EVs and the Energy Grid

I must admit that I get excited just at the thought of non-polluting, noiseless electric delivery vehicles and passenger cars plying the roads, especially in a city like Bangalore where traffic jams challenge all your senses almost equally. No carbon emissions in the city! How great would that be!

But before we get too excited about that prospect, we also need to take a step back and think about the source of the electricity itself – how is it produced in India today? What is the share of renewable energy in our electricity consumption today? How will energy reach the average consumer, especially in high-usage zones in the cities? How will electric mobility impact the electric grid itself going forward?

These are some of the questions we try to answer in this month’s edition of “All about EVs”. Read on.

India’s power sector today

India’s total Installed Capacity as of 30th June 2021 stands at 384 GwH. Of which, thermal energy accounts for 60.9% (234 GwH), renewable energy accounts for 37.3% (55GwH) and nuclear energy accounts for 1.8% (6.7 GwH)

Who owns India’s energy installed capacity today?

The charts below show the break-up of the various sources of thermal and renewable energy in India today

How will India’s energy demand and supply grow?

India’s total electricity demand is expected to grow at a rate of 6.2% CAGR during the 15-year period ending 2030, as stated by Brookings, to reach 2338 TwH. Of the total electricity generated from our Installed Capacity, Central Electricity Authority (CEA) estimates the share of renewable energy at 44% of the total generated by 2030, while that of thermal energy is expected to reduce to 52%.


The share of EV’s in India’s total energy demand

Electric vehicles (EVs) are emerging as the focus of development in global mobility and are expected to increase the demand for energy manifold. India-specific estimates from electric mobility suggest a potential energy demand of 37 to 41 TWh in 2030, at the lower end of the range of estimates.

Estimate 1:
As per TERI’s Analysing and Projecting Indian Electricity Demand to 2030 report, published in 2019, the total electricity demand driven by EVs is estimated at 41–234 TWh (i.e. 1.75% – 10% of India’s total electricity demand as per the Brookings estimate above), biased towards the lower side of this range, and is therefore not considered a game changer for overall electricity demand to 2030.

Estimate 2:
As per a 2018 Brookings India reportat 33% EV penetration rate by 2030, the total electricity demand for EVs is projected to be 37 TWh. This constitutes less than 2% of the total electricity demand across the country by 2030. Therefore, meeting the overall energy demand for EVs is not expected to be a challenge in India. 

The largest segments for demand are the Bus and Commercial Vehicle (CV) segments. These segments are expected to have a higher penetration of EVs compared to segments such as the passenger 4-wheelers. Also, these segments have a higher electro-intensity per km and higher utilization rates (km/year), compared to the passenger car segment. 

A possible way to bridge the demand gap: Microgrids!

With the growing demand for electricity, microgrids help bridge the gap between demand and supply. They will also ensure efficient use of the total installed capacity India will be able to generate. Refer to the below diagram to understand the relationship between power grid and EV users.

What are Microgrids?

Microgrids are small-scale electrical networks that operate independently or in tandem with the main grid. Microgrids use renewable sources like solar photovoltaic cells and wind turbines to generate energy for use within a specific building or development. This enables them to operate independently without adding to the demand of the main grid.

Why are microgrids such a good idea? Electricity generated locally incurs much less loss than electricity that has to be transmitted from a long distance. Generally, 8% to 15% of energy generated from distant and centralized sources is lost during the transmission and distribution process.

Urban microgrids offer the exciting opportunity to turn underutilized assets and various types of “waste” into electricity and reduce greenhouse gas emissions. Electricity generated and stored by buildings and electric cars can also be harnessed by microgrids. 

Microgrids are needed in India given the huge mismatch between energy demand and supply.  Although microgrids in India have so far been used only on a selective basis, they will need policy and financial support from the Government to become economically viable at scale.

Microgrids in India:

India’s cumulative installed rooftop solar capacity stood at 6.79 GW as of Dec. 31, 2020, with 1.35 GW added in the last calendar year, according to the latest figures from Bridge To India.

TP Renewable Microgrid (TPRM), a subsidiary of Tata Power,  reported the commissioning of its 100th microgrid in rural India in November 2020, coinciding with its first anniversary. The 30kW solar-plus-storage microgrid in a village in the north-Indian state of Uttar Pradesh brings the total installed capacity of TPRM’s solar microgrid projects to 3MW. 

  • TP Renewable Microgrid is focussed on the delivery of its off-grid AC microgrid solution in states such as Uttar Pradesh and Bihar, where power is either unavailable or the supply is unreliable. 
  • TP Renewable Microgrid was launched by Tata Power in partnership with the Rockefeller Foundation in November 2019 with the aim to install 10,000 microgrids over the next decade.

Microgrids across the world:

Germany: In Berlin, over 350 micro grids have now been incorporated into the electricity grid. By the end of 2020, around 400 micro grids were targeted to  be integrated in the Berlin grid.

USA: Some of the most advanced microgrids in the U.S. are at universities, among them Princeton University, the University of Texas at Austin and the University of California, San Diego.In Ontario, a microgrid at Algonquin College demonstrates how to achieve maximum return on investment. Algonquin’s microgrid can operate independently from the central grid. But it will only do so at times when a power outage occurs or when being off grid offers economic advantage.
