engines compress and heat air with a fuel suitable for an . For example, burning natural gas or heats compressed air, and then a conventional engine or the rear portion of a expands it to produce work. can recharge an . The apparently-defunct Compressed air energy storage (CAES) is one of the many energy storage options that can store electric energy in the form of potential energy (compressed air) and can be deployed near central power plants or distribution centers. In response to demand, the stored energy can be discharged by expanding the stored air with a turboexpander generator. [pdf]

Energy can be harnessed directly from the sun, though only slightly during cloudy weather. Solar energy is used worldwide and is increasingly popular for generating electricity or heating and desalinating water. Solar power is generated in two main ways: Photovoltaics (PV),also called solar cells, are electronic devices. . The Solar Resource Atlas of Sri Lanka is an important addition to the existing knowledge on solar resources of Sri Lanka. The First Solar. . The net-metering scheme, which was introduced in 2010 continued to serve the solar PV rooftop industry with large scale implementation across the country. On September 6, 2016, the Government launched an enhanced. Sri Lanka is an island nation blessed with abundant sunshine and solar energy potential. However, solar power currently contributes just 0.4% of the country's electricity mix. [pdf]

A microturbine (MT) is a small with similar cycles and components to a heavy gas turbine. The MT power-to-weight ratio is better than a heavy gas turbine because the reduction of turbine diameters causes an increase in shaft rotational speed. Heavy gas turbine generators are too large and too expensive for distributed power applications, so MTs are developed for small-scale power like electrical power generation alone or as combined cooling, heating, and power (. [pdf]
The micro turbine generator is characterized by high efficiency, low pollution, low cost and modular design. The micro turbine generator power system comprises a gas turbine engine with a high speed electrical generator to provide power of 200kw and to have overall efficiency more than 78% by design of exhaust heat recovery systems.
A microturbine (MT) is a small gas turbine with similar cycles and components to a heavy gas turbine. The MT power-to-weight ratio is better than a heavy gas turbine because the reduction of turbine diameters causes an increase in shaft rotational speed.
In this mode, the microturbine generator is turned on and supplies power to the critical AC bus through LCM2. Typically, this microturbine will also be part of a CHP or CCHP system providing high-efficiency power that can reduce customer energy requirements.
Microturbine generators can be divided in two general classes: Recuperated microturbines, which recover the heat from the exhaust gas to boost the temperature of combustion and increase the efficiency, and Unrecuperated (or simple cycle) microturbines, which have lower efficiencies, but also lower capital costs.
The ARC generator provides smooth DC power output and may be fueled by any heavy fuel, even gas-station diesel. Key Design Features. The ARC micro turbine generator is ultra-compact – the entire device is the size of an ordinary toolbox and weighs just over 10kg.
In other applications, microturbines and engine generators are located off the grid in rural and remote areas where they provide the sole source of power (prime or continuous), or operate in combination with other sources such as photovoltaic or wind turbine installations.
