GE and EDF officially began operation of the first ever combined-cycle power plant equipped with GE’s HA turbine in Bouchain, France, launching a new era of power generation technology and digital integration. GE also announced that the company has been recognized by Guinness World Records for powering the world’s most efficient combined-cycle power plant based on an achieved efficiency rate of up to 62.22% at the Bouchain plant.

In addition to achieving unprecedented levels of efficiency, GE’s HA gas turbine delivers more flexibility than ever before, capable of reaching full power in less than 30 minutes. This helps pave the way for greater use of renewable energy by allowing partners to respond quickly to fluctuations in grid demand, integrate renewables onto the grid and adapt quickly to weather changes. These advances support the recent Paris COP21 agreement, where 195 countries pledged to reduce greenhouse gas emissions, placing more emphasis on cleaner electric power opportunities.

The Bouchain plant is also an important demonstration of GE’s Digital Power Plant capabilities, which have helped drive the record-breaking levels of efficiency by unlocking power that was previously inaccessible. Capabilities, including the digital control system, use real-time data to deliver better plant outcomes with stable and efficient operations, while providing valuable predictive insights for higher reliability and optimization.

With a generating capability of more than 605 MW, the Bouchain plant will generate the equivalent power needed to supply more than 680,000 homes. In addition, the HA compressor flows air at a rate that could pump up the Goodyear blimp in 10 seconds, and the tip of the last blade in the 9HA.01 moves at 1200 mph/1931 kph — 1.5 times the speed of sound.

Siemens hat seit dem Frühjahr 2015 Aufträge über insgesamt sechs SGT6-8000H-Gasturbinen aus Mexiko erhalten. Since the spring of 2015, Siemens has received orders for six model SGT6-8000H gas turbines from Mexico.

Siemens has received an order to supply two SGT6-8000H gas turbines and two SGen6-2000H generators for the Empalme II combined cycle power plant in Sonora, Mexico. The plant will have an installed electrical capacity of 791 megawatts (MW). The customer is a consortium consisting of the Spanish engineering and construction companies Duro Felguera and Elecnor and the Mexican subsidiary Elecnor Mexico. The operator of the plant will be the state-owned power provider Comisión Federal de Electricidad (CFE). Commercial operation is scheduled for April 2018. Additionally, Siemens will provide technical assistance during construction and commissioning of the plant. Since the spring of 2015, Siemens has received orders for six H-class gas turbines from Mexico.

“CFE is becoming a pioneer in the integration of environmentally-compatible and resource-saving power generation solutions in Latin America. With these steps, Mexico will become an energy hub in the region and a reference for other similar projects”, declared José Aparicio, Vice President of the Siemens Power and Gas Division for Latin America.

A total of six model SGT6-8000H gas turbines are to be installed in the Empalme I (770 MW), Empalme II (791 MW) and Valle de México II (615 MW) combined cycle power plants. Siemens is also supplying two SGT6-5000F gas turbines for the Tula plant located in Hidalgo, Mexico. These four power plants have a combined electrical capacity of 2,727 MW, enough to supply one million households in Mexico with electricity. Siemens has sold 76 H-class gas turbines worldwide to date. The SGT-8000H fleet, with 16 units currently in successful commercial operation, has already achieved more than 195,000 fired hours.

 

Abengoa, the international company that applies innovative technology solutions for sustainability in the energy and environment sectors, has been selected by Jamaica Public Service (JPS) to carry out the engineering and construction work for a 190 MW combined cycle plant that will be the largest of its kind in Jamaica. The contract for the plant, which will be powered by natural gas and cooled by sea water, is worth more than US$200 million.

Abengoa will be responsible for the design, engineering and construction work of a plant that will replace an existing fuel-oil facility and is expected to create between 300 and 500 jobs during the construction phase. It will be located in the fishing village of Old Harbour Bay, around 76 km west of Kingston, Jamaica.

JPS wants to decommission the existing fuel-oil plant and move to a natural gas facility to create a cleaner, efficient and more reliable source of power. The upgrade to this plant reflects the government’s energy policy of generating up to 20 % of Jamaica’s power from renewable sources. The island currently relies on multiple plants to supply power to the island and Old Harbour is one of its oldest and least efficient plants.

The plant will use a seawater cooling system that returns the warm water without adversely impacting the environment. Abengoa’s design will use the existing infrastructure as much as possible, requiring less power and improving the overall output of the plant.

This latest project will extend Abengoa’s experience in turnkey combined cycle projects to the Jamaican market. The company’s other major combined cycle projects include the 640 MW plant in Centro Morelos (Mexico) and the 440 MW combined cycle plant in Portland, Oregon (USA), currently under construction. More recently Abengoa was awarded two combined cycle plants in Mexico – Nuevo Pemex (680 MW) and Norte III (924 MW).
