In short. In May 2010 a leading Indian aluminium producer awarded Reddy Generators a contract to hire, install and run a 125 kVA acoustic diesel generator at its corporate office in Bhubaneswar. The scope covered the whole installation, from earthing, armoured cabling, busbar and changeover switch to statutory clearances, an operator on a 12-hour shift, and all maintenance. The initial 12-month contract, with a performance review at six months, was then renewed for a further two years.

The requirement
A busy corporate office cannot stop for power cuts: computers, servers, lighting, lifts and air conditioning all depend on it. The client chose to hire rather than buy, and wanted one contractor to deliver a complete, legally cleared installation and keep it running, with nothing left for office staff to manage.
A complete installation, not just a generator
The contract treated the generator as one part of a working system. Around the set, the scope included its earth pit and earthing strip, 90 metres of armoured aluminium cable to the building, a 200 A busbar and a 200 A changeover switch, a compacted and levelled base with drainage, and a protection shed. Reddy Generators also took responsibility for obtaining clearance from the Electrical Inspector and the Pollution Control Board, so the installation was legal from day one.
Running it for three years
An operator ran the set on a 12-hour shift. Running hours and diesel were recorded in a log book signed by the client’s representative, and every monthly bill was reconciled against it. All periodic, scheduled and breakdown maintenance stayed with Reddy Generators. The contract built in a performance review after six months; at the end of the first year the client renewed it for two more years.
Outcome and limits
The hire ran for about three years in total, with the client choosing to renew after the first year. A renewal is the clearest evidence of satisfactory service that a rental contract can give. This record is based on the client’s letter of award and the renewal; operating logs are not published.
Questions engineers ask about this project
What site work does a long-term rental generator need?
More than the set itself: an earth pit, armoured cable to the building, a busbar and changeover switch, a level base, drainage and a protection shed. Here all of it was built as part of the hire.
Who obtains statutory clearance for a rental DG set?
On this contract the rental supplier took responsibility for obtaining clearance from the Electrical Inspector and the Pollution Control Board, with the fees paid by the owner. Agree who does this before mobilisation.
How is diesel use checked on a rented generator?
Through a log book of running hours and fuel received, signed by the owner’s representative and submitted with each monthly bill, so fuel is reconciled against actual use.
