Indian DISCOMs need to leapfrog with proven technologies rather than further experimenting as the country has invested several years on examining and verifying the deliverables by various technologies, observes Anil Daulani, Chief Executive Officer and Managing Director – India, CyanConnode. He also provides critical details about how advanced metering intelligence drives a smarter grid.

Why India needs smart grids?
With the vision of making India a 5 trillion-dollar economy and a global economic powerhouse by 2024-25, it is imperative that India’s power sector must grow rapidly in next 5 years. Many management reform programmes are being undertaken like smart prepaid meters through a new SBD, inclusion of distribution sub-licensee, and franchisee and many more to synchronise with technological interventions like smart grids to fast track this required growth journey. India needs to bring huge focus to improve its power distribution sector, which has been incurring billions of dollars of yearly losses for past several years.

The key technology foundation blocks for the power distribution infrastructure shall be selection and adoption of utility wide two-way communication infrastructure and platforms which converge IT system with Operational Technologies (OT) and maximise benefits by amalgamating automation and system efficiency.

Technological intervention like Advance Metering Infrastructure (AMI) which is an integral part of smart grid technologies coupled with structural/policy reforms, will allows for faster achievement of reduction in AT&C losses targets, improved cash flow by reducing the ACS-ARR gap, improvement in QoS and reliability of distribution grid.

Smart grid technologies have countless applications and advantages for multiple stakeholders like the utility, consumers, government, and policy makers. It will help to accelerate the curve for transitioning to low carbon footprint, open new opportunities for tech companies and help reduce electricity waste and energy costs.

Though India has made significant investment in implementation of smart grid infrastructure, it continues to make huge AT&C losses. What may be the reason?
As per the CEA estimates the existing generation capacity, along with the power projects to be commissioned, will be adequate to meet the energy demand growth.

Also, in the transmission sector the current pace of implementation of projects of interconnection of regional grid into national grid will further increase the inter transmission capacity. Deployment of smart grid technologies in generation and transmission sector has helped to achieve good outcomes.

Though the results are less visible in distribution sector because of various intertwined structural, financial, and technical issues, many utilities are redressing these issues at different levels. On the technology front, very promising results are achieved where utilities have adopted AMI on a mass level covering entire feeders and cities. The AT&C losses in these utilities have come down and have shown good operational efficiency gain but still a lot of ground needs to be covered. There is a clear need to deploy right communication technology, which can provide 24×7, always ‘on’ connectivity on IPV6 tunnel between each smart meter and HES (Head End System). Some of Indian consumers keep evolving new techniques to steal energy, which makes DISCOMs to incur heavy commercial losses despite installation of smart meters. There is need to create smart metering monitoring teams fully supported by near real time data acquisition by smart meters and right coordination with vigilance and field teams to work as “one effective team” in DISCOMs for bringing huge operational improvements.

There is need to capture data at source and utilisation of same time frequency by consumer smart meters and distribution transformer (DT) meters, to have near real time DT wise energy balance. Capturing low interval data like 15 minutes IP (Instantaneous Parameters) of consumer smart meters involving neutral current measurement and make MDM systems to have effective analytics capability to strengthen DISCOM teams with effective inputs to reduce commercial leakages. Without IP data collection, smart meters do not realise the actual benefits of such huge investments. It also helps consumers to monitor their near real time energy consumption (rather than seeing one day old data), which we can well achieve with right communication technologies.

The ambitious target of converting the existing 25 crore meters to smart meter is still at nascent stage. So Indian DISCOMs need to leapfrog with proven technologies rather than further experimenting as the country has invested several years on examining and verifying the deliverables by various technologies.

What needs to be done to get the best out of smart grid infrastructure?
Effective implementation of right technologies, replication of proven success model and providing the much-needed reforms (structural and financial) are the key to get the maximum benefit out of the technology driven change.

How advanced metering intelligence drives a smarter grid?
Adoption of advanced metering technologies shall enhance the performance of entire distribution network while reducing the losses. There is a need to mandatorily introduce smart meters in all customer segments. This will help DISCOMs manage load better while also reducing metering/billing losses, effective revenue protection measures. Smart prepayment meters will ease the cash flow challenges to a great extent.

Smart meters allow the introduction of a differentiated time-of-day tariff structure and facilitate the deployment of distributed rooftop solar (net meter) and introduction of various demand response programs. The access of the consumption data will give consumers insight to manage his usages, option to choose the tariff/programme to get benefited economically as well ecologically.

The growing deployment of AMI boons opportunities for improving quality of service, monitor voltage sag and swell, consumer load monitoring/meter data. DISCOMs are already achieving substantial value by using remote meter data to improve operations, design new services, catch hold of theft and defaulters, and improve customer relationships.

Brief us about your any success story on smart metering in India.
CyanConnode founded in 2002 is a leader in narrowband RF mesh network for IoT communication. Our standard based Omnimesh platform allows multiple routes to market and caters to multi-application network of smart grid. In last 9 years of operations in India, we undertook projects in various distribution utilities along with reputed meter manufactures and SI partners. Some of the projects which are completed and under support phase includes-UGVCL Ahmedabad, MPWZ Indore, CESC Mysore, Tata Power Mumbai, and APSPDCL- Tirupati. We are currently deploying over 1 million smart meters through our new projects.

Notably all the projects undertaken have yielded the desired results to maximise the system reliability, system efficiency, reducing energy and revenue losses.

There are numerous benefits achieved for customers (consumer energy usages behaviours using 15-min interval data), hourly analysis, consumption pattern on a mobile display, making consumers to regulate their behaviours to cut-down electricity bills, reducing the number of blackouts/brownouts and fast resolution to electricity failure) and advantages for utility are innumerable.

Our proven technology, passionate service delivery, handholding with stakeholders and treading extra mile across the project cycle has established us as differentiated AMI communication partner in market. Our open approach towards integration with multiple makes of meters or other end-devices, unique provisioning methodology to ease the field deployment of meters, added with well-documented ICT deployment and upstream system integration guidelines has fast paced the smart meter project deliveries.

In most of the projects, utilities benefited immediately with real time system parameters visibility. Theft cases easily detected, billing efficiency increases and with plenty of data points decision making becomes more scientific and economically fruitful.

In one of the Indian utilities, which deployed the CyanConnode AMI system for 1.20 lakhs consumers, utility has been able to achieve the average billing efficiency of 99.53 percent captured over a period of 20 months. In this case, utility has been able to recover its capex in 24 months’ time and moving ahead with larger deployments in 5 new cities. Many Indian and international utilities have witnessed this project and gained insights on its success to improve average revenue to the tune of Rs 550 per meter per bill in just 24 months’ time. This project has been well proven as one of the most successful Indian AMI deployment.
