Title: Power Stations in Estonia


1
Power Stations in Estonia
  • By Ann, Annika, Kerli, Jaana, Kaija, Merit, Diana

2
What is oil-shale?
  • One of the most important mineral products found
    in Estonia
  • Resembles brownish,
  • flaky stone
  • Thin oil-shale leaves
  • can be lit with a match
  • reason to be called
  • burning rock in Estonian

3
First power plants
  • At the end of the 19th century power engineering
    development began in the largest towns and
    industrial centres of Estonia- Tallinn, Pärnu,
    Kunda, Tartu and Narva
  • Power engineering in Narva connected with
    industries such as Kreenholm Manufactory, the
    Narva Flaw Mill and the Narva Cloth Factory
    (worked on water!)

Power stations in Estonia
  • Based on oil-shale
  • The Balti Power Plant
  • The Eesti Power Plant
  • The Iru Power Plant
  • Cover 95 of
  • energy needs

7
The Balti Power Plant
  • One of the worlds biggest power stations
  • that uses oil-shale
  • Built 1956-1965,
  • fullpower 600 MW,
  • uses 10-12 million
  • tons of oil-shale per year
  • Possible to use oil-shale ashes no need to
    process raw material less pollution

8
The Eesti Power Plant
  • the biggest power station in the world that uses
    the local oil-shale with low calorific value
  • Full power is
  • 1610 MW

9
The Iru Power Plant
  • Near Tallinn, built to heat Lasnamägi (Tallinns
    district) and Maardu
  • Since 1993 gas has been used (low repairing
    costs, higher profitableness)

10
Ash hills
  • The ash- as result of production activity is
    stored in the ash disposal area located not far
    from the power station
  • 100 million tons of ash sediments
  • Most ash can be used liming acid soils in
    agriculture but
  • MOST ASH FORMS ASH HILLS!

  • 950 kWh/month 8 students (18)
  • do not know 15 students
    (33)

13
A Survey among students (2)
  • How do you save energy at home?
  • 1. Saving bulbs (30)
  • 2. Daylight lamps (11)
  • 3. Lower (night) price for higher power machines
    at home (26)
  • 4. Automatic electric heating (5)
  • 5. Switching lights off when leaving a room (45)
