Five Centres of Excellence approved for newly recognised Classical Languages

CUET UGSSC CGLUP Samiksha Adhikari / Sahayak Samiksha AdhikariUPPSC RO / ARO

The Department of Higher Education approved five Centres of Excellence for Classical Assamese, Bengali, Marathi, Pali and Prakrit. The centres will support research, preservation, digitisation and wider dissemination of linguistic and literary heritage.

Why it matters

This is a culture-and-education institutional update. Students should learn the language-institution pair rather than treating all Centres as being in one central university.

Background you need

The approved host institutions are Tezpur University for Assamese, Visva-Bharati for Bengali, Deccan College in Pune for Marathi, Central University of Odisha for Pali, and Central University of Gujarat for Prakrit.

Concept map

Language heritage through academic institutions

  1. 1A Classical Language is matched with a host institution.
  2. 2The centre supports research and scholarly work.
  3. 3Resources are documented, preserved and digitised.
  4. 4Knowledge is disseminated to strengthen the regional academic ecosystem.

Cabinet clears Green Energy Corridor Phase-III for State-level renewable-power transmission

CUET UGSSC CGLUP Samiksha Adhikari / Sahayak Samiksha AdhikariUPPSC RO / ARO

The Union Cabinet approved Green Energy Corridor Phase-III to strengthen Intra-State Transmission Systems for carrying up to 135 GW of renewable electricity. The scheme also provides for 50 GWh of battery energy storage to make the grid more flexible.

Why it matters

This links renewable-energy targets to the less-visible grid infrastructure required to use wind and solar power. Generation capacity alone cannot deliver electricity reliably without transmission and balancing support.

Background you need

The scheme is targeted for completion by FY 2032-33 with a total project outlay of ₹1,86,405 crore and central financial support of ₹54,082 crore. State Transmission Utilities are the overall implementing agencies. Greenfield transmission projects use tariff-based competitive bidding, while brownfield strengthening is on a cost-plus basis.

Concept map

Renewable power from plant to grid

  1. 1Wind and solar projects generate variable electricity.
  2. 2State transmission infrastructure carries power from generation areas.
  3. 3Battery storage can absorb or supply electricity when needed.
  4. 4A stronger grid improves reliable renewable-energy integration.

Prelims recall

  • • GEC-III strengthens Intra-State Transmission Systems, not interstate transmission alone.
  • • It is designed to enable evacuation of up to 135 GW of renewable energy.
  • • The scheme includes 50 GWh of Battery Energy Storage Systems.
  • • The target completion year is FY 2032-33.

Quick check

Why is battery storage included in GEC-III?

It helps address renewable-power intermittency, congestion and demand outside solar hours.

Who is the overall implementing agency for the transmission component?

The State Transmission Utilities.

Election Commission revises SIR schedule for Andhra Pradesh and Meghalaya

CUET UGSSC CGLUP Samiksha Adhikari / Sahayak Samiksha AdhikariUPPSC RO / ARO

The Election Commission of India extended the Special Intensive Revision schedule in Andhra Pradesh and Meghalaya. The revised final-publication dates are 16 October for Andhra Pradesh and 26 October for Meghalaya.

Why it matters

Electoral-roll revision is important for prelims because it shows the Election Commission's administrative role. A revision schedule is not an election notification or a result declaration.

Background you need

For Andhra Pradesh, the notice phase and disposal of claims and objections runs until 10 October 2026. The release gives Meghalaya's revised final-publication date as 26 October 2026.

Concept map

Electoral-roll revision timeline

  1. 1The Election Commission sets a revision schedule.
  2. 2Eligible persons may file claims or objections during the designated phase.
  3. 3Authorities dispose of those claims and objections.
  4. 4The revised roll is published on the notified date.

Prelims recall

  • • SIR refers to Special Intensive Revision in this Election Commission update.

CUET UGSSC CGLUP Samiksha Adhikari / Sahayak Samiksha AdhikariUPPSC RO / ARO

The Cabinet Committee on Economic Affairs approved higher minimum support prices for all six mandated Rabi crops for marketing season 2027-28. Safflower received the largest absolute increase, ₹675 per quintal, followed by rapeseed and mustard at ₹413.

Why it matters

MSP is a high-frequency exam concept in agricultural policy. It is an announced support price, not a guarantee that every farmer will sell every unit to a government agency.

Background you need

The announced MSPs are wheat ₹2,610, barley ₹2,286, gram ₹5,958, lentil ₹7,390, rapeseed and mustard ₹6,613, and safflower ₹7,215 per quintal. The release says these are aligned with the policy of setting MSP at at least 1.5 times the all-India weighted average cost of production.

Concept map

How an MSP decision is read

  1. 1Government estimates relevant production costs.
  2. 2CCEA approves crop-wise support prices for a marketing season.
  3. 3The announced MSP signals the policy support level.
  4. 4Procurement operations follow under applicable schemes and arrangements.

Prelims recall

  • • The decision covers six mandated Rabi crops for the 2027-28 marketing season.
  • • Wheat MSP was set at ₹2,610 per quintal.
  • • Safflower received the largest absolute increase: ₹675 per quintal.
  • • Rapeseed and mustard MSP was set at ₹6,613 per quintal.

Quick check

Which Rabi crop received the largest absolute MSP increase in this decision?

Safflower, by ₹675 per quintal.

Is MSP itself the same as universal government procurement?

No. MSP is a support-price announcement; procurement depends on the applicable arrangements.

CUET UGSSC CGLUP Samiksha Adhikari / Sahayak Samiksha AdhikariUPPSC RO / ARO

The Ministry of Power notified new Corporate Average Fuel Economy norms for passenger vehicles, effective from 1 April 2027 through 31 March 2032. The rules apply to new passenger vehicles made or imported for sale in India.

Why it matters

This is a regulatory response to transport energy use. CAFE is a manufacturer-level fleet-average efficiency framework; it is not a single mileage promise for each individual car.

Background you need

The fuel-consumption benchmark tightens from 3.996 litres per 100 km in 2027-28 to 3.3273 litres per 100 km in 2031-32. The framework recognises technologies and provides compliance flexibilities, including specified credits and pathways for cleaner vehicle technologies.

Concept map

From vehicle fleets to energy efficiency

  1. 1A manufacturer sells a mix of new passenger vehicles.
  2. 2The fleet is assessed against prescribed average-efficiency targets.
  3. 3Targets tighten over the five-year framework.
  4. 4Technology choices and compliance mechanisms support lower fuel use.

Prelims recall

  • • The new CAFE norms run from 1 April 2027 to 31 March 2032.
  • • They apply to new passenger vehicles manufactured or imported for sale in India.
  • • The benchmark declines from 3.996 to 3.3273 litres per 100 km across the period.
  • • CAFE means Corporate Average Fuel Economy.

Quick check

Does CAFE prescribe the same fuel consumption for every car?

No. It sets fleet-average obligations for manufacturers.

When do the new CAFE norms take effect?

1 April 2027.
