Joetsu
Location: Niigata
Operator: Chubu Electric Power Co
Configuration: four 595-MW, 2+1 CCGT blocks with 7001FA+e gas turbines
Fuel: LNG
Operation: 2012-2014
HRSG supplier: Babcock-Hitachi
T/G supplier: Hitachi
EPC: Hitachi
Quick facts: Construction at Joetsu began in Mar 2007 for the first block and Apr 2008 for the second block. Test operations at the first GT at Joetsu began on 8 Dec 2011 and the first block went commercial on 1 Jul 2012. Fuel burn for the completed station is expected to reach 2mn tpy of LNG, eventually to be delivered from the adjacent Inpex LNG terminal. The first phase of the second block began trial operation on 4 Jul 2013.

Fuel: LNG
Operation: 2008
HRSG supplier: MHI
T/G supplier: MHI, Melco
EPC: MHI
Quick facts: Construction on the these units stared in Jul 2005 and the first set went online in Apr 2008. Construction was delayed twice due to reduced load growth. LHV thermal efficiency is 58%. NOX emmissions are about half the level reached by Shin Nagoya-7.

Yokkaichi Complex
Location: Mie
Operator: Tosoh Corp
Configuration: 1 X 42-MW LM6000 gas turbine CHP
Fuel: methane, hydrogen
Operation: 1999
T/G supplier: GE, Stewart & Stevenson
Quick facts: In Apr 1999, this GT was installed at a Tosoh Corp petrochemical plant. The machine burns methane and hydrogen, by-products of the naphtha cracking process at the Yokkaichi plant. Turbine exhaust is ducted to the adjacent naphtha-cracking furnace and used as combustion air, a modification that reduced the energy consumption per unit of ethylene produced by over 7%.
