By accessing the tool directly here on our website, you can <strong>try out for yourself what effect battery storage has<\/strong>.<\/p>\n\n\n\n<div class=\"wp-block-buttons is-content-justification-center is-layout-flex wp-container-core-buttons-is-layout-fe48e5de wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/sonne-sammeln.de\/en\/pv-wissen\/grosse-batteriespeicher\/?bricks_preview=1791541162#simulator\" target=\"_blank\" rel=\"noopener\">Go to the simulator<\/a><\/div>\n<\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>A 'what-if' scenario<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The simulator is not a forecast. It performs calculations based on: <strong>What would the electricity price have been on a particular day if there had been more battery storage?<\/strong> To do this, it uses the actual buy and sell bids from the daily electricity exchange. In addition, a desired number of battery storage units is specified. These charge when electricity is cheap and discharge when it is expensive.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>This is how the simulator works:<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Please select:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Battery performance:<\/strong> from 0 to 20 gigawatts<\/li>\n\n\n\n<li><strong>Retention period:<\/strong> from 2 to 6 hours<\/li>\n\n\n\n<li><strong>Market scenario:<\/strong> with or without a response from power stations and neighbouring countries<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The simulator then shows, for every quarter of an hour, how the electricity price on the exchange would have changed \u2013 and when the batteries would have been charging or discharging.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>What you can see:<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The diagram shows the actual electricity price (red line) and the simulated price with battery storage (purple line). Also shown are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>the total load (total electricity consumption)<\/li>\n\n\n\n<li>Solar and wind (both offshore and onshore) feed-in potential<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The data is updated daily and is available for download.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>What batteries do:<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Battery storage systems smooth out price fluctuations: they store cheap electricity and release it again at more expensive times. This reduces price spikes, makes negative prices less common and increases the value of solar power. The simulation for 2025 shows that, with 20 gigawatts of additional battery capacity and a storage duration of two hours, the average price difference between the cheapest and most expensive quarter-hour of the day would have fallen from 130 to 53 euros per MWh.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Important to know:<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Battery storage systems do not generate electricity. They simply shift it from times when there is a surplus of electricity to times when there is a shortage. They are very effective at smoothing out the daily price and demand peaks. However, they cannot bridge long periods of low sunlight on their own. We can safely navigate periods of low wind and low sunlight using a range of technologies that are already available today \u2013 find out more in our fact sheet on periods of low wind and low sunlight.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The simulator analyses electricity trading on the previous day, known as the day-ahead market. Other benefits of batteries \u2013 such as in intraday trading, for balancing energy or for the electricity grid \u2013 are not included.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Why the simulator is important:<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The electricity price simulator brings the debate on battery storage to life. Politicians, business leaders, the media and members of the public can see for themselves what impact increased storage capacity might have on electricity prices \u2013 based on real market data.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Further information on the simulator and on Energy Charts in general is available at the <a href=\"https:\/\/www.energy-charts.info\/index.html?l=de&amp;c=DE\" target=\"_blank\" rel=\"noreferrer noopener\">Fraunhofer ISE\u2019s Energy Charts website<\/a>.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>","protected":false},"excerpt":{"rendered":"<p>Try it out for yourself on the simulator now and see what a difference battery storage makes!<\/p>","protected":false},"author":9,"featured_media":8148,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[],"class_list":["post-10671","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news"],"acf":[],"_links":{"self":[{"href":"https:\/\/sonne-sammeln.de\/en\/wp-json\/wp\/v2\/posts\/10671","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/sonne-sammeln.de\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/sonne-sammeln.de\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/sonne-sammeln.de\/en\/wp-json\/wp\/v2\/users\/9"}],"replies":[{"embeddable":true,"href":"https:\/\/sonne-sammeln.de\/en\/wp-json\/wp\/v2\/comments?post=10671"}],"version-history":[{"count":7,"href":"https:\/\/sonne-sammeln.de\/en\/wp-json\/wp\/v2\/posts\/10671\/revisions"}],"predecessor-version":[{"id":10687,"href":"https:\/\/sonne-sammeln.de\/en\/wp-json\/wp\/v2\/posts\/10671\/revisions\/10687"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/sonne-sammeln.de\/en\/wp-json\/wp\/v2\/media\/8148"}],"wp:attachment":[{"href":"https:\/\/sonne-sammeln.de\/en\/wp-json\/wp\/v2\/media?parent=10671"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/sonne-sammeln.de\/en\/wp-json\/wp\/v2\/categories?post=10671"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/sonne-sammeln.de\/en\/wp-json\/wp\/v2\/tags?post=10671"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
