In short. Reddy Generators supplies new diesel generators, rents sets from its own fleet, and provides service, AMC, overhauls and spares for all makes across every district of Telangana and Andhra Pradesh, working from its office in Tarnaka, Secunderabad and its workshop at Amberpet, Hyderabad. Outside the Hyderabad rapid-response area, work is planned rather than improvised: visits are scheduled in advance, rental sets travel with what the site needs, and timing for any visit is confirmed when you call. This page explains how that planning works and how the region you are in should change the generator you specify.
Who this page is for: Owners, plant engineers, facility managers and project teams with sites in Telangana or Andhra Pradesh outside Hyderabad, who want to know how Reddy Generators plans sales, rental, service, AMC and spares for their location, and what to specify for their region’s conditions.
Key facts
- Coverage: all of Telangana and Andhra Pradesh, every district within about 300 km of Hyderabad in neighbouring states, and project-based work anywhere in India (including service work in Odisha and Assam).
- Same company, same engineering for every place: new sets of all major makes, rental, service and AMC, overhauls, alternator rewinding, AVR and controller work, AMF panels and changeover arrangements, and used and refurbished sets.
- Outside the Hyderabad rapid-response area, no fixed response time is promised: visit dates are agreed on the call, and planned work is booked ahead.
- The single biggest variable outside Hyderabad is distance. It changes what the engineer carries, what you keep on site, and how a rental is mobilised.
- Region matters as much as distance: interior Telangana heat, coastal salt and cyclones, and Rayalaseema dust and heat each call for different specification choices.
Our Hyderabad and Secunderabad generators page lists every district we cover in both states and describes conditions in the city itself. This page is about the rest of the map: what changes once your site is a few hours’ drive from Amberpet.
What changes with distance
A breakdown 15 km from the workshop and one 450 km away are different jobs. Nearby, an engineer can diagnose first and return with parts. Far away, the first visit has to be the fixing visit, so diagnosis moves to the phone and the photograph, and the van is loaded on the basis of what you tell us. The table shows how we plan by distance.
| Distance band (approx. by road) | Typical places | Service and AMC | Rental | What you should keep on site |
|---|---|---|---|---|
| Hyderabad rapid-response area | Hyderabad, Secunderabad and the surrounding urban belt | Engineer can normally reach a site the same day or the next working day | Delivery planned around city traffic and site access | Basic records: set details, alarm history |
| Up to about 200 km | Warangal (about 150 km), Karimnagar (about 165 km), Nizamabad (about 175 km), Khammam (about 200 km), Kurnool (about 215 km) | Day-return visits possible; AMC visits grouped by highway corridor | Single-trip delivery; cables and first-fill planned in advance | Filters and belts for one service, a spare battery for critical sets |
| About 200–400 km | Vijayawada (about 275 km) and Guntur (about 275–300 km, depending on route), Anantapur (about 360 km) | Visits scheduled ahead and combined with nearby sites; likely parts carried on the first visit | Mobilisation planned as a project; local fuel supplier agreed before arrival | A consumables kit, fuel and water separator elements, and a trained operator who can read alarms |
| Beyond about 400 km | Kakinada (about 480 km), Tirupati (about 560 km), Visakhapatnam (about 620 km) | Visits planned as trips covering several tasks or sites; remote triage before travel is essential | Best suited to longer hires; transport cost is spread over the hire period | Full service kit for the set, critical spares agreed with us, and clear photographs of the nameplates on file with us |
| Other states | Project basis anywhere in India | Scope, schedule and manpower agreed per project | Agreed per project | As agreed in the project plan |
Distances are approximate road distances and vary with route.
How service visits and AMC routes are planned
Outstation AMC sites are grouped along the main highway corridors out of Hyderabad: north towards Nizamabad and Adilabad, north-east towards Warangal, east towards Vijayawada and the coast, and south towards Kurnool and Anantapur. Sites on the same corridor are grouped into one route so that a team covers several sets in one trip, with the order fixed by priority and by which sets need a loaded test or a longer job.
Our maintenance of DG sets, AVRs and fire-fighting engines at nearly 50 TS TRANSCO substations across three divisions since 2018 is planned outstation work of this kind. The TS TRANSCO substation maintenance project describes the work, and our control-panel modernisation for TSGENCO at Nizamsagar is another example of planned outstation work (Nizamsagar project).
