The new project, awarded in Transmission Tender No. 01\/2020, increases the reliability, security, and flexibility of the electricity supply for more than two million people in the Metropolitan Region of Sao Paulo.<\/p>\n<p>With an investment expected by <a href=\"https:\/\/www.gov.br\/aneel\/pt-br\" target=\"_blank\" rel=\"noopener\"><span style=\"color: #003087;\">ANEEL<\/span> <\/a>of USD 210 million, the project includes 44.6 kilometers of underground line, 9 kilometers of overhead lines, and a new GIS (Gas-insulated switchgear) substation with a capacity of 800 MVA in Sao Caetano do Sul, in addition to the expansion of two existing substations: Miguel Reale and Sul.<\/p>\n<p>\u201d The Riacho Grande Project is a milestone for the electrical system of the Metropolitan Region of Sao Paulo, not only because of its complexity, but also because of the robustness of the infrastructure delivered.\u201d It is an engineering work designed to accompany the urban and industrial growth of the region, guaranteeing reliability, operational safety, and low environmental impact. &#8220;The energization of this project represents a legacy for millions of people and marks a new performance standard for the metropolitan electrical system,&#8221; said Dayron Urrego, executive director of Projects at ISA ENERGIA in BRAZIL<\/p>\n<p>One of the main differentiators of the Riacho Grande Project is the implementation of the longest underground transmission line built in Brazil, with 44.6 kilometers of extension. This infrastructure connects the Sao Paulo capital with the ABC region, enabling the expansion of new loads and the strengthening of industrial growth.<\/p>\n<p>Underground cables incorporate real-time monitoring technology capable of detecting temperature variations and potential faults, increasing network resilience and facilitating preventive maintenance. The works were conducted using construction methods that preserve urban traffic, minimizing the impact on the population.<\/p>\n<p>During its implementation, the project generated around 2,200 direct and indirect jobs and promoted various social and environmental initiatives. Among these are: environmental education programs in public schools in Santo Andr\u00e9 and S\u00e3o Bernardo do Campo; support for urban agriculture initiatives in project areas; and the renovation of the Recanto Vida Nova shelter, which provides care for homeless people.<\/p>\n<p>ISA ENERG\u00cdA in BRAZIL is the country&#8217;s leading energy transmission company, with 34 concessions distributed across 18 states. With more than 1,600 employees, the company transmits around 30% of Brazil&#8217;s electrical energy and approximately 95% in the state of S\u00e3o Paulo. It is a pioneer in the implementation of innovative technologies, such as the first digital and 4.0 substation, the first large-scale battery energy storage system, and the first SSSC-type FACTS system in the Brazilian transmission system.<\/p>\n<p>For any questions or additional information, shareholders may contact our Shareholder Service Center through:<\/p>\n<ul>\n<li>E-mail: <a href=\"mailto:CAA@bancolombia.com.co\">CAA@bancolombia.com.co<\/a><\/li>\n<li>Shareholder service line: +57 (604) 444 72 31<\/li>\n<li>Headquarters: Carrera 48 No. 26 \u2013 85 Piso 1, Torre Sur, Puerta del Rio branch, Medell\u00edn \u2013 Colombia.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>With an investment of USD 210 million expected by ANEEL, the new project strengthens energy security for more than two million people in the S\u00e3o Paulo Metropolitan Region.
