We&#8217;re breaking down exactly how this ancient technology works, and how it&#8217;ll play a critical role in Australia&#8217;s transition to renewable energy sources.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How it works<\/h2>\n\n\n\n<p>Humans have harnessed the power of water to drive machines since the dawn of time,&nbsp;with the ancient Greeks first&nbsp;using&nbsp;water-driven&nbsp;mill stones to grind wheat into flour.&nbsp;Hydropower&nbsp;was first used to generate electricity in the late 1880s and now supplies over 16% of the world\u2019s electricity.&nbsp;&nbsp;<\/p>\n\n\n\n<p>There are three types of hydroelectric power&nbsp;stations; conventional, pump&nbsp;storage and run of river.&nbsp;&nbsp;Each <a href=\"https:\/\/www.originenergy.com.au\/blog\/what-is-electricity\/\">generate electricity<\/a>&nbsp;by passing water&nbsp;from a dam (conventional) or river (run of river)&nbsp;through&nbsp;turbine blades to drive a&nbsp;generator to convert the motion into&nbsp;electricity.&nbsp;In the case of&nbsp;pumped&nbsp;storage hydro,&nbsp;water&nbsp;is pumped&nbsp;from a lower elevation dam to a higher&nbsp;one and&nbsp;this water is&nbsp;released&nbsp;to drive the generator when electricity is needed.&nbsp;&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Giant batteries<\/h2>\n\n\n\n<p>Typically,&nbsp;pump storage plants will move water between a lower and higher dam&nbsp;during the middle of the day when energy from renewable sources like wind and solar&#8217;s&nbsp;plentiful and demand&#8217;s low.&nbsp;The water in the higher dam essentially becomes stored energy, much like a giant battery, ready to be released&nbsp;quickly and for long durations&nbsp;to generate energy when it is needed most.&nbsp;&nbsp;&nbsp;&nbsp;<\/p>\n\n\n\n<p>Like battery storage, pumped&nbsp;hydro will increasingly be used to&nbsp;back up&nbsp;renewable energy sources,&nbsp;stepping in&nbsp;when the sun isn\u2019t shining&nbsp;or the wind&#8217;s not blowing.&nbsp;&nbsp;&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The Shoalhaven pump storage scheme<\/h2>\n\n\n\n<p>Origin\u2019s Shoalhaven pump&nbsp;storage hydro scheme&nbsp;in the NSW Southern Highlands was&nbsp;first&nbsp;commissioned&nbsp;in 1977. The scheme&nbsp;has&nbsp;hydropower stations at Kangaroo Valley and&nbsp;Bendeela&nbsp;with a total&nbsp;generating&nbsp;capacity of 240MW,&nbsp;while the facility\u2019s dams&nbsp;can also&nbsp;supply water to Sydney during times of drought.&nbsp;<\/p>\n\n\n\n<p>The&nbsp;scheme&nbsp;was designed to allow for future expansion, so infrastructure needed to grow the station&nbsp;like space for new pipes and transmission lines are&nbsp;already in place.&nbsp;In 2019 Origin completed an assessment that found it was technically feasible to expand the facility by&nbsp;adding&nbsp;one additional&nbsp;generating&nbsp;unit, or approximately 235MW, of new capacity.&nbsp;<\/p>\n\n\n\n<p>The expansion&nbsp;of Shoalhaven&nbsp;would have the potential to support more renewable energy coming into our National Electricity Market and make it more secure.&nbsp;<\/p>\n\n\n\n<div class=\"wp-block-buttons is-horizontal is-content-justification-center is-layout-flex wp-container-core-buttons-is-layout-1 wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/www.originenergy.com.au\/electricity-gas\/green.html\">Learn about our green energy plans<\/a><\/div>\n<\/div>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>We break down exactly what hydropower is and how it&#8217;s playing a critical role in Australia&#8217;s transition to&nbsp;renewables.<\/p>\n","protected":false},"featured_media":18949,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[108],"tags":[112,46],"oe_author":[],"class_list":["post-17677","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-future-energy","tag-hydropower","tag-sustainability"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.originenergy.com.au\/blog\/wp-json\/wp\/v2\/posts\/17677","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.originenergy.com.au\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.originenergy.com.au\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.originenergy.com.au\/blog\/wp-json\/wp\/v2\/users\/38"}],"replies":[{"embeddable":true,"href":"https:\/\/www.originenergy.com.au\/blog\/wp-json\/wp\/v2\/comments?post=17677"}],"version-history":[{"count":0,"href":"https:\/\/www.originenergy.com.au\/blog\/wp-json\/wp\/v2\/posts\/17677\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.originenergy.com.au\/blog\/wp-json\/wp\/v2\/media\/18949"}],"wp:attachment":[{"href":"https:\/\/www.originenergy.com.au\/blog\/wp-json\/wp\/v2\/media?parent=17677"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.originenergy.com.au\/blog\/wp-json\/wp\/v2\/categories?post=17677"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.originenergy.com.au\/blog\/wp-json\/wp\/v2\/tags?post=17677"},{"taxonomy":"oe_author","embeddable":true,"href":"https:\/\/www.originenergy.com.au\/blog\/wp-json\/wp\/v2\/oe_author?post=17677"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
