A CCPP consists of 2 stages of power generator facilities. Primary power generation is done by gas turbine generator, and gas turbine exhaust is utilized as a heat source of a heat recovery steam generator (HRSG). Steam from that HRSG rotates a steam turbine generator as a secondary power. A CCPP has shorter startup time than a conventional steam turbine power plant of the same output and features excellent load response as well as high electrical efficiency. High electrical efficiency means minimal thermal energy discarded.

The newly developed CCPP is composed of two L30A gas turbines, two HRSGs, and one steam turbine, all produced by Kawasaki to make the CCPP a Kawasaki original power plant. Kawasaki brings together product technology and plant engineering capabilities cultivated over many years to achieve high efficiency in the combined cycle as a whole in addition to gas turbines alone. Total Electrical efficiency is 55.2% (reheat type) in the 100 MW class and 54.4% in the 90 MW class, both among the world’s highest levels of electrical efficiency.

According to Kawasaki, the world’s electrical power consumption is expected to increase in the coming years, with much of the increase occurring in Southeast Asia, which is seeing rapid economic growth. In addition to conventional natural gas output, the number of new shale gas supplier countries other than the United States is expected to increase as well. As a result, demand for construction of gas-fired thermal power plants will grow, and the CCPP market is also anticipated to expand in terms of both capacity and regions. In the distributed energy system market, where power producers are introducing new facilities and updating existing ones at an increasing rate due to factors such as expanded use of unstable renewable energy sources, there are marked demands for highly efficient equipment and excellent load responsiveness. Kawasaki’s CCPP should be able to respond to those demands.

In a statement on April 19, 2018, Thales announced that it had reached an agreement with Senegal for the delivery of Ground Master 400 air surveillance radar and SkyView command and control systems. DefenceWeb quoted the firm as saying in a statement, "The Senegalese armed forces are to deploy a state-of-the-art airspace surveillance and control capability."

The statement did not note how many would be delivered.

Senegal will install the radars at the Ouakam Air Base, located in the capital, Dakar. DefenceWeb noted that deliveries are expected to begin sometime next year.

The Senegalese military has imported new military equipment in recent years, buying both new-build and second-hand hardware for its Air Force, in particular. These acquisitions include Mi-24 helicopters, refurbished in Poland, and a contract announced recently for the procurement of four L-39NG aircraft. The L-39NGs, defenceWeb reported, will come equipped with AIM-9L missiles, giving the aircraft the ability to conduct air-to-air missions.

Powering the Avicopter AC352, the engine has been jointly developed and built by Safran Helicopter Engines, Dongan and HAPRI, parts of the Aero Engine Corporation of China (AECC) consortium.

Known in China as the WZ16, it should be certified by CAAC (Civil Aviation Administration of China) in September 2019. The Ardiden 3C/WZ16 will be the first helicopter engine to be certified by both CAAC and EASA.

The Ardiden 3C/WZ16 is a new-generation turboshaft in the 1,700 to 2,000 shp power class. It features a remarkably compact modular architecture, a best-in-class power-to-weight ratio and a low cost-of-ownership. Compared to engines operating in the same power range, it offers ten per cent lower fuel consumption.

Ardiden 3C flight test campaign started in December 2016 with the AC352's maiden flight. Another variant, the Ardiden 3G, has also been selected by Russian Helicopters to power its Ka-62 which made its first flight in May 2017.

Since first ground tests of its two variants, the Ardiden 3 range maturation and certification campaign has accumulated more than 10,000 hours of trials, and will demonstrate a high level of maturity at entry-into-service.

With over 500 engines in operation, China represents a major strategic market for Safran Helicopter Engines. One of every two Chinese-registered helicopters is equipped with a Safran engine or licensed product. This level of business is the result of 40 years of cooperation with industry in China.
