A DG AMC for bank branches differs from an ordinary maintenance contract in three ways: a written uptime commitment, records that survive an internal audit years later, and one accountable vendor across the whole branch network. The generator engineering is standard. The discipline around it is not — and the discipline is what banks are actually buying.
TL;DR
- The published bank configurations: 15–62.5 kVA per branch, 125–250 kVA for regional and zonal offices, 500–1500 kVA with N+ redundancy at main premises
- What changes at a bank: security-controlled access, audit-grade documentation, and uptime commitments in writing
- Installation clears the same statutory gates as any site — stack height and noise — but inside bank-premises protocol
- “RBI-grade” here is a project reference, not a certification: six 1010 kVA sets and three 30 m stacks delivered across Reserve Bank of India premises
- A branch-network AMC in our published terms: multi-brand, six visits a year typical, B-checks every 250–300 running hours, 4–6 hour breakdown response, 95% uptime with stated conditions, and a named escalation matrix
Why a bank branch is a different customer
The electrical load of a branch is ordinary. The operating context is not.
When the mains fail, the UPS carries the core-banking terminals and servers only long enough to bridge to the generator — it is not sized to run the building. If the DG set does not start, the branch stops transacting. Banks treat that as an incident to be documented and explained, not an inconvenience to be waited out — which is why our banking industry page puts it bluntly: downtime is a compliance event, and uptime commitments must be in writing.
Three more things separate bank work from factory work:
- The premises are security-controlled. Vendor access, material movement and photography are all controlled. An engineer without the right approvals does not reach the genset room; a vendor who cannot work inside that protocol slows the bank down every visit.
- Every visit is evidence. Every service visit, load test and part change must survive an internal audit years later. The service report is not paperwork after the job — it is part of the job.
- The estate is the customer, not the branch. A bank runs its DG fleet across dozens of branches, accumulated over years from different vendors and brands. What the estate needs is one accountable vendor with per-site schedules and consolidated billing — the structure our AMC desk runs for bank branch networks and JLL-managed facilities.
What the published configurations look like
These are the configurations published on our banking and financial services page, from work across the sector:
| Facility | Typical rating | What drives it |
|---|---|---|
| Branch | 15–62.5 kVA | UPS bridging, lighting, servers |
| Regional / zonal office | 125–250 kVA | Full-building load with lifts and HVAC |
| Data-adjacent / main premises | 500–1500 kVA | N+ redundancy, turnkey with exhaust structures |
The branch row is deliberately modest — a branch needs a reliable machine with its changeover proven, not a big one. The main-premises row says N+ redundancy: more capacity than the load strictly requires, so one set can fail or be released for service without exposing the building — which makes synchronising and load-sharing panels part of the turnkey scope, not an accessory. Confirming your own site’s number is the sizing guide’s job.
The statutory work does not shrink for a bank
Institutional installation means clearing the same compliance gates as any other site — with less tolerance for getting them wrong, because the consent file goes into the same audit trail as everything else.
Stack height. Up to 800 kW engine rating, the CPCB guideline formula applies: total stack height = building height + 0.2√kVA, so branch-class and zonal-class sets need only a modest extension above the roof. Above 800 kW — which includes the 1010 and 1500 kVA machines banks put behind main premises — a separate 2002 notification takes over, and its floor is a 30-metre stack. The full paper trail, formula and worked examples are in the stack-height guide.
Noise. DG sets up to 1000 kVA manufactured or imported on or after 1 January 2005 must emit no more than 75 dB(A) at 1 metre, with a factory-fitted integral acoustic enclosure — and separately, the site must meet ambient noise limits at its boundary, which vary by zone. Bank branches sit in commercial and residential areas, where that second, boundary test is the one that bites during test runs. The rules, the two regimes and the zone limits are in the noise-norms guide.
Neither rule bends for a bank. What changes is the execution: erecting a stack or craning a canopy onto a live, security-controlled bank premises is a choreography problem as much as an engineering one.
What “RBI-grade” means — literally
When this site says RBI-grade, it means something specific and checkable: work delivered inside Reserve Bank of India premises, executed to that institution’s own security and documentation discipline. It is a project reference — not an RBI certification, not an endorsement, and not a claim that any regulation obliges other banks to build the same way.
