Scaling Up

Utilities aim for widespread smart meter deployment

Metering is a crucial area for distribution utilities as it is the first step towards energy accounting and revenue generation. So far, system and consumer metering has progressed well in the country though some states continue to be laggards in terms of implementation.

Current metering status

At the all-India level, there are about 214,175 feeders at the 11 kV level, 33 per cent of which are in urban areas and 67 per cent are in rural areas. Notably, the progress of feeder metering in both urban and rural areas stands at 99 per cent each. However, feeder metering is below 50 per cent in a few north-eastern states, including Arunachal Pradesh, Meghalaya and Nagaland. Distribution transformer (DT) metering has not progressed at a good pace. Out of over 12 million DTs, 83 per cent are in rural areas and 17 per cent are in urban areas. Nearly 68 per cent of DTs in rural areas are unmetered, whereas in urban areas, 43 per cent are unmetered, which is a cause for concern. States like Punjab, Rajasthan and Odisha have low levels of DT metering with progress of less than 15 per cent. The government is laying greater emphasis on DT metering and monthly/bimonthly reviews are being carried out to ensure that targets are met.

On the consumer metering front, the progress varies across segments. It is estimated that there are nearly 300 million electricity consumers in the country, of which 80 per cent (242 million) are domestic consumers, 9 per cent (26.8 million) commercial, 1 per cent (3.4 million) industrial, 8 per cent (23.3 million) agricultural and 2 per cent others. In terms of metering progress, nearly 6 per cent of consumers are unmetered in the domestic segment, 7 per cent in the commercial segment, less than 1 per cent in the industrial, and 61 per cent in the agricultural segment. Uttar Pradesh and Jammu & Kashmir have recorded low levels of consumer metering at 57.11 per cent and 49.8 per cent respectively. In Jammu & Kashmir, significant metering works are being undertaken under various government initiatives including the Integrated Power Development Scheme (IPDS), the Deen Dayal Upadhyaya Gram Jyoti Yojana (DDUGJY) and the Prime Minister’s Development Programme.

  Government initiatives in metering

Some of the major government programmes are the IPDS, DDUGJY, the Smart Metering National Programme (SMNP) and the National Smart Grid Mission (NSGM).

IPDS: The IPDS, which is aimed at providing 24×7 power supply in the urban areas, aims to undertake DT/feeder/consumer metering in urban areas. The programme was launched in November 2014 with a total outlay of Rs 326.12 billion including budgetary support of Rs 253.54 billion from the central government. Metering works under the IPDS entail metering of DTs, feeders and consumers in urban areas, and replacement of faulty and electromechanical meters with electronic meters. So far, 95 per cent of total consumer meters (8.7 million) sanctioned under the IPDS have been installed. The progress rate of system meters is at 92 per cent (total sanctioned: 0.12 million), smart meters at 76 per cent (total sanctioned: 0.16 million) and prepaid meters at 73 per cent (total sanctioned: 0.12 million).

DDUGJY: Launched in December 2014, the DDUGJY is targeted at electrification and distribution strengthening in the rural sector along with metering of DTs, feeders and consumers in rural areas. The scheme has an estimated outlay of Rs 430.33 billion, including budgetary support of Rs 334.53 billion.

A total of 16.6 million consumer meters have been sanctioned under the scheme and 3 per cent are yet to be installed. In the case of 11 kV feeders, 244,000 meters have been sanctioned, of which 43 per cent are yet to be installed. In the case of DT meters, 306,000 have been sanctioned, of which 28 per cent are yet to be installed.

SMNP: Energy Efficiency Services Limited (EESL) is implementing the SMNP with a target to replace 250 million conventional meters with smart meters. The programme is being implemented by EESL through demand aggregation, bulk procurement and monetisation of savings. Recently, EESL and the National Investment and Infrastructure Fund have formed a joint venture, IntelliSmart Infrastructure Private Limited, to implement, finance and operate the smart meter roll-out programme for discoms. Of the nearly 12 million smart meters under implementation across the country, EESL is engaged in the installation of 80 per cent. So far, nearly 1.4 million smart meters have been installed by EESL.

NSGM: Various smart grid pilot projects are under way under the NSGM. Advanced metering infrastructure (AMI) is a key component of projects under the NSGM. Currently, five smart grid projects have been sanctioned under it.

Apart from these programmes, the central government has asked states to move towards smart prepaid metering in three years. The Union Budget 2020-21 also focused on smart metering by utilities. Recently, the long-standing standard bidding documents for totex projects for smart prepaid meters have been finalised, which is a major achievement. They are now available on the NSGM website. In addition, options for a common back-end infrastructure facility for AMI projects are being explored.

Impact of Covid-19

Industrial demand was severely hit during the first two months of the lockdown imposed to contain the spread of Covid-19 in March-April 2020. Now the demand is back at pre-Covid levels. Power supply was not impacted because generation and transmission utilities continued to function as essential services.

The government also infused considerable liquidity into discoms through loans from the PFC and REC under the Atmanirbhar Bharat Abhiyan. In terms of project implementation, the lockdown impacted the progress of various smart metering projects, but improvements have been observed since July and August. In Uttar Pradesh, areas with smart metering witnessed around 95 per cent billing efficiency as compared to 76 per cent in areas without smart meters.

Net, net, smart metering is the way forward for the Indian power sector and the Covid-19 pandemic has further highlighted its importance for distribution utilities. Utilities have increasingly realised that if there had been widespread smart metering in their network during the lockdown, they would not have faced any billing/collection issues and decline in revenues.
