To improve power supply reliability, Sikkim is focusing on:

The correct answer is: d) All of the above

Sikkim is focusing on upgrading transmission lines, decentralized power generation, and smart grid technologies to improve power supply reliability.

Upgrading transmission lines will help to improve the efficiency of the power grid and reduce the risk of outages. Decentralized power generation will help to reduce the reliance on centralized power plants and make the power grid more resilient to disruptions. Smart grid technologies will help to improve the management of the power grid and make it more efficient.

Here is a brief explanation of each option:

• Upgrading transmission lines involves replacing old or damaged transmission lines with new, more efficient lines. This will help to improve the efficiency of the power grid and reduce the risk of outages.
• Decentralized power generation involves generating electricity at or near the point of use. This can be done through a variety of methods, such as solar panels, wind turbines, and small hydropower plants. Decentralized power generation can help to reduce the reliance on centralized power plants and make the power grid more resilient to disruptions.
• Smart grid technologies involve using digital technologies to improve the management of the power grid. This can include things like using sensors to monitor the grid, using smart meters to track energy usage, and using automation to control the flow of electricity. Smart grid technologies can help to improve the efficiency of the power grid and make it more resilient to disruptions.
