The company has won Gaskomplektimpex Ltd. tender to sign contracts for the delivery of power equipment. Under the project the company will deliver 9 power stations with the total capacity 93 MW for compressor stations of Bovanenkovo-Ukhta gas pipeline. Gas engine power plants will satisfy all power requirements of compressor stations. Each power plant will consist of 5-7 gas engine power units rated at 1.1 - 1.5 MW each and stand-by diesel power plants with the capacity 0.6 - 1 MW each.
By the time of being Zvezda-Energetika has delivered more than 310 power units with the total capacity 214 MW for Gasprom JSC projects.  The commissioning of the gas-main pipeline is scheduled for the end of 2011.

Mitsubishi Heavy Industries, Ltd. (MHI) has developed and begun operational verification testing of the "MACH II-SI," a new gas engine featuring enhanced energy efficiency and reliability. The MACH II-SI was developed based on the company's existing "MACH-30G," which many units have been sold in Japan; but whereas the forerunner uses a "micro-pilot ignition" system, the new MACH II-SI adopts a spark ignition (SI) system that eliminates the need for auxiliary liquid pilot fuel such as light oil.
In developing MACH II-SI, MHI focused on further enhancement of the efficiency leveraging its abundant experience accumulated in its existing engines. As a result, the new engine has achieved efficiency – combining power generation and heat energy recovery via steam – of 66.1%*, the world's highest level among 6,000 kilowatts (kW) class engines, in which electric power generation efficiency has been improved by 1 percentage point. MHI expects the MACH II-SI series, which power output ranges from 3,650 kW to 5,750 kW, will significantly contributes to increasing needs for CO2 emission reduction.
To enhance overall efficiency, MHI focused on enhanced heat recovery in steam generation and effective utilization of exhaust gas energy. The company also has shortened lead-time to reach full load after engine start by 50%, which contributes to enhance load-following capability. In order to boost power generation efficiency, MHI redesigned the combustion chamber, including the cylinder cover and piston. By optimizing formulation of the fuel-air mixture, as well as improving the pre-chamber's shape and fuel-air mixture ratio, the company has raised combustion efficiency and reduced thermal loss.

Wärtsilä has been awarded contracts to supply two power plants to be installed in the Madang region of Papua New Guinea. The orders were placed in May and June by China ENFI Engineering Corporation with one plant to be located at the Ramu nickel mine, and the other at the nickel refinery in the port area. The Ramu nickel mine is being developed by the China Metallurgical Group (MCC), a Chinese state-owned mining and natural resources exploitation concern, and its partners.
The combined output of the two power stations will be in excess of 90 MWe and will supply electricity to the entire nickel mining and refining project facilities. This will complement the existing 120 MWe of power already supported by Wärtsilä in the region.
Wärtsilä is contracted to supply the equipment together with an engineering and technical assistance package. The refinery installation will include a heat recovery system with the waste heat being utilized in the complex refinery process. Both installations are scheduled to be completed before the end of 2009.

The micro-CHP is an innovative power and heating system for single and multi-family homes. It is also one of the most efficient methods of energy generation: the fuel is transformed into both electrical energy and heat – usually in the form of steam and hot water. Consequently, more than 90 percent of the energy contained in the fuel is utilized – in comparison with just 38 percent for electrical generation by a power station.
Not only can the micro-CHP supply a four-person household with its heat, it is also able to meet two-thirds of its electricity requirements. Excess electricity generated is supplied to the public power grid. Siemens Building Technologies developed all the control electronics for this novel heating system and is working with manufacturers of condensing boilers such as Viessmann, Vaillant, Remeha B.V. and the Baxi Group.
The functionality of the micro-CHP is relatively simple: A gas-fired Stirling engine is integrated into the wall-mounted boiler.  The temperature difference between the heat and cold water is used to generate electricity. The current design makes it possible to produce a maximum of 1 kW of electrical energy, of which up to 900 W can be used directly. If the household consumes less, the excess is fed into the power grid of the energy supplier.
