Ante los cambios a la Ley de la Industria Eléctrica, quisiera compartir un poco (bueno, mucho) de nuestro sistema eléctrico de BCS que opera más del 90% con combustóleo y diesel, sus apagones y lo que he aprendido estudiando este sistema, sus retos y el panorama poco alentador
🚀🌐 #EventosMéxicoEvalúa El 29 de abril presentamos el estudio “¡A romper barreras! Cómo detonar la inversión en México”.
En él encontramos que, si bien nuestra cercanía con 🇺🇸 es una gran ventaja, las trabas regulatorias nos frenan.
¿La clave? Atender las 3,015 áreas de oportunidad que detectamos en ocho estados estratégicos para el #nearshoring.
Aquí todos los detalles: https://t.co/jAsdz6OMl7
Muchas gracias por el espacio al @ElFinanciero_Mx. Aquí mi comentario sobre la columna que publicamos el día de hoy mi estimada @analiliamoreno y yo.
🔶️El dato: Pemex dedica 7.62% de su capex a sustentabilidad.
¿Cómo se compara con otras empresas? 👇🏼

2025: año de supuesta soberanía energética vs certidumbre a la inversión.
Producción petrolera mínima histórica y electricidad cada vez más insuficiente ...
Aquí va una recapitulación del año.
🧵🧵🧵
Un estudio de @mexevalua confirma que los subsidios de @CFEmx son regresivos y benefician más al decil más alto de la población.
"El problema es que al abaratar artificialmente el consumo, los subsidios desincentivan la eficiencia energética y presionan las finanzas públicas.
Cuando la energía se percibe como barata, se desperdicia más, se posterga la adopción de tecnologías limpias y el gobierno asume una carga fiscal creciente para sostener el esquema.
Una opción al subsidio sería resideñarlo: mantener el apoyo en los primeros bloques de consumo y reducirlo progresivamente en los niveles altos, o complementarlo con incentivos a la eficiencia y apoyos directos a los hogares más vulnerables."
Mi opinión para @ElFinanciero_Mx. Esta vez me tocó portada 💪
Gracias @HectorUsla por el espacio.
Actualización #tsunami por sismo de Kamchatka, Rusia.
🇲🇽El Centro de Alertas de Tsunami de México (CAT-SEMAR) emitió un boletín de seguimiento para costas de México. Se esperan variaciones del nivel del mar desde 30 cm hasta 1.0 m.
Por precaución, desde la 1:00 a.m. hasta que se cancele el boletín y haya pasado la amenaza, se recomienda no permanecer en las costas.
En imagen tiempo estimado de arribo de tsunami para costas de México y altura máxima esperada.
@azogueray@Carloslopezjone@Ursulaliber@vicfc7 Siempre será más barato tener la red de respaldo.
El solar no genera la misma capacidad todos los días.
La demanda no es la misma todos los días.
100% aislado requiere mucho sobredimensionamiento. Mejor conectarte a la red y comprarle y venderle.
Un gusto saludarlos estimados :)
¡No se pierdan el webinar de este lunes! ⭕️💻
Después de meses de trabajar aplicando una metodología de UNOPS, el equipo de @mexevalua comunicará los resultados.
👉🏼 Necesitamos + coordinación, transparencia y rendición de cuentas de camino a cumplir con las NDC.
Este es el hilo más objetivo que he encontrado sobre el colapso de la red eléctrica española y portuguesa. Es simple y sin sesgo de por medio. Va directo a lo técnico de una forma entendible para quienes lo leen.
Constantly shifting loads to provide an "impossible catchup cascade" IS the #1 attack vector for electricity networks.
Hence the pattern of the attack matches known attack vectors for a cyber based blackout attempt.
This appears to have been done on the renewable side.
Another way to conduct such an attack is IOT enabled electric ovens, devices able to create extremely massive (for a household) electric loads, who can quickly shut on and off without anyone noticing.
Do this on 150.000 ovens in a country, each pulling 3.500W, and quickly pulse them, and you have a 500+ MW variable load that starts such cascade.
SPAIN BLACKOUTS: AN ANONYMOUS EXPERT VIEW
From a deep groupchat, last night, translated from Spanish, written by an expert in transmission and distribution of power. Not my words.
"What has happened on April 28 has a well-located origin: the Aragón-Catalonia corridor, which is one of the most important electric highways in Spain. There is not only the electricity produced by our solar and wind farms in the northeast, but also the electricity that we import from France. This international interconnection, although weak (it can only contribute 3% of our demand, well below the minimum of 10% that marks the EU), in times of stress is essential to balance the network.
At 12:32 p.m., in that Aragón-Catalonia corridor there was an electric shock. What exactly does "shake" mean? It means that suddenly and abnormally, the power that flowed through those lines began to vary violently, rising and falling in a very short time. Such abrupt variability can be due to three main causes:
1. That a relay or transformer on that electric highway detects an abnormal flow of current or voltage (higher or lower than expected) and automatically disconnected to avoid burning or destroyed. This is called that "opens" a relay or switch: it jumps and cuts the passage of electricity to protect itself.
2. That the enormous concentration of renewable energy in that area (mainly solar and wind) has created an electrical resonance: electronic inverters, which synchronize current, can sometimes be amplified between them if a small voltage alteration (for example, due to clouds, strong wind or a slight failure) extends like an echo to all devices, causing widespread oscillations.
3. That a wrong control order has been sent (by mistake or attack) from the SCADA systems, disconnecting or reducing the generation of multiple hit plants. There is no confirmation of this possibility yet, but it is being investigated.
What is known is that as a consequence of that shake, the interconnection with France jumped: we were isolated just at the worst time, when the peninsula needed external support to stabilize.
Without that French help, the frequency of the peninsular network (which should always be 50 Hz exact) began to drop quickly. The frequency is like the heartbeat of the network: if it falls too much, the systems understand that the patient (the network) is collapsing and automatically disconnected so as not to self-destruct. Thus, in just five seconds, the solar and wind farms were turned off —very sensitive to frequency variations—, 15 GW of power was lost suddenly (60% of all the electricity generated at that time), and the network could not take it anymore: it was It collapsed completely, showing the Redeia Platform (REE) a "0 MW" nationwide. That does not mean that all the turbines were physically turned off, but there was no generator synchronized at the common frequency of 50 Hz. It was, for practical purposes, a country off.
To ignite a completely dead network again, one essential thing is needed: plants that can start in black, that is, without receiving energy from anywhere else. Spain has identified five large hydroelectric jumps capable of doing this. However, and here is one of the great negligences that are coming to light, three of those five groups were stopped in scheduled maintenance, by business decision supervised by the administration. Only two were operational. That made the recovery much slower and weaker than it should be in a normal contingency plan.
The result is that, after almost 10 hours, only 35% to 40% of the national supply has been recovered, and there are still large areas in the dark or under scheduled cuts.
The situation reveals a very serious underlying problem:
Spain is still an energy island: it only has 3% foreign exchange capacity compared to its total demand."...

¿Es de que por que se tardan en restablecer?
Para recordar y repasar. Todo tiene un proceso.
Aqui un hilo de hace tiempo sobre restablecimiento

La alta generación de electricidad con eólica y fotovoltaica no son las culpables del colapso del sistema eléctrico español y portugués. Si bien, la alta proporción puede causar que disminuya la inercia del sistema al no compensarse con inercia sintética, no es causa del colapso
Sugerir weaponization del gas natural por US vs México, es no tener un gramo de idea de la estructura del mercado. Un segundo tras que eso se deslice en una declaración y los primeros efectos serían sobre los productores, base política y financiera del partido hoy en el gobierno.
