When the turbines arrived in 2012, the group used to have unscheduled shutdowns every three months. Learning along the way, in April this year we achieved the record of more than 22 months of continuous operation without interruptions<\/strong>. <\/p>\n

Records like this speak of the good performance of the Power Group and, according to Eric Bustos, our IMG Electrical Specialist<\/strong>, we can compare ourselves to an international level.[\/et_pb_text][\/et_pb_column][et_pb_column type=”1_4″ _builder_version=”4.19.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_image src=”https:\/\/alma.loadingediciones.cl\/dev\/wp-content\/uploads\/2024\/09\/WhatsApp-Image-2024-09-03-at-10.47.18-e1725386082270.jpeg” title_text=”WhatsApp Image 2024-09-03 at 10.47.18″ _builder_version=”4.19.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][\/et_pb_image][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”2_3,1_3″ _builder_version=”4.19.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”2_3″ _builder_version=”4.19.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_image src=”https:\/\/alma.loadingediciones.cl\/dev\/wp-content\/uploads\/2024\/09\/SAIDI-Europa-1_page-0001.jpg” title_text=”SAIDI Europa (1)_page-0001″ _builder_version=”4.19.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][\/et_pb_image][\/et_pb_column][et_pb_column type=”1_3″ _builder_version=”4.19.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text _builder_version=”4.19.1″ _module_preset=”default” text_text_color=”#000000″ text_orientation=”justified” global_colors_info=”{}” theme_builder_area=”post_content”]This is because there are indicators such as the System Average Interruption Duration Index (SAIDI) that show the energy interruption that reaches users. The closer the number is to 0, the lower the interruption and the better the experience for the consumer. Globally, Chile has a SAIDI of 10, but ALMA registers indicators close to zero, comparable to the best performances in Europe, such as Germany and the Netherlands. <\/p>\n
