PA's Jim Heidell, an energy expert, is quoted in an article in El Economista. The article discusses the recent pledge by the leaders of Mexico, Canada and the U.S. to have their countries produce 50% of their power from clean energy by 2025.
Commenting on the technical and economic challenges for the three countries, specifically for Mexico, Jim states: “The technical challenges imply that these nations must ensure that the transmission grid will be able to support the renewable resources because the power flows will inevitably change as power sources will shift from the thermal generation sites to the locations of the renewable resources. Another technical challenge is to ensure that there are enough flexible and fast-start thermal resources to complement the solar and wind intermittency.”
Jim concludes: “On the other hand, economic challenges will come from the potential early retirement of thermal generation, which becomes inefficient; the potential for thermal resources to be operated in a less economically efficient way; and finally the potential investments to maintain network reliability.”
