Energy Alert – January 2025

COES Technical Procedures Nº 01 “Short-Term Operation Programming” (“PR-01”) and Nº 09 “Coordination of the Real-Time Operation of the SEIN” (“PR-09”) and the Glossary of Abbreviations of COES are modified

On January 21, 2025, Resolution Nº 003-2025-OS/CD was published in the Official Gazette “El Peruano”, which modifies the PR-01, PR-09 and the Glossary of Abbreviations of the COES in order to preserve the safety of the SEIN. This regulation is approved in response to the need to establish a criterion to reduce the electric generation produced with Renewable Energy Resources (“RER”) when the production of these technologies at any point of the National Interconnected Electric System (“SEIN”) exceeds the capacity of the transmission system.

The most relevant modifications are presented below:

Modifications to PR-01:

• Generation forecast as a criterion for operation scheduling: For SEIN operation scheduling, COES will consider the “generation forecasts” submitted by the generation owners with RER or COES’ own forecasts. This will allow greater reliability in the dispatch orders of each power plant, since they will take into account the electricity production estimates based on the characteristics of each energy source.
• Discharge allocation criteria: In the cases of zero (0) variable cost power plants that are connected at the same Connection Point and that inject their energy exclusively through the same link that reached its maximum capacity, the energy discharge in said node will be distributed according to the nominal power of each of said power plants.

Modifications to PR-09:

Measures deviating from the Daily Operation Program and Reprogram: The existence of greater (or lesser) availability of RER generation in a congested area is incorporated as a cause that enables COES to deviate from the PDO and RDO. In such cases, the COES may order energy discharges (or generation increases) of the plants that contribute at least 10% of their power in the congested element in proportion to their nominal power. These measures cannot cause negative marginal costs and, in case it happens, such values will be replaced by zero (0).

The COES shall annually inform OSINERGMIN about the occurrence of such situations.

Addition to the COES Glossary:

• Incorporation of the term “Energetic Dumping”: Energetic Dumping is defined as the scenario in which the zero (0) variable cost plants are limited to inject their generation to the SEIN due to the lack of capacity, for structural or temporary reasons, in the transmission grids or because there is a generation supply higher than the demand. The Energy Dump of a power plant corresponds to the amount of energy not generated in the described scenario.
