Solución de transporte eléctrico y su infraestructura de carga asociada, como estrategia para aumentar la carga eléctrica en las zonas comunes de una edificación comercial en Bogotá

Abstract

Un renowned commercial architectural complex located in Bogotá D.C., hereinafter referred to as "the tower," is certified with American LEED standards for energy and environmental sustainability. Currently, the common area facilities of the tower consist of two 1250 and 2000 kVA transformers, with the first one located in the basement and the second in the middle of the tower, whose current load is less than 12% of its capacity, a situation identified in a load capacity study conducted in January 2022. Additionally, the common area account consumes an average active energy value close to 55 MWh but remains under the regulated tariff regime. The formulated project proposes the development of an electric transportation solution and the conceptual and basic engineering of its Electric Vehicle Charging Center as a strategy to increase the load and energy demand in the tower's common areas and consequently meet the requirements to transition to an unregulated tariff regime. It also brings other benefits such as improving the charging conditions of the facility, strengthening the sustainability policy, providing a new sustainable mobility service for tenants and visitors, which in turn constitutes a new business unit for the administration. The study's development has identified the necessary requirements for the transition from a regulated to an unregulated user, establishing consumption thresholds and regulatory conditions. In addition, an optimal operational scheme for electric vehicle charging has been designed and characterized, maximizing efficient energy use and minimizing costs. The technical design of the charging center has been developed in accordance with regulations and standards, ensuring safety and efficiency in operation. Overall, the project demonstrates the viability of using electric vehicles in a sustainability approach by increasing the energy demand of a residential tower and transitioning to an unregulated tariff regime.
