Pumped Storage Hydropower (PSH)
Why in News: The Budget for 2024-25 announced the introduction of a policy aimed at promoting pumped storage projects for electricity storage.
About Pumped Storage Hydropower (PSH)
A type of hydroelectric energy storage system.
Structure:
- Consists of two water reservoirs at different elevations.
Working Mechanism:
- Excess electricity, often from renewable sources like solar and wind or during off-peak hours, is used to pump water from the lower reservoir to the upper reservoir.
- When there is a demand for electricity, water is released from the upper reservoir to the lower reservoir, passing through turbines to generate electricity.
- The system also consumes power when pumping water back to the upper reservoir (recharge).
Operation:
- Operates similarly to conventional hydropower plants but can reuse the same water repeatedly.
- Absorbs surplus energy during low demand periods and releases it during high demand.
Capacity:
- The energy storage capacity depends on the size of the reservoirs.
- The power generated is determined by the size of the turbine.
Types of PSH:
- Open-loop: Has either an upper or lower reservoir continuously connected to a naturally flowing water source like a river.
- Closed-loop: An ‘off-river’ site that produces power from water pumped to an upper reservoir without significant natural inflow.
Open Market Sale Scheme (OMSS)
Why in News: The Centre has recently permitted state governments to purchase rice directly from the Food Corporation of India (FCI) without needing to participate in the e-auction process under the open market sale scheme (domestic).
About Open Market Sale Scheme (OMSS)
Purpose:
The Food Corporation of India (FCI) sells surplus food grains, particularly wheat and rice, from the central pool to traders, bulk consumers, and retail chains at predetermined prices. This is done alongside maintaining buffer stocks and fulfilling the National Food Security Act (NFSA) and Other Welfare Schemes (OWS) requirements.
Mechanism:
Sales are conducted through e-auctions where bidders can purchase specified quantities.
- For wheat: Bidders can bid for a minimum of 10 metric tons (MT) and a maximum of 100 MT.
- For rice: Bidders can bid for a minimum of 10 MT and a maximum of 1000 MT.
State Procurement:
- States can procure food grains through OMSS without participating in auctions, for their specific needs beyond their central pool allocations.
Objectives:
- Enhance food grain supply during lean seasons to ensure food security.
- Moderate open market prices and control inflation, especially in deficit regions.
Surrogate Advertising
Why in News: The Union Health Ministry has recently directed both the Sports Authority of India (SAI) and the Board of Control for Cricket in India (BCCI) to implement measures to prevent sportspersons from endorsing tobacco or alcohol products through surrogate advertising.
About Surrogate Advertising
- Definition: Surrogate advertising involves promoting one product by mimicking the brand image of another product from the same brand.
- Purpose: Used to advertise products that cannot be directly promoted due to legal or social restrictions.
- Types: Surrogate goods may either resemble similar commodities or be entirely different products. Companies use this technique to promote their products by disguising them under another product with the same brand name.
- Applications: Commonly employed for advertising liquor and tobacco-related products, often through alternative products like music CDs or soda.
- Prevalence: In India, surrogate ads are widespread and appear across various media platforms.
- Objective: Aims to subtly and legally convey the brand message, allowing the audience to associate the disguised product with the original brand. This process is also known as “brand extension.”
Disaster Management (Amendment Bill), 2024
Why in News: The Government has recently presented the Disaster Management (Amendment) Bill 2024 in the Lok Sabha.
About Disaster Management (Amendment) Bill, 2024
- Objective: Aims to amend the Disaster Management Act, 2005, to enhance disaster management effectiveness.
- Urban Disaster Management Authority: Proposes the creation of an “Urban Disaster Management Authority” for State capitals and major cities with municipal corporations, excluding Delhi and Chandigarh.
- Authority and Planning: Empowers the National Disaster Management Authority (NDMA) and State Disaster Management Authorities to develop disaster plans at the national and state levels, replacing the previous role of the National and State Executive Committees.
- Expert Appointments: Grants NDMA the authority to appoint necessary experts and consultants to support its functions.
- Disaster Database: Establishes a national and state-level disaster database, covering disaster assessments, fund allocations, expenditures, preparedness plans, risk registers, and other relevant matters, as determined by the Union government.
- Recognition of Existing Bodies: Provides statutory recognition to bodies like the National Crisis Management Committee and the High-Level Committee.
- State Disaster Response Force: Introduces provisions for State Governments to establish a “State Disaster Response Force.”
- New Section 60A: Adds a new Section 60A to enable both Central and State Governments to direct individuals to take or avoid specific actions to mitigate disaster impacts, with penalties for non-compliance capped at ₹10,000.
Schistura sonarengaensis
Why in News: A team of scientists has recently discovered a new species of loach, called Schistura sonarengaensis, in the South Garo Hills district of Meghalaya, close to the Bangladesh border.
About Schistura sonarengaensis
A newly discovered species of loach.
Habitat:
- Found in cave-dwelling populations within the Barak-Surma-Meghna drainage in the South Garo Hills district of Meghalaya.
Description:
- Distinguished by prominent eyes and 13-26 vertically elongated to circular black blotches on a grayish-black mid-lateral stripe, set against a dull white or pale-beige body.
Adaptations:
- Lacks typical subterranean adaptations like complete eye loss or pigmentation loss.
- Shows reduced pigmentation compared to surface-dwelling relatives but is not blind.
Comparison:
- Retains prominent eyes and differs from other Schistura species in the Barak-Surma-Meghna and adjacent river drainages of northeast India, except for Schistura syngkai.
