Both systems can <strong>share central infrastructure such as the grid connection and the transformer<\/strong>. Under certain conditions, this can simplify the grid connection process compared to a fully standalone battery storage project. Whether a new or amended grid connection application is required depends on the specific project and the requirements of the responsible grid operator.   <\/p>\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why-Battery-Storage-Systems-Are-Becoming-More-Important-in-Co-Location-Facilities\"><\/span>Why Battery Storage Systems Are Becoming More Important in Co-Location Facilities<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n<p class=\"wp-block-paragraph\">By their very nature, renewable energy sources feed a particularly large amount of electricity into the grid when there is plenty of solar or wind energy available\u2014which often coincides with output from many other plants. This leads to a growing number of hours with low or even negative electricity prices, during which feeding power into the grid is hardly worthwhile. A battery storage system connected to the same grid connection can <strong>temporarily store excess energy<\/strong> and sell it at a later, more economically attractive time.  <\/p>\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What-types-of-co-location-models-are-available-for-battery-storage\"><\/span>What types of co-location models are available for battery storage?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n<p class=\"wp-block-paragraph\">In practice, two basic forms can be distinguished:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Stand-alone operation:<\/strong> The storage system uses only the available technical capacity of the existing grid connection for its own feed-in and feed-out, independent of the generation plant<\/li>\n\n\n\n<li><strong>&#8220;True&#8221; co-location:<\/strong> The storage facility and the generation plant are operated in close technical and economic integration, for example through joint optimization of power feed-in<\/li>\n<\/ul>\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Regulatory-Requirements-for-Co-Location-Projects\"><\/span>Regulatory Requirements for Co-Location Projects<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/be-storaged.de\/en\/co-location\/\" title=\"Co-location: Storage at the Grid Connection Point for Solar and Wind Farms\"><u>Co-location projects<\/u><\/a> can be implemented, among other things, as part of the <strong>EEG innovation tenders<\/strong>, which provide targeted funding for combined generation and storage facilities.

They enable operators of solar and wind farms to market electricity in a way that better matches demand, make better use of existing infrastructure, and tap into additional revenue potential. In this way, co-location can make an important contribution to the economic development of existing and new renewable energy facilities. Given the growing expansion of renewable energy, limited grid connection capacities, and increasing price fluctuations, co-location is likely to become even more important for plant operators in Germany.   <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Co-location refers to the shared use of a grid connection point by a renewable energy generation facility and a battery storage system.