What makes an outstation AMC work well
- One named person at each site who can open the room, run the set and send photographs.
- Set details on our file: engine and alternator nameplates, controller model, battery type, last service hours.
- Consumables held on site between visits, so a filter change is never waiting for a courier.
- A monthly run log sent to us: hours, load, oil and coolant top-ups, any alarm text.
- Breakdowns between visits reported with photographs and alarm text, so triage can start on the phone and the right parts travel.
Details of what an AMC covers are on our AMC page.
Rental mobilisation outside Hyderabad
An outstation hire is a small logistics project. Before the set leaves Amberpet we agree: the truck route and any entry restrictions at the site; who provides the crane or hydra for unloading if the set is not lowered by the delivery vehicle; the cable length from the set position to the changeover; earthing; who supplies fuel locally after the first fill; and who on site will run the set and keep the log. For a long hire, train a site operator on day one: daily checks happen on site, engineer visits are planned events.
Our rental record outside the city includes 62.5 kVA acoustic sets for a national life insurer, whose Hyderabad branches were later joined by Vijayawada and Khammam branches (project); a 100 kVA set hired by South Central Railway for Bellampalli station in 2010; a 200 kVA rental for BHEL at the Rayalaseema thermal project (project); and generator rental for an offshore pipeline contractor at Kakinada (project). Hire engineering in general is covered in our rental power section.
Regional conditions and what they mean for the generator
Interior Telangana regularly sees heatwaves with daytime temperatures in the mid-40s °C, and the hottest places have recorded about 47–48 °C. The Andhra coast trades some of that heat for humidity, salt-laden air and cyclone exposure, and the Krishna and Godavari deltas add flooding risk. Rayalaseema is hot, dry and dusty, with long stretches of low rainfall. Each of these changes what a generator needs.
| Region | Condition | What it does to a generator | Specification and site decision |
|---|---|---|---|
| Interior Telangana (Nizamabad, Karimnagar, Ramagundam belt, Adilabad, Khammam) | Peak summer heat in the mid-40s °C; dry, dusty pre-monsoon months | Reduced cooling margin; output derating above the rated ambient; radiators choke with dust and debris | Check the ambient rating and derating curve on the data sheet; leave free air around the canopy; clean radiators before summer; see our summer precautions |
| Coastal Andhra (Visakhapatnam, Kakinada, Machilipatnam coast) | Salt-laden, humid air; cyclone season | Corrosion of canopy, hinges, terminals and radiator fins; moisture in alternator windings; long grid outages after storms | Coated canopy and corrosion-resistant fasteners; space heaters or regular runs for alternators; tie-down and a raised plinth; fuel autonomy planned for multi-day outages |
| Krishna and Godavari deltas (Vijayawada, Guntur, Eluru, Rajahmundry belt) | High humidity; flooding in heavy-rain years | Water ingress at low plinths and cable trenches; water in fuel | Plinth above known flood levels; sealed cable entries; fuel/water separator checks after rain |
| Rayalaseema (Kurnool, Anantapur, Kadapa, Chittoor) | Heat, fine dust, wind | Air filter loading; dust on radiator and alternator; derating at peak ambient | Heavy-duty air filtration with a restriction indicator; shorter filter intervals; derate for peak ambient |
| Long rural feeders across both states | Voltage dips and interruptions more frequent than in city centres | More starts; more running hours; more fuel to manage | Battery and charger condition become critical; plan refuelling and fuel control |
Supply quality varies more by feeder than by distribution company, so your own outage log is the best guide to your generator’s duty.
Regional decision table: typical sites and set sizes
| Region | Typical sites | Typical set size | Duty | Watch point |
|---|---|---|---|---|
| Northern Telangana | Rice mills, cotton ginning, granite processing, cold storages | 62.5–320 kVA | Prime power during outages, often long runs in season | Motor starting of crushers and compressors |
| Coal and power belt (Ramagundam, Kothagudem) | Contractors’ site offices, workshops, colonies | 30–250 kVA | Rental and project power | Dust and heat; long continuous running |
| Coastal Andhra | Seafood processing, cold chain, ports and marine contractors, pharma and engineering units | 125–1,000 kVA, often multiple sets | Standby for refrigeration and process; multi-day running after storms | Corrosion; fuel autonomy |
| Delta districts | Hospitals, colleges, commercial buildings, chilli and produce cold storages | 82.5–500 kVA | Standby with daily running in some seasons | Flooding; fuel water |
| Rayalaseema | Cement and mineral units, solar and project sites, warehouses | 62.5–750 kVA | Standby and project power | Heat derating; air filtration |
Typical ranges for planning only; your load list decides the size.
