Canada-based Emera Energy picked GE (NYSE: GE) to upgrade a 265-MW natural gas-fired combined cycle power plant in Rhode Island for $80 million.
The upgrades to the Tiverton Power Station’s 7F.03 turbines are expected to increase capacity by 22 MW and save approximately $1 million in fuel costs. The turbine’s heat rate is expected to improve up to 3.4 percent at New England ISO conditions while output is expected to increase up to 10.4 percent.
GE will incorporate three GE Power FlexEfficiency upgrade offerings, including a new .04 compressor, a Dry Low NOx 2.6+ combustor and GE’s Advanced Gas Path technology. GE supplied the plant’s original generation equipment. The upgrades will be performed during an outage scheduled for April 2016, with commercial operation to begin the following month.
Tiverton began commercial operation in 2000. Emera Energy acquired the plant in 2013 along with the 520-MW Bridgeport Energy plant in Connecticut and the 265-MW Rumford Power Plant in Maine.
