In short. Project, supplier and partnership enquiries to Reddy Generators should open with who you are, what you are proposing and what decision you need from us. A contractor needs a scoped DG package for a tender; a component supplier needs to show fit with the engines and alternators we service; a regional service or rental partner needs to show coverage and competence. State the scope, the location and the timeline, and attach only the documents that support the specific proposal.

Who uses this route
Three different kinds of organisation arrive through the same door, and the information each should bring is different. The first is the project organisation: an EPC contractor, electrical consultant, builder, data centre developer or plant owner in Telangana or Andhra Pradesh who needs generator capacity, panels, synchronisation or temporary power engineered into a larger job. The second is the supplier: a manufacturer or stockist of filters, batteries, AVRs, controllers, cables, enclosures, fuel tanks or switchgear who wants to be considered for our service, rental and installation work. The third is the partner: an independent service workshop, transporter, crane operator, rental fleet owner or electrical contractor in another district who could extend our reach or whose reach we could extend.
Each is welcome. Each also needs a different first message, and the sections below set out what belongs in it.
Project enquiries: define the power problem, not just the kVA
A project enquiry is strongest when it describes the operating requirement rather than a pre-decided equipment list. A tender line that reads one 500 kVA DG set with AMF panel tells us the budget assumption; it does not tell us whether the load includes a 75 kW fire pump that starts direct on line, whether a 200 kVA UPS sits behind the set, or whether the site is a basement with 30 metres of exhaust run. Those facts decide whether a 500 kVA set is right, oversized or inadequate, and they decide the panel, cable, ventilation and fuel scope around it.
For a project enquiry we would like to see the following, as far as it is known at the stage you are at.
- The facility type, location and whether the work is new build, replacement or expansion.
- The connected load and, if available, a load schedule marking essential and critical loads, large motors and UPS systems.
- The supply arrangement: DISCOM voltage, transformer size, existing changeover or synchronising scheme.
- Whether the requirement is standby, prime or continuous duty, and the expected hours per year.
- Site constraints: indoor or outdoor, roof or basement, noise limits, access for a crane or trailer, fuel storage limits.
- Programme dates and the division of scope between civil, electrical and generator contractors.
Where the requirement is still forming, our Power System Design Support and Application Engineering Enquiry routes exist to work through sizing, transient performance and architecture before equipment is fixed. For large or multi-set temporary schemes, see Multi-Megawatt Rental Power.
Supplier and partner enquiries
Suppliers: show fit with the machines we support
We service and rent diesel sets built on Cummins, Kirloskar, Perkins, Mahindra, CAT, FG Wilson, Greaves, Eicher and other engines, with alternators and controllers from the usual makers. A supplier enquiry is useful when it tells us which of those platforms your products cover, with part number cross-references, and how you handle the questions that matter in the field: traceability of the part, its origin, its warranty, lead time from Hyderabad stock versus factory, and minimum order quantities.
Our position on parts is set out in Parts Compatibility Verification and Used & Refurbished Parts Policy. In short, we fit parts whose identity and provenance we can state to the customer. A supplier who can document that is easy to work with; a supplier who offers a lower price without documentation is not, however attractive the price.
Partners: coverage, competence and clear boundaries
Generator work outside the twin cities often needs a local pair of hands: a workshop in Warangal that can do a first inspection, a crane operator in Vijayawada, a rental fleet in Visakhapatnam that can cover a shortfall. Partnership works when both sides are clear about what each is responsible for, what the customer is told, and how quality is checked. Tell us your base location, your coverage radius, your technicians’ experience by engine platform, your tooling (diagnostic software, load bank, lifting), your insurance position and references we may contact. We will tell you honestly whether there is overlap or a gap.
What to include, by enquiry type
| Item | Project | Supplier | Partner |
|---|---|---|---|
| Organisation, role and the person we should speak to | Yes | Yes | Yes |
| Location of the site or of your operation | Yes | Yes | Yes |
| Load schedule, single-line diagram or tender extract | Yes | No | No |
| Product range with engine and alternator cross-references | No | Yes | No |
| Technician count, platforms covered, tooling and fleet list | No | No | Yes |
| Programme or timeline | Yes | Lead times | Availability |
| Documents supporting any certification or test claim | If relevant | Yes | Yes |
| Confidentiality or tender restrictions that apply | Yes | If any | If any |
Evidence, claims and confidentiality
We ask every project, supplier and partner enquiry to state only what can be supported. A certificate should name the model and rating it covers; a test report should carry the date and the test conditions; a reference should be a site we may actually telephone. We apply the same discipline to ourselves, and our published position on it is in Document & Evidence Status. An introductory exchange does not make anyone an approved supplier or an appointed partner; that follows from scope agreed in writing.
Tender documents, customer load data and single-line diagrams are often confidential. Say so, and we will agree a channel and handling arrangement before you send them. Remove customer names where the enquiry does not need them. Do not send drawings marked restricted through a general messaging application without agreeing it first.
Common mistakes
- Sending a project enquiry as a one-line equipment list, which forces us to quote an assumption; the price then changes when the load and site are finally revealed.
- A supplier sending a general catalogue without saying which engine or alternator platforms the parts fit, which leaves us unable to place the offer against any real job.
- A prospective partner describing capability in general terms rather than by platform and tooling, which means the first joint job becomes the capability test.
- Claiming certification or project experience that cannot be documented, which ends the conversation once the documents are requested.
- Sending confidential tender material without agreeing how it will be handled, which puts both organisations in an awkward position.
What to send us
Send your organisation name, your role, the location concerned and a short statement of what you are proposing or asking for. Projects should attach the load schedule, single-line diagram or tender extract and the programme dates; suppliers should attach a product list with engine and alternator cross-references, lead times and any certificates; partners should attach a note of coverage area, technicians, platforms, tooling, fleet and references. Mention any confidentiality restriction up front. Use the enquiry form on this page or reach us through Contact Reddy Generators, and for employment or corporate matters use Careers & Corporate Enquiries.
Questions engineers ask
Can you work as a nominated generator subcontractor under an EPC or electrical contractor?
Yes, where the scope boundary is written clearly. Typically we take the set, its panel, fuel, exhaust and commissioning, and the main contractor takes civil works, cable trenches and the incoming supply. The interface points, especially earthing, cable terminations and control wiring to the ATS, must be listed in the scope split.
Do you buy from new parts suppliers, or only through established channels?
We consider new suppliers who can show part identity, origin and warranty in writing, and who can cross-reference to the engine and alternator part numbers we work with. Price alone does not open the door, because the part ends up in a customer’s machine under our name.
What does a service partner in another district need to have?
At minimum: technicians with experience on the common engine platforms, basic diagnostic tooling, the ability to reach sites in the coverage area within a reasonable time, and willingness to follow a shared checklist and reporting format so the customer sees one standard of work.
Will you sign a non-disclosure agreement before receiving tender documents?
Yes, where the project warrants it. Tell us in the first message that an NDA is required and we will handle that before any technical material is exchanged.
How early in a project should the generator supplier be involved?
Before the DG room and the main switchboard are frozen. Room size, ventilation openings, exhaust routing, fuel storage and the changeover scheme all depend on the set and its duty, and changing them after civil works are complete is expensive.
