Coal

TERMOELECTRICA MEJILLONES (CTM1) stands out as a key coal-fired power generation facility located in Chile, boasting a capacity of 318.9 MW. Operated by E-CL, this plant is an integral part of the country’s energy mix, particularly in the northern region where energy demand is high. Utilizing advanced coal combustion technology, the plant also incorporates petcoke as a secondary fuel, enhancing its operational flexibility and efficiency. The facility is situated at coordinates -23.0854° S latitude and -70.4100° W longitude, strategically positioned to serve the local grid and contribute to the overall energy supply for industrial and residential consumers. In the context of Chile’s energy policy, which faces the challenge of transitioning towards more sustainable sources while ensuring energy security, TERMOELECTRICA MEJILLONES represents a critical component of the current energy framework. While the country increasingly invests in renewable energy, the plant’s capacity remains vital to meet immediate power needs and stabilize the grid during peak demand. As such, this coal and petcoke power generation facility not only underscores the complexities of energy transition in Chile but also highlights the ongoing reliance on fossil fuels within the national energy strategy.
