When electricity demand is high, the water is released back down, passing through turbines to generate power.\n<ul class=\"wp-block-list\">\n<li>It essentially\u00a0<strong>functions as a \u201cbattery\u201d for the power grid<\/strong>, storing energy and releasing it as needed.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>PSH is a fundamentally simple system that\u00a0<strong>consists of two water reservoirsat different elevations.<\/strong><\/li>\n\n\n\n<li><strong>Working<\/strong>:\n<ul class=\"wp-block-list\">\n<li><strong>When there is excess electricity<\/strong>\u00a0available, such as during off-peak hours or from renewable sources like solar and wind,\u00a0<strong>it is used to pump water from<\/strong>\u00a0the\u00a0<strong>lower reservoir to<\/strong>\u00a0the\u00a0<strong>upper reservoir.<\/strong><\/li>\n\n\n\n<li><strong>When there is a demand for electricity<\/strong>, the\u00a0<strong>water is released from<\/strong>\u00a0the\u00a0<strong>upper reservoir<\/strong>\u00a0back down\u00a0<strong>to the lower reservoir<\/strong>,\u00a0<strong>passing through turbines<\/strong>\u00a0that\u00a0<strong>generate electricity.<\/strong><\/li>\n\n\n\n<li>The\u00a0<strong>system also requires power<\/strong>\u00a0as it pumps water back into the upper reservoir (recharge).\u00a0<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>PSH plants operate much like conventional hydropower plants, except PSH has the\u00a0<strong>ability to use the same water over and over again<\/strong>.\u00a0<\/li>\n\n\n\n<li>The technology absorbs surplus energy at times of low demand and releases it when demand is high.<\/li>\n\n\n\n<li>The\u00a0<strong>energy storage capacity<\/strong>\u00a0of a PSH\u00a0<strong>depends on the size of<\/strong>\u00a0its\u00a0<strong>two reservoirs<\/strong>, while the amount of power generated is linked to the size of the
