describe what is installed. Their sum does not establish the maximum simultaneous demand.
Demand profile
Assess how loads operate together, including startup, production cycles, supporting systems and relevant peak conditions.
Energy use
Estimate electricity consumed over a period and when it is used. Energy and demand affect different parts of the service and cost review.
Have qualified electrical specialists define service voltage, configuration, equipment interfaces, power-quality considerations and the reliability design. Ask the provider to evaluate that profile and the planned phases.
Document the study assumptions, required network work, available service characteristics and unresolved technical questions. A previous occupant’s connection does not by itself validate a different manufacturing process.
Use a service-by-service evidence matrix
Record what the project requires, which provider or authority is responsible, what evidence supports the response and what remains conditional.
| Service | Project information | Anzufordernde Nachweise | Conditions to resolve |
|---|---|---|---|
| Electricity | Demand profile, voltage, reliability needs and phased growth. | Provider studies, connection scope, service milestones, proposed rates and responsibilities. | Network work, equipment, approvals, easements, costs and acceptance. |
| Water | Process and cooling demand, pressure, quality and fire-protection requirements. | Provider findings, connection design, supply conditions and required improvements. | Treatment, storage, seasonal conditions, upgrades and delivery scope. |
| Wastewater | Flows, variability, constituents and process changes. | Receiving-authority review, collection and treatment findings, applicable limits and authorization path. | Pretreatment, monitoring, discharge conditions, fees and approvals. |
| Natural gas | Process heat, demand pattern, pressure and service needs. | Provider capacity and pressure findings, extension scope and proposed service terms. | Equipment, land access, costs, interruption conditions and delivery timing. |
| Connectivity | Required endpoints, bandwidth, latency, availability and recovery. | Provider feasibility, physical route information, deployment scope and acceptance criteria. | Shared routes, construction, access agreements and activation dates. |
Keep source documents with the register. Identify the date, geographic scope, validity conditions and responsible reviewer so that a broad availability statement is not mistaken for a project-specific conclusion.
Distinguish levels of provider evidence
Inquiry feedback
Initial discussions help identify the relevant provider, available information and the studies needed next.
Study findings
Review the defined load, scope, assumptions, constraints, upgrade requirements and remaining uncertainties.
Documented commitments
Review the actual agreements, funding, responsibilities, conditions and dates with the appropriate advisers.
Delivered and verified service
Track construction, testing and acceptance against the service the process needs.
Read a letter or proposal for what it actually confirms. Ask whether any capacity is reserved, for how long, under what conditions and what still needs approval or agreement.
A signed document can still contain delivery dependencies. Keep them visible in the working register and distinguish the evidence needed for the current decision from the later conditions needed to operate.
Test wastewater acceptance as well as water supply
Water supply conditions
Review volume, pressure, quality, seasonal conditions, fire-protection needs and the work required to serve the proposed process.
Flow and pollutant loading
Characterize wastewater volumes and constituents, including variability. Hydraulic capacity and treatment suitability are separate questions.
Discharge and treatment requirements
Confirm pretreatment, monitoring, authorization and operating conditions with the receiving authority and qualified environmental advisers.
EPA’s pretreatment local-limits guidance explains how requirements reflect the needs of the receiving treatment works and its system. Confirm applicable requirements for the actual waste streams rather than relying on a statement that sewer service is nearby.
Consider the effects of a changed product, cleaning method or expansion phase. Process changes should be reviewed before assuming that an earlier service assessment remains sufficient.
Review reliability against the process tolerance
Define what interruptions, voltage disturbances, pressure changes or loss of connectivity would mean for production, equipment, quality and recovery. The review should be led by the relevant technical specialists.
Shared dependencies
Investigate whether apparently separate feeds, connections or routes depend on common infrastructure.
Backup and recovery
Validate the proposed response, activation, fuel or other supplies, maintenance and the conditions for returning to operation.
Operating evidence
Request relevant service information and review limitations, maintenance arrangements and escalation contacts.
Apply the actual equipment requirements in EV manufacturing and semiconductor location evaluations. A redundancy label alone does not establish the level of continuity a particular process needs.
Connect utility work with land access and the launch schedule
Physical and approval dependencies
Identify connection points, corridors, easements, rights of entry, permits, road crossings and the design interfaces between provider work and customer work.
Confirm who is responsible for obtaining access and approvals, and which conditions affect procurement or construction.
Integrated delivery milestones
Track studies, agreements, design, long-lead equipment, construction, testing and acceptance against installation, commissioning and production.
Show the work that can overlap and the prerequisites that must be complete. Record remaining dates as assumptions when they have not been supported by evidence.
GAO’s Schedule Assessment Guide provides a reference for integrated scheduling and evaluating changes. Connect service milestones with the manufacturing time-to-market plan and the wider site readiness review.