The reference itself: six 1010 kVA DG sets supplied, installed and commissioned across RBI premises at Belapur, Kharghar and Nagpur, with three 30-metre structural exhaust stacks — aviation lamps and lightning arrestors included — erected on live premises. The scope ran as one accountable bill: supply, installation, exhaust systems, civil works and control wiring, with commissioning documentation to institutional audit standard. The 30-metre stacks are not showmanship; a 1010 kVA set sits above the 800 kW line, where 30 metres is the statutory floor. The full record is on the project page.
The second bank reference shows the brownfield version of the same discipline: two turnkey 1500 kVA installations for Central Bank of India. Koti, Hyderabad took a full 30-metre stack. Belapur took the harder problem — 30 metres of engineered pipeline integrating the new set into an existing exhaust structure, on a working bank premises. Details are on the Central Bank of India project page. The sector client list also includes HSBC and Bajaj Allianz.
That is the connection between the big installations and the branch AMC: a vendor who has cleared RBI’s gate procedures and audit files has already rehearsed the discipline an ordinary branch network needs.
What a DG AMC for bank branches actually contains
A branch-network AMC is the multi-site version of our published AMC terms. The commitments a bank can put in its own audit file:
| Term | Published commitment |
|---|---|
| Uptime | 95% availability of the DG set, with stated conditions — load within 95% of rating (80% average), power factor around 0.8, OEM-spec fuel |
| Preventive visits | Typically six a year, bi-monthly |
| B-check servicing | Every 250–300 running hours — or calendar time on low-run sets |
| Breakdown response | 4–6 hours, through zone-based service associates |
| Escalation | Named matrix in the contract pack — zone associate, then national service manager, then the director, 24×7 |
| Records | Digital service history per set in DG Fleet Manager, documented per visit |
| Structure | Comprehensive (covered spares in the fixed price) or non-comprehensive (spares billed as consumed) |
Four of these matter most for a branch network.
Multi-brand is non-negotiable. A branch estate accumulates whatever each era’s tender produced — Cummins, Kirloskar, Perkins, MTU, Mahindra Powerol, Ashok Leyland. One contract covers them all: the same multi-brand mandate behind our Registered Service Provider status with JLL India and Authorised Service Provider status with Vertiv Energy India.
Branch sets are standby sets, and standby sets age on the calendar. A branch DG logs few hours, so the 250–300 hour B-check trigger rarely arrives — calendar time takes over, because oil, coolant, hoses and batteries deteriorate whether or not the hour meter moves. The A/B/C/D check ladder explains what each visit contains.
The escalation matrix has names, because branches need one number. A branch manager at 7 pm with a dead genset does not want a call centre. The contract pack lists who to call and who it escalates to, ending at the director — with numbers.
The uptime figure comes with its conditions attached. 95% is a written commitment, conditional on the set running within its rating on OEM-spec fuel — stated in the contract so both sides can audit them. An unconditional 100% is a line nobody can honour.
The multi-site discipline is rehearsed daily outside banking too — the same desk holds the AMC for Hardcastle Restaurants (McDonald’s India) outlets across Maharashtra, where per-site schedules and consolidated terms are the whole game.
What bank sites have taught us
Our banking page says the quiet part plainly: bank work is won on references and lost on paperwork. The field lessons behind that line:
- Plan the documentation before the work. On controlled premises you cannot go back for the photo you forgot. Commissioning files are assembled as the work happens, inside the institution’s photography and access protocol — or they are never complete.
- Access is a schedule item. Gate passes, material-movement approvals and personnel clearances take real days. Programmes that sequence them hold; programmes that treat them as formalities drift.
- Brownfield is the harder exam. Specifying a new stack on an empty yard is easy. Routing 30 metres of pipeline into an existing exhaust structure over a working bank — Central Bank of India, Belapur — is where installation experience shows.
- Today’s service report is read years later. Bank auditors pull old files. Reports written as evidence — what was tested, found and changed — protect branch and vendor alike.
One vendor, every branch
If you run power for a branch estate — five branches or five hundred — the structure to ask for is one master AMC, per-site schedules, consolidated billing, multi-brand coverage and an escalation matrix with names. That is the standing offer on our banking and financial services page, backed by the AMC terms above. Send your branch list and DG inventory on WhatsApp and you will get a straight proposal — structured the way your audit team will want to read it.
