A statewide VSAT SCADA communication network for KPTCL's power grid
KPTCL's statewide transmission grid ran on an outdated communication backbone that delayed fault detection and outage management. Enview, with ABB Ltd., designed, supplied, installed, tested and commissioned an end-to-end VSAT network connecting 1,600+ remote sites for real-time SCADA monitoring and control - among India's largest utility SCADA networks.

Background
KPTCL operated an outdated communication infrastructure that limited real-time monitoring and control of its statewide power transmission network. Poor connectivity and unreliable data transmission delayed fault detection, outage management and operational decision-making, affecting overall service reliability.
Enview, in partnership with ABB Ltd., offered a complete end-to-end VSAT communication solution - network design, deployment, testing, commissioning and regulatory approvals. The ability to execute a large-scale, mission-critical communication network across Karnataka made Enview the preferred technology partner.
Solution
Enview designed, supplied, installed, tested and commissioned a statewide VSAT communication network connecting KPTCL's transmission sites to its State Load Despatch Center for real-time SCADA monitoring and control, engineered with full redundancy for mission-critical uptime.
- 2 × 9.0 m Earth Stations - a main hub plus a Disaster Recovery (DR) Center
- 1 + 1 hot-standby redundant architecture for uninterrupted operation
- 1,600+ VSAT remote sites across Karnataka
- 130+ enterprise routers and 900+ Layer-2 switches
- 100+ BSNL leased lines for terrestrial redundancy
- ABB RTUs and a Cisco VoIP network integrated for data and voice
- Site surveys, IP addressing design, FAT/SAT testing and government liaison for regulatory approvals and operating licenses
Implementation
The network has run as a mission-critical service across Karnataka for around 20 years. It was originally delivered under Envision Network Technologies; in 2019 the engagement transferred to Enview, which has since run statewide operations, maintenance and the redundant communication infrastructure - including the Disaster Recovery Center and 1 + 1 hot-standby systems - that keep KPTCL's power transmission network online.
