As variable renewables gain ever-larger shares of the grid power supply mix, integrating them on the grid is raising new questions about the best ways to do it. Storage systems are one obvious answer, but their deployment as utility-scale assets is still in the early days. Right now, if a utility-scale solar plant is producing more power than the grid can use, and there isn\u2019t a storage system available to absorb the excess, the standard procedure is to curtail the plant \u2014 just turn it off. It hurts the revenues of plant owners, but at least it won\u2019t damage the grid.<\/p>\n
But now there are some new ways to the problem of integrating more variable renewables: Make them flexible! Instead of always running wind and solar plants full bore, or curtailing them, just turn them down a bit. Or make them completely flexible, able to ramp up and down at will, after deliberately providing enough room on their host grids to allow that.<\/p>\n
Our guest in this episode is an expert on the subject who has helped the California Independent System Operator, or CAISO, think about new, flexible modes of operation for solar plants. It\u2019s a very geeky and oftentimes technical interview, but we know the grid geeks who listen to this show will love it!<\/p>\n","protected":false},"excerpt":{"rendered":"
If utility-scale solar plants could be made to run more flexibly, they could avoid curtailment and play an even larger role in grid power supply.<\/p>\n","protected":false},"author":4,"featured_media":0,"menu_order":0,"comment_status":"closed","ping_status":"open","template":"","meta":{"_acf_changed":false,"footnotes":""},"categories":[111],"tags":[438,647,645,113,643,644,176,650,651,447,648,137,646,64,115,652,649],"class_list":["post-2284","xen_episodes","type-xen_episodes","status-publish","hentry","category-energy-transition-show-podcasts","tag-caiso","tag-colorado","tag-curtailment","tag-dispatch","tag-flexible","tag-flexible-solar","tag-hawaii","tag-integrated-resource-planning","tag-irp","tag-iso","tag-massachusetts","tag-offshore-wind","tag-ramping","tag-solar","tag-storage","tag-tampa","tag-washington-d-c","xen_guests-arne-olson"],"acf":[],"yoast_head":"\n
