What is an AMISP? Smart metering contracts explained for field teams

The short version

Under the old model, a DISCOM bought meters and paid a contractor to fit them. Under RDSS it buys a service instead. One company, the AMISP, takes on the meters, the communication network, the head-end system and the upkeep, and the DISCOM pays it every month for as long as the contract runs.

If you work for an installation agency, the AMISP is usually your client. If you work at a DISCOM, the AMISP is the company whose progress you check. Either way, the contract explains a lot about why the field work is run the way it is.

TOTEX and DBFOOT, in plain words

Two terms come up in every AMISP tender.

TOTEX means the project is paid for as a mix of capital and operating expenses rather than one big purchase. As the Prayas Energy Group explains, the AMISP carries the cost up front and recovers it over the life of the contract.

DBFOOT stands for design, build, finance, own, operate and transfer. The model bid document issued by REC for appointing AMISPs uses this basis, as a Mayer Brown and AZB & Partners note describes. The AMISP designs the system, raises the money, owns and runs it during the contract, and hands it over at the end.

How long the contract runs

According to the same note, the model contract stays in force until the earlier of 10 years from signing, or the point where the meter months used up exceed the total meter months. Total meter months are the number of smart meters installed, integrated and operationalised, multiplied by 93 months from operational go-live.

That last phrase matters on the ground. A meter that is on the wall but not talking to the head-end system has not been "installed, integrated and operationalised". The contract is built around working meters, not fitted ones.

Who pays whom

The DISCOM pays the AMISP monthly. To protect the AMISP, the model contract asks the DISCOM to set up a direct debit facility before the contract is awarded. The note describes it as a bucket-filling approach: consumer recharges and bill payments collected from the eleventh working day of one month to the tenth working day of the next go straight to the AMISP's account until the undisputed amount due is covered. If the DISCOM pays late, it owes interest.

Setting this up has not always been quick. In a July 2026 reply in Parliament, the Ministry of Power listed delays in signing the contract and the direct debit facility agreement among the reasons smart metering started slowly.

Where installation agencies fit

The AMISP signs with the DISCOM, but it rarely employs every installer itself. It usually works through installation agencies, each covering a set of divisions or a number of meters. The agency hires the crews, the AMISP sets the standard, and the DISCOM checks the result.

That chain is where field data gets lost. An agency that tracks installs in a spreadsheet, an AMISP that needs them in its own system, and a DISCOM that wants its own report means the same job gets typed three times. Each retyping is a chance to get a serial number wrong.

What the contract means for field teams

• Only working meters count. Payment and contract term both lean on meters that are installed, integrated and operational. A wrong serial or a meter that never commissions is work you did that may not be counted.
• Evidence is the safety net. When the DISCOM disputes a number, photos, GPS positions and scanned serials are what settles it.
• Availability is measured every month. AMISP contracts carry service levels for how much of the system is available. Non-communicating meters pull that number down, so someone will be sent to fix them. See AMISP SLA metrics.
• The data has to flow upward. Agency to AMISP to DISCOM, ideally without anyone retyping it.

How PIEBENCH fits

PIEBENCH is built for this chain. Agencies run their crews in the Scout app, the AMISP sees every agency's progress in one place, and DISCOM reviewers can be given read access to the AMISP's projects. See PIEBENCH for AMISPs and PIEBENCH for DISCOMs.
