Dehli install smart power solutions

When industry reports last came in, India was amongst the leading electricity producers in the world. However, it still faces the challenge of providing electricity to all, on a 24 x 7 basis. Currently, over 300 million Indian citizens still do not have access to electricity, indicating a deep mismatch between demand and supply, affecting sustainable availability of electricity round the clock — at the right cost.

Aggregate technical & commercial losses (AT&C) are one of the key causes of this disparity, running as high as 1.5 per cent of the country’s GDP. Power theft, forming one of the major constituents of this figure, presents a difficult challenge to the utilities, who are striving to find a long-term solution to curb the menace.

Meanwhile, to curb energy theft, Tata Power Delhi Distribution Ltd (Tata Power-DDL) has empanelled Smart Energy Management solutions which have been displayed in the Smart Grid Lab of Tata Power-DDL.

The solution makes the smart meters tamper proof, manages asset management at the sub-stations and monitors behaviour of distribution lines. To deploy these solutions, Tata Power-DDL has roped in Omron Corporation. 

For making the smart meters tamper proof, Tata Power-DDL deployed OMRON Tamper Detection sensor and AC Latching Relay. The deployment of this solution underlined the pressing need of finding a long-term solution to the perpetual challenge of power theft caused by tampering of electricity meters. OMRON’s solutions empower the utilities to not only detect and track all key types of tampering (in homes and commercial buildings), but also disconnect the power supply remotely, if tampering or non-payment is observed.

That apart, managing distribution lines is a daunting task for any distribution company. Here, Tata Power-DDL showcases the utility of OMRON Wireless Power Sensor for the distribution companies facing the issue of power theft at the distribution lines. The sensor detects hooking and other means of tampering and manages harmonics and load balancing on the distribution lines.

Smart solutions for asset management at the substations, in this case OMRON Photo Electric & Fence Sensors, demonstrate the ability to detect and indicate unauthorised access to sensitive areas to manage and monitor the safety and security of valuable assets.

Tata Power-DDL has been the frontrunner in implementing power distribution reforms in the capital city and is acknowledged for its consumer-friendly practices. Since privatisation, the Aggregate Technical & Commercial (AT&C) losses in Tata Power-DDL areas have shown a record decline. Today, AT&C losses stand at 8.88 per cent which is an unprecedented reduction of around 82 per cent from an opening loss level of 53 per cent in July 2002.

On the power supply front too, Tata Power-DDL areas have shown remarkable improvement. The company has implemented high-tech automated systems for its entire distribution network in Delhi. Systems such as SCADA, Geographical Information System (GIS), Outage Management System (OMS), DMS and OTS are the cornerstone of the company's distribution automation project. To fight the menace of power theft, modern technologies like High Voltage Distribution (HVDS) System and LT Arial Bunch Conductor have been adopted.

Tata Power-DDL has to its credit several firsts in Delhi: SCADA-controlled Grid Stations, Automatic Meter Reading, GSM-based Street Lighting system and SMS-based Fault Management System. Tata Power-DDL's Smart Grid initiative with Automated Demand Response (ADR) is another first. To ensure complete transparency, Tata Power-DDL has also provided online information on billing and payment to all its 1.51 million consumers.