Compare rates using the same operating profile
DOE’s utility rate evaluation guidance distinguishes energy, demand and fixed charges. Review the applicable tariff, eligibility, billing rules and operating profile rather than comparing a single quoted electricity price.
Hypothetical monthly example: assume 1,000,000 kWh of energy and 4,000 kW of billing demand in both cases. The invented rates below illustrate two cost components only.
| Illustrative component | Rate A | Rate B |
|---|---|---|
| Energy charge | 1,000,000 kWh × $0.08/kWh = $80,000 | 1,000,000 kWh × $0.07/kWh = $70,000 |
| Demand charge | 4,000 kW × $12/kW = $48,000 | 4,000 kW × $18/kW = $72,000 |
| Energy-plus-demand subtotal | $128,000 | $142,000 |
$128,000
Rate A subtotal
The higher energy rate is paired with the lower assumed demand charge.
$142,000
Rate B subtotal
Its energy charge is $10,000 lower, but its demand charge is $24,000 higher.
Under these assumptions, Rate B’s subtotal is $14,000 higher. These figures are not provider quotes or benchmarks. Actual bills may include fixed charges, time-of-use rules, demand look-back provisions, minimums, power-factor adjustments, delivery charges, taxes or other items.
Model the actual rules over the relevant operating scenarios, including ramp-up and growth. Add upgrade and connection costs to the wider manufacturing location cost comparison without double counting them.
Confirm responsibility and later-phase capacity
Funding and scope
Identify provider and customer work, upfront contributions, connection charges, operating responsibilities and cost assumptions awaiting confirmation.
Future service
Ask which later-phase capacity is evaluated or secured, which conditions apply and what additional work remains.
Expansion interfaces
Protect space and access for added equipment and services, and plan changes beside operating production.
A future production line, process change, additional shift or new charging load should trigger a review of the underlying assumptions. An earlier study may not cover a materially different operation.
Carry confirmed requirements and open questions into manufacturing infrastructure planning. Keep technical, commercial and delivery responsibilities connected through design and implementation.
Turn the evidence into clear decision conditions
1. Investigate
Identify the providers, operating requirements and questions that could materially change site viability.
2. Validate
Obtain the appropriate studies and specialist findings, and define feasible work with costs and dependencies.
3. Review the commitment
Present unresolved conditions, funded responses and remaining exposure to the authorized decision-makers and advisers.
4. Verify delivery
Track acceptance requirements and update the record when service, design, production or project conditions change.
Hand over the requirements brief, provider records, responsibility matrix, cost basis, schedule dependencies and open-action register. Each material issue needs an owner, next action and review date.
Keep essential gates separate from weighted preferences in the manufacturing location scorecard. Use the manufacturing location risk assessment to explain consequences and responses, and coordinate property findings with facility due diligence.
Utility due diligence FAQs
What is utility due diligence in manufacturing site selection?
It is the investigation of whether a site can receive the services the operation needs, including capacity, technical characteristics, infrastructure work, timing, costs, responsibilities and agreement conditions. The findings should support a defined location or project commitment.
What should manufacturers send to a utility provider?
Provide the candidate site, production process, equipment and load information, operating profile, service characteristics, initial and future demand, target milestones and relevant reliability needs. Identify estimates still awaiting design confirmation and keep the request updated.
Does an availability letter confirm that capacity is reserved?
Read the actual document and ask the provider what it confirms. Clarify scope, conditions, validity period, required agreements, payments and remaining approvals. Have the appropriate advisers review the commitments before relying on them for a material decision.
How is connected load different from peak demand?
Connected load describes installed equipment ratings. Peak demand depends on how loads operate together under relevant conditions. Qualified electrical specialists should develop the profile needed for provider studies and service design rather than relying on the equipment total alone.
Why should wastewater be reviewed separately from water supply?
The ability to supply water does not establish that the receiving system can accept the planned wastewater. Review flow, constituents, treatment suitability, pretreatment, discharge conditions and approvals with the receiving authority and qualified advisers.
How should manufacturing sites compare electricity costs?
Use the same consumption and demand assumptions, then apply the actual rate eligibility and billing rules. Include relevant energy, demand, fixed and other charges, together with one-time infrastructure costs in the broader location economics.
Do two feeds or carriers guarantee independent service?
No. Separate connections may still share upstream equipment, corridors or other dependencies. Review the actual architecture and recovery arrangements against the process requirements with the responsible technical specialists and providers.
When should utility due diligence be updated?
Refresh it when design, equipment, production, service dates, provider conditions or expansion requirements change. Keep the evidence, cost assumptions, delivery dependencies and owners active through the transition from investigation to verified operating service.
