Eesti
Location: Ida-Varu
Operator: AS Narva Elektrijaamad
Configuration: 7 X 200 MW, 1 X 210 MW
Operation: 1969-1973
Fuel: oil shale
Boiler supplier: Taganrog, Foster Wheeler
T/G supplier: LMZ, Electrosila
Quick facts: Eesti is 20km southwest of Narva and is the world’s largest oil shale-fired power plant. Site preparation began in Mar 1963 and the first unit was commissioned on 30 Jun 1969 with a new design boiler. From 1998–2001, the two boilers at Unit-8 were dismantled and in Oct 2001 work got underway on retrofitting a new CFB boiler from Foster Wheeler. Start-up began in Sep 2003.

Boiler supplier: Taganrog
T/G supplier: LMZ, TMZ, Sibtjazmaz
Quick facts: This plant is the largest thermal energy producer in Estonia, supplying heat to approximately 50% of Tallinn. Iru has two generating units with oversize boilers plus three hot-water boilers and an auxiliary steam boiler. Total capacity is 190 MWe, 661.5 MWth hot water, and 162 MWth steam, all generated using natural gas and heavy fuel oil.
