IT implementation at TPDDL

Praveer Sinha, CEO & Managing Director, Tata Power Delhi Distribution Limited

Tata Power Delhi Distribution Limited´s (TPDDL) journey started from July 01, 2002, and has since then made significant changes in the lives of the citizens of north and north-west Delhi. Today, we have around 1.6 million satisfied customers and serving a population of over seven million citizens.

During the last 14 years, TPDDL has attained several benchmarks in the field of operational performance and service. Today, the company ensures 24x7 quality power supply to all of its consumers. It has been able to free its licensed area from load shedding, bring down the average of 15 per cent load shedding (around six to eight hours in 2002) by ensuring adequate availability of power, a strengthened network and intervention of superior distribution technologies.

AT&C losses in TPDDL´s area stands at 8.8 per cent, which is an unprecedented reduction of around 85 per cent from an opening loss level of 53 per cent in July 2002. In terms of commercial parameters, the ´New Connection Energisation´ time has been at record six days, which will help improve India´s rank in the ease of getting new connection index from 70 in 2016, to 26 in 2017.

As part of an overall plan to achieve the target levels of losses reduction and service reliability while accommodating new customers and a six per cent load increase per year, TPDDL has drawn a detailed roadmap comprising of combined and integrated Information Technology (IT) and Operational Technology (OT).

To plug the revenue leakages TPDDL started with metering all its consumers and DTs along with implementation of the Geographical Information System (GIS), Supervisory Control and Data Acquisition (SCADA) and Customer Relationship Management (CRM) system to build a strong monitoring mechanism.

The next critical stage was to integrate all standalone systems and build a robust system through implementation of integrated GIS, SAP CRM, Outage Management System (OMS), Distribution Automation (DA), Distribution Management System (DMS) and Automated Meter Reading (AMR). This has helped in achieving highest level of automation in all critical processes including network management, complaint management, revenue cycle management, asset management and customer service. TPDDL has thus covered all facets of technology management including financial management, human capital management, vendor management, risk management and even administrative management.

Long term goals
Sustainability is very important for TPDDL and it is thereby the first Indian utility to embark on the smart grid journey. Smart grid in electricity distribution brings in efficiency in the transmission system through implementation of different technologies.

Technologies like Advanced Metering Infrastructure (AMI) and demand response has given the opportunity to engage more with the consumers and share more information with the consumers, thus sensitising them in changing their behaviour with respect to energy consumption and uasage.

This combination of improvement in reliability, efficiency and ability to proactively anticipate breakdowns will help in reducing energy wastage, while changing consumers behaviour will result in more efficient and optimum use of electricity, which will support reduction in the peak and lead to a flatter demand curve. Thus, smart grid implementation has assumed immense importance from the perspective of conserving and preserving the environment. And, TPDDL is one of 13 global utilities who are part of the Global Intelligent Utility Network Forum, working together to develop and implement sustainable and smart technologies.

To take this journey ahead, TPDDL has set up a world class laboratory in its licensed area demonstrating smart grid technologies implemented by the utility. This lab provides a test lab to demonstrate smart grid technologies and the benefits of convergence of IT and OT for distribution utilities.

The focus is on ´hands-on´ demonstration of various technologies, products and solutions which help in providing an improved connectivity, efficiency and reliability that is both sustainable and scalable. The lab is broadly divided into two zones: technology and customer experience.

The key technologies demonstrated in lab are AMR, GIS, GSAS, SCADA/DMS, unmanned grid, OMS, AMI, solar integration, ADMS, FFA, power manager, home automation, anti-theft technologies and smart utility model. The lab provides a simulative environment for industry stakeholders, academia, international delegates, etc.

TPDDL shall continue to strive to attain several benchmarks and collaborate with various stakeholders to continue the excellence journey.
