RDSS consumer indexing checklist

Why indexing gets its own checklist

The Revamped Distribution Sector Scheme (RDSS) puts communicating meters on feeders and distribution transformers so DISCOMs can do energy accounting: energy in at the DT, energy billed to the consumers behind it, and the gap between them. That sum only works if each consumer is mapped to the right DT. Get 40 consumers wrong and one DT looks like a theft hotspot while its neighbour looks perfect.

Indexing is also the installation crews' starting list. A survey done carelessly costs you twice: once in bad loss figures, and again when crews can't find the premises.

Use this as a working checklist, and add whatever your DISCOM's own format asks for.

1. Before the survey starts

• Consumer list from billing. Export account number, name, address, meter number and tariff category. This is your master list; surveyors confirm it, they don't rebuild it.
• Network master. Substation, feeder and DT codes for the area, with DT names as staff know them locally. Surveyors should pick from this list, not type codes.
• Survey areas. Split the area by feeder or DT, or by a walkable cluster of lanes, and assign each to one surveyor or team.
• Form agreed with the DISCOM. Settle the fields and which are required before anyone goes out. Changing the form halfway means going back to premises.
• Phones ready. The survey app installed, the area's consumer list loaded, and a test submission done in airplane mode.
• A rule for unlisted premises. Decide what a surveyor does with a connection that isn't on the billing list. Record it, photograph it, flag it, and leave the decision to the office.

2. At each premises

• Consumer account number, matched to the billing list
• DT code, chosen from the master or scanned from the DT plate
• Feeder code (often implied by the DT, but confirm it if the network was reconfigured)
• Pole number, if your DISCOM tracks it
• Existing meter number and make, with a photo of the nameplate
• Meter location: outside wall, inside, meter room, and any access notes for the installation crew
• Photo of the premises
• GPS fix, with its accuracy recorded
• Notes on anything odd: no meter, meter bypassed, premises demolished, multiple connections

Make the DT code, meter photo and GPS required. Those are the three fields surveyors are most tempted to skip.

3. Quality checks during the survey

Review submissions daily, not at the end. The longer a mistake sits, the further the surveyor has walked from it.

• GPS accuracy. Reject fixes with poor accuracy, or ask for a retake. A fix 200 m off can put a consumer on the wrong DT on a map.
• DT code exists. Any code not in the network master is a typo or an undocumented DT. Either way, the office needs to know.
• Photos readable. A meter nameplate photo nobody can read is the same as no photo.
• Duplicates. The same account or meter number on two premises is a data error or a real problem; find out which.
• Consumers per DT. Watch for DTs with no consumers, or far more than the DT could carry. Both usually mean mis-mapping.

4. After the survey

• Reconcile the surveyed list with billing: consumers found, not found, and found but not on the list.
• Send corrected DT and feeder mappings back to the billing or GIS team in the format they need.
• Hand the indexed list to installation planning, with access notes.
• Keep the photos and GPS fixes. They settle later disputes about which premises is which.

Doing this in PIEBENCH

PIEBENCH ships a Consumer Indexing template that starts with a photo and a GPS fix, and you add the fields your DISCOM wants in the form builder. The consumer list imports as service points, surveyors work offline in the Scout Android app, and supervisors review each survey in an approval queue. As surveys are completed, each service point moves from imported to indexed. See the consumer indexing app page, or RDSS smart meter installation software for the wider scheme.
