TL;DR
Three-phase power at a factory—or a landlord’s verbal assurance that capacity can be increased—does not prove that the site can support production on schedule. Before signing, have qualified professionals calculate the actual demand, verify existing capacity through documents, a site inspection and written feedback from the competent electricity authority or zone operator, and allocate the external works, internal modifications, costs, timeline and consequences of failure in the lease. An upgrade is commercially viable only when it is technically feasible, affordable, deliverable on time and backed by enforceable responsibilities.
When your business receives information about a potential factory, the central question is whether the planned production line can be energized, tested and commissioned within budget and on schedule. Adding equipment nameplate ratings provides only preliminary data. A landlord’s representation or a contractor’s estimate also covers only part of the decision and cannot independently support a long-term lease.
This guide provides a pre-lease verification process. It starts with an electrical demand package, builds a six-layer evidence chain, separates external supply works from on-site distribution modifications, and then connects cost, milestones, responsibilities and exit rights in one lease-closing table.
1. How Do You Turn an Equipment List into a Verifiable Power Requirement?
Site comparisons should be based on maximum demand under actual operating conditions, starting-load constraints and reserve capacity for the planning period. Connected load is the sum of all equipment ratings. Maximum demand also reflects which assets operate simultaneously, how they start and how their loads change.
Why Can’t Nameplate Ratings Simply Be Added Together?
Equipment on the same production line may not operate at full load simultaneously. Motors, compressors and similar assets may, however, create short-duration starting demand. Power factor, cyclical loads, standby equipment, shift patterns and expansion plans can also change the final requirement.
A qualified electrical consultant should determine the appropriate diversity or demand assumptions from the equipment data and production cycle rather than apply a generic factor. Those assumptions should be recorded. Without this work, a seemingly precise total may overstate the required investment while still overlooking starting and peak-load risks.
What Should the Demand Package Include?
Record the following for each item of equipment:
- name, quantity, rated power, voltage and phase;
- starting method, operating hours and whether it runs concurrently with other equipment;
- importance to continuous production and any standby arrangement;
- planned expansion equipment and its expected commissioning date;
- auxiliary loads such as HVAC, compressed air, lighting, office systems, charging and life-safety systems.
The package should produce at least three outputs: maximum demand for initial operations, starting or peak-load constraints, and reserve capacity for the planning period. Each output should identify the calculation version and assumptions so that it can be compared directly with the site information.
💡 Our recommendation: Freeze the equipment list and production-cycle baseline before comparing sites. If the demand baseline keeps changing, the capacity conclusion, quotation and programme will no longer share a reliable basis.
2. How Can a Six-Layer Evidence Chain Verify Existing Power Capacity?
A distribution room’s apparent size, an equipment nameplate or a utility bill reveals only part of the supply position. A reliable conclusion must cover documents, physical assets, capacity allocation, the external network, on-site modifications and final energization.
Layer 1: Unit and Site Documents
Ask the landlord or zone operator for records of the current sanctioned or allocated load, connection and meter details, single-line diagram, as-built documentation, recent electricity bills and previous modifications. A bill can show historical consumption, but it does not by itself prove that sufficient capacity remains available to the leased unit.
Layer 2: Physical Electrical Assets
A qualified consultant should inspect the incoming supply, meter, transformer or substation equipment, main and sub-main distribution boards, busbars, cables, protection systems, earthing and space for additional equipment. The consultant should also confirm that the drawings match the installation on site.
Layer 3: Capacity Actually Allocated to the Unit
Capacity for an entire plot or building is different from the capacity a tenant can use. Separate the total capacity, the amount already allocated, the load used by other units and the remaining capacity that could be assigned to the proposed unit. The landlord’s representation should be supported by records from the zone operator or competent electricity authority.
Layer 4: External Network Feasibility
The competent authority and application route differ by Emirate, free zone and industrial park. The project team should identify the responsible electricity authority, submit the site location, required load and preliminary scheme, and obtain written technical feedback, design approval, a no-objection document or an equivalent written outcome, subject to the latest official publication.
In Dubai, for example, DEWA’s Getting Electricity service is initiated by an enrolled consultant or contractor. The process may produce a Building NOC, design approval and an estimated invoice, subject to the latest official publication. A landlord’s assurance or a general contractor quotation cannot replace that official stage. (Source: Dubai Electricity and Water Authority website, September 2026)
Layer 5: Feasibility of On-Site Modifications
From the ownership or metering boundary to the equipment, the project may require new or replacement main and sub-main distribution boards, cables, protection devices and final circuits. The team should also confirm shutdown windows, civil space, cable routes, fire-safety interfaces, and any landlord or zone approvals, subject to the latest official publication.
