Engine & Turbine Technology
Distributed power maintains power plant efficiency
More plants are using distributed power technologies to ensure a reliable energy supply. Eugene McCarthy reports.
Más plantas están implementando las tecnologías de distribución de energía para garantizar un suministro de energía confiable, afirmacEugene McCarthy.
Immer mehr Kraftwerke verwenden Technologien zur dezentralen Energieerzeugung, um eine zuverlässige Versorgung zu gewährleisten. Eugene McCarthy berichtet.
N
ew engine and turbine technologies are focused on highly efficient distributed generation from environmentally friendly
sources such as biogas, and on modular solutions that can be transported to locations with high power density needs. Distributed power technologies can ensure a reliable energy supply and increase productivity. Nigerian National Petroleum Corporation’s (NNPC) state oil refinery at Port Harcourt, Nigeria is the country’s largest oil refinery. It has suffered chronic grid outages, which affects capacity for refining. Up to now, grid outages have reduced PHRC’s output to 30% of its total maximum capacity of 210,000 barrels per day. Te outages and other factors have forced Nigeria to import large volumes of refined petroleum products to meet its domestic needs. GE’s Distributed Power is supplying
Genesis Electricity’s project company GEL Utility with three 25MW, trailer- mounted, TM2500+ aero-derivative gas turbines to generate uninterrupted power at the refinery, which will help the plant return to full refining capacity. Genesis Electricity, an independent
power producer and one of the owners of GEL Utility, signed a 20-year power
purchase agreement with NNPC in November 2013 for the installation of GE’s TM2500+ units at the 49-year-old refinery. Te TM2500+ gas turbines will provide the baseload and backup power to support refinery operations. Te agreement also includes the modernisation of Nigeria’s other two refineries. GE’s TM2500+ gas turbine is capable
of providing ISO-rated 31MW of fast and reliable on-site generating capacity. Te system can be used to provide utilities with a ‘baseload bridge’ to support permanent power installations, backup power to support natural disaster relief efforts, or for plant shutdowns or equipment maintenance. Te system can use either natural gas or liquid-distillate. MHI group member PW Power
Systems (PWPS) has landed a contract with Generación Frías, a subsidiary company of Albanesi, to provide an FT4000 Swiftpac unit for its location in Santiago del Estero, Argentina. Tis will be the first such unit in Latin America. Te new FT4000 Swiftpac gas turbine generator package produces a high output while maintaining high efficiency. Te FT4000 engine, powered by a
Pratt & Whitney PW4000 derivative gas generator, offers a 60-120MW package of reliable peaking and base-load power in a compact footprint.
