Energy associations warn of blackout risk and ask to activate thermal plants earlier due to high probability of El Niño

TL;DR

  • Colombia faces structural vulnerability in energy security with an 80% chance of El Niño and no energy surplus.
  • Current generation capacity is at a strict balance with projected demand, leaving no buffer for reduced hydroelectricity.
  • The system lacks energy reserves, unlike previous climate events, necessitating reliance on thermal power, especially coal.
  • A lack of expansion in backup infrastructure increases exposure to climate volatility.
  • Hydroelectric generation is projected to drop, activating the need for thermal plants in daily dispatch.
  • The coal sector can meet potential demand, with production capacity doubling the estimated requirement for a significant El Niño event.
  • Coal-fired power plants offer a cost-effective backup and are crucial for grid stability and wholesale electricity price formation.
  • The high cost of electricity during the last El Niño event ($1,600/kWh vs. $900/kWh normally) highlights the economic impact.
  • Industry associations urge the government to implement incentives for energy consumption reduction proactively.
