SGT-A45 mobile unit brings fast power to Afghanistan
We have received an order for our SGT-A45 mobile unit from Bayat Power, a company of the Bayat Group. A few months from now, a complete gas-fired power plant, centered around the SGT-A45 trailer-mounted unit, will begin to provide electricity for 200.000 homes in the Jowzjan Province in northern Afghanistan.
It's the first new gas-fired power plant project in the country since the 1970.
The world's most powerful mobile gas turbineA dependable supply of electricity is at the very base of good living standards and economic growth. Several areas of the world continue to require the fast deployment of power solutions to quickly restore and upgrade a damaged or inadequate infrastructure, supporting developing economies or emergency disaster relief. With site installation in less than two weeks and an outstanding output of up to 44 MW(e), the SGT-A45 mobile gas turbine unit offers a cost-effective, dependable solution to these needs. Based on proven aeroderivative gas turbine technology, the SGT-A45 achieves the highest power density and fuel efficiency of all mobile power plants on the market. It can operate at either 50 or 60 Hz and offers a highly flexible solution for a wide range of applications.
SGT-A45 mobile unit highlights
The SGT-A45 achieves significantly higher power output and fuel efficiency than any other mobile gas turbine unit.
This translates into direct savings in initial capital investment (US$/kW) and operating costs (US$/MWh).
With these features, the SGT-A45 mobile unit offers you the best economics for fast power solutions.
The SGT-A45 mobile unit utilizes trailer-mounted modules which can be rapidly deployed by air, land or sea and are pre-commissioned at the factory in order to reduce the installation on site to less than two weeks.
The unit can generate electricity for 50 or 60 Hz power grids without any hardware modification.
The SGT-A45 is built with proven parts and advanced technology which has continuously been improved through extensive operational experience. The gas turbine utilizes proven components from both the Rolls-Royce Trent 800 with 28 million hours in flight and SGT-A65 (Industrial Trent 60) with more than 1.5 million hours in industrial applications. Considerable track record in naval marine propulsion completes the experience pedigree of this gas turbine technology.
The performance advantage of the SGT-A45 mobile unit is amplified in hot climates: At 30 °C and in 50 Hz operation, the SGT-A45 still retains almost all of its ISO-rated output, without any auxiliary water injection. When water is used for low NOx emissions (25 vppm with gas fuel and 42 vppm with liquid fuel), the output rating curve is essentially flat, with virtually no loss in power output across an ambient temperature range that extends beyond 40 °C.
Thanks to its aeroderivative architecture and the fast-responding agility required in flight, the SGT-A45 can complete a start from cold to full load in less than 8 minutes. From its use in aerospace it also inherits the ability to perform a very high number of start/stop cycles without impacting the durability of its parts.
Evolutionary design with a proven pedigree
The SGT-A45 engine core builds on the proven pedigree of Siemens aeroderivative gas turbines, utilizing Rolls-Royce aero engine technology.
It is derived directly from the SGT-A65 (Industrial Trent 60) core engine by removing the low-pressure compression module. The result is a compact gas turbine ready to be trailer mounted as a mobile unit, and yet characterized by exceptional power density and fuel efficiency. You will benefit from proven components with millions of service hours accumulated in flight as well as in industrial and marine applications.
The unit can generate electricity at either 50 or 60 Hz without any modification, and without a gearbox to match turbine and electrical generator.
Plug-and-play unit installed in less than two weeks
Every aspect in the SGT-A45 mobile unit is conceived to speed up and simplify installation on site. All the essential gas turbine auxiliary systems are trailer mounted at the factory, which reduces the necessary balance of plant equipment to a bare minimum. In addition, each SGT-A45 mobile unit is precommissioned and fully tested at the factory, minimizing the scope of commissioning at site. The trailer-mounted unit is driven to its installation site, requiring minimal civil works preparation.
Thanks to these and several other features, the SGT-A45 mobile unit can start producing power to the grid in less than two weeks after arriving on site.
A complete fast power solution
The SGT-A45 mobile unit is designed to make commercial operation of the complete power plant as fast as possible. With most systems already commissioned at the factory and the balance of plant equipment scope much reduced, the cost and schedule risks in site installation are minimized.
High availability by design – supported by tailored service solutions
Our comprehensive portfolio of services provides low life cycle cost and optimum performance throughout the turbine’s life cycle: Long Term Programs (LTP), overhaul service, field service, spare parts, service exchange, remote diagnostic service, and modernization and upgrades.
Whether for scheduled service or short-term support, our specialists are there for you, onsite all over the world. We can offer several levels of service plans for the SGT-A45, adapting to your specific requirements to provide the optimal service solution and highest levels of reliability and availability.
The combustion system of the SGT-A45 is identical to that of the SGT-A65 WLE. Its standard design features dual-fuel capability and offers the flexibility to switch between gas and liquid fuel automatically in all operating conditions.
Predictable maintenance regime
The SGT-A45 gas turbine keeps the same maintenance regime when operating with gas or liquid fuel.
