Why in News?
- The Andhra Pradesh government has prepared a roadmap to transform the Andhra Pradesh State Road Transport Corporation (APSRTC) into a modern electric mobility-driven public transport system.
- The plan focuses on the gradual replacement of ageing diesel buses with electric buses and the deployment of cleaner fleets to reduce operational costs, improve environmental performance, and make public transport financially sustainable.
- The government has approved the procurement of 5,746 electric buses and 500 CNG buses over the next five years, along with additional buses under the Stree Shakti scheme.
- This marks a major shift in Andhra Pradesh’s public transport policy toward sustainable and green mobility.
Background of APSRTC Fleet Modernisation
- State Road Transport Corporations across India have traditionally depended on diesel buses due to lower upfront costs and the availability of fuelling infrastructure.
- However, diesel buses involve high fuel expenditure, frequent maintenance costs, and significant environmental pollution through emissions of particulate matter, nitrogen oxides, and carbon dioxide.
- Rising fuel prices and increasing urban pollution have made diesel-based transport economically and environmentally difficult to sustain.
- APSRTC has therefore initiated a structured transition toward electric mobility to improve long-term financial efficiency and reduce dependence on conventional fuels.
- The move also aligns with India’s broader national goal of clean mobility and reduced transport-sector emissions.
Present Status of APSRTC Bus Fleet
At present, APSRTC operates a total fleet of 10,951 buses.
Out of these:
- 8,199 are RTC-owned buses
• 2,752 are hired buses - Officials state that 2,630 buses, including 1,941 RTC-owned buses and 689 hired buses, will continue in operation because they will not complete either 15 years of service or their agreement period by 2030.
- This means these diesel buses must continue until the end of their approved lifespan.
- The remaining 8,321 buses are identified for gradual conversion into electric vehicles.
- This forms the core of the State’s electric mobility roadmap.
Government Roadmap for Electric Fleet Transition
The government has approved:
- Procurement of 5,746 electric buses
• Procurement of 500 CNG buses
• Proposal for 1,445 additional buses under the Stree Shakti scheme
• Procurement of 903 diesel buses for immediate operational needs - The diesel buses are being procured because large-scale deployment of EVs requires time for charging infrastructure, depot readiness, and route planning.
- Officials estimate that APSRTC requires financial assistance of ₹382 crore for the first year alone to meet the capital expenditure for diesel-to-electric bus conversion.
- This shows that the transition is planned as a phased and realistic reform rather than an immediate replacement.
Electric Buses in Public Transport
- Electric buses use battery-powered electric motors instead of internal combustion engines.
- Unlike diesel buses, they do not produce tailpipe emissions and therefore help reduce air pollution significantly.
- Most electric buses in India use Lithium-ion batteries, especially Lithium Iron Phosphate (LFP) chemistry because of better thermal stability and longer battery life.
- The typical operating range of an electric bus is around 150 to 300 kilometres per charge depending on battery capacity and route conditions.
- Electric buses are nearly 3 to 4 times more energy efficient than diesel buses because electric motors convert nearly 85–90% of input energy into motion.
- They also reduce operating costs by nearly 30–40% per kilometre over the long term.
- Charging systems generally include:
- Depot-based slow charging (6–8 hours)
Opportunity or fast charging (1–2 hours or less)
- Depot-based slow charging (6–8 hours)
- This makes them highly suitable for structured public transport operations.
Gross Cost Contract (GCC) Model
Most State Transport Undertakings in India deploy electric buses through the Gross Cost Contract (GCC) model.
Under this system:
- Private operators own and maintain the buses
• The government or transport corporation pays per kilometre of service - This model reduces the upfront capital burden on the government while ensuring professional maintenance and fleet management.
- It allows public transport corporations to expand electric fleets without bearing the full cost of vehicle ownership.
- The GCC model is widely used under national EV programmes and helps improve financial sustainability.
Diesel vs CNG vs Electric Buses
Aspect / Fact | Diesel Buses | CNG Buses | Electric Buses |
Main Fuel | High-speed diesel derived from petroleum | Compressed Natural Gas mainly consisting of Methane (CH₄) | Electricity stored in batteries |
Pollution Level | Highest pollution among all three | Lower pollution than diesel | Zero tailpipe emission |
Major Emissions | PM2.5, PM10, NOx, SOx, CO₂ | Lower PM and NOx, but CO₂ emissions and methane leakage concern | No direct PM, NOx, or CO₂ emission during operation |
Greenhouse Gas Concern | Major contributor to global warming | Methane leakage is serious because methane is more potent than CO₂ in the short term | Depends on electricity source; cleaner if powered by renewables |
Initial Cost | Lowest procurement cost | Moderate procurement cost | Highest procurement cost |
Long-Term Cost | Highest fuel and maintenance cost | Lower than diesel | Lowest operating and maintenance cost over time |
Noise Pollution | High engine noise | Moderate noise | Very low and much quieter |
Infrastructure Requirement | Existing fuel stations already available | Requires CNG stations and gas supply network | Requires charging stations and battery support system |
Environmental Status | Least sustainable option | Considered a transition or bridge fuel | Long-term sustainable transport solution |
Special Concern | High urban air pollution and fuel import burden | Methane leakage reduces climate benefits | Battery disposal and recycling challenge (lithium, cobalt, nickel) |
Government Policy Focus | Gradually being reduced | Used as an intermediate cleaner option | Strongly promoted under FAME India and PM e-Bus Sewa |
Strategic Benefit | High dependence on imported crude oil | Cleaner than diesel but still fossil-fuel based | Improves energy security and supports Net Zero 2070 target |

The shift from diesel dependence toward electric mobility reflects both economic necessity and environmental responsibility.
