New Delhi, Feb 19: India will switch to the world's cleanest petrol and diesel from April 1 as it leapfrogs straight to Euro-VI emission compliant fuels from Euro-IV grades now - a feat achieved in just three years and not seen in any of the large economies around the globe.

India will join the select league of nations using petrol and diesel containing just 10 parts per million of sulphur as it looks to cut vehicular emissions that are said to be one of the reasons for the choking pollution in major cities.

Sanjiv Singh, Chairman of Indian Oil Corp (IOC) - the firm that controls roughly half of the country's fuel market, said almost all refineries began producing ultra-low sulphur BS-VI (equivalent to Euro-VI grade) petrol and diesel by the end of 2019 and oil companies have now undertaken the tedious task of replacing every drop of fuel in the country with the new one.

"We are absolutely on track for supplying BS-VI fuel from April 1. Almost all refineries have begun supplying BS-VI fuel and the same has reached storage depots across the country," he said.

From storage depots, the fuel has started travelling to petrol pumps and in the next few weeks all of them will only have BS-VI grade petrol and diesel, he said. "We are 100 per cent confident that fuel that will flow from nozzles at all the petrol pumps in the country on April 1 will be BS-VI emission compliant fuel."

India adopted Euro-III equivalent (or Bharat Stage-III) fuel with a sulphur content of 350 ppm in 2010 and then took seven years to move to BS-IV that had a sulphur content of 50 ppm. From BS-IV to BS-VI it took just three years.

"It was a conscious decision to leapfrog to BS-VI as first upgrading to BS-V and then shifting to BS-VI would have prolonged the journey to 4 to 6 years. Besides, oil refineries, as well as automobile manufacturers, would have had to make investments twice - first to producing BS-V grade fuel and engines and then BS-VI ones," he said.

State-owned oil refineries spent about Rs 35,000 crore to upgrade plants that could produce ultra-low sulphur fuel. This investment is on top of Rs 60,000 crore they spent on refinery upgrades in the previous switchovers.

BS-VI has a sulphur content of just 10 ppm and emission standards are as good as CNG.

Originally, Delhi and its adjoining towns were to have BS-VI fuel supplies by April 2019 and the rest of the country was to get same supplies from April 2020.

But oil marketing companies switched over to supply of BS-VI grade fuels in the national capital territory of Delhi on April 1, 2018.

The supply of BS-VI fuels was further extended to four contiguous districts of Rajasthan and eight of Uttar Pradesh in the National Capital Region (NCR) on April 1, 2019, together with the city of Agra.

BS-VI grade fuels were made available in 7 districts of Haryana from October 1, 2019.

Singh said the new fuel will result in a reduction in NOx in BS-VI compliant vehicles by 25 per cent in petrol cars and by 70 per cent in diesel cars.

The switchover, he said, is a tedious task as every drop of old, higher-sulphur content fuel has to be flushed out in depots, pipelines and tanks before being replaced by BS-VI.

"We are confident of disruption-free switchover to BS-VI supplies across the country," he said. "What we will be supplying is the best quality available anywhere in the world. You don't have any better fuel that is supplied in any part of the world. Perhaps our BS-VI fuel will be better than equivalent fuel in some parts of the US and Europe."

India adopted a fuel upgradation programme in the early 1990s. Low lead gasoline (petrol) was introduced in 1994 in Delhi, Mumbai, Kolkata and Chennai. On February 1, 2000, unleaded gasoline was mandated nationwide.

Similarly, BS-2000 (Euro-I equivalent, BS-1) vehicle emission norms were introduced for new vehicles from April 2000. BS-II (Euro-II equivalent) emission norms for new cars were introduced in Delhi from 2000 and extended to the other metro cities in 2001.

Benzene limits have been reduced progressively from 5 per cent in 2000 to 1 per cent nationwide. Lead content in gasoline was removed in phases and only unleaded gasoline is being produced and sold from February 1, 2000.

The octane number of gasoline signifies the improved performance of the engine. Loss in octane number due to phasing out of lead was made up by installing new facilities in the refinery and changes in refinery operation. RON (Research Octane Number) of gasoline for BS-2000 spec was increased to 88. This has over time been increased to 91.

Singh said sulphur reduction will reduce Particulate Matter (PM) emissions even in the in-use older generation diesel vehicles.

New Delhi, Jan 31: Substantial competition and low tariff rates by telecom operators since 2016 have led to a financial stress in the sector, the Economic Survey said on Friday.

The data price in the country came down by over 99 per cent during 2016-2019, making it among the lowest tariff in the world, according to the survey.

"Since 2016, the sector has witnessed substantial competition and price cutting by the telecom service providers (TSPs), creating financial stress in the sector. As a result, the sector is experiencing consolidation. While some operators have filed for bankruptcy, others have merged, in their quest to improve viability," the survey report said.

In April-June 2019, the price of data was Rs 7.7 per gigabyte (GB) as compared to Rs 200 per GB in June 2016, it added.

"The Average Revenue Per User (ARPU) for GSM based mobile services has also gone down substantially from Rs 126 in June 2016 to Rs 74.30 in June 2019," the survey said.

The tariff war started in the market with entry of new telecom operator Reliance Jio in September 2016.

"BSNL and MTNL are also affected by the tariff war that has impacted their cash flow resulting in mounting losses," the survey said.

The financial health of the public sector telecom firms plummeted to a level where they have been finding hard to pay employees salaries in time.

The government has drawn up a plan to revive these PSUs which is still in works.

The revival plan consists of several measures, including reduction of staff cost through voluntary retirement scheme, allotment of spectrum for 4G services, monetisation of land and building, tower and fibre assets of BSNL and MTNL, debt restructuring through sovereign guarantee bonds and ''in-principle'' approval for merger of BSNL and MTNL.

The survey said that the wireless telephony now constitutes 98.27 per cent of all subscriptions whereas share of landline telephones now stands at only 1.73 per cent where market share is dominated by private sector players.

"The overall tele-density in India stands at 90.45 per cent, the rural tele-density being 57.35 per cent and urban teledensity being 160.71 per cent at the end of September 2019. The private sector dominates with a share of 88.81 per cent (106.06 crore connections) at the end of September, 2019 while the share of public sector was 11.19 per cent (13.36 crore connections)," the survey said.

The lower price of data has also lead in surge of broadband connections and average consumption of the internet.

Total broadband connections increased by about ten times, from 6.1 crore in 2014 to 59.46 crore in June 2019, the survey said.

The number of internet subscribers (both broadband and narrowband put together) stood at 66.53 crore at the end of June 2019 as compared to 25.16 crore in 2014.

The number of mobile internet subscribers was 64.36 lakh at the end of June 2019 while the number of wireline internet subscribers was 2.17 crore.

"India is now the global leader in monthly data consumption, with average consumption per subscriber per month increasing 157 times from 62 MB in 2014 to 9.8 GB in June 2019. The cost of data has also reduced substantially, enabling affordable internet access for millions of citizens," the survey said.