Layer 6: Testing, Inspection and Energization Conditions
Design approval, procurement, construction, inspection, defect correction, metering or connection, energization and equipment commissioning form a sequence of dependencies. Construction completion is only one milestone. The production date is credible only when the final energization and integrated commissioning conditions are defined.
⚠️ Common misconception: A large transformer does not automatically mean that the leased unit can use its apparent spare capacity. Equipment rating, capacity available at the site and capacity allocated to the tenant are three separate figures.
3. Why Must a Power-Capacity Upgrade Be Split into Two Workstreams?
A capacity upgrade usually combines supply conditions outside the responsibility boundary with distribution modifications inside it. The applicant, approval body, contractor, pricing method and party controlling the timeline may differ between the two workstreams. Managing them separately makes their interfaces and risks visible.
External Supply Workstream
External works may include a new connection, an adjustment to an existing connection, or network modifications involving a meter, substation equipment or cables. DEWA’s Electricity Network Modification information states that an enrolled contractor or consultant submits the relevant application, subject to the latest official publication. Whether that service applies to a particular project must still be confirmed against the site conditions and the authority’s response. (Source: Dubai Electricity and Water Authority website, September 2026)
On-Site Modification Workstream
Beyond the responsibility boundary, the scope commonly includes distribution design, switchboard and cable selection, protection coordination, controls, equipment circuits, civil reinstatement, testing and commissioning. The design consultant, contractor, equipment supplier and landlord need to work from the same load version and interface parameters.
How Do the Two Workstreams Connect?
At least five interfaces must be fixed: design parameters, ownership and metering boundaries, shutdown requirements, construction sequence, and prerequisites for final energization. External capacity without completed internal equipment—or completed internal works without connection approval—will still delay production.
💡 Our recommendation: Put both workstreams into one programme and identify the prerequisite and controlling party for every milestone. The resulting critical path, rather than either contractor’s installation schedule in isolation, should inform the target production date.
4. How Should You Verify Upgrade Costs and the Real Timeline?
An unbundled lump sum does not reveal what has been omitted or who carries the risk of an overrun. A free application also does not mean that the connection, equipment or network works are free. DEWA’s network-modification information distinguishes a free application from services that may be chargeable where applicable, subject to the latest official publication. It cannot be used to conclude that the project has no cost. (Source: Dubai Electricity and Water Authority website, September 2026)
The budget should separate at least:
- load studies, electrical design and professional consultant fees;
- application, connection or external network charges;
- on-site equipment, materials and construction;
- civil works, openings, fire stopping, reinstatement and production-shutdown support;
- testing, inspection, corrective work and commissioning;
- temporary supply arrangements and a reasonable contingency.
The programme should also separate document preparation, technical-feasibility confirmation, design approval, quotation and payment, procurement of long-lead equipment, external works, internal works, inspection and correction, energization, and commissioning. Lead times for transformers, switchgear and cables should be recorded separately; installation duration is not the total project duration.
Each quotation should state its validity period, taxes, assumptions, exclusions and site conditions. Any item that affects production but remains described as “subject to site conditions” is still an open cost risk and requires further evidence or budget protection.
5. How Does a Factory Power Lease-Closing Table Connect Engineering, Cost and Responsibility?
An engineering report establishes whether the work can be done. The lease determines who must deliver it and what happens if it cannot be delivered. One factory power lease-closing table can connect the two:
| Power requirement | Existing capability | Modification gap | Cost and timeline | Responsible party | Written evidence | Lease condition |
|---|---|---|---|---|---|---|
| Current maximum demand, peaks and reserve | Allocated capacity and on-site carrying capability | External upgrade or internal modification | Itemized quotations, critical milestones and float | Landlord, tenant, zone, electricity authority, consultant or contractor | Drawings, records, approvals, quotations and inspection results | Commencement, handover, rent start, extension or exit arrangement |
This is a gap-tracking tool, not a scoring model. If a technical fact lacks written evidence, a core cost has no defined boundary, or a critical milestone has no controlling party, the conclusion should not be “ready for production on schedule.” The item should move to further evidence collection or contractual protection.
