Would smart grids resolve Gurgaons acute power crisis?

Back in 2012, an unplanned power outage for over 12 hours compelled Gurgaons irate residents to block the Delhi Gurgaon expressway. The situation hasnt changed much since then while many residents complain that they are still dependent on Diesel Generator sets as incessant power cuts continue to trouble them in sweltering summers.  

In order to address the perennial issue, last month, Power minister Piyush Goel revealed a plan to ensure an uninterrupted power supply in Gurgaon. Following the Union Ministers orders, Power Grid Corporation of India Limited (PGCIL), Dakshin Haryana Bijli Vitran Nigam (DHBVN), have started working on the plan to provide 24*7 power supply in the city on the Public-Private Partnership (PPP) model.

When it comes to electricity, Gurgaon's biggest problem is that demand exceeds supply, says, Manish Tiwari, an official working on Gurgaons smart grid project.

As confirmed by the CMs office, Haryana has got surplus electricity output. But due to the lack of transformers, and obsolete power infrastructure in the Gurgaon, a major loss of power transmission is happening, he adds.

However, according to Tiwari, smart grid is the one stop solution for Gurgaons acute power crisis that would address several issues including poorly planned distribution network, low metering efficiency and regulation of power tariffs.

What is smart grid?

A digital grid that ensures smooth transmission without theft and losses,, aims for even distribution of power and integrates the other renewable sources like solar and wind energy.

How smart grids would help in gauging demand?

An estimated amount of Rs 150 crore would be spent on the smart metering system called Advanced Metering Infrastructure (AMI). With the help of this, the DHBVN and PGCIL would be able to develop a sustainable mechanism to generate power for the consumers.
 
The power consumption would be examined block by block and sector by sector. In one block, for example, there is one transformer for 20 houses. Tomorrow, if the number of houses in the area increases to 25, with the help of smart grid technology that sends information to the control room about the consumption, we track the load capacity of the transformer with the help of consumption data available. Consequently, we inform DHBVN to install another high capacity transformer in the area. explains Tiwari.

Further, smart grid would bring efficiency in the power supply and facilitate reduction in AT&C losses, reducing faults and improving power quality and create an infrastructure of renewable energy resources.

Work at Ground Zero

Haryana Power Secretary Rajan Gupta, Municipal Commissioner of Gurgaon Vikas Gupta, Deputy Commissioner T L Satyaprakash and Chaiman and Managaing Director of Power Grid R N Nayak have been assigned to prepare a proposal for implementing the smart grid project here.

A detailed project review for Gurgaons smart grid project has already been prepared and sent for the approval to the CMs office and Ministry of Power, says an official.

By the end of May, DHBVN workers would start working on installing transformers and power cables across Gurgaon. The smart grid project has been divided in two phases in Gurgaon. Sector 1 to 56 would be covered in first phase while rest of the areas would be covered n the second phase, he adds.

HERC plans to install solar rooftops on public buildings..

An amount of Rs 650 crore has been earmarked for the smart grid and renewable energy integration which include solar net metering system.

Haryana Electricity Regulatory Commission (HERC) passed a regulation in the November last year, also layout a plan for giving incentives for solar power generation to the residents. It helps residents to generate solar power on rooftops through photo voltaic cells.

HERC, in collaboration with other authorities, would also be installing solar rooftops on the public buildings.

Shopping malls, high rises or the building with four floors and above, police station, petrol pumps, metro stations hospitals, schools (private) and all government administration building are to be covered under the project. The solar net metering would be connected with the smart grid technology. However this is to be introduced in the later part of the project, elaborates an official at HERC.

How smart energy meters would help in regulating power tariffs?

A smart meter would be installed in every house sending data to the centralised control room. With the available data and information provided by such smart meters, the discoms will be in a position to set up the pricing systems for electricity. Thus electricity tariff would be prepared based on the electricity consumed in peak and normal hours. This would further help homeowners and suppliers to manage the power usage in a more cost-effective manner.

Control rooms would get timely alerts

The system monitor would give timely alerts by examining the functioning of the transformers, and sending updates to the control rooms about the power load or in case the coil is overheating.

Smart grid would also allow consumers to save power and money

The smart grid system would be charging customers at the rates depending upon the time of use. For consumers, the app based technology would also be offered where they would be receiving timely updates on mobile about the current usage. This way, a consumer could decide to switch off his/her TV, geyser or air conditioner to save power and money.
