Deendayal Upadhyaya Gram Jyoti Yojana (DDLJ DDUGJY)

When? Cabinet cleared the scheme in 2014, November.
Not announced yet. Although most likely power ministry- because they implemented Rajiv Gandhi Gramin Vidhutikaran Yojana earlier.

Salient Features?

  1. Separate agriculture and rural-home electricity supply lines. (separate agriculture and non-agriculture feeders).
  2. Improve rural electricity infrastructure, setup electricity meters, use ICT enabled smart grids.
  3. 24 x 7 electricity to all households by 2019.
  4. And most importantly- to stop Rajiv Gandhi Grameen Vidhyutikaran Yojana. (because two swords can’t stay in one scabbard.)
  5. Cost over 40,000 crore rupees.
  6. State electricity distribution companies will be given contracts but they’ve to finish projects within 2 years.

LED Schemes under Modi-raj

Theory CFL vs LED vs Bulb lights?
Filament Bulb
  • Electric current heats up tungsten metal and they glow. They are covered with glass to prevent air contact- otherwise tungsten will be oxidized.
  • Inert Argon gas added to prevent Tungsten evaporation.
  • Halogen bulbs have some halogen gas (like Chlorine, Bromine) to prolong life because they deposit the evaporated tungsten back to the filament.
  • LED 88% more efficient & 50x more lifecycle than bulb
Tube light
  • Electrons pass through mercury gas at low pressure.
  • This gas emits UV light
  • Inner Fluorescent white phosphor coating of the tube, will turn this UV-light into visible light.
  • LED 50% more efficient & 8-10 times more lifecycle than CFL.
  • Light emitting diodes (LED) use Semi-Conductors to emit light, when DC current passed.
  • Blue-LED inventors won Nobel-2014. click me for more


#1: National Program for LED streetlights & home lights
Purpose Install LED bulbs as streetlights and homelights
Deadline March 2015 to March 2016.
Coverage 100 cities.
Benefit? 24 crore energy units will be saved.
Why in News? Modi launched in Jan. 2015

#2: DELP: Delhi-wallo LED lelo Yojana

  • Domestic Efficient Lighting Programme” (DELP).
  • By Delhi Government, Tata Power, BSES Yamnua etc.
  • They provide LED bulb at a cheap price using “on-bill financing model”.
  • As such one LED bulb costs ~350-600 rupees in open market.
  • But this group purchased bulbs in bulk- hence very cheap for them.
  • They’ll sell it to you at Rs.130 per bulb. (Rs.10 upfront, remaining 120 in 12 easy installments of Rs.10 each- in your lightbill.) One customer can get max. 2 LED bulbs.
  • To avail this scheme, you’ve to register at eeslindia.org/Delhi-Launch or by sending an SMS to a 7042299688.
  • With every bulb, you can save Rs.162 in electricity bill every year. Bulb can run for 3 years.
  • Why in News? Modi launched this scheme in January 2015.

Fodder from Modi’s LED speech

  • Power can be produced in large quantity by staff of few hundred people.
  • But to save that much amount of electricity, we need crores of people to change their lifestyle habits.
  • But, It is much more economical to conserve power, than to produce power.
  • Must involve celebrities, eminent citizens to create junta-awareness.
  • On new year- instead of giving gifts like diaries and calendars- better give LEDs are gifts!
  • Same way, Companies could distribute LED bulbs along with dividend payments to their shareholders.
  • This Delhi-wallo LED-lelo Yojana should be replicated in other towns with population of 1 lakh and above.

#2: Floating solar powerplant

Floating Solar plant


  1. W.Bengal: 10KW plant over water, near Rajarhat New Town. (inauguration in Jan 2015)
    • Raft fitted with Hollow drums to float on water. Solar cells installed over the raft.
    • Funding from Ministry of new and renewable energy.
  2. Gujarat: solar cells installed above Narmada Canal. Even UN Secretary General Bank Ki Moon liked this idea.

Benefits of floating solar plants?

  • Water conservation: because these plants cutoff sunlight from water, thus water evaporation reduced from canals and dam reservoirs.
  • During dry-season, hydro-electric output declines from dam. If floating solar panels installed over dam-reservoirs, it can prevent shortfall in electricity output. + no additional manpower required for “chowkidaari”.
  • Such solar plants have higher efficiency because relatively cooler temperature in water bodies= higher efficiency of solar cell. 100 sq.meters of floating-solarcells can generate 10MW.
  • Shortage of land, and given the stringent norms in erstwhile LARR-2013 act, it was difficult to acquire land anyways!


  • NGOs say chemicals from solar cells, will contaminate water.
  • Panels obstruct sunlight from water bodies, it may negatively affect the flora-fauna in long term.
