Power quality and reliability are two important aspects of an electrical power supply system. Therefore, the effective measurement of supply quality is crucial to track the sources of interruptions and enable the comparison of power […]
Power quality (PQ) issues are present in every electric system. PQ problems range largely from supply interruptions and harmonic distortions to transients and imbalances in voltage and current, flickers, voltage sags and swells, frequency excursions […]
The country’s power distribution utilities are grappling with the challenge of high aggregate technical and commercial (AT&C) losses coupled with an increasing power demand. These losses have a significant impact on the operational performance and […]
The role of metering in India has evolved significantly over the years. Besides helping utilities in energy accounting and revenue management, it plays a crucial role in the reduction of power losses, integration of renewable […]
Accurate metering and billing, and better load management are the top priorities for power distribution utilities. Therefore, they have implemented advanced metering infrastructure (AMI) and adopted automatic meter reading (AMR). AMI allows two-way communication with […]
With growing technological advancements, consumer meters have become a storehouse of relevant information, allowing utilities to enhance operational efficiency. Meter data management systems (MDMSs) help in consolidating the data from meters. These systems are used […]
Net metering can play a key role in the uptake of rooftop solar installations. India has a 100 GW solar capacity target by 2022, of which 40 GW is to come from rooftop solar and […]
Meter testing is done to assess the quality of meters to ensure their reliability. Meeting the established technical and functional standards requires testing to be undertaken at various stages. As meters of different technologies and […]
Apart from being the largest source of electricity supply in the country, with over 75 per cent share in the total power generation, coal is also the largest contributor to industrial emissions. In India, the […]
Flue gas desulphurisation (FGD) is one of the key technology solutions used at thermal power plants (TPPs) to cut down emissions. It helps in reducing suspended particulate matter (SPM) emissions along with sulphur oxide (SOx) […]
The emission control norms notified by the Ministry of Environment, Forest and Climate Change in December 2015 have narrowed the particulate matter (PM) emission limits for coal-based power plants considerably. As against the earlier range […]
Emissions from coal combustion include particulates, sulphur oxides (SOx), nitrogen oxides (NOx) and high levels of CO2. Emission control can be undertaken by coal-based power plants at various levels. The pollutant ingredient can be removed […]
Water is one of the key input requirements for thermal power generation. It is required for various uses like process cooling in the condenser, ash disposal, removal of heat generated in plant auxiliaries and various […]
Before the new environment norms were put in place in December 2015, there were no rules to control nitrogen oxide (NOx) emissions at thermal power plants (TPPs) in India, despite the fact that coal-based power […]
Indian coal has a high ash content of 35-45 per cent, and its combustion causes significant air pollution. The practice of surface mining or open cut mining for coal extraction in India contributes to the […]
Supervisory control and data acquisition (SCADA) is a system for acquiring and analysing information obtained from numerous devices placed on the electrical grid. A SCADA system can monitor and control hundreds to hundreds of thousands […]
Launched in November 2015 to improve the financial and operational efficiency of state discoms, the Ujwal Discom Assurance Yojana (UDAY) has been a game changer in the power distribution segment. Even though the discoms have […]
Cloud computing technology is fast gaining traction in the country. As per industry estimates, the public cloud services market in India has seen phenomenal growth over the past two years, reaching $1.8 billion in 2017, […]