With phased implementation, policy support, and infrastructure readiness, Andhra Pradesh can build a modern, cost-efficient, and sustainable transport system.
Electric buses are not merely a technology change—they represent the future of public mobility and urban governance.
CARE MCQ
Q. With reference to electric buses in public transport, consider the following statements:
- Electric buses generally have higher energy efficiency than diesel buses.
- Under the Gross Cost Contract model, the State Transport Corporation owns and maintains the buses directly.
- FAME India Scheme supports electrification of public transport systems.
Which of the statements given above are correct?
A) 1 and 3 only
B) 2 and 3 only
C) 1 and 2 only
D) 1, 2 and 3
Ans: (a)
Explanation
Statement 1 is correct because electric motors convert nearly 85–90% of input energy into motion, making them far more efficient than diesel engines.
Statement 2 is incorrect because under the Gross Cost Contract model, private operators own and maintain the buses while the government pays per kilometre of service.
Statement 3 is correct because FAME India Scheme Phase II specifically supports electric public transport including electric buses.
Therefore, the correct answer is A.
Q. Consider the following statements regarding urban air pollution in India:
- Vehicular emissions are among the major contributors to particulate pollution in large metropolitan cities.
- Secondary pollutants such as ground-level ozone can form due to chemical reactions involving nitrogen oxides and volatile organic compounds in the presence of sunlight.
- PM2.5 particles are larger and less harmful than PM10 particles because they settle faster in the atmosphere.
Which of the statements given above are correct?
(a) 1 and 2 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2 and 3
Ans: (a)
Explanation:
Statement 1 is correct: In major Indian cities, vehicular emissions are one of the leading contributors to urban air pollution, especially PM2.5, nitrogen oxides (NOx), carbon monoxide, and hydrocarbons. Rapid urbanization, traffic congestion, and the growing number of private vehicles significantly worsen air quality. Diesel vehicles are particularly important sources of fine particulate matter.
Statement 2 is correct: Ground-level ozone is a secondary pollutant, meaning it is not emitted directly but forms in the atmosphere through chemical reactions. When nitrogen oxides (NOx) and volatile organic compounds (VOCs) react in the presence of sunlight, ozone is produced near the surface. This is harmful to human health and crops, unlike stratospheric ozone which is beneficial.
Statement 3 is incorrect: This statement is incorrect because PM2.5 particles are smaller and more dangerous than PM10, not larger. Their very small size allows them to penetrate deep into the lungs and even enter the bloodstream, causing serious cardiovascular and respiratory diseases. PM10 is comparatively larger and less penetrating. Therefore, PM2.5 is more harmful, not less.
Q. Consider the following statements regarding Electric Vehicle (EV) policy in India:
- The FAME scheme was launched to promote faster adoption and manufacturing of electric and hybrid vehicles in India.
- Lithium-ion batteries used in EVs depend significantly on critical minerals such as lithium, cobalt, and nickel.
- Under India’s EV policy, registration tax and GST on all EVs are completely removed by constitutional mandate.
Which of the statements given above are correct?
(a) 1 and 2 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2 and 3
Ans: (a)
Explanation:
Statement 1 is correct: The FAME Scheme (Faster Adoption and Manufacturing of Electric Vehicles) was launched by the Government of India to encourage the use of electric and hybrid vehicles. It provides demand incentives, supports charging infrastructure, and promotes domestic manufacturing as part of India’s clean mobility transition. FAME-II further expanded this support, especially for public and shared transport.
Statement 2 is correct: Most EV batteries are based on lithium-ion technology, which depends heavily on critical minerals such as lithium, cobalt, nickel, and graphite. These minerals are strategically important because supply concentration in a few countries creates economic and geopolitical risks for energy transition goals.
Statement 3 is incorrect: There is no constitutional provision mandating complete removal of registration tax or GST on all EVs. While the government has reduced GST on EVs to 5% and some states provide registration tax exemptions or subsidies, these are policy measures, not constitutional obligations. Therefore, the statement is incorrect.
