Amazing: India has electrified 94% of its rail lines, nearly half of this over the last five years. The driver? Reduce reliance on expensive diesel imports and improve energy security.

Rail electrification in India is happening nine-times faster than a decade ago

Around 40,000km have been electrified since 2014, versus 21,801 in all the years prior to 2014. With 94% of lines electrified as of 1 January 2024, Prime Minister Narendra Modi has pledged that Indian Railways will achieve 100% electrification within “a few months”. https://www.energymonitor.ai/tech/electrification/how-india-made-45-of-its-railway-network-electric-in-just-five-years/?cf-view

Check out how a virtual power plant in Ontario roped in 100,000 homes in just six months to balance the grid!

"A virtual power plant program in Ontario, run by Ontario’s Independent Electricity System Operator in partnership with grid-edge flexibility provider EnergyHub, has enrolled 100,000 homes since the program launched in mid-2023.

The Save on Energy Peak Perks program is the fastest growing flexibility program in EnergyHub’s portfolio, and is capable of reducing peak demand by up to 90 MW, according to EnergyHub."

🏡🔋 The U.S. Department of Energy estimates up to 60 GW capacity through VPP programs. It's a game-changer, and with most U.S. utilities jumping on board, the future looks bright! ☀️ https://www.utilitydive.com/news/ontario-vpp-virtual-power-plant-energyhub/706496/

Can pumped-storage hydro solve the challenge of intermittent renewable energy?

We've explored Pumped-storage Hydroelectric (PSH) in our Mega-Batteries series and found the following:

  1. Pumped-storage hydro involves pumping water from a lower reservoir to a higher one during times of low electricity demand and then releasing it back down to generate electricity during peak demand.
  2. This technology provides a flexible and efficient way to store and generate electricity, which is particularly useful for balancing the grid during intermittent renewable energy generation.
  3. Pumped-storage hydro is currently the most widely used form of large-scale energy storage worldwide, and it has numerous benefits, including low operating costs, long lifespan, and high efficiency.
  4. There are also some challenges associated with this technology, such as its high capital costs, environmental impact, and potential limitations in terms of suitable geographic locations.

Pumped-storage hydro is a technology that stores and generates electricity by pumping water from a lower reservoir to a higher one during off-peak periods and then releasing it back down to generate electricity during peak demand.

This technology is widely used worldwide and has several advantages, such as low operating costs, high efficiency, and long lifespan.

Nonetheless, it also presents some challenges, such as high capital costs, environmental impact, and location constraints.
