were received for Trent 60 power generation packages to be
installed in the United States, Israel and Belgium, the last one
being for Trent gas turbines featuring the new power-enhanc-ing Inlet Spray Intercooling technology.
The U.S. contract, from Braintree Electric Light Department
in Massachusetts, U.S.A., was for two Trent 60 wet low emissions (WLE) units, capable of providing up to 116 MW of electrical power at the Thomas A. Watson generating station, a new
power plant to be constructed on the site of the retired Potter 1
station, located south of Boston, Massachusetts. They will provide cost-effective, environmentally friendly, efficient power to
meet the growing energy needs of Braintree Electric customers
and others on the ISO-New England grid, Rolls-Royce said.
The Belgian electricity utility, SPE, also selected two Trent
60 units for power generating packages to be constructed by
the Swiss power systems packager, Turbomach, S.A. SPE will
use its Trent 60 dry low emissions (DLE) engines at its Ham
power station, near Gent, to provide electrical power to the
national grid at times of peak demand.
At site conditions, each gas turbine has a power rating of 51
MW, but this will increase by over 11% when both engines
are upgraded at a later date with a new Rolls-Royce engineering development, Inlet Spray Intercooling (ISI). The boost in
performance will benefit SPE by allowing it to increase the
power produced from the units in hot weather with a nominal increase in first cost.
It was also an excellent year for aftermarket order intake,
according to Rolls-Royce. Aftermarket service activities for the
energy business now account for 46% of the total segment sales
and, with last year’s performance, the order book for long-term
service agreements has grown to more than US$270 million.
Rolls-Royce also claimed that it continues to enhance customer value through aftermarket product upgrades for
increased power, better efficiency and reliability, lower emissions and greater ease of maintenance. One such initiative is
the Avon 200, a new product with the potential to extend the
life of the worldwide Avon fleet.
It can deliver 6% more power, 3% better thermal efficiency
and reduced carbon dioxide emissions compared with current
in-service Avons, according to the company. Reduced fuel
burn, extended times between overhaul (up from 30 000 hours