Worked example: the same load in three regions
Illustrative case. A distributor builds three identical warehouses with cold rooms, at Nizamabad, Kakinada and Anantapur. Each has a measured critical load of 80 kW at a power factor of 0.8.
- Base size: 80 kW ÷ 0.8 = 100 kVA.
- Anantapur (heat): if the chosen set’s data sheet rates it to 40 °C and its derating curve gives about 8 % less output at the site’s peak ambient (an illustrative figure: use the real curve), the requirement becomes 100 ÷ 0.92 ≈ 109 kVA, so a 125 kVA set is the practical choice. On 125 kVA (100 kW), the load is 80 %.
- Kakinada (cyclone): plan for 72 hours without grid. At an illustrative 0.27 L/kWh, fuel use is 80 × 0.27 ≈ 21.6 L/h, so 72 hours needs about 1,560 litres. A 200-litre base tank lasts only about 9 hours, so roughly 1,360 litres more must be stored on site in compliant storage before the season, along with corrosion protection and a tie-down.
- Nizamabad (frequent feeder interruptions): if the set averages 3 hours a day, it uses about 65 litres a day, or about 1,940 litres a month. Here the priorities are battery and charger health, a scheduled refuelling arrangement, and fuel accounting.
Same load, three specifications: heat rating at Anantapur, fuel storage and corrosion protection at Kakinada, starting reliability and fuel control at Nizamabad.

Common mistakes
- Expecting a distant breakdown to be fixed on the first visit without sending nameplate photographs, alarm text and symptoms beforehand.
- Specifying a coastal or Rayalaseema set exactly like a Hyderabad set, ignoring corrosion, dust and peak-ambient derating.
- Planning a rental at a distant site without arranging local fuel supply, unloading equipment and a trained site operator.
- Keeping no consumables on site, so a routine filter change waits for parts to travel.
What to send us
Send the site address and nearest town, what you need (new set, rental, breakdown, AMC, overhaul or spares), clear photographs of the engine, alternator and controller nameplates if a set already exists, your load or load list, the outage pattern, truck access details, and the name of a site contact who can run the set and send photographs. With that we can plan the right visit or quotation on the first call. Use the Outstation enquiry, or WhatsApp the details and photographs.
Questions customers outside Hyderabad ask
Do you provide generator service outside Hyderabad?
Yes. We service, overhaul and maintain generators of all makes across Telangana and Andhra Pradesh and in districts within about 300 km of Hyderabad in neighbouring states. Visit timing is confirmed when you call, and planned visits are scheduled in advance.
Can I rent a generator for a site in Andhra Pradesh?
Yes. Rental sets are mobilised from Hyderabad to sites in both states. We agree transport, unloading, cabling, earthing, local refuelling and a site operator before the set is dispatched. Longer hires make most sense for distant sites.
Do you take AMC contracts for generators in other districts?
Yes. Outstation AMC sites are grouped by highway corridor and visited on a planned calendar. Keeping consumables on site and sending us a monthly run log makes the arrangement work well.
Do you have branches in Vijayawada or Visakhapatnam?
We work from our office in Tarnaka, Secunderabad and our workshop at Amberpet, Hyderabad. Sites elsewhere are supported through planned visits and mobilisation from Hyderabad.
How quickly can an engineer reach a site in Warangal or Vijayawada?
We do not quote a fixed response time outside the Hyderabad rapid-response area. Timing depends on distance and the schedule, and is confirmed when you call. Sending photographs and alarm text first helps us bring the right parts on the first visit.
Can you supply a new generator to a site outside Telangana?
Yes. We supply new CPCB IV+ diesel generators of all major makes through supply tie-ups and can deliver and install anywhere in Telangana and Andhra Pradesh, and on a project basis elsewhere in India.
Does a generator for a coastal site need anything different?
Usually yes: corrosion-resistant canopy finishes and fasteners, care of alternator insulation against moisture, a raised plinth, tie-down, and enough stored fuel for multi-day outages after cyclones.
