With hydropower providing 80% of its electricity, Thimphu's facing a modern dilemma: how to store surplus monsoon energy for dry winters. The Thimphu Power Storage initiative, launched in 2023, aims to solve this through cutting-edge battery systems. But wait, isn't Bhutan already carbon-negative?
[pdf] Enter pumped hydropower storage (PSH), the "Swiss Army knife" of energy grids. While solar panels nap at night and wind turbines catch their breath, PSH acts like a giant battery, storing excess energy by pumping water uphill and releasing it when demand spikes.
[pdf] The project will be built as a model of 100 MW HV cascade grid-connected energy storage system, introducing a large-scale energy storage development scheme that can be replicated, promoted and expanded, applicable to the modular and standardized development of large-scale energy storage power stations, and bringing application value and practical reference to related industries.
