 Codensa Is Moving Onto A Smart Electrical Energy System

• Remote controls allow the detection and isolation of failure zones more accurately and in less time. • This modernization will lead to fewer failures, their duration will be shorter and the number of customers affected by the failures will be smaller.

With an investment of nearly COP 238,000 million, CODENSA will carry out the largest electrical grid modernization and remote control project of its kind in the country, which will mark a significant breakthrough toward the construction of a smart system.

The installation of the remote control system on the electrical grid in Bogotá and Cundinamarca will allow a more efficient operation of the grid in the event of service failures, indicate more accurately the location where the failure occurred in a circuit, and reduce the number of customers affected by the failure, which will be reflected in the reduction of repair time and the number of repairs.

The project, which began in the second semester of this year, consists of installing of nearly 3,800 components on 558 circuits (of CODENSA's 983 circuits), and the reinforcement of the distribution grids thereof, which were selected and prioritized in accordance with their criticality due to incidents or failures. These European-made remote control devices, equipped to offer the greatest possible levels of functionality in accordance with the characteristics of CODENSA's energy system, will allow the sectioning of circuits in segments of an average of 700 customers and the remote operation of a large part of the service output from the Control Center.

The modernization, which will be completed in 2018, will generate a reduction of approximately 33% in failure duration and 3 times the frequency thereof.

“With this investment, the Company has reaffirmed its commitment to improving the quality of service and modernizing the operation by implementing the latest technology available on the market,” said CODENSA's CEO, David Felipe Acosta.

Nearly 190 people are involved in the project, including engineers, architects, electricians and the logistics staff, who have managed to make progress in the execution thereof rated at 106% higher than scheduled for the project.

This year, 447 components have been installed in Bogotá as well as the rural area of Cundinamarca, which is 11% of the project total and has managed a reduction of approximately 7 minutes on average per failure.

HOW IT WORKS

BEFORE REMOTELY CONTROLLED SYSTEM
The medium voltage failure occurs and the Control Center receives a warning on the circuit with the problem. A failure occurs and a warning is received by the Control Center, indicating the location of the failure in the circuit.
The Control Center sends a crew to the site to go over the circuit where the failure occurred and identify the exact site. The Control Center sends a crew to the exact site where the failure has occurred in the circuit, thus decreasing the time to locate it.
The Control Center cannot restore service to customers until the crew sent to the site finds the exact location of the failure and isolates it. On average, a circuit serves 5,000 customers. The Control Center restores service for the clients of the circuit that are not in the failing segment. On average, the service is expected to resume for 4,300 customers, affecting only 700 customers per segment, which are the ones that are in the failure location.

MOVING ONTO A SMARTGRID

This project is the first step toward what is currently called "smartgrids" and it will be one of the main pillars to achieve smart energy management, one of the components of smart cities.

The term "smart cities" refers to a type of urban development based on sustainability, where social investment, human capital, communications and infrastructure coexist harmoniously with sustainable economic development, supported by the use and modernization of new technologies (ICT), efficient public utility infrastructures and smart energy management, resulting in better quality of life, citizen comfort and the cautious management of non-renewable natural resources.
