Portland City Council approved $107 million in clean energy grants Wednesday, the largest single investment in climate-related projects in the city’s history. The grants are funded through the Portland Clean Energy Fund (PCEF), a first-of-its-kind program that uses a surcharge on large retailers in the city to fund green energy projects that prioritize low-income Portlanders and communities of color. Last week, council members interrogated the grant recommendations and progress in grant vetting the program has.
