• Resembles brownish,
• flaky stone
• Thin oil-shale leaves
• can be lit with a match
• reason to be called

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!
