India has introduced stricter Deviation Settlement Mechanism (DSM) rules and heavier financial penalties for renewable energy producers when their actual power supply fails to match their scheduled grid commitments. Set to take effect, these tougher regulations aim to safeguard national grid stability amid booming solar and wind capacity. The new grid regulations have sparked major concern among investors and developers.

India has introduced stricter Deviation Settlement Mechanism (DSM) rules and heavier financial penalties for renewable energy producers when their actual power supply fails to match their scheduled grid commitments. Set to take effect, these tougher regulations aim to safeguard national grid stability amid booming solar and wind capacity. 
The new grid regulations have sparked major concern among investors and developers. 
Specific details and impacts of the updated framework include:- 

Stricter Tolerance Bands: -
The Central Electricity Regulatory Commission (CERC) has tightened the allowable error limits for scheduled power generation, bringing renewable energy producers under the same strict forecasting regimes as conventional power plants. 
Revenue Projections: -
Industry groups estimate that the strict new penalties could reduce revenues for solar projects by about 11% . Wind farms are expected to take an even harder hit, potentially seeing revenue cuts of up to 48% due to weather-dependent generation variability. 
Impact on Returns: -
Analysts project that Internal Rates of Return (IRRs) for wind projects could drop by 1.5 percentage points, and by 1.2 percentage points for hybrid (solar/wind) projects. 
Infrastructure Bottlenecks: -
Developers point out that India still lacks the real-time weather forecasting technology and battery storage infrastructure required to meet these tight scheduling standards. In the meantime, companies are investing in upgraded automated weather stations and advanced satellite data to bridge the forecasting gap.
Despite industry alarm, grid operators and the power ministry maintain that these new rules are critical for maintaining grid discipline, mitigating transmission curtailments, and preventing grid overloads as the country races toward its target of 500 gigawatts of non-fossil fuel capacity by 2030. 
India's tougher grid rules unsettle investors, test clean energy ambitions
 India's push to tighten power grid discipline is colliding with its clean energy ambitions as tougher rules for solar and wind projects..

Hydrogen at home — It's the end of solar and wind power

  Hydrogen at home — It's the end of solar and wind power         Statement "1000 pounds" per day of hydrogen at home — It's the end of solar and wind power in the world" is not accurate.     While hydrogen can be produced from renewable energy sources like solar and wind power, it's not a replacement for those sources themselves. Hydrogen production via electrolysis, using renewable electricity, is a promising avenue for decarbonization, but it doesn't negate the need for solar and wind power as direct energy sources.  Cause behind its is as under. Hydrogen as an Energy Carrier:-     Hydrogen is an energy carrier, meaning it stores energy produced elsewhere (like from solar or wind) and can be used to power fuel cells or for other applications.  Electrolysis:-     A key method of producing "green" hydrogen involves using electricity from renewable sources (like solar and wind) to split water into hydrogen and oxygen throu...

Solar Generation in Night hrs

How to get get Solar generations in Night        While standard solar panels cannot generate electricity at night,     New technologies are being developed to address this limitation.      These advancements focus on harnessing the earth's heat or using infrared radiation emitted by the Earth to generate power, potentially creating 24-hour renewable energy sources.  Key Concepts and Technologies :- 1) Anti-Solar Panels (Thermo-radiative Cells):- How they work:-    These panels, also known as thermoradiative cells, work in reverse of traditional solar panels. Instead of absorbing sunlight, they emit infrared radiation into space, which is then converted into electricity.    Nighttime energy:-     They can generate electricity from the difference in temperature between the panel and the surrounding environment, essentially converting the heat escaping into space back into usable power.  Potential:-  ...

State-wise carbon emissions in India show a concentration in western and southern states, with byd as major emitters, particularly from the manufacturing and energy sectors. The highest total CO2 emissions have been linked to states like Maharashtra, Andhra Pradesh, Uttar Pradesh, Gujarat, Tamil Nadu, and West Bengal, though the specific ranking can vary depending on the data year and the specific pollutants included.
