During 2021, ACENOR has made available the main electricity sector statistics related to electricity free customers, which are based on official figures published by the National Energy Commission and the National Electricity Coordinator.
Average Market Prices
- The average market price (AMP) is determined with the average prices of the contracts reported by the generation companies to the CNE, corresponding to a four-month window. Figure 1 includes the average market prices in real USD/MWh for 2021, in the National Electric System (SEN).
 Does not include utility charge, taxes (VAT or green tax) or stabilized price charge/benefit.
 For its calculation, the average UF value and the exchange rate observed for the months corresponding to the average market price published by the National Energy Commission have been used.
Average Price of Free Contracts in the National Electric System
-  Does not include public service charge, taxes (VAT or green tax) or stabilized price charge/benefit.
-  For its calculation, the value of the average UF and the exchange rate observed for the months corresponding to the average market price published by the National Energy Commission have been used.
Systemic or Lateral Positions
- Historically, the average market price has been the relevant indicator of electricity supply costs, incorporating energy and power charges. However, after the regulatory modifications of Law 20.936 in 2016, the so-called "lateral or systemic charges" must be considered, which are system costs that are financed pro rata to withdrawals, which facilitates their being passed on to end customers. Among the most important are the Ancillary Services.the Company also pays compensation for operations with variable costs above the marginal cost (Technical Minimums and cost overruns) and compensation payments for units under stabilized prices.
Lateral or systemic charges in 2021
-  Only the ancillary services Infrastructure is financed through a one-time charge to end customers.
Demanda Eléctrica de Clientes Libres
- Energy demand during 2021 increased by 4.5%, where electricity consumption of free customers increased by 4.9% compared to 2020. This represented a significant increase compared to the 2020 growth of 2.9% in non-regulated electricity customers, mainly due to the health emergency conditions caused by the Covid-19 pandemic.
Figure 3 shows the behavior of monthly energy consumption of free customers during 2021 in GWh, as well as the share of non-regulated consumption in total energy sales at the national level. On average, the free client market represented 61% of national consumption, similar to the figure for 2020.
- As for ACENOR A.G.'s associates, they represented 44% of the system's peak demand in 2020, which represents 22% of the national peak demand. Figure 4 includes the information in MW.
Maximum demand 2020 from non-regulated customers and ACENOR A.G. associates.
- Finally, it should be noted that ACENOR A.G. includes free customers of different sizes, which according to their connected power range from 8 MW to 2,246 MW.