The completed table should distinguish capacity that can be used immediately, gaps requiring only on-site work, and gaps requiring an external upgrade or network modification. It should also identify the cost bearer, payment triggers, baseline production date, critical path and alternative-site plan.
6. How Should the Findings Be Reflected in the Lease and Handover Plan?
A sentence stating that the tenant is responsible for arranging a capacity upgrade does not address capacity representations, cooperation duties or the consequences of delay. Key technical facts and cooperation obligations need to become enforceable transaction conditions.
A UAE-qualified lawyer should address the following in the context of the specific transaction:
- attach the existing sanctioned or allocated load, asset condition and supporting records;
- define responsibility for applications, design, payment, construction, site access, NOCs, inspection and energization;
- link lease commencement, rent commencement or formal handover to the critical technical conditions;
- provide for extensions, cost sharing, rent deferral, alternatives or exit rights if approval is delayed, the formal quotation exceeds budget, the target capacity cannot be provided or energization is postponed;
- determine ownership of new fixed assets, maintenance responsibilities and reinstatement obligations before construction begins.
The wording must be drafted for the location, zone rules and transaction structure. This framework organizes the engineering and commercial questions; it does not replace project-specific legal advice.
After production begins, maintain the approved drawings, connection conditions, test and inspection records, and subsequent change records. If equipment, load or layout changes, recheck the requirements of the competent authority and zone operator, subject to the latest official publication. Operating licences, facility approvals and annual compliance obligations should also be maintained in accordance with the latest applicable requirements.
7. How Can We Support a Pre-Lease Factory Power Decision?
Our recommendation is to move engineering verification into the lease-negotiation stage instead of treating it as a post-signing remedy.
For power-intensive factory projects, our team can assist your business in organizing the equipment load and production target, aligning the landlord, zone operator, qualified consultants and contractors around the same information, defining the external and internal scopes, and converting engineering gaps into budget, programme and lease-negotiation issues.
The purpose is to ensure that every party works from the same demand baseline, timeline and responsibility list. The competent electricity authority, engineering consultant and lawyer remain responsible for the professional conclusions within their respective scopes.
Frequently Asked Questions
Q: The Landlord Says the Site Has Enough Capacity. Is Professional Verification Still Necessary?
Yes. Confirm the site’s total capacity, the capacity allocated to the leased unit, the actual remaining capability and the internal distribution system’s carrying capacity separately. Cross-check the documents against the physical installation.
Q: Is the Sum of Equipment Nameplate Ratings the Capacity We Need to Apply For?
Not necessarily. Maximum demand also depends on simultaneous operation, starting methods, peaks, power factor, auxiliary systems and expansion plans. A qualified professional should calculate it.
Q: Are an External Capacity Upgrade and Internal Factory Modifications the Same Thing?
No. The electricity authority or zone operator manages connection and network conditions outside the responsibility boundary, while distribution inside the leased unit generally requires separate design and construction. The precise boundary depends on local requirements, site conditions and the contract, subject to the latest official publication.
Q: Can We Sign the Lease First and Apply for More Capacity Later?
The later application can be started, but the commercial risk depends on the lease protection. If capacity, budget and production milestones are not conditions precedent, rent may begin while the power remains unavailable.
Q: How Can We Obtain a More Reliable Cost and Timeline?
Complete the demand calculation and site inspection first. Then obtain written feedback from the competent electricity authority or zone operator, together with itemized quotations and programmes for the external and internal works. Before that, any budget remains assumption-based and should not be treated as a project commitment.
Seven Items to Confirm Before Signing
- Have qualified professionals calculated the maximum demand, starting constraints and reserve capacity?
- Is the existing capacity allocated to the leased unit supported by documents?
- Have the drawings and physical equipment been cross-checked?
- Has written feedback on external network feasibility been obtained?
- Have the on-site modifications been designed and quoted by scope?
- Does the programme cover approvals, procurement, construction, inspection and energization as one critical path?
- Are cost, responsibility, rent commencement, delay and exit arrangements documented in the lease or handover documents?
A factory’s power position is ready to support a lease decision only when technical feasibility, acceptable cost, a compatible timeline and enforceable responsibility are all established. Before negotiations close, place the equipment load schedule, site electrical records and target production date in one lease-closing table, then review it jointly with the landlord, zone operator, consultants and contractors.
