Coal-based capacity remains the largest contributor to power generation in India with a share of 71 per cent in 2020-21, supported by a large coal reserve in the country. Despite the decline in its share […]
Flue gas desulphurisation (FGD) systems are a must have coal-based plants as they help comply with the stringent environmental norms notified by the Ministry of Environment, Forest and Climate Change (MoEFCC) on December 7, 2015. […]
A flue-gas desulphurisation (FGD) system is installed in the boiler of a thermal power plant (TPP) to absorb the sulphur content from the emissions, thereby reducing sulphur dioxide (SOx) emissions. The cost economics of FGD […]
In thermal power plants (TPPs), the combustion of coal converts a large portion of the nitrogen bound in coal to form oxides of nitrogen (NOX) such as nitric oxide, nitrogen dioxide and nitrous oxide. The […]
In a significant development, the Ministry of Power (MoP) has issued new rules allowing automatic pass-through of costs upon occurrence of a change in law event. The automatic pass through will be computed based on […]
The particulate matter (PM) emissions in a thermal power plant (TPP) can be reduced and controlled by the installation of emission controlling devices such as electrostatic precipitators (ESPs), fabric filters and cyclone separators. Empirical data […]
Among the industrial consumers of water, thermal power plants (TPPs) are the largest ones. It is estimated that TPPs account for nearly 88 per cent of industrial water consumption in the country. Moreover, 48 per […]
NHPC Limited, the largest hydropower developer in the country, has played a pivotal role in the sector for decades, adding about 7,000 MW in the past 45 years. It is now gearing up to double […]
In view of the large renewable energy capacity addition planned for the next few years, pumped storage hydropower projects are expected to play a vital role in providing balancing power. THDC India Limited (THDCIL), which […]
Coal-based power is the mainstay of the Indian electricity sector, accounting for 55 per cent of the installed power capacity. However, Indian coal has a high ash content of 30-45 per cent, resulting in huge […]
Ash handling technologies help in collecting, conveying, storing and loading different types of residual ash generated by coal-based power plants. The most common types of ash, resulting from the combustion of coal, lignite, wood and […]
The combustion of coal in thermal power plants (TPPs) produces finely divided particles known as fly ash as a by-product. It consists of typically spherical particles of 10-100 microns each. Its primary constituents are oxides […]
State-owned generation utility, Gujarat State Electricity Corporation Limited (GSECL), plays a strategic role in meeting Gujarat’s power needs. It has built a sizeable power generation portfolio of more than 6 GW, comprising a mix of […]
While 2020 was a grim year defined overwhelmingly by the Covid-19 pandemic, it had certain upsides as well. One of the most significant developments during the year in terms of climate policy was that a […]
The recent coal mining auction, held in November 2020 under the commercial coal mining policy, saw aggressive bidding by domestic players, with 19 blocks being successfully auctioned, which are expected to generate total revenues of […]
India is expected to achieve a total installed power generation capacity of 830 GW by 2030, half of which will be coal based. Coal-fired power plants, however, are big contributors to emissions of sulphur oxide […]
India’s energy mix consists primarily of electricity based on fossil fuels, which account for 61.9 per cent share, of which coal comprises 53.4 per cent. This, however, is set to change in the coming years, […]
The Covid-19 pandemic and the subsequent lockdown have led to a significant reduction in energy demand, besides changes in the sales mix and the load curve. In the power generation segment, this has resulted in […]
In India, coal/lignite-based thermal power plants (TPPs) are the backbone of power generation and hence, generation of large amounts of fly ash is a common phenomenon. Additionally, Indian coal is of a lower grade with […]
