President Trump’s coal advisers canceled their two-day spring meeting slated to begin Tuesday because of the snow and sleet storm that hit Washington, as a group of some of the largest coal companies pressed the administration not to scrap clean coal programs in the budget to be released this week.

The focus of the National Coal Council meeting, March 14-15, was supposed to be on the novel technologies being developed by Exxon Mobil and others to make coal power plants competitive and climate friendly in the new century. The council represents top advisers to the Department of Energy on coal technology, and is expected to be tapped by Trump and Energy Secretary Rick Perry to develop policy recommendations to advance clean coal.Trump has made development of clean coal power plants a top priority during the next four years. However, he hasn’t said how he would do that. Janet Gellici, the council’s CEO, told the Washington Examiner that Perry hasn’t formally communicated to the council, yet, but the hope is that he would address the council this week. The spring meeting was developed ahead of Perry’s confirmation this month. But the council will have to wait to see if Perry will attend once it reschedules the meeting. “The National Coal Council leadership, in consultation with the U.S. Department of Energy, has elected to postpone the NCC’s 2017 Spring Annual Meeting scheduled for March 14-15 in Alexandria, VA,” a note from Gellici to attendees read Monday afternoon.
