Distribution
Reliability and Quality
Technical Losses
Technical losses are inherent to the provision of the service; they occur mainly due to the heating that occurs when electrical energy passes through transmission lines and transformers.
Total Losses
The Total Loss Indicator (TLI) measures the integrated level of loss from the 115 kV level. The total losses correspond to the total energy that is lost due to technical and non-technical losses, the latter representing the energy lost due to improper manipulation of equipment or billing systems.
System Reliability
Maintaining system reliability – so that our clients have a reliable, continuous energy service – means that our efforts are focused on strengthening our network and on the improvement and performance of our assets.
SAIFI, SAIDI and CAIDI Indicators
SAIFI
The System Average Interruption Frequency Index (SAIFI) measures the frequency of power-service interruptions: that is, the number of interruptions that – on average – a client connected to our network receives in a year.
SAIDI
The System Average Interruption Duration Index (SAIDI) measures the duration of power interruptions; that is, the total number of hours per year that a client connected to our network does not have service.
CAIDI
SASB (IF-EU-550a.2) The Client Average Interruption Duration Index (CAIDI) represents the average time required to restore service once the interruption occurs.
Client Average Interruption Duration Index (CAIDI) | Unit of Measure | 2021 | 2022 |
|---|---|---|---|
Valle del Cauca | CAIDI | 1,487 | 1,56 |
Tolima | CAIDI | 1,629 | 2,04 |
Cetsa | CAIDI | 0,834 | 0,72 |
Although there is a deviation in the Indicator, in the course of 2022 ,there were no relevant events in the system that affected our clients.
Smart Meters
Through the Advanced Metering Infrastructure (AMI) Project, and as part of our Loss-Reduction Plan, we installed a total of 2,660 smart meters in 2022, in Valle and Tolima, which allowed us to achieve a cumulative number of 113,373 smart meters connected to our networks.
What is smart metering? It is the latest technology available that allows the Company not only to have a more-accurate record of client consumption, but also to develop new products and services to make the most of the information that is beginning to be collected through these devices.
Benefits for our clients:
- They have a more-precise measurement of their energy consumption.
- They allow the reading and suspension of the service or – if it is suspended and the system registers the payment – we can reconnect it in less time, all this remotely.
- We will be able to detect the damages that appear in the network in less time, which means that we will attend to them in a more agile manner.
- They will show an improvement in the quality of the service, since in the areas to which we have previously brought this technology, we have carried out a remodeling of medium- and low-voltage networks.
Impact of Climate Change
TCFD: Strategy – b) We are aware of the importance of climate change in all of our businesses, which is why we identify new risks that may impact some important aspects of the expansion and operation of the network, including:
- Alteration in the quality of service to our clients, due to heavy rains and strong winds.
- Impact on the stability of the transmission and distribution structures, due to the increase and severity of extreme phenomena, such as tropical cyclones.
- Impact on electrical substations, due to the rise in the sea level and flooding.
- Possible damage to the T&D Infrastructure, alteration of line maintenance activities, difficulty in air access for repair activities in inaccessible sites, alteration in the health of line and substation operators, possible increase in technical energy losses. In addition, forest fires can generate alterations in the operation of lines and substations (interruption of service), due to the increase in the temperature variation, changes in the force and direction of the wind.
However, we also find opportunities and positive results in initiatives implemented, thanks to the anticipation with which action is taken, driven by climate change; for example, energy-efficiency solutions and demand management.
For the efficient consumption product, framed within the Demand-Response initiatives, there was a saving of 63.17 MWh, which represents a reduction of 166.09 TonCO2.

Principal Results in 2022
GRI (3-3)
The investments made in Infrastructure and the new way of remunerating the assets by the regulator showed a growth of 24%, compared to the income of the previous year.
Investments worth COP 249,730 million were made in compliance with the Investment Plan approved within the framework of CREG Resolution 015 of 2018, which allowed us to maintain the indicators of quality and losses at optimal values.
During 2022 the results of the indicators were the following
Total Loss-Reduction Plan Celsia Colombia
Presented an indicator of 9.36%, exceeding the expected target by 0.02% (9.38%).
Presented an indicator of 12.89%, exceeding the expected goal by 1.83% (14.72%).

We obtained excellent results in the transformers impacted by the Optimus Project, which improved their quality indices by up to 25%. This project allows us to know, in real time, information about failures in the Company’s Distribution Transformers, without depending on client calls, using sensors in the secondary outputs of the Distribution Transformers.
Investment in T&D Innovation:
- We are part of the energy transformation, by modernizing the infrastructure of our networks. We have the AMI Project as the spearhead of this transformation, which presented the number of smart meters installed for 113,373 clients, with an investment in 2022 of COP 52.000 Billion, which included organic meters, façade meters, and centralized metering.
- The Digital Network (Red Digital, in Spanish) Project made investments for a value of COP 14.951 Billion, with which it has been possible to promote R&D+i for the digital transformation of the network and a sandbox, demand-response regulation, which provides good practices and technology references.
- Alliances with various suppliers and academia were strengthened through different initiatives with the Universidad del Valle, the National University of Colombia and allies such as IGT, Micol, PTI, Metrum and Colombia Inteligente, which encourage capacity building through participation in collaborative groups and energy clusters.
- Resources were managed with IFC and EPRI, which will allow the digital transformation of the network to be promoted.
for power transmission and distribution and for photovoltaic farms and roofs in Valle del Cauca and Tolima.
With this project we seek the transformation to enable a digitized, distributed, democratized and autonomous network in the Departments of Valle del Cauca and Tolima.
