Why electricity needs to be monitored?

by Team Digireach

We are entering an age of data and information. Nowadays, its is easy and very much possible to track any kind of data. Electricity is our top-most source of energy. Tracking and monitoring of our consumption of our electricity can lead to extensive savings and improvement in our usage.

Advantages for Electric Companies

  • Constant tracking of energy parameters leads to increase in efficiency.
  • Automatic monitoring of electricity usage. This eliminates manual monthly meter readings.
  • Prevents failure of the system by predicting avenues of failure so that pre-emptive steps can be taken to address the same.
  • Reduce power outages (blackouts). Real-time data from energy meters gives the operators knowledge of the status of the power infrastructure and it’s usage
  • Dynamic pricing. Demand and supply of power will define the cost.
  • Avoids the capital expense of building new power plants
  • We will be ushering in a new age of market dynamics in electricity demand. This arrangement/ data can be further optimized based on requirements of AI (Artificial Intelligence) in the future.

Advantages for Users of Electricity

After the electric company has fully installed its advanced metering infrastructure, smart meters offer the following benefits to electricity customers:

  • Reduces the number of blackouts and system-wide electricity failures
  • Trend can be gauged from the graphs of electrical data. This can give a detailed feedback to the power companies. Necessary tweaks can be incorporated in the generation, transmission or distribution to optimize power consumption.
  • Constant tracking of power consumption can enable the consumers to make necessary changes in their habit of electricity intensive machinery utilization.
  • Dynamic pricing according to the day of the year and the time of day can lead to better utilization of existing resources. This can also lead to lower electricity bills for consumers.

As mentioned above, it’s a win-win situation. The earlier we usher in IoT and monitoring of data in the electricity sector, the greater advantage for the authorities and consumer it would be.

Smart meters and an IoT-enabled electricity infrastructure can provide quick, accurate measurements of electricity use while eliminating the need for estimated monthly bills or home visits from meter readers. The graphs and data collected across a period of time can help the authorities to plan and prioritize better.

This can lead to a reliable and strong electricity infrastructure for the future (Read: IPDS and RT DAS). Welcome Electricity 4.0.

Smart and pre-paid metering

by Team Digireach

How do we make the existing state utilities more efficient and bring down their losses? Smart prepaid electricity meters are one of the answers.

This step is likely to bring revolution in power sector by way of reduction in AT&C losses, better health of DISCOMs, incentivising energy conservation, ease of bill payments and doing away with the paper bills.

Smart meters are a part of the overall advanced metering infrastructure solutions (AMI) aimed at better demand response designed to reduce energy consumption during peak hours.

India plans to change all electricity meters to prepaid smart meters by 2022. This step taken by the government is to address the issue of energy efficiency and optimization. Electricity is the need of the hour. Electric power generation is a prime component in the development of a nation. It is the base to move any developmental activity in the right direction. Hence, it is being addressed on an urgent basis with help of schemes like IPDS (Integrated Power Development Scheme), RT DAS (Real-time Data Acquisition System). Energy metering system etc.

  • The government believes that the plan will increase distribution substation capacity by 38% by 2022

India has a beleaguered power sector. Proper monitoring and tracking of energy usage via smart meters would go a long way in addressing the problems of the existing energy infrastructure. The strategy is part of the government’s electricity distribution plan prepared by the Central Electricity Authority (CEA), India’s apex power sector planning body, and comes at a time when the new government is trying to step up its efforts to supply 24×7 power to all.

Creating a smart meter architecture minimises human intervention in metering, billing and collection process and helps in reducing theft by identifying loss pockets. It requires a two-way communication network, control centre equipment and software applications that enable near real-time gathering and transfer of energy usage information.

Smart metering would empower consumers with tools to help them conserve energy and plan their electricity usage in an efficient and optimum manner.

The plan of introducing smart meters is part of government’s plan to fix the power sector in the country. Stopping the unwanted pilferage and making consumers accountable for the usage and wastage will usher India to a new dawn of electricity.

Smart meters, electricity usage tracking, reducing wastage and cutting down on the transmission and distribution losses are the need of the hour.

What IPDS brings?

by Team Digireach

It is a flagship programmes aimed at increasing energy access among the poor. The IPDS is aimed at enhancing the power infrastructure in urban areas

Agenda of IPDS are as follows:

  • Reduction in AT&C losses
  • Establishment of IT enabled energy accounting/ auditing system
  • Metered consumption
  • Improvement in collection efficiency

Energy losses occur in the process of supplying electricity to consumers due to technical and commercial reasons.  The technical losses are due to energy dissipated in the conductors , transformers and other equipments used for transmission, transformation, sub-transmission and distribution of power.  These technical losses are inherent in a system and can be reduced to a certain level.

Pilferage by hooking, bypassing meters, defective meters, errors in meter reading and in estimating un-metered supply of energy are the main sources of the commercial losses owhen Commercial losses are added to Technical losses, it gives Transmission & Distribution (T&D) loss.

There is another component of commercial losses, which is attributable to non-recovery of the billed amount, which is reflected in collection efficiency. T&D losses together with loss in collection give us Aggregate Technical & Commercial (AT&C) losses.

Transmission & Distribution losses (T&D losses)

T& D Losses = { 1- (Total energy Billed/ Total energy Input in the system)} x 100

Aggregate technical and commercial losses (AT&C losses)

AT&C Losses = { 1- (Billing Efficiency x Collection Efficiency) } x 100 Where Billing efficiency= Total unit Billed/ Total unit Inputs Collection efficiency = Revenue collected / Amount Billed

Energy accounting is a system used in energy management systems to measure and analyze energy consumption to improve energy efficiency within an organization. Dashboards and sensor infrastructure can be arranged to collect and monitor data pertaining to energy parameters on a real-time basis. These systems can be used to track energy usage.

IPDS scheme, apart from ensuring 24×7 power supply in urban area, will also help in improvement in billing and collection efficiency which will ultimately result in reduction in Aggregate Technical and Commercial (AT&C or distribution) losses.

These are some of the advantages India can assume on successful implementation of IPDS technology.
