NEWS – Central Electricity Authority Approves Hydro-Pumped Storage Plant in Karnataka

PROJECT DETAILS

– Capacity: 2,000 MW

– Developer: KPCL (Karnataka Power Corporation Limited)

– Investment: Rs 8,005 crore

PROJECT DESCRIPTION

– Pumped Storage Plant: Involves two reservoirs, one on top of a hill and another at the bottom

– Process: Excess electricity is used to pump water uphill to the upper reservoir, and when demand spikes, water is released to the lower reservoir through a turbine, generating power

– Features: Eight hydropower plants with capacities of 250 megawatts each, underground tunnel, and eight power-generating units

SIGNIFICANCE AND BENEFITS

– Energy Security: Project prioritized to ensure energy security of the country

– Grid Stability: Plant will play a crucial role in balancing grid stability and meeting peak power demands

– Reliable Solution: Offers a reliable solution for storing and generating electricity efficiently

HOW IT WORKS

– During off-peak hours, excess energy is used to pump water from the lower reservoir to the upper reservoir.

– During peak hours, water is released from the upper reservoir through the penstock to the pump-turbine.

– The pump-turbine generates electricity as the water flows through it.

– The electricity is transmitted to the grid and distributed to consumers.

DISADVANTAGES

–  High Initial Costs: Requires significant investment for construction and infrastructure.

– Location-Specific: Requires a suitable location with a significant height difference between the upper and lower reservoirs.

– Environmental Impact: Can have environmental impacts like altering natural water flows and affecting aquatic ecosystems.
