Whisper 200

The Whisper 200 is one of the most widely recognized Micro Wind Turbines in the world and has its roots in the Whisper turbine design from SWPP (Southwest Wind Power). It has been type tested & certified as per IEC 61400 for power performance & for safety & functional test by NIWE (National Institute for Wind Energy) which was formerly known as CWET (Center for Wind Energy Technology, India). This turbine is among the most efficient wind turbines in its class, capable of generating power even at low wind speeds, with a wide range of functionality and applications. Since its initial launch, over ten thousand Whisper 200 units have been installed globally, leaving its mark as a reliable, efficient Micro Wind Turbine

BACKGROUND

Border defense is one of the most critical areas of focus for the government and the armed forces in particular. India is bordered by terrains of vast variety – from the deserts of Thar in Rajasthan to the snow-capped mountains in the north and the dense jungles in the north east – and each of these brings with it its own infrastructure limitations. The military installations in these locations, therefore, face an enormous challenge in the delivery of essential services such as power and water.

The remote locations of these defense installations often result in a lack of access to conventional electricity grids, as it is very difficult to add power infrastructure at these places. As a result, diesel generators become the alternative for generating electricity. Not only is diesel expensive and difficult to transport to these locations, it also poses a serious vulnerability when stored on-site.

THE NEED FOR MORE

With diesel not providing a solution that is secure or feasible in the long run, there was a need for a reliable, sustainable source of energy for defense installations situated in these remote locations, which would require minimal maintenance and was not a security risk.

HOW WE DELIVERED MORE

Working along with the Indian army, we undertook a study of one of their military base camps in Leh (one of the most elevated locations in the world at 18,000 feet above mean sea level) to understand the topography and weather conditions, as well as the area available for installation. Based on this study, a 50 kW WiSH hybrid system was designed, which consisted of a wind farm of 10 Whisper 200 turbines combined with a 40 kW solar PV array. Considering the extreme climatic conditions under which the turbines would be operating, we used alternative materials for some of the critical components to ensure that the system would continue delivering performance through its lifetime. Additionally, we trained the army engineers to maintain the system to minimize the costs and time required for an external service team to travel to this location.

MORE POWER

The 50 kW hybrid solution was installed and commissioned in late 2007, generating over a 100,000 units a year, resulting in savings of approximately 37,800 litres of diesel and Rs. 25 lakhs annually. More importantly, it has provided the army camp in Leh with a reliable and consistent source of power, even in extreme climatic conditions, without a single instance of breakdown. Since then, we have installed a further 60 kW of capacity and a standalone 3 kW wind farm for the Indian army in Leh and Ladakh.
