Reliability and Quality
Technical Losses
Technical losses are inherent to service provision; they are primarily due to the heating that occurs when the electrical energy passes through the transmission lines and transformers.
Technical losses
Total Losses
The total loss indicator (TLI) measures the integrated loss level from the 115 kV level. Total losses correspond to the total energy lost due to the effect of technical and non-technical energy losses, the latter representing the energy lost due to improper handling of equipment or billing systems.
Total Losses
System Reliability
Our efforts are focused on strengthening our network and the improvement and performance of our assets, so that clients have a reliable, continuous energy service.
System Reliability
SAIFI, SAIDI and CAIDI Indicators
SAIFI
The System Average Interruption Frequency Index (SAIFI) measures the frequency of power-service interruptions; that is, the amount of suspensions.

SAIDI
The System Average Interruption Duration Index (SAIDI) measures the duration of the energy-service interruptions.
SAIDI
CAIDI
(SASB: IF-EU-550a.2) Since 2021, we began to measure the Customer Average Interruption Duration Index (CAIDI), which represents the average time necessary to re-establish service once an interruption has occurred.

Smart Meters
Through the Advanced Metering Infrastructuring (AMI) Project, and as part of our plan to reduce losses, in Colombia we installed 65,000 smart meters, in Valle and Tolima.
We achieved a total of 251,433 meters in Valle and 36,430 meters in Tolima.
What is a smart meter? It is the latest technology available, which allows us to not only have a more-accurate record of client consumption, but also drives us to develop new products and services to make the most of the information that is beginning to be collected through these new devices.
Benefits for our clients:
- They will have a more-accurate measurement of their energy consumption.
- The meters allow remote reading and suspension; if the service is suspended and the system registers a payment, we can remotely reconnect it in less time.
- We will be able to detect any damage that occurs in the network in less time, which means that we will be able to attend to it more quickly.
- They will show an improvement in the quality of the service, since – in the areas where we have this technology – we have previously carried out a remodeling of medium- and low-voltage networks.
As of 2021, 9.0% of the measurement devices we use are smart meters.

Impact of Climate Change
TCFD (Strategy – b) Aware of the importance of climate change in all our businesses, we have identified new Risks that may impact some important aspects in the expansion and operation of the network, including:
- Alteration in the quality of service to our clients, due to heavy rains and strong winds.
- Affection in 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 sea-level rise and flooding.
However, we also find opportunities and have seen positive results in the initiatives implemented, thanks to the anticipation that has been taken, driven by climate change; for example, energy-efficiency solutions and demand management.
For the efficient-consumption product, frames within the Demand Response initiatives, there was a savings of 122.5 MWh, representing a reduction of 321.5 TonCO2, while with the AMI smart meters, the reduction was 1,731 TonCO2.
Main results
GRI (103-3)
The investments made in Infrastructure and the new way of remunerating the assets by the regulator showed a growth of 11%, compared to the income of the previous year.
Investments for COP 369.308 billion were made – 7.16% above the investments of the previous year – to comply with the projects defined by the Colombian Energy and Gas Regulation Commission (CREG, in Spanish) Resolution 015 of 2018, which allowed maintaining the quality indicators and losses in optimal values.
During 2021, the results of the indicators were as follows:
Total Loss Reduction Plan:
- Celsia Colombia Valle presented an indicator of 9.69%, deviating 0.3% from the expected goal (9.39%).
- Celsia Colombia Tolima presented an indicator of 13.44%, surpassing the expected goal by 1.79% (15.22%)
Quality Plan (SAIDI)
- Celsia Colombia Valle presented an indicator of 9.35 hours, improving the regulator-approved goal of 11.51 hours.
- CCelsia Colombia Tolima presented an indicator of 43.50 hours, improving the regulator-approved goal of 63.19 hours.
- CETSA presented an indicator of 1.61 hours, improving the regulator-approved goal of 2.44 hours.
We obtained excellent results in the transformers impacted by the OPTIMUS Project, which improved their quality indices by up to 21%. The OPTIMUS Project allows us to know in real time information about faults in the Company’s distribution transformers without relying on client calls, using sensors in the secondary outputs of the distribution transformers.
Investment in T&D Innovation in 2021:
- We continued advancing in the modernization of our infrastructure in the conformation of smart networks, having the AMI measurement as the spearhead of this transformation, which presented a growth of 65,000 clients, already reaching a cumulative figure of 287,863 clients with an investment of COP 31.075 billion.
- The Digital Network Project made investments worth COP 29.599 billion, where it has been possible to promote R&D+I for the digital transformation of the network and a regulatory sandbox for demand response, providing good practices and technology benchmarks.
- We strengthened alliances with various suppliers and academic through different initiatives with the Universidad del Valle, the National University, and allies, such as IGT, Micol, PTI, Metrum, Colombia Inteligente, where capacity building has also been encouraged through the participation in collaboration groups and energy clusters.
- We managed resources with IFC and EPRI, which will allow us to promote the digital transformation of the network.
- We developed skills and learning for electrical-storage solutions and connection to the distribution network, with an alliance with Terna, CESI and C3, companies that are experts in these technical issues.
