The Mexican Energy Regulatory Commission recently issued a new regulation numbered A/113/2024 on how to integrate energy storage systems(EES)into the national power system.According to the International Energy Agency(IEA)report,Mexico is one of the fastest-growing regions in the global energy storage market.
According to Mexico’s Indicative Plan for Power Plant Installation and Decommissioning,from 2024 to 2038,Mexico plans to add 8412MW of Battery Energy Storage Systems(BESS).The new regulations require that energy storage devices must be registered like power plants and represented by power generation companies.This means that power generation companies can sell the electricity produced by these storage devices just like selling other types of electricity.
This regulation is the first step in a series of detailed regulatory regulations to be released this year.It clarifies several key points:
An auxiliary service market will be established to increase revenue from energy arbitrage.
To operate as a reliable power plant,the energy storage system must be able to store at least three hours of electricity.
Supervised the operation of BESS in self powered and exempted power generation modes.
In addition,there are five ways for BESS or EES to participate in the electricity market:
Independent power supply scheme
EES is included in power plants to meet their own needs or import and export electricity,and requires a power generation license or authorization.
Related to power plants
EES integration into existing or newly built intermittent power plants,sharing the same interconnection point,must comply with standards such as efficiency,quality,and reliability.
Related to load center
EES is integrated into existing or newly built load centers(excluding power plants),sharing the same connection point and not injecting electricity into the national power system.It can obtain energy supply through suppliers or participate in wholesale electricity markets.
Exemption related to generators
EES that complies with general administrative regulations,contract models,compensation calculation methods,and general technical specifications applicable to distributed power generation and clean distributed power plants.
Non associated EES
Battery based EES is not integrated into power plants or load centers,and its injection and/or consumption through the national transmission grid or general distribution network will be independently monitored,requiring a power generation permit.
Mexico has been committed to energy transition in recent years,with the goal of increasing the proportion of clean energy to 35%by 2030.The introduction of energy storage systems is seen as a key measure to achieve this goal,as it can address the intermittency issues of renewable energy sources such as solar and wind,and enhance grid stability.The release of the new regulations is expected to attract more domestic and foreign investors to enter the Mexican energy storage market,promoting the development of related industrial chains,including battery manufacturing,system integration,and energy management technology.
