Today, the largest pumped storage power station in the world generates around 3,600 MW (megawatts) of renewable energy – or just over 3.4 terawatt-hours (TWh) per year. That’s enough to power the whole of Botswana each year.
In this article, we’ll take a closer look at the pros and cons of pumped storage, uncovering how it keeps our lights on when we need them most and why it’s not without its challenges.
Pumped storage is a type of large-scale, hydroelectric power generation system that stores excess energy during lower demand times and then releases that energy to generate electricity when it’s needed.
Pumped storage works by using two water reservoirs at different elevations. When there’s excess electricity, that surplus power is used to pump water from the lower reservoir to the upper one.
When electricity demand peaks, it immediately releases the stored water downhill, passing through turbines to generate electricity. It’s essentially a giant energy storage system that helps balance supply and demand for the electrical grid.
Pumped storage is a smart way to save electricity for later when it’s needed most. According to a 2021 research study, the energy cycle between the two reservoirs has a whopping 90% efficiency level – meaning that it only loses 10% of the surplus energy that passes through its turbine.
When it comes to maintaining the balance between electricity supply and demand, pumped storage is a star player. Because of its efficiency in hoarding excess energy, it’s like having a secret energy stash to use whenever there’s a blackout looming.
When electricity demand suddenly skyrockets, pumped storage springs into action with a lightning-fast response time. It can quickly generate power to meet the increased demand and prevent any strain on the electrical grid.
Whenever you’re enjoying a hot shower or binge-watching your favourite show during a peak demand period, you can thank pumped storage for keeping the power flowing smoothly.
With a little TLC, pumped storage infrastructure can be a durable workhorse for decades to come. Regular maintenance is key to keeping the turbines, pumps, and reservoirs in good shape. Just like those ol’ faithful cars that keep ticking along with regular tune-ups.
Constructing the reservoirs and infrastructure for pumped storage can come with a hefty price tag. The need for two carefully located reservoirs, pumps, and turbines, plus the intricate engineering work involved, all adds up to substantial upfront costs. And let’s not forget about the maintenance costs down the line.
Given that gravity plays quite a significant role in pumped storage, it’s not possible to set up shop just anywhere – a pumped storage system needs the right setting, like hilly terrain or mountains and valleys, to work effectively.
Without that elevation difference between the upper and lower reservoirs, the whole energy storage concept goes downhill – and not in a useful way. Obviously, this limits where these systems can be built.
Pumped storage, though highly efficient, isn’t flawless. As mentioned earlier, a small amount of energy (around 10%) sneaks away during the water-pumping stage, a bit like a slow tyre puncture.
Also, over time, sediment can get swept into the reservoirs, reducing their capacity. Again, it’s like a bucket slowly filling up with sand – not ideal, but with proper maintenance, these hiccups can be managed.
Environmental concerns can put the brakes on development, with local communities and environmental groups voicing their apprehension over potential disruptions to local ecosystems – especially local habitats and waterways.
As we wrap up our exploration, we can see that pumped storage has a useful part to play in our quest for grid stability and renewable energy integration. Its efficient energy storage and rapid response to demand spikes are undeniable assets.
However, it’s not without its challenges – the need for the right landscape, environmental concerns, and the upfront price tag all need to be considered. With that being said, it’s all about finding the balance for progress towards our collective net-zero goals.
Pumped storage is a grid-balancing energy storage system which uses surplus electricity to pump water between two reservoirs at different elevations stores excess energy during lower demand times and then releases that energy to generate electricity when it’s needed.
A pumped storage scheme works by using excess hydroelectricity to pump water from a lower reservoir to an upper one, storing energy.During peak demand, the system reacts by releasing its stored water downhill, passing through turbines to generate electricity.
Dams and pumped storage have different functions. Pumped storage is a type of energy storage system that uses two reservoirs at different elevations to store and generate electricity.But the main purpose of dams is to control water flow. They store water for different purposes, like irrigation and drinking water, but can also be used for hydroelectric power generation.
