Crystal Convention Center in Trichy is not a small venue. It has three convention halls that can host a thousand guests at once, fifty-two air-conditioned rooms, a full kitchen operation, and a lobby with its own AC load. Every event that walks through the door uses a different combination of halls, rooms, and services. Before Smart Nova, the billing team sat down after every function, tried to estimate how much energy each hall had used, applied a flat rate, and hoped the numbers were fair. There was no meter-level data, no automatic calculation, no GST breakdown, and no way to prove to a client exactly what they had consumed. EnSmart deployed Smart Nova across the entire facility — connecting every energy meter, tracking every zone, calculating every bill automatically with unit rates, CGST, and SGST — and handed Crystal Convention Center something no convention venue in Trichy had before: complete energy accountability for every event, every room, and every hall.

That is exactly how most convention centres in India handle energy billing today — a fixed package rate that has nothing to do with actual consumption. At Crystal Convention Center, the situation was the same. A wedding in Opal Hall 1 that ran the AC for twelve hours was billed the same way as a corporate meeting that used it for three. The kitchen ran its full load for a 1000-person banquet and for a 50-person breakfast — the energy cost was absorbed into a flat package either way. The facility had no meter-level visibility, no zone-wise consumption data, and no automated billing engine. Every invoice was a judgment call. And when a client questioned the bill, there was no data to show them — only an estimate backed by experience, not evidence.
The result:
Inside the full case study, you'll see:
| Year | Milestone |
|---|---|
| Phase 1 | Energy meter integration: all seven meters connected to Smart Nova — Opal Hall SSB 1 & 2, Kitchen SSB 1 & 2, Lobby AC, Opal Hall 1 AC, Opal Hall 2 AC — live readings verified for each zone |
| Phase 2 | 52 room integration: all AC rooms connected to Smart Nova, room-wise consumption tracking enabled and verified |
| Phase 3 | Billing configuration: unit rates configured, CGST and SGST at 9% each set up, Energy Cost Report template built and tested with live meter data |
| Phase 4 | Testing and commissioning: full billing cycle tested end to end — meter reading, consumption calculation, GST application, report generation — verified accurate across all zones |
| Phase 5 | Handover and go-live: facility team trained on Smart Nova billing and energy monitoring, first live Energy Cost Report generated, Crystal Convention Center live on Smart Nova — September 2025 |

A client books a hall, uses the air conditioning, runs the kitchen, fills the rooms — and receives a bill based on a package that has little to do with what actually happened. That system works until it does not — until energy costs rise, until a client questions the numbers, until the facility realises it has been absorbing losses it cannot even measure. Crystal Convention Center in Trichy chose a different path. They chose to know exactly what every hall, every kitchen circuit, and every guest room was consuming — and to bill for it accurately, automatically, and transparently. Smart Nova made that possible. M/s. Josh Automation made that partnership happen. And EnSmart is proud to have delivered a first for Trichy — a convention facility that operates with the same energy intelligence as the best hotels, IT parks, and data centres in the country. Every watt is now measured. Every bill is now provable. Every event leaves a data trail. That is what modern hospitality infrastructure looks like — and Crystal Convention Center is leading it in Trichy.
